The Jute Industry: from Seed to Finished Cloth | Page 3

soon became apparent, for in the first place it was difficult to induce the natives to remain inside the works during the period of training, and equally difficult to keep the trained operatives constantly employed. Monetary affairs induced them to leave the mills and factories for their more usual mode of living in the country.
In the face of these difficulties, however, the industry grew in India as well as in Dundee. For several years before the war, the quantity of raw jute fibre brought to Dundee and other British ports amounted to 200,000 tons. During the same period preceding the war, nearly 1,000,000 tons were exported to various countries, while the Indian annual consumption--due jointly to the home industry and the mills in the vicinity of Calcutta--reached the same huge total of one million tons.
The growth of the jute industry in several parts of the world, and consequently its gradually increasing importance in regard to the production of yarns and cloth for various purposes, enables it to be ranked as one of the important industries in the textile group, and one which may perhaps attain a much more important position in the near future amongst our national manufacturing processes. As a matter of fact, at the present time, huge extensions are contemplated and actually taking place in India.
CHAPTER II.
CULTIVATION
Botanical and Physical Features of the Plant. Jute fibre is obtained from two varieties of plants which appear to differ only in the shape of the fruit or seed vessel. Thus, the fruit of the variety Corchorus Capsularis is enclosed in a capsule of approximately circular section, whereas the fruit of the variety Corchorus Olitorius is contained in a pod. Both belong to the order Tiliacea, and are annuals cultivated mostly in Bengal and Assam.
Other varieties are recorded, e.g. the Corchorus Japonicus of Japan, and the Corchorus Mompoxensis used in Panama for making a kind of tea, while one variety of jute plant is referred to in the book of job as the Jew's Mallow; this variety C. Olitorius, has been used in the East from time immemorial as a pot herb.
The two main varieties C. Capsularis and C. Olilorius are cultivated in Bengal for the production of fibre, while for seed purposes, large tracts of land are cultivated in Assam, and the seeds exported for use principally in Mymensingh and Dacca.
The above two varieties of the jute plant vary in height from 5 to 15 feet, and, in a normal season, reach maturity in about four months from the time of sowing. In some districts the stems of jute plants are sometimes rather dark in colour, but, in general, they are green or pink, and straight with a tendency to branch. The leaves are alternate on the stems, 4 to 5 inches in length, and about 1-1/2 inches in breadth with serrated edges. Pale yellow flowers spring from the axil (axilla) of the leaves, and there is an abundance of small seeds in the fruit which, as mentioned, is characteristic of the variety.
While many attempts have been made to cultivate jute plants in various parts of the world, the results seem to indicate that the necessary conditions for the successful cultivation of them are completely fulfilled only in the Bengal area, and the geographical position of this province is mainly responsible for these conditions. On referring to a map of India, it will be seen that Bengal is directly north of the bay of that name, and is bounded on the north by the great Himalayan mountains.
During the winter period when the prevailing winds are from the north, large areas of the mountainous regions are covered with snow, but when the winds change and come from the south, and particularly during the warmer weather, the moist warm air raises the general temperature and also melts much of the snow on the mountain tracts. The rain and melted snow swell the two great rivers on the east and west of Bengal--the Patna and the Brahmaputra--and the tremendous volume of water carries down decayed vegetable and animal matter which is ultimately spread on the flat areas of Bengal as alluvial deposits, and thus provides an ideal layer of soil for the propagation of the jute plants.
The cultivation of land for the growing of jute plants is most extensively conducted in the centres bordering on the courses of the rivers, and particularly in Mymensingh, Dacca, Hooghly and Pabna, and while 90 per cent. of the fibre is produced in Bengal, Orissa and Bihar, there is 10 per cent. produced outside these areas.
The Corchorus Capsularis variety is usually cultivated in the higher and richer soils, while the Corchorus Olitorius variety is most suited for the lower-lying alluvial soils, and to the districts where the rainfall is irregular; indeed, the C. Olitorius may be grown in
