These observations which seem all to concur in proving that in horses the male has greater influence than the female on their progeny, do not appear sufficient to establish this fact in an indisputable manner. It is not impossible, but that these observations may subsist, and yet in general the mare may contribute as much as the horse to the production of their issue; for it is not astonishing that stallions, always chosen out of a great number, generally brought from warm climates, high-fed, kept and managed with great care, should have the sway in generation over common mares, bred in a cold climate, and frequently obliged to labour. But if the beautiful mares of warm countries were selected out, managed with equal care, and covered by common horses of our own country, I think there cannot be a doubt but the semblance of the females would be superior to the males, and that among horses, as well as in the human species, there would be an equality in the influence of the male and female in their young, supposing a similarity in the accordant circumstances. This appears natural, and the more probable, as it has been remarked in studs that an equal number of male and female foals are bred, which proves that, at least as far as regards the sex, the female has equal influence. Mares are generally in season nine days after their delivery, when the horse ought to be taken to them, in the choice of which attention should be paid to his figure being perfect in those parts wherein the mare may be deficient. The breed of horses, at least such as are handsome, require an infinite degree of care and attention, and is accompanied with considerable expence. The mares and foals should be kept in rich inclosures, and if alternately grazed by oxen and horses it will be an advantage, as the former constantly repairs the injuries done by the latter; each of these inclosures should contain a pond, which is preferable to a running stream, and be also provided with trees to shelter them from the heat of the sun; when, however, the winter season commences they should be taken into the stable and be well supplied with hay. The stallion should always be kept in the house; he should be fed with more straw than hay, and be moderately exercised until the season for covering, when he should be fed plentifully, though with nothing but common food. If managed with proper care he may be led to 15 or 18 mares with success in the course of the season, which, as we before observed, continues from the end of March to the end of June.
