It would, however, be unjust to Mr. Winthrop not to recognize that the chief reason for his selection as Speaker was his pre-eminent fitness for the important post. He was a young man, and, other conditions being equal, young men have been uniformly preferred for the arduous duties of the Chair. From the organization of the government the speakers, at the time of their first election, have been under forty-five years of age,--many, indeed, under forty. In only four instances have men been selected beyond the age of fifty. Mr. Clay when first chosen was but thirty-four, Mr. Polk thirty-nine, Mr. John Bell thirty-seven, Mr. Howell Cobb thirty- three, and Mr. Robert M. T. Hunter, the youngest man ever elected Speaker, was but thirty. Mr. Winthrop was thirty-eight. He was bred to the law in the office of Mr. Webster, but at twenty-five years of age entered political life as a member of the Massachusetts House of Representatives. He was soon after promoted to the speakership of that body, where he earned so valuable a reputation as a presiding officer that some of his decisions have been quoted as precedents in the National House, and have been incorporated in permanent works on Parliamentary Law. He was chosen in Congress when he was but thirty, and was in his fifth term in the House when he was advanced to the Speakership. As an orator he was always graceful and effective, but never took high rank in the House as a debater. His early life gave promise of a long public career in Massachusetts as the successor of the older Whig leaders who were passing off the stage. He followed Mr. Webster in the Senate for a brief period, when the latter became Secretary of State under Mr. Fillmore. His conservative tendencies on the Slavery question, however, were not in harmony with the demands of public opinion in Massachusetts, and in 1851 he was defeated for the governorship by George S. Boutwell, and for the senatorship by Charles Sumner. Mr. Winthrop's political career closed when he was forty-two years of age. WHIGS ABANDON THE WILMOT PROVISO.
