Read the passage from "By the Waters of Babylon.”How shall I tell what I saw? There was no smell of man left, on stone or metal. Nor were there many trees in that wilderness of stone. There are many pigeons, nesting and dropping in the towers—the gods must have loved them, or, perhaps, they used them for sacrifices. There are wild cats that roam the god-roads, green-eyed, unafraid of man. At night they wail like demons but they are not demons. The wild dogs are more dangerous, for they hunt in a pack, but them I did not meet till later. Everywhere there are the carved stones, carved with magical numbers or words.
