“I don’t think so—unless you fellows roll down some stones on me.”

“We’ll be careful about that,” answered Ben; and lost no time in pushing back a number of stones which lay close to the brink of the opening.

“We’ll have to get a rope or something with which to haul him up,” said Phil. “Dave, did we bring anything of that sort along?”

“Yes, I’ve got a good strong lariat tied to my saddle,” answered our hero. “Frank Andrews advised taking it along; for when you are traveling among the mountains you can never tell when you’ll need such a rope. I’ll go back and get it.”

“Maybe you’d better bring a few straps along, too, Dave,” put in Roger. “Then, if Shadow can’t haul himself up, he can tie himself fast and we can pull him up.”

“Good idea, Roger. I’ll do it.”

Dave was soon on his way, and in less than twenty minutes he was back to the spot, carrying the lariat he had mentioned and also a number of straps taken from the outfit. The lariat was of rawhide, and more than once had been tested by the civil engineers for its strength. It had been purchased by Andrews from a cowboy in Texas, after the latter had given a very fine exhibition of lassoing steers with it.

“We’re sending down the end of a lariat with some straps,” called down Dave. “Let us know as soon as it is low enough.”

“All right,” answered Shadow, but somewhat feebly, for the tumble had evidently knocked the breath out of him.

Tying the loose straps to the end of the rope, and weighting the whole down with a stone, Dave lowered the lariat carefully over the edge of the opening. It slipped through his hands readily, and soon the end disappeared from sight over a bulge of the wall below. All of the others watched the rope as it disappeared into the opening. They waited for some cry from Shadow, stating that he had hold of the other end, but none came.
