converted into thread in a considerably shorter space of time than in
the ancient mode; leaving to man merely to feed the machine, and join
the threads when they break. The sheep, whose wool forms the material
for nearly all woollen clothing, came originally from Africa.


Does weaving differ according to the material used?

The principle of weaving is the same in every kind of fabric, and

Is not the employment of Wool in the manufacture of Clothing of great
antiquity?

In the earliest records we possess of the arts of mankind, wool is
mentioned as forming a chief article in the manufacture of clothing;
it is spoken of in the Bible, as a common material for cloth, as early
