The fibers used in the manufacture of cloth are of two different natures, vegetable and animal.

The vegetable fibers may be divided into three distinct classes:

1. The cotton having soft, lint-like fibers, one-half to two inches in length, is obtained from the seed-pods, called "bolls."

2. The fibers from flax, hemp and jute are flexible and of soft texture, ten to one hundred inches in length.

3. The hard or leaf fibers, including manila, sisal, istle and the New Zealand fibers, all having rather stiff" woody fibers, one to ten feet long, are obtained from the leaf or the leaf stem.

The animal fibers are obtained from the wool bearing animals such as common sheep, Angora and Cashmere goats and the hair of the camel.

The silk fiber is obtained from the cocoon of a caterpillar.
