"Doubtless the art of breeding and of feeding cattle consists in getting the maximum profit out of those things from which the very name of money is derived, for our word for money (_pecunia_) comes from _pecus_, cattle, which is the foundation of all wealth. "Our enquiry may be divided into nine subjects, or three parts each with three subdivisions, namely: (i) concerning small cattle, of which the three kinds are sheep, goats and swine: (2) concerning large cattle, which are likewise divided by nature into three species, neat cattle, asses and horses: and (3) concerning those instruments of animal husbandry which are not kept for profit but for convenience, namely: mules, dogs and shepherds. Each of these nine subjects must be considered under nine heads: (a) four relating to the acquisition of cattle, (b) four to the care of them, and (c) one which has to do with all the others. So there are at least eighty-one chapters for discussion of the subject, all indispensable and all of great importance. "Under the head (a) of acquisition, it is first of all necessary, to enable you to buy good live stock, that you should know at what age it is best to buy and to keep each different kind. For instance, you may buy neat cattle for less money before they are a year old and after they are ten, because they begin to breed at two or three years and leave off soon after the tenth year, the beginning and the end of the life of all live stock being sterile. The second consideration under this head is a knowledge of the conformation of each kind of cattle and what it should be, for this is of great importance in determining the value of all animals. Thus experienced stockmen buy cattle with black horns rather than white, large goats rather than small, and swine with long bodies and short heads. The third consideration under this head is to make sure of the breeding. On this account the asses of Arcadia are celebrated in Greece, as are those of Reate in Italy, so that I remember an ass that brought sixty thousand sesterces, and a four-in-hand team at Rome that was held at four hundred thousand. The fourth consideration is of the legal precautions to be observed in buying live stock, for in order that title may pass from one to another certain formalities must intervene, since neither a contract nor even the payment of the purchase money suffices in all cases to transfer a title: thus in buying you some times stipulate that the animal is in good health, some times that it comes out of a healthy flock or herd, and some times no stipulation at all is made.
