“Don’t you be in too great a hurry, my lad. We’re going to have another good hunt round at the bottom of these great cliffs, and if that comes to nothing we might try smelling.”

“Ah! Nothing but a dog would be any use there.”

“In a hurry again, boy. I’d back something else to find water before a dog.”

“A fish on dry land?”

“Tchah! No. What was it found the lake for us the other day?”

“The mule,” cried Chris.

“Got it again,” said Griggs, laughing. “I don’t say he would, but I shouldn’t at all wonder, if we brought old Skeeter round, as like as not he’d smell out the place.”

“Buried under some of these great stone slides that have come down?”

“To be sure, my lad. Now, that’s a likely place.”

Griggs pointed to a huge gap in the cliff away to their right where the carved-out openings running along behind a rough terrace a hundred feet up the vast wall suddenly ceased as if broken off, and commenced again at about the same height on the other side of the gap.
