The Norman strains of horses retain certain interesting indications of their ancient lineage and occupation. As appears to be common with old breeds, the stock is readily maintained. It breeds true to its ancestry, with little tendency to those aberrations so common in the newly instituted varieties. When crossed with other strains, the effect of the intermixture of this strong blood is distinctly traceable for many generations. In their mental habits these creatures still appear to show something of the effects of their old use in war; it is a valiant race, less given to insane fear than other strains, and, even under excitement, more controllable than the most of their kindred. So far as I have been able to learn, they seem singularly free from those wild panics which are so common among our ordinary horses. It does not seem to me fanciful to suppose that these qualities were bred in the stock during the centuries of experience with the confusion of battle-fields and tournaments. [Illustration: Exercising the Thoroughbreds] The horse, in common with the other domesticated animals varying readily in the hands of the breeder, undergoes a certain spontaneous change which in a way corresponds to the physiography of the region in which it is bred. At first sight it may seem as if these alterations are due to the admixture of previously existing varieties, or to the institution of peculiarities by some process of selection. I am, however, well convinced that these variations are in good part due to a direct influence from the environment. Thus in our high northern lands there is a distinct and spontaneous reduction in size of the creatures, which attains its farthest point in the Shetland pony. Again, as we go toward the tropics, a like though less conspicuous decrease in bulk is observable. The largest animals of the species develop in the middle latitudes, the realm where the form appears to have acquired its characters. The speed with which these local variations are made is often great. Thus the horses of Kentucky have, in about a century, acquired a certain stamp of the soil which makes it possible, in most cases, for the observer to identify an individual as from that State, though he may find it in a field a thousand miles away. The defining indications are not limited altogether to bodily form, but are shown in what might seem trifling features of carriage and behavior. The difference between the horses of Great Britain and those of the United States seems to me, from repeated observations, to be quite as great as that separating the men of the two realms. I believe that if a lot of a thousand, taken in equal parts from either land, were put together, a person well accustomed to taking account of these animals could separate them into two herds, with less than ten per cent. of error. It is doubtful if a more perfect selection could be made if the same experiment were tried on an equal number of men, provided the indices
