“But it is now time to explain to you the mutual intercourse of this people, their commerce, and the rules by which all things are distributed among them.
“As their cities are composed of families, so their families are made up of those that are nearly related to one another. Their women, when they grow up, are married out, but all the males, both children and grand-children, live still in the same house, in great obedience to their common parent, unless age has weakened his understanding, and in that case he that is next to him in age comes in his room; but lest any city should become either too great, or by any accident be dispeopled, provision is made that none of their cities may contain above six thousand families, besides those of the country around it. No family may have less than ten and more than sixteen persons in it, but there can be no determined number for the children under age; this rule is easily observed by removing some of the children of a more fruitful couple to any other family that does not abound so much in them. By the same rule they supply cities that do not increase so fast from others that breed faster; and if there is any increase over the whole island, then they draw out a number of their citizens out of the several towns and send them over to the neighbouring continent, where, if they find that the inhabitants have more soil than they can well cultivate, they fix a colony, taking the inhabitants into their society if they are willing to live with them; and where they do that of their own accord, they quickly enter into their method of life and conform to their rules, and this proves a happiness to both nations; for, according to their constitution, such care is taken of the soil that it becomes fruitful enough for both, though it might be otherwise too narrow and barren for any one of them. But if the natives refuse to conform themselves to their laws they drive them out of those bounds which they mark out for themselves, and use force if they resist, for they account it a very just cause of war for a nation to hinder others from possessing a part of that soil of which they make no use, but which is suffered to lie idle and uncultivated, since every man has, by the law of nature, a right to such a waste portion of the earth as is necessary for his subsistence. If an accident has so lessened the number of the inhabitants of any of their towns that it cannot be made up from the other towns of the island without diminishing them too much (which is said to have fallen out but twice since they were first a people, when great numbers were carried off by the plague), the loss is then supplied by recalling as many as are wanted from their colonies, for they will abandon these rather than suffer the towns in the island to sink too low.
