"Well?" he asked.
"S. L. stand for Silas Lakewood, don't they?" Bob asked a bit impatiently.
"They could, of course, but don't forget that they could also stand for a good many other names as well. It doesn't look to me as though those letters were cut there very recently. What do you say, Lucky?"
The Indian looked at the letters for a long time before he made any reply, but he finally turned to Jack and said:
"Heap hard tell, but Injun tink them not ver' old, mebby three, mebby four week."
"Why do you think so?" Bob asked.
"Color wood tell Injun."
"Well, I think it's a pretty safe bet that he's been here anyhow," Bob declared.
"But we knew that before," Jack said. "Or at least we have that man's word for it."
"Yes and these letters make it pretty near certain, don't you think, Lucky?"
