s, and beating
the track became an exhausting labour.

But difficulties cannot finally stop, though they may retard, a
"Nor'-wester." On the sixth day, however, they met with a foe who had
power to lay a temporary check on their advance. On the night of the
fifth day out, another change of temperature took place. A thermometer,
had they carried one, would probably have registered from ten to twenty
below zero of Fahrenheit. This, however, was so familiar to them that
they rather liked the change, and heaped up fresh logs on the roaring
fire to counteract the cold; but when a breeze sprang up and began to
blow hard, they did not enjoy it so much, and when the breeze increased
to a gale, it became serious; for one cannot face intense cold during a
gale without the risk of being frost-bitten. In the shelter of the
woods it was all right, but when, towards noon, they came out on an
extended plain where the wild winds were whirling the wilder snow in
blinding drifts, they halted and looked inquiringly at each other.

"Shall we try it?" asked Macnab.

The Indian shook his head and looked solemn.

"It's a pity to give in without--"

A snow-drift caught the Highlander full in the mouth and literally shut
him up! The effect was not to subdue, but to arouse.

"Yes," he said in a species of calm ferocity, when the gale allowed him
the power of utterance, "we'll go on."

He went on, followed by the obedient native and the unhappy dogs, but he
had not taken half a dozen steps when he tripped over a concealed rock
and broke a snow-shoe. To walk with a broken snow-shoe is impossible.
To repair one is somewhat difficult and takes time. They were
compelled, therefore, to re-enter the sheltering woods and encamp.

"You're better at mending than I am," said Macnab to the Indian. "Set
to work on the shoe when the camp is dug out, an' I'll go cut some
firewood."

Cutting firewood is not only laborious, but attended with danger, and
that day ill-fortune seemed to have beset the Highlander; for he had
barely cut half a dozen logs, when his axe glanced off a knot and struck
deep into the calf of his left leg.

A shout brought Big Otter to his side. The Indian was well used to such
accidents. He bound up the wound securely, and carried his comrade into
camp on his back. But now Macnab was helpless. He not only could not
walk, but there was no hope of his being able to do so for weeks to
come.

"Lucky for us we brought
