physical pain that gave the sullen droop to his head and robbed his body
of that keen quick alertness of the lead-dog--the commander of his
mates. It was his spirit. For the first time in his life, it was broken.
McCready had beaten him--long ago; his master had beaten him; and
during all this day their voices were fierce and vengeful in his ears.
But it was his mistress who hurt him most. She held aloof from him,
always beyond they reach of his leash; and when they stopped to rest,
and again in camp, she looked at him with strange and wondering eyes,

Then he went out into the gloom and bent low over the trail they had
made a few hours before. It was almost obliterated by the falling snow.
Another hour and there would be no trail--nothing the next day to tell
whoever might pass that they had come this way. By morning it would
