So he who shares my opinion about horse-breaking will, of course, send his colt out. Still he should put in writing what the horse is to know when he is returned, just as when he apprentices his son to a profession. For these articles will serve as notes to remind the horse-breaker of what he must attend to if he is to get his money. Still, care must be taken that the colt is gentle, tractable, and fond of man when he is sent to the horse-breaker. That sort of business is generally done at home through the groom, if he knows how to contrive that hunger and thirst and horseflies are associated by the colt with solitude, while eating and drinking and delivery from irritation come through man’s agency. For in these circumstances a foal is bound not only to like men, but to hanker after them.
