a
bunch of keys. He inserted his hand and drew out a heavy Colt's
revolver. Next came out a few boxes of ammunition for the revolver and
several boxes of Winchester cartridges.

Churchill took the gripsack and looked into it. Then he turned it upside
down and shook it gently.

"The gun's all rusted," Bondell said. "Must have been out in the rain."

"Yes," Churchill answered. "Too bad it got wet. I guess I was a bit
careless."

He got up and went outside. Ten minutes later Louis Bondell went out and
found him on the steps, sitting down, elbows on knees and chin on hands,
gazing steadfastly out into the darkness.

TO BUILD A FIRE

Day had broken cold and grey, exceedingly cold and grey, when the man
turned aside from the main Yukon trail and climbed the high earth-bank,
where a dim and little-travelled trail led eastward through the fat
spruce timberland. It was a steep bank, and he paused for breath at the
top, excusing the act to himself by looking at his watch. It was nine
o'clock. There was no sun nor hint of sun, though there was not a cloud
in the sky. It was a clear day, and yet there seemed an intangible pall
over the face of things, a subtle gloom that made the day dark, and that
was due to the absence of sun. This fact did not worry the man. He was
used to the lack of sun. It had been days since he had seen the sun, and
he knew that a few more days must pass before that cheerful orb, due
south, would just peep above the sky-line and dip immediately from view.

The man flung a look back along the way he had come. The Yukon lay a
mile wide and hidden under three feet of ice. On top of this ice were as
many feet of snow. It was all pure white, rolling in gentle undulations
where the ice-jams of the freeze-up had formed. North and south, as far
as his eye could see, it was unbroken white, save for a dark hair-line
that curved and twisted from around the spruce-covered island to the
south, and that curved and twisted away into the north, where it
disappeared behind another spruce-covered island. This dark hair-line
was the trail--the main trail--that led south five hundred miles to the
Chilcoot Pass, Dyea, and salt water; and that led north seventy miles to
Dawson, and still on to the north a thousand miles to Nulato, and finally
to St. Michael on Bering Sea, a thousand miles and half a thousand more.

But all this--the mysterious, far-reaching hairline trail, the absence of
sun f
