"We know more than that," Foster said. "He mentions a plain; and it must lie on a continent to the east——"
"If you assume that he sailed from Europe to America, then the continent to the east would be Europe," I said. "But maybe he went from Africa to South America, or——"

"You seem to know a little history, Foster," I said. "You've got a lot of odd facts tucked away."
"We need maps," Foster said. "We'll look for a plain near the sea——"
"Not necessarily."
"——and with a formation called a chalk face to the east."
"What's this 'median line' business?" I said. "And the bit about ten thousand parts of something?"
"I don't know. But we must have maps."
"I bought some this afternoon," I said. "I also got a dime-store globe. I figured we might need them. Let's get out of this and back to the room, where we can spread out. I know it's a grim prospect, but...." I got to my feet, dropped some coins on the oilcloth-covered table, and led the way out.
