We find their bones, and their stone weapons, and their crude paintings, in the caves of Cro-Magnon and Grimaldi and Altimira and Mas-d’Azil; the deep layers of horse and reindeer and mammoth bones at their feasting-place at Solutre.  We wonder how and whence a race so like our own came into a world of brutish sub-humans.

Just as we wonder, too, at the network of canals which radiate from the polar caps of our sister planet, and speculate on the possibility that they were the work of hands like our own.  And we concoct elaborate jokes about the “Men From Mars”—­ourselves.
