The usage of planting colonies was recommended by the great advantage and convenience which resulted from it. In dealing with the spoils of warfare their practice, no doubt, in a measure changed, so that in this respect they were not afterwards so liberal as they were at first; partly, because liberality did not seem so necessary when their soldiers were in receipt of pay; and, partly, because the spoils themselves being greater than before, they thought by their help so to enrich the public treasury as to be able to carry on their wars without taxing the city; and, in fact, by pursuing this course the public revenues were soon greatly augmented. The methods thus followed by the Romans in dividing plunder and in planting colonies had, accordingly, this result, that whereas other less prudent princes and republics are impoverished by war, Rome was enriched by it; nay, so far was the system carried, that no consul could hope for a triumph unless he brought back with him for the public treasury much gold and silver and spoils of every kind.
By methods such as these, at one time bringing their wars to a rapid conclusion by invasion and actual defeat, at another wearing out an enemy by protracted hostilities, and again by concluding peace on advantageous terms, the Romans continually grew richer and more powerful.
