Slowly this old colonial system broke down. It became impossible to keep in political subjection millions of men across the seas of the same vigorous race. This the American Revolution drove home and the Canadian insurrections of 1837 again made unmistakable. In the views of most men it came to appear unprofitable, even if possible. Gradually the ideas of Adam Smith and Pitt and Huskisson, of Cobden and Bright and Peel, took possession of the English mind. Trade monopolies, it now was held, hampered more than they helped, even if costless. But when maintained at heavy expense, at cost of fortification and diplomatic struggle and war, they became worse than useless, a drag on the development of both colony and mother country. So the fetters which impeded trade and navigation were discarded. There followed, from the forties onward, a period of drift, of waiting for the coming separation. When the trade monopoly which was the object of empire ceased, most men in Britain reasoned that the end of the Empire, {130} in so far as it included colonies settled by white men, could not be far distant. Yet the end did not come. Though Radical politicians and publicists urged 'cutting the last link of connection'; though Conservative statesmen damned 'the wretched colonies' as 'millstones about our necks'; though under-secretaries said farewell to one 'last' governor-general after another and the London _Times_ bade Canadians 'take up your freedom, your days of apprenticeship are over'; in spite of all, the colonies lingered within the fold. Some dim racial instinct, the force of momentum, or the grip of inherited obligations, kept them together until gradually the times changed and the stage was set for another scene. Alike in the motherland and in the colonies men had stumbled upon the secret of empire--freedom. Expecting the end to come soon, the governing powers in London had ruled with a light rein, consenting to one colonial demand after another for self-government. In these years of salutary neglect the twofold roots of imperial connection had a chance to grow. The colonies rose to national consciousness, and yet, in very truth because of their freedom, and the absence of the {131} friction a centralizing policy would have entailed, they retained their affection and their sympathy for the land of their ancestors. Thus the way was prepared for the equal partnership which it has been the task of these later years to work out.
