These vertebrates, as well as an infinity of other life-forms—animal and vegetable, marine, terrestrial, and aërial—were the products of unguided evolution acting on life-cells made by the Old Ones but escaping beyond their radius of attention. They had been suffered to develop unchecked because they had not come in conflict with the dominant beings. Bothersome forms, of course, were mechanically exterminated. It interested us to see in some of the very last and most decadent sculptures a shambling primitive mammal, used sometimes for food and sometimes as an amusing buffoon by the land dwellers, whose vaguely simian and human foreshadowings were unmistakable. In the building of land cities the huge stone blocks of the high towers were generally lifted by vast-winged pterodactyls of a species heretofore unknown to palaeontology.
