At -Gehzireh, the gardens of the Khedive of Egypt at Cairo, it has been -known to grow nine inches in a single night. At Syon House, the Duke -of Northumberland's, stems of "<i>Bambusa Gigantea</i>" have attained -the height of 60 feet in 12 weeks; and I have made "<i>Paper-Stock</i>" -from a stem of "<i>Bambusa Vulgaris</i>," sent me by Dr. Hooker, from the -Royal Botanical Gardens at Kew, which, as measured by the gardener in -the Palm-house, grew at the rate of three feet in a single week; at -Chatsworth, the Duke of <span class="pagenum"><a id="page4"></a>[p.4]</span> Devonshire's, this same variety (the -"<i>Bambusa Vulgaris</i>") has attained the height of 40 feet in 40 days.</p> - -<p>Throughout the East Indies the "Bamboo" flourishes, forming indeed -in many districts impenetrable jungles. It grows abundantly also in -the West Indies, in Central and South America, the Brazils, in Africa -and Asia; in China especially, and in Japan, the plant is indigenous, -and the natives cultivate it carefully, employing it for almost every -article of convenience and luxury; in fact, wherever heat and moisture -exist, some species of the "Bamboo" will be found, or may be readily -cultivated.</p> - -<p>Attempts have from time to time been made in England, and elsewhere, to -obtain from the "<span class="smcap">Bamboo</span>" "<i>Half-stuff</i>" or "<i>Pulp</i>" suitable -for the manufacture of paper, and paper indeed has been made therefrom, -but hitherto these attempts have neither industrially nor commercially -attained successful results, and for the following reasons.</p> - -<p>Hitherto the "<span class="smcap">Bamboo</span>" has been collected and treated in a -condition more or less of maturity, or without regard to its age; -and when the plant has attained its full growth the woody fibre is -extremely dense and indurated; when old, indeed, the exterior portion -of the stem of many varieties of the plant becomes so hard and -silicious that it will, like flint, strike fire with steel.</p> - -<p>Owing to the presence of this large quantity of silica, and the -extreme hardness of the stem when <span class="pagenum"><a id="page5"></a>[p.5]</span> developed and matured, it -has been found by all those who have hitherto experimentally treated -"<span class="smcap">Bamboo</span>" that the only possible means of converting it into -<i>Pulp</i> for Paper-making, has been to subject it to long-continued -boiling, or digesting, in very strong solutions of caustic alkali, at -an elevated temperature—in other words, at or under a pressure of ten -to eleven atmospheres (150 to 160 lb. pressure per square inch)—by -which means a <i>Pulp</i> has certainly been produced, but at a great cost, -and the danger and practical difficulties of working under such high -pressure, have deterred further progress in this direction.</p> - -<p>I have found that when the stems of "Bamboo," are cut down at an early -stage of their growth, when the plant is full of sap, and before the -cellulose or cellular tissue, and the lignine have become indurated, -and silica deposited; while, in fact, so to speak, the plant may be -termed a succulent vegetable, and before it has become converted into -wood, that a very mild system of treatment in successive weak alkaline -baths, at atmospheric pressure only, suffices to decompose and render -soluble the mucilaginous and other extractive compounds combined -naturally with the fibrous tissue of the plant, so that they may be -readily eliminated, or separated therefrom, by subsequent washing, -leaving the residuary fibres pure and free.</p> - -<p>A comparative illustration of the transitional stage of growth -above referred to, showing the conversion of succulent vegetable -fibrous tissue, into harsh woody <span class="pagenum"><a id="page6"></a>[p.6]</span> fibre, may be remarked with -"Asparagus," the young and green stems of which, are used as a delicacy -for the table, a few weeks further growth converting them into hard -woody fibre, which no amount of boiling would, or could, render -palatable; the "Asparagus," indeed, has its parallel in the "<i>Bambusa -Edulis</i>," a variety of "<span class="smcap">Bamboo</span>," the young stems of which are -eaten and considered very nourishing.</p> - -<p>The "<span class="smcap">Bamboo</span>," being an <i>endogenous</i> plant, (that is to say, -growing from inside) composed mainly of fibrous tissue, combined with -the ordinary sappy and other extractive matter common to all vegetable -growth, the stems do not require the elaborate preparatory manipulation -which is necessary to separate the fibrous, from the extraneous and -woody matter, which in <i>exogenous</i> plants (i. e. growing from, or on -the outside) must be removed, as it is only the true fibre which is -useable for Textile Manufactures.</p> - -<p>Such plants known to commerce as "<span class="smcap">Flax</span>," "<span class="smcap">Hemp</span>," -"<span class="smcap">Jute</span>," "<span class="smcap">Rhea</span>," &c. &c., after having become mature, -and being dried, have to undergo a process of retting, or steeping, -followed by scutching and heckling, in order to separate the ultimate -fibres from the woody stem and bark to which, while in their normal -condition, they are attached.</p> - -<p>The cost therefore, of producing merchantable fibre from this class -of plants is very considerable, and the produce or yield of fibre, -to the plant cultivated, very small, that of "<span class="smcap">Flax</span>" being -computed at from 5 to <span class="pagenum"><a id="page7"></a>[p.7]</span> 6 cwt., "<span class="smcap">Hemp</span>" 7 cwt., and -"<span class="smcap">Jute</span>" 5 to 6 cwt. per acre, "<span class="smcap">Cotton</span>" being much -less; "<span class="smcap">Bamboo</span>," as I will presently show, producing tons as -compared with cwts. of the foregoing, and, be it noted, with far less -cost for cultivation, and the subsequent preparation of the fibre.</p> - -<p>The stems of the "<span class="smcap">Bamboo</span>," cut young, as I propose to -use them, contain from 60 to 75 per cent. of moisture; it will be -obvious, therefore, that to ensure a regular and continuous supply, -under economical conditions, to a central factory for the manufacture -of "<i>Paper-Stock</i>," plantations would have to be formed contiguous -thereto, as practised with "<span class="smcap">Sugar Cane</span>," or in a similar -manner to Osier beds, in England.</p> - -<p>I have mentioned the latter, as in order to stimulate a rapid, aqueous, -and sappy growth, as also to provide for the dry seasons common to hot -countries, a system of irrigation would be necessary, such a system -indeed being at present practised with the <span class="smcap">Sugar Cane</span>, in -Egypt, Spain, and elsewhere.</p> - -<p>With plantations of "Sugar Cane," to which plant the "<span class="smcap">Bamboo</span>" -somewhat assimilates in character and growth, it is necessary, in order -to ripen the canes and develop saccharine, to allow free ventilation to -the growing plant, and thus the ground is not fully occupied; this would -not be the case with "<span class="smcap">Bamboo</span>," which should be planted and grown -closely together to favour the stems shooting upwards, as practised -<span class="pagenum"><a id="page8"></a>[p.8]</span> with "<span class="smcap">Hemp</span>" and "<span class="smcap">Flax</span>," where fine staple of fibre -is desired.</p> - -<p>By following such a system, the stools or roots once established, a -systematical and regular cropping, or cutting, would ensue, the stems -being all cut down simultaneously, by sections or beds, in regular -succession, numerous croppings annually would thus be obtained, and -when necessary, fresh beds would be formed, the older growth being -available for fuel for the manufactory.</p> - -<p>The Sugar Cane from the time of planting, to cutting, takes from nine -to twelve months to grow and mature; but even thus grown, the produce -of canes (ready dressed for the mill) generally ranges from 30 to -35 tons to the acre, it sometimes exceeds 40 tons; allowing several -crops or cuttings annually for the "<span class="smcap">Bamboo</span>," it may fairly be -assumed that at least this latter quantity would be obtained per acre.</p> - -<p>Allowing 208 feet square to represent one acre; divided into twelve -beds, each 96 × 26 feet, with twelve paths 96´ × 8´ 8´´ wide, and one -intersecting road 208 × 16 feet wide, leaves a space for planting equal -to 2496 feet, or 29,952 feet in the twelve beds; allowing the stems to -be 2 feet apart, and say only 12 feet high, we have 7488 stems, which -at 12 lb. each = 40 tons per acre.</p> - -<p>The stem of the "<i>Bambusa Vulgaris</i>" before mentioned, grown in -the Palm-house at Kew, was of an average size, 10 to 11 inches -circumference, and weighed green 1<sup>1</sup>/<sub>2</sub> lb. per foot run; and although -<span class="pagenum"><a id="page9"></a>[p.9]</span> no doubt by denser growth, induced by frequent cropping, the -stems even of the larger varieties of "<span class="smcap">Bamboo</span>" would decrease -in size, still an equal tonnage to the acre would be produced, with -longer joints or internodes, and a finer staple of fibre.</p> - -<p>The stems of the "<span class="smcap">Bamboo</span>" (<i>taken as dry</i>) treated by -my process, will yield 60 per cent. of unbleached <i>Fibrous</i> -"<i>Paper-Stock</i>," baled up in merchantable condition; assuming therefore -an annual cropping of 40 tons, green stems, which will lose 75 per -cent. moisture in drying, we have 10 tons dry stems per acre; these at -60 per cent. yield, will give 6 tons per acre of "<i>Paper-Stock</i>," an -enormous product as compared with any other fibrous material with which -I am acquainted.</p> - -<p>Allowing the plantation to be credited at the rate of 5<i>s.</i> per ton, -for the green stems, delivered to the central factory, and 40 tons to -be produced per acre, we have the sum of 10<i>l.</i> per acre to cover all -charges; once, however, the plantation formed, but little cost in the -way of cultivation need be incurred. The main outlay would be for rent, -irrigation, and cutting, and carrying to the manufactory.</p> - -<p>I may here remark that I propose where possible, to return to the -<i>Plantation</i>, mixed with the water employed for irrigation, the -mucilaginous and other extractive constituents, or matters, (amounting -to 40 per cent.) abstracted from the stems during the process of -manufacturing the "<i>Paper-Stock</i>," as Manure, thus maintaining -fertilization to the growing plant.</p> - - -<h3><span class="pagenum"><a id="page10"></a>[p.10]</span> <span class="smcap">Details of my System of Treating "Bamboo" for the -Manufacture of Fibrous</span> "<i>Paper-Stock</i>."</h3> - -<p>An essential point in my system for treating "<span class="smcap">Bamboo</span>" to -produce therefrom fibrous "<i>Paper-Stock</i>," consists in operating upon -the stems of the plant when young, and preferably when fresh, as, and -when, cut and collected.</p> - -<p>Brought therefore to a central factory in this condition, the stems -are passed through heavy crushing rolls, in order to split and flatten -them, and at the same time crush, or smash, the knots, or nodes. The -stems thus flattened, are then passed through a second series of -rolls, which are channelled, or grooved, in order further to split, or -partially divide them longitudinally into strips, or ribbons; these -being cut transversely, into convenient lengths by a guillotine knife -or shears, are delivered by a carrier, or automatic feeder, direct to -the boiling pans, or elsewhere, as desired.</p> - -<p>As the stems when fresh and green, contain from 60 to 75 per cent. -of sappy and mucilaginous matter, much of this is expressed by the -crushing, while at the same time the fibrous mass, being partially -disintegrated, is thus more readily acted upon in the succeeding -processes.</p> - -<p>If desired, the crushed stems may be dried and stored; such drying, -however, must be very carefully <span class="pagenum"><a id="page11"></a>[p.11]</span> conducted and watched to avoid -destructive fermentation.</p> - -<p>I have in the preceding "Remarks" referred to "<span class="smcap">Flax</span>," -"<span class="smcap">Hemp</span>," "<span class="smcap">Jute</span>," and similar <span class="smcap">Fibres</span> known -to commerce, such fibres being imported into this country in their -prepared condition, suitable for Textile purposes. They have, in fact, -passed through a process of semi-manufacture, such process, as I have -explained, being required to separate the ultimate fibres from the -interior woody stem to which when growing they are attached; and it is -obvious that it would not be (economically) possible to import any of -these fibrous plants as grown or produced, owing to their enormous bulk -in that condition.</p> - -<p>Now although the stems of the "<span class="smcap">Bamboo</span>," after cutting and -crushing, may, as I have shown, be dried (and will when dried give -a yield of 60 per cent. of fibre), still their bulk and extreme -lightness would preclude importing them to this country in their <i>raw</i> -condition, not merely from their heavy cost for carriage, but from -their liability to damage from fermentation. For these economical -considerations, therefore, I propose to reduce the "<span class="smcap">Bamboo</span>" -into "<i>Fibrous-Stock</i>" where grown or produced.</p> - -<p>It may be well, before entering into details of the process, briefly to -explain the ordinary system employed for preparing fibres, or fibrous -materials, as also rags, for Paper-making. This consists in sorting, -cutting, cleaning, and, if need be, roughly opening them, followed by -boiling in alkaline leys, after which <span class="pagenum"><a id="page12"></a>[p.12]</span> they are well washed -until cleansed from impurities in what is technically termed the rag -or breaker engine, during which operation they are disintegrated or -reduced into "<i>Half-stuff</i>," or <i>semi-pulp</i>, this being subsequently -bleached and converted into pulp and paper.</p> - -<p>As the object of my process is to produce a fibrous or tow-like -<i>Stock</i>, retaining as far as possible the normal or natural condition -of the fibre, and not "<i>Half-stuff</i>" or "<i>Pulp</i>," my system of -treatment differs materially from the foregoing, more especially in the -boiling and washing processes.</p> - -<p>Both of these processes I conduct in a battery, or series of vessels -(16, 20, or more in number), such vessels being connected together -by pipes, or channels, furnished with valves, or cocks, so that -communication between the individual vessels may be maintained, -disconnected, and regulated as desired, in such manner that the -vessels, being methodically charged in succession with the material to -be operated upon, the heated leys (composed of caustic alkali) can be -progressively conducted from vessel to vessel of the series, passing -over and through the material placed therein.</p> - -<p>The leys are thus used again and again, (each successive change, or -charge of ley, carrying forward the extractive matters it has dissolved -from the fibre with which it has been in contact) until exhausted or -neutralized, (when they are discharged), fresh leys being methodically, -and successively, supplied, until by degrees, the extractive matters -combined with <span class="pagenum"><a id="page13"></a>[p.13]</span> the fibre or fibrous material have been -rendered sufficiently soluble, when hot water for washing, or rinsing, -is in the same continuous manner run successively from vessel to -vessel, over, and through, the material contained therein, until the -extractive matters rendered soluble by the previous alkaline baths -have been carried forward and discharged, leaving the residuary fibre -sufficiently cleansed.</p> - -<p>By this system of boiling in continuity, until all the effective -alkali in the leys is exhausted or neutralized, I realize an economy -of from 30 per cent. to 40 per cent. of soda over the ordinary process -of boiling, and by the subsequent washing, or rinsing, in the same -continuous manner, without removing the material from the vessels, the -normal structure of the fibre is in a great measure retained, waste is -minimized, and thus, while being thoroughly cleansed and freed from -extraneous matter, the strength and staple of the fibre are preserved; -a considerable saving of fuel results from the heated liquors being -used again and again, less steam being required, as also less water, -while at the same time economy of both labour and power is effected -over the ordinary system.</p> - -<p>Assuming the boiling and succeeding washing processes to be concluded, -and the material ("<span class="smcap">Bamboo</span>") in one of the vessels of the -series in its regular succession, to be found sufficiently treated and -cleansed, a final cooling water is run on and through the fibre, which -is then drained, and the contents of the vessel (disconnected for the -time being from the series) <span class="pagenum"><a id="page14"></a>[p.14]</span> emptied into a waggon running on a -railway, by which it is conducted to a press or otherwise to abstract -all the remaining moisture possible.</p> - -<p>The dry, or semi-dry fibre, is then submitted to the action of a -willow, or devil, by means of which it is opened or teazed out, and -converted readily into a tow-like condition, when it is dried by a -current of heated air, induced by a fan-blast, and finally baled up -for storage or transport, in a similar manner to <span class="smcap">Cotton</span> or -<span class="smcap">Jute</span>.</p> - -<p>In this condition of "<i>Paper-Stock</i>," it may be kept an indefinite -length of time without injury, and when received by the -Paper-manufacturer requires merely soaking down and bleaching, to fit -it for making into paper, either by itself, or used as a blend with -other materials, as desired.</p> - -<p>The minuter details of my process for treating raw fibres, or fibrous -material, for the manufacture therefrom of <i>Fibrous</i> "<i>Paper-Stock</i>," -are fully described in my several Patents, the only variation so far -as relates to "Bamboo" being the preliminary preparation of the young -stems, the other portions of the process being substantially the same -as in daily operation at the Ford Works, Sunderland, for the treatment -of "Esparto," and other "<i>raw fibres</i>."</p> - -<p>I have only now further to remark that the "Plant" required to -manufacture "<i>Paper-Stock</i>" from "Bamboo" on an economical and -practical working scale, would consist of a battery of boiling pans, -with the other necessary adjuncts and machinery, <span class="pagenum"><a id="page15"></a>[p.15]</span> steam engines -and steam boilers, such "Plant" being on a scale adequate to the -manufacture of 100 tons "Bamboo" weekly, producing therefrom say 60 -tons merchantable "<i>Paper-Stock</i>."</p> - -<p>As the above scale of operations, viz. the Manufacture of 100 tons -("<span class="smcap">Bamboo</span>") weekly into "<i>Paper-Stock</i>," may appear somewhat -large, it is necessary I should explain that owing to the nature of -the Process, the desired effect being produced by the reiterated -and continuous action of repeated <i>weak</i> Alkaline Baths or Leys, in -a Series of Vessels, such an operation involves the treatment of a -large quantity of "<i>Raw Material</i>," at one time, and cannot either -conveniently or economically be conducted upon a much smaller scale.</p> - -<p>The cost of the "Plant" and Machinery required for such a Factory -would amount to about ***, packed ready for shipment in England, to -which would have to be added the carriage and cost of erection, with -the necessary buildings, which, however, would be of a very simple and -inexpensive character.</p> - -<p>I do not feel myself competent to determine what quantity of Land -would be required for a plantation to supply such a factory, which -would absorb 100 tons dry, say 400 tons green, "Bamboo" stems weekly, -but assuming 40 tons produce to the acre, with only once annual -cropping, 500 acres should be ample. This calculation doubtless would -be influenced by the varying conditions of climate and soil, as also by -the variety of "Bamboo" cultivated.</p> - -<p>It may be expected that I should in these "<span class="smcap">Remarks</span>" <span class="pagenum"><a id="page16"></a>[p.16]</span> -include some reference to the "<i>Variety</i>" of "<span class="smcap">Bamboo</span>" which -could be most economically and profitably cultivated for the supply of -such a Factory, on the scale I propose.</p> - -<p>In respect to this portion of my subject I experience some difficulty, -inasmuch as the <i>Varieties</i> of "Bamboo" are so numerous, and so widely -distributed.</p> - -<p>A Monograph by Colonel (now General) Munro, C.B., published in the -'Transactions of the Linnean Society,' affords the most elaborate and -comprehensive description of the "Bamboo:" in this paper upwards of 170 -species are described.</p> - -<p>The "<i>Bambusa Vulgaris</i>," as its name indeed denotes, appears to be the -most generally distributed, as it is found in both Hemispheres, General -Munro being in considerable doubt as to which it is a native of.</p> - -<p>I quote from his Monograph: "I have seen it collected by Wallich, in -Silhet, by Hooker, in Chittagong (both North-east India), from Ceylon -wild, in the Mauritius cultivated abundantly, in the West Indies -naturalized, and cultivated in several parts of South America, this is -the only thoroughly cosmopolitan species."</p> - -<p>Bambusa "<i>Gigantea</i>," growing to the height of 120 feet and from -25 to 30 inches circumference; B.

and as it is estimated by the best informed authorities that it -will take, even with the greatest care and under the most favourable -conditions, at least fifteen years to reproduce it from seed (a system -not very likely to be pursued in that country,) at no very remote -period this valuable paper-making material appears doomed to extinction.</p> - -<p>During the last few years a large and increasing supply of -"<span class="smcap">Esparto</span>," or as it is there called "<i>Alfa</i>," has been -received from Africa; and although the quality of African Esparto is -not valued by the paper-trade as high as the Spanish, still it meets -with a ready sale, being used to mix with, or in substitution of the -latter.</p> - -<p>As much as 60,000 tons were imported last year (1874) from Algeria, -and great inducements by concessions and otherwise, are offered by the -French Government to induce railway communication with the interior -districts of that country, where the plant is said to abound on some -of the mountainous plateaux, and thus for some little time the market -may be supplied, but the difficulty of procuring labour, and the -cost of railway carriage for such long distances, will <span class="pagenum"><a id="page21"></a>[p.21]</span> add -considerably to the present charges of transit to this country.</p> - -<p>Within the last two or three years, the Belgian and American -Paper-makers have commenced using "Esparto," and so latterly have the -French, and as our main sources of supply will now be Algeria, (a -French colony,) any material reduction in prices can hardly be looked -for.</p> - -<p>"<span class="smcap">Esparto</span>," like other commercial products, is amenable to -the law of supply and demand;

thus "the comparative expense of chemically reducing <i>Raw -Fibres</i>" is no longer an obstacle to progress.</p> - -<p>The manufacturer of the present day will, in fact, undertake to make -paper from any raw fibre, or fibrous substance that may be submitted to -him.</p> - -<p>He has, however, several questions to consider before he will commit -himself to purchase or contract for any new fibrous material, these -being: its cost, not merely as a raw material, but in the details -of manufacture, and the quality of the paper that can economically -be made from such fibre, either alone, or introducing it as a blend -with the material he at present employs; then, assuming these points -satisfactorily determined, he would desire to know the quantity of such -material annually available, with some guarantee for continuous and -reliable supply at a price not liable to erratic fluctuations.</p> - -<p>The value of "<span class="smcap">Esparto</span>" as a Paper-making material having -been recognized, and its employment almost universally adopted in the -Trade, naturally led to various attempts to introduce other "<i>new -material</i>," which hitherto, however, have met with only partial -success: the "<span class="smcap">Dwarf Palm</span>," <i>Chamœrops humilis</i>, and -"<span class="smcap">Diss</span>," <span class="pagenum"><a id="page24"></a>[p.24]</span> as well as some other materials from North -Africa, have been tried and abandoned as unsuitable: "<span class="smcap">Jute</span>" -also has latterly attracted considerable attention; "Butts" or -"Cuttings," as they are termed, the refuse from the preparation of -the long clean fibre now so largely used as a Textile, have entered -extensively into consumption, being imported from India specially for -paper-makers' use, packed in hydraulic-pressed bales; but this fibre -is difficult and costly to bleach perfectly, and is only employed -for the lower class of "News" and "Common printing," or unbleached, -for "Brown" and "Wrapping" papers; but as it has long been familiar -to the trade in the form of Waste, Gunny-bagging, and Rope, it can -hardly be termed a "<i>New Material</i>."</p> - -<p>Two or three other excellent fibrous materials may be mentioned, -small parcels of which are occasionally to be met with, that are, or -more correctly speaking would be, much prized by Paper-manufacturers -if obtainable at reasonable rates, such as "<span class="smcap">Adansonia Bark</span>," -"<span class="smcap">New Zealand Flax</span>," "<span class="smcap">Manilla Hemp</span>," "<span class="smcap">Sunn</span>," and other <span class="smcap">Indian, Hemp-like -Fibres</span>, all of which will bleach well and make paper of superior quality; -but unfortunately the quantity available is so small, and the supply so -irregular and uncertain, that they can hardly be relied upon as "<i>Raw -Material</i>."</p> - -<p>"<span class="smcap">Wood</span>," both chemically and mechanically prepared, has been, -and indeed is now, used to a very considerable extent; but the latter, -produced by grinding down "billets" from the tree as cut down, on a -grindstone to a pulp, with water, or without water, to the <span class="pagenum"><a id="page25"></a>[p.25]</span> -condition of flour, contains but little fibre, and that fibre with very -little "felting" property (an essential for a good sheet of paper); -thus it can only be used as a "filler-up" for "cheap News" and common -papers, like "clay" (facetiously called in the trade Devonshire linen), -or any other adulterant which the necessities of the Paper-maker, to -meet the market, (<i>or in other words deficient supply of good and cheap -suitable material</i>) compel him to use.</p> - -<p>"<span class="smcap">Wood</span>," chemically prepared, is costly in production, as it -is only possible to reduce it into <i>Pulp</i>, by boiling under very high -pressure, with strong caustic alkali; several mills established both -in England and Scotland, to carry out this manufacture, have abandoned -it, and such <i>Pulp</i> as is now used in the Trade is derived exclusively -from the countries where the wood is grown. The <i>Pulp</i> thus produced, -although somewhat hard and harsh, if the wood is carefully selected, -and properly prepared, will, blended with other material, produce a -fair quality of paper.</p> - -<p>The use of "<span class="smcap">Straw</span>," from the "<i>Cereals</i>," <span class="smcap">Wheat</span>, -<span class="smcap">Oats</span>, and <span class="smcap">Rye</span>, has of late years greatly extended, -both in this country and throughout the continent of Europe, as well -as in the United States of America, either alone or as an admixture -with rags and other material, for all classes of paper, as these -countries equally with England suffer from a deficient supply of <i>Raw -Material</i>; but in England, owing to the increased consumption for -agricultural and feeding purposes, and influenced also by the scarcity -and high prices lately ruling for "<span class="smcap">Esparto</span>" in many districts, -"<span class="smcap">Straw</span>" <span class="pagenum"><a id="page26"></a>[p.26]</span> has become very difficult to obtain, and -considerable quantities have in consequence been imported from Holland -and Belgium, both raw, and as bleached <i>Pulp</i>.</p> - -<p>I may here mention two other fibrous substances, which have from time -to time attracted considerable attention, viz. "<span class="smcap">Maize Leaves</span>" -and "<span class="smcap">Rice Straw</span>," both of them <i>raw materials</i>, from which -a fair quality of paper is produced in the countries where these -plants are cultivated; but, as in their natural condition after being -harvested they are far too bulky to permit of transport to this -country, they would have to be reduced to a portable form where they -grow, and even then, owing to the small yield of "<i>true fibre</i>," their -economical conversion is somewhat doubtful, unless under favourable -conditions.</p> - -<p>The daily increasing demand for <span class="smcap">Paper</span> being recognized, and -the impending if not immediate scarcity of <i>Raw Material</i> available for -its manufacture, up to the present time, having been shown, to what -quarter must the Trade look for an extended supply?</p> - -<p>This it must be admitted has become an important question for -consideration, it being evident that unless some "<i>New Material</i>" -suitable for the purpose is speedily introduced, the "<span class="smcap">Paper -Trade</span>," one of the most important in the <span class="smcap">United Kingdom</span>, -will be seriously crippled; meanwhile of necessity high prices are -maintained, and as a natural consequence the consumer suffers.</p> - - -<h3><span class="pagenum"><a id="page27"></a>[p.27]</span> <span class="smcap">Fibre-producing Plants—Sources of Supply.</span></h3> - -<p>The high value of land precludes the cultivation of any fibrous material -exclusively for paper-making in England, even if this climate was -suitable for its growth;

this list, indeed, might -be extended almost indefinitely, as may be seen by reference to the -work before alluded to, 'The Fibrous Plants of India,' by Dr. Forbes -Royle, as also to the elaborate Paper on the same subject, read at the -meeting of the Society of Arts, May 9, 1860, by Dr. J. Forbes Watson, -Reporter on the Products of India, Dr. Royle's able successor.</p> - -<p>With some few exceptions (notably "Esparto" and some of the Cereal -straws and grasses), the resulting <span class="pagenum"><a id="page29"></a>[p.29]</span> or ultimate fibres from -vegetable fibrous plants, before they can be utilized either for -Textile purposes, or for the manufacture of Paper, must be freed from -the extraneous substances with which during their growth they are more -or less combined.</p> - -<p>In the case of <i>Endogens</i>, the fibres are imbedded or enveloped in -succulent, fleshy, or pulpy stems, or leaves; and in the case of -<i>Exogens</i>, the fibre is combined with, and attaching to, wood, or woody -matter, such extraneous substances or matters constituting, more or -less, a considerable portion both of the weight and bulk of the plant -even when matured.</p> - - -<h3><span class="smcap">Treatment of Fibre-producing Plants.</span></h3> - -<p>From all, or nearly all, <i>Endogenous</i> plants the fibres are extracted -by hand labour, no machinery having been hitherto invented by which -this operation can be performed in an economical and satisfactory -manner.</p> - -<p>The fleshy stems, or leaves, of this class of plants are crushed and -beaten, macerated in water, scraped and roughly combed, to separate the -fibrous from the vascular, or pulpy portion of the plant; sometimes -the plants are buried in wet sand, or mud, leaving them to soak, or -rot, for many days, then beaten on a stone, scraped, and combed; but by -this system the fibres generally lose colour and strength. The yield of -fibre from this class of <i>Endogens</i> ranges from 6 to 12 per cent., and -it is only where native labour is exceedingly cheap and abundant that -such a laborious and tedious process could be carried on.</p> - -<p>The majority of the fibres from <i>Exogenous</i> plants <span class="pagenum"><a id="page30"></a>[p.30]</span> are also, -in somewhat a similar manner obtained solely by manual labour; the -herbaceous, or woody stems of such plants, being first steeped, or -retted, to induce partial fermentation, and facilitate the separation -of the corticular fibres, from the woody stem.</p> - -<p>When produced in Europe, Flax and Hemp form an exception, being -generally dried before steeping, which process is also more -systematically and regularly conducted, and the subsequent separation -of the ultimate fibres effected by breaking, scutching, and heckling; -these operations being as far as possible carried out mechanically.</p> - -<p>When the cost of cultivation, of carriage, freight to this country, -charges and merchants' profit, are added to the outlay involved -in producing clean fibres by the laborious and tedious processes -described, even with the exceedingly cheap labour of <i>tropical -countries</i>, it will readily be understood that they cannot be sold at a -cheap rate.</p> - -<p>When the above outlay has been incurred, and clean merchantable fibre -results, such fibre will generally secure a high price in the market -for Spinning, Roping, and other Textile purposes, far beyond the -Paper-maker's limits, who therefore can only avail himself of damaged -parcels, or such as, being of low or inferior quality, have been -rejected by the "Spinner," and, even then, has to come into competition -with the maker of low-class goods, the common "sacking and mat-maker," -as any fibre of fair strength, long enough to spin into a coarse yarn, -commands good value in the market.</p> - -<p><span class="pagenum"><a id="page31"></a>[p.31]</span> It will be obvious from the preceding remarks that the -Paper-manufacturer, for an extended supply of <i>Material</i>, must look -to a <i>fibre</i> or fibrous substance which, either like "Esparto," can -be utilized direct, without having to pass through this process of -semi-manufacture, or to some other "<i>New Material</i>," which, from the -peculiarity either of its production or growth, and to the simplicity -and economy of its treatment, can be imported into this country, in a -condition suitable for his requirements.</p> - -<p>Knowing from personal observation the peculiarities of the growth, -production, and collection of the "<span class="smcap">Esparto</span>" plant, and believing -the time would come when the supply would be unequal to the demand -(although I must admit, owing to the rapid extension of the Paper-trade, -that time has arrived sooner than I anticipated), I have long and -continuously kept my attention directed to any "<i>New Material</i>" which -appeared likely to become available for Paper-making purposes.</p> - -<p>For many years past, I have devoted much time to the investigation of -<i>Fibres</i>, during which period I have, I believe, tested both chemically -and practically as a Paper-maker, nearly every <i>fibrous material</i> -introduced into the market, with, as may naturally be supposed, -extremely variable results.</p> - -<p>Before any "<i>New Material</i>" will be favourably received by the -Paper-manufacturer, it is clear that certain conditions must be -fulfilled; these being that such "<i>Material</i>" shall favourably compare, -so far as regards quality and cost, with those he now employs, <span class="pagenum"><a id="page32"></a>[p.32]</span> -and that he shall feel satisfied he may rely upon a continuity of -supply, not subject to violent fluctuations in price.</p> - -<p>Once assured on these points, there can be no doubt that, especially -under existing circumstances (viz. deficient supply and high prices), -the Paper-trade would gladly welcome the advent of any "<i>New Material</i>" -calculated to relieve the present, or apprehended scarcity.</p> - - -<h3>NEW MATERIALS.</h3> - -<p>Fortunately for the Paper-trade, and its supply of materials in the -future, two <i>raw fibrous substances</i> exist, to which I now desire -to direct special attention, as I believe it would be difficult, if -not impossible, to meet with any others to compare with them in the -essential points, of reliable supply at extremely low cost combined -with quality.</p> - -<p>With this conviction I have devoted much attention to perfecting a -simple and economical system of treating them, in order to produce a -fibrous "<i>Paper-Stock</i>," considering <i>that</i> to be the most practicable -and best form in which they can be introduced into the Market.</p> - -<p>One of these materials, "<span class="smcap">Megasse</span>," or "<span class="smcap">Begasse</span>," -fulfils the main conditions which would be looked for by the -Paper-manufacturer, inasmuch as vast quantities are available at a -low cost, and owing to the peculiarity of its production being the -necessary <span class="pagenum"><a id="page33"></a>[p.33]</span> by-product of a large and widely spread staple -industry—Sugar—not subject to the ordinary irregularity of supply.</p> - -<p>"<span class="smcap">Megasse</span>," the fibrous residue of the Sugar-Cane (after it -has been crushed to extract the juice), properly prepared, affords -a strong, nervous fibre, or "<i>Fibrous Stock</i>," which bleaches well, -and possesses all the characteristics of a first-class Paper-making -material.</p> - -<p>"<span class="smcap">Megasse</span>" however, as it comes from the crushing rolls, -and even when dried after crushing, is so exceedingly bulky, that -(being produced almost exclusively in tropical countries) the cost of -carriage added to its great liability to damage from fermentation, -precludes the possibility of its being imported to England in its -crude state; moreover, the true fibrous portion of "Megasse" does not -amount to more than 40 per cent., the remainder being constituted of -<span class="smcap">Cellulose</span>, combined with glutenous and other compounds, which -of themselves are useless for Paper-making, and which consequently must -be separated from the residuary or ultimate fibre.</p> - -<p>It follows, therefore, that "<span class="smcap">Megasse</span>" must be converted into -a <i>Fibrous Stock</i> at, or near, the Sugar factory where it is produced, -then dried, and put up in hydraulic-pressed bales for economical -transport.</p> - -<p>The present value of "<span class="smcap">Megasse</span>" (in its crude condition as -produced) is relatively to that of fuel, as, unless it is returned to -the soil as manure (which is the practice in some countries), it is -employed in the Sugar factories, for raising steam, for motive power, -and for evaporating the Cane juice.</p> - -<p><span class="pagenum"><a id="page34"></a>[p.34]</span> As the value of "Megasse" thus considered is very low, -factories established in connection with existing sugar mills for the -manufacture of "<i>Paper-Stock</i>," where sufficient quantities of so bulky -a material could be concentrated, and where other favourable conditions -exist (of which an abundant supply of water is an essential), would -yield a large profit to the planter or sugar manufacturer, as the -"<i>Paper-Stock</i>" he would produce would meet with a ready sale at -prices at least equivalent to "<span class="smcap">Esparto</span>," reduced to the same -condition.</p> - -<p>Having made "<i>Paper-Stock</i>," and "<i>Paper</i>" of good quality from -"<span class="smcap">Megasse</span>," and determined the profitable result of such a -manufacture beyond dispute, I look forward at no very distant date to -see the Paper-trade of this country receiving, at least, a portion of -its <i>raw material</i> from some of our own <i>Colonies</i> and <i>Dependencies</i> -(in most of which Sugar is produced), instead of, as now, being -entirely dependent on Foreign Countries for supply.</p> - -<p>It is estimated that the consumption of sugar in England amounts -annually to upwards of 800,000 tons, or about 57 lb. per head of the -population; and as it may be assumed that for each ton of sugar 1 ton -of "Megasse" at least is produced, it will be seen that a large reserve -of <i>Fibrous Material</i> is available, awaiting the enterprise of either -the Sugar or the Paper-manufacturer or a combination of both.</p> - -<p>It is now my object to show to the <i>Two parties</i> mainly interested, the -<span class="smcap">Producer</span> and the <span class="smcap">Consumer</span>, how closely their interests are coincident, -and how <span class="pagenum"><a id="page35"></a>[p.35]</span> both would be benefited by the creation and development -of a new <span class="smcap">Industry</span>.</p> - -<p>The <span class="smcap">Producer</span>, the Sugar-manufacturer, is, in point of fact -suffering from a similar competition to that experienced by the -Paper-manufacturer in 1861—handicapped by the <i>drawback</i> allowed on -the export of <span class="smcap">French, and Belgian, Beet-root Sugar</span>, with which -he is unable to compete, in the same manner as the Paper-maker suffered -from the introduction of <span class="smcap">French, and Belgian, Paper</span>—<i>free</i>, -while the <span class="smcap">Raw Material</span>—<span class="smcap">Rags</span>, paid a heavy <i>export duty</i>.</p> - -<p>The <span class="smcap">Consumer</span>, the Paper-manufacturer, is suffering from a lack -of suitable material, which the Producer is able to supply, and by so -supplying and utilizing a by-product, hitherto of little value to him, -places himself in a position to meet his competitors on equal, if not -better terms in the market.</p> - -<p>It is true, that this (to him) new system of utilizing what may now be -termed a waste, or by-product, would involve the outlay of additional -capital, by the Sugar-planter or manufacturer, which he may deem -foreign to his present business, but manufacturers now-a-days make -their profits mainly by utilizing by-products.</p> - -<p>A familiar instance of this may be cited in the Chemical trade; the -muriatic acid produced in the manufacture of soda, formerly run to -waste, being now employed for making bleaching powder; and, still more -recently, the by-products annaline, anthracene, ammonia, &c., which -formerly created a nuisance wherever Gas-Works existed, now constitute -a large portion of their profits.</p> - -<p><span class="pagenum"><a id="page36"></a>[p.36]</span> "<span class="smcap">Bamboo</span>," the other <i>Raw Material</i> to which I have -alluded, can hardly be called "<i>New</i>," it being well known that both -the Chinese and Japanese have from time immemorial employed "Bamboo" -for Paper-making purposes; and I have shown in the preceding "Remarks" -that attempts have more recently been made, not hitherto affording -successful commercial results.</p> - -<p>It therefore would have been more correct had I, in directing attention -to "<span class="smcap">Bamboo</span>," described it as an "<i>Old material</i>" under "<i>New -treatment</i>." Such indeed was the case with "<span class="smcap">Esparto</span>," an "<i>Old -material</i>," well known, and tried ineffectually by many, previous to -my process for converting it into paper being adopted, which, however, -did not take place until it had been fully tested and approved, leading -then to its speedy employment.</p> - -<p>I believe with my new system of treatment "<span class="smcap">Bamboo</span>" will prove -to be as superior to "Esparto," in every respect as "Esparto" was found -to be superior to "Straw," the only other "<i>raw material</i>" used when it -was introduced.</p> - -<p>"<span class="smcap">Bamboo</span>" differs from "<span class="smcap">Megasse</span>," inasmuch as the -latter is produced, as it were, involuntarily, its maximum value as a -"<i>raw product</i>" being determined by its comparison with fuel; whereas -"<span class="smcap">Bamboo</span>" would have to be cultivated; but, as this plant -will not only grow, but flourish, in localities unsuitable for other -cultivation, and is produced with such extraordinary rapidity and -abundance, it would appear that, as a <i>Raw Product</i>, it would not cost -much, if any, more than "<span class="smcap">Megasse</span>."</p> - -<p><span class="pagenum"><a id="page37"></a>[p.37]</span> It is hardly my province to discuss here to which of the two -materials, "<span class="smcap">Megasse</span>" or "<span class="smcap">Bamboo</span>," the preference should -be given. Suffice it to say that, with "<i>the admitted fact</i>" of the -increasing scarcity of <i>Raw Material</i> for Paper-making, there is ample -scope for both. I have only to add that I shall be happy to advise with -parties who may desire to interest themselves in either question.</p> - - -<h3>CONCLUSION.</h3> - -<p>As I have broadly stated that "<i>Paper-Stock</i>" can be produced from both -"<span class="smcap">Bamboo</span>" and "<span class="smcap">Megasse</span>," to show a good <i>Profit</i>, it -may be well to mention the present cost of "<span class="smcap">Esparto</span>" reduced to -the same condition (of "<i>Paper-Stock</i>"), as it is with this <i>Material</i> -these <i>Fibres</i> would mainly have to compete, seeing that with its large -consumption and widely extended use for most classes of Paper it now rules -the Market.</p> - -<p>The cost of good <i>Spanish</i> "<span class="smcap">Esparto</span>" at current rates, is, -delivered into a Mill (say), 10<i>l.</i> per ton; it is generally assumed in -the Paper-trade that about 2 tons of "Esparto" are required to make 1 -ton paper, the yield being from 48 to 50 per cent.</p> - -<p>At 50 per cent. yield therefore we have 20<i>l.</i> per ton for "<i>Raw -Material</i>." Add to this, for chemicals, boiling, fuel, and labour, -50<i>s.</i> × 2 tons, we arrive at 25<i>l.</i> for the cost of "Esparto" in the -same condition of <i>unbleached</i> "<i>Stock</i>," sufficient for 1 ton paper.</p> - -<p>"<span class="smcap">Alfa</span>" or "<i>African</i>" Esparto does not afford so <span class="pagenum"><a id="page38"></a>[p.38]</span> good -a yield, neither will it bleach to so high a colour, nor make so good a -quality of paper as "<i>Spanish</i>"; its value therefore is proportionately -lower in the Market, say 8<i>l.</i> per ton as compared with 10<i>l.</i>: the -cost therefore of "Alfa" reduced to a similar condition of "<i>Stock</i>" -may be taken at 21<i>l.</i></p> - -<p>"<span class="smcap">Alfa</span>" (if carefully selected) so closely resembles -"<i>Spanish</i>" "<span class="smcap">Esparto</span>," in its <i>raw condition</i>, that it -is very difficult to distinguish one from the other, and when the -two are skilfully blended, it is impossible to do so, until the -bleaching process of manufacture is reached; thus, it has happened, -that during the past two or three years many thousands of tons of -"<span class="smcap">Alfa</span>," having taken a "tour" through "<i>Spain</i>," and being -there naturalized, have found their way to England and been sold to the -unsophisticated English Paper-maker as "<i>Spanish</i>" "<span class="smcap">Esparto</span>," -thus supplementing the rapid exhaustion of the indigenous grass of that -country.</p> - -<p>"<span class="smcap">Wood</span>" "<i>Pulp</i>" as I have mentioned, is imported, both -mechanically and chemically prepared, the latter (unbleached) finding -a ready sale, at 24<i>l.</i> to 25<i>l.</i> per ton; "<span class="smcap">Straw</span>" "<i>Pulp</i>" -also (bleached) realizes 26<i>l.</i> to 27<i>l.</i> per ton, but neither of these -materials are likely to be introduced to any considerable extent.</p> - -<p>"<i>Paper-Stock</i>," resulting from either "<span class="smcap">Bamboo</span>" or -"<span class="smcap">Megasse</span>," will show a very large margin of profit from the -figures I have quoted, thus allowing for any necessary reduction should -prices fall from increased supplies.</p> - -<p>In concluding my "<i>Remarks</i>," having in the preceding <span class="pagenum"><a id="page39"></a>[p.39]</span> Pages -suggested the conversion of "<i>Raw Fibrous Substances</i>," notably, -"<span class="smcap">Bamboo</span>" and "<span class="smcap">Megasse</span>," into Fibrous "<i>Paper-Stock</i>," -I ought perhaps distinctly to explain the difference between -"<i>Half-Stuff</i>," or "<i>Pulp</i>," and "<i>Paper-Stock</i>," and my reasons -for expressing a preference for the latter form of preparation,—a -preference warranted, I believe, both by practical, and economical -considerations.</p> - -<p>Whatever "<i>Material</i>" the Paper-maker employs, be it Rags (of any -denomination) or any other "<i>Fibre</i>," or "<i>Fibrous</i>," substance, after -Boiling, he disintegrates, or comminutes it into "<i>Half-Stuff</i>," -before, or while bleaching. This process, carried a stage farther, -converts the "<i>Half-Stuff</i>" into "<i>Pulp</i>." Herein, not less than in -the proper selection of his "<i>Raw Material</i>," lies the skill of the -Paper-maker, as, however good his "<i>Material</i>" may be, in its <i>Raw</i> -or normal condition, it may be very easily spoilt in either of the -processes of Boiling,—Bleaching,—or Pulping.</p> - -<p>For example, when Bread is once toasted, thereby becoming brown (and -the purer and whiter the greater the change), whereby its chemical and -mechanical character has become altered, no power can reconvert it into -its original condition; in like manner, however good a "<i>Raw Fibrous -Material</i>" may be, if that "<i>Material</i>" be either over-boiled, or -over-pulped, no power will restore its normal character.</p> - -<p>Moreover, a "<i>Fibrous</i>" substance once reduced to the condition of -"<i>Pulp</i>," it is difficult, if not impossible, even for a Microscopist, -to distinguish accurately <span class="pagenum"><a id="page40"></a>[p.40]</span> the character or quality of the -original "<i>Fibre</i>,"—its strength,—or whether it has been properly -or improperly treated, and reduced to that condition—until, perhaps -too late, when he has bleached it, and converted it, or attempted to -convert it, into a sheet of Paper.</p> - -<p>With a Fibrous "<i>Paper-Stock</i>," however, these objections do not apply, -or certainly not to the same degree, as the Paper-maker could readily -examine and judge of the character and strength of the "<i>Fibre</i>" -whether it was clean and free from imperfections or adulterations—in -fact, could see what he was buying, or proposing to buy, which he could -not do with "<i>Half-Stuff</i>" or "<i>Pulp</i>."</p> - -<p>So far as the Producer is concerned, his outlay for the primary "Plant" -and the mechanical appliances, the cost of the subsequent treatment, -the drying, packing, and economical carriage and freight from a Foreign -country, would in all respects be less for "<i>Paper-Stock</i>" than for -"<i>Half-Stuff</i>" or "<i>Pulp</i>."</p> - -<p>Speaking from the experience of some years, during which I have conducted -the manufacture and sale of many thousand tons of "<i>Half-Stuff</i>" prepared -from "<span class="smcap">Esparto</span>" and other "<i>Raw Fibres</i>," I feel satisfied that -in introducing a <i>New Semi-prepared Material</i>, from a Foreign country, -the preference would be given by the practical Paper-maker to a "<i>Fibrous -Paper-Stock</i>."</p> - -<p class="ralign2"><span class="smcap">Thomas Routledge.</span></p> -<p> </p> -<p class="ralign3 ftsize85"><span class="smcap">Claxheugh, Sunderland</span>,</p> -<p class="ftsize50"> </p> -<p class="ralign4 ftsize75">1875.</p> - - - - -<h2>FOOTNOTES:</h2> - - -<div class="footnote indent03"> -<p><a name="Footnote_A" id="Footnote_A"></a><a href="#FNanchor_A"><span class="label">A</span></a> The Journal of the Society of Arts, 28th Nov., 1856, was printed -on paper made from Esparto, at Eynsham Mills, near Oxford, then in my -occupation.</p> -</div> - - - - -<div class="box martop4"> -<h2>Transcriber's Notes:</h2> - - -<p>On page <a href="#page15">15</a> some text is missing it is marked as ***.</p> - -<p>Other than the corrections listed below, printer's inconsistencies in -spelling, punctuation, hyphenation, and ligature usage have been retained.</p> - -<p>The following misprints have been corrected:</p> - -<ul class="tn"> - <li>changed<br/> <span class="ftsize105">"with "</span><span class="smcap">Hemp</span><span class="ftsize105">' and "</span><span class="smcap">Flax</span><span class="ftsize105">," where"</span><br/> into<br/> <span class="ftsize105">"with - "</span><span class="smcap">Hemp</span><span class="ftsize105">" and "</span><span class="smcap">Flax</span><span class="ftsize105">," where"</span> (page <a href="#page8">8</a>)</li> - - <li>changed<br/> <span class="ftsize105">"the "15,000 <i>tons</i> of Rags estimated by"</span><br/> into<br/> <span class="ftsize105">"the "15,000 - <i>tons</i> of Rags" estimated by"</span> (page <a href="#page22">22</a>)</li> -</ul> -</div> - - - - - - - -<pre> - - - - - -End of the Project Gutenberg EBook of Bamboo, Considered as a Paper-making -Material, by Thomas Routledge - -*** END OF THIS PROJECT GUTENBERG EBOOK BAMBOO *** - -***** This file should be named 54090-h.htm or 54090-h.zip ***** -This and all associated files of various formats will be found in: - http://www.gutenberg.org/5/4/0/9/54090/ - -Produced by Iris Schröder-Gehring, Chris Curnow and the -Online Distributed Proofreading Team at http://www.pgdp.net -(This file was produced from images generously made -available by The Internet Archive) - - -Updated editions will replace the previous one--the old editions -will be renamed. - -Creating the works from public domain print editions means that no -one owns a United States copyright in these works, so the Foundation -(and you!) can copy and distribute it in the United States without -permission and without paying copyright royalties.

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.
