But the fairest test of its fitness for the dairy is to be found in the estimation in which distinguished Devon breeders themselves have held it in this respect. A scale of points of excellence in this breed was established, some time ago, by the best judges in England; and it has since been adopted, with but slight changes, in this country. These judges, naturally prejudiced in favor of the breed, if prejudiced at all, made this scale to embrace one hundred points, no animal to be regarded as perfect unless it excelled in all of them. Each part of the body was assigned its real value in the scale: a faultless head, for instance, was estimated at four; a deep, round chest, at fifteen, &c. If the animal was defective in any part, the number of points which represented the value of that part in the scale was to be deducted pro rata from the hundred, in determining its merits. But in this scale the cow is so lightly esteemed for the dairy, that the udder, the size and shape of which is of the utmost consequence in determining the capacity of the milch cow, is set down as worth only _one point_, while, in the same scale, the horns and ears are valued at two points each, and the color of the nose, and the expression of the eye, are valued at four points each. Supposing, therefore, that each of these points were valued at one dollar, and a perfect North Devon cow was valued at one hundred dollars; then another cow of the same blood, and equal to the first in every respect except in her udder, which is such as to make it certain that she can never be capable of giving milk enough to nourish her calf, must be worth, according to the estimation of the best Devon breeders, ninety-nine dollars! It is safe, therefore, to say that an animal whose udder and lacteal glands are regarded, by those who best know her capacities and her merits, as of only one quarter part as much consequence as the color of her nose, or half as much as the shape and size of her horns, cannot be recommended for the dairy. The improved North Devon cow may be classed, in this respect, with the Hereford, neither of which has well-developed milk-vessels--a point of the utmost consequence to the practical dairyman. * * * * * The list of pure-bred races in America may be said to end here; for, though other and well-established breeds, like the long-horns, the Galloways, the Spanish, &c., have, at times, been imported, and have had some influence on our American stock, they have not been kept distinct to such an extent as to have become the prevailing stock of any particular section, so far as I am aware, and hence a notice of them properly comes in the next chapter.
