Having completed our review of the historical relations, we are now in a position to inquire how nearly the self-governing Dominions have already approached in actual fact to their theoretical equality with the mother-country. I prefer, for distinctness sake to add the epithet “Self-governing”; for they form only a part of the King's “Dominions” in the wide older sense of that word. The Imperial Conference of 1907 introduced a new and narrower sense, in which it is now limited to such Dominions as have Responsible Government. (Canada in 1867 desired to be called a “Kingdom,” but it was feared that the United States would resent it.)
