In one area the men work amongst the water breaking up the woody structure of the retted plants by means of mallets and cross rails fixed to uprights in the water; others break the stems by hand; while in other cases the stems are handed out of the water to women who strip off the fibrous layer and preserve intact the central core or straw to be used ultimately for thatching.  The strips of fibre are all cleaned and rubbed in the water to remove all the vegetable impurities, and finally the fibre is dried, usually by hanging it over poles and protecting it from the direct rays of the sun.

If the water supply is deficient in the vicinity where the plants are grown, it may be advantageous to convey the fibrous layers to some other place provided with a better supply of water for the final washing and drying; imperfect retting and cleaning are apt to create defects in the fibre, and to cause considerable trouble or difficulties in subsequent branches of the industry.

Fig. 3 illustrates photomicrographs of cross sections of a jute plant.  The lower illustration represents approximately one quarter of a complete cross section.  The central part of the stem or pith is lettered A; the next wide ring B is the woody matter; the outer covering or cuticle is marked C; while the actual fibrous layer appears between the parts B and C, and some of the fibres are indicated by D. The arrows show the corresponding parts in the three distinct views.  The middle illustration shows an enlarged view of a small part of the lowest view, while the upper illustration is a further enlarged view of a small section of the middle view.  It will be seen that each group of fibres is surrounded by vegetable matter.

Another method of stripping the fibrous layer off the stems or stalks, and one which is practised in certain districts with the object of preserving the straws, consists in breaking off a small portion, say one foot, at the top end of the stem; the operative then grasps the tops by the hand and shakes the plants to and fro in the water, thus loosening the parts, after which the straws float out, leaving the fibrous layer free.  The straws are collected for future use, while the fibre is cleaned and washed in the usual way.

CHAPTER IV.  ASSORTING AND BALING JUTE FIBRE

The Indian raw jute trade is conducted under various conditions.  The method of marketing may be of such a nature that the farmers in some districts may have to make a rough assortment of the fibre into a number of qualities or grades, and these grades are well known in the particular areas; on the other hand, the farmers may prefer to sell the total yield of fibre at an overhead price per maund.  A maund is approximately equal to 8 lbs., and this quantity forms a comparatively small bundle.  In other cases, the fibre is made up into what is known as a “drum”; this is a hand-packed bale of from 1 1/2 to 3 or 3 1/2 maunds; it is a very convenient size for transit in India.
