Gulliver's Travels Full Text: Part 4, Chapter 8 : Page 4
When the matron _Houyhnhnms_ have produced one of each sex, they no longer accompany with their consorts, except they lose one of their issue by some casualty, which very seldom happens; but in such a case they meet again; or when the like accident befalls a person whose wife is past bearing, some other couple bestow on him one of their own colts, and then go together again until the mother is pregnant. This caution is necessary, to prevent the country from being overburdened with numbers. But the race of inferior _Houyhnhnms_, bred up to be servants, is not so strictly limited upon this article: these are allowed to produce three of each sex, to be domestics in the noble families.
Courtship, love, presents, jointures, settlements have no place in their thoughts, or terms whereby to express them in their language. The young couple meet, and are joined, merely because it is the determination of their parents and friends; it is what they see done every day, and they look upon it as one of the necessary actions of a reasonable being. But the violation of marriage, or any other unchastity, was never heard of; and the married pair pass their lives with the same friendship and mutual benevolence, that they bear to all others of the same species who come in their way, without jealousy, fondness, quarrelling, or discontent.
In educating the youth of both sexes, their method is admirable, and highly deserves our imitation. These are not suffered to taste a grain of oats, except upon certain days, till eighteen years old; nor milk, but very rarely; and in summer they graze two hours in the morning, and as many in the evening, which their parents likewise observe; but the servants are not allowed above half that time, and a great part of their grass is brought home, which they eat at the most convenient hours, when they can be best spared from work.
