Sir Charles Prestwood Lucas, A history of Canada, 1763-1812 (1909)
“ In those parts of the world which have been settled and not merely conquered by Europeans, and which are still British possessions, in British North America, Australasia, and South Africa, there has been on the whole parity of progress. No one of the three groups of colonies has in wealth and population wholly out-distanced the others. This fact has unquestionably made for strength and permanence in the British Empire, and it is equally beyond question that the spread of colonization within the Empire would have been wanting, had Great Britain retained her old North American colonies. ”
