ns were expert in making camp, and soon the dogs were tethered
off to one side, and were snarling and snapping over their supper of
frozen seal blubber. After that they burrowed down under the snow to
keep warm.

"I guess we're in for a cold spell," remarked Mr. Baxter as he looked at
the thermometer he had hung outside the tent. "It's forty-one below now,
but the wind doesn't blow, and that makes it better. With a stiff gale
now we'd be in a bad way."

"Is it liable to get any colder?" asked Fred.

"It's liable to, but I hope it doesn't. This is all I want."

There was nothing to do but to go to bed, which they were glad enough to
do, as they would be warm in the sleeping bags. Seeing that the tent was
securely fastened, and that their rifles were ready at hand, Mr. Baxter
turned in. The boys were already asleep, for cold has the effect of
making one drowsy.

It was long after midnight when Fred was awakened by a series of loud
howls outside the tent. At the same time Mr. Baxter and Jerry sat up.

"What's that?" asked Fred.

"The dogs must have gotten loose and want something to eat," said Jerry.

we're going to have trouble. The animals are probably wild with hunger,
and have gotten scent of our camp."

CHAPTER XI

SHOOTING A MOOSE

It was the work of but an instant for the travelers to slip on their big
fur coats, and they were ready to go outside, for going to bed in the
arctic regions is more a process of dressing than undressing, and they
had lain down with even more clothes on than they wore during the day.

Mr. Baxter, kicking his sleeping bag to one side, loosed the fastenings
of the tent and stepped out. He was followed by Fred and Jerry, Johnson
coming last.

Fred was not prepared for the wonderful sight that met his gaze. At
first he thought he had been transported back to his own home, and that
a Fourth of July celebration was in progress. The sky was streaked with
long streamers of colored fire that waved and undulated to and fro,
beginning at the horizon and extending to the zenith.

"The Northern Lights!" exclaimed Mr. Baxter.

Then Fred understood that he had looked for the first time on the
wondrous and beautiful Aurora Borealis.

Suddenly the peacefulness of the night was once more broken by the
