"I'm afraid the coyote is going to be a drag on us, much as I should like to take him along," said Tad.

Stacy begged to keep the animal, and Tad decided to try it. The next question was, how to move it. It was finally decided that one boy should lead the coyote while the other prodded it from the rear when the animal lagged.

At noon they halted to rest, draining the last drop from their canteens. Then they started on again, suffering more and more from the heat as they proceeded. About the middle of the afternoon Tad halted, gazing helplessly about him.

"Chunky, we're lost in the Desert Maze. I don't know where I am any more than if I were in the middle of an ocean. I'm pretty nearly exhausted, too."

"So's the coyote," comforted Stacy.

"But we've got to keep on going. My watch is missing. I must have lost it where we slept last night. I can only guess at the direction we ought to take. Have you any idea where we are?"

Stacy gazed at the sky meditatively.

"On a rough guess, I should say we were on the Nevada Desert."

"Oh, come on! Come on!"

Still clinging to the angry coyote, the lads took up their weary tramp. The baking alkali burned their feet almost to the blistering point; the burning, withering heat made their heads whirl; the desert began to perform strange antics, while the halo that they had seen a few days before again appeared before them, first whirling like a giant pin wheel, then oscillating in a way that made them giddy.
