44 We may here observe that if domestic slavery really increased populousness, it would be an exception to the general rule, that the happiness of any society and its populousness are necessary attendants. A master, from humour or interest, may make his slaves very unhappy, and yet be careful, from interest, to increase their number. Their marriage is not a matter of choice with them, no more than any other action of their life.

45 Ten thousand slaves in a day have been often sold for the use of the Romans at Delus in Cilicia.—Strabo, lib. 14.
