their grub supply was gone. The huskies had chewed through the
sled lashings and canvas coverings. In fact, nothing, no matter
how remotely eatable, had escaped them. They had eaten a pair of
Perrault's moose-hide moccasins, chunks out of the leather traces,
and even two feet of lash from the end of Francois's whip. He

team was under way, struggling painfully over the hardest part of

The Thirty Mile River was wide open. Its wild water defied the
frost, and it was in the eddies only and in the quiet places that

a cold snap was on, the thermometer registering fifty below zero,
and each time he broke through he was compelled for very life to
