We'll meet 'em and there'll be real trouble. We don't want their car,
anyway."

"Let's walk on an' catch Apple, then," suggested Chick-chick. "When he
finds we don't come he'll either wait for us or start back. We can all
ride into camp on the bike, we can."

"Leave the wagon just like this?"

"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."

"He said he kept it on the shelf with his railroad guides. I'm afraid he
put it in his pocket after they'd looked at it."

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?"

"That isn't saying it's so," objected Glen.

"It's sayin' it's worth lookin'," affirmed Chick-chick. "Didn't one of
'em say chart was drawn from description Indians gave?"

"Yes, but they might have been fooling 'em."

"An' they might not. If it's Indian cave it's got our treasure. You
draw copy that chart from memory soon as we get back, you do."

"I can't draw," objected Glen. "Maybe I can remember enough about it to
tell you or Apple how to put it on paper."

"Here's Apple coming now," said Chick-chick. "He's the boy to draw.
Draws better 'n flax seed poultice. You'll draw him all maps he wants
when we get to camp, won't ye, Apple?"

"If we ever get back," said Apple. "It's getting dark. Father will be
anxious. Why are you leaving the car?"
