There followed an animated discussion evidently with reference to the load on the sleigh. Petrovitch and two more seemed to be opposing the taking of so much luggage, but the rest insisted vehemently. Finally, the objectors lost the day.
With a meaning shrug of his broad shoulders, Petrovitch turned to Leslie.
"Wait till they arrive at the crevasse," he said in a low tone.
It was downhill most of the way, and since there was no wind to impede them, the progress of the rescued party was well maintained. With relays of five men to pull the sleigh, that vehicle offered no drawback to their speed.
Suddenly, when they were within a quarter of a mile of the ice bridge, a rending crash was heard, and amid a shower of splintered ice a huge cavity appeared where a second previously an uninterrupted field of frozen snow hid the terrible chasm from view.
The newly-made hole was less than a hundred yards from the track by which Leslie and Petrovitch had passed. Undoubtedly the falling in of this part of the ice-bridge would seriously weaken the already none too secure route which had to be traversed before the Bird of Freedom was reached.
Leslie took no part in the operations that followed. He realised that the Russians knew what they were about, and that it would be unwise on his part to offer any suggestions.
Unloading the coils of rope from the sleigh, the men bent them to the rope which had already played such a good part in the previous crossing of the crevasse. The three lengths combined were sufficient to allow a double rope to stretch from one side to the other.
Securing the rope to the strongest part of the sleigh, Petrovitch prepared to cross. The 18-feet runners enabled his weight to be evenly distributed over a far greater extent than if he had adopted his previous expedient of crawling across the ice-bridge.
Having thrown overboard everything on the sleigh, the Russian wrenched off the centre strip of boarding on the floor. Then, sitting, he started to propel the sleigh across the ice, while his comrades paid out the rope as he went.
