All animals are more readily judged correctly, and the system can be learned more easily, in summer than in winter, both on old and young; for then the winter coat of hair is off, and the hair is shorter, and the escutcheon is more easily perceived. The skin, also, is more natural and soft, and the hair is usually not so harsh to the feel; and the cows are cleaner, and all marks or blemishes more quickly seen. How to Apply the System Practically. We will now proceed to apply the foregoing rules and hints practically. In doing so, we may repeat some that has been before said, but it will only impress it the stronger in the mind of the learner. This classification embraced all the kinds of cows known to Guenon, each individual escutcheon corresponding with one of the orders of those classes. The _class_, the _order_ and the _size_ of an animal indicate her yield of milk, and this will always be found to correspond with her escutcheon. Every cow has an escutcheon which can be recognized, and according as it is free from blemish or imperfection, just in that degree does she approach perfection in her class. Guenon, in the last edition of his work, has altered and simplified his classification somewhat, for he divided it into ten CLASSES, and six ORDERS to each class. He maintained his three grades of size. But our experience shows that the cows in this country do not vary so much in size as they probably do in France, for there they have the little Brittany cow, which is very small but good, and, of course, they have also cows as large as our Durhams or the Holsteins. Only this, bear in mind, that cows, as a general rule, all other things being equal, will vary in their yield somewhat according to their size; and in judging cows apply that rule, for it is part of Guenon’s system, and they will vary in the quality according to the breed. Well, then, for practical purposes, we need only study sixty _escutcheons_, that is ten different shapes called _Classes_, and six grades to each of those shapes, more or less perfect, which are called _Orders_. To these must be added ten more for a _Bastard_ to each class. And it is really necessary to study perfectly only the first four orders of each class and the _Bastard_ marks, as it is not worth while to purchase or pay much attention to any cows lower in the scale than the fourth order of any class. And to simplify it still more, you will notice the thigh escutcheons of the first orders have all nearly the same shovel shape, so that by remembering this you need only study the vertical portions to readily place the animals in their proper class.
