The Jap girl smiled again as she took the jerkstrap from his hand and tied it down short to her own sled.  Then she leaped upon her sled again and, with some cooing words spoke to her reindeer.  The deer tossed his antlers and trotted quietly away, leaving Johnny to spring upon his own sled and ride in increasing wonderment over the long glistening miles.

When they had traveled for eight hours without a pause and without a balk, the Jap girl allowed her deer to stop.  She loosened the draw strap and, turning the animal about, tied him by a long line to the sled, that he might paw moss from beneath the snow in a wide circle.

“How—­how’d you know how to drive?” Johnny stammered.

“Never before so,” she smiled.

“You mean you never drove a reindeer?”

“Before now, no.  Hungry you?” The Jap girl smiled, as if to say, “Enough about that, let’s eat.”

It was a royal meal they ate together, those two there beneath the Arctic moon.  This Jap girl was a wonder, Johnny felt that, and he was to learn it more certainly as the days passed.

Three days later he sat upon a robe of deer skin.  The corners of the robe were drawn up over his shoulders.  A shelter of deer skins and walrus skins, hastily improvised by him during the beginning of a terrible blizzard which came howling down from the north, was ample to keep the wind from driving the biting snow into their faces, but it could hardly keep out the cold.  In spite of that, the Jap girl, buried in deer skins, with her back against his, was sleeping soundly.  Johnny was sleeping bolt upright with one ear awake.  His reindeer were picketed close to the improvised igloo.  Other nights, they had taken turns watching to protect them from prowling wolves, but this night no one could long withstand the numbing cold of the blizzard.  So he watched and half slept.  Now he caught the rising howl of the wind, and now felt its lull as the deer skins sagged.  But what was this?  Was there a different note, a howl that was not of the wind?

Shaking himself into entire wakefulness, Johnny sat bolt upright and listened intently.  Yes, there it was again.  A wolf beyond doubt, as yet some distance away, but coming toward them with the wind.

A wolf, a single one, was not all menace.  If he could be shot before his fangs tore at the flesh of a reindeer, there would be gain.  He would be food, and at the present moment there was no food.  The Jap girl did not know it, but Johnny did.  Not a fish, not a hunk of venison, not a pilot biscuit was on their sled.  They would soon be reduced to the necessity of killing and eating one of their deer, unless, unless—­the howl came more plainly and strangely enough with it came the crack crack of hoofs.

Johnny sprang to his feet.  What could that crack cracking of hoofs mean?  Had one of his deer already broken his tether?

With automatic in hand, he was out in the storm in an instant.  Even as he became accustomed to the dim light, he saw a skulking form drifting down with the wind.  Dropping upon his stomach, he took deliberate aim and fired.  There was a howl of agony but still the creature came on.  Another shot and it turned over tearing at the whirling snow.
