This difficulty may be supposed to have been more than ordinarily great. Many evils of a public nature, which existed in former times, were the offspring of ignorance and superstition, and they were subdued of course by the progress of light and knowledge. But the evil in question began in avarice. It was nursed also by worldly interest. It did not therefore so easily yield to the usual correctives of disorders in the world. We may observe also, that the interest by which it was thus supported, was not that of a few individuals, nor of one body, but of many bodies of men. It was interwoven again into the system of the commerce and of the revenue of nations. Hence the merchant--the planter--the mortgagee--the manufacturer--the politician--the legislator--the cabinet-minister--lifted up their voices against the annihilation of it. For these reasons the Slave-trade may be considered, like the fabulous hydra, to have had a hundred heads, every one of which it was necessary to cut off before it could be subdued. And as none but Hercules was fitted to conquer the one, so nothing less than extraordinary prudence, courage, labour, and patience, could overcome the other. To protection in this manner by his hundred interests it was owing, that the monster stalked in security for so long a time. He stalked too in the open day, committing his mighty depredations. And when good men, whose duty it was to mark him as the object of their destruction, began to assail him, he did not fly, but gnashed his teeth at them, growling savagely at the same time, and putting himself into a posture of defiance. We see then, in whatever light we consider the Slave-trade, whether we examine into the nature of it, or whether we look into the extent of it, or whether we estimate the difficulty of subduing it, we must conclude that no evil more monstrous has ever existed upon earth. But if so, then we have proved the truth of the position, that the abolition of it ought to be accounted by us as one of the greatest blessings, and that it ought to be one of the most copious sources of our joy. Indeed I do not know, how we can sufficiently express what we ought to feel upon this occasion. It becomes us as individuals to rejoice. It becomes us as a nation to rejoice. It becomes us even to perpetuate our joy to our posterity. I do not mean however by anniversaries, which are to be celebrated by the ringing of bells and convivial meetings, but by handing down this great event so impressively to our children, as to raise in them, if not continual, yet frequently renewed thanksgivings, to the great Creator of the universe, for the manifestation of this his favour, in having disposed our legislators to take away such a portion of suffering from our fellow-creatures, and such a load of guilt from our native land.
