"Twelve feet if it's an inch," murmured Leslie. "She took it splendidly, but all the same I don't want to have to repeat the experiment."

Fortunately, although there were other cracks in the ice, there were no obstacles of such size as the one they had just overcome, and without further incident the sleigh came to a standstill within twenty feet of the ship.

"What has happened?" asked Ranworth anxiously, as he caught sight of Aubrey Hawke's unconscious form.

Briefly Leslie related what had taken place.

"Hawke showed an error of judgment in not keeping his rifle loaded," commented Ranworth. "Of course, we are all apt to do that, but in his case it was most unfortunate. Goodness only knows what will happen as regards the electric sleigh. Our chief asset is now practically useless. But it is no use worrying. What is done cannot be undone."

"I brought this sleigh back, sir," began Leslie, then, self-conscious at his spontaneous boast, he stopped.

"Yes, you did remarkably well, my lad," agreed Ranworth.

"Then couldn't I have a shot at the big sleigh?" continued Leslie. "I understand the mechanism, and from what Mr. Hawke has told me the steering is very similar to that of the one I have just brought back. I'll do my level best, sir; and Guy will lend me a hand."

Ranworth paused before replying. He had already proof of Leslie's courage; he knew that the lad had a better knowledge of the giant sleigh than any other member of the expedition, Aubrey Hawke excepted. Since Aubrey Hawke was crippled with a broken arm, and suffering from shock, it was doubtful whether he would again be able to take an active part in the expedition.

Yet, Ranworth reflected, Leslie Ward was but a lad. It seemed too risky to entrust him with the important mission of piloting the electric sleigh to the aid of the sorely-pressed explorers.
