"Why not? 'Tain't ours: All we've done is interfere with burglars. If this car carries the burgling things to rob the bank they won't be able to burgle to-night, anyway. Let's look for that chart they showed you. If it's anything about the treasure it's ours."

They found the shelf with the railroad folders, but no chart of any description was there.

"'Fraid you'd see more of it than they wanted," suggested Chick-chick.

"They need not," said Glen. "I don't care what's on their chart."

"Why not?" asked Chick-chick. "Why not? They got chart cave. Cave is somewhere between our camp an' top Buffalo Mound. They say Indian cave an' think Indians have hid treasure there; why not?"

"What makes you think the cave is between our camp and the top of Buffalo Mound?"

"Didn't you say Jervice man stuck his thumb over—so shut out your look. What he do that for if cave ain't there?"

"You jump too quick, Chick-chick. I'm not sure there's a cave at all. I just know that they talked as if they were looking for a cave or a hole in the ground or some place where somebody had hid a lot of plunder."

"Sure you know it. An' why wouldn't it be a cave? An' didn't you say the big man said he'd bet Indians had bullion hid in same cave they were hunting. Didn't you?"
