Rh the case of a mine of precious stones. These are to some small extent employed in the productive arts, as diamonds by the glass-cutter, emery and corundum for polishing, but their principal destination, that of ornament, is a direct use; though they commonly require, before being so used, some process of manufacture, which may perhaps warrant our regarding them as materials. Metallic ores of all sorts are materials merely.

Under the head, production of materials, we must include the industry of the wood-cutter, when employed in cutting and preparing timber for building, or wood for the purposes of the carpenter's or any other art. In the forests of America, Norway, Germany, the Pyrenees and Alps, this sort of labour is largely employed on trees of spontaneous growth. In other cases, we must add to the labour of the wood-cutter that of the planter and cultivator.

Under the same head are also comprised the labours of the agriculturist in growing flax, hemp, cotton, feeding silkworms, raising food for cattle, producing bark, dye-stuffs, some oleaginous plants, and many other things only useful because required in other departments of industry. So, too, the labour of the hunter, as far as his object is furs or feathers; of the shepherd and the cattle-breeder, in respect of wool, hides, horn, bristles, horse-hair, and the like. The things used as materials in some process or other of manufacture are of a most miscellaneous character, drawn from almost every quarter of the animal, vegetable, and mineral kingdoms. And besides this, the finished products of many branches of industry are the materials of others. The thread produced by the spinner is applied to hardly any use except as material for the weaver. Even the product of the loom is chiefly used as material for the fabricators of articles of dress or furniture, or of further instruments of productive industry, as in the case of the sailmaker. The currier and tanner find their whole occupation in converting raw material into what may be termed prepared material. In strictness of speech,
