"We'll tell Doctor Luke——"
"Yes; but what if Doctor Luke isn't back in the morning?"
"We'll go ourselves."
Archie started.
"Go?" he inquired, blankly. "Go where? We don't know where this letter came from. It isn't signed."
"Ah, well," said Billy, "somebody in Bread-and-Butter will know. Let's turn in, Archie. If we're t' take the trail the morrow, we must have rest."
And they turned in.
