Two hours later, Guy, who had relieved Ranworth at the steering wheel, reported a ridge of hills ahead, pierced by two narrow passes.

"Which one shall I make for, sir?" he asked, Ranworth having rejoined him.

"I don't think it matters much," was the reply. "Both diverge equally on either side of our current compass course. Take the right hand one for choice. Ease her down, Leslie, when we approach the defile. We don't want to barge into anything if we can help it."

Contrary to Ranworth's expectations, the passage through the line of hills was a fairly easy one. There were evidences of heavy falls of snow and débris from the cliffs on either hand, but the centre of the pass was almost unimpeded.

"What's that, sir?" asked Guy, as the sleigh rounded a gentle curve.

Projecting from a hole in the cliffs, was the largest animal the lad had ever seen. It resembled an elephant, yet in place of short hair it was covered with long whitish grey fur. The trunk was extended, and on either side was a curved tusk fully fifteen feet in length.

"Make straight for it," ordered Ranworth.

Guy obeyed, wondering what his companion intended doing. The sleigh, strong of build and powerfully engined, was not a fit object with which to ram a gigantic beast such as this.

"Near enough," directed Ranworth. "It's a pity we can't stop and examine the thing more closely. There's a fortune in those tusks."

"I thought it was alive, sir," said Guy.
