Since these significant words were written half a century ago, Canadians have been steadily working out the principles of parliamentary government as understood and explained by Lord Elgin, and have had abundant opportunities of contrasting their experiences with those of their neighbours under a system in many respects the very reverse of that which has enabled Canada to attain so large a measure of political freedom and build up such prosperous communities to the north of the republic, while still remaining in the closest possible touch with the imperial state. I propose now to close this book with some comparisons between the respective systems of the two countries, and to show that in this respect as in others Lord Elgin proved how deep was his insight into the working of political institutions, and how thoroughly he had mastered the problem of the best methods of administering the government of a great colonial dependency, not solely with a regard to its own domestic interests but with a view of maintaining the connection with the British Crown, of which he was so discreet and able a servant. It is especially important to Canadians to study the development of the institutions of the United States, with the view of deriving benefit from their useful experiences, and avoiding the defects that have grown up under their system. All institutions are more or less on trial in a country like Canada, which is working out great problems of political science under decided advantages, since the ground is relatively new, and the people have before them all the experiences of the world, especially of England and the United States, in whose systems Canadians have naturally the deepest interest. The history of responsible government affords another illustration of a truth which stands out clear in the history of nations, that those constitutions which are of a flexible character, the natural growth of the experiences of centuries, and which have been created by the necessities and conditions of the times, possess the elements of real stability, and best ensure the prosperity of a people. The great source of the strength of the institutions of the United States lies in the fact that they have worked out their government in accordance with certain principles, which are essentially English in their origin, and have been naturally developed since their foundation as colonial settlements, and whatever weaknesses their system shows have chiefly arisen from new methods, and from the rigidity of their constitutional rules of law, which separate too sharply the executive and the legislative branches of government. Like their neighbours the Canadian people have based their system on English principles, but they have at the same time been able to keep pace with the progress of the unwritten constitution of England, to adapt it to their own political conditions, and to bring the executive and legislative authorities to assist and harmonize with one another.
