Bastards of the BICORN COW are indicated precisely as in the preceding--by _the size_ of the spots of ascending hair, above the escutcheon and by the sides of the vulva (F, F, fig. 18). Bastards of the DEMIJOHN COW are distinguished precisely as the two preceding--_size of the streaks_ (fig. 18). The SQUARE ESCUTCHEON COW indicates bastards, by a streak of hair at the right of the vulva (fig. 19). When that ascending hair is coarse and bristly, it is a sure evidence that the animal is a bastard. LIMOUSINE COWS show their bastards precisely as do the CURVELINE and BICORN, by the size of the ascending streaks of hair, on the right and left of the vulva. (Fig. 19.) Bastards of the HORIZONTAL CUT COWS have no escutcheon whatever. By this they are always known. Some bastards are good milkers until they get with calf, and then very soon dry up. Others are poor milkers. Those with coarse hair and but little of it, in the escutcheon, give poor, watery milk. Those of fine, thick hair will give good milk. BULLS have escutcheons of the same shape as the cows, but on a smaller scale. Whenever there are streaks of descending hair bristling up among the ascending hair of the escutcheon, rendering it quite irregular and rough in its appearance, the animal is regarded as a bastard. Never put a cow to any bull that has not a regular, well-defined, and smooth escutcheon. This is as fully as we have room to go into M. Guenon's details. We fear this will fall into the hands of many who will not take the pains to master even these distinctions. To those who will, we trust they will be found plain, and certain in their results. From all this, one thing is certain, and that is of immense value to the farmer: it is, that on general principles, without remembering the exact figure of one of the indications above given, or one of the arbitrary terms it has been necessary to use, any man can tell the quality and quantity of milk a cow will give, and the time she will give milk, with sufficient accuracy to buy no cow and raise no heifer that will not be a profitable dairy cow, if that is what he desires. The rules by which these things may be known are the following: No cow, of any class, is ever a good milker, that has not a large surface of hair growing upward from the teats and covering the inner surface of the thighs, and extending up toward or to the tail. No cow that is destitute of this mark, or only has a very small one, is ever a good milker. Every cow having a scanty growth of coarse hair in the above mark will only give poor, watery milk; and every cow having a thick growth of fine hair on the escutcheon, or surface where it ascends, and considerable dandruff, will always give good rich milk, and be good for butter and cheese. Every cow on which this mark is small will give but little milk, and dry up soon after getting with calf, and is not fit to be kept.
