The effect of climate and soil on the composition of the grain has been discussed. Uses of Wheat.—By far the largest proportion of the world's supply of flour is made from wheat.

The semolina is mixed with about 30 per cent, of water, worked into a stiff dough, and given a thorough kneeding. The dough is then forced through a press, from which it issues in long hollow tubes. These tubes of moist dough are then carefully dried in a manner to prevent them from becoming too brittle or sour. Vermicelli and spaghetti.
