It is not found, therefore, in any out fall sown, crops, and is less abundant in rye than wheat, because of the greater hardiness of rye as with wheat. The above habits are sufficient to explain the abun- dant development of this plant in wheat which has been injured by winter killing or by the Hessian fly when the sowing of clean seed has not been continuously practiced. The introduc tion of chess seed in the grain seriously injures its market value, as the chess must be removed before the wheat is ground. The machinery for this purpose in large milling establish- ments has reached great perfection. Hackel says that flour containing an ad- mixture of chess willbe dark colored, remain moist and is narcotic. 1 Chess can be removed rather readily from the seed wheat by the ordi- nary fanning mills. When wheat is treated for smut, if the grains are stirred in the solu tion, any remaining chess seeds will come to the surface and can be skimmed off. 140. Darnel.—Darnel belongs to the same tribe of grasses as wheat, to the same genus as perennial and Italian rye grass. Unlike these grasses, however, it is an annual. It occurs in grain crops of Europe and is also reported occurring in wheat fields of California, where it is known as chess. This plant is supposed to be the "tares'' spoken of in the Bible. Like chess it is said to contain a narcotic principle which causes eruptions, tremb- ling and confusion of sight in man, and in flesh-eating animals, and very strongly in rabbits, but does not affect swine, horned cattle or Darnel may bO removed from wheat intended for seed by the same
