the provinces subject to its dominion, consist, first, in the military force which they furnish for its defence; and, secondly, in the revenue which they furnish for the support of its civil government. The Roman colonies furnished occasionally both the one and the other. The Greek colonies, sometimes, furnished a military force; but seldom any revenue. They seldom acknowledged themselves subject to the dominion of the mother city. They were generally her allies in war, but very seldom her subjects in peace.
The European colonies of America have never yet furnished any military force for the defence of the mother country. Their military force has never yet been sufficient for their own defence; and in the different wars in which the mother countries have been engaged, the defence of their colonies has generally occasioned a very considerable distraction of the military force of those countries. In this respect, therefore, all the European colonies have, without exception, been a cause rather of weakness than of strength to their respective mother countries.
