Carter could now distinguish moving figures on the noisome wharves ahead, and the better he saw them the worse he began to fear and detest them. For they were not men at all, or even approximately men, but great greyish-white slippery things which could expand and contract at will, and whose principal shape—though it often changed—was that of a sort of toad without any eyes, but with a curious vibrating mass of short pink tentacles on the end of its blunt, vague snout. These objects were waddling busily about the wharves, moving bales and crates and boxes with preternatural strength, and now and then hopping on or off some anchored galley with long oars in their forepaws. And now and then one would appear driving a herd of clumping slaves, which indeed were approximate human beings with wide mouths like those merchants who traded in Dylath-Leen; only these herds, being without turbans or shoes or clothing, did not seem so very human after all. Some of the slaves—the fatter ones, whom a sort of overseer would pinch experimentally—were unloaded from ships and nailed in crates which workers pushed into the low warehouses or loaded on great lumbering vans.
