his favour, and put him in office, one of England’s strongest ministers; during his long administration, broken only for one month in 20 years, he greatly raised the importance of the Commons, stamped out direct corruption in the House, and abolished many sinecures; he revised taxation, improved the collection of revenue and the issue of loans, and set the finances in a flourishing condition; he reorganised the government of India, and aimed strenuously to keep England at peace; but his abandonment of parliamentary reform and the abolition of the slave-trade suggests that he loved power rather than principles; his Poor-Law schemes and Sinking Fund were unsound; he failed to appreciate the problems presented by the growth of the factory system, or to manage Ireland with any success; on the outbreak of the French Revolution he failed to understand its significance, did not anticipate a long war, and made bad preparations and bad schemes; his vacillation in Irish policy induced the rebellion of 1798; by corrupt measures he carried the legislative union of 1801, but the king refused to allow the Catholic emancipation he promised as a condition; Viscount Melville was driven from the Admiralty on a charge of malversation, his own health broke down, and the victory of Trafalgar scarcely served to brighten his closing days; given to deep drinking, and culpably careless of his private moneys, he yet lived a pure, simple, amiable life; with an overcharged dignity, he was yet an attractive man and a warm friend; England has had few statesmen equal to him in the handling of financial and commercial problems, and few orators more fluent and persuasive than the great peace minister.
