"Ho! Ho! when hell freezes over—if we must!"

Jones found one 45-90 cartridge in all the outfit, and with that in the chamber of his rifle, once more struck south. Spruce trees began to show on the barrens and caribou trails roused hope in the hearts of the hunters.

"Look in the spruces," whispered Jones, dropping the rope of his sled. Among the black trees gray objects moved.

"Caribou!" said Rea. "Hurry! Shoot! Don't miss!"

But Jones waited. He knew the value of the last bullet. He had a hunter's patience. When the caribou came out in an open space, Jones whistled. It was then the rifle grew set and fixed; it was then the red fire belched forth.

At four hundred yards the bullet took some fraction of time to strike. What a long time that was! Then both hunters heard the spiteful spat of the lead. The caribou fell, jumped up, ran down the slope, and fell again to rise no more.

An hour of rest, with fire and meat, changed the world to the hunters; still glistening, it yet had lost its bitter cold its deathlike clutch.

"What's this?" cried Jones.

Moccasin tracks of different sizes, all toeing north, arrested the hunters.

"Pointed north! Wonder what thet means?" Rea plodded on, doubtfully shaking his head.
