A favorite trick of the slaver, fleeing from a man-of-war, was to throw over slaves a few at a time in the hope that the humanity of the pursuers would impel them to stop and rescue the struggling negroes, thus giving the slave-ship a better chance of escape. Sometimes these hapless blacks thus thrown out, as legend has it Siberian peasants sometimes throw out their children as ransom to pursuing wolves, were furnished with spars or barrels to keep them afloat until the pursuer should come up; and occasionally they were even set adrift by boat-loads. It was hard on the men of the navy to steel their hearts to the cries of these castaways as the ship sped by them; but if the great evil was to be broken up it could not be by rescuing here and there a slave, but by capturing and punishing the traders.
