In this complex empire of ours the problem presents itself in many shapes, and each must be studied and dealt with according to its character. There is the broad distinction between colonies and conquered countries. Colonists are part of ourselves. Foreigners attached by force to our dominions may submit to be ruled by us, but will not always consent to rule themselves in accordance with our views or interests, or remain attached to us if we enable them to leave us when they please. The Crown, therefore, as in India, rules directly by the police and the army. And there are colonies which are neither one nor the other, where our own people have been settled and have been granted the land in possession with the control of an insubordinate population, themselves claiming political privileges which had to be refused to the rest. This was the position of Ireland, and the result of meddling theoretically with it ought to have taught us caution. Again, there are colonies like the West Indies, either occupied originally by ourselves, as Barbadoes, or taken by force from France or Spain, where the mass of the population were slaves who have been since made free, but where the extent to which the coloured people can be admitted to share in the administration is still an unsettled question. To throw countries so variously circumstanced under an identical system would be a wild experiment. Whether we ought to try such an experiment at all, or even wish to try it and prepare the way for it, depends perhaps on whether we have determined that under all circumstances the retention of them under our own flag is indispensable to our safety.
