Cotton is not only cheaper than linen (which is woven from flax), but has several advantages over it: it takes dyes much better, and produces brighter colors; the improvements made in the machinery for spinning and weaving cotton, have not only enabled us to match the spinners and weavers of India, which, for a long time supplied nearly the whole of Europe, but at the present time, cotton cloths of English manufacture are exported to India for the purpose of clothing the natives of that country. FLAX. Illustration: FLAX (‡ PLANT). Flax is obtained from the stalks of the flax plant _Linum Usitatissimum_, it is supposed to have been originally brought from Egypt, where linens have been woven from its fibres from time immemorial. It is now found growing wild in this country, and is cultivated in most parts of Europe, either for its stalks to make flax, or for its seed (linseed), which is used for fattening cattle, and yields an oil (linseed oil) much used in the making of paint. The plant grows to two or three feet in height, bears a blue flower in July, and has a great hollow stem; when gathered, it is pulled up by the roots. The fibres of flax are very long and even; it is the inner part which yields the best fibres. SILK. Illustration: SILK (‡ WORMS). Silk is by far the strongest of the textile fabrics, being nearly three times as strong as flax; it consists of the filaments spun by the silk-worm, _Phalœna Bombyx Anori_. These filaments are always double, proceeding from two holes in the head of the worm, and are united by a sort of varnish which is moist and clammy when the threads proceed from the insect, and causes them to adhere together. The silk-worm in spinning, moves the head backwards and forwards, attaching the threads on alternate sides and all around till it is completely covered in with a ball of silk; in this state it is called a “coccoon.” The silk-worm, like others of its class, undergoes four changes or metamorphoses--the Egg, the Grub or Worm, the Chrysalis, and the Imago or perfect insect, which, in this case, is a moth. The worm spins the coccoon to defend itself from injury and cold, but man, taking advantage of the useful qualities possessed by these fine filaments, spins them into his most gorgeous apparel. The coccoons are unwound by placing them in a basin of warm water, which dissolves the varnish, and they are then slowly wound off; formerly this was done by hand, but now machinery is chiefly employed which winds off the silk from a bowl full of coccoons at the same time. The silk is coiled into hanks or skeins, and in this form is imported into this country; from these hanks it is wound off on to large six-sided wheels called “swifts,” and from these on to bobbins or reels; it is then wound off from two or three of these bobbins on to one other bobbin, the threads of silk being laid side by side, and in this
