The American horses, in time, met the wild horses, and then men noticed that they were very different animals. The wild horse is smaller and more muscular, he has stronger and stouter limbs, a larger head, and a more bushy mane and tail. His ears are longer and more inclined to lie back on his head, his feet are smaller and more pointed in front, and his hair is rougher and thicker. His color is often curiously mixed in black and white dots and flecks, like some circus horses that you may have seen; and, if his color is uniform, it is generally dark red or deep gray or mouse color. These mustangs are quite wild, and have no fixed feeding-ground. They scamper in droves over the rolling prairies and pampas, and sleep at night in such dry places as they can find. They keep in companies for protection against bears or other wild animals, and if they are attacked, they put their noses together and form a circle with their heels out, as if they had been told of the old Spanish fighting days, and of the soldiers forming with their pikes solid squares to resist attacks of cavalry.
