"Thirsty!" The former could barely speak.

"There won't be any water till we get across. You'll have to stand it."

They resumed their duties; the Indian "swish-swished" ahead, as if wading through a sea of swan's-down; the dogs followed listlessly; the partners leaned against the stubborn load.

A faint breath finally came out of the north, causing Grant and the guide to study the sky anxiously. Cantwell was too weary to heed the increasing cold. The snow on the slopes above began to move; here and there, on exposed ridges, it rose in clouds and puffs; the cleancut outlines of the hills became obscured as by a fog; the languid wind bit cruelly.

After a time Johnny fell back upon the sled and exclaimed: "I'm—all in, Mort. Don't seem to have the—guts." He was pale, his eyes were tortured. He scooped a mitten full of snow and raised it to his lips, then spat it out, still dry.

"Here! Brace up!" In a panic of apprehension at this collapse Grant shook him; he had never known Johnny to fail like this. "Take a drink; it'll do you good." He drew a bottle from one of the dunnage bags and Cantwell seized it avidly. It was wet; it would quench his thirst, he thought. Before Mort could check him he had drunk a third of the contents.

The effect was almost instantaneous, for Cantwell's stomach was empty and his tissues seemed to absorb the liquor like a dry sponge; his fatigue fell away, he became suddenly strong and vigorous again. But before he had gone a hundred yards the reaction followed. First his mind grew thick, then his limbs became unmanageable and his muscles flabby. He was drunk. Yet it was a strange and dangerous intoxication, against which he struggled desperately. He fought it for perhaps a quarter of a mile before it mastered him; then he gave up.

Both men knew that stimulants are never taken on the trail, but they had never stopped to reason why, and even now they did not attribute Johnny's breakdown to the brandy. After a while he stumbled and fell, then, the cool snow being grateful to his face, he sprawled there motionless until Mort dragged him to the sled. He stared at his partner in perplexity and laughed foolishly. The wind was increasing, darkness was near, they had not yet reached the Bering slope.

Something in the drunken man's face frightened Grant and, extracting a ship's biscuit from the grub box, he said, hurriedly: "Here, Johnny. Get something under your belt, quick."

Cantwell obediently munched the hard cracker, but there was no moisture on his tongue; his throat was paralyzed; the crumbs crowded themselves from the corners of his lips. He tried with limber fingers to stuff them down, or to assist the muscular action of swallowing, but finally expelled them in a cloud. Mort drew the parka hood over his partner's head, for the wind cut like a scythe and the dogs were turning tail to it, digging holes in the snow for protection. The air about them was like yeast; the light was fading.
