An hour later she was passing through the defile in which the mammoth had been discovered. The strong wind had set a considerable portion of the landslide into further motion, with the result that the general slope of the debris was more gradual, while the gigantic frozen mammoth was uncovered as far as the forequarters.

"We'll have those tusks," reiterated Ranworth, "even if we have to make a third journey for them. If, however, we find that the sleigh makes light of her load, we'll stop and get the things on board on the return journey."

Ranworth, of course, could take no manual part in the management of the sleigh. He had to be content to sit at one of the two foremost scuttles, while Guy and the four seamen took turns at the steering-wheel. Leslie, having satisfied himself that the motors were running well, was able to "stand easy," since there seemed no immediate necessity to check their speed.

In exactly four hours from the time of starting from the ship, the Bird of Freedom stopped at Observation Camp.

"All correct, sir," announced O'Donovan. "Faith, I'm far from being fed up with bear steaks yet. Sure, 'tis a fine place to cultivate an appetite. But what has happened to your arm, sir, if I may make so bold as to ax?"

Ranworth, as impatient as ever, was anxious to commence the return journey. The remaining members of the expedition were allowed to take their personal belongings. The Russians, having lost theirs, were soon ready.

One package only did Ranworth order to be brought into the cabin and the transporting of it was entrusted to Leslie and Guy. It was the lump of platinum, the value of which would more than cover twice the cost of the expedition.

By means of a rope made fast round the fur coverings, the lads dragged the precious metal to the side of the sleigh with little difficulty; but the task of lifting it up to the door in the side of the cabin was beyond them. Even when Symonds, the "strong man" of the party, bore a hand, the comparatively small package refused to be lifted from the ground.

"It's as heavy as lead," he growled.

"It so happens it's almost double the weight of an equal bulk of lead," remarked Leslie, "and it's ever so much more valuable than gold."
