Will looked up at the steep and lofty slopes on either side. The one on the right seemed less steep and lofty than the other, and upon it hung a short growth of pine and cedar, characteristic of the region. His spirit, which danger had made bold and venturesome, seized upon an idea.

"Why not go up the slope on the right?" he asked.

"It's like the side of a house, only many times as high," said Boyd in amazement.

"But it isn't," said the lad. "It merely looks so in the dark. We can climb it."

"Of course we could, but we'd have to abandon the horses and mules and all our packs and stores, and then where would we be?"

"But we won't have to leave 'em. They can climb too. You know how you boasted of our horses, and the Giant's horses are mules which can go anywhere."

"I believe the boy's right," said the Little Giant. "By our pullin' on the lariats an' thar takin' advantage o' ev'ry footgrip, they might do it. Leastways we kin try it."

"It's a desperate chance," said the hunter, "but I think with you, Tom, that it's worth trying. Now, boys, make fast the packs to the last strap, and up we go."

"Bein' as my hosses are mules," said the Little Giant, "I'll lead the way, an' you foller, each feller pullin' on two lariats."

He started up the slope, whistling gayly but low to his mules, and, after some hesitation, they attacked the ascent, Tom still whistling to them in his most cheerful and engaging manner. There was a sound of scrambling feet, and small stones rolled down, but not the mules, which disappeared from sight among the cedars.
