+<h1><br />THE BOY VOLUNTEERS<br />
+WITH THE FRENCH<br />
+AIRMEN</h1>
+
+<h2><br />CHAPTER I</h2>
+
+<h2>ANTWERP AND THE FLIGHT THROUGH NORTHERN BELGIUM</h2>
+
+<p><br />Antwerp was in a fever of excitement, as Ralph
+and Alfred marched up from the quay with the
+Belgian troops, and rumors of an immediate attack
+on the city were flying about.</p>
+
+<p>"Look at the Zeppelin!" cried out a voice.</p>
+
+<p>The boys turned to follow the gaze of the people
+who lined the streets. There, almost directly
+west, they caught the first glimpse of one of the
+monsters which appeared to be moving south, far
+beyond the reach of the encircling forts, but
+plainly visible.</p>
+
+<p>"Nothing would suit me better than a trip in
+a flying machine!" exclaimed Alfred.</p>
+
+<p>"Wouldn't that be fine?" replied Ralph.</p>
+
+<p>The sight seemed to be an inspiration to the
+boys. Our story will tell how the idea so impressed
+itself on their minds that they almost felt<span class="pagenum"><a name="Page_14" id="Page_14">[Pg 14]</a></span>
+it a duty to join a flying corps. That, however,
+seemed to be an impossibility.</p>
+
+<p>They had passed through Belgium, participated
+in the first battles of the war, had been captured,
+and escaped from the Germans, and had now
+reached Antwerp, with the retreating Belgian
+army, where Ralph had hoped to meet his father,
+whom they had left in Germany almost four weeks
+prior to that time.</p>
+
+<p>As the father had not arrived, owing to the embargo
+which had been placed on all travelers from
+Germany to the warring countries, the boys found
+themselves stranded in a strange city. Fortunately,
+their connection with the army, and the
+fact that they had rendered Belgium some service,
+made it possible for them to get food and lodging.</p>
+
+<p>"We have forgotten one thing," said Ralph.</p>
+
+<p>"What is that?" inquired Alfred.</p>
+
+<p>"Why, we never went to the Post Office," replied
+Ralph.</p>
+
+<p>At the General Post Office they received a letter
+from Alfred's father, only to learn that he
+had been detained, as was the case with thousands
+of Americans, and that it would be impossible for
+him to reach Antwerp. Instead, he would be permitted
+to go through Switzerland, and from that
+country reach Paris where he hoped to meet them.</p>
+
+<p>"But we have no money now, what shall we
+do?" asked Alfred.</p>
+
+<p>"That's what worries me," answered Ralph.
+"Father supposes that Pierre is still with us, and
+that we are supplied with money."<span class="pagenum"><a name="Page_15" id="Page_15">[Pg 15]</a></span></p>
+
+<p>Three days after receiving the letter the boys
+heard the first definite news of the great movement
+of German troops designed to attack the forts. If
+they surrounded the city, and besieged it, the
+chances of reaching Paris would be small, indeed.</p>
+
+<p>"Something must be done, and that today,"
+said Ralph. "I am going to leave if I have to
+walk."</p>
+
+<p>"Where to?" asked Alfred.</p>
+
+<p>Ralph smiled, as he said: "We might walk to
+Holland."</p>
+
+<p>Alfred almost shouted for joy, as he exclaimed:
+"That's a good idea. We have about ten francs
+left; that ought to take us through."</p>
+
+<p>A map was consulted. "Why, yes," said Alfred,
+"we can go north to Eeckeren, and from that
+place to Capellen, close to the frontier. It's only
+twelve miles."</p>
+
+<p>After this decision they again visited the Post
+Office, and immediately crossed through the city
+with a view of striking the main highway leading
+to Holland. Reaching the outskirts of the city,
+they were surprised to see great masses of Belgian
+troops encamped close to the forts, which guarded
+the highway. They soon learned that a strong
+German column had reached Brasscheat, three
+miles from Eeckeren.</p>
+
+<p>They looked at each other in amazement.
+"Well, this beats everything," said Alfred, with a
+shade of bitterness. "The Germans seem to be
+in our way whichever direction we turn. We'll
+have to take another route."<span class="pagenum"><a name="Page_16" id="Page_16">[Pg 16]</a></span></p>
+
+<p>"Another route?" blurted out Ralph. "There
+isn't another way to go on this side of the river.
+It would be a long tramp to cross the river."</p>
+
+<p>They were now in a serious dilemma, and stood
+there undecided as to the best course to follow,
+when they were startled by a voice: "Hello,
+boys!"</p>
+
+<p>"It's Pierre!" shouted Alfred, who was the first
+to spy their friend.</p>
+
+<p>"And how did you get here?" asked Alfred.
+"We thought they had captured you at Rouen."</p>
+
+<p>"So they did, but we got away the same night.
+But where are you going?" returned Pierre.</p>
+
+<p>"Trying to get to Holland," he was informed.</p>
+
+<p>"I am afraid you will have to go south of the
+Scheldt to get there," Pierre then informed
+them.</p>
+
+<p>"But I received a letter from father, and he
+wants us to meet him in Paris," said Alfred.
+"You know we don't want to be shut up in the city,
+if the Germans are going to surround it."</p>
+
+<p>"Of course not," answered Pierre. "But in the
+meantime we must find some other way out. You
+know you are still in the army, in the messenger
+service, and come to think of it, you haven't received
+any pay so far, have you?"</p>
+
+<p>The boys laughed, for that part of it had been
+entirely forgotten.</p>
+
+<p>"Why, yes; the Germans paid us for work at
+the hospital," said Ralph.</p>
+
+<p>"And you repaid them by skipping out the next
+day," said Pierre with a smile.<span class="pagenum"><a name="Page_17" id="Page_17">[Pg 17]</a></span></p>
+
+<p>"How much do you think there is due us now?"
+asked Alfred.</p>
+
+<p>"I don't know what you are on the rolls for, but
+there must be a full month's pay due, and that
+would be about thirty-five francs apiece," said
+Pierre.</p>
+
+<p>"Thirty-five francs!" mused Ralph. "Twice
+thirty-five is seventy,&mdash;about fourteen dollars.
+Good, that will take us through."</p>
+
+<p>"I suggest that you come to headquarters and
+join us. We intend to cross the river. It will be
+the safest place for you," said Pierre.</p>
+
+<p>"That will suit me," said Ralph.</p>
+
+<p>Together they marched to headquarters where
+they were again installed and placed on the rolls.
+Late that night the regiment began its march,
+reaching the dock below Antwerp at ten o'clock,
+where they had a long wait before the crowded
+boats left the pier. On landing, the march was
+resumed, and did not halt for two hours, so it was
+nearly three in the morning before they were able
+to lie down for the much needed sleep.</p>
+
+<p>It did not seem that they had slept a half hour
+when they were awakened by the heavy booming
+notes of cannon, and the occasional rattle and
+crash of small guns. The boys now knew the kind
+of music which the different weapons ground out.</p>
+
+<p>"That's a machine gun, see how regularly the
+shots come," said Alfred.</p>
+
+<p>"Yes; and that's a salvo from infantry," replied
+Ralph. "The Mannlicher guns have an awfully
+snappy way of talking. Do you hear it?<span class="pagenum"><a name="Page_18" id="Page_18">[Pg 18]</a></span>
+There it is again. They must be rushing some of
+the outer works."</p>
+
+<p>The real fight, however, was between the forts
+and the heavy German guns, which continued during
+the entire day, principally on the southern and
+eastern sides of the city. The struggle was continuous
+for four days. Suddenly Pierre burst in
+with the startling information:</p>
+
+<p>"The Germans have silenced two of the forts,
+and Antwerp is doomed."</p>
+
+<p>No time was lost by the defending troops, and
+before noon the camp was dismantled, and the
+march begun.</p>
+
+<p>"Do you know where we are going!" asked Alfred.</p>
+
+<p>"Nothing more than that we are going to leave
+Antwerp, and try to reach the sea," replied
+Pierre.</p>
+
+<p>The Belgian army had begun its famous march
+across the northern end of Belgium in order to
+reach the sea, and secure the protection of the
+English fleet in the Channel.</p>
+
+<p>"I heard some one say that we intended going
+through Bruges," said Ralph.</p>
+
+<p>"Yes; and from there the army may be able to
+reach France, after passing through Ostend," said
+Pierre.</p>
+
+<p>In an air line Bruges is fifty miles from Antwerp,
+and from Bruges to the French frontier it
+is fully forty miles more. How the brave little
+army finally reached its destination, avoiding the
+large German forces sent out to intercept them,<span class="pagenum"><a name="Page_19" id="Page_19">[Pg 19]</a></span>
+remains one of the most glorious exploits in the
+history of the Belgian army.</p>
+
+<p>"Next to Belgium I am glad to be in France,"
+said Pierre. "Now you can get to Paris without
+difficulty," he added.</p>
+
+<p>It thus happened that six weeks after the boys
+entered Belgium southwest of Liege, they reached
+Dunkirk on the French coast, and saw the immense
+fleet of warships and transports, which the British
+had in the harbor. It seemed that every spot
+around the city was taken up by tents, wagons,
+mules, horses, and heavy guns, to say nothing of
+the soldiers on every hand.</p>
+
+<p>One regiment after the other entrained in cars,
+and were whirled to the south. Box cars, flat cars,
+some new, others dilapidated, were in service. It
+seemed that there were thousands of automobiles
+in line, and every one was anxious to get away.
+They even saw thousands of men, with full kits
+on their backs, march out to the east, as though
+they scorned to wait for railway or auto accommodations.</p>
+
+<p>Pierre was at the door of the boys' tent early in
+the morning of the second day. "I am glad to
+tell you that the roll has been signed, and you can
+get your pay," he said. "But I am awfully sorry
+to have you go."</p>
+
+<p>"Of course, we've had some pretty hard times,"
+said Ralph, "but it was a great experience.
+Maybe we'll come back again."</p>
+
+<p>"We're going to try to join the flying
+machines," said Alfred.<span class="pagenum"><a name="Page_20" id="Page_20">[Pg 20]</a></span></p>
+
+<p>Pierre laughed, and Ralph smiled, for, while
+that idea was uppermost in his mind, he had never
+discussed the subject with Alfred sufficiently to
+enable them to call it a plan that they really intended
+to follow out. It was more an enthusiastic
+feeling of something that they would like to do,
+without knowing just how they would go about it.</p>
+
+<p>"So you are really going to start for Paris this
+afternoon?" said Pierre.</p>
+
+<p>"Yes; we ought to be there now, for father will
+wonder what is the matter with us. You see he
+hasn't heard from us for six weeks, and it has been
+two weeks since we received his letter," said
+Ralph.</p>
+
+<p>"Then why don't you wire the Continental
+Hotel, Paris, and tell him you are on the way?
+It will relieve his anxiety. Tell him to answer you
+at once, for it may take you several days to reach
+Paris," said Pierre.</p>
+
+<p>"Several days?" queried Alfred.</p>
+
+<p>"Yes, indeed. Troops occupy all the cars now,"
+replied Pierre.</p>
+
+<p>So the telegram was sent, and it was decided to
+remain where they were until morning so as to
+receive the reply before starting. But no answer
+came that night or the next day. In the meantime,
+the boys wandered from place to place, for, as they
+still wore the trim Belgian suits, they were privileged
+to visit many places barred from civilians.</p>
+
+<p>In the afternoon they found themselves far
+down the road leading to Ypres, when they were
+startled at the sound of an unusual buzzing, and<span class="pagenum"><a name="Page_21" id="Page_21">[Pg 21]</a></span>
+soon divined the cause as they saw a dozen or more
+airplanes flying around over the broad fields to
+the east. Nothing more was needed to give the
+boys an inspiration. They moved toward the
+great field, as though a giant magnet pulled them.
+Long before they were near the hangars they could
+see the flyers far above them, circling about. The
+scene fascinated them.</p>
+
+<p>Then something like a dull explosion startled
+them, and they looked at each other and then
+glanced about.</p>
+
+<p>"There it is; look at it; directly above us,"
+shouted Alfred, in great excitement.</p>
+
+<p>"Something has happened; it's on fire," said
+Ralph.</p>
+
+<p>In an incredibly short space of time, something
+struck and rattled along the ground not far
+from them, but the machine, although falling, was
+still some hundreds of feet from the earth. One
+of the operators could be seen frantically drawing
+back the levers, and trying to hold the badly
+damaged ship from overturning, but his efforts
+were unavailing.</p>
+
+<p>The boys closed their eyes as the swiftly moving
+machine now actually rolled down through space,
+tumbling over and over, until it finally struck the
+ground with a crashing noise, not a hundred feet
+from where they stood. Terrorized at the sight,
+they stood still for a few moments, but this was
+no worse than the scenes they had witnessed in
+battle, so, without a word, they made a rush for
+the mound of debris.<span class="pagenum"><a name="Page_22" id="Page_22">[Pg 22]</a></span></p>
+
+<p>"They are both under the machine," said Alfred.</p>
+
+<p>"Look at the smoke; it's afire," shouted Ralph.</p>
+
+<p>"Use sand! use sand!" almost shrieked Alfred.</p>
+
+<p>They had early learned that sand is more effectual
+as a fire extinguisher of burning oil than
+water, if properly applied. Handsful of sand
+were scooped up and applied. A groan from one
+of the men arrested their movements.</p>
+
+<p>Alfred jumped on the broken mass, and peered
+down. "There he is!" he shouted. Ralph
+crawled over the broken body of the airplane, and
+reached down.</p>
+
+<p>"No; this man is lying still," he said. "Here
+he is; come on this side; he is under the framework."</p>
+
+<p>The scene was one which well might inspire
+heroic work.</p>
+
+<p>The imprisoned man was quite young, with
+handsome features, and it seemed cruel that such
+a fate should overtake him. The boys strained at
+the wreck until it moved.</p>
+
+<p>"Brace it up on that side," said Ralph.</p>
+
+<p>The truss from the fuselage was removed from
+the aviator, the man quickly drawn out from his
+perilous position, and carried clear of the wreck.</p>
+
+<p>"Now for the other one," said Alfred.</p>
+
+<p>Blood was still flowing across the face of the
+other flyer, as they crawled over the wreck to
+draw him out.</p>
+
+<p>"This one is alive, I am sure," said Ralph.</p>
+
+<p>"Why, yes; his heart is beating," replied Alfred,<span class="pagenum"><a name="Page_23" id="Page_23">[Pg 23]</a></span>
+as the injured men were laid side by side.</p>
+
+<p>"I have heard that they have first aid packages
+in machines of this kind," said Ralph, as he
+sprang toward the remains of the machine. "I
+have it," he cried, as he leaped over the wrecked
+pieces. "Here is&mdash;a&mdash;<i>Restorative</i>, whatever that
+is,&mdash;half a wineglass at a time,&mdash;where's the wineglass?"</p>
+
+<p>"Give each a good swallow of it," said Alfred,
+as he raised up the head of the one first rescued.</p>
+
+<p>The other man opened his eyes. "Lieutenant!"
+he said. Then, as he gazed at the boys, he seemed
+to smile, and as Alfred held up the bottle he feebly
+nodded.</p>
+
+<p>It seemed to revive him in a few moments, and
+he struggled to raise himself. "I feel better now,
+but something hurts my legs," he said.</p>
+
+<p>The lieutenant opened his eyes, and quietly
+looked at the boys without speaking.</p>
+
+<p>"Can I do anything for you?" said Alfred.</p>
+
+<p>"Is Jack hurt?" he asked.</p>
+
+<p>"Yes; but he is all right," said Ralph.</p>
+
+<p>"Here I am; still on top," said Jack, as he
+slightly turned, and moved his hand toward the
+lieutenant.</p>
+
+<p>"And what are you boys doing here?" asked
+the lieutenant.</p>
+
+<p>"On our way to Paris," said Alfred.</p>
+
+<p>"But where did you get the uniforms?" asked
+the officer.</p>
+
+<p>"Why, we've been in the Belgian army, and
+were in several fights," said Ralph proudly.<span class="pagenum"><a name="Page_24" id="Page_24">[Pg 24]</a></span></p>
+
+<p>The lieutenant's face brightened into a smile,
+which quickly changed to one of pain. An ambulance
+stopped alongside with startling suddenness,
+for the boys had been too busy to notice that
+the watchers at the hangars had signaled for assistance.
+The men were carefully carried to the
+van, and as they were about to start the lieutenant
+motioned to the doctor in charge, and said:</p>
+
+<p>"I want the boys to come along with us."</p>
+
+
+
+<hr />
+<p><span class="pagenum"><a name="Page_25" id="Page_25">[Pg 25]</a></span></p>
+
+<h2><br />CHAPTER II</h2>
+
+<h2>IN THE AVIATION CAMP</h2>
+
+<p><br />Once inside the ambulance the boys had an opportunity
+to watch the doctors, as they removed
+the clothing from the men, and began a search for
+the location and nature of the injuries. It was a
+gratification to be able to assist in this work.
+Jack's legs were both broken, and the lieutenant's
+chest, back and right arm were bruised and clotted
+with blood.</p>
+
+<p>"I think they are all right," said the doctor in
+charge.</p>
+
+<p>"But it's awfully hard breathing," said the lieutenant.</p>
+
+<p>"You must have had a pretty good weight on
+top of you," remarked the doctor.</p>
+
+<p>"I should think so," said Ralph. "It was all
+we could do to lift up the cross piece of the frame
+from him."</p>
+
+<p>"We'll straighten you out in a few days," answered
+the doctor, "but your companion didn't
+fare as well. Compound fracture of one leg; but
+he has a good constitution; he's good for several
+trips yet."</p>
+
+<p>The gratitude of the lieutenant was plainly observable,<span class="pagenum"><a name="Page_26" id="Page_26">[Pg 26]</a></span>
+and the doctor was quick to notice it.
+"If these young men hadn't taken you out when
+they did it would have been all over with you, because
+the weight prevented you from breathing."</p>
+
+<p>The lieutenant tried to smile, as he gazed at the
+boys, and they understood.</p>
+
+<p>When the ambulance reached the hospital there
+were fifty or more aviators from the station,
+awaiting the news. The boys leaped out, the attendants
+were on hand with the stretchers, while
+the excited men crowded around the boys to learn
+the details. It was not long before the story of
+the rescue was known. The chief of the flying
+squadron came out of the hospital, and approached
+the boys. The latter straightened up
+and saluted.</p>
+
+<p>"You should be commended for the prompt
+work you performed in rescuing the lieutenant
+and his pilot. I understand you belong to the Belgian
+army; but you are not Belgians, are you?"
+he asked.</p>
+
+<p>"No, we are not," said Alfred, slightly embarrassed
+at the question.</p>
+
+<p>The Commandant smiled as he continued: "I
+take it that you are Americans?"</p>
+
+<p>"Yes, Captain; you are right," replied Ralph.
+"We joined the Belgian army at Liege, and fought
+the enemy all the way to Antwerp, and we had
+some pretty hot times, too."</p>
+
+<p>This speech was applauded heartily, while a
+young man sprang forward, held out his hand and
+said: "And here's United States, too."<span class="pagenum"><a name="Page_27" id="Page_27">[Pg 27]</a></span></p>
+
+<p>"We are not with the army now," said Alfred,
+recovering; "we hope to go to Paris, if it is possible
+to get there."</p>
+
+<p>"The chances for that are not very good at
+present," observed the Commandant, "but in the
+meantime, if you are not attached, you must put
+up with us."</p>
+
+<p>"Thank you for the offer," said Ralph eagerly.
+"We want to get into the flying service; that will
+just suit us."</p>
+
+<p>"I am afraid that the army provisions would
+not permit you to join," said the officer, and all
+noted the expressions of disappointment that indicated
+the boys' feelings at this announcement.</p>
+
+<p>"Then I suppose we'll have to force our way in,
+just as we did in Belgium," said Alfred.</p>
+
+<p>This was greeted with a sally of laughter. The
+boys had made a hit with the corps, and they accepted
+the offer of quarters for their accommodation
+in the firm belief that something would turn
+up to assist them in their desires.</p>
+
+<p>Boys are really at a disadvantage sometimes.
+This story, as well as many others, shows that
+they are capable of doing things as well as men,
+and that they can do some things better than
+most men; but in military matters the service
+seems to have been made for grown-up people on
+the principle that war is too barbarous a thing
+for young men until they are twenty years of age.</p>
+
+<p>The boys, who were now in their glory, had a
+portion of a small room in a wooden building assigned
+to them. At this time there were fifty machines<span class="pagenum"><a name="Page_28" id="Page_28">[Pg 28]</a></span>
+of various types on the ground, the particular
+makes being the Bristol, the B. E., several
+Farman machines, and a half dozen Sopworth
+tractors.</p>
+
+<p>Tom Walton, the young American who greeted
+them at the hospital, was accorded the privilege of
+escorting the boys and introducing them. That
+they had been in the first battles of the war was
+sufficient to give them a coveted place in that company
+of enthusiastic men, for there was some
+glory in having been on a battlefield,&mdash;a thing
+which could have been said of only a few of those
+who entertained them that day.</p>
+
+<p>"I suppose you want to see the machines," said
+Tom.</p>
+
+<p>"Indeed, we do," said Alfred. "What is that
+big machine over there?"</p>
+
+<p>"That is a Bristol," answered Tom.</p>
+
+<p>"And there is another one," remarked Ralph,
+pointing to a machine, which was being drawn out
+of the hangar.</p>
+
+<p>"No, that's a B. E. biplane," answered Tom.
+"You will see the difference by observing the
+shape of the planes. The Bristol has the ends of
+the wings rounded so that the forward corners are
+cut away to a greater extent than the rear corners.
+In the B. E. the wings are cut to conform with the
+well-known Wright type."</p>
+
+<p>"That's a Farman machine, I know," said
+Ralph, pointing to an aeroplane which had a huge
+revolving type of motor forward of the main
+planes.<span class="pagenum"><a name="Page_29" id="Page_29">[Pg 29]</a></span></p>
+
+<p>"Yes; but when that machine is high in the air
+it would be difficult to recognize it from that description,"
+said Tom. "You will notice that the
+lower plane is much shorter than the upper plane,
+and that it has a great spreading tail,&mdash;larger
+than any other machine now made."</p>
+
+<div class="figcenter" style="width: 526px;">
+<img src="images/illus025.jpg" width="526" height="400" alt="Types of Allied Airplanes" title="" />
+</div>
+
+<p>"Here is another kind, a little fellow. That
+certainly looks different from all the others," said
+Alfred, as they stopped in front of a hangar.</p>
+
+<p>"That's the Sopworth tractor, a fine, speedy
+machine, with square ends to the planes, and a
+heart-shaped tail. It can be distinguished at any
+altitude," answered Tom.</p>
+
+<p>"I notice that that has different tails," said
+Ralph. "Does that make any difference in the
+flying?"</p>
+
+<p>"Not in the least. Shape has nothing to do with<span class="pagenum"><a name="Page_30" id="Page_30">[Pg 30]</a></span>
+it. Surface is all that counts. They are made
+with distinctive forms so that they may be easily
+distinguished, one from the other."</p>
+
+<p>"We saw some German airplanes, several dozens
+of them, in Belgium, and the only one I could
+recognize was the Taube, as they called it. They
+have fan-shaped tails," said Alfred.</p>
+
+<p>"But here is the machine for business," said
+Tom, as they halted in front of a gaily decorated
+hangar, and pointed to a trim little machine, which
+was being overhauled.</p>
+
+<p>"I see you have the Stars and Stripes above the
+door," said Ralph.</p>
+
+<p>"Yes; and this is my machine; isn't it a
+beauty?" said Tom with a considerable show of
+pride.</p>
+
+<p>"What is it? I mean what make?" asked Alfred.</p>
+
+<p>"It is a French Morane; I have made many
+trips in it," said Tom, "and now I am going to
+use it against the Dutchies."</p>
+
+<p>Thus they were conducted from place to place,
+visited the machine shop, which had been set up
+for repairs, and then inspected the landing field,
+which was designed to be illuminated for night
+work.</p>
+
+<p>"Do you mean to say that you use the flying machines
+at night?" asked Ralph.</p>
+
+<p>"Why, certainly; that is going to be a great
+stunt," said Tom. "The only trouble is that
+where there are many lights about it is pretty hard
+for a pilot to hunt out the landing place, so the<span class="pagenum"><a name="Page_31" id="Page_31">[Pg 31]</a></span>
+authorities have made special provision for returning
+aviators to enable them to land with as
+much safety as in the daytime."</p>
+
+<p>"How is it arranged so they can land without
+a mistake?" asked Alfred.</p>
+
+<div class="figcenter" style="width: 536px;">
+<img src="images/illus027.jpg" width="536" height="400" alt="Airplanes of the Central Powers" title="" />
+</div>
+
+<p>"Do you see that tall pylon, over there?" replied
+Tom. "That has on it the pilot light, much
+more brilliant than anything in sight. Now, look
+over to the left, nearly a quarter of a mile away;
+that pylon carries a brilliant red light. The other
+two pylons to the north and to the south have blue
+lights. The aviator knows that the bright light is
+to the east of the red light, and that he must make
+a landing somewhere between the brilliant light
+and the red light, between the limits marked by
+the blue lights."</p>
+
+<p>"I should think that would be easy," said
+Ralph.<span class="pagenum"><a name="Page_32" id="Page_32">[Pg 32]</a></span></p>
+
+<p>"It is when the night is clear; but the trouble
+is that the fog from the channel gives us considerable
+trouble, and then we have to glide back and
+forth very low to get our bearings, and that is
+dangerous business in the night."</p>
+
+<p>The inspection raised the enthusiasm of the boys
+to the highest pitch. For them there was now no
+other life than flying, and, indeed, things seemed
+to be coming their way. They had learned more
+about machines during the two hours thus spent
+than they had acquired in all their lives previous
+to that time.</p>
+
+<p>"I want to ask a favor of you," said Alfred,
+as they were returning to their quarters.</p>
+
+<p>"Go ahead," said Tom.</p>
+
+<p>"I would like to go up in a machine with you,"
+was the reply.</p>
+
+<p>Tom stopped, and looked at Alfred. "Do you
+really mean it?" he asked.</p>
+
+<p>"Of course I do," replied Alfred.</p>
+
+<p>"That's what I want to do, too," chimed in
+Ralph.</p>
+
+<p>"It's against the rules to take up any one but
+the observers during practice hours; but let me
+see,&mdash;we may be able to fix it up some other time,"
+said Tom.</p>
+
+<p>"Do you have to do much practicing?" asked
+Alfred.</p>
+
+<p>"Only from six to eight hours a day," answered
+Tom.</p>
+
+<p>"What! do you mean practice flying when you
+are not scouting?" asked Ralph.<span class="pagenum"><a name="Page_33" id="Page_33">[Pg 33]</a></span></p>
+
+<p>"Well, I should say so," was the answer.</p>
+
+<p>"How long have you been flying?" asked
+Ralph.</p>
+
+<p>"About two years," said Tom.</p>
+
+<p>"And still they make you fly every day, for
+practice?" asked Alfred.</p>
+
+<p>"Of course," said Tom.</p>
+
+<p>"And what is that for?" asked Alfred.</p>
+
+<p>"Flying airplanes for war purposes is something
+different to ordinary flying. The principal
+practice is to learn the methods of attack and defense.
+But that is not all. The airplane is the
+eye of the army; the observer must know how to
+observe. He must be able not only to see, but to
+put his knowledge into such form that it can be
+handed in in the form of a report. While he may
+get the information he must learn that the information
+is not for his own gratification, but for the
+use of the men in the field," said Tom.</p>
+
+<p>"Do all the machines carry a pilot and an observer?"
+asked Ralph.</p>
+
+<p>"Not by any means," answered Tom. "The
+first duty of a pilot is to learn how to control his
+machine when approaching an enemy, and how to
+attack or to avoid him. For that purpose he has
+a machine gun which he uses in flying."</p>
+
+<p>"I had no idea that there was so much to do in
+the business," said Alfred.</p>
+
+<p>"That is only part of the practice," continued
+Tom. "The most interesting part of the work is
+to practice flying in squadron formation, to observe
+the signals of the commanding officer and to<span class="pagenum"><a name="Page_34" id="Page_34">[Pg 34]</a></span>
+execute movements. For this purpose two squadrons
+oppose each other, and sally forth, the object
+being to judge the objects of an attacking
+force and to devise means to repel the enemy."</p>
+
+<p>The boys sat on their improvised bunks until a
+late hour that night. They discussed the airplanes;
+the men they had met; their work in rescuing
+the fallen aviators, and the things they had
+learned in this, to them, the most eventful day.</p>
+
+<p>"I wonder what father would say if he knew we
+were going to join the aviation corps?" said Alfred.</p>
+
+<p>"Well, I wonder what he will say when he hears
+what we were doing in Belgium," replied Alfred.</p>
+
+<p>"He must have gotten our letters by this time,"
+said Ralph.</p>
+
+<p>"Then why doesn't he answer our telegram?"
+asked Alfred.</p>
+
+<p>"Why, we forgot to go back to the city and inquire
+for it," said Ralph.</p>
+
+<p>"That's so; but we've been too busy for that;
+we must do that the first thing in the morning,"
+said Alfred.</p>
+

+
+<h2><br />CHAPTER III</h2>
+
+<h2>THE WOUNDED AVIATORS</h2>
+
+<p><br />They were out early the next morning, and
+started for the tramway a mile distant. They
+passed Tom's hangar, and stopped for a moment
+to take a look at his machine. As they were leaving
+they heard his voice:</p>
+
+<p>"Going to leave us?" he inquired.</p>
+
+<p>"No; but we must go to the city to get our
+mail, and we are expecting a telegram," shouted
+Ralph.</p>
+
+<p>"Get back by eleven o'clock if you can," was
+the answer.</p>
+
+<p>"We'll be here, sure," said Alfred.</p>
+
+<p>"He must mean that we can have a try in the
+machine at that time, I suppose," remarked
+Ralph.</p>
+
+<p>"I imagine that's why he wants us back then,"
+answered Alfred.</p>
+
+<p>They covered the mile in record time. The idea
+of going up in a machine was a stimulus, and they
+talked about it all the way, and wondered what it
+would feel like to sail above the earth in a war-machine.</p>
+
+<p>At the post office they had their first disappointment,<span class="pagenum"><a name="Page_36" id="Page_36">[Pg 36]</a></span>
+and there was nothing at the telegraph office.
+They were perplexed at the absence of news,
+but consoled themselves with the thought that
+transportation from the Swiss frontier might be
+in the same condition as at the Western front, so
+they decided they would not remain long in the
+city.</p>
+
+<p>The city, containing a population of about
+40,000, is located on the sand dunes. It takes its
+name from the old church of St. Eloi, and means
+<i>church on the dunes</i>. It has been in existence for
+over a thousand years, and was owned by the
+Dutch, the Spaniards, and the English, before it
+became permanent French territory.</p>
+
+<p>Passing through the principal square, on their
+way to the terminus of the tram cars, they saw
+crowds of people moving toward the main landing
+place of vessels. They followed, and witnessed
+the debarkation of the first vessel load of
+Red Cross supplies, accompanied by a large corps
+of physicians and Red Cross nurses.</p>
+
+<p>Fully fifty vans were taken from the ship and
+lined up, with their equipments, ready for a
+prompt start. A number of lorries (large motor
+trucks), carrying beds, bedding and like material,
+followed, and were placed behind the vans.</p>
+
+<p>"Do you know where they are going?" asked
+Ralph, addressing a young man in uniform.</p>
+
+<p>"To the general hospital, where they will be assigned
+to stations near the front," he replied.</p>
+
+<p>"Do you mean the general hospital near the
+aviation ground?" inquired Alfred.<span class="pagenum"><a name="Page_37" id="Page_37">[Pg 37]</a></span></p>
+
+<p>"Yes," was the answer.</p>
+
+<p>"Probably we can get a chance to ride there,"
+said Ralph, addressing Alfred.</p>
+
+<p>The man overheard the remark, and quickly
+turned to the boys.</p>
+
+<p>"Are you attached to the flying squadron?" he
+asked.</p>
+
+<p>"Yes," replied Alfred.</p>
+
+<p>"Then they wouldn't object, I am sure,"
+answered the officer, and he strode forward.
+After speaking a few words to one who seemed to
+be in charge, he motioned to them.</p>
+
+<p>"Get in, boys," he said.</p>
+
+<p>They were quick to respond, and, after thanking
+the officer, mounted one of the vans. Inside
+were three nurses and two physicians, who smiled
+at the boys.</p>
+
+<p>"So you are going to war, too?" said one of
+the nurses, as she made room for them.</p>
+
+<p>"Yes," said Alfred, rather shyly; "we are
+going back."</p>
+
+<p>"Going back?" remarked one of the doctors.
+"Did you say 'going back?'" he inquired.</p>
+
+<p>"Well, we were with the Belgian army from
+Liege to Antwerp, and came across the northern
+part of Belgium with them," said Alfred.</p>
+
+<p>"Then you must have seen some fighting?"
+asked one of the others, much interested.</p>
+
+<p>"Yes, indeed; we were in the first battles of the
+war," said Ralph.</p>
+
+<p>The information was certainly an interesting
+bit of news. From that time on the boys were the<span class="pagenum"><a name="Page_38" id="Page_38">[Pg 38]</a></span>
+center of interest, and many questions were plied
+and answered.</p>
+
+<p>"But where are you bound now?" asked one of
+the doctors. "If I understand correctly, you are
+attached to the aviation corps, is that so?"</p>
+
+<p>"Yes, we are being put up by them, and we may
+do some flying in a few days," said Alfred.</p>
+
+<p>"We do hope you will be successful," said one
+of the nurses. "Won't you tell us where you are
+from?"</p>
+
+<p>"We are from New York," said Alfred.</p>
+
+<p>"Then you are not English?" she asked.</p>
+
+<p>"Oh, no," replied Alfred. "But that doesn't
+make any difference. It's just the same as though
+we were English. We want to help out."</p>
+
+<p>There was a merry roar of laughter at this, and
+Ralph immediately chimed in with a sort of explanation:
+"The Germans didn't treat us right,
+when they captured us, and, anyhow, they had no
+business to attack Belgium."</p>
+
+<p>"Good for you," said a sweet little miss. "We
+like Americans, and especially those like you who
+have that spirit."</p>
+
+<p>The vans covered the ground to the general hospital
+in quick time, and the boys were really sorry
+when the van drew up before the building, but
+they quickly recognized the place where they had
+accompanied the injured aviators the previous
+day.</p>
+
+<p>"Ralph, we ought to go in and see the lieutenant
+and Jack," said Alfred.</p>
+
+<p>"Who are they?" interposed the doctor.<span class="pagenum"><a name="Page_39" id="Page_39">[Pg 39]</a></span></p>
+
+<p>"Why, they fell with their machine yesterday,
+and we helped them out," said Alfred.</p>
+
+<p>"What was the lieutenant's name?" asked the
+doctor.</p>
+
+<p>"Why, we don't know; we forgot to ask for it;
+but maybe they will let us in," said Ralph.</p>
+
+<p>"Come along," said the doctor. "We'll find a
+way to get in."</p>
+
+<p>They followed him up the steps, and marched to
+the office, where the doctor was greeted by many
+of those present.</p>
+
+<p>"Who was it that met with an accident yesterday?"
+he asked.</p>
+
+<p>"Lieutenant Winston," was the reply.</p>
+
+<p>"And was he badly hurt?" almost shrieked the
+sweet little nurse who had accompanied the party
+in the van.</p>
+
+<p>"No; he is getting along well," said the attending
+physician. "He owes his life to a couple of
+brave lads, who happened to be near. He has been
+anxious to see the boys, and has asked where they
+were."</p>
+
+<p>"We are the ones who helped him," said Ralph.
+"We want to see him; may we?"</p>
+
+<p>"Oh, thank you, thank you so much," said the
+nurse.</p>
+
+<p>"Do you know him?" inquired Alfred.</p>
+
+<p>"He is my brother; may we go to him at once?"
+she asked.</p>
+
+<p>"I will take you to him," said the physician.</p>
+
+<p>"So you are Miss Winston?" said Alfred.
+"Isn't it funny how we happened to meet you?"<span class="pagenum"><a name="Page_40" id="Page_40">[Pg 40]</a></span></p>
+
+<p>She almost hugged the boys in her joy at the
+news, and at her good fortune in thus meeting the
+boys who were instrumental in saving her
+brother.</p>
+
+<p>The lieutenant saw his sister approaching arm
+in arm with the two boys. The greeting was a
+most affectionate one.</p>
+
+<p>"I met the two boys in Dunkirk; they just happened
+to get into our van. We learned after we
+got here what they had done. Isn't it noble of
+them?" she said.</p>
+
+<p>"I have tried to find them all day," said the
+lieutenant, and he pressed the hands of the boys.
+"Yes, I was in an awfully tight place when the
+boys found me; but I am all right now."</p>
+
+<p>They remained with the lieutenant and his sister
+for more than an hour. They had entirely forgotten
+their appointment with Tom. It was nearly
+twelve o'clock.</p>
+
+<p>"I am afraid we shall have to leave you," said
+Ralph. "We promised Tom to be over at the
+hangar at eleven."</p>
+
+<p>"Tom Brandon; the American dare-devil?"
+said the lieutenant, smiling.</p>
+
+<p>"Why, yes," replied Alfred, somewhat hesitatingly.
+"Is he a dare-devil?" he continued, with
+wide-open eyes.</p>
+
+<p>"Well, he doesn't seem to be afraid of anything;
+I suppose he would go anywhere, if he was
+ordered to make the trip. Is your engagement an
+important one?" asked the lieutenant, with a curious
+light in his eye.<span class="pagenum"><a name="Page_41" id="Page_41">[Pg 41]</a></span></p>
+
+<p>"Why,&mdash;yes,&mdash;we&mdash;we wanted to take a flight
+this afternoon," said Ralph.</p>
+
+<p>"Do you think they would let us?" asked Alfred
+quickly.</p>
+
+<p>"Rather against the rules and somewhat risky,"
+said the lieutenant, slowly shaking his head, but
+his face relaxed, as he saw the crestfallen appearance
+of the boys. "We can get around the rules
+sometimes," he added.</p>
+
+<p>"Tom said he would try to fix it for us," said
+Ralph.</p>
+
+<p>"Then go at once, and tell him that Winston
+gave him permission," said the lieutenant. "Do
+you think it is safe, Addie?" he asked, turning to
+his sister.</p>
+
+<p>"It seems to me it is safe to trust boys who
+have been in battles as they have, don't you?"
+she replied sweetly, as she arose and grasped the
+boys' hands. "Now, don't forget us, will you?"</p>
+
+<p>"No, indeed; we intend to come over to see you
+in the morning," said Ralph.</p>
+
+<p>The boys fairly flew across the broad grounds
+in order to reach the hangar. Their chagrin was
+great as they peered in to find that Tom and his
+machine were absent.</p>
+
+<p>"Looking for Tom?" asked one of the men.</p>
+
+<p>"Yes; do you know where he is?" asked Alfred.</p>
+
+<p>"He's coming now, I think," was the reply, as
+the man approached the door and glanced upward.
+"Yes; there he is, winging it in."</p>
+
+<p>Within two minutes the Morane gave a quick<span class="pagenum"><a name="Page_42" id="Page_42">[Pg 42]</a></span>
+dive, then flattened out and skimmed the ground,
+and just before alighting the nose of the machine
+gave a short, quick, upward dart.</p>
+
+<p>"He does that the slickest of the whole lot.
+That was a quick stop, sure enough," remarked
+an attendant.</p>
+
+<p>The machine had landed not two hundred feet
+from the hangar. The boys were over without
+delay, and accosted Tom, as he reached the
+ground.</p>
+
+<p>"We are sorry that we couldn't get here in
+time, but we met Lieutenant Winston's sister coming
+over, and we were detained at the hospital,"
+said Ralph.</p>
+
+<p>"It's just as well, as I couldn't make it. The
+commandant wouldn't give me the time to take
+you out," said Tom.</p>
+
+<p>"But the lieutenant told us to tell you that he
+gave you permission to take us," said Alfred.</p>
+
+<p>"Did he say that? Well, that's another thing.
+I'll tell the commandant," and, without another
+word, he crossed the field, and disappeared. He
+was back in five minutes, and waved his hat as he
+appeared.</p>
+
+<p>"All right, boys; we'll have an hour's flight;
+how will that suit you?" he said.</p>
+
+<p>The boys were too much excited to know what
+to say in reply. Tom walked around the machine,
+observing every part of the control plane and the
+wires, then mounted the chassis, and with a wrench
+unscrewed the base of the machine gun.</p>
+
+<p>"Here, boys; we'll take this off for the afternoon;<span class="pagenum"><a name="Page_43" id="Page_43">[Pg 43]</a></span>
+it'll give you more room. There, take hold
+of it at both ends, and carry it into the hangar,"
+he said, as he handed down the weapon.</p>
+
+<p>"Gee! but that weighs something!" said Ralph.</p>
+
+<p>"Close to eighty pounds, I should say," observed
+Tom.</p>
+
+<p>"Where shall we sit?" asked Alfred.</p>
+
+<p>"You can easily crowd into the hole in front,"
+said Tom. "Now don't get frightened and jump
+out; I can bring you down easier than that. If
+it seems to turn over, don't mind. That's part
+of the game."</p>
+
+<p>The Morane was equipped with a self-starter,
+but three attendants were on hand to hold the machine.
+They took their places and Tom turned
+on the switch. Whir-r-r-r-r,&mdash;they felt the tremor
+of the machine. Soon Tom's hand was raised and
+came down with a swift motion. They felt the
+machine slowly gain headway, and then it seemed
+to spring forward with huge leaps. At first they
+could feel the oscillating motion of the wheels,
+and as the speed increased there was less jar until
+finally there was no further vertical movement,
+and they no longer felt the wheels traveling over
+the ground.</p>
+
+<p>"We're up!" shouted Ralph in excitement, as
+he turned to Tom. The latter evidently knew what
+Ralph meant, even though the noise of the motor
+prevented him from hearing, for he merely smiled,
+and shook his head.</p>
+
+<p>Alfred leaned over the side of the body, and
+gazed at the wheels, and as he did so something<span class="pagenum"><a name="Page_44" id="Page_44">[Pg 44]</a></span>
+seemed to push the seat of the aeroplane upwardly.
+He quickly turned toward Tom and
+smiled. They were in the air. How glorious it
+seemed to Ralph and Alfred at that moment. The
+feeling was an indescribable one; they were now
+going up rapidly; ahead was a tall pylon, which
+seemed to be directly in their way.</p>
+
+<p>Ralph seized Alfred's arm, and pointed toward
+it, their eyes being intently fixed on the square
+flag which flew above the mast, but the machine
+seemed to whiz by it like a streak. After passing
+it the machine seemed to slow down. They were
+not aware that the closer you are to an object the
+faster seems to be the motion. Looking down at
+the earth they could note an object for some time,
+and as they went further up and up, things on the
+earth seemed to pass by with less and less speed.</p>
+
+<p>The most confusing thing to them was the constant
+change of position. Instead of making a
+straight-away flight Tom circled around the aviation
+field twice, going higher on each turn. The
+great hangar was plainly visible each time they
+came around, but it grew smaller and smaller.</p>
+
+<p>The boys leaned over the body of the machine,
+and scanned the earth below. It was too grand
+and inspiring for words. It was some time before
+they began to realize that the hangars were
+disappearing, and that the machine was now going
+forward in one direction. The country below was
+a confused maze of narrow yellow streaks, bordered
+by green and yellow spots, with innumerable
+rows of dark green and brown bands and<span class="pagenum"><a name="Page_45" id="Page_45">[Pg 45]</a></span>
+patches, which they soon recognized as trees, while
+cottages and larger buildings dotted the whole
+landscape as far as the eye could reach.</p>
+
+<p>Alfred was the first to cast his eyes to the
+north. What he saw almost startled him. A dark
+vivid green spread to the horizon, blending with
+a pale mist, far, far away.</p>
+
+<p>"Look! look!" he cried.</p>
+
+<p>"That's the sea!" shouted Ralph.</p>
+
+<p>Tom smiled as he reveled in their joy. He
+pointed ahead, and the boys quickly turned. Far
+off, in the distance, they saw what seemed to be
+immense fields of snow.</p>
+
+<p>"What can that be?" asked Ralph.</p>
+
+<p>Alfred shook his head, and gazed silently, then
+turned toward Tom. "Can you make it out?" he
+asked Ralph. The latter shook his head.</p>
+
+<p>The machine went on for ten minutes more. Beyond
+the white fields something else arrested their
+attention; great clouds of smoke were observed.
+They were not clouds, and there was no fire visible
+on the earth. That was the second mystery.</p>
+
+<p>"I know what that is now," said Ralph.</p>
+
+<p>"What is it?" asked Alfred.</p>
+
+<p>"Tents, tents," said Ralph.</p>
+
+<p>"Yes, and that smoke must come from the big
+guns," said Alfred.</p>
+
+<p>Ralph turned his head toward Tom, and raised
+his cap. The latter knew that the boys recognized
+the nature of the scene before them.</p>
+
+<p>"That must be a battle," said Alfred, as he
+pointed to the great clouds of smoke.<span class="pagenum"><a name="Page_46" id="Page_46">[Pg 46]</a></span></p>
+
+<p>"Look way over to the left," shouted Ralph.
+"See that long, narrow road? There is something
+moving there."</p>
+
+<p>"Why, that is cavalry; sure enough. See, they
+are turning a corner in the road. That's plain
+enough," said Alfred.</p>
+
+<p>"I wonder if he is going to take us over the
+German lines?" queried Ralph.</p>
+
+<p>"And suppose something happens, and we are
+compelled to go down; we'll be in a nice fix," remarked
+Alfred.</p>
+
+<p>Ralph shook his head, and glanced back toward
+Tom. The latter, however, soon turned the machine.
+As he did so a dozen or more aeroplanes
+came into view. They noticed that the machine
+was going toward a field where a huge gas bag was
+moored near the ground. It was an observation
+balloon. Beyond were several dozens of flying
+machines drawn up in front of the hangars. Tom
+circled the machine around several times; the
+earth came nearer, and soon they observed a long
+stretch of green that seemed to invite them. In
+another minute they were several hundred feet
+from the earth, and they seemed to go faster and
+faster.</p>
+
+<p>"Whew! but doesn't it scoot now," said Alfred.</p>
+
+<p>They grasped the body of the car, while it
+seemed to fairly sizzle through the air. Closer
+and closer the earth crept up toward them. They
+felt that it would be necessary to hold fast when<span class="pagenum"><a name="Page_47" id="Page_47">[Pg 47]</a></span>
+the shock came. The next sensation was most
+peculiar; the body of the car began to rock up
+and down; the din of the motor had ceased, and
+they were riding on the earth.</p>
+

+
+<h2><br />CHAPTER IV</h2>
+
+<h2>TRENCH WORK WITH THE BRITISH FORCES</h2>
+
+<p><br />Everyone seemed to know Tom, as he was heartily
+greeted on all sides. The appearance of the
+boys, however, was a puzzle to the group of aviators.</p>
+
+<p>"Let me introduce my friends, Ralph and Alfred,
+genuine American boys, who were with the
+Belgians in their great fight from Liege to Antwerp,"
+said Tom.</p>
+
+<p>"How did that happen?" asked one of the men,
+as he grasped their hands.</p>
+
+<p>"We were on the spot when war was declared,
+and we just pitched in and helped them out," replied
+Ralph.</p>
+
+<p>"Were you in any battles?" asked another.</p>
+
+<p>"Oh, in a dozen, or so," answered Alfred.</p>
+
+<p>"Good boys!" shouted several.</p>
+
+<p>"How did you happen to get here?" asked the
+first interrogator.</p>
+
+<p>"We came over with the Belgians, from Antwerp,"
+said Ralph.<span class="pagenum"><a name="Page_49" id="Page_49">[Pg 49]</a></span></p>
+
+<p>The foregoing information was enough to introduce
+the boys, and they were gratified to find several
+other Americans in the party.</p>
+
+<p>The reception was cut short by the peculiar antics
+of a huge Farman machine, which was approaching
+in an erratic manner. It seemed to dart
+back and forth, and swing around in short circles,
+as though wounded.</p>
+
+<p>"Something is the matter with Le Clere,"
+shouted Tom.</p>
+
+<p>At that moment the machine darted toward the
+earth, and the boys held their breaths at the anticipated
+calamity. Fifty feet from the earth the
+machine righted itself, and swooped upward,
+then, with a vicious plunge, it went down and
+struck the earth, the crash being plainly heard, although
+it landed more than five hundred feet from
+where they stood.</p>
+
+<p>Every one on the ground rushed toward the
+fallen aviator. Before they reached the scene, two
+men extricated themselves, and stood on the debris.</p>
+
+<p>"What was the matter?" asked Ralph.</p>
+
+<p>"Look at the holes in the wings," said Tom.
+"That tells the story; pretty well riddled."</p>
+
+<p>"Are you all right?" shouted one of the men.</p>
+
+<p>"Yes, but that was a dandy fight, and we
+brought him down," replied Le Clere, a daring
+Frenchman, who handled the machine gun.</p>
+
+<p>The Gnome motor was lying on the ground
+twenty feet from the wreckage. One of the planes
+was tilted up at an angle, and was uninjured, but<span class="pagenum"><a name="Page_50" id="Page_50">[Pg 50]</a></span>
+it carried the marks of twenty holes, through
+which the sunlight streamed.</p>
+
+<p>"That will give you an idea of the fascinating
+work we are engaged in," said Tom, pointing to
+the bullet marks. The body of the machine was
+wrecked, and the fuselage a mass of splinters. It
+was, indeed, a mystery how the two flyers escaped
+without injury.</p>
+
+<p>"What will they do with the machine?" asked
+Alfred.</p>
+
+<p>"They'll build up another out of it in two
+days," said Tom.</p>
+
+<p>"The Germans are marching west and south of
+Roubaix," said Le Clere. "They have already
+reached Mons, and are going straight toward
+Paris."</p>
+
+<p>The boys looked at each other in amazement.
+It seemed as though their trip to Paris would be
+interrupted, after all. Tom seemed to read their
+thoughts.</p>
+
+<p>"How far is it to Mons?" asked Alfred.</p>
+
+<p>"About fifty miles south," said Tom.</p>
+
+<p>"And what is the name of the town which we
+saw before we came down?" asked Ralph.</p>
+
+<p>"Lille," was the response. "But we must be
+going back," continued Tom. "We are going to
+move south in the morning, and I have a few
+things to pack up."</p>
+
+<p>After bidding good-bye to every one, they
+climbed into the airplane, and those present gave
+the boys a cheer, as the machine glided forward.
+Tom had promised to give them an hour's flight,<span class="pagenum"><a name="Page_51" id="Page_51">[Pg 51]</a></span>
+and it was now four o'clock. They had heard
+about taking observations, while on the grounds
+at Lille, and they busied themselves in trying to
+do work of that character. How small the houses
+were! They could see little creeping things, that
+soon evolved themselves into horses and wagons,
+but they seemed unreal.</p>
+
+<p>The flight to Lille covered a distance of forty-five
+miles, and it took them an hour. It didn't
+seem that they could have been aloft half of that
+time. Now, on returning, the novelty had worn
+off, and they were so much interested that they
+forgot to look at their watches until the deep blue
+haze, which betokened the approach to the sea,
+aroused them.</p>
+
+<p>"Why, it's past five o'clock," said Ralph.
+"Tom was going for an hour's flight only," said
+Alfred.</p>
+
+<p>"He just said that in fun, I suppose," replied
+Ralph.</p>
+
+<p>After alighting the boys did not know how to
+fully express their appreciation of Tom's kindness
+for the great treat, and they inquired whether
+they could not be of some service to him, as they
+were only too anxious to help him out in any way
+that would be useful.</p>
+
+<p>"Why, no; I don't know what I can put you at,"
+replied Tom. "Of course, there's always lots to
+do about the hangar, and the first thing to learn
+is how the machines are built, and how to handle
+them; and then, an important thing is to learn all
+the tricks in a gasoline engine."<span class="pagenum"><a name="Page_52" id="Page_52">[Pg 52]</a></span></p>
+
+<p>"That's just what we want to learn," said Alfred,
+enthusiastically.</p>
+
+<p>"But I thought you had to go to Paris to meet
+your father?" said Tom.</p>
+
+<p>"Yes," replied Alfred ruefully; "but we can
+come back. I'm sure there will be no objections."</p>
+
+<p>"Of course, it's your first duty to go to Paris&mdash;that
+is, if you can get there," said Tom, rather
+slyly.</p>
+
+<p>There was now nothing for them to do but to
+make an effort to reach Paris. Immediately after
+landing, they started for the tram way, and
+reached Dunkirk after six in the evening.</p>
+
+<p>"I never was as hungry in my life," said Ralph.</p>
+
+<p>"Do you know why?" answered Alfred.</p>
+
+<p>"Come to think of it, we didn't get anything to
+eat at noon," was Ralph's answer.</p>
+
+<p>After alighting from the cars, their first mission
+was to seek a restaurant, and from that point they
+soon reached the post office, only to be again disappointed.
+At the telegraph office they had the
+same bad luck.</p>
+
+<p>"I wonder where father is?" said Alfred.</p>
+
+<p>"I suppose we shall have to go, whether we
+want to or not," suggested Ralph. "Let us inquire
+at the transportation office."</p>
+
+<p>At the main office they soon learned that the
+troops from England were occupying every coach,
+motor wagon and bus that was in sight, and that
+there was no encouragement in that direction.
+But an idea occurred to Alfred.</p>
+
+<p>"We belong to the army, don't we?" he said.<span class="pagenum"><a name="Page_53" id="Page_53">[Pg 53]</a></span></p>
+
+<p>"Suppose we apply as soldiers, and tell them we
+must get to Paris at once."</p>
+
+<p>They reached the main office of the Army transportation
+service, and boldly made their way to
+the room indicated by an attendant. In a few moments
+they were ushered in, and saw at least a
+score or more soldiers and officers in the room, at
+one end of which sat a white-haired officer, and
+several other officers, issuing orders.</p>
+
+<p>"Your business?" said an officer, approaching
+them.</p>
+
+<p>"We have been with the Belgians, and have just
+come from Antwerp. We are Americans, and are
+trying to reach Paris, and we wanted to know if
+we couldn't go on one of the trains?" explained
+Alfred.</p>
+
+<p>The officer shook his head. "I am sorry to say
+that we cannot provide for any one unless connected
+with the army," he said.</p>
+
+<p>"But we are connected with the army," said
+Ralph. "We were messengers, and have had a
+lively time, too."</p>
+
+<p>"Yes, and we expect to join the flying corps, but
+father expects me in Paris," said Alfred.</p>
+
+<p>The officer smiled, and pondered a moment.
+Then, motioning to them, he passed out of the
+room, the boys following. They crossed the hall,
+and entered a narrow room.</p>
+
+<p>"Lieutenant," he said, "issue a permit for
+these boys to ride on any available train
+to Paris."</p>
+
+<p>The boys expressed their thanks to the officer,<span class="pagenum"><a name="Page_54" id="Page_54">[Pg 54]</a></span>
+and, after giving their names and home addresses,
+they received a card, which stated that the Army
+transport service permitted them to ride on any
+train where there was available room, at the discretion
+of the officer in charge of the train.</p>
+
+<p>"I should advise you to see the officer at the
+station in the morning, and get him to assign you
+to a train number, as the quickest way," said
+the clerk, as he handed them the permit.</p>
+
+<p>"Nothing like determination," said Ralph. "It
+is bound to pull you through."</p>
+
+<p>It was too late for them to return to the aviation
+field that evening, so after considerable
+search, they finally found a room, and after discussing
+the events of the day fell asleep, and
+awoke long after the sun had risen.</p>
+
+<p>"We've got to do some hustling," said Ralph.
+"We ought to see Tom this morning and tell him
+of our good luck."</p>
+
+<p>They partook of a hasty breakfast, and were at
+the station in order to get an assignment. But
+this was not an easy matter. They waited for
+nearly two hours before they were able to reach
+the proper official.</p>
+
+<p>"I am sorry to say that we cannot take you today,
+but I will try to make a reservation for you
+tomorrow. Come here after four this afternoon,"
+said the officer.</p>
+
+<p>"Now for the aviation field," said Alfred.</p>
+
+<p>They were detained for more than an hour
+watching several newly arrived regiments embark
+on a train, which slowly pulled out to the south,<span class="pagenum"><a name="Page_55" id="Page_55">[Pg 55]</a></span>
+and it was nearly noon when the grounds were
+reached. There seemed to be a change in the
+place. The hangars were empty, and no machines
+visible. A score of men were taking down the
+temporary hangars and from them it was learned
+that the entire corps had started at eight o'clock
+for the southern station.</p>
+
+<p>"That's too bad!" said Ralph regretfully. "I
+wish we had started back earlier."</p>
+
+<p>"Then we might go to the hospital," suggested
+Alfred.</p>
+
+<p>The head surgeon remembered the boys. "It's
+too bad," he said. "Lieutenant Winston has been
+removed to the hospital at Dunkirk, and will leave
+for England tomorrow; but his sister is still here,&mdash;ah,
+here she comes."</p>
+
+<p>"Oh, I am so glad to see you. Brother asked
+for you before he left. If you are going to England,
+you must go to see him. He is at Hempstead."</p>
+
+<p>"We expect to go to Paris tomorrow, and we
+are sorry not to be able to see him," Alfred
+told her.</p>
+
+<p>They at once returned to Dunkirk, and awaited
+anxiously until four o'clock. Before they had an
+opportunity to speak to the officer in charge, he
+shook his head, to indicate that there was no room.
+They lingered about, but it appeared to be a hopeless
+task. Four tracks ran by the station office,
+and these were constantly filled with empty cars,
+then loaded up, and drawn out. They watched the
+proceedings until the sun went down, when tired<span class="pagenum"><a name="Page_56" id="Page_56">[Pg 56]</a></span>
+and hungry, they crossed the street, entered a coffee
+house, and ate a hurried supper.</p>
+
+<p>As they were moving out the doorway, Ralph
+stopped. Turning to Alfred, he said: "We are
+chumps; that's about the size of it."</p>
+
+<p>"Why so?" asked Alfred.</p>
+
+<p>"We have the permits, haven't we? Why are
+we waiting for that fellow at the station to get us
+an assignment?" replied Ralph.</p>
+
+<p>"That's a fact; let's make our own assignment;
+come on," answered Alfred. "Is this train going
+south?" he asked, addressing a soldier who was
+about to enter a half-filled compartment.</p>
+
+<p>"Aw! I dare say it is," was the jolly response.</p>
+
+<p>"Get aboard," said Alfred.</p>
+
+<p>Unabashed, they swung themselves up on the
+running board, and entered the compartment.
+The occupants glanced at them for a moment, and
+seeing the trim uniforms, at once became inquisitive.</p>
+
+<p>"How did you happen to be directed to this
+train?" asked one of them.</p>
+
+<p>"Oh, we attended to that ourselves," said Alfred.</p>
+
+<p>"Our permit's all right, but we couldn't wait
+for them to make up their minds when we ought to
+go; so here we are," said Ralph, with a laugh.</p>
+
+<p>"Well, you fellows'll do; but it's a long way to
+Tipperary," said a voice, which trailed off into
+the tune of the well-known song. His companions
+chimed in, and it was not long before the occupants
+of the adjoining compartments joined in<span class="pagenum"><a name="Page_57" id="Page_57">[Pg 57]</a></span>
+the song. It was a jolly crowd, but no one seemed
+to know where they were going. All had heard
+of the rapid advance of the Germans toward Paris,
+and that General French was trying to impede
+their advance somewhere to the south.</p>
+
+<p>It was fully nine o'clock that night before the
+train made a real start. Before that time they
+were pushed around on the various sidings for
+an hour, and it was a relief to see the fields and
+feel the continual motion of the train as it finally
+speeded away.</p>
+
+<p>There was no time for talk now. Each tried
+to find a comfortable place in order to get some
+sleep. They dozed and dozed, as most people are
+liable to do in uncomfortable surroundings, and
+some hours afterwards an orderly appeared at the
+door, shouting:</p>
+
+<p>"All out, men; form in ranks."</p>
+
+<p>"I suppose we shall have to get out, too," said
+Alfred.</p>
+
+<p>"Why, no; this can't be Paris," replied Ralph.</p>
+
+<p>"I know bally well it isn't," said a voice.</p>
+
+<p>That settled it; tired and sleepy they swung off
+the running board, and looked at the long lines
+forming at the side of the train.</p>
+
+<p>"Do you know where we are?" asked Ralph, addressing
+a soldier at his side.</p>
+
+<p>"Don't know, my boy; we've had a steady run,
+though, for about three hours," was the reply.</p>
+
+<p>"We are east of St. Quentin; we passed
+through the city half an hour ago; this isn't much
+of a hill we are on, but the Germans and French<span class="pagenum"><a name="Page_58" id="Page_58">[Pg 58]</a></span>
+fought a battle on this very spot in the campaign
+of 1870-1," said an officer.</p>
+
+<p>Alfred saluted the officer, and asked: "How far
+are we from Paris, sir?"</p>
+
+<p>"I think it must be fully a hundred miles," was
+the reply.</p>
+
+<p>The men were ordered to line up, and soon the
+order came to march. As the boys had no other
+place to go, and the train was even then backing
+toward the city, they marched alongside of the
+column. The tramp was across open fields for a
+half-mile, where a road was sighted, but it was
+lined with troops, and heavy artillery, going eastwardly.</p>
+
+<p>The column continued on, parallel with the road.
+It was dry, dusty and warm. There was a hum
+of sounds, and occasionally a boom or two, which
+the boys recognized from their previous experiences.
+The most emphatic voices were those of
+the drivers, who were piloting the horses drawing
+the artillery and caissons. An hour's march
+brought them to a small stream, which was crossed
+without waiting for boats or hunting for bridges,
+as it was easily waded.</p>
+
+<p>Across the stream they ascended an elevation,
+at the crest of which was a line of soldiers busily
+at work with spades and pick-axes. Trenches
+were being formed. They were cheered by the
+workers, but there was no halting. On they went
+over level ground, only to meet another line of
+men similarly engaged. Several hundred feet beyond
+an order came like a shot: "Halt!"<span class="pagenum"><a name="Page_59" id="Page_59">[Pg 59]</a></span></p>
+
+<p>An orderly came riding up at full speed, and
+looked around. "We are waiting for orders, I
+suppose," remarked a lieutenant.</p>
+
+<p>The orderly put spurs to his horse, and rode
+to the right, as he espied a group of horsemen.
+"Form your men along this line, and dig in," he
+directed.</p>
+
+<p>The order was given: "File to the right; halt;
+stack arms."</p>
+
+<p>Several lorries, which had been following them,
+came up, and at a word of command the men began
+to unload shovels and picks. This began to look
+like business. It was now growing light, but it
+still lacked a half hour before sunrise.</p>
+
+<p>"Why can't we lend a hand?" inquired Ralph.</p>
+
+<p>"Of course we can," answered Alfred.</p>
+
+<p>They were alongside in an instant. Ralph
+jumped into the vehicle, and helped to hand out the
+implements, while Alfred tried to edge his way
+in. Their earnestness attracted the officer in
+charge, and he smiled, and nodded his head in approval.
+Thus two van loads were dumped out,
+and carried forward of the rows of stacked
+arms.</p>
+
+<p>An engineer officer marked out the line of the
+trench, and the men were set to work. They were
+now doing the job for a <i>real</i> purpose, as during
+their month of training in England these men had
+been instructed how to go about the business of
+making trenches, and it was wonderful to see how
+quickly the furrows were dug out. They were
+about four feet deep, the earth being thrown up<span class="pagenum"><a name="Page_60" id="Page_60">[Pg 60]</a></span>
+on the side toward the enemy, thus making a
+shelter trench five feet deep.</p>
+
+<p>As soon as the main line was thus completed,
+traverses were cut, leading out at right angle to
+the rear of the main trench. These were formed
+in zig-zag fashion, the object being to form shelter
+sections along the entire trench, so that those
+within would not be subjected to what is called an
+enfilading fire.</p>

+
+<h2><br />CHAPTER V</h2>
+
+<h2>ON THE FIRING LINE</h2>
+
+<p><br />"Look at the guns back there," shouted Ralph,
+as the company marched back to get their first
+breakfast after three hours of hard work.</p>
+
+<p>"Come on, boys!" said the corporal in charge,
+smiling at the boys. "You've worked pretty hard
+for lads of your age; come and have something to
+eat."</p>
+
+<p>"So we will," said Alfred; "but what are the
+guns doing back there?" he asked, as he pointed
+out a battery which had limbered up and was
+wheeling into position.</p>
+
+<p>"You will see in a few moments," replied the
+corporal, and before they reached the mess wagon
+the guns began to roar.</p>
+
+<p>"How far away are the Germans?" asked
+Ralph.</p>
+
+<p>"About two and a half miles, I should judge,"
+replied the corporal, looking at the battery.</p>
+
+<p>"How can you tell by looking at the guns?"
+asked Ralph.</p>
+
+<p>"By their angle," was the answer.</p>
+
+<p>Before they ceased speaking, the first shot was<span class="pagenum"><a name="Page_62" id="Page_62">[Pg 62]</a></span>
+fired, then another and another, all of them trial
+shots, as one of the soldiers explained. Then another
+battery to the left, heretofore unnoticed, began
+to fire, while one posted higher up on the right,
+and two more beyond, chimed in. This was a new
+experience to the boys, as the Belgians, with whom
+they had formerly associated, were lacking in field
+pieces compared with those they now saw and
+heard.</p>
+
+<p>The challenge was promptly accepted by the
+Germans, and within fifteen minutes the whole
+crest to the east of them, probably two miles distant,
+seemed to be ablaze. It was singular, however,
+that none of the missiles fell near the troops
+where the boys were located. On a little elevation
+to the right of the kitchen vans the boys noticed a
+group of officers with field glasses, intently scanning
+the rear of their position.</p>
+
+<p>"The blooming blokes are shooting too far," remarked
+a soldier.</p>
+
+<p>"Why are they doing that?" asked Alfred, who
+overheard him.</p>
+
+<p>"Oh, they'll get the range in time," he replied.</p>
+
+<p>"There's the first airship, to give them a
+pointer," said the corporal, as an airplane appeared
+in sight.</p>
+
+<p>"Two of our machines are coming up," shouted
+Ralph. "Now there'll be a fight."</p>
+
+<p>Ralph was right. The two English machines
+steered straight for the oncoming Fokker, the latter
+veering to the left in time to prevent too close
+a meeting. Within a minute three more German<span class="pagenum"><a name="Page_63" id="Page_63">[Pg 63]</a></span>
+machines came into sight, their appearance being
+answered by four of their own machines, which
+came up from the rear, and sailed straight across
+above them to the German positions on the crest
+of the hill. They were much higher than the German
+machines, the reason being that the enemy
+had a number of anti-airship guns to meet any
+flyers who dared to cross the line at a low altitude.</p>
+
+<p>It was, indeed, an interesting sight to observe
+the numerous airplanes, which were employed by
+the two forces. They seemed to be flying back and
+forth in the utmost confusion, and, frequently,
+puffs of smoke would indicate that they were firing
+at each other.</p>
+
+<p>The corporal with whom the boys talked seemed
+to be unusually well informed, and quite a number
+of the soldiers addressed him for information.</p>
+
+<p>"How do they recognize an enemy?" asked
+Ralph.</p>
+
+<p>"Oh, that's an easy matter," he replied. "I
+suppose the flyers in the air do it on the same
+principle that we are in the habit of recognizing
+automobiles. Why, I have a lad not ten years old
+who can tell the make of almost any auto the moment
+he sees it. Generally, if the make of the
+plane is similar to those attached to the aviator's
+side he is able to recognize it by the special mark
+it carries."</p>
+
+<p>"What mark do you mean?" asked Alfred.</p>
+
+<p>"Why, the English and the French mark is in<span class="pagenum"><a name="Page_64" id="Page_64">[Pg 64]</a></span>
+the form of a circle, generally three, each circle
+being of a different color," was the answer.</p>
+
+<p>"There is one,&mdash;why, it's red, white and blue,"
+said Ralph.</p>
+
+<p>"That's correct,&mdash;those are the colors of the
+Allies."</p>
+
+<p>"What are the German colors?" asked Ralph.</p>
+
+<div class="figcenter" style="width: 500px;">

+<span class="caption"><i>Allies&#39; Distinguishing Mark</i></span>
+</div>
+
+<p>"Black and white," said the corporal.</p>
+
+<p>"Oh, yes, they have a cross," said Alfred.</p>
+
+<p>"Yes; a cross in imitation of the iron cross, so
+far as its shape is concerned," he answered; "that
+is, a black cross on a white field."</p>
+
+<p>The company marched back to the line. During
+the next half hour there was nothing but expectancy,
+waiting, waiting,&mdash;that most trying
+thing for soldiers, who know that a battle is impending.
+Then a hundred feet to their rear there
+was a terrific explosion, which startled every one.<span class="pagenum"><a name="Page_65" id="Page_65">[Pg 65]</a></span>
+This was followed by others, but none reached
+the trench line.</p>
+
+<p>Thus, during the whole day, there was an exchange
+of artillery, the greatest damage being
+done to those in the rear who were trying to get
+to the front.</p>
+
+<p>"With the long range guns the great danger
+isn't always with the fellows in front," said the
+corporal.</p>
+
+<div class="figcenter" style="width: 500px;">
+<img src="images/illus061.jpg" width="500" height="276" alt="Black Cross on German Flyers" title="" />
+<span class="caption"><i>Black Cross on German Flyers</i></span>
+</div>
+
+<p>At four that afternoon the company was startled
+by an order to leave the trenches and fall to the
+rear. Every one cast questioning glances, but the
+knapsacks and rolls were quickly seized, and
+within ten minutes they were in line with the regiments
+to the right and the left. There was no
+hurrying or disorder.</p>
+
+<p>"I wonder why we are going back?" asked
+Ralph.</p>
+
+<p>"I suppose it's our business to retreat," returned
+the corporal.<span class="pagenum"><a name="Page_66" id="Page_66">[Pg 66]</a></span></p>
+
+<p>They marched fully a mile to the rear, passing
+on the way at least half a dozen lines of trenches,
+which had been thrown up since the boys covered
+the ground the night before. Every trench line
+was filled with soldiers, those in the front being
+the first to retire. On the way they saw how the
+great shells had played havoc with many of the
+works.</p>
+
+<p>They again crossed the river, and at six o'clock
+that night a new line was formed, and the spades
+and picks were again brought into use. The booming
+of cannon was incessant, and, although they
+tried to get some sleep after midnight, they were
+frequently aroused by the marching of troops.
+At daylight they were again marched out of the
+trenches, and a quarter of a mile from the last
+trench halted to partake of breakfast.</p>
+
+<p>The march was directly south, and at noon they
+reached a town of some importance, called
+Chauny. They went through without halting,
+crossed the river Oise, and at four o'clock halted
+on the eastern banks of a stream, which flowed
+northwardly. Here they waited for orders. A
+picturesque bridge spanned the stream, and the
+boys wandered across. West of the river was a
+broad expanse of country, perfectly level, and
+thousands of people from the nearby villages lined
+the road, all crossing to the west.</p>
+
+<p>All were excited, and seemed to be going toward
+the narrow road, which led to the left, and, naturally,
+the boys followed the movement of the
+crowd. Their curiosity was soon satisfied, for<span class="pagenum"><a name="Page_67" id="Page_67">[Pg 67]</a></span>
+beyond was a sight which caused their hearts to
+beat with joy. Fully a dozen airplanes were
+drawn up in line, and the boys started forward
+on a run that seemed to instill the same activity
+in many others present.</p>
+
+<p>"There's a Morane," said Ralph.</p>
+
+<p>"Yes; and that's Tom getting out of the machine,"
+shouted Alfred, as they rushed up and
+greeted Tom, who looked at them in astonishment.</p>
+
+<p>"And how did you get here?" he inquired.</p>
+
+<p>"Came over with the troops," explained Alfred.</p>
+
+<p>"With what troops?" he was asked.</p>
+
+<p>"Don't know," answered Ralph, "but they are
+from Essex."</p>
+
+<p>"Well, we've been on duty for a day directly
+over the lines east of St. Quentin," said Tom.</p>
+
+<p>"Did you have a fight?" asked Alfred.</p>
+
+<p>"I should say we did," answered Tom.
+"Brought down two, at any rate, and it was pretty
+hot for about an hour. So you are on your way
+to Paris; sorry you didn't get back before we
+started," he added.</p>
+
+<p>"We got to the grounds several hours after you
+left," said Alfred.</p>
+
+<p>"Glad you came; we can put you up, if you are
+willing," remarked Tom.</p>
+
+<p>"Thank you for the invitation; we helped them
+on the trenches and have done considerable marching,
+so it's better than going back to camp," said
+Ralph.</p>
+
+<p>The boys were up early in the morning, but<span class="pagenum"><a name="Page_68" id="Page_68">[Pg 68]</a></span>
+didn't have the least idea what steps to take to
+continue their journey. Everything in the way
+of transportation was reserved for the troops.
+Thousands of people were leaving their homes,
+and people with household effects, mounted on all
+sorts of conveyances, were noted on all sides, although
+at this time the Germans were not within
+ten miles of the river. The nearest railway to the
+south, which ran east and west along the southern
+bank of the river Aisne, was fully ten miles distant
+from this point.</p>
+
+<p>Tom was on hand early, and greeted the boys
+most affectionately.</p>
+
+<p>"I have been thinking I might be able to help
+you out a bit," he said, after a little talk. "We
+are ordered to the station near Villers-Cotterets,
+and that's only forty miles from Paris."</p>
+
+<p>"How can you help us?" inquired Ralph excitedly.</p>
+
+<p>"Probably I can give you a lift in the machine,"
+he said.</p>
+
+<p>"How far is that from here?" asked Alfred.</p>
+
+<p>"Twenty miles," replied Tom, and the two boys
+looked at each other hopefully, as he left them.</p>
+
+<p>Tom re-appeared at three o'clock, and informed
+them that they would start in fifteen minutes.</p>
+
+<p>"If you are ready for the trip, jump in and
+make yourselves comfortable," he said, and they
+required no second invitation.</p>
+
+<p>The dainty Morane just suited them, and they
+were in their seats in an instant. Tom then tossed
+them a light package, which they tucked away, and<span class="pagenum"><a name="Page_69" id="Page_69">[Pg 69]</a></span>
+the engine began to buzz. As they glanced around,
+two more machines seemed to vie with them in taking
+the air, then, as they again looked around, four
+more machines began to move, and soon all were
+on the wing, flying side by side, excepting two
+large Farman machines, which were well in the
+lead.</p>
+
+<p>Up, up, up, they went, the machines on line with
+each other maintaining a height of about four
+thousand feet, while the Farmans were about five
+hundred feet higher. Within a half hour they saw
+in the distance what appeared to be a silver ribbon
+running east and west, which proved to be the
+river Aisne, and to the east they saw the city of
+Soissons. The beautiful aviation ground was
+reached within an hour, and they alighted in front
+of a magnificent group of hangars in the center of
+well-tilled fields, so located as to afford a view in
+all directions from the grounds. The machine was
+then put up for the night, and Tom and the boys
+were glad to turn in for a much-needed rest.</p>
+
+<p>It was now the first day of September, and there
+had been nearly one month of war. The immense
+German forces had hewn their way through Belgium
+and entered France, reaching the cities of
+Laon, Epernay, and Chalons-sur-Marnek, thus
+forming a huge circle. They were within forty-five
+miles of Paris.</p>
+
+<p>When the boys awoke the next morning the first
+words that greeted them were: "The Germans
+are within five miles of Soissons."</p>
+
+<p>They rushed over to the hangar, but the machine<span class="pagenum"><a name="Page_70" id="Page_70">[Pg 70]</a></span>
+and Tom were not to be found. This was
+another source of grief to them, and they stared
+about, and wondered at this new turn of affairs
+until, meeting an attendant, Ralph inquired:</p>
+
+<p>"Do you know where the Morane has gone?"</p>
+
+<p>"They all started on a reconnoitering trip at
+five this morning," was the reply.</p>
+
+<p>"Do you think they will come back here?" asked
+Alfred.</p>
+
+<p>"That is doubtful," answered the man.</p>
+
+<p>"Then we shall have to make our way to Paris
+as best we can," said Ralph. "Do you think we
+would have any chances on the railroad?"</p>
+
+<p>"It's doubtful. I should take my chances over
+the highway directly south, if I wanted to make
+Paris," answered the man. Then, after a little
+reflection, he added: "A large English force is expected
+to be here from Laon, and it may arrive before
+noon. Possibly the flyers will return, but if
+the German forces are too close, they will go on
+to the next station at Crepy, directly south of this
+place."</p>
+
+<p>"Then that's the place for us," proposed Alfred,
+as he thanked their informant.</p>
+
+<p>They had no trouble in getting breakfast and
+after waiting for an hour, during which all sorts
+of rumors were floating about, they concluded that
+their only course would be to commence the trip.
+It was not necessary for them to inquire the way,
+as the highway, in the distance was filled with
+fugitives, all trying to get to Paris, or, at least,
+to avoid the invaders while there was yet time.<span class="pagenum"><a name="Page_71" id="Page_71">[Pg 71]</a></span></p>
+
+<p>Reaching the highway, they moved along with
+the procession, and, shortly before twelve o'clock,
+reached Crepy, ten miles from Soissons. They
+were now twenty-five miles from the center of
+Paris, and after getting a good meal they again
+took up the march over a beautiful road, which
+ran southeast.</p>

+
+<h2><br />CHAPTER VI</h2>
+
+<h2>VIGOROUS RED CROSS WORK</h2>
+
+<p><br />A mile from the town they came within sight
+of a cross road, filled with an immense concourse,
+which seemed to be wending its way east. Approaching
+nearer, they recognized troops, artillery
+and horsemen, the latter moving along in the
+fields parallel with the roadway.</p>
+
+<p>"It seems to me the firing is much nearer than
+when we started out this morning," said Ralph.</p>
+
+<p>As they passed through the marchers, and proceeded
+along the highway, they saw that troops
+were noticed posted everywhere, and that batteries
+were lying in wait in every advantageous spot.</p>
+
+<p>"I think we made a mistake in taking this road.
+We should have traveled the one which went to the
+west," said Ralph.</p>
+
+<p>"Then let's go out the first road that crosses
+this," replied Alfred.</p>
+
+<p>Meanwhile the sounds of battle came nearer and
+nearer. The artillery posted on the elevation began
+to speak, and before there was time to realize
+it the boys were within the battle zone, and bearing
+down on the road along which they were traveling.<span class="pagenum"><a name="Page_73" id="Page_73">[Pg 73]</a></span>
+They had no trouble, however, in leaving
+the road, as all the fences were down, and many
+of the fields were cut up with the hoofs of horses,
+and creased by the huge artillery wheels.</p>
+
+<p>To add to the confusion, shells began to fall all
+about them, and occasionally a terrific explosion
+would follow, leaving them dazed and startled.
+They ascended a hill, and, looking back, saw nothing
+but dense clouds of smoke, and a scene of indescribable
+confusion.</p>
+
+<p>"What's that down there?" shouted Alfred,
+pointing to a group of vans close by the side of a
+stream.</p>
+
+<p>"That must be a Red Cross station; so it is,"
+said Ralph.</p>
+
+<p>Their footsteps were hurried, but before the
+place was reached they saw stretcher bearers, and
+also noticed the wounded being unloaded from a
+field van. Glancing to the left they saw fully a
+dozen vans of like character, as indicated by the
+great red crosses on their sides, rushing up the
+narrow street from the southeast.</p>
+
+<p>"Let's give them a hand," said Alfred.</p>
+
+<p>A business-looking surgeon stood at the rear
+end of one of the vans, as the boys approached.
+They saluted. "Can we do anything to help out?"
+asked Ralph.</p>
+
+<p>The doctor looked at them for a moment, apparently
+non-plussed at their appearance.</p>
+
+<p>"Yes, indeed; we need you and many more willing
+ones like you."</p>
+
+<p>"What shall we do?" asked Alfred.<span class="pagenum"><a name="Page_74" id="Page_74">[Pg 74]</a></span></p>
+
+<p>The surgeon drew a pad from his pocket, wrote
+a few words on it, handed it to the boys, and said:
+"Present this to the officer yonder."</p>
+
+<p>The officer indicated received the slip, while directing
+the disposition of a wounded soldier,
+glanced at it hurriedly, then looked at the boys.
+"Ah, want to get on duty? We can accommodate
+you; there, put those stretchers in the van. One
+of you can take this to the supply van," he said.
+Ralph seized the paper, and looked about.</p>
+
+<p>"The van with the flag on it," explained the officer.</p>
+
+<p>Ralph rushed across the intervening space, and
+presented the paper to a Red Cross nurse, who
+smiled sweetly as she glanced at the paper, and
+looked inquiringly at Ralph. She then turned,
+seized three packages, and handed them to Ralph,
+while he thanked her and quickly rushed away.
+The packages were stored in the van, water was
+supplied to the containers in the vehicle, and the
+moment the last article was on board, the van
+started.</p>
+
+<p>The boys were both within, as well as three men
+and a surgeon. They had heard no orders, but
+knew they were bound for the battlefield. There
+was no talking indulged in. The men were too
+intently engaged in listening to the din of the
+conflict, and watching the soldiers moving to and
+fro.</p>
+
+<p>"Has there been much of a fight?" asked Ralph.</p>
+
+<p>"They have been at it all morning," said one
+of the men. Then, glancing at the boys, he continued:<span class="pagenum"><a name="Page_75" id="Page_75">[Pg 75]</a></span>
+"But this is a bad place for you youngsters."</p>
+
+<p>"I am afraid you will regret it before you return.
+The scenes are awful," continued the man.</p>
+
+<p>"We know what it is," said Alfred. "We saw
+the worst kind of fighting in Belgium."</p>
+
+<div class="figcenter" style="width: 600px;">
+<img src="images/illus071.jpg" width="600" height="316" alt="French and German Flags" title="" />
+</div>
+
+<p>"We were with the English in the battle east of
+Soissons, and had some experience there," said
+Ralph.</p>
+
+<p>"Aren't you English?" asked the surgeon.</p>
+
+<p>"Oh, no; we're Americans," replied Alfred.</p>
+
+<p>At this point a lieutenant rode up alongside, and
+shouted: "There has been a tough scrap at the
+mill; we have driven the Germans back; take this
+road down to the river; you will find plenty of
+poor fellows there who will need you."</p>
+
+<p>The French had made a terrific charge at this
+point, and many were lying dead, where the van
+slowed down, so as to give the surgeon and helpers
+an opportunity to pick out the wounded cases.<span class="pagenum"><a name="Page_76" id="Page_76">[Pg 76]</a></span></p>
+
+<p>Wherever there was a movement in a prone figure
+the men stopped and made an examination. In
+some cases the wounds were hurriedly dressed,
+and the victim's position rendered comfortable.
+In other cases the surgeon motioned to the helpers,
+who quickly brought the stretchers, and carried
+the wounded into the van.</p>
+
+<p>On this single trip they attended, or gave first
+aid to thirty, but only the most severely injured
+were taken into the van, which now turned and
+quickly speeded along the narrow road to the field
+hospital. Reaching this station the men were carefully
+taken out, their wounds re-examined, and
+carried into a temporary shelter for a second operation
+or treatment.</p>
+
+<p>A huge van then arrived from the southwest.
+Carefully and tenderly eight men were placed on
+the cots within, the boys being delegated to assist.
+When the order was given to leave, the boys
+remained in the van, as it started out on its journey,
+but they didn't have the least idea where it
+was bound, although you may be sure they were
+curious to know.</p>
+
+<p>After every one had settled down,&mdash;that is, if
+such a thing as quiet and comfort were possible
+in a van load of wounded men, Ralph turned to
+the surgeon, and said. "Where are we going?"</p>
+
+<p>"To Paris, if we can get through," was the reply.</p>
+
+<p>The van had a wonderful set of springs, so that,
+although it was necessary hour after hour to go
+through fields, instead of traveling along the road,<span class="pagenum"><a name="Page_77" id="Page_77">[Pg 77]</a></span>
+there was little discomfort to the wounded men.</p>
+
+<p>"Why are the men being taken to Paris?" asked
+Alfred.</p>
+
+<p>"So as to relieve the emergency station behind
+the battle front," explained the surgeon. "That
+is one thing; the other is, that the great German
+forces are driving in our comparatively small
+army, until the Paris forts are reached. There
+they will be stopped, and we must take our
+wounded with us, and out of the reach of the enemy."</p>
+
+<p>At Dammartin they saw the first Red Cross railway
+van,&mdash;an entire train load, filled with wounded
+from the emergency stations, and here also they
+were joined by fifteen vans taking the wounded on
+to the city. It was thus a fortunate stroke for the
+boys that they undertook to help the field hospital
+workers, for it directly assisted them in their effort
+to reach the end of their journey.</p>
+
+<p>Traveling was slow, and many detours were
+necessary, so it was not until the fourth day of
+September that they caught sight of the walls of
+Paris, and they soon had the pleasure of driving
+over the beautiful smooth streets again. They
+went directly to the center of the city, passed down
+the rue de l'Op&eacute;ra, through the Place de la Concorde,
+and over the bridge to a hospital near the
+Place des Invalides.</p>
+
+<p>Their charges in the van were soon provided
+for, and carried into comfortable berths. As they
+were leaving the ward, they heard a weak voice
+calling: "Ralph; Alfred."<span class="pagenum"><a name="Page_78" id="Page_78">[Pg 78]</a></span></p>
+
+<p>They were startled, and turned around with
+wondering glances. A nurse motioned to them,
+and pointed toward a figure with bandaged head
+and arms. They approached.</p>
+
+<p>"You don't know me, I suppose?" said the
+voice.</p>
+
+<p>"No,&mdash;no," said Ralph.</p>
+
+<p>"I believe it's Tom," said Alfred.</p>
+
+<p>"Right," said the voice.</p>
+
+<p>The boys knelt down at his side at once. "How
+did it happen?" asked Alfred.</p>
+
+<p>"Well, they got me first; but I brought down
+two of them before I was hit," Tom told them.</p>
+
+<p>"What became of the machine?" was Alfred's
+next question.</p>
+
+<p>"I don't remember anything about it," was the
+reply, "but they told me it made fine kindling
+wood."</p>
+
+<p>"Too bad!" consoled Alfred. "I liked that little
+Morane; and to think it's all broken up."</p>
+
+<p>"How did you get here?" asked Tom.</p>
+
+<p>"Why, we came down with the Red Cross people,"
+explained Ralph.</p>
+
+<p>"You seem to get into all sorts of trouble, all
+along the line," said Tom with an attempt to
+laugh.</p>
+
+<p>"But are you badly hurt?" inquired Alfred
+anxiously.</p>
+
+<p>"The doctors say that there are only a few
+bones broken, several joints wrenched out of
+shape, and some of the bark peeled off, but I ought
+to be out in a few weeks," said Tom.<span class="pagenum"><a name="Page_79" id="Page_79">[Pg 79]</a></span></p>
+
+<p>"Tell us what we ought to do now?" Alfred
+asked him.</p>
+
+<p>"What do you mean?"</p>
+
+<p>"Why, I want to know whether they will expect
+us to keep on in the Red Cross service?"</p>
+
+<p>"You volunteered, didn't you?" replied Tom.
+"You helped them out of your free will, and you
+can leave whenever you want to, if that's what you
+are getting at."</p>
+
+<p>"I wouldn't mind volunteering in the aviation
+corps," said Ralph. "I would just like&mdash;&mdash;"</p>
+
+<p>"So they got you this time, eh?" said a voice.</p>
+
+<p>The boys turned, and saw a handsome man with
+the uniform of a lieutenant in the aviation service,
+who approached, and leaned over Tom. Tom
+replied with a smile, and raising his injured hand,
+pointed to the boys.</p>
+
+<p>"Lieutenant," he said, "I want you to get acquainted
+with two of my American friends, who
+have been in the thick of it right from the start.
+Now you'll be conferring a special favor if you
+can take them in to help you out. Oh, they're
+bricks," continued Tom, as he saw a shade of discouragement
+in the lieutenant's features, "they
+are made of the right stuff."</p>
+
+<p>"We leave for Verdun in the morning," said the
+lieutenant, "but I will see what can be done in the
+meantime."</p>
+
+<p>As they left the hospital the first thought was
+to go to the Continental Hotel to try to get a trace
+of Alfred's father. Arriving there a letter was
+handed them, together with two telegrams from<span class="pagenum"><a name="Page_80" id="Page_80">[Pg 80]</a></span>
+Berne, Switzerland, one of the messages having
+been received that very day. The missives informed
+him that his father had not been able to
+leave German territory until the twenty-eighth of
+August, and as he had received word that the Germans
+were approaching Paris he thought it unwise
+to make the trip to that point, but would
+await word from them before deciding what to do.</p>
+
+<p>"How far is it from Berne to Verdun?" Alfred
+asked the clerk.</p>
+
+<p>"About three hundred kilometers," was the reply.</p>
+
+<p>"Let's see; that's about two hundred miles,"
+said Alfred. "And it's a hundred and fifty miles
+to Verdun.</p>
+
+<p>"Then we'll go to Verdun," said Ralph. "But
+how?"</p>
+
+<p>The subject was debated for an hour, when it
+was decided to return to the hospital. They had
+forgotten to learn the lieutenant's name, although
+probably Tom knew how to reach him, they reasoned.</p>
+
+<p>Arriving at the hospital they learned that Tom
+was asleep, and that no one would be permitted
+to see him, so they wandered around without the
+slightest idea what course to pursue. They even
+discussed the feasibility of walking to Verdun, but
+that idea was soon abandoned.</p>
+
+<p>"I wonder where the aviation grounds are?"
+remarked Ralph.</p>
+
+<p>They soon learned that several corps were located
+at the great race course in the Bois de Boulogne,<span class="pagenum"><a name="Page_81" id="Page_81">[Pg 81]</a></span>
+and they were soon on the underground
+railway speeding to the nearest station in that
+vicinity. Arriving at the grounds they approached
+the entrance, and their hearts sank as
+they saw a great crowd gathered, and one after
+the other turned away.</p>
+
+<p>"Chances of getting in seem to be pretty slim,"
+said Alfred.</p>
+
+<p>"Well, we might try it, anyhow," said Ralph,
+as he pushed forward.</p>
+
+<p>They marched up to the gate, and passed
+through without the least objection on the part
+of the guards. This was the greatest surprise to
+both. They had forgotten that the uniforms they
+wore gave them admittance without question.
+Evidently they were taken for army messengers.</p>
+
+<p>"See that American flag?" shouted Ralph.</p>
+
+<p>"That's the place for us," replied Alfred.</p>
+
+<p>Accordingly, they lost no time in making for the
+hangar on which the emblem appeared. They saw
+a Farman machine partly outside of the hangar,
+and in the body of it was seated a ruddy-faced
+chap.</p>
+
+<p>"What's up?" he asked.</p>
+
+<p>"Came over to help you out," said Alfred.</p>
+
+<p>He looked down, and slowly said: "You did,
+eh?"</p>
+
+<p>"Well, we've seen a little active service at the
+front, so far," explained Ralph, "been in battle
+several times, have been captured by the Germans,
+helped to build trenches, worked with the Red
+Cross people, and had a few flights in an airplane,<span class="pagenum"><a name="Page_82" id="Page_82">[Pg 82]</a></span>
+and as we like aviation business best of all,
+we thought we'd come over and go to work."</p>
+
+<p>The airman raised himself, sat down on the
+side of the car body, and commenced to laugh, although
+Ralph's remark was said without the least
+tinge of pride or boasting. Several from the adjoining
+hangars came in to learn the cause of the
+boisterous mirth.</p>
+
+<p>"Well, that's fresh enough to come from real
+American boys," he said, after he had sobered
+down a little.</p>
+
+<p>"That's right; we're from the United States;
+we came here because we saw the flag on the outside;
+what shall we do the first thing?" said Alfred.</p>
+
+<p>"From America?" said the man, climbing down
+from the machine. "And you are regular Yankees?
+Well, well; that's too good! I'm something
+of an American myself. By jingo, you're
+the kind of fellows to have around. Want a job?
+Where did you get your uniforms? They look all
+right."</p>
+
+<p>"Oh, these are Belgian uniforms. We were
+with them, you know, and had a pretty hot time,
+too," said Ralph.</p>
+
+<p>This information, as they now knew, was the
+best credential possible, and they were soon the
+center of an admiring crowd. Somehow the determined
+matter of fact and positive way which
+the boys adopted had the effect of winning their
+way, and it was thus that they had the satisfaction
+of entering a service which it is a most difficult<span class="pagenum"><a name="Page_83" id="Page_83">[Pg 83]</a></span>
+thing to do even with the best credentials.</p>
+
+<p>The happiness of the boys was complete when
+their new friend told them to get up on the machine,
+and help him to take out the engine. Coats
+came off in a hurry, and they looked around for
+some substitute to protect their clothing.</p>
+
+<p>Their friend supplied the necessary articles at
+once remarking as he did so that he ought to know
+their names.</p>
+
+<p>After this information was supplied, he remarked:
+"My name is Martin; Bill Martin, Fifth
+Aviation Corps; don't forget the Corps or you
+may have trouble in getting into the grounds;
+and, by the way, how did you happen to get
+through?"</p>
+
+<p>"If you mean the gates, why, we just walked
+right through," said Alfred.</p>
+
+<p>"Just as though you had a right to do so!" said
+Martin, as he again commenced to laugh. "You
+said you were up in an airplane; where was that?"</p>
+
+<p>"Up at Dunkirk, and back of the firing line,
+south of the St. Quentin," said Ralph.</p>
+
+<p>"Do you know Tom Watkins?" asked Alfred.</p>
+
+<p>"Do I know Tom? Why, we came over together;
+poor fellow, he got a bad fall," said Martin.</p>
+
+<p>"We heard about it and saw him at the hospital
+today," said Alfred.</p>
+
+<p>"You don't say? So you've been flying with
+Tom? I'm glad to know that," said Martin, as
+he nodded his head approvingly.</p>

+
+<h2><br />CHAPTER VII</h2>
+
+<h2>BOUND FOR VERDUN</h2>
+
+<p><br />For three days more the boys wandered about
+Paris,&mdash;three days of the most fearful suspense;
+and then began the battle of the Marne. Every
+airplane in and about Paris was at the front, on
+the line somewhere, and the boys were deprived
+of the opportunity to see the new friend they had
+made at the Bois de Boulogne station.</p>
+
+<p>They were so sure of being able to go to Verdun
+that Albert wrote to his father of their plans,
+in the hope that he would consider it wise to leave
+Switzerland for that point, where they might meet.</p>
+
+<p>The Germans had been defeated; Paris was
+safe, the French line having held firmly all the
+way to Verdun. The determination to go there
+was firmly fixed in their minds, but they could see
+no way to accomplish the purpose. A visit to
+Tom at the hospital only resulted in their being
+told that the lieutenant was in the field, no one
+knew where.</p>
+
+<p>"I have an idea," said Ralph, as they emerged
+from their room one morning.</p>
+
+<p>"What is it?" asked Alfred.</p>
+
+<p>"We might get attached to the Red Cross some<span class="pagenum"><a name="Page_85" id="Page_85">[Pg 85]</a></span>
+way, and that would be sure to take us to the
+front," replied Ralph.</p>
+
+<p>"That would be just as hard as to get in with
+the flying people," answered Alfred.</p>
+
+<p>"That may be so, too, but I can't see any other
+way."</p>
+
+<p>They again called at the Continental Hotel in
+the hope that there might be some further news.
+To their surprise they found a letter from Alfred's
+father with a check for their personal expenses.
+While reading the letter they overheard
+a conversation which gave them the solution, as
+they thought, of their difficulties.</p>
+
+<p>"No," said a voice, "they will not ticket us to
+any point near the firing line, but we might go to
+St. Dizier, and from there work our way north."</p>
+
+<p>"Good idea; let's book at once," said the second
+voice.</p>
+
+<p>"Come on," said Alfred. "That's the right
+tip. Let's find out where St. Dizier is."</p>
+
+<p>The clerk informed them: "It is about a hundred
+and sixty miles east of Paris."</p>
+
+<p>"Then it can't be far from Verdun," remarked
+Alfred.</p>
+
+<p>"Sixty miles southwest, I should judge," was
+the answer.</p>
+
+<p>"Do you think we would have any trouble in
+reaching that point?" asked Ralph.</p>
+
+<p>"I think the trains are still running, but they
+may not adhere to the regular schedule. The line
+runs south of the war zone, you know," said the
+clerk.<span class="pagenum"><a name="Page_86" id="Page_86">[Pg 86]</a></span></p>
+
+<p>That settled it. They hurried to the Banque
+Fran&ccedil;aise, and having secured currency for the
+check, started for the booking office as fast as
+they could walk. It was impossible at this time
+to get a conveyance as only the underground railways
+and a few tram cars were in service, the
+government having requisitioned all the horses,
+and automobiles a week previous to this time.</p>
+
+<p>They booked second class, the official stating
+that the tickets were sold at the risk of the holders,
+and that they would have to take their chances
+on the trains, so they were at the eastern railway
+station before one o'clock, in the hope that the
+regular through train at two that day would be
+able to accommodate them. In this they were disappointed,
+so they waited about until five o'clock,
+and had the good fortune to have the tickets accepted
+by the gateman.</p>
+
+<p>They passed through an immense crowd of
+newly arrived soldiers, and were jostled about by
+hosts of men, women and children who were departing
+for the southeast, most of them bound
+for Chaumont. Within an hour they finally found
+a train bound for their destination, but it was another
+hour before the train began to move.</p>
+
+<p>The trip was a weary one all through the night,
+as they seemed to stop at every station, although
+it was the fast express. The intense excitement
+of the people all along the line; the passing of
+trains; the crying out of the latest news; and the
+bustle of the new arrivals in the already crowded
+compartments, made sleep impossible. The sun<span class="pagenum"><a name="Page_87" id="Page_87">[Pg 87]</a></span>
+had been up two hours before the station of St.
+Dizier was announced.</p>
+
+<p>The boys were out and scampering along the
+platform ahead of most of the crowd. As they
+passed out the end of the station they noticed a
+sign on a train: "For Bar-le-Duc, 10 o'clock."</p>
+
+<p>"Let's see where that place is," said Alfred.</p>
+
+<p>The information was obtained. It was twenty
+kilometers northeast.</p>
+
+<p>"That's the place we must go; it's twenty miles
+toward Verdun, and now is our time," said Ralph.</p>
+
+<p>"Let's have something to eat first," said Alfred.</p>
+
+<p>After the meal they booked for Bar-le-Duc, and
+this train started promptly. Only two coaches
+were reserved for civilians, the others being filled
+with soldiers. The town, which was reached
+shortly before noon, had the appearance of an
+armed camp. Here they received the startling
+news that the Germans were at St. Mihiel, thirty-five
+miles northeast of that place.</p>
+
+<p>There was no sign of panic there, however.
+Verdun, Toul and Nancy were still intact, and
+there was no fear that either place would
+yield.</p>
+
+<p>Before they had been in the city an hour they
+saw a dozen or more airplanes overhead, and it
+was not long thereafter until they learned that
+one of the most famous stations belonging to the
+flyers was located north of the place. A conveyance
+was readily obtained, as a line of busses paralleled
+the railway track, and in another hour they<span class="pagenum"><a name="Page_88" id="Page_88">[Pg 88]</a></span>
+were on the plateau where the great hangars were
+located.</p>
+
+<p>As they were crossing the field, and approaching
+the first tier of hangars the boys noticed the
+two men whose conversation had been overheard
+in the Continental hotel. "They are the very
+men," said Alfred; "I wonder what they are here
+for?"</p>
+
+<p>The men stopped and looked at the boys for an
+instant. Ralph approached them and said, with
+a smile: "You beat us here after all."</p>
+
+<p>The men appeared to be puzzled at being thus
+addressed. Alfred saw that they did not understand
+Ralph's greeting, and said: "We are under
+obligations to you for telling us how to get here,
+and I want to thank you."</p>
+
+<p>"I don't exactly understand," said one of the
+men.</p>
+
+<p>"We heard you talking about making this trip,
+and as we wanted to get to the front without knowing
+just how to do it, your conversation helped us
+out," said Ralph.</p>
+
+<p>"I'll bet you're American boys," said one of
+them, laughing.</p>
+
+<p>"Indeed, we are," said Alfred.</p>
+
+<p>"Belong to the service?" asked the other.</p>
+
+<p>"Oh, yes," answered Ralph,&mdash;"that is, we did
+belong to it."</p>
+
+<p>"Which branch?" asked the man.</p>
+
+<p>"Messenger service in Belgium, aviation and
+trench service with the English, and Red Cross
+in the French army," answered Alfred.<span class="pagenum"><a name="Page_89" id="Page_89">[Pg 89]</a></span></p>
+
+<p>This response was answered by hearty laughter
+on the part of both men, and one of them responded:
+"That is a pretty comprehensive service,
+I should say."</p>
+
+<p>"Where are you from?" asked the other.</p>
+
+<p>"New York," answered Ralph. "Why, you
+look like Americans, too."</p>
+
+<p>"We're from the same place," was the answer.</p>
+
+<p>"And you look like newspaper men," remarked
+Alfred.</p>
+
+<p>"That's a good guess," was the reply. "But
+how did you know?" he asked.</p>
+
+<p>"I saw you taking notes as we walked across
+the field," answered Alfred.</p>
+
+<p>"Good inference," he replied. "Are you looking
+for a job?"</p>
+
+<p>"Yes, we're going into the aviation service,"
+answered Ralph, with all the assurance of a winner.</p>
+
+<p>"See you again," was the final reply, as the two
+men left them.</p>
+
+<p>"Now, I wonder if they have any American flags
+at this place?" remarked Ralph.</p>
+
+<p>They marched back and forth without a sign
+of that much desired emblem. At one of the hangars
+two men were tugging at a machine, and
+slowly bringing it out of the hangar. Without a
+word the boys sprang forward and assisted in the
+operation, an act which brought thanks from the
+men. Then, more in curiosity than anything else,
+they slowly walked around the machine and examined
+its construction.<span class="pagenum"><a name="Page_90" id="Page_90">[Pg 90]</a></span></p>
+
+<p>The aviator watched them for a few moments.
+Evidently, to his mind, the boys knew all about
+flying machines, or, at least, must have had some
+acquaintance with them. This seemed to interest
+him, and he began a conversation with them. He
+soon learned their history, and bestowed words of
+praise on them for what they had done.</p>
+
+<p>"So you want to be aviators, eh?" he inquired.</p>
+
+<p>"Yes, and we'll do anything to get in," said
+Alfred.</p>
+
+<p>"To be aviators in the service of the Government
+it will be necessary to take the Regulation
+course," said the man.</p>
+
+<p>"There isn't time for that," said Ralph. "We
+can help out now, even if we don't do any flying,
+can't we?"</p>
+
+<p>The man chuckled. "I suppose you can tighten
+up bolts, examine, and stretch the stay wires, and
+things like that?" he remarked.</p>
+
+<p>"As well as take out the engine and overhaul
+it," added Ralph.</p>
+
+<p>"Well, yes; that's a pretty good job; do you
+think you could do that?" he asked.</p>
+
+<p>"Why, yes; we know something about it," replied
+Ralph.</p>
+
+<p>"Well, stay around here; we want some handy
+fellows; but I'm afraid you'll have a hard job
+to get on the pay roll," he added.</p>
+
+<p>"Never mind about that end of it; we want to
+be doing something; that's the main thing," said
+Alfred.</p>
+
+<p>It would not be interesting to go through the<span class="pagenum"><a name="Page_91" id="Page_91">[Pg 91]</a></span>
+long details of work that the boys entered into
+under those circumstances. Each day for more
+than two months the boys found plenty of work to
+do. They became general favorites at the camp,
+and while their services were not recognized in an
+official way, as the regulations did not permit of
+the employment of minors, still, in view of the fact
+that they had such an interesting history, and had
+entered into the work with such zest the commandant
+at the station permitted them to remain, and
+eventually provided them with rations and quarters,
+to which was added a small pay, such as attached
+to those in the messenger service.</p>
+
+<p>During this period the boys had many opportunities
+to go aloft on practice drills, and on more
+than one occasion they had the privilege of operating
+the machines while in flight, accompanied, of
+course, by the regular pilots. Attached to the station
+were a half-dozen machines used for the purpose
+of teaching control, and to enable pupils to
+become familiar with the handling of the machines.
+They were designed merely to skim the ground,
+the power being so limited that they could not be
+raised from the ground except for very short
+glides. These the boys frequently used, and the
+experienced aviators were greatly pleased at their
+wonderful progress. It was a strict rule, however,
+that none but regularly licensed aviators should
+pilot the government machines, and that prohibited
+them from handling the machines on regular
+service.</p>
+
+<p>It was during the second week of the third<span class="pagenum"><a name="Page_92" id="Page_92">[Pg 92]</a></span>
+month that the boys had the first opportunity of
+showing their capabilities. During a trial flight
+with sub-lieutenant Guyon, while at an altitude
+of five thousand feet, Ralph noticed the machine
+dart downwardly, and, glancing back, saw Guyon's
+head fall forward, and his hand drop from the
+lever.</p>
+
+<p>Without waiting to inform Alfred he crawled
+out of the pit, and seizing the control lever,
+pushed it back in time to bring the ship to an even
+keel. Alfred saw the motion, and followed Ralph.
+Together they succeeded in drawing the pilot to
+one side, thus enabling Ralph to let himself down
+into the position which enabled him to handle the
+lateral controls, that were operated by the
+feet.</p>
+
+<p>With Ralph thus fully in control of the machine,
+Alfred turned his attention to poor Guyon,
+who tried to raise his head, and occasionally
+gasped, as though trying to recover his breath. It
+was not until the machine was nearing the earth
+that he opened his eyes, and seemed to realize his
+position, but he was too weak to give any instructions
+or render assistance.</p>
+
+<p>Ralph made a good landing, and the moment
+the machine ceased to move Alfred jumped from
+it, and ran to the office of the surgeon.</p>
+
+<p>"Something is the matter with the lieutenant!"
+he cried, as he entered the door.</p>
+
+<p>"What is the trouble? Where is he?" asked the
+surgeon, as he moved out of the door in response
+to Alfred's appeal.<span class="pagenum"><a name="Page_93" id="Page_93">[Pg 93]</a></span></p>
+
+<p>"He was taken sick while we were in the air,"
+said Alfred.</p>
+
+<p>"And how did you happen to get down safely?"
+asked the surgeon.</p>
+
+<p>"We took charge of the machine," replied Alfred.</p>
+
+<p>"Who are <i>we</i>?" he asked.</p>
+
+<p>"Ralph and myself; we were up with him."</p>
+
+<p>The lieutenant was being taken from the machine
+when the surgeon arrived. Restoratives
+were at once applied, and within a half hour the
+attack seemed to wear itself away, and he began
+to show a normal color.</p>
+
+<p>His eyes rested on Alfred when he awoke from
+the first quiet nap, and raising his hand approvingly
+said: "That was a good job, Alfred; couldn't
+have been better."</p>
+
+<p>"What do you mean?" asked Alfred.</p>
+
+<p>"You brought us down all right, I mean," he
+replied.</p>
+
+<p>"Oh, Ralph did that," was the reply of Alfred.</p>
+
+<p>"Well, no matter; you fellows didn't get rattled;
+that's the main thing," said the lieutenant.</p>
+
+<p>An incident of this kind could not remain a
+secret long in a camp of this character. The Commandant
+took particular occasion to commend
+them for their performance, and it was a long step
+in their favor when the corps moved to the north
+to take its place in the great aviation camp directly
+south of Verdun.</p>

+<h2><br />CHAPTER VIII</h2>
+
+<h2>AN AEROPLANE AMIDST THE LIGHTNINGS</h2>
+
+<p><br />Two days after the occurrence related in the
+preceding chapter, the first section of the Corps
+was ordered to proceed to the Verdun station.
+Lieutenant Guyon belonged to this part of the
+force, and, as he had now recovered, was instrumental
+in securing the assignment of the boys to
+his care.</p>
+
+<p>"Then we can go along?" asked Ralph, with
+some doubts and misgivings, as they were packing
+the belongings of the lieutenant.</p>
+
+<p>"I have arranged that," said the lieutenant.</p>
+
+<p>"What is that?" asked Alfred, who appeared at
+the door of the hangar.</p>
+
+<p>"We are going," shouted Ralph.</p>
+
+<p>"Yes; you might as well get your things packed
+and put them in the machine," said the lieutenant.</p>
+
+<p>The boys laughed, for outside of a few trinkets,
+and underclothing, they had nothing of importance
+to take along. They remarked that it was singular
+how few things seemed to be really needed,
+traveling, as they did, from place to place at a
+moment's notice.<span class="pagenum"><a name="Page_95" id="Page_95">[Pg 95]</a></span></p>
+
+<p>"When do you intend to start?" asked Ralph.</p>
+
+<p>"Whenever we are ready," was the reply.
+"We intend to leave in squadron formation and
+manoeuver for an hour, and afterwards each is
+to make for the station on his own hook."</p>
+
+<p>Shortly thereafter the first signal was given.
+The machine was pushed out and lined up. At the
+second signal the machines were mounted. At the
+third tap the motors began to hum, and soon there
+was a movement in the whole line. It was a splendid
+spectacle, as the machines left the ground, and
+rose majestically toward the west, the direction
+from which the wind was blowing.</p>
+
+<p>The manoeuvers were particularly interesting
+to the boys, and the lieutenant led his section in
+the formation during the entire practice until the
+captain's flag on the great Duperdessun indicated
+that the machines were free. After making a
+great sweep to the west the lieutenant turned to
+the left, encircling the town, and pointed due
+east.</p>
+
+<p>Before they had proceeded fifteen kilometers,
+something happened to the engine, for it ceased to
+hum. They were then at an altitude of a mile, and
+inability to start the motor made it necessary for
+them to volplane to the earth. Sighting a considerable
+town to the left, which was located south of
+a canal, the machine was directed toward a
+smooth, open field, not far from the environs, and
+after landing they learned that the place was Ligny-en-Barrois.</p>
+
+<p>It was found that through some accident the<span class="pagenum"><a name="Page_96" id="Page_96">[Pg 96]</a></span>
+petrol tank had started a leak, and that the liquid
+was slowly oozing out during the flight, without
+giving the first indication until the engines failed.
+It was just the kind of an accident which necessitated
+the removal of the reservoir in order to make
+the proper repair.</p>
+
+<p>"Which is the fastest machine?" asked Alfred,
+while they were waiting for the return of the reservoir.</p>
+
+<p>"The Morane, by all means," replied the lieutenant.</p>
+
+<p>"I thought the Caudrons were the best?" remarked
+Ralph.</p>
+
+<p>"It depends on what you mean by <i>best</i>," answered
+the lieutenant. "The different machines
+are used for various purposes, and while speed is
+important, there are other things just as necessary."</p>
+
+<p>"What other things?" asked Alfred.</p>
+
+<p>"Well, bomb-dropping for one thing; then,
+some machines are better adapted than others for
+directing artillery fire, or for using machine
+guns," said the lieutenant.</p>
+
+<p>"The captain has a Caudron," said Alfred,
+"and he doesn't use a gun on it either."</p>
+
+<p>"No; the Caudron is admirably adapted for observations,
+and is used almost wholly in France
+for directing artillery fire," answered the lieutenant.</p>
+
+<p>"It seems to me that this machine is good for
+observing," said Ralph.</p>
+
+<p>"Yes; and it is used for that purpose, but it is<span class="pagenum"><a name="Page_97" id="Page_97">[Pg 97]</a></span>
+now being put to use for photographing purposes,&mdash;that
+is, most of the Maurice Farman types are
+so used," answered the lieutenant.</p>
+
+<p>"Why is that?" asked Alfred.</p>
+
+<p>"For two reasons; first, because you will see
+we can get a good view downward; and, second, because
+it is the most stable machine in flight, the
+latter making it especially well adapted to take
+good views," replied the lieutenant.</p>
+
+<p>"Which are the largest ships?" asked Ralph.</p>
+
+<p>"The Voisin and the Breguet, by all means.
+They are able to carry heavy loads, and are used
+as bomb-dropping machines, as their fuselages are
+especially well adapted to carry and release the
+missiles," said the lieutenant.</p>
+
+<p>"But I saw a Voisin at one of the hangars
+which had a big gun on it," said Ralph.</p>
+
+<p>"Ah, that was the Voisin Cannon, which carries
+a 37-millimetre gun," said the lieutenant. "That
+is used for bombarding captive balloons and Zeppelins,
+if the latter should ever make their appearance."</p>
+
+<p>"A 37-millimetre gun?" repeated Alfred.</p>
+
+<p>"Yes; that's about one and a half inch in your
+measure," answered the lieutenant.</p>
+
+<p>Within an hour the reservoir was again in position,
+and there was no delay in again mounting
+into the air. "We might take a little trip due
+east, as far as Toul, and north of that point we
+may have the privilege of seeing some of the enemy,"
+remarked the lieutenant, as they mounted
+the machine.<span class="pagenum"><a name="Page_98" id="Page_98">[Pg 98]</a></span></p>
+
+<p>A beautiful silver thread now appeared on the
+landscape to the east, as they reached their greatest
+altitude. Looking back there was a smaller
+thread to the west, and, apparently, the same distance
+from their viewpoint. They thus had the
+opportunity of seeing, at one glance, two of the
+most noted rivers which figure in the great war,&mdash;the
+Meuse to the east, and the Marne in the west,
+these streams at this point being within thirty
+miles of each other.</p>
+
+<p>It was, probably, imprudent for them to take an
+out-of-the-way course to reach their destination,
+but the temptation was very great. The sun was
+still shining brightly when they started from Ligny-en-Barrois,
+but it was now growing dark from
+the overspreading clouds, and as soon as Toul was
+sighted the lieutenant turned the machine northward.</p>
+
+<p>To the west it could now be seen that the threatening
+clouds were coming up, and they appeared
+to be sweeping toward the east with great speed,
+at right angles to the aviators' course.</p>
+
+<p>"I wonder what the lieutenant will do?" queried
+Ralph half to himself, as he looked at the clouds,
+and then glanced back to the officer.</p>
+
+<p>The lieutenant shook his head, and pointed the
+machine further to the left.</p>
+
+<p>"Why, I believe he is going right into it!" remarked
+Alfred in amazement to Ralph.</p>
+
+<p>But the officer now made a wide swinging turn.
+A view of the heavens indicated that the storm was
+an extensive one, and that the speed of the wind<span class="pagenum"><a name="Page_99" id="Page_99">[Pg 99]</a></span>
+had increased most alarmingly, for, in looking
+down they seemed to stand still over the little hamlet
+beneath them. The wind, into which they were
+flying, was traveling at the same speed as the machine.</p>
+
+<p>There was but one course to follow. They must
+return to the earth, otherwise they would be
+driven far over into the German lines. By setting
+the control lever so as to depress the nose of the
+machine they rapidly descended, the lever being
+intermittently drawn back to a normal position,
+so as to keep the ship on an even keel and prevent
+it from performing a loop in the air.</p>
+
+<p>The landing was easily made, notwithstanding
+the wind, and they found they were near Commercy,
+west of the Meuse, about thirty-five miles
+south of Verdun. A terrific rainstorm then followed,
+which lasted more than an hour.</p>
+
+<p>"Were you ever in a rainstorm while flying?"</p>
+
+<p>"Never but once," replied the lieutenant, "and
+that was in thunder and lightning, too, which was
+the most terrific thing I ever went through."</p>
+
+<p>"Tell us about it!" said Alfred.</p>
+
+<p>"I almost shudder at it when I stop to think of
+the hour when I faced the lightning right where it
+is made," said the lieutenant. "It was in the second
+week of the war, just east of Rheims, when
+the Germans were sweeping across the frontier
+and had passed Charleville. I had a double-seated
+Nieuporte, with an assistant handling the machine,
+while I was making observations.</p>
+
+<p>"Shortly after getting the first glimpse of the<span class="pagenum"><a name="Page_100" id="Page_100">[Pg 100]</a></span>
+moving German columns I noticed that it was
+growing dark, but when you are aloft that is not
+noticed as quickly as when on terra firma. The
+great hosts of Germans interested me intensely,
+and we kept on until I estimated that we were
+fully ten miles behind the advance columns, when
+my assistant shouted through the tube: 'Look
+back; what are your orders?'</p>
+
+<p>"I saw that to continue would be disastrous, so
+I gave the order to turn. This gave us the first
+opportunity to determine our speed, or, to state
+it more accurately, the speed of the wind, for you
+will recall that when we turned this afternoon,
+we seemed to stand still above the town.</p>
+
+<p>"Within ten minutes of the time I turned the
+machine to the west the first heavy rolling clouds
+seemed to meet us. The earth was quickly blotted
+from sight, and heavy rumblings were heard, but
+no indications of lightning. I knew that heavy
+black clouds were dangerous, and they were so
+black that it was impossible to see my assistant,
+three feet distant.</p>
+
+<p>"I could not decide what to do, so I finally
+shouted through the tube: 'keep on a straight
+course to the west,' for I knew that to land at
+that point would bring us right into the great
+German column. There was no rain falling at the
+time, but the cloud was like the densest mist. The
+machine was still moving,&mdash;that is, the engine was
+merrily humming, and my assistant's voice
+startled me as he shouted: 'There is something
+wrong; compass out of order.'<span class="pagenum"><a name="Page_101" id="Page_101">[Pg 101]</a></span></p>
+
+<p>"During the flashes I could see him pointing
+to the compass, and I leaned over, and caught a
+glimpse of the dial. The pointer was swinging
+around violently. The lightning now seemed to
+be incessant, and the rumbling of the thunders
+was weird beyond description. Sometimes, immediately
+after a vivid flash, a thick spray would
+deluge our faces."</p>
+
+<p>"What were you thinking about while all this
+was happening?" asked Alfred.</p>
+
+<p>"What impressed me most was the wonderful
+difference between the appearance of those electrical
+discharges when viewed in the usual way
+from the surface of the earth. I did not notice any
+forked lightning, nor did it show itself in streaks,
+darting hither and thither. It seemed to be more
+like balls of fire, suddenly appearing here and
+there, and when each ball burst into flame, there
+would be a crackling sound, at any rate, so it
+seemed, for I dared not stop the engine.</p>
+
+<p>"But the most remarkable thing was the odor
+which was present. It had a pungent smell, not at
+all unpleasant, but decidedly exhilarating in its
+effects. I suppose we were taking in ample doses
+of laughing gas, for I assure you that after the
+first experience, we had no particular sense of
+danger. It was most fascinating, and I felt as
+though I was being raised up on my seat. Occasionally
+I would try to figure out how this would
+end, but on the whole it was devoid of terror."</p>
+
+<p>"How long were you in the storm?" asked
+Ralph.<span class="pagenum"><a name="Page_102" id="Page_102">[Pg 102]</a></span></p>
+
+<p>"Well, I was so fascinated that I had forgotten
+to look at the watch. I held it before me, and soon
+noticed that it was nearly five o'clock, so that we
+were over an hour and a half in the thick of it.
+During this experience what gave me the queerest
+feeling was the compass, the needle of which could
+not be seen, it swung around with such velocity.
+Were we going with the storm, or not? That was
+the thing uppermost in my mind. If we were being
+carried along we might be even in Belgium by
+the time I noted the watch.</p>
+
+<p>"Then I tried an experiment. I ordered my assistant
+to make a turning movement. This convinced
+me that we were really going with the
+storm, and were now far over into German territory.
+Strange as it may seem, we were not thrown
+hither and thither; the ship sailed along smoothly.
+I feared to make the next experiment,&mdash;that is, to
+direct the machine toward the earth, for, while
+everything worked perfectly, I had a feeling that
+it would be safer to reach the earth with an engine
+running than with a dead one. Slowly the
+machine went down; it seemed to get lighter, but
+now the thunder came in sharp claps, and the form
+of the lightning changed. I could distinctly see
+what the observer sees when on the earth, long,
+zig-zag streaks multiplied a hundred times more
+than anything I ever witnessed while on earth."</p>
+
+<p>"How high were you up when you got out of the
+clouds?" asked Ralph.</p>
+
+<p>"Seven hundred and seventy meters (about
+2,900 feet), as indicated on the barometer."<span class="pagenum"><a name="Page_103" id="Page_103">[Pg 103]</a></span></p>
+
+<p>"Could you see the earth?" asked Alfred.</p>
+
+<p>"No, indeed; the rain was pouring down; it
+was splashing over us and all about us, and I signalled
+to go up again, and we soon entered the
+clouds; but during all this time the needle of the
+compass kept spinning, so that we knew nothing of
+the direction we were traveling."</p>
+
+<p>"But couldn't you tell which way the wind was
+blowing?" asked Ralph.</p>
+
+<p>"No; we were moving with the great air current,
+sometimes sailing with it, and at other times
+against it, but with nothing below to indicate the
+direction. We could not possibly say whether we
+were going north or south."</p>
+
+<p>"I think if I should be in the air and couldn't
+see the earth I would know a way to tell which
+way the storm was moving," said Ralph.</p>
+
+<p>"How?" asked the lieutenant, as he leaned forward.</p>
+
+<p>"Why, the rain would come down at an angle, if
+the wind should be blowing, wouldn't it?" replied
+Alfred.</p>
+
+<p>"Quite true, that would be the case on the earth;
+but it would not be so up where the raindrops are
+being formed; there the little particles of water
+move along with the wind stream; but that is not
+all; when you are in a machine in a great wind
+movement, the ship must move through the wind
+in one direction or the other at all times so as to
+keep aloft, hence, whether you are going with or
+against the wind, the rain drops appear to be
+coming down at an angle, and this, in itself would<span class="pagenum"><a name="Page_104" id="Page_104">[Pg 104]</a></span>
+be sufficient to deceive you, or, at any rate prevent
+you from determining the direction in which
+you happened to be sailing."</p>
+
+<p>"How did you get down?" asked Alfred.</p>
+
+<p>"That was the interesting part of it. After
+a half hour more of flying I again ordered the
+assistant to go down two hundred meters. It was
+now evident that the storm was abating. Soon we
+again passed out of the rain clouds, and the assistant
+shouted that he had reached the level indicated.
+'Go lower,' I shouted. As we did so it
+grew lighter, and we began to feel a relief.
+'Lower yet,' I ordered. At 600 meters the rain
+poured steadily, but still nothing was visible."</p>
+
+<p>"You were up then about a half a mile," said
+Ralph.</p>
+
+<p>"Just about that," was the reply. "Soon we
+noticed a peculiar white patch, and then another.
+This was puzzle to me. 'Go still lower,' I
+shouted, and down went the machine. Then we
+saw some white houses, and I almost shouted for
+joy. But where could we be? We were passing
+over a city, a city located within the bend of a
+large river. I racked my brain to find out where
+and what it could be. If it was the river Meuse
+it might be Verdun, or Sedan, or Charleville. We
+were forced to go down still lower, and then I
+could see forts, and I felt sure we were over Sedan.</p>
+
+<p>"We were even then going east. I was so agitated
+that I could hardly speak, and motioned to
+my assistant to turn around. He understood, and<span class="pagenum"><a name="Page_105" id="Page_105">[Pg 105]</a></span>
+the ship was swung around; we were now going
+right into the blinding rain, but we were fifty
+miles behind the German advance columns, and in
+order to enable us to make more rapid progress I
+told the assistant to change the course nearly due
+south. We were flying very low, certainly not
+over a thousand feet.</p>
+
+<p>"Thus far we had not seen a soldier, or any
+evidences of warfare. In a half hour we sighted
+another stream. My heart leaped with joy, for I
+was sure it must be the Aisne. To assure myself
+of this we followed the stream for twenty kilometers,
+and then the forests of Argonne came into
+sight, thus assuring me of the position. I knew
+that the army of the Crown Prince was in that region,
+and it would not be safe to descend; I, therefore,
+directed the machine to the west, crossed the
+river, and was about to go still lower, when I heard
+a boom,&mdash;several of them.</p>
+
+<p>"This startled me, you may be sure. 'Up, up!'
+I shouted. The machine obeyed. We rose to an
+altitude of eight hundred meters, then suddenly
+the engine stopped. My assistant turned and
+shouted: 'We have no petrol.' I crawled back and
+tested the tank. It was empty. 'Volplane to the
+south,' I said. It was the only thing I could do.
+Now that the engine was silent the sounds from
+the earth were startling. There was terrific firing
+to the right and left, and all about us; but we
+must go down; there was no help for that.</p>
+
+<p>"Soon the earth again came in sight, and then
+the location of the batteries was made out by the<span class="pagenum"><a name="Page_106" id="Page_106">[Pg 106]</a></span>
+volumes of smoke, which could be seen at each
+volley. My assistant tried to hold up the machine
+as long as possible, but we were now down to 300
+meters, then the barometer registered 250. We
+both noticed a large, apparently smooth field, and
+the final volplane began. We landed a hundred
+feet from a first-line trench, and although the Germans
+made it hot for us for about fifteen minutes
+we were soon able to reach the laterals and thus
+escape their fire. But the machine was in a bad
+condition when we rescued it that night. It was
+literally shot full of holes. What is left of it is
+now in the end warehouse where the scraps are
+kept."</p>

+<h2><br />CHAPTER IX</h2>
+
+<h2>A CHAPTER OF LESSONS ABOUT THE AEROPLANE</h2>
+
+<p><br />Early the following morning there was intense
+activity in the camp, and Ralph was among the
+first to learn the cause of the excitement. Several
+army divisions had come up in the night, and were
+bound for the Verdun sector, and from the information
+obtained it was the intention of the commander
+to make a terrific assault in order to break
+the German lines north of the city.</p>
+
+<p>The lieutenant, when approached, admitted that
+they were now in for double duty. "Every man
+in the corps must report and be ready in the morning.
+There will be two days of observation, and
+then look out for some business."</p>
+
+<p>"When will we go to Verdun?" asked Ralph.</p>
+
+<p>"We are expecting orders at any moment," was
+the reply.</p>
+
+<p>During the previous afternoon more than fifty
+machines had assembled, and some of those were
+now leaving, a few going directly east, on observation
+tours, while others were circling about and
+testing the engines.</p>
+
+<p>"I am expecting a big Farman machine," said<span class="pagenum"><a name="Page_108" id="Page_108">[Pg 108]</a></span>
+Lieutenant Guyon, as he returned from headquarters
+an hour afterwards, "that is equipped
+for carrying bombs, but I am told it is one of the
+speediest machines in the service. It will easily
+carry six hundred kilos in bombs (1,200 pounds),
+and we are ordered to wait here until it arrives."</p>
+
+<p>When the boys were alone, Alfred, with a glint
+of joy in his eyes, remarked: "I think that will
+give us an opportunity to do some flying with the
+lieutenant."</p>
+
+<p>"Do you think so?" replied Ralph, elated at the
+thought.</p>
+
+<p>"I am sure of that," said a voice behind them.</p>
+
+<p>They quickly turned and saw the lieutenant, who
+had entered unobserved. They saw by the smile
+on his face that the remark was an agreeable one,
+for he continued:</p>
+
+<p>"Yes, and the machine is now here; the men are
+at work setting it up; so we might as well go over
+and help out."</p>
+
+<p>A second invitation was not necessary. Ralph,
+who was outside in one bound, rushed across the
+field, but Alfred accompanied the lieutenant to
+the commandant's office, where they were provided
+with the receipt for the machine. The lieutenant
+remained here while Alfred carried the document
+to the warehouse. Within two hours the machine
+was in condition to receive the fuel and the supplies
+usually carried in the machines for emergencies.</p>
+
+<p>When the lieutenant returned he made a careful
+inspection, and on this occasion the boys followed<span class="pagenum"><a name="Page_109" id="Page_109">[Pg 109]</a></span>
+every movement of his to learn what were
+the essential requirements in inspecting. Naturally,
+the most important thing was to know that
+every part of the frame is not only properly set
+up and the wires made taut, but that the fastenings,
+the turnbuckles, are in good condition. That
+necessitated a minute examination of every one
+of them.</p>
+
+<p>Then the planes were sighted to ascertain
+whether they were properly aligned. Sometimes
+when the planes are not exactly parallel with each
+other, the end of one, for instance, being set a little
+higher or lower than the other, it is usually corrected
+by letting out one or more sets of brace
+wires and taking up on others. This observation
+was followed by a careful look at the control
+planes. These are the sensitive parts of the
+plane, and may be likened to feelers, for the slightest
+warping of the horizontal tail planes will frequently
+cause the machine to fly with a skidding
+motion, not dangerous, but exceedingly uncomfortable
+when flying at a high rate of speed.</p>
+
+<p>"The wires leading to the control levers are always
+a source of worry to me," remarked the lieutenant,
+and he drew himself up into the rear part
+of the chassis. "You will notice that this one rubs
+along the side of that brace. I could not permit
+that," he said, as he glanced toward one of the
+workers.</p>
+
+<p>"Do you think it would weaken the brace?"
+asked Ralph.</p>
+
+<p>"No, it's not that," replied the lieutenant.<span class="pagenum"><a name="Page_110" id="Page_110">[Pg 110]</a></span>
+"The difficulty is that all these wires are stranded,
+and as soon as one of the wires wears out by the
+frictional contact, another will give way, and the
+control wire is liable to part at the most critical
+time."</p>
+
+<p>The boys had occasion to remember the lieutenant's
+warning shortly thereafter. After an examination
+of the airplane structure an investigation
+was made of the engine. The mechanic turned
+it over to be sure that the compression was all
+right. Self-starters are provided on all these machines,
+as the French learned at an early day that
+it would be unwise to depend on cranking.</p>
+
+<p>Then a thorough inspection of the pipes and
+tubing for the fuel and lubrication was made.
+The dashboard of an aeroplane is a much more
+wonderful contrivance than the dashboard of an
+automobile. The aviator must look out for several
+things not necessary when traveling on land.</p>
+
+<p>The machine which they were examining had on
+it the most improved contrivances, which had been
+found desirable, some of which were entirely new
+to the boys, one of them being the inclinometer.</p>
+
+<p>"That must be a dandy thing," said Alfred,
+pointing to it.</p>
+
+<p>"I think there are only a few of the military
+machines which are supplied with them, but the
+order has been given to put them on all the new
+machines," said the lieutenant.</p>
+
+<p>"What are the two rods for?" asked Ralph, as
+he looked at the inclinometer.</p>

+bar, on which you see the numbers, indicate the
+angle at which the machine is going. All that is
+necessary is to observe the crossing point of the
+rod over the marked bar, and it will instantly tell
+what the angle of ascent or descent is. You see an
+aviator now has so many things to think of that
+he must have devices of various kinds which will
+constantly tell him anything or any condition without
+asking for it."</p>
+
+<p>"Why, this also tells how fast the engine
+turns," remarked Alfred.</p>
+
+<p>"Of what use is that?" asked Ralph.</p>
+
+<p>"Well; if you knew that the engine was capable,
+under full throttle, to make eighteen hundred
+revolutions a minute, and the dial showed
+that the shaft was turning only one thousand, you
+would quickly get the idea that something was
+wrong," answered the lieutenant.</p>
+
+<p>"Oh, yes; and then you would start to make an
+investigation at once without waiting for the engine
+to stop," said Alfred.</p>
+
+<p>"Exactly; it is there as a warning, just as a
+headache is a warning that something is wrong, or
+a pain, which is nature's way to indicate that an
+investigation should be made without delay," answered
+the lieutenant with a nod.</p>
+
+<p>Besides the foregoing, the dash had on it a
+watch. Now, a watch may be a convenient thing
+to have on an automobile, but it is not a necessity.
+On a scouting and observation plane it is
+one of the necessary implements. Alfred laughed,
+as he looked at the neat little clock face.<span class="pagenum"><a name="Page_113" id="Page_113">[Pg 113]</a></span></p>
+
+<p>"I suppose," he said, "we could get along without
+that."</p>
+
+<p>"Of course we could," answered the lieutenant.
+"But why get along without it when we now find
+it such a necessary element?"</p>
+
+<p>"Necessary how?" asked Ralph, in surprise.</p>
+
+<p>"In determining distances, for one thing," answered
+the lieutenant.</p>
+
+<p>"A watch to tell the distance?" asked Alfred
+incredulously.</p>
+
+<p>"Yes, indeed," responded the lieutenant. "If
+you saw a puff of smoke in the distance, and
+shortly thereafter heard a boom, the distance
+could be determined almost instantaneously by
+roughly calculating 1,200 feet for every second.
+You see, the clock there has a second hand, which
+is very plain, for that very purpose."</p>
+
+<p>"But suppose there is a regular battle on, it
+would be hard to tell about the boom from any
+particular gun, wouldn't it?" asked Ralph.</p>
+
+<p>"Quite true; in such a case it would be useless
+for that purpose. Another use is in signaling,"
+continued the lieutenant. "For instance, in sending
+information to a battery, arrangement is sometimes
+made to flash the distance by means of second
+intervals."</p>
+
+<p>"How is that done?" asked Alfred, now growing
+intensely interested in the details of the dashboard
+mechanism.</p>
+
+<p>"It is an easy matter to signal numbers," answered
+the lieutenant and a favorite plan is to fly
+over the area where the enemy's battery is located,<span class="pagenum"><a name="Page_114" id="Page_114">[Pg 114]</a></span>
+then flash at that altitude. The gunner will take
+the angle, set his piece and fire, the aviator, meanwhile,
+noting the course and effect of the shot.
+By means of the watch he can determine the distance,
+counting either by the time of flight of the
+missile, or by the elapsed time between the flash
+of the gun and the landing of the shot.</p>
+
+<p>The altimeter is another very important part
+of the equipment. It is a device which tells at
+a glance how high the machine is flying, and Ralph
+looked at it with a somewhat doubtful expression.
+The lieutenant saw the questioning lines on his
+face, and instantly divined the reason.</p>
+
+<p>"You are in doubt whether the altimeter can
+be relied on? Am I correct?" he asked.</p>
+
+<p>"Well, I suppose it is all right, but almost every
+time we have been up and took the readings, we
+found we were actually hundreds of feet less than
+the altimeter actually showed, so I am wondering
+if it is possible really to tell the exact height by
+that apparatus," remarked Alfred.</p>
+
+<p>"Yes, I understand what you mean," replied
+the lieutenant. "The other day, when we made the
+long flight from Bar-le-Duc, the device we had
+showed 900 meters, for it was an automatically
+registering barometer, as all of them practically
+are. When we returned I noted on the report book
+872 meters. Did you notice that?"</p>
+
+<p>"Yes, and I wondered at it at the time," said
+Alfred.</p>
+
+<p>"I knew that the general altitude of the country
+at that place, as indicated by the topographical<span class="pagenum"><a name="Page_115" id="Page_115">[Pg 115]</a></span>
+charts, was 28 meters above sea level so I merely
+subtracted 28 from 900, and that showed how far
+up above the land we really were," said the lieutenant.</p>
+
+<p>"Of course, it's a satisfaction to know how high
+one is flying," said Ralph.</p>
+
+<p>"It is not only a satisfaction, but it is an absolute
+necessity for an aviator to know how high
+he is flying, if his mission is to convey any information
+to the batteries in the rear," said the lieutenant.</p>
+
+<p>"And how is that done?" asked Alfred.</p>
+
+<p>"By a system of triangulation," he replied.
+"In a few days we may have an opportunity to
+use the system, and I will explain it then so you
+can quickly grasp the subject."</p>
+
+<p>The air speed indicator was another interesting
+device, but at that the lieutenant shook his
+head as though doubting its general value.</p>
+
+<p>"Don't you think it's accurate?" inquired Alfred
+of the officer.</p>
+
+<p>"Oh, yes; it is as accurate as it can be made.
+In fact all devices, which are used to indicate the
+speed of the wind, are nearly perfect. That is not
+the difficulty. When it is used on a flying machine
+several new things enter into the problem, which
+makes it difficult for the instrument to be truthful."</p>
+
+<p>"What is the main trouble?" asked Alfred.</p>
+
+<p>"Well, suppose we are starting a flight against
+a wind, which is moving at the rate of, say, ten
+miles an hour," answered the lieutenant. "While<span class="pagenum"><a name="Page_116" id="Page_116">[Pg 116]</a></span>
+in flight we note that, going against the wind, the
+air speed is sixty miles. Now, if we happened to
+stop suddenly so we were poised in the air, the
+indicator would show the air speed to be ten miles,
+so that we were really going only fifty miles. If,
+now, the machine is turned so that we are going
+at right angles to the movement of the wind, although
+we may be going actually through the air
+at a speed of seventy miles an hour, the indicator
+does not register the air speed at all, because it is
+in such a position that the air does not affect it
+and the only indication we have is the speed of
+the air relative to the movement of the machine,&mdash;or,
+to put it in a better way, I might say that the
+instrument only registers, in reality, the speed at
+which the aeroplane goes through the air, and no
+more."</p>
+
+<p>"But is that the only way to tell how fast we are
+going?" asked Ralph.</p>
+
+<p>"The best test is to take the engine revolutions.
+A certain machine after it has been properly
+tested in a calm, and also in wind currents of different
+velocities, will show a record of speed with
+the engine running at certain revolutions. An experienced
+aviator can judge pretty well, by experience,
+what the speed of the wind is, and, knowing
+the propeller speed, and the direction he is
+going relative to the wind, he can make a fair estimate
+of the speed of the machine."</p>

+
+<h2><br />CHAPTER X</h2>
+
+<h2>A THRILLING EXPERIENCE IN THE AIR</h2>
+
+<p><br />It was with feelings of joy that the boys stepped
+out of their tent the following morning to learn
+that the lieutenant had decided on a trial spin in
+the forenoon, preparatory to the real start, which
+was to take place at two in the afternoon. The
+engine was turned over, and the machine held
+down while the usual hour's running test was going
+on. Everything seemed to be in order, the engine
+was stopped and another inspection made
+when the lieutenant gave the order to mount the
+machine.</p>
+
+<p>In this type of military machine the swivel gun
+is at the extreme forward end, and the pilot directly
+behind the gunner, and at a slight elevation
+above the gun. Both gunner and pilot are housed
+in, and in most cases strapped to the body of the
+machine to prevent any accidental falling out, as
+there have been numerous accidents due to men
+being thrown from their perches.</p>
+
+<p>The boys found ample room in the forward pit,
+and at a word the machine was released and glided
+forward. The new machine gave them a sensation<span class="pagenum"><a name="Page_118" id="Page_118">[Pg 118]</a></span>
+different from the former one, as it appeared
+to ride more easily and steadily. In fact,
+there is just the same difference in the motion of
+flying machines as there is in autos, some, the
+small machines, seeming to glide over the ground
+and impart every bump to the occupants, as might
+be expected of a light machine.</p>
+
+<p>A heavy flying machine, however, seems to
+move along with the utmost ease, and does not
+sway from side to side when sailing through cross
+currents. Naturally, such a machine is a more
+stable base for machine guns as well as for observation.</p>
+
+<p>Alfred's particular hobby was kodaking. On
+this occasion, the first time he had an opportunity,
+he prepared himself with a camera. The lieutenant,
+learning of Alfred's penchant in this direction,
+had a regulation government instrument sent
+over, and attached to the machine, to Alfred's surprise.</p>
+
+<p>Before starting out, the lieutenant said: "I
+want to give you some points now, in using the
+camera. Photographs, in order to have any military
+value, must be identified,&mdash;that is, they must
+be made at such altitudes, and with reference to
+certain marked characteristics on the earth, that
+we may be able to place them on the topographical
+maps of the particular section, and thus verify
+them day after day."</p>
+
+<p>"What do you mean by verifying them day after
+day?" asked Alfred.</p>
+
+<p>"I mean by that to see what changes have taken<span class="pagenum"><a name="Page_119" id="Page_119">[Pg 119]</a></span>
+place in the same view between the taking of the
+two pictures," replied the officer.</p>
+
+<p>"Well, what possible changes could take place
+in a day or two?" asked Ralph in astonishment.</p>
+
+<p>"A great many, and very important ones, too,"
+answered the lieutenant. "The camera sees what
+the eye does not notice. If a picture is taken of
+a certain section today, and the following day another
+picture is snapped, a comparison of the two
+will show whether or not there has been a movement
+of troops, or, whether or not a certain undistinguishable
+object was something movable, or
+not."</p>
+
+<p>"Is that the way the map of the enemy's country
+is made up?" asked Alfred.</p>
+
+<p>"Yes, and every detail is noted, so that when
+you commence the work be careful to notice something
+which will distinguish the exact place where
+you are located; also put down the direction of
+the flight over that same area, and the altitude at
+which we are flying."</p>
+
+<p>As the machine glided over the treetops and the
+village on the northern border of the Meuse, the
+sun shone out with intense brilliancy. They were
+going directly east, and both boys turned toward
+the lieutenant, their eyes seeming to say: "So
+you are going to take a peep at the front, by way
+of experiment?" which was exactly what the lieutenant
+purposed doing.</p>
+
+<p>The altimeter now registered 1800 meters, considerably
+over a mile high. From that point they
+could see to Verdun, and thirty miles east of Verdun,<span class="pagenum"><a name="Page_120" id="Page_120">[Pg 120]</a></span>
+could be noted the blurred outlines and surroundings
+of Metz, that greatest of all fortified
+German defences. On they went for nearly three-quarters
+of an hour until a stream of some magnitude
+appeared to the east, which they soon crossed.</p>
+
+<p>They afterwards learned that this was the
+Mosel, which flows through Metz. The latter city
+now loomed up so it could be plainly seen, and to
+their right was another town, Nancy, a fortified
+French place. They were about midway between
+the two places.</p>
+
+<p>Suddenly an aeroplane appeared to the right,
+and the lieutenant turned the machine in that direction.
+The boys were relieved to see the great
+circle on the control planes of the machine in the
+distance, which showed them it was a French
+reconnoitering airplane. In the east several other
+machines were noticed hovering about, and the
+lieutenant at first headed directly for them, but
+he soon turned to the north.</p>
+
+<p>Below were seen numerous flashes of guns, and
+they knew from this that the fighting lines must
+be along the river. The most startling thing which
+occurred was a tremendous explosion that seemed
+to be right in the machine itself, and they looked
+around startled at the suddenness of it, for everything
+seemed peaceful enough to them at that altitude.</p>
+
+<p>The lieutenant turned the machine, however, as
+he apprehended more trouble, now that the gunners
+below had so luckily secured a fair range.
+The first shot was followed in another moment by<span class="pagenum"><a name="Page_121" id="Page_121">[Pg 121]</a></span>
+another, and the lieutenant now began to dart the
+machine back and forth, and turn it in short, sharp
+circles.</p>
+
+<p>Another explosion took place, this time remarkably
+close, and pieces of the flying machine came
+down, and brushed past the boys. The lieutenant
+shook his head, as the boys glanced back. The
+machine was now circling around, a peculiar
+manoeuver, the boys thought, as they looked at
+each other for a possible explanation.</p>
+
+<p>Ralph looked back, and noticed that the lieutenant,
+with an alarmed look on his face, was constantly
+glancing back to the tail planes. The steering
+lever seemed to be jammed. Ralph had an
+idea that something was wrong, and crawled over
+the body until he was alongside of the lieutenant.
+The latter pointed to the control lever, and Ralph
+understood.</p>
+
+<p>Without waiting for instructions from the lieutenant,
+he cautiously made his way along the chassis,
+following up the wires which were indicated by
+the lieutenant. Within four feet of the tail plane
+Ralph halted. Then, reaching down, he succeeded
+in grasping a dangling wire, and held up the end
+for the lieutenant's inspection. After several attempts
+he found the other end of the wire, which
+had been severed by a shot from a shrapnel shell.</p>
+
+<p>The ship was still circling around, so without
+waiting to repair the break Ralph turned the rudder,
+and, glancing at the lieutenant, saw the latter
+smile, and then by motions direct him to give the
+control plane a still further push in the right direction.<span class="pagenum"><a name="Page_122" id="Page_122">[Pg 122]</a></span>
+It was impossible for Ralph to hear anything
+the lieutenant said, but as soon as the airplane
+was fairly headed for the west, the power
+was shut off, and the machine began to descend.</p>
+
+<p>"Good boy!" shouted the lieutenant. "Can
+you fasten them together?" he asked.</p>
+
+<p>"I am afraid not," replied Ralph. "A piece
+seems to have been shot away. But I can take
+care of it if you will only direct me to pull it to
+the right or to the left."</p>
+
+<p>"All right, then. Do you see that great patch
+of green, directly beyond the castle?" asked the
+lieutenant.</p>
+
+<p>"I can see it plainly," replied Ralph. "Shall
+I steer for it?" he asked.</p>
+
+<p>"Oh, no. We must come up from the south.
+Note the direction of the wind from the smoke.
+Make a long sweep. We are now at an altitude of
+1200 meters. We can volplane twelve kilometers
+from this height," remarked the lieutenant.</p>
+
+<p>The turn was made to the south in a long sweep,
+Ralph continually glancing forward to note the
+direction indicated by the lieutenant.</p>
+
+<p>"Now straight ahead, and hold steady."</p>
+
+<p>They were now rapidly approaching the earth;
+the machine gliding over the tops of the trees at
+the border of the forest that ran along the river
+bank. To their right, across the river, was a large
+town, Pont-a-Mousson, and the castle ahead of
+them was a large school, from which even then
+hundreds of children were emerging, and excitedly
+rushing toward the approaching machine.<span class="pagenum"><a name="Page_123" id="Page_123">[Pg 123]</a></span></p>
+
+<p>Down went the machine at a sharper angle;
+then, when close to the earth, the rear control was
+sharply turned, and the nose of the ship raised
+up, but for an instant only, when the machine settled
+down, and, after running along a hundred
+feet, stopped.</p>
+
+<p>The agitated children pressed about, and the
+lieutenant tried in vain to keep them off. Some
+more venturesome than others, after seeing Ralph
+and Alfred, began to question them. To the relief
+of the boys they learned that the French out-posts
+were less than a mile distant.</p>
+
+<p>"Let us make the repairs as rapidly as possible,"
+said the lieutenant.</p>
+
+<p>An examination showed that not only was the
+control wire cut in two places, but the vertical
+plane had its pivot shot away, thus accounting for
+the peculiar action of the lever, which seemed to
+jam whenever an attempt was made to turn it to
+the right. Ralph did not know this, while seated
+astride the body and manipulating the plane, and
+it was obvious that even though he had succeeded
+in splicing the wire, it would have been impossible,
+with the rudder in that condition, to turn by means
+of the wire controls.</p>
+
+<p>Assisted by the machinist from the garage belonging
+to the owner of the school, they completed
+the repairs in an hour, and, hungry though they
+were, they again went aloft and sailed for their
+camp, which was reached after an absence of three
+hours.</p>
+
+<p>They thus had less than a hour to get a hurried<span class="pagenum"><a name="Page_124" id="Page_124">[Pg 124]</a></span>
+meal and prepare to line up with the squadron, to
+carry out the orders for the movement to the
+north. They were now going to that section of
+the fighting line in France where the most intense
+struggles up to that time had taken place, and
+where, ever since the opening of the conflict the
+most stupendous operations were being carried
+out to gain the mastery.</p>
+
+<p>Imagine, if you can, the sight that met their
+gaze, as they took their place on the extreme right
+of the three squadrons, which were about to launch
+on this memorable occasion. They were about
+twenty miles south of the city of Verdun. The extreme
+northern aviation base was not more than
+eight miles southwest of the city, located on a level
+plain east of the forest of Argonne, and close to
+the Aire river, a tributary of the Aisne.</p>
+
+<p>The trip was a short one, as the actual flying
+distance was less than fifteen miles. Long before
+they reached the scene of the great camp, they
+could see the thousands of vehicles, and the hundreds
+of thousands of soldiers, on the highways,
+in the fields, and around the villages along the two
+main railways which threaded their way along the
+wide valleys between the Meuse and the Aire.</p>
+
+<p>During every mile of the trip they were under
+the constant vigilance of the officers, who moved
+them into echelon, formed them into squares, or
+caused them to trail in columns of two or three, the
+object being to accustom the pilots to obey and
+execute signals while in flight.</p>
+

+
+<h2><br />CHAPTER XI</h2>
+
+<h2>A FIGHT AND A LANDING IN BELGIUM</h2>
+
+<p><br />The day following their arrival at the field base,
+as it was called, they found a wonderful change in
+the order and arrangement of the place. Everything
+was done in the most systematic way. So
+many machines, from each squadron, were told off
+each morning for certain duties. Those duties
+were as follows: First, scouting. This meant ascertaining
+where the enemy was most active;
+where the batteries were located; noting the movement
+of troops, and their general character.</p>
+
+<p>Scouts generally operate in pairs, for if it is
+impossible to signal back from the ships, one continues
+the work while the other makes a signaling
+report from such point or points in the rear as will
+make the information useful.</p>
+
+<p>The next duty is to protect the scouts from interference.
+This work is carried on by the large
+ships, which are usually provided with rapid fire
+guns. They need not, necessarily, be speedy, for
+they are to keep in touch with the speedy scout
+ships, the latter of which sail around over a small
+area so the observations can be carried on as
+leisurely as possible.<span class="pagenum"><a name="Page_126" id="Page_126">[Pg 126]</a></span></p>
+
+<p>Third come the bomb-throwers, usually heavy-powered
+machines, generally not armed, as all the
+carrying power is devoted to the transportation of
+bombs. These are also guarded by the heavily
+armed machines. Sometimes, as in the case of the
+Farman machine, which the lieutenant used, they
+were used for scouting, and were also serviceable
+for fighting purposes.</p>
+
+<p>In the early period of the war there were not
+many pilots capable of doing the duty required in
+all branches of the service. It was frequently the
+case that the aviator would command a ship with
+a gun on it and do double duty, acting as scout, or
+he would chase and fight an enemy, manipulating
+the gun while manoeuvering the machine. It was
+the sort of duty in which Lieutenant Guyon was
+engaged at the time he was promoted to the command,
+and supplied with the new type of machine.</p>
+
+<p>Naturally, as commander of the squadron, he
+was at liberty to take any one he desired in his
+flights, and as he had a real affection for the boys,
+he took delight in having them accompany him on
+many of his exploits. It was the custom for the
+lieutenant to entrust the piloting of the machine
+to one of the boys, while he acted as a scout. Frequently
+Ralph would perform this duty, while Alfred,
+with his camera engaged, under the direction
+of the lieutenant, taking such photos as were
+deemed necessary to supplement the Department
+maps.</p>
+
+<p>Thus over a month was spent in scouting duty,<span class="pagenum"><a name="Page_127" id="Page_127">[Pg 127]</a></span>
+and, as the weather became somewhat chilly, especially
+in the evenings, they never went aloft without
+being well muffled up. One morning the lieutenant
+called out to the boys that they were likely
+to have a busy day before them, as the weather
+was unusually mild for the season.</p>
+
+<p>When they arrived at the hangar the machine
+was already out of the shed, and the lieutenant was
+busy with the charts in consultation with the officer
+of the day. Evidently something unusual
+was afoot, for they waited more than an hour
+before the lieutenant re-appeared.</p>
+
+<p>"You might wrap up well," he said. "I have
+ordered a good luncheon, as we shall have a good
+long scouting area to cover."</p>
+
+<p>"Which way are we going?" asked Ralph.</p>
+
+<p>"Directly across the city, and then to the east.
+There is some unusually active business going on
+between this and Metz."</p>
+
+<p>"Think I had better load up the camera pretty
+well, even though it is a little misty," said Alfred.</p>
+
+<p>"By all means," responded the lieutenant.</p>
+
+<p>It was eleven o'clock before all was ready, when
+the lieutenant, addressing Ralph, said: "After we
+pass over Verdun, going east, we cross what is
+called the La Pietrie forests. The principal towns
+we shall visit are Conflans and Briey, both within
+the German lines. Through those towns are the
+principal railway lines which supply the enemy
+forces to the west with provisions and ammunition.
+We have eight bombs aboard to be used at<span class="pagenum"><a name="Page_128" id="Page_128">[Pg 128]</a></span>
+convenient points. After lightening up the machine
+by disposing of them we may make a visit to
+Longwy, a town twenty-two miles north of Verdun.
+We ought to have good maps of the railroad
+sections over there."</p>
+
+<p>As they arose the weather was somewhat hazy,
+so it was difficult to make observations at high altitudes.
+They, therefore, ascended at available
+points, and took a number of snapshots. To the
+left the Meuse river, and the edge of the forest
+beyond were distinctly visible, although they were
+then registering an altitude of more than 5,000
+feet, and were five miles east of the river. To the
+east was an impenetrable haze, so the lieutenant
+directed the machine toward the river, and soon
+the German encampment and lines were visible
+through Barencourt.</p>
+
+<p>All were on the alert to notice signs of the enemy's
+machines, for they were now in such a position
+that the Germans would be most likely to
+observe them, but there was not an indication that
+they would be molested. They then turned the
+machine to the northeast where a bridge was visible
+in the distance, and the lieutenant shouted
+through the tube:</p>
+
+<p>"Make for the first bridge; follow the track on
+this side for a quarter of a mile, so as to give me
+a chance to aim. Then take the second bridge to
+the north further on, and in doing so pass the factory
+beyond."</p>
+
+<p>"I understand," said Ralph.</p>
+
+<p>The track was reached, and directions followed.<span class="pagenum"><a name="Page_129" id="Page_129">[Pg 129]</a></span>
+Long before they were over the bridge the lieutenant
+pushed down the lever which released a
+bomb, which could plainly be seen at first, but they
+soon lost sight of the flying missile. A moment
+later the second bomb was released. How long it
+seemed for even the first bomb to reach the earth!
+As they were directly over the bridge an explosion
+was plainly visible. The first bomb had missed the
+bridge, but before they had time to comment on it
+the second one burst at the end of the bridge, and
+one of the spans went down.</p>
+
+<div class="figcenter" style="width: 500px;">
+<img src="images/illus125.jpg" width="500" height="320" alt="A Dangerous Position" title="" />
+</div>
+
+<p>The factory was now in view. "Go down
+lower," shouted the lieutenant.</p>
+
+<p>Alfred nudged the lieutenant, and pointed to the
+north. "That looks like an airship," he said.</p>
+
+<p>"So it is," replied the lieutenant, after a hasty
+glance. "But we must attend to this little business
+first," he continued, as his foot was extended
+down to the bomb dropper.<span class="pagenum"><a name="Page_130" id="Page_130">[Pg 130]</a></span></p>
+
+<p>"You have hit it!" shouted Alfred in glee.
+"Now for the other bridge."</p>
+
+<p>They were not as successful with the last structure,
+although three bombs were expended on it.</p>
+
+<p>"Now, where is the flyer you saw?" asked the
+lieutenant.</p>
+
+<p>"It went easy just before we reached the second
+bridge," said Alfred. "I don't see it now."</p>
+
+<p>"Then I suppose we shall have to go to Longwy
+to find where it is," said the lieutenant. "Can
+you see the city beyond?" he continued, pointing
+to the north. "Go to the left of the city," he said
+through the tube.</p>
+
+<p>"Why did you tell him to go to the left?" asked
+Alfred.</p>
+
+<p>"In that way we can avoid the long range aircraft
+guns, which we know are mounted in the
+forts to the east of the town," was the reply.</p>
+
+<p>They were soon on the northern side of the
+town, and in looking south they were surprised
+to see two machines, one making for the east and
+the other seeming to fly directly toward them.</p>
+
+<p>"That fellow will be a little surprised when he
+finds what he has to deal with," said the lieutenant
+with a chuckle.</p>
+
+<p>"It's a Fokker, isn't it?" shouted Ralph
+through the tube.</p>
+
+<p>"Quite right; when I give the signal turn
+to the left, and describe a sharp circle. I'll fool
+him," said the lieutenant.</p>
+
+<p>The signal came; the machine veered around
+just as the Fokker came plainly into sight. As<span class="pagenum"><a name="Page_131" id="Page_131">[Pg 131]</a></span>
+the turn was made the lieutenant turned the machine
+gun to the other side, and when the sight
+was cleared past the wings he gave the first turn
+of the crank to the gun.</p>
+
+<p>There was a hum and a succession of cracks,
+which seemed to surprise the man in the Fokker.
+He evidently thought that the French machine was
+trying to get away, or it never would have ventured
+so close.</p>
+
+<p>"The other machine is coming!" cried Alfred.</p>
+
+<p>"Here is where we can get in the fun," said the
+lieutenant. "Make a straight line for the one
+coming up in the east. Go on until I signal."</p>
+
+<p>This was a most audacious move, and while
+Ralph was guiding the machine toward the
+stranger the lieutenant poured a constant stream
+of shot into the first comer. It must not be
+assumed, however, that the German machines
+were idle during this period. Both were firing,
+but the shots went wild, especially after the daring
+move just made.</p>
+
+<p>"Up! up! as high as you can go!" was the next
+order.</p>
+
+<p>The machine tilted, and the lieutenant looked
+back at Ralph approvingly. "She is a dandy
+climber," said the lieutenant musingly. "Now
+I'd like to see them follow a bit."</p>
+
+<p>One of the machines actually tried to imitate
+them, but the other ship was noticed wavering
+and swaying from side to side.</p>
+
+<p>"Something is the matter with that fellow,"
+said Alfred.<span class="pagenum"><a name="Page_132" id="Page_132">[Pg 132]</a></span></p>
+
+<p>"Yes; he's done for, and we can easily polish
+off the other one," remarked the lieutenant, as
+he watched the falling machine. "Now turn
+around quickly and dive for the one who is trailing
+us," said the lieutenant through the tube.</p>
+
+<p>Ralph banked the machine, and brought it
+around as quickly as possible. The machine was
+not a quick-turning one, but the oncoming machine
+was not prepared for the manoeuver, for
+it seemed to hesitate which way to go. If it went
+to the left it would be impossible to use its gun,
+and if it turned to the right it would be at the
+mercy of the Frenchman's gun. The only remedy
+was to dive; down went the machine at a sharp
+angle. The lieutenant's shots went wild, but
+they were soon rid of their troublesome companion.</p>
+
+<p>"I suppose we'll have the whole German flying
+corps after us now," said the lieutenant. "Turn
+for home."</p>
+
+<p>No sooner had they turned than another machine
+came up, this time a most determined
+fellow.</p>
+
+<p>"Up! up!" again came the command, "and keep
+pointing that way. You might also veer to the
+left."</p>
+
+<p>This time it was one of the well-known Taubes,
+with the disadvantage, however, that she was a
+tractor,&mdash;that is, had the propeller in front, like
+the Bleriot monoplane, so that it prevented the
+driver from shooting head on, whereas the Farman
+biplane was a pusher,&mdash;that is, had the gun<span class="pagenum"><a name="Page_133" id="Page_133">[Pg 133]</a></span>
+mounted in front, and the propeller behind the
+planes. During the evolution of circling, however,
+the biplane had to present a broadside, which
+gave the Taube a chance to pour in a stream of
+shot, many of which took effect.</p>
+
+<p>"That was a close shot!" shouted Ralph
+through the tube. The lieutenant looked back,
+and pointed to the tube. A shot had gone through
+it, causing Alfred and Ralph to look at each other
+in undisguised dismay.</p>
+
+<div class="figcenter" style="width: 500px;">
+<img src="images/illus129.jpg" width="500" height="336" alt="A Safety Manoeuver" title="" />
+</div>
+
+<p>At every turn the lieutenant ground out the
+shot, and soon the barometer registered a height
+of 6,400 feet. Two miles more and the Taube
+made a peculiar turn, and glided to the right.</p>
+
+<p>"You have hit him," said Alfred in excitement,
+and the lieutenant stopped churning.</p>
+
+<p>"It seems like it," was the reply. "When we
+come back on the circle, go lower," he said to
+Ralph, "and I can finish him."<span class="pagenum"><a name="Page_134" id="Page_134">[Pg 134]</a></span></p>
+
+<p>As they crept up closer and closer, the lieutenant,
+with his hand on the crank, waited for the
+final chance. Like a dying gladiator the Taube
+turned, and a most terrific storm of shot came
+from the quick firer. This was the only time that
+the boys actually heard the thuds of the striking
+missiles on the body of the machine. It proved
+to be the last effort of the Taube; it dropped away,
+but still held its upright position.</p>
+
+<p>Instantly the engine of the biplane stopped.
+The lieutenant, with his hand still on the crank,
+turned and shouted:</p>
+
+<p>"What is the matter?"</p>
+
+<p>There was dead silence, and sudden darkness,
+for they could not see in either direction. They
+had entered a dense cloud.</p>
+
+<p>"Have we started on the down glide?" continued
+the lieutenant.</p>
+
+<p>"I am trying to hold it up," said Ralph. As he
+spoke they emerged from the cloud, but the Taube
+was nowhere in sight.</p>
+
+<p>"Try the starter," said the lieutenant feverishly.</p>
+
+<p>"Can't do it," was the reply.</p>
+
+<p>"Then hold it steady while I examine the tank,"
+said the lieutenant. He leaned over, and almost
+immediately exclaimed: "The connection is shot
+away."</p>
+
+<p>"I will make a long glide if you can fix it in the
+meantime," said Ralph.</p>
+
+<p>"No; I will connect the other tank," was the
+reply.<span class="pagenum"><a name="Page_135" id="Page_135">[Pg 135]</a></span></p>
+
+<p>It required less than a minute to perform this
+operation, but despite the repair the engine would
+not turn.</p>
+
+<p>After another examination the lieutenant
+looked up from the pit, and said: "It's all up now.
+The other tank is also empty."</p>
+
+<p>The barometer now showed that they were only
+a little over three thousand feet above the earth.
+A landing must be made, that was evident; but
+where? Alfred pointed to a forest, directly east.</p>
+
+<p>"That might be a good place to come down, because
+there doesn't seem to be any houses there."</p>
+
+<p>"Just the place if we can find a spot
+big enough," said the lieutenant.</p>
+
+<p>With his field glasses he scanned the forest.</p>
+
+<p>"Do you see that strip of dark green a little
+to the left? That is a clear space, I am sure.
+Steer for that after circling around. We are still
+high enough to enable us to make a careful observation
+of the spot."</p>
+
+<p>The machine descended in its regular glide, and
+they passed over the indicated spot.</p>
+
+<p>"That is a dandy place if you can hit it right,"
+said Alfred.</p>
+
+<p>It was narrow, not more than a hundred feet
+wide, but it extended diagonally up the hill, not
+the most desirable place to land, by any means,
+but it was the only thing to be done.</p>
+
+<p>"Where shall I land?" asked Ralph.</p>
+
+<p>"Try to strike the second clump of brush; do
+you see what I mean?" asked the lieutenant, his
+words tumbling over each other in his haste.<span class="pagenum"><a name="Page_136" id="Page_136">[Pg 136]</a></span></p>
+
+<p>"I can do it," was the reply.</p>
+
+<p>"May you have good luck," said the lieutenant.</p>
+
+<p>They approached the end of the open space between
+the trees. Fortunately the wind was not
+blowing, and the fuselage struck the first clump
+of brush, but they passed over it without difficulty.
+Ralph then threw up the elevator sharply, and the
+front end tilted, while the body of the machine
+sank down gently, and the landing was made without
+a jar.</p>
+
+<p>"That was the most beautiful thing I ever saw.
+You deserve great credit for that piece of work,"
+said the lieutenant, as he leaned back and patted
+Ralph.</p>
+
+<p>They leaped from the machine, and for a moment
+stood there helpless with the reaction which
+set in, the boys, particularly, being influenced by
+the great strain. The lieutenant was the first to
+speak: "Well, here we are in a pretty fix; but it
+might be worse," he said.</p>
+
+<p>"No; we haven't a drop of petrol left," said
+Ralph ruefully. "Both tanks were perforated."</p>
+
+<p>They sat down to consider the situation. It was
+now past five o'clock, and although it was generally
+the custom to take luncheon with them on
+these trips, the extra amount which had been
+stored was barely sufficient for a half meal. The
+sun was going down, and they had no idea of their
+location except that, by calculating, the lieutenant
+judged they might be fifteen miles northeast of
+Longwy. Everything was still, except the evening
+chirrup of the birds.<span class="pagenum"><a name="Page_137" id="Page_137">[Pg 137]</a></span></p>
+
+<p>"It is too late to do any investigating tonight;
+but our first duty in the morning must be to arrange
+for food," said the lieutenant.</p>
+
+<p>Fortunately, they had taken the precaution to
+carry plenty of wraps, so they were not at all
+uncomfortable. They gathered leaves, made up
+comfortable berths, and, after a most exciting day,
+slept soundly all night.</p>
+
+<p>As soon as the first grey of the morning sun
+lightened up they arose, and began an investigation
+of the surrounding vicinity. A reconnoitering
+journey was proposed, as, during the night,
+faint whistles of locomotives could be heard coming
+from the east.</p>
+
+<p>"That is the direction we must go," said the
+lieutenant, as they prepared themselves for the
+trip.</p>
+
+<p>They entered a dense forest, setting their course
+by the compass, and marched due east for an hour
+without seeing the first sign of habitation, when
+they were suddenly startled by a locomotive whistle,
+which could not be more than a mile away.
+They drew back and listened for a time, then cautiously
+crept forward, looking for an opening.
+A quarter of a mile to the left they discovered a
+wagon trail leading to the north.</p>
+
+<p>This began to look as though some one might be
+living in the vicinity. The trail was followed, as
+cautiously and as closely as possible, and a mile
+beyond a cabin was sighted. This was the time
+for them to exercise care, but they felt sure the
+people living there would sympathize with them.<span class="pagenum"><a name="Page_138" id="Page_138">[Pg 138]</a></span></p>
+
+<p>"You see, we are in Belgium now, and they hate
+the Germans," said the lieutenant. "I suppose
+we are close to the border of Luxemburg, and the
+people there feel the same as the Belgians."</p>
+
+<p>"Do you know a place in Belgium called Bovigny?"
+asked Ralph.</p>
+
+<p>"Yes," responded the lieutenant. "That is on
+the other side of Luxemburg, close to the frontier.
+Why do you ask?"</p>
+
+<p>"That is where we entered Belgium, and near
+where we assisted in capturing the auto load of
+Germans," said Alfred.</p>
+
+<p>"Yes, Bovigny is less than forty miles from
+this place," said the lieutenant.</p>
+
+<p>"Isn't that strange," said Ralph. "Here we
+are, close to the place where we started on this
+excursion. Why, we made a regular circle to get
+here," and they laughed at the situation.</p>
+
+<p>It was now past six o'clock in the morning. No
+one was in sight, and they assumed it might be too
+early for the people, so they waited for an hour;
+still there was no sign that the cabin was occupied.</p>
+
+<p>"I suppose we might as well go closer and investigate."
+They went forward without seeing a
+sign of life, except a dozen or more chickens,
+which were scattered over the lawn to the rear of
+the cabin. "If there is any one there a whistle
+might bring them out," continued the lieutenant.</p>
+
+<p>There was no response, and after waiting a
+short time they circled about the house, and they
+saw that the front door was open, but there was<span class="pagenum"><a name="Page_139" id="Page_139">[Pg 139]</a></span>
+no furniture within. They then boldly approached,
+and began to examine the contents of
+the rooms. Not a scrap of food was found, although
+ants and other vermin were numerous,
+and there was a mouldy smell in the second room,
+there being only two compartments or rooms.
+While they were searching about, two chickens appeared
+at the door, and with a common instinct
+the boys encouraged a closer acquaintance, to the
+amusement of the lieutenant. One of the chickens
+was finally trapped, and a meal was soon prepared
+and cooked in the oven. They had barely time to
+finish the repast, when a shot was heard in the
+woods to the south, at which they hurriedly left
+the cottage, and rushed to the nearest clump of
+brush across the clearing. A second shot followed,
+evidently quite near, but apparently from
+the same direction as the first.</p>
+
+<p>"They are probably hunters," remarked the
+lieutenant.</p>
+
+<p>"Isn't our machine over in that direction?"
+asked Ralph.</p>
+
+<p>"Undoubtedly," said the lieutenant.</p>
+
+<p>"I wonder what they would do if they found
+it?" queried Alfred.</p>
+
+<p>"I think it would be perfectly safe if the hunters
+are natives. I am sure they would suspect
+the truth, for they would at once recognize it as a
+French machine," replied the lieutenant.</p>
+
+<p>"Would it be safe to go in that direction?"
+asked Alfred.</p>
+
+<p>"That was in my mind," replied the lieutenant.<span class="pagenum"><a name="Page_140" id="Page_140">[Pg 140]</a></span>
+"As we must find some one in this region, and
+they seem to me to be the most likely fellows to
+approach, come on," he added.</p>
+
+<p>They hurriedly went forward, expecting every
+minute to catch sight of the hunters. Their progress
+was slow, as the ground was full of leaves,
+and the wood thick; besides, there was considerable
+underbrush. They thus wearily tramped on
+and on for more than an hour, covering a distance
+which should have brought them close to the location
+of their machine. Despite all their efforts
+it could not be found nor the place located.</p>
+
+<p>The only remedy was to retrace their steps and
+go back to the cabin, and from that place they
+could readily follow the wagon road back to the
+place where they emerged from the woods. The
+cottage was reached shortly after noon, and an
+hour was spent in catching several of the chickens
+and roasting them, so that it was in the middle
+of the afternoon before they again retraced
+their steps back to the starting point.</p>
+
+<p>Here another difficulty presented itself. They
+could not find the place where they first reached
+the trail, so they sat down to wait for the welcome
+sound of a train to guide them. Even that aid
+was denied them, and as darkness was now coming
+on a suitable place was found to rest for the
+night at the base of an uprooted tree. There the
+night was spent in comparative comfort, as, fortunately,
+the weather still continued mild and agreeable.</p>
+
+<p>The matter of food now became a vital one, but<span class="pagenum"><a name="Page_141" id="Page_141">[Pg 141]</a></span>
+so, also, was the necessity of locating the airplane.
+The matter was debated, and the lieutenant finally
+said: "We must find our machine; from that point
+I think we should strike to the west. It would be
+unwise for us to approach the railroad to the
+east, as that is in the hands of the Germans, and
+every mile of it is patrolled."</p>
+
+<p>By means of the compass they trudged to the
+west, and soon reached familiar ground. As they
+were about to enter the open space, which was
+recognized as their landing place, voices were
+heard. The three glanced at each other in dismay,
+until Alfred's keen ears detected a French word
+or two, of which he quickly advised his companions.</p>
+
+<p>"I will call to them in French," said the lieutenant.</p>
+
+<p>He did so, and the two men, for the lieutenant
+could now distinctly see them, were startled, but
+in another moment returned an answer.</p>
+
+<p>"We are French," said the lieutenant. "That
+is our machine, and we have been reconnoitering."</p>
+
+<p>"We are friends," said one of the men.</p>
+
+<p>In another moment the lieutenant and the boys
+were at the machine, and grasped the hands of the
+hunters. "We are Belgians," continued the
+man.</p>
+
+<p>"Where are we?" asked the lieutenant.</p>
+
+<p>"In the forest, north of Messanoy," was the reply.</p>
+
+<p>"Are there any Germans near?" asked the lieutenant.<span class="pagenum"><a name="Page_142" id="Page_142">[Pg 142]</a></span></p>
+
+<p>"Yes, at St. Leger, to the north, and at the
+junction of Arlon, to the northeast. But troops
+are constantly going along both roads to Longwy
+and Metz," replied one of the spokesmen.</p>
+
+<p>"Where can we get something to eat?" was
+asked.</p>
+
+<p>"Ah, we can arrange that," said one of the men
+with a smile. "Follow us."</p>
+
+<p>On the way the lieutenant learned a great deal
+of the system in force by the Germans. They were
+conducted north, through the woods for fully a
+mile where they reached a wagon trail. Here the
+lieutenant stopped.</p>
+
+<p>"Where does this trail lead?" he asked.</p>
+
+<p>"From the railway station on the east line to
+a little village on the west side of the forest," was
+the answer.</p>
+
+<p>"Then we were on this trail yesterday," said
+Ralph.</p>
+
+<p>If they had gone a quarter of a mile farther,
+after reaching the cottage, they could have seen
+the first cottage in the village. It was also learned
+that the two men were the hunters whose shots
+were heard the previous day while at the cabin.
+The men lived a quarter of a mile from the village,
+in the elevated part, near the border of the forest,
+and like true Belgians were glad to help their
+French brothers.</p>

+
+<h2><br />CHAPTER XII</h2>
+
+<h2>EXCITING EXPLOITS ON LAND</h2>
+
+<p><br />"That is the place where I live," said the elder
+of the two men, as he pointed to a low cottage on
+the side of a hill, "and Raoul here lives below the
+turn. We must approach the house cautiously, for
+we know spies to be in this part of the country."</p>
+
+<p>"I will go ahead," said Raoul. "Follow and
+go up to your house through the orchard."</p>
+
+<p>They tarried by the roadside until the signal
+appeared. Upon reaching the house they were
+greeted by Felix's wife, for that was the name
+Raoul bestowed on his friend. A good meal was
+soon spread before them, and in the meantime the
+lieutenant was plied with questions, as the people
+in that section had no opportunities for learning
+what was really taking place in the outside world.</p>
+
+<p>Finally the lieutenant asked: "Do you know of
+any place where we could get some petrol?"</p>
+
+<p>The men mused for a while, and shook their
+heads. "You know," Felix said, "everything
+around here is controlled by the Germans, and
+petrol is one of the things that is kept strictly
+under guard."<span class="pagenum"><a name="Page_144" id="Page_144">[Pg 144]</a></span></p>
+
+<p>"Do you know the place where they store it?"
+inquired the lieutenant.</p>
+
+<p>"Yes, but it would be dangerous to attempt to
+get any of it," said Raoul.</p>
+
+<p>"I have a plan," said Felix, "but we cannot do
+anything before night. I know every step of the
+way to the station, and will take you there this
+evening."</p>
+
+<p>"Good!" said the lieutenant. "In the meantime,
+give me a diagram of the station, and the
+roads leading to it. That will help me to become
+familiar with the surroundings."</p>
+
+<p>For the next hour the lieutenant was busily
+engaged in learning all about the country, and
+where the stores and ammunition were kept.</p>
+
+<p>"I think we might as well have some of that
+petrol," said the lieutenant with a smile, as he
+looked at the boys, who nodded their approval, as
+they were keen to participate in the plans which
+the lieutenant had formed.</p>
+
+<p>That night, after ten o'clock, they appeared at
+their place of concealment, for it was thought wise
+to keep away from the house in the event any of
+the prying neighbors should happen in. Together
+they cautiously found their way to the railway
+and walked along the track until the first switch
+was reached. While waiting there so that Felix
+could point out the different objects, Ralph drew
+the lever, and set it so the first train would take
+the switch.</p>
+
+<p>The lieutenant saw it and nodded approvingly.
+Ahead a few hundred feet was a low building,<span class="pagenum"><a name="Page_145" id="Page_145">[Pg 145]</a></span>
+which was reached by the track which led from
+the switch.</p>
+
+<p>"The guards are stationed at that shed across
+the track, and sometimes they come over," said
+Felix.</p>
+
+<p>"But is the building open?" asked the lieutenant.</p>
+
+<p>"There are no doors; only open arches. The
+tanks can be loaded and unloaded from the
+tracks," was the answer.</p>
+
+<p>They were carrying three vessels, such as are
+usually employed for transporting petrol in small
+quantities, and nearing the shed the lieutenant
+said: "Remain here and await my orders. I will
+go ahead and investigate."</p>
+
+<p>With two of the receptacles in his hands he
+crouched as low as possible, and made his way
+along the track, but before reaching the structure
+he left the track, and approached the shed from
+the south side. He was gone for more than fifteen
+minutes, and when he returned with the receptacles
+filled he immediately seized the other,
+returning with it also filled in a few minutes.</p>
+
+<p>"Now, take these to the cross road, and out of
+sight. I will be there in fifteen minutes," and
+saying this he quietly left them.</p>
+
+<p>The boys and Felix carried the cans to the
+designated place with the greatest care, for the
+fluid was precious to them. No sooner had they
+hidden the receptacles when something like a flash
+of lightning illuminated everything about them,
+and this was followed by an explosion.<span class="pagenum"><a name="Page_146" id="Page_146">[Pg 146]</a></span></p>
+
+<p>Felix gasped as he gazed in the direction of the
+sheds, for he divined the cause. The boys, too,
+were startled.</p>
+
+<p>"I wonder if the lieutenant did that?" asked
+Ralph.</p>
+
+<p>"I have no doubt of it," replied Felix.</p>
+
+<p>"Do you really think he did it? I wonder if
+he is hurt?" said Alfred, his voice in a tremor.</p>
+
+<p>They waited for more than a half hour. What
+if the lieutenant had been caught in the catastrophe?
+They could see the soldiers at the station
+rushing hither and thither, and the people were
+going toward the station from all directions.</p>
+
+<p>"Mighty good thing we hid in this place," said
+Felix.</p>
+
+<p>Felix and the boys were now in consternation,
+and as they had about decided to go up to their
+former place of concealment, the headlight of a
+train approached from the south. It slowed down
+a little as it neared the station.</p>
+
+<p>"The switch!" was Ralph's exclamation. As
+he said that the train reached the switch, and
+turned to the track leading to the fiercely burning
+shed. Half of the train ran through a sea of fire
+before it could be checked. It was a terrifying
+sight, and Ralph shook with fear at the sight.
+Fortunately, it was a freight train, or the toll of
+death would have been awful.</p>
+
+<p>"This begins to look bad for us. I am afraid
+the lieutenant has been captured. This place is
+getting to be too dangerous, and we must leave at
+once," said Felix, as he seized one of the cans.<span class="pagenum"><a name="Page_147" id="Page_147">[Pg 147]</a></span></p>
+
+<p>"I will go down and see what the trouble is,"
+said Alfred, but Felix shook his head. Nevertheless,
+although Ralph also remonstrated, and insisted
+on accompanying him, Alfred had his way.
+One would be safer than two, he thought, and without
+further words he crawled along the fence,
+avoiding contact with those who were in the near
+vicinity.</p>
+
+<p>A few minutes after Alfred left, the lieutenant
+returned, and was shocked to learn of Alfred's
+journey.</p>
+
+<p>"Take these cans up to the house, and I will go
+back and try to find him," he told them.</p>
+
+<p>Alfred, meanwhile, had reached the track near
+the switch, and not far from the rear end of the
+burning train. As he was about to cross the track
+his foot struck an object, and he fell across the
+track. He was surprised to see several men appear
+and gaze at him, and it must be admitted that
+he was decidedly nervous over the situation.
+However, he did not venture to say anything, but
+quickly started at the fire, for he now stood with
+others, in the full glare of the flames. As no one
+paid any attention to him, it occurred to him that
+he had as much right there as the villagers.</p>
+
+<p>All about him he heard criticisms of the calamity,
+and some one suggested that the fire and explosion
+was caused by a French airship, and, in
+fact, this seemed to be the general opinion.</p>
+
+<p>Alfred wandered about listlessly, now feeling
+assured that the people knew nothing of the lieutenant,
+for he was certain that the news of the capture<span class="pagenum"><a name="Page_148" id="Page_148">[Pg 148]</a></span>
+of a Frenchman would cause great excitement.
+Waiting the first opportunity, he slipped
+over the fence, and crawled along in the shadow of
+some brush for several hundred feet, when, to his
+consternation, a tall man arose in his path.</p>
+
+<p>He turned, and was about to leap the fence,
+when he heard a familiar voice: "Alfred."</p>
+
+<p>He immediately recognized the lieutenant, and
+it is questionable which of the two felt happier
+at the meeting. They quickly ascended the hill,
+where they met a gloomy pair in Ralph and Felix,
+and the lieutenant told his story. He had allowed
+the petrol to run from one of the tanks after he
+took away the last receptacle, and when he returned
+he tapped three of the other tanks, expecting
+to wait five or ten minutes before firing it.</p>
+
+<p>While thus waiting two of the guards approached,
+and he hid behind a box car on the opposite
+siding. He feared that his plans had miscarried,
+for he felt sure the guards would discover
+the petrol. They did not, however, go into the
+sheds, but remained outside, engaged in conversation
+for more than ten minutes. When they left
+he lost no time in again crossing the track.</p>
+
+<p>He reasoned that the whole of the interior of
+the first set of sheds must have been flooded by
+that time, and the problem now was to ignite it,
+and get away safely, so he struck a match and
+lighted a small saturated cloth, which was thrown
+into the nearest opening. It caught instantly, and
+as the entire shed was now filled with the vapor,
+the explosion followed before he could get across<span class="pagenum"><a name="Page_149" id="Page_149">[Pg 149]</a></span>
+the track. It was so great in violence that he was
+hoisted from his feet, so it seemed to him, and
+completely stunned. How long he remained in
+that condition of half stupor he did not know, but
+he soon heard a babel of voices, and saw everything
+about him as bright as day. Then, to his
+surprise, a train came up the switch, and rushed
+through the fire. It was this which probably saved
+him from being detected.</p>
+
+<p>"You may be sure," he said, "that as soon as
+my senses returned I knew what had happened,
+and that train started my sluggish brain into activity.
+I ran away from the train, and so did several
+others. No one cared to follow me, thinking,
+of course, that I belonged to the crew. That explains
+my long absence."</p>
+
+<p>"Now, how are we to get the petrol over to the
+machine?" asked Ralph.</p>
+
+<p>"We must ask Felix about it," said the lieutenant.
+"Probably you can help us out in that direction?"</p>
+
+<p>"I have a light wagon," said Felix, "but we
+must not venture out with it until after midnight;
+in the meantime I will go down to the village and
+get all the news."</p>
+
+<p>He returned in an hour. "It is reported that
+an airship did the damage," said Felix.</p>
+
+<p>Shortly after two o'clock in the morning the
+light wagon was on hand, and Raoul accompanied
+them. After loading the wagon with the cans they
+started on the trip through the forest. Felix and
+Raoul both remained with the lieutenant and the<span class="pagenum"><a name="Page_150" id="Page_150">[Pg 150]</a></span>
+boys until the tanks were repaired, and the sun
+had appeared. The machine was then turned
+around, and headed for the opening in the forest
+through which they had entered. Felix and Raoul,
+in the meantime, diligently cut away the underbrush
+and bushes in the path of the machine so it
+would be able to make a fair start.</p>
+
+<p>The boys now mounted the machine after shaking
+hands with the two men, and the lieutenant,
+reaching into his pocket, drew out a hundred franc
+note, which he tendered to them. They refused
+to take it. The lieutenant then threw it on the
+ground, saying: "This belongs to Belgium, and
+you had better take it."</p>
+
+<p>"Good bye, and God bless you," shouted Felix,
+as the motor began to hum. The machine gliding
+down the incline quickly gathered speed, and it
+was soon in the air.</p>
+
+<p>After reaching an altitude of a thousand meters,
+the lieutenant said: "It would be interesting to
+pay the village a visit after our pleasant experience
+there."</p>
+
+<p>Ralph, accordingly, turned the rudder, and the
+machine swung to the right. It required only a
+few minutes to reach the scene, and there, notwithstanding
+the distance, they could see the blackened
+and still smoking ruins in the two immense
+spaces adjoining the station.</p>
+
+<p>Now, for the first time, they appreciated the fact
+that a worthy task had been accomplished, for this
+station was one of the most important oil supply
+points along that whole line.<span class="pagenum"><a name="Page_151" id="Page_151">[Pg 151]</a></span></p>
+
+<p>The soldiers were rushing wildly about the station
+grounds, and the officials there were no doubt
+now assured, after seeing the machine, that the
+depot had actually been destroyed by a bomb from
+that airplane.</p>
+
+<p>The machine was now directed toward Longwy,
+and after giving that city a wide berth, flew directly
+south, with Verdun as the objective. The
+grounds below and to the west of that city were
+reached before ten o'clock, to the astonishment of
+the men quartered there, for it had been reported
+the night before that the lieutenant and the boys
+had been captured or killed in the fight at Longwy.</p>
+
+<p>The lieutenant won the cross for the exploit, and
+the boys received honorable mention from the government.</p>

+
+<h2><br />CHAPTER XIII</h2>
+
+<h2>A DARING BOMB RAID TO THE RHINE</h2>
+
+<p><br />The exploits of the lieutenant and the boys soon
+became the talk of the camp. From enemy sources
+more was learned later about the results of the
+destruction of the oil station, which fully confirmed
+the earlier reports of the great damage
+which had been done. Although up to this time
+there had been some objection raised against the
+flights of the boys it must be said that after that
+event there was no one to criticise them.</p>
+
+<p>During the winter months not much was done
+excepting scout work, as the weather was too severe
+for the men in the trenches to attempt any
+advances, but as the spring months came on everything
+became more active, thus imposing greater
+duty on the air fleet.</p>
+
+<p>Not much of personal interest to the boys took
+place until May, when the great raid was planned
+to attack the munition factories and chemical
+works at and near Ludwigshafen, on the Rhine.</p>
+
+<p>"Ralph, did you hear that there is going to be
+a big expedition this week right into Germany?"
+said Alfred, who had been with the lieutenant at
+headquarters early one morning.<span class="pagenum"><a name="Page_153" id="Page_153">[Pg 153]</a></span></p>
+
+<p>"No, although the boys are always talking about
+something of that kind," replied Ralph.</p>
+
+<p>"But this is a sure go; the lieutenant told me
+so a few minutes ago," responded Alfred.</p>
+
+<p>"Is the lieutenant going, do you know?" asked
+Ralph.</p>
+
+<p>"Yes, I suppose that is why he told me about
+it," answered Alfred.</p>
+
+<p>"I wonder whether they will let us go with
+him?" asked Ralph.</p>
+
+<p>"Well, I didn't ask him, but I looked at him
+pretty hard, and I guess he knows how we feel
+about it," answered Alfred.</p>
+
+<p>The rumor turned out to be true, for the following
+day orders were formally received to prepare
+eighteen machines for a raid to the Rhine. The
+lieutenant announced the news to the boys, and
+added: "I suppose, of course, you wouldn't like
+to go on such a venturesome mission?"</p>
+
+<p>"Go!" exclaimed both boys in unison.</p>
+
+<p>The lieutenant laughed. "Well, if you insist on
+it I shall have to take you with me. The Seraph
+(which was the name of their airplane, although
+it was officially known as No. 47) will be fixed to
+carry a dozen bombs for the occasion."</p>
+
+<p>"But how about the quick firer?" asked Ralph.</p>
+
+<p>"We must dispense with that on this trip.
+Bombs are more valuable," answered the lieutenant.</p>
+
+<p>"Well, aren't we going to take any guard ships
+along?" inquired Alfred.</p>
+
+<p>"Oh yes; six of the machines will be armed, but<span class="pagenum"><a name="Page_154" id="Page_154">[Pg 154]</a></span>
+we must use every ounce we can carry on the
+Seraph. Before starting we must go over the
+route, as similar instructions will have to be issued
+to all of the flyers," remarked the lieutenant.</p>
+
+<p>"Do you know where we are to go?" asked
+Ralph.</p>
+
+<p>"The objective point is Mannheim on the Rhine.
+The river is eighty miles due east, and Mannheim
+is about fifty miles farther down the river. That
+city is on the eastern bank of the river, and Ludwigshafen
+is a small town, on the opposite shore
+where the great laboratory of Badische Analin
+and Soda Fabrik is located," remarked the lieutenant.</p>
+
+<p>"So we are going to destroy a soda factory?"
+said Ralph with a grin.</p>
+
+<p>"Not exactly," replied the lieutenant, amused
+at the intimation. "The principal thing turned
+out at the plant before the war was nitrate, a
+chemical most essential in the manufacture of explosives,
+and the importance of the place may be
+understood when I tell you that fully two-thirds of
+this product used by the Germans comes from that
+place."</p>
+
+<p>"When will the start be made?" asked Ralph
+excitedly.</p>
+
+<p>"Tomorrow," was the reply.</p>
+
+<p>"Then I want to see the map," said Ralph.</p>
+
+<p>"By all means," answered the lieutenant.
+"Now, you will notice that here is a canal shown
+on the map which runs due east. That is the
+Rhine-Marne, which parallels this river, the Zorn.<span class="pagenum"><a name="Page_155" id="Page_155">[Pg 155]</a></span>
+The Zorn flows into the Rhine at Strassburg. You
+know, of course, that rivers, or canals, are the
+best guides for our purposes, so we must get these
+firmly fixed in our minds."</p>
+
+<p>"Yes, that and the towns are sure to carry
+us along without mistake," remarked Alfred.
+"What is that place, Saarburg? It is on the
+river."</p>
+
+<p>"That is an ancient town, and you can hardly
+fail to recognize the place, for it is surrounded by
+a great stone wall. It also contains a strong garrison.
+Now note the next important place, twenty
+miles farther on; that is Zabern. From that place
+we can see the Rhine at various places, as we intend
+to fly at an altitude of two thousand meters,
+or, as you would say, 6500 feet."</p>
+
+<p>"Why is it necessary to go to such a high altitude?"
+asked Alfred.</p>
+
+<p>"Because at Saarburg, Zabern and Brumath
+they have long range anti-airship guns, and we
+cannot take any chances," replied the lieutenant.</p>
+
+<p>The camp was a seething place of excitement the
+following morning. Twelve of the machines carried
+bombs exclusively; some of the airplanes had
+six bombs, each weighing 180 pounds; one had
+three bombs of 300 pounds each, and the Seraph
+carried ten 120-lb. high-explosive cylinders.</p>
+
+<p>These were placed in a suitable case having
+compartments, the lower ends of the compartments
+being provided with outwardly opening
+doors, capable of being released by the pressure
+of the foot operating against a lever.<span class="pagenum"><a name="Page_156" id="Page_156">[Pg 156]</a></span></p>
+
+<p>"I am going to rig up the cameras so we can
+take pictures of the explosions," said Alfred, as
+they made their way to the hangar.</p>
+
+<p>"That is a splendid idea," remarked the lieutenant.
+"Such an enterprise would be commended
+by the Intelligence Department of the
+War Office. By all means make the arrangements,
+for we expect to start in an hour."</p>
+
+<p>Alfred rushed over to the supply depot, and
+soon had the cameras in his possession, together
+with extra rolls of films. Ralph accompanied the
+lieutenant to the hangar to note the placing of the
+bombs.</p>
+
+<p>"Why are the bombs placed with the pointed
+ends up?" asked Ralph, as the men were placing
+them in position.</p>
+
+<p>"So the fulminate cap can be placed on, preparatory
+to launching," remarked the foreman.</p>
+
+<p>"Why, won't they go off without the cap on?
+Wouldn't a concussion explode them?" he asked.</p>
+
+<p>"Well, it would require a pretty tough jar to
+make them go off," replied the man.</p>
+
+<p>At the appointed time the eighteen machines
+arose, and started for the east. The sun was full
+in their faces, but the misty weather made it look
+like a great red ball, symbolic of the day's work.
+It was hard to get away from the glare of the sun
+as they arose to the height which the orders compelled
+them to take, and at Saarburg some of the
+machines were actually hit by missiles from the
+anti-airship guns.</p>
+
+<p>The first city of importance to greet their eyes,<span class="pagenum"><a name="Page_157" id="Page_157">[Pg 157]</a></span>
+after leaving Brumath, was Lauterbach, and then
+Karlsruhe, a city of over 100,000 was sighted.</p>
+
+<p>"We are now thirty-five miles from Ludwigshafen,"
+shouted the lieutenant, through the tube.
+"Keep well to the west of the river, and maintain
+the same height, until the city is reached."</p>
+
+<p>Two miles before Mannheim was reached eight
+of the machines swerved to the right, and crossed
+the river, their destination being the town of Oppau,
+several miles beyond the town, where large
+manufacturing establishments were turning out
+ammunition.</p>
+
+<p>"We are bound for the chemical factories," said
+the lieutenant. "See the workmen running about.
+They have, no doubt, heard of our mission by this
+time."</p>
+
+<p>"Which way shall I point the camera?" asked
+Alfred.</p>
+
+<p>"Straight down," replied the lieutenant. "I
+am going to signal No. 62 to take the lead, so we
+will be the fifth in line. That will give you a splendid
+opportunity to notice the effect of the explosions
+and to snap them."</p>
+
+<p>The lieutenant set the signal, "echelon formation,"
+which means step formation, one machine
+being ahead and a little to the right or to the left
+of the succeeding one. In that manner the ten
+machines flew along, the distance between them
+being about eight hundred feet, and by this arrangement
+each succeeding machine was able to
+observe the effect of the bomb dropped by the
+machine ahead.<span class="pagenum"><a name="Page_158" id="Page_158">[Pg 158]</a></span></p>
+
+<p>Mannheim was avoided, and the machines
+steered straight for the chemical headquarters on
+the left side of the stream where No. 62 released
+the first bomb. Alfred strained his eyes, and saw
+a flash below. It missed a building, and he shouted
+the information to Ralph through the tube.</p>
+
+<p>"If that had gone a hundred feet to the right it
+would have taken a dandy building,&mdash;there, the
+second shot did it; that came from old Spic's machine;
+whew-w-w, but look at it! That smoke is
+as black as coal,&mdash;must be lots of chemicals there.
+Another,&mdash;and the second building smashed to
+flinders. The lieutenant is going to drop the first
+one,&mdash;down she goes! I took two fine ones just
+now. I'll bet the last picture will show it up just
+as it happened. Two more snaps. We are going
+to turn and go back. 62 is making the circle."
+Thus Alfred graphically described the first trip
+over the doomed town.</p>
+
+<p>A dense cloud was now coming up, or, rather,
+bunches of them in various places where the missiles
+struck, and just as the Seraph was making
+the turn a tremendous explosion was heard, which
+actually seemed to jar the machine. Alfred arose
+from his seat, and the lieutenant's tense face
+showed that something unusual had happened, as
+he gazed below. All the buildings were emptied
+and scores of operatives were lining up along the
+river bank, and moving toward the great bridge
+south of the works.</p>
+
+<p>"Did you notice that big explosion?" asked Alfred
+through the tube.<span class="pagenum"><a name="Page_159" id="Page_159">[Pg 159]</a></span></p>
+
+<p>Ralph nodded his head affirmatively.</p>
+
+<p>"That hit the largest building in the place, and
+there isn't much left of it. Did you see that tall
+chimney at the left side of the town? Well, that
+looks just like a big cannon with the smoke and fire
+coming out of it," commented Alfred.</p>
+
+<p>The ten ships crossed the town twice, discharging
+all their bombs, but they waited in the air for
+twenty-five minutes until the first of the detached
+airplanes from the north appeared. During this
+time there was plenty of opportunity to see the extent
+of the damage which had been done to the
+great factories.</p>
+
+<p>At a signal the airplanes, constituting the
+squadron, were lined up in two columns, and before
+they had proceeded far the signals told the
+success of that part of the squadron which had
+gone to Oppau. The signal was now set for
+"Home," and the machines, by this time lightened
+of their missiles, made a tremendous speed, until
+after they left the Rhine, and were making the last
+lap of the journey, when the machine carrying
+Captain De Goye and his Adjutant Buanau-Varilla,
+was forced to descend, owing to an accident.</p>
+
+<p>The different machines circled around, hoping
+to be able to render assistance, but shortly after
+the airplane landed it was discovered to be in
+flames, and it was conjectured that seeing relief
+was out of the question the aviators had destroyed
+the machine to prevent its being of any use to the
+enemy.</p>

+
+<h2><br />CHAPTER XIV</h2>
+
+<h2>A TERRIBLE FIGHT IN THE CLOUDS</h2>
+
+<p><br />The return to the base with only the single mishap
+alluded to was cause for congratulations, and
+the lieutenant came in for a large share of the
+commendation.</p>
+
+<p>In turn he prepared a special report setting
+forth the work done by the boys on the eventful
+journey. He pointed out that Ralph piloted the
+machine the entire distance, giving him, as the
+commanding officer of one division, time to direct
+the operation of the machines and attend to the
+bombs, while he had the pleasure of presenting to
+the authorities a set of unique photographs taken
+by Alfred at the very time the bombs were thrown
+and exploded.</p>
+
+<p>When the roll was called, two days thereafter,
+the men of the squadrons were lined up, an officer
+from headquarters passed down the line, and,
+among other places, halted before the boys, who
+stepped forward. On the breast of each was
+pinned a medal, and as the officer did so he kissed
+them on the cheeks, a custom which is faithfully
+observed, in accordance with the regulations,
+whenever a merit order is bestowed.<span class="pagenum"><a name="Page_161" id="Page_161">[Pg 161]</a></span></p>
+
+<p>There was a cheer as the two blushing boys
+stepped back to the line, and there were no
+prouder hearts than theirs as they heard the encomiums
+expressed on all sides for their bravery
+and devotion to duty. It was a pleasure to many
+other young Americans, who, like them, were volunteers
+serving in the aviation corps, and many
+of whom were afterwards also honored in like
+manner.</p>
+
+<p>There was hardly a day that there was not some
+experience added to their store of knowledge pertaining
+to airships, and the work connected with
+flying, all of which was performed with efficiency
+and credit.</p>
+
+<p>But the work which they performed was not all
+a series of jolly excursions without the corresponding
+sorrows. The devotion of Lieutenant
+Guyon to them dated from the time when that
+brave officer was stricken while on a trial flight
+from the camp at Bar-le-Duc. He never forgot
+how they took charge of the machine, and brought
+it safely to earth and cared for him so tenderly.
+Thereafter, it was rarely the case that he went
+aloft without one or both of the boys in his company.</p>
+
+<p>Shortly after the foregoing events, while the
+three were performing scout duty north of St.
+Mihiel, they were attacked by two German machines,
+an Albatross and a Taube, a combination
+which, especially when operating against a single
+machine, is capable of doing deadly work.</p>
+
+<p>When the two enemy ships were sighted, Alfred<span class="pagenum"><a name="Page_162" id="Page_162">[Pg 162]</a></span>
+was in the pilot's seat, and under the direction
+of the lieutenant, the airplane shot forward
+directly in the path of the first machine, while
+the lieutenant poured out a constant storm of shot.
+The Albatross dived, and Alfred at once moved
+the control to ascend, thus bringing their machine
+above the Taube.</p>
+
+<p>The object now was to so manoeuver their ship
+as to keep between the two enemies, and in doing
+so make it difficult for either of them to use the
+quick firers without danger of hitting the other.
+The Seraph was a rapid climber, due to the high
+power of her engines.</p>
+
+<p>"Send her up as rapidly as possible," shouted
+the lieutenant. "Keep on going, and turn slowly
+to the left, so as to make a big circle; that will
+give me a chance to put in some shots."</p>
+
+<p>Alfred knew the manoeuver, the purpose being
+to bring the two machines into line with each
+other, and thus enable the lieutenant to get his
+gun in the range of both machines.</p>
+
+<p>"A little down now, and more to the right;
+there, steady," was the next command.</p>
+
+<p>"Br-r-r-r-r" sounded the gun, as the officer
+turned the crank.</p>
+
+<p>"The Taube is going down," cried Ralph excitedly,
+"and here comes another of the same
+kind," continued Ralph.</p>
+
+<p>"Go straight for the second one," shouted the
+lieutenant, and Alfred knew that the same trick
+had to be repeated.</p>
+
+<p>But the new arrival did not accept the invitation<span class="pagenum"><a name="Page_163" id="Page_163">[Pg 163]</a></span>
+to fight on the lines that the first machine
+adopted. Instead, it began to circle about at a
+safe distance, endeavoring to secure the overhead
+position.</p>
+
+<p>"Follow that bird," said the lieutenant, "and
+keep going. They will learn something about high
+flying before they get through with us."</p>
+
+<p>The Albatross was not making much headway
+in the climbing game. On the other hand, the new
+Taube was an extraordinary flyer.</p>
+
+<p>"There is only one man aboard of her," said
+the lieutenant. "Take the glasses, and see if you
+can make out her number."</p>
+
+<p>Ralph studied the machine for some time. "I
+am not sure," he said, "but I think it is D 28. No
+one but the pilot is aboard."</p>
+
+<p>"That's good. He can't hit us head on. Trail
+him or get ahead of him and keep on ascending,"
+said the lieutenant, now preparing his rapid firer
+with a new charge.</p>
+
+<p>The Taube suddenly swerved to the right, and
+let loose a full charge from his gun. It seemed
+as though one side of the Seraph had the covering
+of the planes ripped off, for the hail of bullets tore
+right through the frame. Alfred shook his head
+as he cleared away several bits of wreckage.</p>
+
+<p>"How high are we?" asked Ralph.</p>
+
+<p>"Two thousand six hundred meters," was the
+reply.</p>
+
+<p>The lieutenant had his revenge, however, for
+their own machine was now creeping up and gradually
+getting a rear position. This was what he<span class="pagenum"><a name="Page_164" id="Page_164">[Pg 164]</a></span>
+had been aiming for. The stream of shots from
+the Seraph's gun now began to tell. In one despairing
+attempt the Taube turned fully half way
+around and answered, but it was evident that
+something was wrong with the ship.</p>
+
+<p>Suddenly the Seraph darted down. Ralph and
+the lieutenant looked back in surprise. Alfred's
+head had dropped to one side, and one arm hung
+over the side of the chassis.</p>
+
+<p>The lieutenant leaned over and caught the elevating
+rudder, not a moment too soon, and corrected
+the machine. Ralph leaned over the side
+of the body, and drew Alfred toward him, as the
+lieutenant climbed into the aviator's seat. All
+this took but a moment's time, but meanwhile it
+was necessary for them to observe the enemy and
+avoid him.</p>
+
+<p>"The Taube is falling," cried out Ralph, "but
+the Albatross is swinging around."</p>
+
+<p>Before it was possible to correct the machine,
+and avoid the danger, the gunner of the oncoming
+aeroplane began to pump, and the shot began to
+tell on the Seraph's framework. The lieutenant
+now saw that it would be a terrific task to get
+above the Albatross, so turning the control rudder
+sharply, the Seraph made a quick slide below
+its adversary.</p>
+
+<p>Alfred did not move, and Ralph tried to control
+himself, for in the great excitement attending the
+above circumstances, he was almost distracted.
+He was leaning partly over the body of the machine
+when the lieutenant saw him crouch forward.<span class="pagenum"><a name="Page_165" id="Page_165">[Pg 165]</a></span>
+He put his hand on the boy and tried to shake him,
+but there was no response.</p>
+
+<p>Down, down went the machine, still under absolute
+control of the lieutenant, who turned the
+machine in a circle in order to be sure to bring
+it down within the French lines. When within
+five hundred feet of the earth something seemed
+to go wrong with the steering mechanism. The
+lieutenant tugged and pulled the lever back and
+forth. The machine refused to move forward in
+a straight line, and landing while the machine is
+describing a circular movement is a most dangerous
+manoeuver.</p>
+
+<p>Both boys were quiet, and the lieutenant feared
+for the worst. A hundred feet more and all would
+be over. In desperation he banked the machine
+to stop its terrific speed. This helped the situation,
+but did not prevent the spinning motion, and
+finally the crash came.</p>
+
+<p>They landed in a newly ploughed field, the worst
+possible sort of place for a disabled machine.
+The lieutenant and Ralph were thrown out of their
+seats, but Alfred was held fast in the machine.</p>
+
+<p>Many willing helpers were on hand, and they
+found all three of the flyers were unconscious
+when put into the van, but, fortunately, they were
+within a half mile of the emergency hospital south
+of St. Mihiel. On the way to the hospital a hurried
+survey was made to ascertain the extent of the injuries,
+but the physicians were silent.</p>
+
+<p>Alfred regained consciousness before the hospital
+was reached. The doctors said that there<span class="pagenum"><a name="Page_166" id="Page_166">[Pg 166]</a></span>
+was a severe bruise on the back of his head, as
+though he had been struck by some heavy object.
+The lieutenant opened his eyes, as he was placed
+on the operating cot. He glanced around wildly
+for a moment, and then asked: "Where are my
+boys!"</p>
+
+<p>"We have them here; they are all right," said
+a nurse.</p>
+
+<p>He forced a weak smile, turned his head to one
+side, and was quiet.</p>
+
+<p>Ralph had been shot through the body, too high
+up, it was believed, to touch the lungs. A second
+bullet had passed through the fleshy part of the
+left arm, and he was very weak from loss of blood.
+The three were placed on adjoining cots after
+the first examination was over, and after all had
+regained their normal senses a pair of stretcher
+bearers entered the door, and bore a wounded man
+to one of the adjoining cots.</p>
+
+<p>The lieutenant was the first to observe the chevrons
+on the sleeve of the patient, and that he was
+a German. Ralph tried to raise up as he noticed
+them carefully lift the wounded man, and deposit
+him on the cot.</p>
+
+<p>"That's the fellow who piloted the last Taube;
+I'm sure of that. He's the fellow I saw through
+the glasses," said Ralph.</p>
+
+<p>Inquiry quickly established the truth of Ralph's
+observation. His machine had fallen within
+French lines, and not far from the place where
+the Seraph struck. It was an odd coincidence.</p>
+
+<p>The lieutenant was the most severely injured,<span class="pagenum"><a name="Page_167" id="Page_167">[Pg 167]</a></span>
+how badly no one knew at the time, for a certain
+time must elapse before the full extent of the injury
+in such cases develops. The next morning
+the boys were informed that the lieutenant was
+much worse, and then for two days they had no
+news.</p>
+
+<p>Meanwhile, Ralph's wounds were healing, and
+no excessive fever developed. Alfred's spine
+seemed to be affected by the terrific blow, but that
+would be all right again in course of time.</p>
+
+<p>The sad intelligence came to them a few days
+thereafter that the lieutenant had died. It was, indeed,
+a grief to them. They had grown to love
+him as a friend, and they understood each other
+so well. It was learned that his heart was too
+weak to bear up against the internal injuries,
+which he received when the machine struck the
+earth.</p>
+
+<p>It was two weeks before the boys were able to
+leave the hospital, and they were then not able
+to return to duty. The shock of their friend's
+death was so acute that, as Ralph expressed it,
+they never again wanted to see an airplane.</p>
+
+<p>They were soon sent to Paris to recuperate, and
+while there they formed plans which took them
+into another part of the great war game, and we
+may be able hereafter to follow them in their new
+exploits.</p>

+<p><b>The Hilltop Boys; A Story of School Life</b></p>
+
+<p>Jack Sheldon, a clean-minded and popular student in the academy,
+gains the enmity of several of the boys, but their efforts to injure him
+fail. A mystery, connected with Jack's earlier life, is used against
+him, but he comes off with flying colors.</p>
+
+
+<p><b>The Hilltop Boys in Camp; or, The Rebellion at the Academy</b></p>
+
+<p>A strange situation arises in which an airship figures as the bearer
+of an important letter. The head-master acts without investigating all
+the facts, but matters are all finally adjusted to the satisfaction of all
+concerned.</p>
+
+
+<p><b>The Hilltop Boys on Lost Island; or, An Unusual Adventure</b></p>
+
+<p>The scene now shifts to the West Indies and Jack figures as the
+hero of a daring rescue. Their experiences in tropical waters form a
+most stirring narrative, and the young reader is assured of a tale of
+gripping interest from first to last.</p>
+
+
+<p><b>The Hilltop Boys on the River; or, The Cruise Up the Hudson</b></p>
+
+<p>The Doctor takes a number of the boys on a cruise up the Hudson.
+An unlooked-for incident finds Jack Sheldon equal to the occasion, and

+was turned into a complete victory for our young friends.</p>
+
+
+<p><b>The Hilltop Boys Doing Their Bit; or, The Young
+Farmers of the Highlands</b></p>
+
+<p>Our young friends, fired with patriotism, prove their real worth to

+
+<p><br /><b>The Boy Volunteers on the Belgian Front</b></p>
+
+<p>Describes the adventures of two American boys who were in Europe
+when the great war commenced. Their enlistment with Belgian
+troops and their remarkable experiences are based upon actual
+occurrences and the book is replete with line drawings of fighting
+machines, air planes and maps of places where the most important
+battles took place and of other matters of interest.</p>
+
+<p><br /><b>The Boy Volunteers with the French Airmen</b></p>
+
+<p>This book relates the further adventures of the young Americans in
+France, where they viewed the fighting from above the firing lines.
+From this book the reader gains considerable knowledge of the
+different types of air planes and battle planes used by the warring
+nations, as all descriptions are illustrated with unusually clear line
+drawings.</p>
+
+<p><br /><b>The Boy Volunteers with the British Artillery</b></p>
+
+<p>How many boys today know anything about the great guns now
+being used on so many European battle fronts? Our young friends
+had the rare opportunity of witnessing, at first hand, a number
+of these terrific duels, and the story which is most fascinatingly
+told is illustrated with numerous drawings of the British, French
+and German field pieces.</p>
+
+<p><br /><b>The Boy Volunteers with the Submarine Fleet</b></p>
+
+<p>Our young heroes little expected to be favored with so rare an experience
+as a trip under the sea in one of the great submarines. In
+this book the author accurately describes the submarine in action,
+and the many interesting features of this efficient fighting craft
+are made clear to the reader by a series of splendid line drawings.</p>
+
+<p><br /><b>The Boy Volunteers with the American Infantry</b></p>
+
+<p>The entry of the United States into the great conflict offers the
+two boys their long-looked-for opportunity. The arrival of our
+troops abroad and the boys' experiences with them make a thrilling
+tale.</p>

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.

+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate

+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:

+
+ANTWERP AND THE FLIGHT THROUGH NORTHERN BELGIUM
+
+
+Antwerp was in a fever of excitement, as Ralph and Alfred marched up
+from the quay with the Belgian troops, and rumors of an immediate attack
+on the city were flying about.
+
+"Look at the Zeppelin!" cried out a voice.
+
+The boys turned to follow the gaze of the people who lined the streets.
+There, almost directly west, they caught the first glimpse of one of the
+monsters which appeared to be moving south, far beyond the reach of the
+encircling forts, but plainly visible.
+
+"Nothing would suit me better than a trip in a flying machine!"
+exclaimed Alfred.
+
+"Wouldn't that be fine?" replied Ralph.
+
+The sight seemed to be an inspiration to the boys. Our story will tell
+how the idea so impressed itself on their minds that they almost felt
+it a duty to join a flying corps. That, however, seemed to be an
+impossibility.
+
+They had passed through Belgium, participated in the first battles of
+the war, had been captured, and escaped from the Germans, and had now
+reached Antwerp, with the retreating Belgian army, where Ralph had hoped
+to meet his father, whom they had left in Germany almost four weeks
+prior to that time.
+
+As the father had not arrived, owing to the embargo which had been
+placed on all travelers from Germany to the warring countries, the boys
+found themselves stranded in a strange city. Fortunately, their
+connection with the army, and the fact that they had rendered Belgium
+some service, made it possible for them to get food and lodging.
+
+"We have forgotten one thing," said Ralph.
+
+"What is that?" inquired Alfred.
+
+"Why, we never went to the Post Office," replied Ralph.
+
+At the General Post Office they received a letter from Alfred's father,
+only to learn that he had been detained, as was the case with thousands
+of Americans, and that it would be impossible for him to reach Antwerp.
+Instead, he would be permitted to go through Switzerland, and from that
+country reach Paris where he hoped to meet them.
+
+"But we have no money now, what shall we do?" asked Alfred.
+
+"That's what worries me," answered Ralph. "Father supposes that Pierre
+is still with us, and that we are supplied with money."
+
+Three days after receiving the letter the boys heard the first definite
+news of the great movement of German troops designed to attack the
+forts. If they surrounded the city, and besieged it, the chances of
+reaching Paris would be small, indeed.
+
+"Something must be done, and that today," said Ralph. "I am going to
+leave if I have to walk."
+
+"Where to?" asked Alfred.
+
+Ralph smiled, as he said: "We might walk to Holland."
+
+Alfred almost shouted for joy, as he exclaimed: "That's a good idea. We
+have about ten francs left; that ought to take us through."
+
+A map was consulted. "Why, yes," said Alfred, "we can go north to
+Eeckeren, and from that place to Capellen, close to the frontier. It's
+only twelve miles."
+
+After this decision they again visited the Post Office, and immediately
+crossed through the city with a view of striking the main highway
+leading to Holland. Reaching the outskirts of the city, they were
+surprised to see great masses of Belgian troops encamped close to the
+forts, which guarded the highway. They soon learned that a strong German
+column had reached Brasscheat, three miles from Eeckeren.
+
+They looked at each other in amazement. "Well, this beats everything,"
+said Alfred, with a shade of bitterness. "The Germans seem to be in our
+way whichever direction we turn. We'll have to take another route."
+
+"Another route?" blurted out Ralph. "There isn't another way to go on
+this side of the river. It would be a long tramp to cross the river."
+
+They were now in a serious dilemma, and stood there undecided as to the
+best course to follow, when they were startled by a voice: "Hello,
+boys!"
+
+"It's Pierre!" shouted Alfred, who was the first to spy their friend.
+
+"And how did you get here?" asked Alfred. "We thought they had captured
+you at Rouen."
+
+"So they did, but we got away the same night. But where are you going?"
+returned Pierre.
+
+"Trying to get to Holland," he was informed.
+
+"I am afraid you will have to go south of the Scheldt to get there,"
+Pierre then informed them.
+
+"But I received a letter from father, and he wants us to meet him in
+Paris," said Alfred. "You know we don't want to be shut up in the city,
+if the Germans are going to surround it."
+
+"Of course not," answered Pierre. "But in the meantime we must find some
+other way out. You know you are still in the army, in the messenger
+service, and come to think of it, you haven't received any pay so far,
+have you?"
+
+The boys laughed, for that part of it had been entirely forgotten.
+
+"Why, yes; the Germans paid us for work at the hospital," said Ralph.
+
+"And you repaid them by skipping out the next day," said Pierre with a
+smile.
+
+"How much do you think there is due us now?" asked Alfred.
+
+"I don't know what you are on the rolls for, but there must be a full
+month's pay due, and that would be about thirty-five francs apiece,"
+said Pierre.
+
+"Thirty-five francs!" mused Ralph. "Twice thirty-five is seventy,--about
+fourteen dollars. Good, that will take us through."
+
+"I suggest that you come to headquarters and join us. We intend to cross
+the river. It will be the safest place for you," said Pierre.
+
+"That will suit me," said Ralph.
+
+Together they marched to headquarters where they were again installed
+and placed on the rolls. Late that night the regiment began its march,
+reaching the dock below Antwerp at ten o'clock, where they had a long
+wait before the crowded boats left the pier. On landing, the march was
+resumed, and did not halt for two hours, so it was nearly three in the
+morning before they were able to lie down for the much needed sleep.
+
+It did not seem that they had slept a half hour when they were awakened
+by the heavy booming notes of cannon, and the occasional rattle and
+crash of small guns. The boys now knew the kind of music which the
+different weapons ground out.
+
+"That's a machine gun, see how regularly the shots come," said Alfred.
+
+"Yes; and that's a salvo from infantry," replied Ralph. "The Mannlicher
+guns have an awfully snappy way of talking. Do you hear it? There it is
+again. They must be rushing some of the outer works."
+
+The real fight, however, was between the forts and the heavy German
+guns, which continued during the entire day, principally on the southern
+and eastern sides of the city. The struggle was continuous for four
+days. Suddenly Pierre burst in with the startling information:
+
+"The Germans have silenced two of the forts, and Antwerp is doomed."
+
+No time was lost by the defending troops, and before noon the camp was
+dismantled, and the march begun.
+
+"Do you know where we are going!" asked Alfred.
+
+"Nothing more than that we are going to leave Antwerp, and try to reach
+the sea," replied Pierre.
+
+The Belgian army had begun its famous march across the northern end of
+Belgium in order to reach the sea, and secure the protection of the
+English fleet in the Channel.
+
+"I heard some one say that we intended going through Bruges," said
+Ralph.
+
+"Yes; and from there the army may be able to reach France, after passing
+through Ostend," said Pierre.
+
+In an air line Bruges is fifty miles from Antwerp, and from Bruges to
+the French frontier it is fully forty miles more. How the brave little
+army finally reached its destination, avoiding the large German forces
+sent out to intercept them, remains one of the most glorious exploits
+in the history of the Belgian army.
+
+"Next to Belgium I am glad to be in France," said Pierre. "Now you can
+get to Paris without difficulty," he added.
+
+It thus happened that six weeks after the boys entered Belgium southwest
+of Liege, they reached Dunkirk on the French coast, and saw the immense
+fleet of warships and transports, which the British had in the harbor.
+It seemed that every spot around the city was taken up by tents, wagons,
+mules, horses, and heavy guns, to say nothing of the soldiers on every
+hand.
+
+One regiment after the other entrained in cars, and were whirled to the
+south. Box cars, flat cars, some new, others dilapidated, were in
+service. It seemed that there were thousands of automobiles in line, and
+every one was anxious to get away. They even saw thousands of men, with
+full kits on their backs, march out to the east, as though they scorned
+to wait for railway or auto accommodations.
+
+Pierre was at the door of the boys' tent early in the morning of the
+second day. "I am glad to tell you that the roll has been signed, and
+you can get your pay," he said. "But I am awfully sorry to have you go."
+
+"Of course, we've had some pretty hard times," said Ralph, "but it was a
+great experience. Maybe we'll come back again."
+
+"We're going to try to join the flying machines," said Alfred.
+
+Pierre laughed, and Ralph smiled, for, while that idea was uppermost in
+his mind, he had never discussed the subject with Alfred sufficiently to
+enable them to call it a plan that they really intended to follow out.
+It was more an enthusiastic feeling of something that they would like to
+do, without knowing just how they would go about it.
+
+"So you are really going to start for Paris this afternoon?" said
+Pierre.
+
+"Yes; we ought to be there now, for father will wonder what is the
+matter with us. You see he hasn't heard from us for six weeks, and it
+has been two weeks since we received his letter," said Ralph.
+
+"Then why don't you wire the Continental Hotel, Paris, and tell him you
+are on the way? It will relieve his anxiety. Tell him to answer you at
+once, for it may take you several days to reach Paris," said Pierre.
+
+"Several days?" queried Alfred.
+
+"Yes, indeed. Troops occupy all the cars now," replied Pierre.
+
+So the telegram was sent, and it was decided to remain where they were
+until morning so as to receive the reply before starting. But no answer
+came that night or the next day. In the meantime, the boys wandered from
+place to place, for, as they still wore the trim Belgian suits, they
+were privileged to visit many places barred from civilians.
+
+In the afternoon they found themselves far down the road leading to
+Ypres, when they were startled at the sound of an unusual buzzing, and
+soon divined the cause as they saw a dozen or more airplanes flying
+around over the broad fields to the east. Nothing more was needed to
+give the boys an inspiration. They moved toward the great field, as
+though a giant magnet pulled them. Long before they were near the
+hangars they could see the flyers far above them, circling about. The
+scene fascinated them.
+
+Then something like a dull explosion startled them, and they looked at
+each other and then glanced about.
+
+"There it is; look at it; directly above us," shouted Alfred, in great
+excitement.
+
+"Something has happened; it's on fire," said Ralph.
+
+In an incredibly short space of time, something struck and rattled along
+the ground not far from them, but the machine, although falling, was
+still some hundreds of feet from the earth. One of the operators could
+be seen frantically drawing back the levers, and trying to hold the
+badly damaged ship from overturning, but his efforts were unavailing.
+
+The boys closed their eyes as the swiftly moving machine now actually
+rolled down through space, tumbling over and over, until it finally
+struck the ground with a crashing noise, not a hundred feet from where
+they stood. Terrorized at the sight, they stood still for a few moments,
+but this was no worse than the scenes they had witnessed in battle, so,
+without a word, they made a rush for the mound of debris.
+
+"They are both under the machine," said Alfred.
+
+"Look at the smoke; it's afire," shouted Ralph.
+
+"Use sand! use sand!" almost shrieked Alfred.
+
+They had early learned that sand is more effectual as a fire
+extinguisher of burning oil than water, if properly applied. Handsful of
+sand were scooped up and applied. A groan from one of the men arrested
+their movements.
+
+Alfred jumped on the broken mass, and peered down. "There he is!" he
+shouted. Ralph crawled over the broken body of the airplane, and reached
+down.
+
+"No; this man is lying still," he said. "Here he is; come on this side;
+he is under the framework."
+
+The scene was one which well might inspire heroic work.
+
+The imprisoned man was quite young, with handsome features, and it
+seemed cruel that such a fate should overtake him. The boys strained at
+the wreck until it moved.
+
+"Brace it up on that side," said Ralph.
+
+The truss from the fuselage was removed from the aviator, the man
+quickly drawn out from his perilous position, and carried clear of the
+wreck.
+
+"Now for the other one," said Alfred.
+
+Blood was still flowing across the face of the other flyer, as they
+crawled over the wreck to draw him out.
+
+"This one is alive, I am sure," said Ralph.
+
+"Why, yes; his heart is beating," replied Alfred, as the injured men
+were laid side by side.
+
+"I have heard that they have first aid packages in machines of this
+kind," said Ralph, as he sprang toward the remains of the machine. "I
+have it," he cried, as he leaped over the wrecked pieces. "Here
+is--a--_Restorative_, whatever that is,--half a wineglass at a
+time,--where's the wineglass?"
+
+"Give each a good swallow of it," said Alfred, as he raised up the head
+of the one first rescued.
+
+The other man opened his eyes. "Lieutenant!" he said. Then, as he gazed
+at the boys, he seemed to smile, and as Alfred held up the bottle he
+feebly nodded.
+
+It seemed to revive him in a few moments, and he struggled to raise
+himself. "I feel better now, but something hurts my legs," he said.
+
+The lieutenant opened his eyes, and quietly looked at the boys without
+speaking.
+
+"Can I do anything for you?" said Alfred.
+
+"Is Jack hurt?" he asked.
+
+"Yes; but he is all right," said Ralph.
+
+"Here I am; still on top," said Jack, as he slightly turned, and moved
+his hand toward the lieutenant.
+
+"And what are you boys doing here?" asked the lieutenant.
+
+"On our way to Paris," said Alfred.
+
+"But where did you get the uniforms?" asked the officer.
+
+"Why, we've been in the Belgian army, and were in several fights," said
+Ralph proudly.
+
+The lieutenant's face brightened into a smile, which quickly changed to
+one of pain. An ambulance stopped alongside with startling suddenness,
+for the boys had been too busy to notice that the watchers at the
+hangars had signaled for assistance. The men were carefully carried to
+the van, and as they were about to start the lieutenant motioned to the
+doctor in charge, and said:
+
+"I want the boys to come along with us."
+
+
+
+
+CHAPTER II
+
+IN THE AVIATION CAMP
+
+
+Once inside the ambulance the boys had an opportunity to watch the
+doctors, as they removed the clothing from the men, and began a search
+for the location and nature of the injuries. It was a gratification to
+be able to assist in this work. Jack's legs were both broken, and the
+lieutenant's chest, back and right arm were bruised and clotted with
+blood.
+
+"I think they are all right," said the doctor in charge.
+
+"But it's awfully hard breathing," said the lieutenant.
+
+"You must have had a pretty good weight on top of you," remarked the
+doctor.
+
+"I should think so," said Ralph. "It was all we could do to lift up the
+cross piece of the frame from him."
+
+"We'll straighten you out in a few days," answered the doctor, "but your
+companion didn't fare as well. Compound fracture of one leg; but he has
+a good constitution; he's good for several trips yet."
+
+The gratitude of the lieutenant was plainly observable, and the doctor
+was quick to notice it. "If these young men hadn't taken you out when
+they did it would have been all over with you, because the weight
+prevented you from breathing."
+
+The lieutenant tried to smile, as he gazed at the boys, and they
+understood.
+
+When the ambulance reached the hospital there were fifty or more
+aviators from the station, awaiting the news. The boys leaped out, the
+attendants were on hand with the stretchers, while the excited men
+crowded around the boys to learn the details. It was not long before the
+story of the rescue was known. The chief of the flying squadron came out
+of the hospital, and approached the boys. The latter straightened up and
+saluted.
+
+"You should be commended for the prompt work you performed in rescuing
+the lieutenant and his pilot. I understand you belong to the Belgian
+army; but you are not Belgians, are you?" he asked.
+
+"No, we are not," said Alfred, slightly embarrassed at the question.
+
+The Commandant smiled as he continued: "I take it that you are
+Americans?"
+
+"Yes, Captain; you are right," replied Ralph. "We joined the Belgian
+army at Liege, and fought the enemy all the way to Antwerp, and we had
+some pretty hot times, too."
+
+This speech was applauded heartily, while a young man sprang forward,
+held out his hand and said: "And here's United States, too."
+
+"We are not with the army now," said Alfred, recovering; "we hope to go
+to Paris, if it is possible to get there."
+
+"The chances for that are not very good at present," observed the
+Commandant, "but in the meantime, if you are not attached, you must put
+up with us."
+
+"Thank you for the offer," said Ralph eagerly. "We want to get into the
+flying service; that will just suit us."
+
+"I am afraid that the army provisions would not permit you to join,"
+said the officer, and all noted the expressions of disappointment that
+indicated the boys' feelings at this announcement.
+
+"Then I suppose we'll have to force our way in, just as we did in
+Belgium," said Alfred.
+
+This was greeted with a sally of laughter. The boys had made a hit with
+the corps, and they accepted the offer of quarters for their
+accommodation in the firm belief that something would turn up to assist
+them in their desires.
+
+Boys are really at a disadvantage sometimes. This story, as well as many
+others, shows that they are capable of doing things as well as men, and
+that they can do some things better than most men; but in military
+matters the service seems to have been made for grown-up people on the
+principle that war is too barbarous a thing for young men until they are
+twenty years of age.
+
+The boys, who were now in their glory, had a portion of a small room in
+a wooden building assigned to them. At this time there were fifty
+machines of various types on the ground, the particular makes being
+the Bristol, the B. E., several Farman machines, and a half dozen
+Sopworth tractors.
+
+Tom Walton, the young American who greeted them at the hospital, was
+accorded the privilege of escorting the boys and introducing them. That
+they had been in the first battles of the war was sufficient to give
+them a coveted place in that company of enthusiastic men, for there was
+some glory in having been on a battlefield,--a thing which could have
+been said of only a few of those who entertained them that day.
+
+"I suppose you want to see the machines," said Tom.
+
+"Indeed, we do," said Alfred. "What is that big machine over there?"
+
+"That is a Bristol," answered Tom.
+
+"And there is another one," remarked Ralph, pointing to a machine, which
+was being drawn out of the hangar.
+
+"No, that's a B. E. biplane," answered Tom. "You will see the difference
+by observing the shape of the planes. The Bristol has the ends of the
+wings rounded so that the forward corners are cut away to a greater
+extent than the rear corners. In the B. E. the wings are cut to conform
+with the well-known Wright type."
+
+"That's a Farman machine, I know," said Ralph, pointing to an aeroplane
+which had a huge revolving type of motor forward of the main planes.
+
+"Yes; but when that machine is high in the air it would be difficult to
+recognize it from that description," said Tom. "You will notice that the
+lower plane is much shorter than the upper plane, and that it has a
+great spreading tail,--larger than any other machine now made."
+
+[Illustration: _Types of Allied Airplanes_]
+
+"Here is another kind, a little fellow. That certainly looks different
+from all the others," said Alfred, as they stopped in front of a hangar.
+
+"That's the Sopworth tractor, a fine, speedy machine, with square ends
+to the planes, and a heart-shaped tail. It can be distinguished at any
+altitude," answered Tom.
+
+"I notice that that has different tails," said Ralph. "Does that make
+any difference in the flying?"
+
+"Not in the least. Shape has nothing to do with it. Surface is all that
+counts. They are made with distinctive forms so that they may be easily
+distinguished, one from the other."
+
+"We saw some German airplanes, several dozens of them, in Belgium, and
+the only one I could recognize was the Taube, as they called it. They
+have fan-shaped tails," said Alfred.
+
+"But here is the machine for business," said Tom, as they halted in
+front of a gaily decorated hangar, and pointed to a trim little machine,
+which was being overhauled.
+
+"I see you have the Stars and Stripes above the door," said Ralph.
+
+"Yes; and this is my machine; isn't it a beauty?" said Tom with a
+considerable show of pride.
+
+"What is it? I mean what make?" asked Alfred.
+
+"It is a French Morane; I have made many trips in it," said Tom, "and
+now I am going to use it against the Dutchies."
+
+Thus they were conducted from place to place, visited the machine shop,
+which had been set up for repairs, and then inspected the landing field,
+which was designed to be illuminated for night work.
+
+"Do you mean to say that you use the flying machines at night?" asked
+Ralph.
+
+"Why, certainly; that is going to be a great stunt," said Tom. "The only
+trouble is that where there are many lights about it is pretty hard for
+a pilot to hunt out the landing place, so the authorities have made
+special provision for returning aviators to enable them to land with as
+much safety as in the daytime."
+
+"How is it arranged so they can land without a mistake?" asked Alfred.
+
+[Illustration: _Airplanes of the Central Powers_]
+
+"Do you see that tall pylon, over there?" replied Tom. "That has on it
+the pilot light, much more brilliant than anything in sight. Now, look
+over to the left, nearly a quarter of a mile away; that pylon carries a
+brilliant red light. The other two pylons to the north and to the south
+have blue lights. The aviator knows that the bright light is to the east
+of the red light, and that he must make a landing somewhere between the
+brilliant light and the red light, between the limits marked by the blue
+lights."
+
+"I should think that would be easy," said Ralph.
+
+"It is when the night is clear; but the trouble is that the fog from the
+channel gives us considerable trouble, and then we have to glide back
+and forth very low to get our bearings, and that is dangerous business
+in the night."
+
+The inspection raised the enthusiasm of the boys to the highest pitch.
+For them there was now no other life than flying, and, indeed, things
+seemed to be coming their way. They had learned more about machines
+during the two hours thus spent than they had acquired in all their
+lives previous to that time.
+
+"I want to ask a favor of you," said Alfred, as they were returning to
+their quarters.
+
+"Go ahead," said Tom.
+
+"I would like to go up in a machine with you," was the reply.
+
+Tom stopped, and looked at Alfred. "Do you really mean it?" he asked.
+
+"Of course I do," replied Alfred.
+
+"That's what I want to do, too," chimed in Ralph.
+
+"It's against the rules to take up any one but the observers during
+practice hours; but let me see,--we may be able to fix it up some other
+time," said Tom.
+
+"Do you have to do much practicing?" asked Alfred.
+
+"Only from six to eight hours a day," answered Tom.
+
+"What! do you mean practice flying when you are not scouting?" asked
+Ralph.
+
+"Well, I should say so," was the answer.
+
+"How long have you been flying?" asked Ralph.
+
+"About two years," said Tom.
+
+"And still they make you fly every day, for practice?" asked Alfred.
+
+"Of course," said Tom.
+
+"And what is that for?" asked Alfred.
+
+"Flying airplanes for war purposes is something different to ordinary
+flying. The principal practice is to learn the methods of attack and
+defense. But that is not all. The airplane is the eye of the army; the
+observer must know how to observe. He must be able not only to see, but
+to put his knowledge into such form that it can be handed in in the form
+of a report. While he may get the information he must learn that the
+information is not for his own gratification, but for the use of the men
+in the field," said Tom.
+
+"Do all the machines carry a pilot and an observer?" asked Ralph.
+
+"Not by any means," answered Tom. "The first duty of a pilot is to learn
+how to control his machine when approaching an enemy, and how to attack
+or to avoid him. For that purpose he has a machine gun which he uses in
+flying."
+
+"I had no idea that there was so much to do in the business," said
+Alfred.
+
+"That is only part of the practice," continued Tom. "The most
+interesting part of the work is to practice flying in squadron
+formation, to observe the signals of the commanding officer and to
+execute movements. For this purpose two squadrons oppose each other, and
+sally forth, the object being to judge the objects of an attacking force
+and to devise means to repel the enemy."
+
+The boys sat on their improvised bunks until a late hour that night.
+They discussed the airplanes; the men they had met; their work in
+rescuing the fallen aviators, and the things they had learned in this,
+to them, the most eventful day.
+
+"I wonder what father would say if he knew we were going to join the
+aviation corps?" said Alfred.
+
+"Well, I wonder what he will say when he hears what we were doing in
+Belgium," replied Alfred.
+
+"He must have gotten our letters by this time," said Ralph.
+
+"Then why doesn't he answer our telegram?" asked Alfred.
+
+"Why, we forgot to go back to the city and inquire for it," said Ralph.
+
+"That's so; but we've been too busy for that; we must do that the first
+thing in the morning," said Alfred.
+
+
+
+
+CHAPTER III
+
+THE WOUNDED AVIATORS
+
+
+They were out early the next morning, and started for the tramway a mile
+distant. They passed Tom's hangar, and stopped for a moment to take a
+look at his machine. As they were leaving they heard his voice:
+
+"Going to leave us?" he inquired.
+
+"No; but we must go to the city to get our mail, and we are expecting a
+telegram," shouted Ralph.
+
+"Get back by eleven o'clock if you can," was the answer.
+
+"We'll be here, sure," said Alfred.
+
+"He must mean that we can have a try in the machine at that time, I
+suppose," remarked Ralph.
+
+"I imagine that's why he wants us back then," answered Alfred.
+
+They covered the mile in record time. The idea of going up in a machine
+was a stimulus, and they talked about it all the way, and wondered what
+it would feel like to sail above the earth in a war-machine.
+
+At the post office they had their first disappointment, and there was
+nothing at the telegraph office. They were perplexed at the absence of
+news, but consoled themselves with the thought that transportation from
+the Swiss frontier might be in the same condition as at the Western
+front, so they decided they would not remain long in the city.
+
+The city, containing a population of about 40,000, is located on the
+sand dunes. It takes its name from the old church of St. Eloi, and means
+_church on the dunes_. It has been in existence for over a thousand
+years, and was owned by the Dutch, the Spaniards, and the English,
+before it became permanent French territory.
+
+Passing through the principal square, on their way to the terminus of
+the tram cars, they saw crowds of people moving toward the main landing
+place of vessels. They followed, and witnessed the debarkation of the
+first vessel load of Red Cross supplies, accompanied by a large corps of
+physicians and Red Cross nurses.
+
+Fully fifty vans were taken from the ship and lined up, with their
+equipments, ready for a prompt start. A number of lorries (large motor
+trucks), carrying beds, bedding and like material, followed, and were
+placed behind the vans.
+
+"Do you know where they are going?" asked Ralph, addressing a young man
+in uniform.
+
+"To the general hospital, where they will be assigned to stations near
+the front," he replied.
+
+"Do you mean the general hospital near the aviation ground?" inquired
+Alfred.
+
+"Yes," was the answer.
+
+"Probably we can get a chance to ride there," said Ralph, addressing
+Alfred.
+
+The man overheard the remark, and quickly turned to the boys.
+
+"Are you attached to the flying squadron?" he asked.
+
+"Yes," replied Alfred.
+
+"Then they wouldn't object, I am sure," answered the officer, and he
+strode forward. After speaking a few words to one who seemed to be in
+charge, he motioned to them.
+
+"Get in, boys," he said.
+
+They were quick to respond, and, after thanking the officer, mounted one
+of the vans. Inside were three nurses and two physicians, who smiled at
+the boys.
+
+"So you are going to war, too?" said one of the nurses, as she made room
+for them.
+
+"Yes," said Alfred, rather shyly; "we are going back."
+
+"Going back?" remarked one of the doctors. "Did you say 'going back?'"
+he inquired.
+
+"Well, we were with the Belgian army from Liege to Antwerp, and came
+across the northern part of Belgium with them," said Alfred.
+
+"Then you must have seen some fighting?" asked one of the others, much
+interested.
+
+"Yes, indeed; we were in the first battles of the war," said Ralph.
+
+The information was certainly an interesting bit of news. From that time
+on the boys were the center of interest, and many questions were plied
+and answered.
+
+"But where are you bound now?" asked one of the doctors. "If I
+understand correctly, you are attached to the aviation corps, is that
+so?"
+
+"Yes, we are being put up by them, and we may do some flying in a few
+days," said Alfred.
+
+"We do hope you will be successful," said one of the nurses. "Won't you
+tell us where you are from?"
+
+"We are from New York," said Alfred.
+
+"Then you are not English?" she asked.
+
+"Oh, no," replied Alfred. "But that doesn't make any difference. It's
+just the same as though we were English. We want to help out."
+
+There was a merry roar of laughter at this, and Ralph immediately chimed
+in with a sort of explanation: "The Germans didn't treat us right, when
+they captured us, and, anyhow, they had no business to attack Belgium."
+
+"Good for you," said a sweet little miss. "We like Americans, and
+especially those like you who have that spirit."
+
+The vans covered the ground to the general hospital in quick time, and
+the boys were really sorry when the van drew up before the building, but
+they quickly recognized the place where they had accompanied the injured
+aviators the previous day.
+
+"Ralph, we ought to go in and see the lieutenant and Jack," said Alfred.
+
+"Who are they?" interposed the doctor.
+
+"Why, they fell with their machine yesterday, and we helped them out,"
+said Alfred.
+
+"What was the lieutenant's name?" asked the doctor.
+
+"Why, we don't know; we forgot to ask for it; but maybe they will let us
+in," said Ralph.
+
+"Come along," said the doctor. "We'll find a way to get in."
+
+They followed him up the steps, and marched to the office, where the
+doctor was greeted by many of those present.
+
+"Who was it that met with an accident yesterday?" he asked.
+
+"Lieutenant Winston," was the reply.
+
+"And was he badly hurt?" almost shrieked the sweet little nurse who had
+accompanied the party in the van.
+
+"No; he is getting along well," said the attending physician. "He owes
+his life to a couple of brave lads, who happened to be near. He has been
+anxious to see the boys, and has asked where they were."
+
+"We are the ones who helped him," said Ralph. "We want to see him; may
+we?"
+
+"Oh, thank you, thank you so much," said the nurse.
+
+"Do you know him?" inquired Alfred.
+
+"He is my brother; may we go to him at once?" she asked.
+
+"I will take you to him," said the physician.
+
+"So you are Miss Winston?" said Alfred. "Isn't it funny how we happened
+to meet you?"
+
+She almost hugged the boys in her joy at the news, and at her good
+fortune in thus meeting the boys who were instrumental in saving her
+brother.
+
+The lieutenant saw his sister approaching arm in arm with the two boys.
+The greeting was a most affectionate one.
+
+"I met the two boys in Dunkirk; they just happened to get into our van.
+We learned after we got here what they had done. Isn't it noble of
+them?" she said.
+
+"I have tried to find them all day," said the lieutenant, and he pressed
+the hands of the boys. "Yes, I was in an awfully tight place when the
+boys found me; but I am all right now."
+
+They remained with the lieutenant and his sister for more than an hour.
+They had entirely forgotten their appointment with Tom. It was nearly
+twelve o'clock.
+
+"I am afraid we shall have to leave you," said Ralph. "We promised Tom
+to be over at the hangar at eleven."
+
+"Tom Brandon; the American dare-devil?" said the lieutenant, smiling.
+
+"Why, yes," replied Alfred, somewhat hesitatingly. "Is he a dare-devil?"
+he continued, with wide-open eyes.
+
+"Well, he doesn't seem to be afraid of anything; I suppose he would go
+anywhere, if he was ordered to make the trip. Is your engagement an
+important one?" asked the lieutenant, with a curious light in his eye.
+
+"Why,--yes,--we--we wanted to take a flight this afternoon," said Ralph.
+
+"Do you think they would let us?" asked Alfred quickly.
+
+"Rather against the rules and somewhat risky," said the lieutenant,
+slowly shaking his head, but his face relaxed, as he saw the crestfallen
+appearance of the boys. "We can get around the rules sometimes," he
+added.
+
+"Tom said he would try to fix it for us," said Ralph.
+
+"Then go at once, and tell him that Winston gave him permission," said
+the lieutenant. "Do you think it is safe, Addie?" he asked, turning to
+his sister.
+
+"It seems to me it is safe to trust boys who have been in battles as
+they have, don't you?" she replied sweetly, as she arose and grasped the
+boys' hands. "Now, don't forget us, will you?"
+
+"No, indeed; we intend to come over to see you in the morning," said
+Ralph.
+
+The boys fairly flew across the broad grounds in order to reach the
+hangar. Their chagrin was great as they peered in to find that Tom and
+his machine were absent.
+
+"Looking for Tom?" asked one of the men.
+
+"Yes; do you know where he is?" asked Alfred.
+
+"He's coming now, I think," was the reply, as the man approached the
+door and glanced upward. "Yes; there he is, winging it in."
+
+Within two minutes the Morane gave a quick dive, then flattened out and
+skimmed the ground, and just before alighting the nose of the machine
+gave a short, quick, upward dart.
+
+"He does that the slickest of the whole lot. That was a quick stop, sure
+enough," remarked an attendant.
+
+The machine had landed not two hundred feet from the hangar. The boys
+were over without delay, and accosted Tom, as he reached the ground.
+
+"We are sorry that we couldn't get here in time, but we met Lieutenant
+Winston's sister coming over, and we were detained at the hospital,"
+said Ralph.
+
+"It's just as well, as I couldn't make it. The commandant wouldn't give
+me the time to take you out," said Tom.
+
+"But the lieutenant told us to tell you that he gave you permission to
+take us," said Alfred.
+
+"Did he say that? Well, that's another thing. I'll tell the commandant,"
+and, without another word, he crossed the field, and disappeared. He was
+back in five minutes, and waved his hat as he appeared.
+
+"All right, boys; we'll have an hour's flight; how will that suit you?"
+he said.
+
+The boys were too much excited to know what to say in reply. Tom walked
+around the machine, observing every part of the control plane and the
+wires, then mounted the chassis, and with a wrench unscrewed the base of
+the machine gun.
+
+"Here, boys; we'll take this off for the afternoon; it'll give you more
+room. There, take hold of it at both ends, and carry it into the
+hangar," he said, as he handed down the weapon.
+
+"Gee! but that weighs something!" said Ralph.
+
+"Close to eighty pounds, I should say," observed Tom.
+
+"Where shall we sit?" asked Alfred.
+
+"You can easily crowd into the hole in front," said Tom. "Now don't get
+frightened and jump out; I can bring you down easier than that. If it
+seems to turn over, don't mind. That's part of the game."
+
+The Morane was equipped with a self-starter, but three attendants were
+on hand to hold the machine. They took their places and Tom turned on
+the switch. Whir-r-r-r-r,--they felt the tremor of the machine. Soon
+Tom's hand was raised and came down with a swift motion. They felt the
+machine slowly gain headway, and then it seemed to spring forward with
+huge leaps. At first they could feel the oscillating motion of the
+wheels, and as the speed increased there was less jar until finally
+there was no further vertical movement, and they no longer felt the
+wheels traveling over the ground.
+
+"We're up!" shouted Ralph in excitement, as he turned to Tom. The latter
+evidently knew what Ralph meant, even though the noise of the motor
+prevented him from hearing, for he merely smiled, and shook his head.
+
+Alfred leaned over the side of the body, and gazed at the wheels, and as
+he did so something seemed to push the seat of the aeroplane upwardly.
+He quickly turned toward Tom and smiled. They were in the air. How
+glorious it seemed to Ralph and Alfred at that moment. The feeling was
+an indescribable one; they were now going up rapidly; ahead was a tall
+pylon, which seemed to be directly in their way.
+
+Ralph seized Alfred's arm, and pointed toward it, their eyes being
+intently fixed on the square flag which flew above the mast, but the
+machine seemed to whiz by it like a streak. After passing it the machine
+seemed to slow down. They were not aware that the closer you are to an
+object the faster seems to be the motion. Looking down at the earth they
+could note an object for some time, and as they went further up and up,
+things on the earth seemed to pass by with less and less speed.
+
+The most confusing thing to them was the constant change of position.
+Instead of making a straight-away flight Tom circled around the aviation
+field twice, going higher on each turn. The great hangar was plainly
+visible each time they came around, but it grew smaller and smaller.
+
+The boys leaned over the body of the machine, and scanned the earth
+below. It was too grand and inspiring for words. It was some time before
+they began to realize that the hangars were disappearing, and that the
+machine was now going forward in one direction. The country below was a
+confused maze of narrow yellow streaks, bordered by green and yellow
+spots, with innumerable rows of dark green and brown bands and patches,
+which they soon recognized as trees, while cottages and larger buildings
+dotted the whole landscape as far as the eye could reach.
+
+Alfred was the first to cast his eyes to the north. What he saw almost
+startled him. A dark vivid green spread to the horizon, blending with a
+pale mist, far, far away.
+
+"Look! look!" he cried.
+
+"That's the sea!" shouted Ralph.
+
+Tom smiled as he reveled in their joy. He pointed ahead, and the boys
+quickly turned. Far off, in the distance, they saw what seemed to be
+immense fields of snow.
+
+"What can that be?" asked Ralph.
+
+Alfred shook his head, and gazed silently, then turned toward Tom. "Can
+you make it out?" he asked Ralph. The latter shook his head.
+
+The machine went on for ten minutes more. Beyond the white fields
+something else arrested their attention; great clouds of smoke were
+observed. They were not clouds, and there was no fire visible on the
+earth. That was the second mystery.
+
+"I know what that is now," said Ralph.
+
+"What is it?" asked Alfred.
+
+"Tents, tents," said Ralph.
+
+"Yes, and that smoke must come from the big guns," said Alfred.
+
+Ralph turned his head toward Tom, and raised his cap. The latter knew
+that the boys recognized the nature of the scene before them.
+
+"That must be a battle," said Alfred, as he pointed to the great clouds
+of smoke.
+
+"Look way over to the left," shouted Ralph. "See that long, narrow road?
+There is something moving there."
+
+"Why, that is cavalry; sure enough. See, they are turning a corner in
+the road. That's plain enough," said Alfred.
+
+"I wonder if he is going to take us over the German lines?" queried
+Ralph.
+
+"And suppose something happens, and we are compelled to go down; we'll
+be in a nice fix," remarked Alfred.
+
+Ralph shook his head, and glanced back toward Tom. The latter, however,
+soon turned the machine. As he did so a dozen or more aeroplanes came
+into view. They noticed that the machine was going toward a field where
+a huge gas bag was moored near the ground. It was an observation
+balloon. Beyond were several dozens of flying machines drawn up in front
+of the hangars. Tom circled the machine around several times; the earth
+came nearer, and soon they observed a long stretch of green that seemed
+to invite them. In another minute they were several hundred feet from
+the earth, and they seemed to go faster and faster.
+
+"Whew! but doesn't it scoot now," said Alfred.
+
+They grasped the body of the car, while it seemed to fairly sizzle
+through the air. Closer and closer the earth crept up toward them. They
+felt that it would be necessary to hold fast when the shock came. The
+next sensation was most peculiar; the body of the car began to rock up
+and down; the din of the motor had ceased, and they were riding on the
+earth.
+
+
+
+
+CHAPTER IV
+
+TRENCH WORK WITH THE BRITISH FORCES
+
+
+Everyone seemed to know Tom, as he was heartily greeted on all sides.
+The appearance of the boys, however, was a puzzle to the group of
+aviators.
+
+"Let me introduce my friends, Ralph and Alfred, genuine American boys,
+who were with the Belgians in their great fight from Liege to Antwerp,"
+said Tom.
+
+"How did that happen?" asked one of the men, as he grasped their hands.
+
+"We were on the spot when war was declared, and we just pitched in and
+helped them out," replied Ralph.
+
+"Were you in any battles?" asked another.
+
+"Oh, in a dozen, or so," answered Alfred.
+
+"Good boys!" shouted several.
+
+"How did you happen to get here?" asked the first interrogator.
+
+"We came over with the Belgians, from Antwerp," said Ralph.
+
+The foregoing information was enough to introduce the boys, and they
+were gratified to find several other Americans in the party.
+
+The reception was cut short by the peculiar antics of a huge Farman
+machine, which was approaching in an erratic manner. It seemed to dart
+back and forth, and swing around in short circles, as though wounded.
+
+"Something is the matter with Le Clere," shouted Tom.
+
+At that moment the machine darted toward the earth, and the boys held
+their breaths at the anticipated calamity. Fifty feet from the earth the
+machine righted itself, and swooped upward, then, with a vicious plunge,
+it went down and struck the earth, the crash being plainly heard,
+although it landed more than five hundred feet from where they stood.
+
+Every one on the ground rushed toward the fallen aviator. Before they
+reached the scene, two men extricated themselves, and stood on the
+debris.
+
+"What was the matter?" asked Ralph.
+
+"Look at the holes in the wings," said Tom. "That tells the story;
+pretty well riddled."
+
+"Are you all right?" shouted one of the men.
+
+"Yes, but that was a dandy fight, and we brought him down," replied Le
+Clere, a daring Frenchman, who handled the machine gun.
+
+The Gnome motor was lying on the ground twenty feet from the wreckage.
+One of the planes was tilted up at an angle, and was uninjured, but it
+carried the marks of twenty holes, through which the sunlight streamed.
+
+"That will give you an idea of the fascinating work we are engaged in,"
+said Tom, pointing to the bullet marks. The body of the machine was
+wrecked, and the fuselage a mass of splinters. It was, indeed, a mystery
+how the two flyers escaped without injury.
+
+"What will they do with the machine?" asked Alfred.
+
+"They'll build up another out of it in two days," said Tom.
+
+"The Germans are marching west and south of Roubaix," said Le Clere.
+"They have already reached Mons, and are going straight toward Paris."
+
+The boys looked at each other in amazement. It seemed as though their
+trip to Paris would be interrupted, after all. Tom seemed to read their
+thoughts.
+
+"How far is it to Mons?" asked Alfred.
+
+"About fifty miles south," said Tom.
+
+"And what is the name of the town which we saw before we came down?"
+asked Ralph.
+
+"Lille," was the response. "But we must be going back," continued Tom.
+"We are going to move south in the morning, and I have a few things to
+pack up."
+
+After bidding good-bye to every one, they climbed into the airplane, and
+those present gave the boys a cheer, as the machine glided forward. Tom
+had promised to give them an hour's flight, and it was now four
+o'clock. They had heard about taking observations, while on the grounds
+at Lille, and they busied themselves in trying to do work of that
+character. How small the houses were! They could see little creeping
+things, that soon evolved themselves into horses and wagons, but they
+seemed unreal.
+
+The flight to Lille covered a distance of forty-five miles, and it took
+them an hour. It didn't seem that they could have been aloft half of
+that time. Now, on returning, the novelty had worn off, and they were so
+much interested that they forgot to look at their watches until the deep
+blue haze, which betokened the approach to the sea, aroused them.
+
+"Why, it's past five o'clock," said Ralph. "Tom was going for an hour's
+flight only," said Alfred.
+
+"He just said that in fun, I suppose," replied Ralph.
+
+After alighting the boys did not know how to fully express their
+appreciation of Tom's kindness for the great treat, and they inquired
+whether they could not be of some service to him, as they were only too
+anxious to help him out in any way that would be useful.
+
+"Why, no; I don't know what I can put you at," replied Tom. "Of course,
+there's always lots to do about the hangar, and the first thing to learn
+is how the machines are built, and how to handle them; and then, an
+important thing is to learn all the tricks in a gasoline engine."
+
+"That's just what we want to learn," said Alfred, enthusiastically.
+
+"But I thought you had to go to Paris to meet your father?" said Tom.
+
+"Yes," replied Alfred ruefully; "but we can come back. I'm sure there
+will be no objections."
+
+"Of course, it's your first duty to go to Paris--that is, if you can get
+there," said Tom, rather slyly.
+
+There was now nothing for them to do but to make an effort to reach
+Paris. Immediately after landing, they started for the tram way, and
+reached Dunkirk after six in the evening.
+
+"I never was as hungry in my life," said Ralph.
+
+"Do you know why?" answered Alfred.
+
+"Come to think of it, we didn't get anything to eat at noon," was
+Ralph's answer.
+
+After alighting from the cars, their first mission was to seek a
+restaurant, and from that point they soon reached the post office, only
+to be again disappointed. At the telegraph office they had the same bad
+luck.
+
+"I wonder where father is?" said Alfred.
+
+"I suppose we shall have to go, whether we want to or not," suggested
+Ralph. "Let us inquire at the transportation office."
+
+At the main office they soon learned that the troops from England were
+occupying every coach, motor wagon and bus that was in sight, and that
+there was no encouragement in that direction. But an idea occurred to
+Alfred.
+
+"We belong to the army, don't we?" he said.
+
+"Suppose we apply as soldiers, and tell them we must get to Paris at
+once."
+
+They reached the main office of the Army transportation service, and
+boldly made their way to the room indicated by an attendant. In a few
+moments they were ushered in, and saw at least a score or more soldiers
+and officers in the room, at one end of which sat a white-haired
+officer, and several other officers, issuing orders.
+
+"Your business?" said an officer, approaching them.
+
+"We have been with the Belgians, and have just come from Antwerp. We are
+Americans, and are trying to reach Paris, and we wanted to know if we
+couldn't go on one of the trains?" explained Alfred.
+
+The officer shook his head. "I am sorry to say that we cannot provide
+for any one unless connected with the army," he said.
+
+"But we are connected with the army," said Ralph. "We were messengers,
+and have had a lively time, too."
+
+"Yes, and we expect to join the flying corps, but father expects me in
+Paris," said Alfred.
+
+The officer smiled, and pondered a moment. Then, motioning to them, he
+passed out of the room, the boys following. They crossed the hall, and
+entered a narrow room.
+
+"Lieutenant," he said, "issue a permit for these boys to ride on any
+available train to Paris."
+
+The boys expressed their thanks to the officer, and, after giving their
+names and home addresses, they received a card, which stated that the
+Army transport service permitted them to ride on any train where there
+was available room, at the discretion of the officer in charge of the
+train.
+
+"I should advise you to see the officer at the station in the morning,
+and get him to assign you to a train number, as the quickest way," said
+the clerk, as he handed them the permit.
+
+"Nothing like determination," said Ralph. "It is bound to pull you
+through."
+
+It was too late for them to return to the aviation field that evening,
+so after considerable search, they finally found a room, and after
+discussing the events of the day fell asleep, and awoke long after the
+sun had risen.
+
+"We've got to do some hustling," said Ralph. "We ought to see Tom this
+morning and tell him of our good luck."
+
+They partook of a hasty breakfast, and were at the station in order to
+get an assignment. But this was not an easy matter. They waited for
+nearly two hours before they were able to reach the proper official.
+
+"I am sorry to say that we cannot take you today, but I will try to make
+a reservation for you tomorrow. Come here after four this afternoon,"
+said the officer.
+
+"Now for the aviation field," said Alfred.
+
+They were detained for more than an hour watching several newly arrived
+regiments embark on a train, which slowly pulled out to the south, and
+it was nearly noon when the grounds were reached. There seemed to be a
+change in the place. The hangars were empty, and no machines visible. A
+score of men were taking down the temporary hangars and from them it was
+learned that the entire corps had started at eight o'clock for the
+southern station.
+
+"That's too bad!" said Ralph regretfully. "I wish we had started back
+earlier."
+
+"Then we might go to the hospital," suggested Alfred.
+
+The head surgeon remembered the boys. "It's too bad," he said.
+"Lieutenant Winston has been removed to the hospital at Dunkirk, and
+will leave for England tomorrow; but his sister is still here,--ah, here
+she comes."
+
+"Oh, I am so glad to see you. Brother asked for you before he left. If
+you are going to England, you must go to see him. He is at Hempstead."
+
+"We expect to go to Paris tomorrow, and we are sorry not to be able to
+see him," Alfred told her.
+
+They at once returned to Dunkirk, and awaited anxiously until four
+o'clock. Before they had an opportunity to speak to the officer in
+charge, he shook his head, to indicate that there was no room. They
+lingered about, but it appeared to be a hopeless task. Four tracks ran
+by the station office, and these were constantly filled with empty cars,
+then loaded up, and drawn out. They watched the proceedings until the
+sun went down, when tired and hungry, they crossed the street, entered
+a coffee house, and ate a hurried supper.
+
+As they were moving out the doorway, Ralph stopped. Turning to Alfred,
+he said: "We are chumps; that's about the size of it."
+
+"Why so?" asked Alfred.
+
+"We have the permits, haven't we? Why are we waiting for that fellow at
+the station to get us an assignment?" replied Ralph.
+
+"That's a fact; let's make our own assignment; come on," answered
+Alfred. "Is this train going south?" he asked, addressing a soldier who
+was about to enter a half-filled compartment.
+
+"Aw! I dare say it is," was the jolly response.
+
+"Get aboard," said Alfred.
+
+Unabashed, they swung themselves up on the running board, and entered
+the compartment. The occupants glanced at them for a moment, and seeing
+the trim uniforms, at once became inquisitive.
+
+"How did you happen to be directed to this train?" asked one of them.
+
+"Oh, we attended to that ourselves," said Alfred.
+
+"Our permit's all right, but we couldn't wait for them to make up their
+minds when we ought to go; so here we are," said Ralph, with a laugh.
+
+"Well, you fellows'll do; but it's a long way to Tipperary," said a
+voice, which trailed off into the tune of the well-known song. His
+companions chimed in, and it was not long before the occupants of the
+adjoining compartments joined in the song. It was a jolly crowd, but no
+one seemed to know where they were going. All had heard of the rapid
+advance of the Germans toward Paris, and that General French was trying
+to impede their advance somewhere to the south.
+
+It was fully nine o'clock that night before the train made a real start.
+Before that time they were pushed around on the various sidings for an
+hour, and it was a relief to see the fields and feel the continual
+motion of the train as it finally speeded away.
+
+There was no time for talk now. Each tried to find a comfortable place
+in order to get some sleep. They dozed and dozed, as most people are
+liable to do in uncomfortable surroundings, and some hours afterwards an
+orderly appeared at the door, shouting:
+
+"All out, men; form in ranks."
+
+"I suppose we shall have to get out, too," said Alfred.
+
+"Why, no; this can't be Paris," replied Ralph.
+
+"I know bally well it isn't," said a voice.
+
+That settled it; tired and sleepy they swung off the running board, and
+looked at the long lines forming at the side of the train.
+
+"Do you know where we are?" asked Ralph, addressing a soldier at his
+side.
+
+"Don't know, my boy; we've had a steady run, though, for about three
+hours," was the reply.
+
+"We are east of St. Quentin; we passed through the city half an hour
+ago; this isn't much of a hill we are on, but the Germans and French
+fought a battle on this very spot in the campaign of 1870-1," said an
+officer.
+
+Alfred saluted the officer, and asked: "How far are we from Paris, sir?"
+
+"I think it must be fully a hundred miles," was the reply.
+
+The men were ordered to line up, and soon the order came to march. As
+the boys had no other place to go, and the train was even then backing
+toward the city, they marched alongside of the column. The tramp was
+across open fields for a half-mile, where a road was sighted, but it was
+lined with troops, and heavy artillery, going eastwardly.
+
+The column continued on, parallel with the road. It was dry, dusty and
+warm. There was a hum of sounds, and occasionally a boom or two, which
+the boys recognized from their previous experiences. The most emphatic
+voices were those of the drivers, who were piloting the horses drawing
+the artillery and caissons. An hour's march brought them to a small
+stream, which was crossed without waiting for boats or hunting for
+bridges, as it was easily waded.
+
+Across the stream they ascended an elevation, at the crest of which was
+a line of soldiers busily at work with spades and pick-axes. Trenches
+were being formed. They were cheered by the workers, but there was no
+halting. On they went over level ground, only to meet another line of
+men similarly engaged. Several hundred feet beyond an order came like a
+shot: "Halt!"
+
+An orderly came riding up at full speed, and looked around. "We are
+waiting for orders, I suppose," remarked a lieutenant.
+
+The orderly put spurs to his horse, and rode to the right, as he espied
+a group of horsemen. "Form your men along this line, and dig in," he
+directed.
+
+The order was given: "File to the right; halt; stack arms."
+
+Several lorries, which had been following them, came up, and at a word
+of command the men began to unload shovels and picks. This began to look
+like business. It was now growing light, but it still lacked a half hour
+before sunrise.
+
+"Why can't we lend a hand?" inquired Ralph.
+
+"Of course we can," answered Alfred.
+
+They were alongside in an instant. Ralph jumped into the vehicle, and
+helped to hand out the implements, while Alfred tried to edge his way
+in. Their earnestness attracted the officer in charge, and he smiled,
+and nodded his head in approval. Thus two van loads were dumped out, and
+carried forward of the rows of stacked arms.
+
+An engineer officer marked out the line of the trench, and the men were
+set to work. They were now doing the job for a _real_ purpose, as during
+their month of training in England these men had been instructed how to
+go about the business of making trenches, and it was wonderful to see
+how quickly the furrows were dug out. They were about four feet deep,
+the earth being thrown up on the side toward the enemy, thus making a
+shelter trench five feet deep.
+
+As soon as the main line was thus completed, traverses were cut, leading
+out at right angle to the rear of the main trench. These were formed in
+zig-zag fashion, the object being to form shelter sections along the
+entire trench, so that those within would not be subjected to what is
+called an enfilading fire.
+
+
+
+
+CHAPTER V
+
+ON THE FIRING LINE
+
+
+"Look at the guns back there," shouted Ralph, as the company marched
+back to get their first breakfast after three hours of hard work.
+
+"Come on, boys!" said the corporal in charge, smiling at the boys.
+"You've worked pretty hard for lads of your age; come and have something
+to eat."
+
+"So we will," said Alfred; "but what are the guns doing back there?" he
+asked, as he pointed out a battery which had limbered up and was
+wheeling into position.
+
+"You will see in a few moments," replied the corporal, and before they
+reached the mess wagon the guns began to roar.
+
+"How far away are the Germans?" asked Ralph.
+
+"About two and a half miles, I should judge," replied the corporal,
+looking at the battery.
+
+"How can you tell by looking at the guns?" asked Ralph.
+
+"By their angle," was the answer.
+
+Before they ceased speaking, the first shot was fired, then another and
+another, all of them trial shots, as one of the soldiers explained. Then
+another battery to the left, heretofore unnoticed, began to fire, while
+one posted higher up on the right, and two more beyond, chimed in. This
+was a new experience to the boys, as the Belgians, with whom they had
+formerly associated, were lacking in field pieces compared with those
+they now saw and heard.
+
+The challenge was promptly accepted by the Germans, and within fifteen
+minutes the whole crest to the east of them, probably two miles distant,
+seemed to be ablaze. It was singular, however, that none of the missiles
+fell near the troops where the boys were located. On a little elevation
+to the right of the kitchen vans the boys noticed a group of officers
+with field glasses, intently scanning the rear of their position.
+
+"The blooming blokes are shooting too far," remarked a soldier.
+
+"Why are they doing that?" asked Alfred, who overheard him.
+
+"Oh, they'll get the range in time," he replied.
+
+"There's the first airship, to give them a pointer," said the corporal,
+as an airplane appeared in sight.
+
+"Two of our machines are coming up," shouted Ralph. "Now there'll be a
+fight."
+
+Ralph was right. The two English machines steered straight for the
+oncoming Fokker, the latter veering to the left in time to prevent too
+close a meeting. Within a minute three more German machines came into
+sight, their appearance being answered by four of their own machines,
+which came up from the rear, and sailed straight across above them to
+the German positions on the crest of the hill. They were much higher
+than the German machines, the reason being that the enemy had a number
+of anti-airship guns to meet any flyers who dared to cross the line at a
+low altitude.
+
+It was, indeed, an interesting sight to observe the numerous airplanes,
+which were employed by the two forces. They seemed to be flying back and
+forth in the utmost confusion, and, frequently, puffs of smoke would
+indicate that they were firing at each other.
+
+The corporal with whom the boys talked seemed to be unusually well
+informed, and quite a number of the soldiers addressed him for
+information.
+
+"How do they recognize an enemy?" asked Ralph.
+
+"Oh, that's an easy matter," he replied. "I suppose the flyers in the
+air do it on the same principle that we are in the habit of recognizing
+automobiles. Why, I have a lad not ten years old who can tell the make
+of almost any auto the moment he sees it. Generally, if the make of the
+plane is similar to those attached to the aviator's side he is able to
+recognize it by the special mark it carries."
+
+"What mark do you mean?" asked Alfred.
+
+"Why, the English and the French mark is in the form of a circle,
+generally three, each circle being of a different color," was the
+answer.
+
+"There is one,--why, it's red, white and blue," said Ralph.
+
+"That's correct,--those are the colors of the Allies."
+
+"What are the German colors?" asked Ralph.
+
+[Illustration: _Allies' Distinguishing Mark_]
+
+"Black and white," said the corporal.
+
+"Oh, yes, they have a cross," said Alfred.
+
+"Yes; a cross in imitation of the iron cross, so far as its shape is
+concerned," he answered; "that is, a black cross on a white field."
+
+The company marched back to the line. During the next half hour there
+was nothing but expectancy, waiting, waiting,--that most trying thing
+for soldiers, who know that a battle is impending. Then a hundred feet
+to their rear there was a terrific explosion, which startled every one.
+This was followed by others, but none reached the trench line.
+
+Thus, during the whole day, there was an exchange of artillery, the
+greatest damage being done to those in the rear who were trying to get
+to the front.
+
+"With the long range guns the great danger isn't always with the fellows
+in front," said the corporal.
+
+[Illustration: _Black Cross on German Flyers_]
+
+At four that afternoon the company was startled by an order to leave the
+trenches and fall to the rear. Every one cast questioning glances, but
+the knapsacks and rolls were quickly seized, and within ten minutes they
+were in line with the regiments to the right and the left. There was no
+hurrying or disorder.
+
+"I wonder why we are going back?" asked Ralph.
+
+"I suppose it's our business to retreat," returned the corporal.
+
+They marched fully a mile to the rear, passing on the way at least half
+a dozen lines of trenches, which had been thrown up since the boys
+covered the ground the night before. Every trench line was filled with
+soldiers, those in the front being the first to retire. On the way they
+saw how the great shells had played havoc with many of the works.
+
+They again crossed the river, and at six o'clock that night a new line
+was formed, and the spades and picks were again brought into use. The
+booming of cannon was incessant, and, although they tried to get some
+sleep after midnight, they were frequently aroused by the marching of
+troops. At daylight they were again marched out of the trenches, and a
+quarter of a mile from the last trench halted to partake of breakfast.
+
+The march was directly south, and at noon they reached a town of some
+importance, called Chauny. They went through without halting, crossed
+the river Oise, and at four o'clock halted on the eastern banks of a
+stream, which flowed northwardly. Here they waited for orders. A
+picturesque bridge spanned the stream, and the boys wandered across.
+West of the river was a broad expanse of country, perfectly level, and
+thousands of people from the nearby villages lined the road, all
+crossing to the west.
+
+All were excited, and seemed to be going toward the narrow road, which
+led to the left, and, naturally, the boys followed the movement of the
+crowd. Their curiosity was soon satisfied, for beyond was a sight which
+caused their hearts to beat with joy. Fully a dozen airplanes were drawn
+up in line, and the boys started forward on a run that seemed to instill
+the same activity in many others present.
+
+"There's a Morane," said Ralph.
+
+"Yes; and that's Tom getting out of the machine," shouted Alfred, as
+they rushed up and greeted Tom, who looked at them in astonishment.
+
+"And how did you get here?" he inquired.
+
+"Came over with the troops," explained Alfred.
+
+"With what troops?" he was asked.
+
+"Don't know," answered Ralph, "but they are from Essex."
+
+"Well, we've been on duty for a day directly over the lines east of St.
+Quentin," said Tom.
+
+"Did you have a fight?" asked Alfred.
+
+"I should say we did," answered Tom. "Brought down two, at any rate, and
+it was pretty hot for about an hour. So you are on your way to Paris;
+sorry you didn't get back before we started," he added.
+
+"We got to the grounds several hours after you left," said Alfred.
+
+"Glad you came; we can put you up, if you are willing," remarked Tom.
+
+"Thank you for the invitation; we helped them on the trenches and have
+done considerable marching, so it's better than going back to camp,"
+said Ralph.
+
+The boys were up early in the morning, but didn't have the least idea
+what steps to take to continue their journey. Everything in the way of
+transportation was reserved for the troops. Thousands of people were
+leaving their homes, and people with household effects, mounted on all
+sorts of conveyances, were noted on all sides, although at this time the
+Germans were not within ten miles of the river. The nearest railway to
+the south, which ran east and west along the southern bank of the river
+Aisne, was fully ten miles distant from this point.
+
+Tom was on hand early, and greeted the boys most affectionately.
+
+"I have been thinking I might be able to help you out a bit," he said,
+after a little talk. "We are ordered to the station near
+Villers-Cotterets, and that's only forty miles from Paris."
+
+"How can you help us?" inquired Ralph excitedly.
+
+"Probably I can give you a lift in the machine," he said.
+
+"How far is that from here?" asked Alfred.
+
+"Twenty miles," replied Tom, and the two boys looked at each other
+hopefully, as he left them.
+
+Tom re-appeared at three o'clock, and informed them that they would
+start in fifteen minutes.
+
+"If you are ready for the trip, jump in and make yourselves
+comfortable," he said, and they required no second invitation.
+
+The dainty Morane just suited them, and they were in their seats in an
+instant. Tom then tossed them a light package, which they tucked away,
+and the engine began to buzz. As they glanced around, two more machines
+seemed to vie with them in taking the air, then, as they again looked
+around, four more machines began to move, and soon all were on the wing,
+flying side by side, excepting two large Farman machines, which were
+well in the lead.
+
+Up, up, up, they went, the machines on line with each other maintaining
+a height of about four thousand feet, while the Farmans were about five
+hundred feet higher. Within a half hour they saw in the distance what
+appeared to be a silver ribbon running east and west, which proved to be
+the river Aisne, and to the east they saw the city of Soissons. The
+beautiful aviation ground was reached within an hour, and they alighted
+in front of a magnificent group of hangars in the center of well-tilled
+fields, so located as to afford a view in all directions from the
+grounds. The machine was then put up for the night, and Tom and the boys
+were glad to turn in for a much-needed rest.
+
+It was now the first day of September, and there had been nearly one
+month of war. The immense German forces had hewn their way through
+Belgium and entered France, reaching the cities of Laon, Epernay, and
+Chalons-sur-Marnek, thus forming a huge circle. They were within
+forty-five miles of Paris.
+
+When the boys awoke the next morning the first words that greeted them
+were: "The Germans are within five miles of Soissons."
+
+They rushed over to the hangar, but the machine and Tom were not to be
+found. This was another source of grief to them, and they stared about,
+and wondered at this new turn of affairs until, meeting an attendant,
+Ralph inquired:
+
+"Do you know where the Morane has gone?"
+
+"They all started on a reconnoitering trip at five this morning," was
+the reply.
+
+"Do you think they will come back here?" asked Alfred.
+
+"That is doubtful," answered the man.
+
+"Then we shall have to make our way to Paris as best we can," said
+Ralph. "Do you think we would have any chances on the railroad?"
+
+"It's doubtful. I should take my chances over the highway directly
+south, if I wanted to make Paris," answered the man. Then, after a
+little reflection, he added: "A large English force is expected to be
+here from Laon, and it may arrive before noon. Possibly the flyers will
+return, but if the German forces are too close, they will go on to the
+next station at Crepy, directly south of this place."
+
+"Then that's the place for us," proposed Alfred, as he thanked their
+informant.
+
+They had no trouble in getting breakfast and after waiting for an hour,
+during which all sorts of rumors were floating about, they concluded
+that their only course would be to commence the trip. It was not
+necessary for them to inquire the way, as the highway, in the distance
+was filled with fugitives, all trying to get to Paris, or, at least, to
+avoid the invaders while there was yet time.
+
+Reaching the highway, they moved along with the procession, and, shortly
+before twelve o'clock, reached Crepy, ten miles from Soissons. They were
+now twenty-five miles from the center of Paris, and after getting a good
+meal they again took up the march over a beautiful road, which ran
+southeast.
+
+
+
+
+CHAPTER VI
+
+VIGOROUS RED CROSS WORK
+
+
+A mile from the town they came within sight of a cross road, filled with
+an immense concourse, which seemed to be wending its way east.
+Approaching nearer, they recognized troops, artillery and horsemen, the
+latter moving along in the fields parallel with the roadway.
+
+"It seems to me the firing is much nearer than when we started out this
+morning," said Ralph.
+
+As they passed through the marchers, and proceeded along the highway,
+they saw that troops were noticed posted everywhere, and that batteries
+were lying in wait in every advantageous spot.
+
+"I think we made a mistake in taking this road. We should have traveled
+the one which went to the west," said Ralph.
+
+"Then let's go out the first road that crosses this," replied Alfred.
+
+Meanwhile the sounds of battle came nearer and nearer. The artillery
+posted on the elevation began to speak, and before there was time to
+realize it the boys were within the battle zone, and bearing down on the
+road along which they were traveling. They had no trouble, however, in
+leaving the road, as all the fences were down, and many of the fields
+were cut up with the hoofs of horses, and creased by the huge artillery
+wheels.
+
+To add to the confusion, shells began to fall all about them, and
+occasionally a terrific explosion would follow, leaving them dazed and
+startled. They ascended a hill, and, looking back, saw nothing but dense
+clouds of smoke, and a scene of indescribable confusion.
+
+"What's that down there?" shouted Alfred, pointing to a group of vans
+close by the side of a stream.
+
+"That must be a Red Cross station; so it is," said Ralph.
+
+Their footsteps were hurried, but before the place was reached they saw
+stretcher bearers, and also noticed the wounded being unloaded from a
+field van. Glancing to the left they saw fully a dozen vans of like
+character, as indicated by the great red crosses on their sides, rushing
+up the narrow street from the southeast.
+
+"Let's give them a hand," said Alfred.
+
+A business-looking surgeon stood at the rear end of one of the vans, as
+the boys approached. They saluted. "Can we do anything to help out?"
+asked Ralph.
+
+The doctor looked at them for a moment, apparently non-plussed at their
+appearance.
+
+"Yes, indeed; we need you and many more willing ones like you."
+
+"What shall we do?" asked Alfred.
+
+The surgeon drew a pad from his pocket, wrote a few words on it, handed
+it to the boys, and said: "Present this to the officer yonder."
+
+The officer indicated received the slip, while directing the disposition
+of a wounded soldier, glanced at it hurriedly, then looked at the boys.
+"Ah, want to get on duty? We can accommodate you; there, put those
+stretchers in the van. One of you can take this to the supply van," he
+said. Ralph seized the paper, and looked about.
+
+"The van with the flag on it," explained the officer.
+
+Ralph rushed across the intervening space, and presented the paper to a
+Red Cross nurse, who smiled sweetly as she glanced at the paper, and
+looked inquiringly at Ralph. She then turned, seized three packages, and
+handed them to Ralph, while he thanked her and quickly rushed away. The
+packages were stored in the van, water was supplied to the containers in
+the vehicle, and the moment the last article was on board, the van
+started.
+
+The boys were both within, as well as three men and a surgeon. They had
+heard no orders, but knew they were bound for the battlefield. There was
+no talking indulged in. The men were too intently engaged in listening
+to the din of the conflict, and watching the soldiers moving to and fro.
+
+"Has there been much of a fight?" asked Ralph.
+
+"They have been at it all morning," said one of the men. Then, glancing
+at the boys, he continued: "But this is a bad place for you
+youngsters."
+
+"I am afraid you will regret it before you return. The scenes are
+awful," continued the man.
+
+"We know what it is," said Alfred. "We saw the worst kind of fighting in
+Belgium."
+
+[Illustration: _French and German Flags_]
+
+"We were with the English in the battle east of Soissons, and had some
+experience there," said Ralph.
+
+"Aren't you English?" asked the surgeon.
+
+"Oh, no; we're Americans," replied Alfred.
+
+At this point a lieutenant rode up alongside, and shouted: "There has
+been a tough scrap at the mill; we have driven the Germans back; take
+this road down to the river; you will find plenty of poor fellows there
+who will need you."
+
+The French had made a terrific charge at this point, and many were lying
+dead, where the van slowed down, so as to give the surgeon and helpers
+an opportunity to pick out the wounded cases.
+
+Wherever there was a movement in a prone figure the men stopped and made
+an examination. In some cases the wounds were hurriedly dressed, and the
+victim's position rendered comfortable. In other cases the surgeon
+motioned to the helpers, who quickly brought the stretchers, and carried
+the wounded into the van.
+
+On this single trip they attended, or gave first aid to thirty, but only
+the most severely injured were taken into the van, which now turned and
+quickly speeded along the narrow road to the field hospital. Reaching
+this station the men were carefully taken out, their wounds re-examined,
+and carried into a temporary shelter for a second operation or
+treatment.
+
+A huge van then arrived from the southwest. Carefully and tenderly eight
+men were placed on the cots within, the boys being delegated to assist.
+When the order was given to leave, the boys remained in the van, as it
+started out on its journey, but they didn't have the least idea where it
+was bound, although you may be sure they were curious to know.
+
+After every one had settled down,--that is, if such a thing as quiet and
+comfort were possible in a van load of wounded men, Ralph turned to the
+surgeon, and said. "Where are we going?"
+
+"To Paris, if we can get through," was the reply.
+
+The van had a wonderful set of springs, so that, although it was
+necessary hour after hour to go through fields, instead of traveling
+along the road, there was little discomfort to the wounded men.
+
+"Why are the men being taken to Paris?" asked Alfred.
+
+"So as to relieve the emergency station behind the battle front,"
+explained the surgeon. "That is one thing; the other is, that the great
+German forces are driving in our comparatively small army, until the
+Paris forts are reached. There they will be stopped, and we must take
+our wounded with us, and out of the reach of the enemy."
+
+At Dammartin they saw the first Red Cross railway van,--an entire train
+load, filled with wounded from the emergency stations, and here also
+they were joined by fifteen vans taking the wounded on to the city. It
+was thus a fortunate stroke for the boys that they undertook to help the
+field hospital workers, for it directly assisted them in their effort to
+reach the end of their journey.
+
+Traveling was slow, and many detours were necessary, so it was not until
+the fourth day of September that they caught sight of the walls of
+Paris, and they soon had the pleasure of driving over the beautiful
+smooth streets again. They went directly to the center of the city,
+passed down the rue de l'Opera, through the Place de la Concorde, and
+over the bridge to a hospital near the Place des Invalides.
+
+Their charges in the van were soon provided for, and carried into
+comfortable berths. As they were leaving the ward, they heard a weak
+voice calling: "Ralph; Alfred."
+
+They were startled, and turned around with wondering glances. A nurse
+motioned to them, and pointed toward a figure with bandaged head and
+arms. They approached.
+
+"You don't know me, I suppose?" said the voice.
+
+"No,--no," said Ralph.
+
+"I believe it's Tom," said Alfred.
+
+"Right," said the voice.
+
+The boys knelt down at his side at once. "How did it happen?" asked
+Alfred.
+
+"Well, they got me first; but I brought down two of them before I was
+hit," Tom told them.
+
+"What became of the machine?" was Alfred's next question.
+
+"I don't remember anything about it," was the reply, "but they told me
+it made fine kindling wood."
+
+"Too bad!" consoled Alfred. "I liked that little Morane; and to think
+it's all broken up."
+
+"How did you get here?" asked Tom.
+
+"Why, we came down with the Red Cross people," explained Ralph.
+
+"You seem to get into all sorts of trouble, all along the line," said
+Tom with an attempt to laugh.
+
+"But are you badly hurt?" inquired Alfred anxiously.
+
+"The doctors say that there are only a few bones broken, several joints
+wrenched out of shape, and some of the bark peeled off, but I ought to
+be out in a few weeks," said Tom.
+
+"Tell us what we ought to do now?" Alfred asked him.
+
+"What do you mean?"
+
+"Why, I want to know whether they will expect us to keep on in the Red
+Cross service?"
+
+"You volunteered, didn't you?" replied Tom. "You helped them out of your
+free will, and you can leave whenever you want to, if that's what you
+are getting at."
+
+"I wouldn't mind volunteering in the aviation corps," said Ralph. "I
+would just like----"
+
+"So they got you this time, eh?" said a voice.
+
+The boys turned, and saw a handsome man with the uniform of a lieutenant
+in the aviation service, who approached, and leaned over Tom. Tom
+replied with a smile, and raising his injured hand, pointed to the boys.
+
+"Lieutenant," he said, "I want you to get acquainted with two of my
+American friends, who have been in the thick of it right from the start.
+Now you'll be conferring a special favor if you can take them in to help
+you out. Oh, they're bricks," continued Tom, as he saw a shade of
+discouragement in the lieutenant's features, "they are made of the right
+stuff."
+
+"We leave for Verdun in the morning," said the lieutenant, "but I will
+see what can be done in the meantime."
+
+As they left the hospital the first thought was to go to the Continental
+Hotel to try to get a trace of Alfred's father. Arriving there a letter
+was handed them, together with two telegrams from Berne, Switzerland,
+one of the messages having been received that very day. The missives
+informed him that his father had not been able to leave German territory
+until the twenty-eighth of August, and as he had received word that the
+Germans were approaching Paris he thought it unwise to make the trip to
+that point, but would await word from them before deciding what to do.
+
+"How far is it from Berne to Verdun?" Alfred asked the clerk.
+
+"About three hundred kilometers," was the reply.
+
+"Let's see; that's about two hundred miles," said Alfred. "And it's a
+hundred and fifty miles to Verdun.
+
+"Then we'll go to Verdun," said Ralph. "But how?"
+
+The subject was debated for an hour, when it was decided to return to
+the hospital. They had forgotten to learn the lieutenant's name,
+although probably Tom knew how to reach him, they reasoned.
+
+Arriving at the hospital they learned that Tom was asleep, and that no
+one would be permitted to see him, so they wandered around without the
+slightest idea what course to pursue. They even discussed the
+feasibility of walking to Verdun, but that idea was soon abandoned.
+
+"I wonder where the aviation grounds are?" remarked Ralph.
+
+They soon learned that several corps were located at the great race
+course in the Bois de Boulogne, and they were soon on the underground
+railway speeding to the nearest station in that vicinity. Arriving at
+the grounds they approached the entrance, and their hearts sank as they
+saw a great crowd gathered, and one after the other turned away.
+
+"Chances of getting in seem to be pretty slim," said Alfred.
+
+"Well, we might try it, anyhow," said Ralph, as he pushed forward.
+
+They marched up to the gate, and passed through without the least
+objection on the part of the guards. This was the greatest surprise to
+both. They had forgotten that the uniforms they wore gave them
+admittance without question. Evidently they were taken for army
+messengers.
+
+"See that American flag?" shouted Ralph.
+
+"That's the place for us," replied Alfred.
+
+Accordingly, they lost no time in making for the hangar on which the
+emblem appeared. They saw a Farman machine partly outside of the hangar,
+and in the body of it was seated a ruddy-faced chap.
+
+"What's up?" he asked.
+
+"Came over to help you out," said Alfred.
+
+He looked down, and slowly said: "You did, eh?"
+
+"Well, we've seen a little active service at the front, so far,"
+explained Ralph, "been in battle several times, have been captured by
+the Germans, helped to build trenches, worked with the Red Cross people,
+and had a few flights in an airplane, and as we like aviation business
+best of all, we thought we'd come over and go to work."
+
+The airman raised himself, sat down on the side of the car body, and
+commenced to laugh, although Ralph's remark was said without the least
+tinge of pride or boasting. Several from the adjoining hangars came in
+to learn the cause of the boisterous mirth.
+
+"Well, that's fresh enough to come from real American boys," he said,
+after he had sobered down a little.
+
+"That's right; we're from the United States; we came here because we saw
+the flag on the outside; what shall we do the first thing?" said Alfred.
+
+"From America?" said the man, climbing down from the machine. "And you
+are regular Yankees? Well, well; that's too good! I'm something of an
+American myself. By jingo, you're the kind of fellows to have around.
+Want a job? Where did you get your uniforms? They look all right."
+
+"Oh, these are Belgian uniforms. We were with them, you know, and had a
+pretty hot time, too," said Ralph.
+
+This information, as they now knew, was the best credential possible,
+and they were soon the center of an admiring crowd. Somehow the
+determined matter of fact and positive way which the boys adopted had
+the effect of winning their way, and it was thus that they had the
+satisfaction of entering a service which it is a most difficult thing
+to do even with the best credentials.
+
+The happiness of the boys was complete when their new friend told them
+to get up on the machine, and help him to take out the engine. Coats
+came off in a hurry, and they looked around for some substitute to
+protect their clothing.
+
+Their friend supplied the necessary articles at once remarking as he did
+so that he ought to know their names.
+
+After this information was supplied, he remarked: "My name is Martin;
+Bill Martin, Fifth Aviation Corps; don't forget the Corps or you may
+have trouble in getting into the grounds; and, by the way, how did you
+happen to get through?"
+
+"If you mean the gates, why, we just walked right through," said Alfred.
+
+"Just as though you had a right to do so!" said Martin, as he again
+commenced to laugh. "You said you were up in an airplane; where was
+that?"
+
+"Up at Dunkirk, and back of the firing line, south of the St. Quentin,"
+said Ralph.
+
+"Do you know Tom Watkins?" asked Alfred.
+
+"Do I know Tom? Why, we came over together; poor fellow, he got a bad
+fall," said Martin.
+
+"We heard about it and saw him at the hospital today," said Alfred.
+
+"You don't say? So you've been flying with Tom? I'm glad to know that,"
+said Martin, as he nodded his head approvingly.
+
+
+
+
+CHAPTER VII
+
+BOUND FOR VERDUN
+
+
+For three days more the boys wandered about Paris,--three days of the
+most fearful suspense; and then began the battle of the Marne. Every
+airplane in and about Paris was at the front, on the line somewhere, and
+the boys were deprived of the opportunity to see the new friend they had
+made at the Bois de Boulogne station.
+
+They were so sure of being able to go to Verdun that Albert wrote to his
+father of their plans, in the hope that he would consider it wise to
+leave Switzerland for that point, where they might meet.
+
+The Germans had been defeated; Paris was safe, the French line having
+held firmly all the way to Verdun. The determination to go there was
+firmly fixed in their minds, but they could see no way to accomplish the
+purpose. A visit to Tom at the hospital only resulted in their being
+told that the lieutenant was in the field, no one knew where.
+
+"I have an idea," said Ralph, as they emerged from their room one
+morning.
+
+"What is it?" asked Alfred.
+
+"We might get attached to the Red Cross some way, and that would be
+sure to take us to the front," replied Ralph.
+
+"That would be just as hard as to get in with the flying people,"
+answered Alfred.
+
+"That may be so, too, but I can't see any other way."
+
+They again called at the Continental Hotel in the hope that there might
+be some further news. To their surprise they found a letter from
+Alfred's father with a check for their personal expenses. While reading
+the letter they overheard a conversation which gave them the solution,
+as they thought, of their difficulties.
+
+"No," said a voice, "they will not ticket us to any point near the
+firing line, but we might go to St. Dizier, and from there work our way
+north."
+
+"Good idea; let's book at once," said the second voice.
+
+"Come on," said Alfred. "That's the right tip. Let's find out where St.
+Dizier is."
+
+The clerk informed them: "It is about a hundred and sixty miles east of
+Paris."
+
+"Then it can't be far from Verdun," remarked Alfred.
+
+"Sixty miles southwest, I should judge," was the answer.
+
+"Do you think we would have any trouble in reaching that point?" asked
+Ralph.
+
+"I think the trains are still running, but they may not adhere to the
+regular schedule. The line runs south of the war zone, you know," said
+the clerk.
+
+That settled it. They hurried to the Banque Francaise, and having
+secured currency for the check, started for the booking office as fast
+as they could walk. It was impossible at this time to get a conveyance
+as only the underground railways and a few tram cars were in service,
+the government having requisitioned all the horses, and automobiles a
+week previous to this time.
+
+They booked second class, the official stating that the tickets were
+sold at the risk of the holders, and that they would have to take their
+chances on the trains, so they were at the eastern railway station
+before one o'clock, in the hope that the regular through train at two
+that day would be able to accommodate them. In this they were
+disappointed, so they waited about until five o'clock, and had the good
+fortune to have the tickets accepted by the gateman.
+
+They passed through an immense crowd of newly arrived soldiers, and were
+jostled about by hosts of men, women and children who were departing for
+the southeast, most of them bound for Chaumont. Within an hour they
+finally found a train bound for their destination, but it was another
+hour before the train began to move.
+
+The trip was a weary one all through the night, as they seemed to stop
+at every station, although it was the fast express. The intense
+excitement of the people all along the line; the passing of trains; the
+crying out of the latest news; and the bustle of the new arrivals in the
+already crowded compartments, made sleep impossible. The sun had been
+up two hours before the station of St. Dizier was announced.
+
+The boys were out and scampering along the platform ahead of most of the
+crowd. As they passed out the end of the station they noticed a sign on
+a train: "For Bar-le-Duc, 10 o'clock."
+
+"Let's see where that place is," said Alfred.
+
+The information was obtained. It was twenty kilometers northeast.
+
+"That's the place we must go; it's twenty miles toward Verdun, and now
+is our time," said Ralph.
+
+"Let's have something to eat first," said Alfred.
+
+After the meal they booked for Bar-le-Duc, and this train started
+promptly. Only two coaches were reserved for civilians, the others being
+filled with soldiers. The town, which was reached shortly before noon,
+had the appearance of an armed camp. Here they received the startling
+news that the Germans were at St. Mihiel, thirty-five miles northeast of
+that place.
+
+There was no sign of panic there, however. Verdun, Toul and Nancy were
+still intact, and there was no fear that either place would yield.
+
+Before they had been in the city an hour they saw a dozen or more
+airplanes overhead, and it was not long thereafter until they learned
+that one of the most famous stations belonging to the flyers was located
+north of the place. A conveyance was readily obtained, as a line of
+busses paralleled the railway track, and in another hour they were on
+the plateau where the great hangars were located.
+
+As they were crossing the field, and approaching the first tier of
+hangars the boys noticed the two men whose conversation had been
+overheard in the Continental hotel. "They are the very men," said
+Alfred; "I wonder what they are here for?"
+
+The men stopped and looked at the boys for an instant. Ralph approached
+them and said, with a smile: "You beat us here after all."
+
+The men appeared to be puzzled at being thus addressed. Alfred saw that
+they did not understand Ralph's greeting, and said: "We are under
+obligations to you for telling us how to get here, and I want to thank
+you."
+
+"I don't exactly understand," said one of the men.
+
+"We heard you talking about making this trip, and as we wanted to get to
+the front without knowing just how to do it, your conversation helped us
+out," said Ralph.
+
+"I'll bet you're American boys," said one of them, laughing.
+
+"Indeed, we are," said Alfred.
+
+"Belong to the service?" asked the other.
+
+"Oh, yes," answered Ralph,--"that is, we did belong to it."
+
+"Which branch?" asked the man.
+
+"Messenger service in Belgium, aviation and trench service with the
+English, and Red Cross in the French army," answered Alfred.
+
+This response was answered by hearty laughter on the part of both men,
+and one of them responded: "That is a pretty comprehensive service, I
+should say."
+
+"Where are you from?" asked the other.
+
+"New York," answered Ralph. "Why, you look like Americans, too."
+
+"We're from the same place," was the answer.
+
+"And you look like newspaper men," remarked Alfred.
+
+"That's a good guess," was the reply. "But how did you know?" he asked.
+
+"I saw you taking notes as we walked across the field," answered Alfred.
+
+"Good inference," he replied. "Are you looking for a job?"
+
+"Yes, we're going into the aviation service," answered Ralph, with all
+the assurance of a winner.
+
+"See you again," was the final reply, as the two men left them.
+
+"Now, I wonder if they have any American flags at this place?" remarked
+Ralph.
+
+They marched back and forth without a sign of that much desired emblem.
+At one of the hangars two men were tugging at a machine, and slowly
+bringing it out of the hangar. Without a word the boys sprang forward
+and assisted in the operation, an act which brought thanks from the men.
+Then, more in curiosity than anything else, they slowly walked around
+the machine and examined its construction.
+
+The aviator watched them for a few moments. Evidently, to his mind, the
+boys knew all about flying machines, or, at least, must have had some
+acquaintance with them. This seemed to interest him, and he began a
+conversation with them. He soon learned their history, and bestowed
+words of praise on them for what they had done.
+
+"So you want to be aviators, eh?" he inquired.
+
+"Yes, and we'll do anything to get in," said Alfred.
+
+"To be aviators in the service of the Government it will be necessary to
+take the Regulation course," said the man.
+
+"There isn't time for that," said Ralph. "We can help out now, even if
+we don't do any flying, can't we?"
+
+The man chuckled. "I suppose you can tighten up bolts, examine, and
+stretch the stay wires, and things like that?" he remarked.
+
+"As well as take out the engine and overhaul it," added Ralph.
+
+"Well, yes; that's a pretty good job; do you think you could do that?"
+he asked.
+
+"Why, yes; we know something about it," replied Ralph.
+
+"Well, stay around here; we want some handy fellows; but I'm afraid
+you'll have a hard job to get on the pay roll," he added.
+
+"Never mind about that end of it; we want to be doing something; that's
+the main thing," said Alfred.
+
+It would not be interesting to go through the long details of work that
+the boys entered into under those circumstances. Each day for more than
+two months the boys found plenty of work to do. They became general
+favorites at the camp, and while their services were not recognized in
+an official way, as the regulations did not permit of the employment of
+minors, still, in view of the fact that they had such an interesting
+history, and had entered into the work with such zest the commandant at
+the station permitted them to remain, and eventually provided them with
+rations and quarters, to which was added a small pay, such as attached
+to those in the messenger service.
+
+During this period the boys had many opportunities to go aloft on
+practice drills, and on more than one occasion they had the privilege of
+operating the machines while in flight, accompanied, of course, by the
+regular pilots. Attached to the station were a half-dozen machines used
+for the purpose of teaching control, and to enable pupils to become
+familiar with the handling of the machines. They were designed merely to
+skim the ground, the power being so limited that they could not be
+raised from the ground except for very short glides. These the boys
+frequently used, and the experienced aviators were greatly pleased at
+their wonderful progress. It was a strict rule, however, that none but
+regularly licensed aviators should pilot the government machines, and
+that prohibited them from handling the machines on regular service.
+
+It was during the second week of the third month that the boys had the
+first opportunity of showing their capabilities. During a trial flight
+with sub-lieutenant Guyon, while at an altitude of five thousand feet,
+Ralph noticed the machine dart downwardly, and, glancing back, saw
+Guyon's head fall forward, and his hand drop from the lever.
+
+Without waiting to inform Alfred he crawled out of the pit, and seizing
+the control lever, pushed it back in time to bring the ship to an even
+keel. Alfred saw the motion, and followed Ralph. Together they succeeded
+in drawing the pilot to one side, thus enabling Ralph to let himself
+down into the position which enabled him to handle the lateral controls,
+that were operated by the feet.
+
+With Ralph thus fully in control of the machine, Alfred turned his
+attention to poor Guyon, who tried to raise his head, and occasionally
+gasped, as though trying to recover his breath. It was not until the
+machine was nearing the earth that he opened his eyes, and seemed to
+realize his position, but he was too weak to give any instructions or
+render assistance.
+
+Ralph made a good landing, and the moment the machine ceased to move
+Alfred jumped from it, and ran to the office of the surgeon.
+
+"Something is the matter with the lieutenant!" he cried, as he entered
+the door.
+
+"What is the trouble? Where is he?" asked the surgeon, as he moved out
+of the door in response to Alfred's appeal.
+
+"He was taken sick while we were in the air," said Alfred.
+
+"And how did you happen to get down safely?" asked the surgeon.
+
+"We took charge of the machine," replied Alfred.
+
+"Who are _we_?" he asked.
+
+"Ralph and myself; we were up with him."
+
+The lieutenant was being taken from the machine when the surgeon
+arrived. Restoratives were at once applied, and within a half hour the
+attack seemed to wear itself away, and he began to show a normal color.
+
+His eyes rested on Alfred when he awoke from the first quiet nap, and
+raising his hand approvingly said: "That was a good job, Alfred;
+couldn't have been better."
+
+"What do you mean?" asked Alfred.
+
+"You brought us down all right, I mean," he replied.
+
+"Oh, Ralph did that," was the reply of Alfred.
+
+"Well, no matter; you fellows didn't get rattled; that's the main
+thing," said the lieutenant.
+
+An incident of this kind could not remain a secret long in a camp of
+this character. The Commandant took particular occasion to commend them
+for their performance, and it was a long step in their favor when the
+corps moved to the north to take its place in the great aviation camp
+directly south of Verdun.
+
+
+
+
+CHAPTER VIII
+
+AN AEROPLANE AMIDST THE LIGHTNINGS
+
+
+Two days after the occurrence related in the preceding chapter, the
+first section of the Corps was ordered to proceed to the Verdun station.
+Lieutenant Guyon belonged to this part of the force, and, as he had now
+recovered, was instrumental in securing the assignment of the boys to
+his care.
+
+"Then we can go along?" asked Ralph, with some doubts and misgivings, as
+they were packing the belongings of the lieutenant.
+
+"I have arranged that," said the lieutenant.
+
+"What is that?" asked Alfred, who appeared at the door of the hangar.
+
+"We are going," shouted Ralph.
+
+"Yes; you might as well get your things packed and put them in the
+machine," said the lieutenant.
+
+The boys laughed, for outside of a few trinkets, and underclothing, they
+had nothing of importance to take along. They remarked that it was
+singular how few things seemed to be really needed, traveling, as they
+did, from place to place at a moment's notice.
+
+"When do you intend to start?" asked Ralph.
+
+"Whenever we are ready," was the reply. "We intend to leave in squadron
+formation and manoeuver for an hour, and afterwards each is to make for
+the station on his own hook."
+
+Shortly thereafter the first signal was given. The machine was pushed
+out and lined up. At the second signal the machines were mounted. At the
+third tap the motors began to hum, and soon there was a movement in the
+whole line. It was a splendid spectacle, as the machines left the
+ground, and rose majestically toward the west, the direction from which
+the wind was blowing.
+
+The manoeuvers were particularly interesting to the boys, and the
+lieutenant led his section in the formation during the entire practice
+until the captain's flag on the great Duperdessun indicated that the
+machines were free. After making a great sweep to the west the
+lieutenant turned to the left, encircling the town, and pointed due
+east.
+
+Before they had proceeded fifteen kilometers, something happened to the
+engine, for it ceased to hum. They were then at an altitude of a mile,
+and inability to start the motor made it necessary for them to volplane
+to the earth. Sighting a considerable town to the left, which was
+located south of a canal, the machine was directed toward a smooth, open
+field, not far from the environs, and after landing they learned that
+the place was Ligny-en-Barrois.
+
+It was found that through some accident the petrol tank had started a
+leak, and that the liquid was slowly oozing out during the flight,
+without giving the first indication until the engines failed. It was
+just the kind of an accident which necessitated the removal of the
+reservoir in order to make the proper repair.
+
+"Which is the fastest machine?" asked Alfred, while they were waiting
+for the return of the reservoir.
+
+"The Morane, by all means," replied the lieutenant.
+
+"I thought the Caudrons were the best?" remarked Ralph.
+
+"It depends on what you mean by _best_," answered the lieutenant. "The
+different machines are used for various purposes, and while speed is
+important, there are other things just as necessary."
+
+"What other things?" asked Alfred.
+
+"Well, bomb-dropping for one thing; then, some machines are better
+adapted than others for directing artillery fire, or for using machine
+guns," said the lieutenant.
+
+"The captain has a Caudron," said Alfred, "and he doesn't use a gun on
+it either."
+
+"No; the Caudron is admirably adapted for observations, and is used
+almost wholly in France for directing artillery fire," answered the
+lieutenant.
+
+"It seems to me that this machine is good for observing," said Ralph.
+
+"Yes; and it is used for that purpose, but it is now being put to use
+for photographing purposes,--that is, most of the Maurice Farman types
+are so used," answered the lieutenant.
+
+"Why is that?" asked Alfred.
+
+"For two reasons; first, because you will see we can get a good view
+downward; and, second, because it is the most stable machine in flight,
+the latter making it especially well adapted to take good views,"
+replied the lieutenant.
+
+"Which are the largest ships?" asked Ralph.
+
+"The Voisin and the Breguet, by all means. They are able to carry heavy
+loads, and are used as bomb-dropping machines, as their fuselages are
+especially well adapted to carry and release the missiles," said the
+lieutenant.
+
+"But I saw a Voisin at one of the hangars which had a big gun on it,"
+said Ralph.
+
+"Ah, that was the Voisin Cannon, which carries a 37-millimetre gun,"
+said the lieutenant. "That is used for bombarding captive balloons and
+Zeppelins, if the latter should ever make their appearance."
+
+"A 37-millimetre gun?" repeated Alfred.
+
+"Yes; that's about one and a half inch in your measure," answered the
+lieutenant.
+
+Within an hour the reservoir was again in position, and there was no
+delay in again mounting into the air. "We might take a little trip due
+east, as far as Toul, and north of that point we may have the privilege
+of seeing some of the enemy," remarked the lieutenant, as they mounted
+the machine.
+
+A beautiful silver thread now appeared on the landscape to the east, as
+they reached their greatest altitude. Looking back there was a smaller
+thread to the west, and, apparently, the same distance from their
+viewpoint. They thus had the opportunity of seeing, at one glance, two
+of the most noted rivers which figure in the great war,--the Meuse to
+the east, and the Marne in the west, these streams at this point being
+within thirty miles of each other.
+
+It was, probably, imprudent for them to take an out-of-the-way course to
+reach their destination, but the temptation was very great. The sun was
+still shining brightly when they started from Ligny-en-Barrois, but it
+was now growing dark from the overspreading clouds, and as soon as Toul
+was sighted the lieutenant turned the machine northward.
+
+To the west it could now be seen that the threatening clouds were coming
+up, and they appeared to be sweeping toward the east with great speed,
+at right angles to the aviators' course.
+
+"I wonder what the lieutenant will do?" queried Ralph half to himself,
+as he looked at the clouds, and then glanced back to the officer.
+
+The lieutenant shook his head, and pointed the machine further to the
+left.
+
+"Why, I believe he is going right into it!" remarked Alfred in amazement
+to Ralph.
+
+But the officer now made a wide swinging turn. A view of the heavens
+indicated that the storm was an extensive one, and that the speed of the
+wind had increased most alarmingly, for, in looking down they seemed to
+stand still over the little hamlet beneath them. The wind, into which
+they were flying, was traveling at the same speed as the machine.
+
+There was but one course to follow. They must return to the earth,
+otherwise they would be driven far over into the German lines. By
+setting the control lever so as to depress the nose of the machine they
+rapidly descended, the lever being intermittently drawn back to a normal
+position, so as to keep the ship on an even keel and prevent it from
+performing a loop in the air.
+
+The landing was easily made, notwithstanding the wind, and they found
+they were near Commercy, west of the Meuse, about thirty-five miles
+south of Verdun. A terrific rainstorm then followed, which lasted more
+than an hour.
+
+"Were you ever in a rainstorm while flying?"
+
+"Never but once," replied the lieutenant, "and that was in thunder and
+lightning, too, which was the most terrific thing I ever went through."
+
+"Tell us about it!" said Alfred.
+
+"I almost shudder at it when I stop to think of the hour when I faced
+the lightning right where it is made," said the lieutenant. "It was in
+the second week of the war, just east of Rheims, when the Germans were
+sweeping across the frontier and had passed Charleville. I had a
+double-seated Nieuporte, with an assistant handling the machine, while I
+was making observations.
+
+"Shortly after getting the first glimpse of the moving German columns I
+noticed that it was growing dark, but when you are aloft that is not
+noticed as quickly as when on terra firma. The great hosts of Germans
+interested me intensely, and we kept on until I estimated that we were
+fully ten miles behind the advance columns, when my assistant shouted
+through the tube: 'Look back; what are your orders?'
+
+"I saw that to continue would be disastrous, so I gave the order to
+turn. This gave us the first opportunity to determine our speed, or, to
+state it more accurately, the speed of the wind, for you will recall
+that when we turned this afternoon, we seemed to stand still above the
+town.
+
+"Within ten minutes of the time I turned the machine to the west the
+first heavy rolling clouds seemed to meet us. The earth was quickly
+blotted from sight, and heavy rumblings were heard, but no indications
+of lightning. I knew that heavy black clouds were dangerous, and they
+were so black that it was impossible to see my assistant, three feet
+distant.
+
+"I could not decide what to do, so I finally shouted through the tube:
+'keep on a straight course to the west,' for I knew that to land at that
+point would bring us right into the great German column. There was no
+rain falling at the time, but the cloud was like the densest mist. The
+machine was still moving,--that is, the engine was merrily humming, and
+my assistant's voice startled me as he shouted: 'There is something
+wrong; compass out of order.'
+
+"During the flashes I could see him pointing to the compass, and I
+leaned over, and caught a glimpse of the dial. The pointer was swinging
+around violently. The lightning now seemed to be incessant, and the
+rumbling of the thunders was weird beyond description. Sometimes,
+immediately after a vivid flash, a thick spray would deluge our faces."
+
+"What were you thinking about while all this was happening?" asked
+Alfred.
+
+"What impressed me most was the wonderful difference between the
+appearance of those electrical discharges when viewed in the usual way
+from the surface of the earth. I did not notice any forked lightning,
+nor did it show itself in streaks, darting hither and thither. It seemed
+to be more like balls of fire, suddenly appearing here and there, and
+when each ball burst into flame, there would be a crackling sound, at
+any rate, so it seemed, for I dared not stop the engine.
+
+"But the most remarkable thing was the odor which was present. It had a
+pungent smell, not at all unpleasant, but decidedly exhilarating in its
+effects. I suppose we were taking in ample doses of laughing gas, for I
+assure you that after the first experience, we had no particular sense
+of danger. It was most fascinating, and I felt as though I was being
+raised up on my seat. Occasionally I would try to figure out how this
+would end, but on the whole it was devoid of terror."
+
+"How long were you in the storm?" asked Ralph.
+
+"Well, I was so fascinated that I had forgotten to look at the watch. I
+held it before me, and soon noticed that it was nearly five o'clock, so
+that we were over an hour and a half in the thick of it. During this
+experience what gave me the queerest feeling was the compass, the needle
+of which could not be seen, it swung around with such velocity. Were we
+going with the storm, or not? That was the thing uppermost in my mind.
+If we were being carried along we might be even in Belgium by the time I
+noted the watch.
+
+"Then I tried an experiment. I ordered my assistant to make a turning
+movement. This convinced me that we were really going with the storm,
+and were now far over into German territory. Strange as it may seem, we
+were not thrown hither and thither; the ship sailed along smoothly. I
+feared to make the next experiment,--that is, to direct the machine
+toward the earth, for, while everything worked perfectly, I had a
+feeling that it would be safer to reach the earth with an engine running
+than with a dead one. Slowly the machine went down; it seemed to get
+lighter, but now the thunder came in sharp claps, and the form of the
+lightning changed. I could distinctly see what the observer sees when on
+the earth, long, zig-zag streaks multiplied a hundred times more than
+anything I ever witnessed while on earth."
+
+"How high were you up when you got out of the clouds?" asked Ralph.
+
+"Seven hundred and seventy meters (about 2,900 feet), as indicated on
+the barometer."
+
+"Could you see the earth?" asked Alfred.
+
+"No, indeed; the rain was pouring down; it was splashing over us and all
+about us, and I signalled to go up again, and we soon entered the
+clouds; but during all this time the needle of the compass kept
+spinning, so that we knew nothing of the direction we were traveling."
+
+"But couldn't you tell which way the wind was blowing?" asked Ralph.
+
+"No; we were moving with the great air current, sometimes sailing with
+it, and at other times against it, but with nothing below to indicate
+the direction. We could not possibly say whether we were going north or
+south."
+
+"I think if I should be in the air and couldn't see the earth I would
+know a way to tell which way the storm was moving," said Ralph.
+
+"How?" asked the lieutenant, as he leaned forward.
+
+"Why, the rain would come down at an angle, if the wind should be
+blowing, wouldn't it?" replied Alfred.
+
+"Quite true, that would be the case on the earth; but it would not be so
+up where the raindrops are being formed; there the little particles of
+water move along with the wind stream; but that is not all; when you are
+in a machine in a great wind movement, the ship must move through the
+wind in one direction or the other at all times so as to keep aloft,
+hence, whether you are going with or against the wind, the rain drops
+appear to be coming down at an angle, and this, in itself would be
+sufficient to deceive you, or, at any rate prevent you from determining
+the direction in which you happened to be sailing."
+
+"How did you get down?" asked Alfred.
+
+"That was the interesting part of it. After a half hour more of flying I
+again ordered the assistant to go down two hundred meters. It was now
+evident that the storm was abating. Soon we again passed out of the rain
+clouds, and the assistant shouted that he had reached the level
+indicated. 'Go lower,' I shouted. As we did so it grew lighter, and we
+began to feel a relief. 'Lower yet,' I ordered. At 600 meters the rain
+poured steadily, but still nothing was visible."
+
+"You were up then about a half a mile," said Ralph.
+
+"Just about that," was the reply. "Soon we noticed a peculiar white
+patch, and then another. This was puzzle to me. 'Go still lower,' I
+shouted, and down went the machine. Then we saw some white houses, and I
+almost shouted for joy. But where could we be? We were passing over a
+city, a city located within the bend of a large river. I racked my brain
+to find out where and what it could be. If it was the river Meuse it
+might be Verdun, or Sedan, or Charleville. We were forced to go down
+still lower, and then I could see forts, and I felt sure we were over
+Sedan.
+
+"We were even then going east. I was so agitated that I could hardly
+speak, and motioned to my assistant to turn around. He understood, and
+the ship was swung around; we were now going right into the blinding
+rain, but we were fifty miles behind the German advance columns, and in
+order to enable us to make more rapid progress I told the assistant to
+change the course nearly due south. We were flying very low, certainly
+not over a thousand feet.
+
+"Thus far we had not seen a soldier, or any evidences of warfare. In a
+half hour we sighted another stream. My heart leaped with joy, for I was
+sure it must be the Aisne. To assure myself of this we followed the
+stream for twenty kilometers, and then the forests of Argonne came into
+sight, thus assuring me of the position. I knew that the army of the
+Crown Prince was in that region, and it would not be safe to descend; I,
+therefore, directed the machine to the west, crossed the river, and was
+about to go still lower, when I heard a boom,--several of them.
+
+"This startled me, you may be sure. 'Up, up!' I shouted. The machine
+obeyed. We rose to an altitude of eight hundred meters, then suddenly
+the engine stopped. My assistant turned and shouted: 'We have no
+petrol.' I crawled back and tested the tank. It was empty. 'Volplane to
+the south,' I said. It was the only thing I could do. Now that the
+engine was silent the sounds from the earth were startling. There was
+terrific firing to the right and left, and all about us; but we must go
+down; there was no help for that.
+
+"Soon the earth again came in sight, and then the location of the
+batteries was made out by the volumes of smoke, which could be seen at
+each volley. My assistant tried to hold up the machine as long as
+possible, but we were now down to 300 meters, then the barometer
+registered 250. We both noticed a large, apparently smooth field, and
+the final volplane began. We landed a hundred feet from a first-line
+trench, and although the Germans made it hot for us for about fifteen
+minutes we were soon able to reach the laterals and thus escape their
+fire. But the machine was in a bad condition when we rescued it that
+night. It was literally shot full of holes. What is left of it is now in
+the end warehouse where the scraps are kept."
+
+
+
+
+CHAPTER IX
+
+A CHAPTER OF LESSONS ABOUT THE AEROPLANE
+
+
+Early the following morning there was intense activity in the camp, and
+Ralph was among the first to learn the cause of the excitement. Several
+army divisions had come up in the night, and were bound for the Verdun
+sector, and from the information obtained it was the intention of the
+commander to make a terrific assault in order to break the German lines
+north of the city.
+
+The lieutenant, when approached, admitted that they were now in for
+double duty. "Every man in the corps must report and be ready in the
+morning. There will be two days of observation, and then look out for
+some business."
+
+"When will we go to Verdun?" asked Ralph.
+
+"We are expecting orders at any moment," was the reply.
+
+During the previous afternoon more than fifty machines had assembled,
+and some of those were now leaving, a few going directly east, on
+observation tours, while others were circling about and testing the
+engines.
+
+"I am expecting a big Farman machine," said Lieutenant Guyon, as he
+returned from headquarters an hour afterwards, "that is equipped for
+carrying bombs, but I am told it is one of the speediest machines in the
+service. It will easily carry six hundred kilos in bombs (1,200 pounds),
+and we are ordered to wait here until it arrives."
+
+When the boys were alone, Alfred, with a glint of joy in his eyes,
+remarked: "I think that will give us an opportunity to do some flying
+with the lieutenant."
+
+"Do you think so?" replied Ralph, elated at the thought.
+
+"I am sure of that," said a voice behind them.
+
+They quickly turned and saw the lieutenant, who had entered unobserved.
+They saw by the smile on his face that the remark was an agreeable one,
+for he continued:
+
+"Yes, and the machine is now here; the men are at work setting it up; so
+we might as well go over and help out."
+
+A second invitation was not necessary. Ralph, who was outside in one
+bound, rushed across the field, but Alfred accompanied the lieutenant to
+the commandant's office, where they were provided with the receipt for
+the machine. The lieutenant remained here while Alfred carried the
+document to the warehouse. Within two hours the machine was in condition
+to receive the fuel and the supplies usually carried in the machines for
+emergencies.
+
+When the lieutenant returned he made a careful inspection, and on this
+occasion the boys followed every movement of his to learn what were the
+essential requirements in inspecting. Naturally, the most important
+thing was to know that every part of the frame is not only properly set
+up and the wires made taut, but that the fastenings, the turnbuckles,
+are in good condition. That necessitated a minute examination of every
+one of them.
+
+Then the planes were sighted to ascertain whether they were properly
+aligned. Sometimes when the planes are not exactly parallel with each
+other, the end of one, for instance, being set a little higher or lower
+than the other, it is usually corrected by letting out one or more sets
+of brace wires and taking up on others. This observation was followed by
+a careful look at the control planes. These are the sensitive parts of
+the plane, and may be likened to feelers, for the slightest warping of
+the horizontal tail planes will frequently cause the machine to fly with
+a skidding motion, not dangerous, but exceedingly uncomfortable when
+flying at a high rate of speed.
+
+"The wires leading to the control levers are always a source of worry to
+me," remarked the lieutenant, and he drew himself up into the rear part
+of the chassis. "You will notice that this one rubs along the side of
+that brace. I could not permit that," he said, as he glanced toward one
+of the workers.
+
+"Do you think it would weaken the brace?" asked Ralph.
+
+"No, it's not that," replied the lieutenant. "The difficulty is that
+all these wires are stranded, and as soon as one of the wires wears out
+by the frictional contact, another will give way, and the control wire
+is liable to part at the most critical time."
+
+The boys had occasion to remember the lieutenant's warning shortly
+thereafter. After an examination of the airplane structure an
+investigation was made of the engine. The mechanic turned it over to be
+sure that the compression was all right. Self-starters are provided on
+all these machines, as the French learned at an early day that it would
+be unwise to depend on cranking.
+
+Then a thorough inspection of the pipes and tubing for the fuel and
+lubrication was made. The dashboard of an aeroplane is a much more
+wonderful contrivance than the dashboard of an automobile. The aviator
+must look out for several things not necessary when traveling on land.
+
+The machine which they were examining had on it the most improved
+contrivances, which had been found desirable, some of which were
+entirely new to the boys, one of them being the inclinometer.
+
+"That must be a dandy thing," said Alfred, pointing to it.
+
+"I think there are only a few of the military machines which are
+supplied with them, but the order has been given to put them on all the
+new machines," said the lieutenant.
+
+"What are the two rods for?" asked Ralph, as he looked at the
+inclinometer.
+
+[Illustration: FIG. 6. INSTRUMENT BOARD OF STANDARD AIRPLANE.
+

+
+"The two rods which swing past the vertical bar, on which you see the
+numbers, indicate the angle at which the machine is going. All that is
+necessary is to observe the crossing point of the rod over the marked
+bar, and it will instantly tell what the angle of ascent or descent is.
+You see an aviator now has so many things to think of that he must have
+devices of various kinds which will constantly tell him anything or any
+condition without asking for it."
+
+"Why, this also tells how fast the engine turns," remarked Alfred.
+
+"Of what use is that?" asked Ralph.
+
+"Well; if you knew that the engine was capable, under full throttle, to
+make eighteen hundred revolutions a minute, and the dial showed that the
+shaft was turning only one thousand, you would quickly get the idea that
+something was wrong," answered the lieutenant.
+
+"Oh, yes; and then you would start to make an investigation at once
+without waiting for the engine to stop," said Alfred.
+
+"Exactly; it is there as a warning, just as a headache is a warning that
+something is wrong, or a pain, which is nature's way to indicate that an
+investigation should be made without delay," answered the lieutenant
+with a nod.
+
+Besides the foregoing, the dash had on it a watch. Now, a watch may be a
+convenient thing to have on an automobile, but it is not a necessity. On
+a scouting and observation plane it is one of the necessary implements.
+Alfred laughed, as he looked at the neat little clock face.
+
+"I suppose," he said, "we could get along without that."
+
+"Of course we could," answered the lieutenant. "But why get along
+without it when we now find it such a necessary element?"
+
+"Necessary how?" asked Ralph, in surprise.
+
+"In determining distances, for one thing," answered the lieutenant.
+
+"A watch to tell the distance?" asked Alfred incredulously.
+
+"Yes, indeed," responded the lieutenant. "If you saw a puff of smoke in
+the distance, and shortly thereafter heard a boom, the distance could be
+determined almost instantaneously by roughly calculating 1,200 feet for
+every second. You see, the clock there has a second hand, which is very
+plain, for that very purpose."
+
+"But suppose there is a regular battle on, it would be hard to tell
+about the boom from any particular gun, wouldn't it?" asked Ralph.
+
+"Quite true; in such a case it would be useless for that purpose.
+Another use is in signaling," continued the lieutenant. "For instance,
+in sending information to a battery, arrangement is sometimes made to
+flash the distance by means of second intervals."
+
+"How is that done?" asked Alfred, now growing intensely interested in
+the details of the dashboard mechanism.
+
+"It is an easy matter to signal numbers," answered the lieutenant and a
+favorite plan is to fly over the area where the enemy's battery is
+located, then flash at that altitude. The gunner will take the angle,
+set his piece and fire, the aviator, meanwhile, noting the course and
+effect of the shot. By means of the watch he can determine the distance,
+counting either by the time of flight of the missile, or by the elapsed
+time between the flash of the gun and the landing of the shot.
+
+The altimeter is another very important part of the equipment. It is a
+device which tells at a glance how high the machine is flying, and Ralph
+looked at it with a somewhat doubtful expression. The lieutenant saw the
+questioning lines on his face, and instantly divined the reason.
+
+"You are in doubt whether the altimeter can be relied on? Am I correct?"
+he asked.
+
+"Well, I suppose it is all right, but almost every time we have been up
+and took the readings, we found we were actually hundreds of feet less
+than the altimeter actually showed, so I am wondering if it is possible
+really to tell the exact height by that apparatus," remarked Alfred.
+
+"Yes, I understand what you mean," replied the lieutenant. "The other
+day, when we made the long flight from Bar-le-Duc, the device we had
+showed 900 meters, for it was an automatically registering barometer, as
+all of them practically are. When we returned I noted on the report book
+872 meters. Did you notice that?"
+
+"Yes, and I wondered at it at the time," said Alfred.
+
+"I knew that the general altitude of the country at that place, as
+indicated by the topographical charts, was 28 meters above sea level so
+I merely subtracted 28 from 900, and that showed how far up above the
+land we really were," said the lieutenant.
+
+"Of course, it's a satisfaction to know how high one is flying," said
+Ralph.
+
+"It is not only a satisfaction, but it is an absolute necessity for an
+aviator to know how high he is flying, if his mission is to convey any
+information to the batteries in the rear," said the lieutenant.
+
+"And how is that done?" asked Alfred.
+
+"By a system of triangulation," he replied. "In a few days we may have
+an opportunity to use the system, and I will explain it then so you can
+quickly grasp the subject."
+
+The air speed indicator was another interesting device, but at that the
+lieutenant shook his head as though doubting its general value.
+
+"Don't you think it's accurate?" inquired Alfred of the officer.
+
+"Oh, yes; it is as accurate as it can be made. In fact all devices,
+which are used to indicate the speed of the wind, are nearly perfect.
+That is not the difficulty. When it is used on a flying machine several
+new things enter into the problem, which makes it difficult for the
+instrument to be truthful."
+
+"What is the main trouble?" asked Alfred.
+
+"Well, suppose we are starting a flight against a wind, which is moving
+at the rate of, say, ten miles an hour," answered the lieutenant.
+"While in flight we note that, going against the wind, the air speed is
+sixty miles. Now, if we happened to stop suddenly so we were poised in
+the air, the indicator would show the air speed to be ten miles, so that
+we were really going only fifty miles. If, now, the machine is turned so
+that we are going at right angles to the movement of the wind, although
+we may be going actually through the air at a speed of seventy miles an
+hour, the indicator does not register the air speed at all, because it
+is in such a position that the air does not affect it and the only
+indication we have is the speed of the air relative to the movement of
+the machine,--or, to put it in a better way, I might say that the
+instrument only registers, in reality, the speed at which the aeroplane
+goes through the air, and no more."
+
+"But is that the only way to tell how fast we are going?" asked Ralph.
+
+"The best test is to take the engine revolutions. A certain machine
+after it has been properly tested in a calm, and also in wind currents
+of different velocities, will show a record of speed with the engine
+running at certain revolutions. An experienced aviator can judge pretty
+well, by experience, what the speed of the wind is, and, knowing the
+propeller speed, and the direction he is going relative to the wind, he
+can make a fair estimate of the speed of the machine."
+
+
+
+
+CHAPTER X
+
+A THRILLING EXPERIENCE IN THE AIR
+
+
+It was with feelings of joy that the boys stepped out of their tent the
+following morning to learn that the lieutenant had decided on a trial
+spin in the forenoon, preparatory to the real start, which was to take
+place at two in the afternoon. The engine was turned over, and the
+machine held down while the usual hour's running test was going on.
+Everything seemed to be in order, the engine was stopped and another
+inspection made when the lieutenant gave the order to mount the machine.
+
+In this type of military machine the swivel gun is at the extreme
+forward end, and the pilot directly behind the gunner, and at a slight
+elevation above the gun. Both gunner and pilot are housed in, and in
+most cases strapped to the body of the machine to prevent any accidental
+falling out, as there have been numerous accidents due to men being
+thrown from their perches.
+
+The boys found ample room in the forward pit, and at a word the machine
+was released and glided forward. The new machine gave them a sensation
+different from the former one, as it appeared to ride more easily and
+steadily. In fact, there is just the same difference in the motion of
+flying machines as there is in autos, some, the small machines, seeming
+to glide over the ground and impart every bump to the occupants, as
+might be expected of a light machine.
+
+A heavy flying machine, however, seems to move along with the utmost
+ease, and does not sway from side to side when sailing through cross
+currents. Naturally, such a machine is a more stable base for machine
+guns as well as for observation.
+
+Alfred's particular hobby was kodaking. On this occasion, the first time
+he had an opportunity, he prepared himself with a camera. The
+lieutenant, learning of Alfred's penchant in this direction, had a
+regulation government instrument sent over, and attached to the machine,
+to Alfred's surprise.
+
+Before starting out, the lieutenant said: "I want to give you some
+points now, in using the camera. Photographs, in order to have any
+military value, must be identified,--that is, they must be made at such
+altitudes, and with reference to certain marked characteristics on the
+earth, that we may be able to place them on the topographical maps of
+the particular section, and thus verify them day after day."
+
+"What do you mean by verifying them day after day?" asked Alfred.
+
+"I mean by that to see what changes have taken place in the same view
+between the taking of the two pictures," replied the officer.
+
+"Well, what possible changes could take place in a day or two?" asked
+Ralph in astonishment.
+
+"A great many, and very important ones, too," answered the lieutenant.
+"The camera sees what the eye does not notice. If a picture is taken of
+a certain section today, and the following day another picture is
+snapped, a comparison of the two will show whether or not there has been
+a movement of troops, or, whether or not a certain undistinguishable
+object was something movable, or not."
+
+"Is that the way the map of the enemy's country is made up?" asked
+Alfred.
+
+"Yes, and every detail is noted, so that when you commence the work be
+careful to notice something which will distinguish the exact place where
+you are located; also put down the direction of the flight over that
+same area, and the altitude at which we are flying."
+
+As the machine glided over the treetops and the village on the northern
+border of the Meuse, the sun shone out with intense brilliancy. They
+were going directly east, and both boys turned toward the lieutenant,
+their eyes seeming to say: "So you are going to take a peep at the
+front, by way of experiment?" which was exactly what the lieutenant
+purposed doing.
+
+The altimeter now registered 1800 meters, considerably over a mile high.
+From that point they could see to Verdun, and thirty miles east of
+Verdun, could be noted the blurred outlines and surroundings of Metz,
+that greatest of all fortified German defences. On they went for nearly
+three-quarters of an hour until a stream of some magnitude appeared to
+the east, which they soon crossed.
+
+They afterwards learned that this was the Mosel, which flows through
+Metz. The latter city now loomed up so it could be plainly seen, and to
+their right was another town, Nancy, a fortified French place. They were
+about midway between the two places.
+
+Suddenly an aeroplane appeared to the right, and the lieutenant turned
+the machine in that direction. The boys were relieved to see the great
+circle on the control planes of the machine in the distance, which
+showed them it was a French reconnoitering airplane. In the east several
+other machines were noticed hovering about, and the lieutenant at first
+headed directly for them, but he soon turned to the north.
+
+Below were seen numerous flashes of guns, and they knew from this that
+the fighting lines must be along the river. The most startling thing
+which occurred was a tremendous explosion that seemed to be right in the
+machine itself, and they looked around startled at the suddenness of it,
+for everything seemed peaceful enough to them at that altitude.
+
+The lieutenant turned the machine, however, as he apprehended more
+trouble, now that the gunners below had so luckily secured a fair range.
+The first shot was followed in another moment by another, and the
+lieutenant now began to dart the machine back and forth, and turn it in
+short, sharp circles.
+
+Another explosion took place, this time remarkably close, and pieces of
+the flying machine came down, and brushed past the boys. The lieutenant
+shook his head, as the boys glanced back. The machine was now circling
+around, a peculiar manoeuver, the boys thought, as they looked at each
+other for a possible explanation.
+
+Ralph looked back, and noticed that the lieutenant, with an alarmed look
+on his face, was constantly glancing back to the tail planes. The
+steering lever seemed to be jammed. Ralph had an idea that something was
+wrong, and crawled over the body until he was alongside of the
+lieutenant. The latter pointed to the control lever, and Ralph
+understood.
+
+Without waiting for instructions from the lieutenant, he cautiously made
+his way along the chassis, following up the wires which were indicated
+by the lieutenant. Within four feet of the tail plane Ralph halted.
+Then, reaching down, he succeeded in grasping a dangling wire, and held
+up the end for the lieutenant's inspection. After several attempts he
+found the other end of the wire, which had been severed by a shot from a
+shrapnel shell.
+
+The ship was still circling around, so without waiting to repair the
+break Ralph turned the rudder, and, glancing at the lieutenant, saw the
+latter smile, and then by motions direct him to give the control plane a
+still further push in the right direction. It was impossible for Ralph
+to hear anything the lieutenant said, but as soon as the airplane was
+fairly headed for the west, the power was shut off, and the machine
+began to descend.
+
+"Good boy!" shouted the lieutenant. "Can you fasten them together?" he
+asked.
+
+"I am afraid not," replied Ralph. "A piece seems to have been shot away.
+But I can take care of it if you will only direct me to pull it to the
+right or to the left."
+
+"All right, then. Do you see that great patch of green, directly beyond
+the castle?" asked the lieutenant.
+
+"I can see it plainly," replied Ralph. "Shall I steer for it?" he asked.
+
+"Oh, no. We must come up from the south. Note the direction of the wind
+from the smoke. Make a long sweep. We are now at an altitude of 1200
+meters. We can volplane twelve kilometers from this height," remarked
+the lieutenant.
+
+The turn was made to the south in a long sweep, Ralph continually
+glancing forward to note the direction indicated by the lieutenant.
+
+"Now straight ahead, and hold steady."
+
+They were now rapidly approaching the earth; the machine gliding over
+the tops of the trees at the border of the forest that ran along the
+river bank. To their right, across the river, was a large town,
+Pont-a-Mousson, and the castle ahead of them was a large school, from
+which even then hundreds of children were emerging, and excitedly
+rushing toward the approaching machine.
+
+Down went the machine at a sharper angle; then, when close to the earth,
+the rear control was sharply turned, and the nose of the ship raised up,
+but for an instant only, when the machine settled down, and, after
+running along a hundred feet, stopped.
+
+The agitated children pressed about, and the lieutenant tried in vain to
+keep them off. Some more venturesome than others, after seeing Ralph and
+Alfred, began to question them. To the relief of the boys they learned
+that the French out-posts were less than a mile distant.
+
+"Let us make the repairs as rapidly as possible," said the lieutenant.
+
+An examination showed that not only was the control wire cut in two
+places, but the vertical plane had its pivot shot away, thus accounting
+for the peculiar action of the lever, which seemed to jam whenever an
+attempt was made to turn it to the right. Ralph did not know this, while
+seated astride the body and manipulating the plane, and it was obvious
+that even though he had succeeded in splicing the wire, it would have
+been impossible, with the rudder in that condition, to turn by means of
+the wire controls.
+
+Assisted by the machinist from the garage belonging to the owner of the
+school, they completed the repairs in an hour, and, hungry though they
+were, they again went aloft and sailed for their camp, which was reached
+after an absence of three hours.
+
+They thus had less than a hour to get a hurried meal and prepare to
+line up with the squadron, to carry out the orders for the movement to
+the north. They were now going to that section of the fighting line in
+France where the most intense struggles up to that time had taken place,
+and where, ever since the opening of the conflict the most stupendous
+operations were being carried out to gain the mastery.
+
+Imagine, if you can, the sight that met their gaze, as they took their
+place on the extreme right of the three squadrons, which were about to
+launch on this memorable occasion. They were about twenty miles south of
+the city of Verdun. The extreme northern aviation base was not more than
+eight miles southwest of the city, located on a level plain east of the
+forest of Argonne, and close to the Aire river, a tributary of the
+Aisne.
+
+The trip was a short one, as the actual flying distance was less than
+fifteen miles. Long before they reached the scene of the great camp,
+they could see the thousands of vehicles, and the hundreds of thousands
+of soldiers, on the highways, in the fields, and around the villages
+along the two main railways which threaded their way along the wide
+valleys between the Meuse and the Aire.
+
+During every mile of the trip they were under the constant vigilance of
+the officers, who moved them into echelon, formed them into squares, or
+caused them to trail in columns of two or three, the object being to
+accustom the pilots to obey and execute signals while in flight.
+
+
+
+
+CHAPTER XI
+
+A FIGHT AND A LANDING IN BELGIUM
+
+
+The day following their arrival at the field base, as it was called,
+they found a wonderful change in the order and arrangement of the place.
+Everything was done in the most systematic way. So many machines, from
+each squadron, were told off each morning for certain duties. Those
+duties were as follows: First, scouting. This meant ascertaining where
+the enemy was most active; where the batteries were located; noting the
+movement of troops, and their general character.
+
+Scouts generally operate in pairs, for if it is impossible to signal
+back from the ships, one continues the work while the other makes a
+signaling report from such point or points in the rear as will make the
+information useful.
+
+The next duty is to protect the scouts from interference. This work is
+carried on by the large ships, which are usually provided with rapid
+fire guns. They need not, necessarily, be speedy, for they are to keep
+in touch with the speedy scout ships, the latter of which sail around
+over a small area so the observations can be carried on as leisurely as
+possible.
+
+Third come the bomb-throwers, usually heavy-powered machines, generally
+not armed, as all the carrying power is devoted to the transportation of
+bombs. These are also guarded by the heavily armed machines. Sometimes,
+as in the case of the Farman machine, which the lieutenant used, they
+were used for scouting, and were also serviceable for fighting purposes.
+
+In the early period of the war there were not many pilots capable of
+doing the duty required in all branches of the service. It was
+frequently the case that the aviator would command a ship with a gun on
+it and do double duty, acting as scout, or he would chase and fight an
+enemy, manipulating the gun while manoeuvering the machine. It was the
+sort of duty in which Lieutenant Guyon was engaged at the time he was
+promoted to the command, and supplied with the new type of machine.
+
+Naturally, as commander of the squadron, he was at liberty to take any
+one he desired in his flights, and as he had a real affection for the
+boys, he took delight in having them accompany him on many of his
+exploits. It was the custom for the lieutenant to entrust the piloting
+of the machine to one of the boys, while he acted as a scout. Frequently
+Ralph would perform this duty, while Alfred, with his camera engaged,
+under the direction of the lieutenant, taking such photos as were deemed
+necessary to supplement the Department maps.
+
+Thus over a month was spent in scouting duty, and, as the weather
+became somewhat chilly, especially in the evenings, they never went
+aloft without being well muffled up. One morning the lieutenant called
+out to the boys that they were likely to have a busy day before them, as
+the weather was unusually mild for the season.
+
+When they arrived at the hangar the machine was already out of the shed,
+and the lieutenant was busy with the charts in consultation with the
+officer of the day. Evidently something unusual was afoot, for they
+waited more than an hour before the lieutenant re-appeared.
+
+"You might wrap up well," he said. "I have ordered a good luncheon, as
+we shall have a good long scouting area to cover."
+
+"Which way are we going?" asked Ralph.
+
+"Directly across the city, and then to the east. There is some unusually
+active business going on between this and Metz."
+
+"Think I had better load up the camera pretty well, even though it is a
+little misty," said Alfred.
+
+"By all means," responded the lieutenant.
+
+It was eleven o'clock before all was ready, when the lieutenant,
+addressing Ralph, said: "After we pass over Verdun, going east, we cross
+what is called the La Pietrie forests. The principal towns we shall
+visit are Conflans and Briey, both within the German lines. Through
+those towns are the principal railway lines which supply the enemy
+forces to the west with provisions and ammunition. We have eight bombs
+aboard to be used at convenient points. After lightening up the machine
+by disposing of them we may make a visit to Longwy, a town twenty-two
+miles north of Verdun. We ought to have good maps of the railroad
+sections over there."
+
+As they arose the weather was somewhat hazy, so it was difficult to make
+observations at high altitudes. They, therefore, ascended at available
+points, and took a number of snapshots. To the left the Meuse river, and
+the edge of the forest beyond were distinctly visible, although they
+were then registering an altitude of more than 5,000 feet, and were five
+miles east of the river. To the east was an impenetrable haze, so the
+lieutenant directed the machine toward the river, and soon the German
+encampment and lines were visible through Barencourt.
+
+All were on the alert to notice signs of the enemy's machines, for they
+were now in such a position that the Germans would be most likely to
+observe them, but there was not an indication that they would be
+molested. They then turned the machine to the northeast where a bridge
+was visible in the distance, and the lieutenant shouted through the
+tube:
+
+"Make for the first bridge; follow the track on this side for a quarter
+of a mile, so as to give me a chance to aim. Then take the second bridge
+to the north further on, and in doing so pass the factory beyond."
+
+"I understand," said Ralph.
+
+The track was reached, and directions followed. Long before they were
+over the bridge the lieutenant pushed down the lever which released a
+bomb, which could plainly be seen at first, but they soon lost sight of
+the flying missile. A moment later the second bomb was released. How
+long it seemed for even the first bomb to reach the earth! As they were
+directly over the bridge an explosion was plainly visible. The first
+bomb had missed the bridge, but before they had time to comment on it
+the second one burst at the end of the bridge, and one of the spans went
+down.
+
+[Illustration: _A Dangerous Position_]
+
+The factory was now in view. "Go down lower," shouted the lieutenant.
+
+Alfred nudged the lieutenant, and pointed to the north. "That looks like
+an airship," he said.
+
+"So it is," replied the lieutenant, after a hasty glance. "But we must
+attend to this little business first," he continued, as his foot was
+extended down to the bomb dropper.
+
+"You have hit it!" shouted Alfred in glee. "Now for the other bridge."
+
+They were not as successful with the last structure, although three
+bombs were expended on it.
+
+"Now, where is the flyer you saw?" asked the lieutenant.
+
+"It went easy just before we reached the second bridge," said Alfred. "I
+don't see it now."
+
+"Then I suppose we shall have to go to Longwy to find where it is," said
+the lieutenant. "Can you see the city beyond?" he continued, pointing to
+the north. "Go to the left of the city," he said through the tube.
+
+"Why did you tell him to go to the left?" asked Alfred.
+
+"In that way we can avoid the long range aircraft guns, which we know
+are mounted in the forts to the east of the town," was the reply.
+
+They were soon on the northern side of the town, and in looking south
+they were surprised to see two machines, one making for the east and the
+other seeming to fly directly toward them.
+
+"That fellow will be a little surprised when he finds what he has to
+deal with," said the lieutenant with a chuckle.
+
+"It's a Fokker, isn't it?" shouted Ralph through the tube.
+
+"Quite right; when I give the signal turn to the left, and describe a
+sharp circle. I'll fool him," said the lieutenant.
+
+The signal came; the machine veered around just as the Fokker came
+plainly into sight. As the turn was made the lieutenant turned the
+machine gun to the other side, and when the sight was cleared past the
+wings he gave the first turn of the crank to the gun.
+
+There was a hum and a succession of cracks, which seemed to surprise the
+man in the Fokker. He evidently thought that the French machine was
+trying to get away, or it never would have ventured so close.
+
+"The other machine is coming!" cried Alfred.
+
+"Here is where we can get in the fun," said the lieutenant. "Make a
+straight line for the one coming up in the east. Go on until I signal."
+
+This was a most audacious move, and while Ralph was guiding the machine
+toward the stranger the lieutenant poured a constant stream of shot into
+the first comer. It must not be assumed, however, that the German
+machines were idle during this period. Both were firing, but the shots
+went wild, especially after the daring move just made.
+
+"Up! up! as high as you can go!" was the next order.
+
+The machine tilted, and the lieutenant looked back at Ralph approvingly.
+"She is a dandy climber," said the lieutenant musingly. "Now I'd like to
+see them follow a bit."
+
+One of the machines actually tried to imitate them, but the other ship
+was noticed wavering and swaying from side to side.
+
+"Something is the matter with that fellow," said Alfred.
+
+"Yes; he's done for, and we can easily polish off the other one,"
+remarked the lieutenant, as he watched the falling machine. "Now turn
+around quickly and dive for the one who is trailing us," said the
+lieutenant through the tube.
+
+Ralph banked the machine, and brought it around as quickly as possible.
+The machine was not a quick-turning one, but the oncoming machine was
+not prepared for the manoeuver, for it seemed to hesitate which way to
+go. If it went to the left it would be impossible to use its gun, and if
+it turned to the right it would be at the mercy of the Frenchman's gun.
+The only remedy was to dive; down went the machine at a sharp angle. The
+lieutenant's shots went wild, but they were soon rid of their
+troublesome companion.
+
+"I suppose we'll have the whole German flying corps after us now," said
+the lieutenant. "Turn for home."
+
+No sooner had they turned than another machine came up, this time a most
+determined fellow.
+
+"Up! up!" again came the command, "and keep pointing that way. You might
+also veer to the left."
+
+This time it was one of the well-known Taubes, with the disadvantage,
+however, that she was a tractor,--that is, had the propeller in front,
+like the Bleriot monoplane, so that it prevented the driver from
+shooting head on, whereas the Farman biplane was a pusher,--that is, had
+the gun mounted in front, and the propeller behind the planes. During
+the evolution of circling, however, the biplane had to present a
+broadside, which gave the Taube a chance to pour in a stream of shot,
+many of which took effect.
+
+"That was a close shot!" shouted Ralph through the tube. The lieutenant
+looked back, and pointed to the tube. A shot had gone through it,
+causing Alfred and Ralph to look at each other in undisguised dismay.
+
+[Illustration: _A Safety Manoeuver_]
+
+At every turn the lieutenant ground out the shot, and soon the barometer
+registered a height of 6,400 feet. Two miles more and the Taube made a
+peculiar turn, and glided to the right.
+
+"You have hit him," said Alfred in excitement, and the lieutenant
+stopped churning.
+
+"It seems like it," was the reply. "When we come back on the circle, go
+lower," he said to Ralph, "and I can finish him."
+
+As they crept up closer and closer, the lieutenant, with his hand on the
+crank, waited for the final chance. Like a dying gladiator the Taube
+turned, and a most terrific storm of shot came from the quick firer.
+This was the only time that the boys actually heard the thuds of the
+striking missiles on the body of the machine. It proved to be the last
+effort of the Taube; it dropped away, but still held its upright
+position.
+
+Instantly the engine of the biplane stopped. The lieutenant, with his
+hand still on the crank, turned and shouted:
+
+"What is the matter?"
+
+There was dead silence, and sudden darkness, for they could not see in
+either direction. They had entered a dense cloud.
+
+"Have we started on the down glide?" continued the lieutenant.
+
+"I am trying to hold it up," said Ralph. As he spoke they emerged from
+the cloud, but the Taube was nowhere in sight.
+
+"Try the starter," said the lieutenant feverishly.
+
+"Can't do it," was the reply.
+
+"Then hold it steady while I examine the tank," said the lieutenant. He
+leaned over, and almost immediately exclaimed: "The connection is shot
+away."
+
+"I will make a long glide if you can fix it in the meantime," said
+Ralph.
+
+"No; I will connect the other tank," was the reply.
+
+It required less than a minute to perform this operation, but despite
+the repair the engine would not turn.
+
+After another examination the lieutenant looked up from the pit, and
+said: "It's all up now. The other tank is also empty."
+
+The barometer now showed that they were only a little over three
+thousand feet above the earth. A landing must be made, that was evident;
+but where? Alfred pointed to a forest, directly east.
+
+"That might be a good place to come down, because there doesn't seem to
+be any houses there."
+
+"Just the place if we can find a spot big enough," said the lieutenant.
+
+With his field glasses he scanned the forest.
+
+"Do you see that strip of dark green a little to the left? That is a
+clear space, I am sure. Steer for that after circling around. We are
+still high enough to enable us to make a careful observation of the
+spot."
+
+The machine descended in its regular glide, and they passed over the
+indicated spot.
+
+"That is a dandy place if you can hit it right," said Alfred.
+
+It was narrow, not more than a hundred feet wide, but it extended
+diagonally up the hill, not the most desirable place to land, by any
+means, but it was the only thing to be done.
+
+"Where shall I land?" asked Ralph.
+
+"Try to strike the second clump of brush; do you see what I mean?" asked
+the lieutenant, his words tumbling over each other in his haste.
+
+"I can do it," was the reply.
+
+"May you have good luck," said the lieutenant.
+
+They approached the end of the open space between the trees. Fortunately
+the wind was not blowing, and the fuselage struck the first clump of
+brush, but they passed over it without difficulty. Ralph then threw up
+the elevator sharply, and the front end tilted, while the body of the
+machine sank down gently, and the landing was made without a jar.
+
+"That was the most beautiful thing I ever saw. You deserve great credit
+for that piece of work," said the lieutenant, as he leaned back and
+patted Ralph.
+
+They leaped from the machine, and for a moment stood there helpless with
+the reaction which set in, the boys, particularly, being influenced by
+the great strain. The lieutenant was the first to speak: "Well, here we
+are in a pretty fix; but it might be worse," he said.
+
+"No; we haven't a drop of petrol left," said Ralph ruefully. "Both tanks
+were perforated."
+
+They sat down to consider the situation. It was now past five o'clock,
+and although it was generally the custom to take luncheon with them on
+these trips, the extra amount which had been stored was barely
+sufficient for a half meal. The sun was going down, and they had no idea
+of their location except that, by calculating, the lieutenant judged
+they might be fifteen miles northeast of Longwy. Everything was still,
+except the evening chirrup of the birds.
+
+"It is too late to do any investigating tonight; but our first duty in
+the morning must be to arrange for food," said the lieutenant.
+
+Fortunately, they had taken the precaution to carry plenty of wraps, so
+they were not at all uncomfortable. They gathered leaves, made up
+comfortable berths, and, after a most exciting day, slept soundly all
+night.
+
+As soon as the first grey of the morning sun lightened up they arose,
+and began an investigation of the surrounding vicinity. A reconnoitering
+journey was proposed, as, during the night, faint whistles of
+locomotives could be heard coming from the east.
+
+"That is the direction we must go," said the lieutenant, as they
+prepared themselves for the trip.
+
+They entered a dense forest, setting their course by the compass, and
+marched due east for an hour without seeing the first sign of
+habitation, when they were suddenly startled by a locomotive whistle,
+which could not be more than a mile away. They drew back and listened
+for a time, then cautiously crept forward, looking for an opening. A
+quarter of a mile to the left they discovered a wagon trail leading to
+the north.
+
+This began to look as though some one might be living in the vicinity.
+The trail was followed, as cautiously and as closely as possible, and a
+mile beyond a cabin was sighted. This was the time for them to exercise
+care, but they felt sure the people living there would sympathize with
+them.
+
+"You see, we are in Belgium now, and they hate the Germans," said the
+lieutenant. "I suppose we are close to the border of Luxemburg, and the
+people there feel the same as the Belgians."
+
+"Do you know a place in Belgium called Bovigny?" asked Ralph.
+
+"Yes," responded the lieutenant. "That is on the other side of
+Luxemburg, close to the frontier. Why do you ask?"
+
+"That is where we entered Belgium, and near where we assisted in
+capturing the auto load of Germans," said Alfred.
+
+"Yes, Bovigny is less than forty miles from this place," said the
+lieutenant.
+
+"Isn't that strange," said Ralph. "Here we are, close to the place where
+we started on this excursion. Why, we made a regular circle to get
+here," and they laughed at the situation.
+
+It was now past six o'clock in the morning. No one was in sight, and
+they assumed it might be too early for the people, so they waited for an
+hour; still there was no sign that the cabin was occupied.
+
+"I suppose we might as well go closer and investigate." They went
+forward without seeing a sign of life, except a dozen or more chickens,
+which were scattered over the lawn to the rear of the cabin. "If there
+is any one there a whistle might bring them out," continued the
+lieutenant.
+
+There was no response, and after waiting a short time they circled about
+the house, and they saw that the front door was open, but there was no
+furniture within. They then boldly approached, and began to examine the
+contents of the rooms. Not a scrap of food was found, although ants and
+other vermin were numerous, and there was a mouldy smell in the second
+room, there being only two compartments or rooms. While they were
+searching about, two chickens appeared at the door, and with a common
+instinct the boys encouraged a closer acquaintance, to the amusement of
+the lieutenant. One of the chickens was finally trapped, and a meal was
+soon prepared and cooked in the oven. They had barely time to finish the
+repast, when a shot was heard in the woods to the south, at which they
+hurriedly left the cottage, and rushed to the nearest clump of brush
+across the clearing. A second shot followed, evidently quite near, but
+apparently from the same direction as the first.
+
+"They are probably hunters," remarked the lieutenant.
+
+"Isn't our machine over in that direction?" asked Ralph.
+
+"Undoubtedly," said the lieutenant.
+
+"I wonder what they would do if they found it?" queried Alfred.
+
+"I think it would be perfectly safe if the hunters are natives. I am
+sure they would suspect the truth, for they would at once recognize it
+as a French machine," replied the lieutenant.
+
+"Would it be safe to go in that direction?" asked Alfred.
+
+"That was in my mind," replied the lieutenant. "As we must find some
+one in this region, and they seem to me to be the most likely fellows to
+approach, come on," he added.
+
+They hurriedly went forward, expecting every minute to catch sight of
+the hunters. Their progress was slow, as the ground was full of leaves,
+and the wood thick; besides, there was considerable underbrush. They
+thus wearily tramped on and on for more than an hour, covering a
+distance which should have brought them close to the location of their
+machine. Despite all their efforts it could not be found nor the place
+located.
+
+The only remedy was to retrace their steps and go back to the cabin, and
+from that place they could readily follow the wagon road back to the
+place where they emerged from the woods. The cottage was reached shortly
+after noon, and an hour was spent in catching several of the chickens
+and roasting them, so that it was in the middle of the afternoon before
+they again retraced their steps back to the starting point.
+
+Here another difficulty presented itself. They could not find the place
+where they first reached the trail, so they sat down to wait for the
+welcome sound of a train to guide them. Even that aid was denied them,
+and as darkness was now coming on a suitable place was found to rest for
+the night at the base of an uprooted tree. There the night was spent in
+comparative comfort, as, fortunately, the weather still continued mild
+and agreeable.
+
+The matter of food now became a vital one, but so, also, was the
+necessity of locating the airplane. The matter was debated, and the
+lieutenant finally said: "We must find our machine; from that point I
+think we should strike to the west. It would be unwise for us to
+approach the railroad to the east, as that is in the hands of the
+Germans, and every mile of it is patrolled."
+
+By means of the compass they trudged to the west, and soon reached
+familiar ground. As they were about to enter the open space, which was
+recognized as their landing place, voices were heard. The three glanced
+at each other in dismay, until Alfred's keen ears detected a French word
+or two, of which he quickly advised his companions.
+
+"I will call to them in French," said the lieutenant.
+
+He did so, and the two men, for the lieutenant could now distinctly see
+them, were startled, but in another moment returned an answer.
+
+"We are French," said the lieutenant. "That is our machine, and we have
+been reconnoitering."
+
+"We are friends," said one of the men.
+
+In another moment the lieutenant and the boys were at the machine, and
+grasped the hands of the hunters. "We are Belgians," continued the man.
+
+"Where are we?" asked the lieutenant.
+
+"In the forest, north of Messanoy," was the reply.
+
+"Are there any Germans near?" asked the lieutenant.
+
+"Yes, at St. Leger, to the north, and at the junction of Arlon, to the
+northeast. But troops are constantly going along both roads to Longwy
+and Metz," replied one of the spokesmen.
+
+"Where can we get something to eat?" was asked.
+
+"Ah, we can arrange that," said one of the men with a smile. "Follow
+us."
+
+On the way the lieutenant learned a great deal of the system in force by
+the Germans. They were conducted north, through the woods for fully a
+mile where they reached a wagon trail. Here the lieutenant stopped.
+
+"Where does this trail lead?" he asked.
+
+"From the railway station on the east line to a little village on the
+west side of the forest," was the answer.
+
+"Then we were on this trail yesterday," said Ralph.
+
+If they had gone a quarter of a mile farther, after reaching the
+cottage, they could have seen the first cottage in the village. It was
+also learned that the two men were the hunters whose shots were heard
+the previous day while at the cabin. The men lived a quarter of a mile
+from the village, in the elevated part, near the border of the forest,
+and like true Belgians were glad to help their French brothers.
+
+
+
+
+CHAPTER XII
+
+EXCITING EXPLOITS ON LAND
+
+
+"That is the place where I live," said the elder of the two men, as he
+pointed to a low cottage on the side of a hill, "and Raoul here lives
+below the turn. We must approach the house cautiously, for we know spies
+to be in this part of the country."
+
+"I will go ahead," said Raoul. "Follow and go up to your house through
+the orchard."
+
+They tarried by the roadside until the signal appeared. Upon reaching
+the house they were greeted by Felix's wife, for that was the name Raoul
+bestowed on his friend. A good meal was soon spread before them, and in
+the meantime the lieutenant was plied with questions, as the people in
+that section had no opportunities for learning what was really taking
+place in the outside world.
+
+Finally the lieutenant asked: "Do you know of any place where we could
+get some petrol?"
+
+The men mused for a while, and shook their heads. "You know," Felix
+said, "everything around here is controlled by the Germans, and petrol
+is one of the things that is kept strictly under guard."
+
+"Do you know the place where they store it?" inquired the lieutenant.
+
+"Yes, but it would be dangerous to attempt to get any of it," said
+Raoul.
+
+"I have a plan," said Felix, "but we cannot do anything before night. I
+know every step of the way to the station, and will take you there this
+evening."
+
+"Good!" said the lieutenant. "In the meantime, give me a diagram of the
+station, and the roads leading to it. That will help me to become
+familiar with the surroundings."
+
+For the next hour the lieutenant was busily engaged in learning all
+about the country, and where the stores and ammunition were kept.
+
+"I think we might as well have some of that petrol," said the lieutenant
+with a smile, as he looked at the boys, who nodded their approval, as
+they were keen to participate in the plans which the lieutenant had
+formed.
+
+That night, after ten o'clock, they appeared at their place of
+concealment, for it was thought wise to keep away from the house in the
+event any of the prying neighbors should happen in. Together they
+cautiously found their way to the railway and walked along the track
+until the first switch was reached. While waiting there so that Felix
+could point out the different objects, Ralph drew the lever, and set it
+so the first train would take the switch.
+
+The lieutenant saw it and nodded approvingly. Ahead a few hundred feet
+was a low building, which was reached by the track which led from the
+switch.
+
+"The guards are stationed at that shed across the track, and sometimes
+they come over," said Felix.
+
+"But is the building open?" asked the lieutenant.
+
+"There are no doors; only open arches. The tanks can be loaded and
+unloaded from the tracks," was the answer.
+
+They were carrying three vessels, such as are usually employed for
+transporting petrol in small quantities, and nearing the shed the
+lieutenant said: "Remain here and await my orders. I will go ahead and
+investigate."
+
+With two of the receptacles in his hands he crouched as low as possible,
+and made his way along the track, but before reaching the structure he
+left the track, and approached the shed from the south side. He was gone
+for more than fifteen minutes, and when he returned with the receptacles
+filled he immediately seized the other, returning with it also filled in
+a few minutes.
+
+"Now, take these to the cross road, and out of sight. I will be there in
+fifteen minutes," and saying this he quietly left them.
+
+The boys and Felix carried the cans to the designated place with the
+greatest care, for the fluid was precious to them. No sooner had they
+hidden the receptacles when something like a flash of lightning
+illuminated everything about them, and this was followed by an
+explosion.
+
+Felix gasped as he gazed in the direction of the sheds, for he divined
+the cause. The boys, too, were startled.
+
+"I wonder if the lieutenant did that?" asked Ralph.
+
+"I have no doubt of it," replied Felix.
+
+"Do you really think he did it? I wonder if he is hurt?" said Alfred,
+his voice in a tremor.
+
+They waited for more than a half hour. What if the lieutenant had been
+caught in the catastrophe? They could see the soldiers at the station
+rushing hither and thither, and the people were going toward the station
+from all directions.
+
+"Mighty good thing we hid in this place," said Felix.
+
+Felix and the boys were now in consternation, and as they had about
+decided to go up to their former place of concealment, the headlight of
+a train approached from the south. It slowed down a little as it neared
+the station.
+
+"The switch!" was Ralph's exclamation. As he said that the train reached
+the switch, and turned to the track leading to the fiercely burning
+shed. Half of the train ran through a sea of fire before it could be
+checked. It was a terrifying sight, and Ralph shook with fear at the
+sight. Fortunately, it was a freight train, or the toll of death would
+have been awful.
+
+"This begins to look bad for us. I am afraid the lieutenant has been
+captured. This place is getting to be too dangerous, and we must leave
+at once," said Felix, as he seized one of the cans.
+
+"I will go down and see what the trouble is," said Alfred, but Felix
+shook his head. Nevertheless, although Ralph also remonstrated, and
+insisted on accompanying him, Alfred had his way. One would be safer
+than two, he thought, and without further words he crawled along the
+fence, avoiding contact with those who were in the near vicinity.
+
+A few minutes after Alfred left, the lieutenant returned, and was
+shocked to learn of Alfred's journey.
+
+"Take these cans up to the house, and I will go back and try to find
+him," he told them.
+
+Alfred, meanwhile, had reached the track near the switch, and not far
+from the rear end of the burning train. As he was about to cross the
+track his foot struck an object, and he fell across the track. He was
+surprised to see several men appear and gaze at him, and it must be
+admitted that he was decidedly nervous over the situation. However, he
+did not venture to say anything, but quickly started at the fire, for he
+now stood with others, in the full glare of the flames. As no one paid
+any attention to him, it occurred to him that he had as much right there
+as the villagers.
+
+All about him he heard criticisms of the calamity, and some one
+suggested that the fire and explosion was caused by a French airship,
+and, in fact, this seemed to be the general opinion.
+
+Alfred wandered about listlessly, now feeling assured that the people
+knew nothing of the lieutenant, for he was certain that the news of the
+capture of a Frenchman would cause great excitement. Waiting the first
+opportunity, he slipped over the fence, and crawled along in the shadow
+of some brush for several hundred feet, when, to his consternation, a
+tall man arose in his path.
+
+He turned, and was about to leap the fence, when he heard a familiar
+voice: "Alfred."
+
+He immediately recognized the lieutenant, and it is questionable which
+of the two felt happier at the meeting. They quickly ascended the hill,
+where they met a gloomy pair in Ralph and Felix, and the lieutenant told
+his story. He had allowed the petrol to run from one of the tanks after
+he took away the last receptacle, and when he returned he tapped three
+of the other tanks, expecting to wait five or ten minutes before firing
+it.
+
+While thus waiting two of the guards approached, and he hid behind a box
+car on the opposite siding. He feared that his plans had miscarried, for
+he felt sure the guards would discover the petrol. They did not,
+however, go into the sheds, but remained outside, engaged in
+conversation for more than ten minutes. When they left he lost no time
+in again crossing the track.
+
+He reasoned that the whole of the interior of the first set of sheds
+must have been flooded by that time, and the problem now was to ignite
+it, and get away safely, so he struck a match and lighted a small
+saturated cloth, which was thrown into the nearest opening. It caught
+instantly, and as the entire shed was now filled with the vapor, the
+explosion followed before he could get across the track. It was so
+great in violence that he was hoisted from his feet, so it seemed to
+him, and completely stunned. How long he remained in that condition of
+half stupor he did not know, but he soon heard a babel of voices, and
+saw everything about him as bright as day. Then, to his surprise, a
+train came up the switch, and rushed through the fire. It was this which
+probably saved him from being detected.
+
+"You may be sure," he said, "that as soon as my senses returned I knew
+what had happened, and that train started my sluggish brain into
+activity. I ran away from the train, and so did several others. No one
+cared to follow me, thinking, of course, that I belonged to the crew.
+That explains my long absence."
+
+"Now, how are we to get the petrol over to the machine?" asked Ralph.
+
+"We must ask Felix about it," said the lieutenant. "Probably you can
+help us out in that direction?"
+
+"I have a light wagon," said Felix, "but we must not venture out with it
+until after midnight; in the meantime I will go down to the village and
+get all the news."
+
+He returned in an hour. "It is reported that an airship did the damage,"
+said Felix.
+
+Shortly after two o'clock in the morning the light wagon was on hand,
+and Raoul accompanied them. After loading the wagon with the cans they
+started on the trip through the forest. Felix and Raoul both remained
+with the lieutenant and the boys until the tanks were repaired, and the
+sun had appeared. The machine was then turned around, and headed for the
+opening in the forest through which they had entered. Felix and Raoul,
+in the meantime, diligently cut away the underbrush and bushes in the
+path of the machine so it would be able to make a fair start.
+
+The boys now mounted the machine after shaking hands with the two men,
+and the lieutenant, reaching into his pocket, drew out a hundred franc
+note, which he tendered to them. They refused to take it. The lieutenant
+then threw it on the ground, saying: "This belongs to Belgium, and you
+had better take it."
+
+"Good bye, and God bless you," shouted Felix, as the motor began to hum.
+The machine gliding down the incline quickly gathered speed, and it was
+soon in the air.
+
+After reaching an altitude of a thousand meters, the lieutenant said:
+"It would be interesting to pay the village a visit after our pleasant
+experience there."
+
+Ralph, accordingly, turned the rudder, and the machine swung to the
+right. It required only a few minutes to reach the scene, and there,
+notwithstanding the distance, they could see the blackened and still
+smoking ruins in the two immense spaces adjoining the station.
+
+Now, for the first time, they appreciated the fact that a worthy task
+had been accomplished, for this station was one of the most important
+oil supply points along that whole line.
+
+The soldiers were rushing wildly about the station grounds, and the
+officials there were no doubt now assured, after seeing the machine,
+that the depot had actually been destroyed by a bomb from that airplane.
+
+The machine was now directed toward Longwy, and after giving that city a
+wide berth, flew directly south, with Verdun as the objective. The
+grounds below and to the west of that city were reached before ten
+o'clock, to the astonishment of the men quartered there, for it had been
+reported the night before that the lieutenant and the boys had been
+captured or killed in the fight at Longwy.
+
+The lieutenant won the cross for the exploit, and the boys received
+honorable mention from the government.
+
+
+
+
+CHAPTER XIII
+
+A DARING BOMB RAID TO THE RHINE
+
+
+The exploits of the lieutenant and the boys soon became the talk of the
+camp. From enemy sources more was learned later about the results of the
+destruction of the oil station, which fully confirmed the earlier
+reports of the great damage which had been done. Although up to this
+time there had been some objection raised against the flights of the
+boys it must be said that after that event there was no one to criticise
+them.
+
+During the winter months not much was done excepting scout work, as the
+weather was too severe for the men in the trenches to attempt any
+advances, but as the spring months came on everything became more
+active, thus imposing greater duty on the air fleet.
+
+Not much of personal interest to the boys took place until May, when the
+great raid was planned to attack the munition factories and chemical
+works at and near Ludwigshafen, on the Rhine.
+
+"Ralph, did you hear that there is going to be a big expedition this
+week right into Germany?" said Alfred, who had been with the lieutenant
+at headquarters early one morning.
+
+"No, although the boys are always talking about something of that kind,"
+replied Ralph.
+
+"But this is a sure go; the lieutenant told me so a few minutes ago,"
+responded Alfred.
+
+"Is the lieutenant going, do you know?" asked Ralph.
+
+"Yes, I suppose that is why he told me about it," answered Alfred.
+
+"I wonder whether they will let us go with him?" asked Ralph.
+
+"Well, I didn't ask him, but I looked at him pretty hard, and I guess he
+knows how we feel about it," answered Alfred.
+
+The rumor turned out to be true, for the following day orders were
+formally received to prepare eighteen machines for a raid to the Rhine.
+The lieutenant announced the news to the boys, and added: "I suppose, of
+course, you wouldn't like to go on such a venturesome mission?"
+
+"Go!" exclaimed both boys in unison.
+
+The lieutenant laughed. "Well, if you insist on it I shall have to take
+you with me. The Seraph (which was the name of their airplane, although
+it was officially known as No. 47) will be fixed to carry a dozen bombs
+for the occasion."
+
+"But how about the quick firer?" asked Ralph.
+
+"We must dispense with that on this trip. Bombs are more valuable,"
+answered the lieutenant.
+
+"Well, aren't we going to take any guard ships along?" inquired Alfred.
+
+"Oh yes; six of the machines will be armed, but we must use every ounce
+we can carry on the Seraph. Before starting we must go over the route,
+as similar instructions will have to be issued to all of the flyers,"
+remarked the lieutenant.
+
+"Do you know where we are to go?" asked Ralph.
+
+"The objective point is Mannheim on the Rhine. The river is eighty miles
+due east, and Mannheim is about fifty miles farther down the river. That
+city is on the eastern bank of the river, and Ludwigshafen is a small
+town, on the opposite shore where the great laboratory of Badische
+Analin and Soda Fabrik is located," remarked the lieutenant.
+
+"So we are going to destroy a soda factory?" said Ralph with a grin.
+
+"Not exactly," replied the lieutenant, amused at the intimation. "The
+principal thing turned out at the plant before the war was nitrate, a
+chemical most essential in the manufacture of explosives, and the
+importance of the place may be understood when I tell you that fully
+two-thirds of this product used by the Germans comes from that place."
+
+"When will the start be made?" asked Ralph excitedly.
+
+"Tomorrow," was the reply.
+
+"Then I want to see the map," said Ralph.
+
+"By all means," answered the lieutenant. "Now, you will notice that here
+is a canal shown on the map which runs due east. That is the
+Rhine-Marne, which parallels this river, the Zorn. The Zorn flows into
+the Rhine at Strassburg. You know, of course, that rivers, or canals,
+are the best guides for our purposes, so we must get these firmly fixed
+in our minds."
+
+"Yes, that and the towns are sure to carry us along without mistake,"
+remarked Alfred. "What is that place, Saarburg? It is on the river."
+
+"That is an ancient town, and you can hardly fail to recognize the
+place, for it is surrounded by a great stone wall. It also contains a
+strong garrison. Now note the next important place, twenty miles farther
+on; that is Zabern. From that place we can see the Rhine at various
+places, as we intend to fly at an altitude of two thousand meters, or,
+as you would say, 6500 feet."
+
+"Why is it necessary to go to such a high altitude?" asked Alfred.
+
+"Because at Saarburg, Zabern and Brumath they have long range
+anti-airship guns, and we cannot take any chances," replied the
+lieutenant.
+
+The camp was a seething place of excitement the following morning.
+Twelve of the machines carried bombs exclusively; some of the airplanes
+had six bombs, each weighing 180 pounds; one had three bombs of 300
+pounds each, and the Seraph carried ten 120-lb. high-explosive
+cylinders.
+
+These were placed in a suitable case having compartments, the lower ends
+of the compartments being provided with outwardly opening doors, capable
+of being released by the pressure of the foot operating against a
+lever.
+
+"I am going to rig up the cameras so we can take pictures of the
+explosions," said Alfred, as they made their way to the hangar.
+
+"That is a splendid idea," remarked the lieutenant. "Such an enterprise
+would be commended by the Intelligence Department of the War Office. By
+all means make the arrangements, for we expect to start in an hour."
+
+Alfred rushed over to the supply depot, and soon had the cameras in his
+possession, together with extra rolls of films. Ralph accompanied the
+lieutenant to the hangar to note the placing of the bombs.
+
+"Why are the bombs placed with the pointed ends up?" asked Ralph, as the
+men were placing them in position.
+
+"So the fulminate cap can be placed on, preparatory to launching,"
+remarked the foreman.
+
+"Why, won't they go off without the cap on? Wouldn't a concussion
+explode them?" he asked.
+
+"Well, it would require a pretty tough jar to make them go off," replied
+the man.
+
+At the appointed time the eighteen machines arose, and started for the
+east. The sun was full in their faces, but the misty weather made it
+look like a great red ball, symbolic of the day's work. It was hard to
+get away from the glare of the sun as they arose to the height which the
+orders compelled them to take, and at Saarburg some of the machines were
+actually hit by missiles from the anti-airship guns.
+
+The first city of importance to greet their eyes, after leaving
+Brumath, was Lauterbach, and then Karlsruhe, a city of over 100,000 was
+sighted.
+
+"We are now thirty-five miles from Ludwigshafen," shouted the
+lieutenant, through the tube. "Keep well to the west of the river, and
+maintain the same height, until the city is reached."
+
+Two miles before Mannheim was reached eight of the machines swerved to
+the right, and crossed the river, their destination being the town of
+Oppau, several miles beyond the town, where large manufacturing
+establishments were turning out ammunition.
+
+"We are bound for the chemical factories," said the lieutenant. "See the
+workmen running about. They have, no doubt, heard of our mission by this
+time."
+
+"Which way shall I point the camera?" asked Alfred.
+
+"Straight down," replied the lieutenant. "I am going to signal No. 62 to
+take the lead, so we will be the fifth in line. That will give you a
+splendid opportunity to notice the effect of the explosions and to snap
+them."
+
+The lieutenant set the signal, "echelon formation," which means step
+formation, one machine being ahead and a little to the right or to the
+left of the succeeding one. In that manner the ten machines flew along,
+the distance between them being about eight hundred feet, and by this
+arrangement each succeeding machine was able to observe the effect of
+the bomb dropped by the machine ahead.
+
+Mannheim was avoided, and the machines steered straight for the chemical
+headquarters on the left side of the stream where No. 62 released the
+first bomb. Alfred strained his eyes, and saw a flash below. It missed a
+building, and he shouted the information to Ralph through the tube.
+
+"If that had gone a hundred feet to the right it would have taken a
+dandy building,--there, the second shot did it; that came from old
+Spic's machine; whew-w-w, but look at it! That smoke is as black as
+coal,--must be lots of chemicals there. Another,--and the second
+building smashed to flinders. The lieutenant is going to drop the first
+one,--down she goes! I took two fine ones just now. I'll bet the last
+picture will show it up just as it happened. Two more snaps. We are
+going to turn and go back. 62 is making the circle." Thus Alfred
+graphically described the first trip over the doomed town.
+
+A dense cloud was now coming up, or, rather, bunches of them in various
+places where the missiles struck, and just as the Seraph was making the
+turn a tremendous explosion was heard, which actually seemed to jar the
+machine. Alfred arose from his seat, and the lieutenant's tense face
+showed that something unusual had happened, as he gazed below. All the
+buildings were emptied and scores of operatives were lining up along the
+river bank, and moving toward the great bridge south of the works.
+
+"Did you notice that big explosion?" asked Alfred through the tube.
+
+Ralph nodded his head affirmatively.
+
+"That hit the largest building in the place, and there isn't much left
+of it. Did you see that tall chimney at the left side of the town? Well,
+that looks just like a big cannon with the smoke and fire coming out of
+it," commented Alfred.
+
+The ten ships crossed the town twice, discharging all their bombs, but
+they waited in the air for twenty-five minutes until the first of the
+detached airplanes from the north appeared. During this time there was
+plenty of opportunity to see the extent of the damage which had been
+done to the great factories.
+
+At a signal the airplanes, constituting the squadron, were lined up in
+two columns, and before they had proceeded far the signals told the
+success of that part of the squadron which had gone to Oppau. The signal
+was now set for "Home," and the machines, by this time lightened of
+their missiles, made a tremendous speed, until after they left the
+Rhine, and were making the last lap of the journey, when the machine
+carrying Captain De Goye and his Adjutant Buanau-Varilla, was forced to
+descend, owing to an accident.
+
+The different machines circled around, hoping to be able to render
+assistance, but shortly after the airplane landed it was discovered to
+be in flames, and it was conjectured that seeing relief was out of the
+question the aviators had destroyed the machine to prevent its being of
+any use to the enemy.
+
+
+
+
+CHAPTER XIV
+
+A TERRIBLE FIGHT IN THE CLOUDS
+
+
+The return to the base with only the single mishap alluded to was cause
+for congratulations, and the lieutenant came in for a large share of the
+commendation.
+
+In turn he prepared a special report setting forth the work done by the
+boys on the eventful journey. He pointed out that Ralph piloted the
+machine the entire distance, giving him, as the commanding officer of
+one division, time to direct the operation of the machines and attend to
+the bombs, while he had the pleasure of presenting to the authorities a
+set of unique photographs taken by Alfred at the very time the bombs
+were thrown and exploded.
+
+When the roll was called, two days thereafter, the men of the squadrons
+were lined up, an officer from headquarters passed down the line, and,
+among other places, halted before the boys, who stepped forward. On the
+breast of each was pinned a medal, and as the officer did so he kissed
+them on the cheeks, a custom which is faithfully observed, in accordance
+with the regulations, whenever a merit order is bestowed.
+
+There was a cheer as the two blushing boys stepped back to the line, and
+there were no prouder hearts than theirs as they heard the encomiums
+expressed on all sides for their bravery and devotion to duty. It was a
+pleasure to many other young Americans, who, like them, were volunteers
+serving in the aviation corps, and many of whom were afterwards also
+honored in like manner.
+
+There was hardly a day that there was not some experience added to their
+store of knowledge pertaining to airships, and the work connected with
+flying, all of which was performed with efficiency and credit.
+
+But the work which they performed was not all a series of jolly
+excursions without the corresponding sorrows. The devotion of Lieutenant
+Guyon to them dated from the time when that brave officer was stricken
+while on a trial flight from the camp at Bar-le-Duc. He never forgot how
+they took charge of the machine, and brought it safely to earth and
+cared for him so tenderly. Thereafter, it was rarely the case that he
+went aloft without one or both of the boys in his company.
+
+Shortly after the foregoing events, while the three were performing
+scout duty north of St. Mihiel, they were attacked by two German
+machines, an Albatross and a Taube, a combination which, especially when
+operating against a single machine, is capable of doing deadly work.
+
+When the two enemy ships were sighted, Alfred was in the pilot's seat,
+and under the direction of the lieutenant, the airplane shot forward
+directly in the path of the first machine, while the lieutenant poured
+out a constant storm of shot. The Albatross dived, and Alfred at once
+moved the control to ascend, thus bringing their machine above the
+Taube.
+
+The object now was to so manoeuver their ship as to keep between the two
+enemies, and in doing so make it difficult for either of them to use the
+quick firers without danger of hitting the other. The Seraph was a rapid
+climber, due to the high power of her engines.
+
+"Send her up as rapidly as possible," shouted the lieutenant. "Keep on
+going, and turn slowly to the left, so as to make a big circle; that
+will give me a chance to put in some shots."
+
+Alfred knew the manoeuver, the purpose being to bring the two machines
+into line with each other, and thus enable the lieutenant to get his gun
+in the range of both machines.
+
+"A little down now, and more to the right; there, steady," was the next
+command.
+
+"Br-r-r-r-r" sounded the gun, as the officer turned the crank.
+
+"The Taube is going down," cried Ralph excitedly, "and here comes
+another of the same kind," continued Ralph.
+
+"Go straight for the second one," shouted the lieutenant, and Alfred
+knew that the same trick had to be repeated.
+
+But the new arrival did not accept the invitation to fight on the lines
+that the first machine adopted. Instead, it began to circle about at a
+safe distance, endeavoring to secure the overhead position.
+
+"Follow that bird," said the lieutenant, "and keep going. They will
+learn something about high flying before they get through with us."
+
+The Albatross was not making much headway in the climbing game. On the
+other hand, the new Taube was an extraordinary flyer.
+
+"There is only one man aboard of her," said the lieutenant. "Take the
+glasses, and see if you can make out her number."
+
+Ralph studied the machine for some time. "I am not sure," he said, "but
+I think it is D 28. No one but the pilot is aboard."
+
+"That's good. He can't hit us head on. Trail him or get ahead of him and
+keep on ascending," said the lieutenant, now preparing his rapid firer
+with a new charge.
+
+The Taube suddenly swerved to the right, and let loose a full charge
+from his gun. It seemed as though one side of the Seraph had the
+covering of the planes ripped off, for the hail of bullets tore right
+through the frame. Alfred shook his head as he cleared away several bits
+of wreckage.
+
+"How high are we?" asked Ralph.
+
+"Two thousand six hundred meters," was the reply.
+
+The lieutenant had his revenge, however, for their own machine was now
+creeping up and gradually getting a rear position. This was what he had
+been aiming for. The stream of shots from the Seraph's gun now began to
+tell. In one despairing attempt the Taube turned fully half way around
+and answered, but it was evident that something was wrong with the ship.
+
+Suddenly the Seraph darted down. Ralph and the lieutenant looked back in
+surprise. Alfred's head had dropped to one side, and one arm hung over
+the side of the chassis.
+
+The lieutenant leaned over and caught the elevating rudder, not a moment
+too soon, and corrected the machine. Ralph leaned over the side of the
+body, and drew Alfred toward him, as the lieutenant climbed into the
+aviator's seat. All this took but a moment's time, but meanwhile it was
+necessary for them to observe the enemy and avoid him.
+
+"The Taube is falling," cried out Ralph, "but the Albatross is swinging
+around."
+
+Before it was possible to correct the machine, and avoid the danger, the
+gunner of the oncoming aeroplane began to pump, and the shot began to
+tell on the Seraph's framework. The lieutenant now saw that it would be
+a terrific task to get above the Albatross, so turning the control
+rudder sharply, the Seraph made a quick slide below its adversary.
+
+Alfred did not move, and Ralph tried to control himself, for in the
+great excitement attending the above circumstances, he was almost
+distracted. He was leaning partly over the body of the machine when the
+lieutenant saw him crouch forward. He put his hand on the boy and tried
+to shake him, but there was no response.
+
+Down, down went the machine, still under absolute control of the
+lieutenant, who turned the machine in a circle in order to be sure to
+bring it down within the French lines. When within five hundred feet of
+the earth something seemed to go wrong with the steering mechanism. The
+lieutenant tugged and pulled the lever back and forth. The machine
+refused to move forward in a straight line, and landing while the
+machine is describing a circular movement is a most dangerous manoeuver.
+
+Both boys were quiet, and the lieutenant feared for the worst. A hundred
+feet more and all would be over. In desperation he banked the machine to
+stop its terrific speed. This helped the situation, but did not prevent
+the spinning motion, and finally the crash came.
+
+They landed in a newly ploughed field, the worst possible sort of place
+for a disabled machine. The lieutenant and Ralph were thrown out of
+their seats, but Alfred was held fast in the machine.
+
+Many willing helpers were on hand, and they found all three of the
+flyers were unconscious when put into the van, but, fortunately, they
+were within a half mile of the emergency hospital south of St. Mihiel.
+On the way to the hospital a hurried survey was made to ascertain the
+extent of the injuries, but the physicians were silent.
+
+Alfred regained consciousness before the hospital was reached. The
+doctors said that there was a severe bruise on the back of his head, as
+though he had been struck by some heavy object. The lieutenant opened
+his eyes, as he was placed on the operating cot. He glanced around
+wildly for a moment, and then asked: "Where are my boys!"
+
+"We have them here; they are all right," said a nurse.
+
+He forced a weak smile, turned his head to one side, and was quiet.
+
+Ralph had been shot through the body, too high up, it was believed, to
+touch the lungs. A second bullet had passed through the fleshy part of
+the left arm, and he was very weak from loss of blood. The three were
+placed on adjoining cots after the first examination was over, and after
+all had regained their normal senses a pair of stretcher bearers entered
+the door, and bore a wounded man to one of the adjoining cots.
+
+The lieutenant was the first to observe the chevrons on the sleeve of
+the patient, and that he was a German. Ralph tried to raise up as he
+noticed them carefully lift the wounded man, and deposit him on the cot.
+
+"That's the fellow who piloted the last Taube; I'm sure of that. He's
+the fellow I saw through the glasses," said Ralph.
+
+Inquiry quickly established the truth of Ralph's observation. His
+machine had fallen within French lines, and not far from the place where
+the Seraph struck. It was an odd coincidence.
+
+The lieutenant was the most severely injured, how badly no one knew at
+the time, for a certain time must elapse before the full extent of the
+injury in such cases develops. The next morning the boys were informed
+that the lieutenant was much worse, and then for two days they had no
+news.
+
+Meanwhile, Ralph's wounds were healing, and no excessive fever
+developed. Alfred's spine seemed to be affected by the terrific blow,
+but that would be all right again in course of time.
+
+The sad intelligence came to them a few days thereafter that the
+lieutenant had died. It was, indeed, a grief to them. They had grown to
+love him as a friend, and they understood each other so well. It was
+learned that his heart was too weak to bear up against the internal
+injuries, which he received when the machine struck the earth.
+
+It was two weeks before the boys were able to leave the hospital, and
+they were then not able to return to duty. The shock of their friend's
+death was so acute that, as Ralph expressed it, they never again wanted
+to see an airplane.
+
+They were soon sent to Paris to recuperate, and while there they formed
+plans which took them into another part of the great war game, and we
+may be able hereafter to follow them in their new exploits.

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive

+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at

+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
