The first object which saluted my eyes when I arrived on the coast, was the sea, and a slave ship, which was then riding at anchor, and waiting for its cargo. These filled me with astonishment, which was soon converted into terror, when I was carried on board. I was immediately handled, and tossed up to see if I were sound, by some of the crew; and I was now persuaded that I had gotten into a world of bad spirits, and that they were going to kill me. Their complexions, too, differing so much from ours, their long hair, and the language they spoke (which was very different from any I had ever heard), united to confirm me in this belief. Indeed, such were the horrors of my views and fears at the moment, that, if ten thousand worlds had been my own, I would have freely parted with them all to have exchanged my condition with that of the meanest slave in my own country. When I looked round the ship too, and saw a large furnace of copper boiling, and a multitude of black people of every description chained together, every one of their countenances expressing dejection and sorrow, I no longer doubted of my fate; and, quite overpowered with horror and anguish, I fell motionless on the deck and fainted...O, ye nominal Christians! might not an African ask you — Learned you this from your God, who says unto you, Do unto all men as you would men should do unto you? Is it not enough that we are torn from our country and friends, to toil for your luxury and lust of gain? Must every tender feeling be likewise sacrificed to your avarice ?
