If the seed be prepared in the way already described, the disease will rarely prevail to such an extent as to affect materially the value of the crop. Rust is another very prevalent disease, nearly allied to the mildew. It appears in the form of a brownish dust upon the stem, leaves, and seed, and, like the others, is produced by a parasitical plant. The roots of the wheat plant are liable to be attacked by grubs and worms, the larvae of various beetles ; among these are the wire-worm, and the red-headed large white grub, the larvae of the May-bug, cockchafFer, or black bug. These often do much injury, and late ploughing is the best mode of destroying them, by thus exposing them to the frosts ; when they appear in the summer, they are sometimes destroyed by being attracted towards large fires, kindled for the purpose, and perishing in them. But the insects that attack the wheat while growing and in the ear are by far the most powerful enemies which it encounters. These insects are the Hessian fly and the wheat fly. The former has a black head, thorax, and wings, with a brownish body; the latter is of smaller size, of a yellow color, and clear wings. (See Chapter on Insects.) BARLEY. Classification. — The natural classification of barley by the ear is obvi- ously of three kinds, — four-rowed, six-rowed, and two-rowed, as in Fig. 43. In Fig. 43, a is the four-rowed, or here or bigg; c is the six-rowed; and b the two-rowed. When classified by the grain, there are two kinds, here or bigg, and barley; and though both are awned, they are sufficiently marked to consti- tute distinct varieties. In the here (Fig. 42, a), the median line of the bosam is so traced as to give the grain a twisted form, by which one of its si
