Daviess, Carroll, Ogle and LaSalle counties. +The only grove of this beautiful tree in Illinois is in the +White Pines Forest State Park near Oregon, Ogle County, where +there are trees over 100 years old that have attained a height of +90 feet with a diameter of 30 inches. This tree formerly formed +the most valuable forests in the northeastern United States, +stretching from Maine through New York to Minnesota. The +straight stem, regular pyramidal shape and soft gray-green +foliage made it universally appreciated as an ornamental tree and +it has been freely planted throughout the State.</p> + +<p>The <i>leaves</i>, or needles, are 3 to 5 inches in length, bluish-green +on the upper surface and whitish beneath, and occur in +bundles of 5, which distinguishes it from all other eastern pines. +The pollen-bearing <i>flowers</i> are yellow and clustered in cones, +about ⅓ inch long at the base of the growth of the season. The +seed-producing flowers occur on other twigs and are bright red +in color. The cone, or <i>fruit</i>, is 4 to 6 inches long, cylindrical +with thin usually very gummy scales, containing small, winged +seeds which require two years to mature.</p> + +<p>The <i>wood</i> is light, soft, durable, not strong, light brown in +color, often tinged with red, and easily worked. It was formerly +much used in old colonial houses where even the shingles were +of white pine. It is excellent for boxes, pattern making, matches, +and many other products.</p> + +<p>Its rapid growth and the high quality of the wood make it one +of the best trees for reforestation on light soils in the northern +part of the State. The white pine blister rust was introduced into +America about 35 years ago, and has since become widespread +and highly destructive of both old trees and young growth.</p> + +<div class="blockquot"><p>The Austrian pine, <i>Pinus nigra</i> Arnold, has been naturalized in Lake +County and has been planted as an ornamental tree throughout the State. +Its leaves in 2’s, from 3 to 5 inches long, stiff and dark green.

It forms forests on light sandy soils +in Tennessee, Arkansas, Oklahoma and Texas. At maturity, the +tree has a tall, straight stem and an oval crown, reaching a +height of about 100 feet and a diameter of about 4 feet.</p> + +<p>The <i>leaves</i> are in clusters of two or three, from 3 to 5 inches +long, slender, flexible, and dark blue-green. The cones are the +smallest of our pines, 1½ to 2½ inches long, oblong, with small +sharp prickles, generally clustered, and often holding to the twigs +for 3 or 4 years. The <i>bark</i> is light brownish-red, broken into +rectangular plates on the trunk but scaly on the branches.</p> + +<p>The <i>wood</i> of old trees is rather heavy and hard, of yellow-brown +or orange color, fine grained and less resinous than that +of other important southern pines. It is used largely for interior +and exterior finishing, general construction, veneers, paper pulp, +excelsior, cooperage, mine props, and other purposes. The tree +transplants readily, grows rapidly, succeeds on a variety of soils +and has proved valuable for reforestation.</p> + +<div class="blockquot"><p>A few trees of jack pine, <i>Pinus banksiana</i> Lamb., are found in Lake +County. It is a small northern tree with leaves about an inch long, borne in +2’s, with cones about 2 inches long. It is planted for reforestation in the +State. The Scots pine, <i>Pinus sylvestris</i> L., has been freely planted in Illinois +and may be known by its orange-brown bark and its twisted leaves 2 to 3 +inches long, arranged in 2’s. It has become naturalized on the sand dunes +in Lake County.</p> + +<p>The Norway spruce, <i>Picea abies</i> Karst., has been freely planted +throughout the State. It forms a dense conical spire-topped crown and +reaches a height of 50 to 70 feet. The leaves are needle-shaped, about an inch +long, dark green, and persist for about 5 years.

Its straight trunk with numerous ascending +branches, and narrow conical outline makes the tree one of +considerable beauty. In old age, the tree generally has a broad +fluted or buttressed base, a smooth slowly tapering trunk and a +broad, open, flat top of a few heavy branches and numerous +small branchlets. The original-growth timber attained heights +of 80 to 130 feet and diameters of 5 to 10 feet.</p> + +<p>The <i>bark</i> is silvery to cinnamon-red and finely divided by +numerous longitudinal fissures. The <i>leaves</i> are about ½ to ¾ +of an inch in length, arranged in feather-like fashion along two +sides of small branchlets, which fall in the autumn with the +leaves still attached.</p> + +<p>The <i>fruit</i> is a rounded cone, or “ball”, about one inch in +diameter, consisting of thick irregular scales.</p> + +<p>The <i>wood</i> is light, soft, easily worked, varies in color from +light to dark brown, and is particularly durable in contact with +the soil. Hence it is in demand for exterior trim of buildings, +greenhouse planking, boat and shipbuilding, shingles, posts, poles +and crossties.</p> + +<div class="blockquot"><p>The tamarack, or American larch, <i>Larix laricina</i> K. Koch, resembles +the bald cypress in growing in swamps and in shedding its leaves in autumn. +This tree is found in Illinois growing in bogs in Lake and McHenry counties. +The leaves are flat, soft, slender, about one inch long and borne in clusters. +The cones are only ½ to ¾ inch long. The European larch, <i>Larix decidua</i> +Mill., may be distinguished from the native species by having slightly longer +leaves and larger cones that are more than an inch long.</p></div> + +<div class="figcenter" style="width: 400px;"><img src="images/ornament.png" width="400" height="18" alt= +"ornament" title="" /><span class='pagenum'><a name="Page_7" id="Page_7">7</a></span></div> + +<h4><b>RED CEDAR</b> <i>Juniperus virginiana</i> L.</h4> + +<p><span style="float: left; font-size: 2.8em; line-height: .8em; padding-top: 0px; padding-right: 2px; padding-bottom: 0px;">R</span>ED cedar, the most plentiful coniferous tree in the State, is +very valuable, growing on a great variety of soils, seeming +to thrive on hills where few other trees are found.

It was organized +at that time as a result of an increased need for proper forestry +practices within the State on the part of the owners of timber +land and potential timber lands.</p> + +<div class="blockquot2"> + +<p>The objectives of the Division are as follows:</p> + +<p class="indent">1. To promote and assist in the reforestation of idle lands +unfit for agriculture.</p> + +<p class="indent">2. To prevent and control woods fires.</p> + +<p class="indent">3.

To assist Illinois farmers, landowners, and corporations +in woodland management practices.</p> + +<p class="indent">6. To assist in the establishment of county and community +forests.</p> + +<p class="indent">7. To disseminate forestry knowledge through the publication +of forestry literature.</p> + +</div> + +<h4><b>Reforestation</b></h4> + +<p>Illinois has within its total land area of approximately +35,800,000 acres, 2,500,000 acres of land that should be reforested. +These lands are lying idle at present due to the fact that +they are too poor for agricultural purposes. As such they provide +an economic burden to their owners and to the State because +they are unproductive. These same lands will grow trees profitably, +therefore, it is necessary that they be planted to trees for a +future timber crop which ultimately will bring a revenue to the +landowners and community.</p> + +<p>To meet this situation, the Department of Conservation, +Division of Forestry has developed two large forest tree nurseries +capable of producing 15,000,000 trees annually for reforestation +and erosion control purposes. These trees are available to +farmers and landowners at prices varying from $5.00 to $15.00 +per thousand, dependent upon the species of trees desired. Trees +secured from the State must be used only for reforestation and +erosion control and cannot be used for landscape or ornamental +plantings.</p> + +<p>Definite progress has been made in the State reforestation +program of idle lands. The first major distribution of trees took +place in 1936 at which time 300,000 trees were planted in the +State. Since 1936 the State’s reforestation program has steadily<span class='pagenum'><a name="Page_68" id="Page_68">68</a></span> +been enlarged to the extent that in 1940, 6,250,000 trees were +distributed from State nurseries and in 1954, 9,996,000 trees left +the Division’s nurseries to be planted by farmers and public +agencies in the State.</p> + +<p>Considerable progress has been made, however, it is hoped +that the reforestation program in Illinois will continue to expand +until all idle lands in Illinois are growing a useful timber crop.</p> + +<h4><b>Forest Fire Protection</b></h4> + +<p>Woodland fires in Illinois always present a serious problem +to the future growth and quality of our forests. Thousands of +dollars worth of damage is done annually to our existing woodlands +by fires which not only destroy our merchantable timber +but also cause severe mortality to young forest seedlings. Fires +seriously affect the soil, destroy wildlife and disrupt the entire +biological balance of the forest. Every effort should be made, +therefore, to prevent woods fires.</p> + +<p>In 1938 the State Division of Forestry inaugurated a program +in forest fire protection. Since that time ten fire protection +districts and a forest fire protection headquarters have been +established in southern Illinois. Fire fighting personnel has been +hired, radio communication established, and ten State forest +fire towers have been erected. Fire protection has been established +on all State forests. Necessary tools and equipment for use +by both forestry personnel and volunteer groups have been purchased. +As a result, 3,674,000 acres of State and private land are +now receiving fire protection. This program will be enlarged as +funds permit until all woodland acreage in need of protection +will receive necessary fire protection.</p> + +<p>Our forest resources are a valuable asset to Illinois and one +of the most valuable renewable resources that we have. They can +only be so, however, if adequate forest fire protection is afforded +them.</p> + +<h4><b>Woodland Management</b></h4> + +<p>Illinois’ total forest acreage, when our first settlers came to +the State, included 15,273,000 acres of the finest timber to be +found in the Middle West. This represented 42 per cent of the +total acreage. Although Illinois today is considered strictly an +agricultural State, at one time we were rich in forest resources +and they were the State’s most valuable asset. Today Illinois +has but 3,996,000 acres of woodlands of which 92% is in private +ownership. The trained foresters of the Division of Forestry +are making every effort to assist farmers and landowners in +their woodland management problems. It is vitally necessary +that proper forestry practices be conducted on our woodlands +today in order that the landowners realize an income from their +forest lands and thereby make them an asset rather than a +liability. Advice on woodland management is available free of +charge from the Division.</p> + +<p><span class='pagenum'><a name="Page_69" id="Page_69">69</a></span>The marketing and proper utilization of our existing forest +resources is the concern of the Division of Forestry. Approximately +1,000 small sawmills are operating in the State and, of +course, much timber is needed annually to keep such mills in +operation. Every effort is being made to advise timber landowners +as to proper cutting practices and disposal of merchantable +timber.</p> + +<h4><b>State Forests</b></h4> + +<p>The State at present has 10,110 acres in State forests. It is +hoped that this acreage can be enlarged in future years as State +appropriations permit. The above acreage includes three State +forests located in Union, Mason and Henderson counties. Illinois +State forests will always be smaller than those of other states because +of the unavailability of low valued land. The Division’s +proposed State forest plan provides for a large number of small +State forests throughout the State which would serve as ideal +examples of proper woodland management and reforestation +practices. As funds permit these will be acquired in the future.</p> + +<p>Our State forests provide ideal recreational areas at present +and thousands of visitors use them annually. In addition, as the +timber matures on them, they will provide a revenue from timber +sales and become self-sustaining.</p> + +<h4><b>Community Forests</b></h4> + +<p>Community forests are the oldest type of forest lands in +public ownership. Some have been in existence for 200 years in +the eastern states and records of older community forests have +been found in some of the European countries. The Division of +Forestry is cooperating with counties and communities in an +effort to get a large scale community forest program in Illinois. +To date there are 58 community forests having a total acreage +of 52,296 acres. Up to the present time 700,000 trees have been +planted on these areas in cooperation with the Division of +Forestry.</p> + +<p>Nine counties in the State have County Forest Preserve +Districts at present. The ratio of ten acres for each 1,000 +population within the county appears to be a fair goal for county +forest preserve systems in accordance with the Illinois State +Planning Commission. On this basis 19 counties in Illinois should +have forest preserves.</p> + +<h4><b>Summary</b></h4> + +<p>As a result of increased appropriations for forestry in recent +years a definite well-planned forestry program is in effect in +Illinois.

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 +Foundation + +The Project Gutenberg Literary Archive Foundation is a non profit +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 +http://pglaf.org/fundraising.

Newby + Chief Executive and Director + gbnewby@pglaf.org + + +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: + + http://www.gutenberg.org + +This Web site includes information about Project Gutenberg-tm, +including how to make donations to the Project Gutenberg Literary +Archive Foundation, how to help produce our new eBooks, and how to +subscribe to our email newsletter to hear about new eBooks. + + +</pre> + +</body> +</html> diff --git a/37646-h/images/bcover.jpg b/37646-h/images/bcover.jpg Binary files differnew file mode 100644
