They had gone down the shelving and soft
side of the Gulch a hundred feet or more before either of them regained
his footing. The man with the scar, who was in advance of his companion,
first attempted to rise, but his effort was intercepted by his larger
companion who slid against him with full force, again sending both men
rolling down the cliff side.

Inasmuch as there was no special danger connected with their descent, for
the ground was soft, the amusement of the Go Ahead Boys became keen. They
laughed and shouted their words of approval, and Zeke's words were the
loudest of all.

The two men, when at last they succeeded in regaining an upright position,
turned and savagely shook their fists at the laughing party on the rim of
the Gulch and then resuming their descent, continued on their way until
both disappeared from sight.

"I'm thinkin'," said Zeke as the party returned to the camp, "that those
fellows won't come back here again, at least in the daytime."

"If they come at night," suggested Fred, "it won't do us any good, I'm
afraid."

"No more it won't," acknowledged the guide, "but if my plans work out,
when they come back here we shall be gone."

"Did you find Tom's Thumb?" asked Grant

"Did it really look like a thumb?" inquired Fred excitedly.

"It did. We both saw it about the same time and there wasn't any mistaking
it either."

"That's all right then," said Grant. "If we've found Two Crow Tree and
Tom's Thumb then it ought not to be very hard for us to find Split Rock.
We know just about where it is placed, according to the map that Simon
Moultrie drew."

"It's on the other side of the Gulch though," suggested George.

"You don't mean it?" exclaimed Fred laughingly. "What a wise chap you
are." As Fred spoke Grant drew from his pocket the paper on which he had
retraced the outlines of the map drawn by Simon Moultrie.

"In course we're not sure," said Zeke, "but we can get an idea about where
to look."

"When shall we start?" asked Grant.

"First thing in the morning" replied the guide. "We wouldn't take any
chances starting by night, though now tha
