They engaged him to act for them. He himself interested Mr. Wilberforce in the matter. The shipmasters in that trade were the greatest miscreants, and guilty of every barbarity to their own crews. Clarkson went to Bristol, made himself acquainted with the interior of the slave-ships and the details of the trade. The facts confirmed his sentiment, “that Providence had never made that to be wise which was immoral, and that the slave-trade was as impolitic as it was unjust;”[107] that it was found peculiarly fatal to those employed in it. More seamen died in that trade in one year than in the whole remaining trade of the country in two. Mr. Pitt and Mr. Fox were drawn into the generous enterprise. In 1788, the House of Commons voted Parliamentary inquiry. In 1791, a bill to abolish the trade was brought in by Wilberforce, and supported by him and by Fox and Burke and Pitt, with the utmost ability and faithfulness; resisted by the planters and the whole West Indian interest, and lost. During the next sixteen years, ten times, year after year, the attempt was renewed by Mr. Wilberforce, and ten times defeated by the planters. The king, and all the royal family but one, were against it. These debates are instructive, as they show on what grounds the trade was assailed and defended. Everything generous, wise and sprightly is sure to come to the attack. On the other part are found cold prudence, bare-faced selfishness and silent votes. But the nation was aroused to enthusiasm. Every horrid fact became known. In 1791, three hundred thousand persons in Britain pledged themselves to abstain from all articles of island produce. The planters were obliged to give way; and in 1807, on the 25th March, the bill passed, and the slave-trade was abolished.
