rain; if it don't draw then, ye raise the bottom of the cover under
the door just a little--that always fetches her. An' when you change

his high-water mark of affluence, and this he had reached but once in
his life.

"Oh, I dunno'; that depends," was Sam's more guarded response.

"Can _you_ do it?" asked Yan.
