Man is not the only animal who labors; but he is the only one who _improves_ his workmanship. This improvement he effects by _Discoveries_ and _Inventions_. His first important discovery was the fact that he was naked; and his first invention was the fig-leaf apron. This simple article, the apron, made of leaves, seems to have been the origin of _clothing_--the one thing for which nearly half of the toil and care of the human race has ever since been expended. The most important improvement ever made in connection with clothing, was the invention of _spinning_ and _weaving_. The spinning jenny, and power loom, invented in modern times, though great _improvements_, do not, _as inventions_, rank with the ancient arts of spinning and weaving. Spinning and weaving brought into the department of clothing such abundance and variety of material. Wool, the hair of several species of animals, hemp, flax, cotton, silk, and perhaps other articles, were all suited to it, affording garments not only adapted to wet and dry, heat and cold, but also susceptible of high degrees of ornamental finish. Exactly _when_, or _where_, spinning and weaving originated is not known. At the first interview of the Almighty with Adam and Eve, after the fall, He made “coats of skins, and clothed them” (Genesis iii: 21). The Bible makes no other allusion to clothing, _before_ the flood. Soon _after_ the deluge Noah’s two sons covered him with a _garment_; but of what _material_ the garment was made is not mentioned (Genesis ix: 23). Abraham mentions “_thread_” in such connection as to indicate that spinning and weaving were in use in his day (Genesis xiv: 23), and soon after, reference to the art is frequently made. “_Linen breeches_” are mentioned (Exodus xxviii: 42), and it is said “all the women that were wise-hearted did _spin_ with their hands” (Exodus xxxv: 25), and, “all the women whose heart stirred them up in wisdom _spun_ goats’ hair” (Exodus xxxv: 26). The work of the “_weaver_” is mentioned (Exodus xxxv: 35). In the book of Job, a very old book, date not exactly known, the “_weavers’ shuttle_” is mentioned. The above mention of “_thread_” by Abraham is the oldest recorded allusion to spinning and weaving; and _it_ was made about two thousand years after the creation of man, and now, near four thousand years ago. Profane authors think these arts originated in Egypt; and this is not contradicted, or made improbable, by anything in the Bible; for the allusion of Abraham, mentioned, was not made until after he had sojourned in Egypt.
