On many of the great questions with which the American people had to deal for the last thirty years of his life,--from 1844 to 1874--he was the leader and guide. His speeches on these subjects, contained in these volumes, were the speeches which attracted widest public attention at the time. They contained the arguments which convinced the public mind. They are probably, in most cases, the only ones remembered now. Toward the close of his life he gave much study to the questions of finance and currency. If his life had been spared he doubtless would have been foremost in conducting the country in the path of financial safety and integrity. The titles of the following speeches, to which many others might be added, suggest the principal subjects with which he dealt. VOL. I. The True Grandeur of Nations. July 4, 1845.
