composition of other stuffs,
and in working with the needle.
How is the Cotton separated from the seed?
By machines called _cotton gins_, of which there are two kinds; the
_roller-gin_, and the _saw-gin_. In the former, the cotton, just as
gathered from the plant, is drawn between two rollers, placed so
closely together as to permit the passage of the cotton, but not of
the seeds, which are consequently left behind. In the _saw-gin_, the
cotton is placed in a receiver, one side of which consists of a
grating of parallel wires, about an eighth of an inch apart; circular
saws, revolving on a common axis between these wires, entangle in
their teeth the cotton, and draw it from the seeds, which are too
large to pass between the wires.
How is it made into Calico, &c.?
The cotton having been separated from the seed, is spun by a machine
for the purpose. It is next woven, then dressed, and printed.
What is Cloth?
The word, in its general sense, includes all kinds of stuffs woven in
the loom, whether the threads be of wool, cotton, hemp, or flax.
To what is it more particularly applied?
To a web or tissue of woollen threads.
_Web_, any thing woven.
What is Wool?
The covering or hair of sheep. To prepare it for the weaver, it is
first shorn, washed, and dried, then carded or combed by machinery
into fibres or threads: formerly this was always performed by the
hand, by means of an instrument, called a comb, with several rows of
pointed teeth; this, though not much used now, is still occasionally
employed, except in large factories. This combing is repeated two or
three times, till it is sufficiently smooth and even for spinning.
Spinning or converting wool, or cotton, silk, &c. into thread, was
anciently performed by the distaff and spindle: these we find
mentioned in sacred history, and they have been used in all ages, and
in all countries yet discovered. The natives of India, and of some
other parts of the world, still employ this simple invention.
What was the next improvement?
The invention of the hand-wheel. In 1767, a machine called the
spinning-jenny was invented by a weaver named Hargreaves; but the
greatest improvement in the art of spinning was effected by Mr.
Arkwright, in 1768: these two inventions were combined, and again
improved upon in 1776; so that by the new plan, the material can be
converted into thread in a considerably shorter space of time than in
the ancient
