"None of that," Chase cut in. "Take it or leave it. If you haven't got the grit, Sutton of the Flashlight will jump at the chance."

He held the contents bill up to the light again and Grady nodded. He was going to do this thing deliberately, once he was sure of his ground. He remarked cynically that it sounded like a fairy story.

They just lose their vessel and strike for the nearest land. Knowing something of our quarantine laws they make themselves scarce as soon as they can. A local doctor calls the plague English cholera, too much bad fruit in very hot weather, and there you are."

Grady nodded again. The sweltering heat of the place no longer affected him. Down below the presses were already beginning to clang and boom. There was a constant clatter of feet along the passages.

"Sit down right away," Grady snapped. "Make two columns of it. I'll get some statistics out for you."

Chase peeled off his coat and got to work at once. Grady found the book he required and proceeded to compile his facts therefrom.
