Once a van was hitched and driven off, and the, fabulous thing which drew it was such that Carter gasped, even after having seen the other monstrosities of that hateful place. Now and then a small herd of slaves dressed and turbaned like the dark merchants would be driven aboard a galley, followed by a great crew of the slippery toad-things as officers, navigators, and rowers. And Carter saw that the almost-human creatures were reserved for the more ignominious kinds of servitude which required no strength, such as steering and cooking, fetching and carrying, and bargaining with men on the earth or other planets where they traded. These creatures must have been convenient on earth, for they were truly not unlike men when dressed and carefully shod and turbaned, and could haggle in the shops of men without embarrassment or curious explanations. But most of them, unless lean or ill-favoured, were unclothed and packed in crates and drawn off in lumbering lorries by fabulous things. Occasionally other beings were unloaded and crated; some very like these semi-humans, some not so similar, and some not similar at all. And he wondered if any of the poor stout black men of Parg were left to be unloaded and crated and shipped inland in those obnoxious drays.
