were alert and active, anxious
that the work should go well, and fiercely irritable with whatever, by
delay or confusion, retarded that work. The toil of the traces seemed
the supreme expression of their being, and all that they lived for and
the only thing in which they took delight.

Dave was wheeler or sled dog, pulling in front of him was Buck, then
came Sol-leks; the rest of the team was strung out ahead, single file,
to the leader, which position was filled by Spitz.

Buck had been purposely placed between Dave and Sol-leks so that he
might receive instruction. Apt scholar that he was, they were equally
apt teachers, never allowing him to linger long in error, and enforcing
their teaching with their sharp teeth. Dave was fair and very wise. He
never nipped Buck without cause, and he never failed to nip him when he
stood in need of it. As Francois's whip backed him up, Buck found it
to be cheaper to mend his ways than to retaliate. Once, during a brief
halt, when he got tangled in the traces and delayed the start, both
Dave and Solleks flew at him and administered a sound trouncing. The
resulting tangle was even worse, but Buck took good care to keep the
traces clear thereafter; and ere the day was done, so well had he
mastered his work, his mates about ceased nagging him. Francois's whip
snapped less frequently, and Perrault even honored Buck by lifting up
his feet and carefully examining them.

It was a hard day's run, up the Canon, through Sheep Camp, past the
Scales and the timber line, across glaciers and snowdrifts hundreds of
feet deep, and over the great Chilcoot Divide, which stands between
the salt water and the fresh and guards forbiddingly the sad and lonely
North. They made good time down the chain of lakes which fills the
craters of extinct volcanoes, and late that night pulled into the huge
camp at the head of Lake Bennett, where thousands of goldseekers were
building boats against the break-up of the ice in the spring. Buck made
his hole in the snow and slept the sleep of the exhausted just, but all
too early was routed out in the cold darkness and harnessed with his
mates to the sled.

That day they made forty miles, the trail being packed; but the next
day, and for many days to follow, they broke their own trail, worked
harder, and made poorer time. As a rule, Perrault travelled ahead of
the team, packing the snow with webbed shoes to make it easier for them.
