The Duke of Argyle deserves more than a passing mention. Although comparatively a young man, he has already had a most creditable career, and given new lustre to an old and honored name. In politics he is a decided and consistent Liberal, and he merits the favorable consideration of all loyal Americans from the fact that he has not failed on every proper occasion to advocate our cause with such arguments as show clearly that he fully understands our position and appreciates the importance of the principles for which we are contending. It is a curious coincidence, that his style of address bears a close resemblance to what may be called the American manner. Rapid, but distinct, in utterance, facile and fluent in speech, natural and graceful in gesticulation, he might almost be transplanted to the halls of Congress at Washington without betraying his foreign birth and education. Lord Derby is undoubtedly the most skillful Parliamentary tactician and the most accomplished speaker in the House of Lords. In 1834, (when he was a member of the House of Commons,) Macaulay said of him, that "his knowledge of the science of parliamentary defence resembled an instinct." He is the acknowledged leader of the Tories or Conservatives in England, and dictates the policy of his party with absolute despotism. Belonging to one of the oldest peerages in the kingdom, having already filled some of the most important offices in Her Majesty's Government, occupying the highly honorable position of Chancellor of the University of Oxford, (as successor of the first Duke of Wellington,) an exact and finished scholar, enjoying an immense income, and the proprietor of vast landed estates, he may be justly considered one of the best types of England's aristocracy. He has that unmistakable air of authority without the least alloy of arrogance, that "pride in his port," which quietly asserts the dignity of long descent. As a speaker, his manner is impressive and forcible, with a rare command of choice language, an accurate and comprehensive knowledge of all subjects connected with the administration of public affairs, and that entire self-control which comes from life-long contact on terms of equality with the best society in Europe and a thorough confidence in his own mental resources. Lord Derby is preeminently a Parliamentary orator, and furnishes one of the unusual instances where a reputation for eloquence earned in the House of Commons has been fully sustained by a successful trial in the House of Lords.
