The same rule applies with equal force to horse or cattle breeding, and the position as a breeder of any man who would use a half bred stallion or mongrel bull in his stud or herd would be quickly and properly estimated by the general public, As in the animal, so also in the vegetable king dom. The gardener improves the quality of his plants and flowers by careful cultiva tion and selection, but the grain grower seems content year after year to sow seed the vitality of which has been impaired by deterioration in the fertility of the land on which it is grown. If he purchases the grain it is enough for him to know that he has obtained it cheaply; he does not trouble about the quality of the soil on which it was grown, aod be takes no pains to free it from any weed seeds which it may contain. More than likely the seed which he scattered on his land is of three or four different varieties, some of which ripen early, others late, yet all are har vested at the sanae time, the result; being a falling off in the yield and an inferior sample of grain. How seldom do we find-that any special attention is given to cleaning seed. In the northern districts, where w.heat Iβ the staple product, and the stripper the most generally used harvester, the usual prac tice is to reserve a sufficient quantity of grain from the general crop for the following year's seed requirements. The grain has been run once through the winnower, which, good machine though it undoubtedly is in its pre sent form, is altogether incapable of extracting all the wild oats or cracked and inferior grain at the one operation. Yet no further trouble is taken, and farmers wonder why it is that their crops stool so badly or the new land so quickly becomes a nursery for wild oats and other weeds. The finding of a corn screen on a farm id a novel experience to an agricul sultural reporter, and the farmer's remedy for the inferiority of lm seed is to sow 60 thickly as to make allowance for misses or weak ness of growth.
