George’s first voyage was on a slaver, and he wished himself dead many a time before it was over, — and ever after would talk like a man beside himself, if the subject was named. He declared that the gold made in it was distilled from human blood, from mothers’ tears, from the agonies and dying groans of gasping, suffocating men and women, and that it would sear and blister the soul of him that touched it; in short, he talked as whole-souled, unpractical fellows are apt to talk about what respectable people sometimes do. Nobody had ever instructed him that a slaveship, with a procession of expectant sharks in its wake, is a missionary institution, by which closely. packed heathens are brought over to enjoy the light of the Gospel.
