The name of Sir Louis Lafontaine is intimately associated in the public mind with that of his friend and associate Robert Baldwin. What the latter was in Upper Canada, such was Sir Louis in the Lower Province--the leader of a numerous, an exacting, and a not always manageable political party. These two statesmen were the leading spirits on behalf of their respective Provinces in two Governments which are known in history by their joint names. Their personal intimacy and active co-operation extended over only about ten years, but the bond of union between them during that period was closely knit, and their mutual confidence was complete. They fought side by side with perfect fealty to each other and to the State, and their retirement from public life was almost simultaneous. Their mutual relations, both public and private, were marked by an almost chivalrous courtesy and respect, and even after they had ceased to take part in the struggles with which both their names are identified, they continued to think and speak of each other with an enthusiasm which was not generally supposed to belong to the nature of either. Sir Louis was in some respects the most remarkable man that Lower Canada has produced. Though he identified himself with many important measures of Reform, the temper of his mind, more especially during his latter years, was eminently aristocratic and Conservative. His disposition was not one that could properly be described as genial. He was not a perfect tactician, and had not the faculty of making himself "all things to all men." Coriolanus himself had not a more supreme contempt for "the insinuating nod" whereby the elector is wheedled out of his vote. His demeanour was generally somewhat cold and repellent, and though he was thoroughly honourable, and respected by all who knew him, he was not a man of many warm personal friends. In the sketch of Robert Baldwin's life we have given Sir John Kaye's estimate of that gentleman's character and aspirations, as reflected in the letters and papers of Lord Metcalfe. The estimate is so wide of the mark that our readers will probably be disposed to place little reliance upon Sir John's capability for gauging the public men of Canada. In the case of the subject of the present sketch, however, Lord Metcalfe's biographer has contrived to stumble upon a much more accurate judgment. Speaking of Mr. Lafontaine, during his tenure of office as Attorney-General for Canada East, in 1843, he tells us that "all his better qualities were natural to him; his worse were the growth of circumstances. Cradled, as he and his people had been, in wrong, smarting for long years under the oppressive exclusiveness of the dominant race, he had become mistrustful and suspicious; and the doubts which were continually floating in his mind had naturally engendered indecision and infirmity of purpose. But he had many fine characteristics which no evil circumstances could impair. He was a just and an honourable man.
