He has not, it is true, the fine haunch and fine form of the shoulder, nor that swan-like neck which distinguishes the Arab; but it must not be forgotten that for ages he has been employed for draft purposes, and these habits have imparted to his bony frame an anatomical structure, a combination of levers adapted to the work he is called upon to perform. He has not, I again acknowledge, such a fine skin as the Arab, nor his prettily rounded, oval, and small foot; but we must remember the fact that he lives under a cold climate, upon elevated plains, where nature gives him for a covering a thicker skin and a warmer coat, and that he has been for ages stepping upon a moist, clayey soil. In all that remains in him, we recognize a heavy Arab, modified and remodeled by climate and peculiar circumstances. He has remained mild and laborious, like his sire; he is brought up, like him, in the midst of the family, and, like him, he possesses in a very high degree the faculty of easy acclimation. He acquires this in the midst of the numerous migrations he accomplishes in Perche, the counterpart of those that the type horse makes upon the sands of the desert. A final comparison, which has not, as yet, been sufficiently noticed, is, that, like the Arab, he has no need of being mutilated in order to be trained, managed and kept without danger. In a word, the Percheron, notwithstanding the ages which separate them, presents an affinity as close as possible with the primitive horse, which is the Arab. From this similarity of form and probable relationship, comes the thought of new alliances. But in order to form a more easy estimate of their effects, it will not be without interest to classify the horses with reference to their origin. This classification produces three very distinct groups: the primitive horse, the natural horse, and the compound horse. The _Primitive Horse_, oriental in its origin, is the pure Arabian horse; no other is acknowledged. During the time of the crusaders, as we have already said in our first part, in consequence of wars and all kinds of excursions, individuals of this race were spread over almost all parts of the globe. Although at first the prestige which their superior merits deserved led to their being bred in-and-in, these exiles were placed under different latitudes, in different atmospheric and hygienic conditions, which gradually modified their qualities and led to the degeneracy of the race. And it became more or less degenerate in proportion as the soil upon which the colts were foaled was colder, poorer, and more inhospitable; _for the horse is as much, and more, the son of the soil upon which he is foaled and reared as he is of his sire and dam_.
