The country is, in general, uneven and hilly, cut up in every direction by small valleys watered by springs or small brooks flowing into the rivers above named. All these valleys, no matter of what extent, are natural meadows, and the most of them rich and fertile. But drainage could here be usefully applied everywhere, to rid them of their surplus humidity, and to purge them of their too abundant aquatic plants. The finest valley is that watered by the Huisne, which is second to none in France for length, extent, richness, and beauty of sites. Here are situated Nogent-le-Rotrou, Condé, Regmalard, Boissy, Corbon, Mauves, Pin-la-Garenne, Reveillon, etc., etc.,—all centers renowned for the beauty of their horses. The land is generally clayey, lying upon a calcareous subsoil of the secondary formation. Some portions are silicious, the high and hilly points always so. The Percheron country contains rather few meadows, in proportion to the total surface of the soil, and to this circumstance, probably, is due the superiority of its horses. Here the rearing takes place in the stable and the brood-mare is found under the hand of the breeder. The idea of making use of her comes naturally to his mind. He works and feeds her well. All the secret of his breeding lies in these few words. Here, for many years, agriculture has flourished; artificial meadows are everywhere cultivated with success, and are necessary to produce the enormous quantity of fodder consumed by the number of horses raised.
