СКАЧАТЬ culture is already a flourishing industry in the Sisal hemp region. A pineapple plant matures but one apple in a season, and after the harvest of fruit the old leaves are of no further use to the plant, and may be removed. The leaves have the same structural system as the agaves – that is, they are composed of a cellular mass through which the fibers extend, and when the epidermis and pulpy matter are eliminated the residue is a soft, silklike filament, the value of which has long been recognized. Only fifty pounds of this fiber can be obtained from a ton of leaves, but, as the product would doubtless command double the price of Sisal hemp, its production would be profitable. How to secure this fiber cheaply is the problem. The Sisal hemp machines are too rough in action for so fine a fiber, and, at the rate of ten leaves to the pound, working up a ton of the material would mean the handling of over twenty thousand leaves to secure perhaps three dollars' worth of the commercial product. Were the fiber utilized in the arts, however, and its place established, it would compete in a measure with flax as a spinning fiber, for its filaments are divisible to the ten-thousandth of an inch. The substance has already been utilized to a slight extent in Eastern countries (being hand-prepared) in the manufacture of costly, filmy, cobweblike fabrics that will almost float in air.

      Another possible fiber industry for Florida is the cultivation of bowstring hemp, or the fiber of a species of Sansevieria that grows in rank luxuriance throughout the subtropical region of the State. The fiber is finer and softer than Sisal hemp, though not so fine as pineapple fiber, and would command in price a figure between the two. The yield is about sixty pounds to the ton of leaves. Many other textile plants might be named that have been experimented with by the Government or through private enterprise, but the most important, in a commercial sense, have been named.

      A Plant of New Zealand Flax.

      There is a considerable list of plants, however, which are the subject of frequent inquiry, but which will never be utilized commercially as long as other more useful fibers hold the market. These for the most part produce bast fiber, and the farmer knows them as wild field growths or weeds. They are interesting in themselves, and many of them produce a fair quality of fiber, but to what extent they might be brought into cultivation, or how economically the raw material might be prepared, are questions the details of which only experiment can determine. But the fact that at best they can only be regarded as the substitutes for better, already established, commercial fibers has prevented serious experiment to ascertain their place. They are continually brought to notice, however, for again and again the thrifty farmer, as he finds their bleached and weather-beaten filaments clinging to the dead stalks in the fields, deludes himself in believing that he has made a discovery which may lead to untold wealth, and a letter and the specimen are promptly dispatched to the fiber expert for information concerning them. In such cases all that can be done is to give full information, taking care to let the inquirer down as easily as possible.

      The limit of practical work in the direction of new textile industries is so clearly defined that the expert need never be in doubt regarding the economic value of any fiber plant that may be submitted to him for an opinion, and the long catalogue of mere fibrous substances will never demand his serious attention.

      In studying the problem of the establishment of new fiber industries, therefore, we should consider "materials" rather than particular species of plants – utility or adaptation rather than acclimatization. We should study the entire range of textile manufacture, and before giving attention to questions of cultivation we should first ascertain how far the plants which we already know can be produced within our own borders may be depended upon to supply the "material" adapted to present demands in manufacture. If the larger part of our better fabrics – cordage and fine twines, bagging, and similar rough goods – can be made from cotton, flax, common hemp, and Sisal hemp, which we ought to be able to produce in quantity at home, there is no further need of costly experiments with other fibers. Unfortunately, however, it is possible for manufacturers to "discriminate" against a particular fiber when the use of another fiber better subserves their private interests. As an example, common hemp was discriminated against in a certain form of small cordage, in extensive use, because by employing other, imported fibers, it has been possible in the past to control the supply, and in this day of trusts such control is an important factor in regulating the profits. With common hemp grown on a thousand American farms in 1890, the price of Sisal and Manila hemp binding twine, of which fifty thousand tons were used, would never have been forced up to sixteen and twenty cents a pound, when common hemp, which is just as good for the purpose, could have been produced in unlimited quantity for three and a half cents. The bagging with which the cotton crop is baled is made of imported jute, but common hemp or even low-grade flax would make better bagging. A change from jute to hemp or flax in the manufacture of bagging (it would only be a return to these fibers), could it be brought about, would mean an advantage of at least three million dollars to our farmers. Yet in considering such a desirable change we are confronted with two questions: Is it possible to compete with foreign jute? and can prejudice be overcome? For it is true that there are, even among farmers, those who would hesitate to buy hemp bagging at the same price as jute bagging because it was not the thing they were familiar with. But some of them will buy inferior jute twine, colored to resemble hemp, at the price of hemp, and never question the fraud.

      Cabbage Palmetto in Florida.

      Our farmers waste the fibrous straw produced on the million acres of flax grown for seed. It has little value, it is true, for the production of good spinning flax, yet by modifying present methods of culture, salable fiber can be produced and the seed saved as well, giving two paying crops from the same harvest where now the flaxseed grower secures but one.

      In summarizing the situation in this country, therefore, it will be seen that, out of the hundreds of fibrous plants known to the botanist and to the fiber expert, the textile economist need only consider four or five species and their varieties, all of them supplying well-known commercial products that are regularly quoted in the world's market price current, the cultivation and preparation of which are known quantities. Were the future of new fiber industries in this country to rest upon this simple statement, there would be little need of further effort. The problem, however, is one of economical adaptation to conditions not widely understood in the first place, and not altogether within control in the second.

      Twenty flax farmers in a community decide to grow flax for fiber, and two of these farmers are perhaps acquainted with the culture. They go to work each in his own way; ten make a positive failure in cultivation for lack of proper direction, five of the remaining ten fail in retting the straw, and five succeed in turning out as many different grades of flax line, only one grade of which may come up to the standard required by the spinners. And all of them will have lost money. If the failure is investigated it will be discovered that the proper seed was not used; in some instances the soil was not adapted to the culture, and old-fashioned ideas prevailed in the practice followed. The straw was not pulled at the proper time, and it was improperly retted. The breaking and scutching were accomplished in a primitive way, because the farmers could not afford to purchase the necessary machinery, and of course they all lost money, and decided in future to let flax alone.

      But the next year the president of the local bank, the secretary of the town board of trade, and three or four prosperous merchants formed a little company and built a flax mill. A competent superintendent – perhaps an old country flax-man – was employed, a quantity of good seed was imported, and the company contracted with these twenty farmers to grow five, ten, or fifteen acres of flax straw each, under the direction of the old Scotch superintendent. The seed was sold to them to be paid for in product; they were advised regarding proper soil and the best practice to follow; they grew good straw, and when it was ready to harvest the company took it off their hands at a stipulated price per ton. The superintendent of the mill assumed all further responsibility, attended to the retting, and worked up the product. Result: several carloads of salable flax fiber shipped to the Eastern market in the winter, the twenty farmers had "money СКАЧАТЬ
