"We will yet live," Smoke comforted her. "Hereafter he shall carry the flour. He can't eat that raw, and if he does I'll kill him myself, for he will be eating your life as well as mine." He held her closer.

"Sweetheart, killing is men's work. Women do not kill."

"You would not love me if I killed the dog?" she questioned in surprise.

"Not so much," Smoke temporized.

She sighed with resignation. "Very well," she said. "I shall not kill him."

The pursuit by the young men was relentless. By miracles of luck, as well as by deduction from the topography of the way the runaways must take, the young men picked up the blizzard-blinded trail and clung to it. When the snow flew, Smoke and Labiskwee took the most improbable courses, turning east when the better way opened south or west, rejecting a low divide to climb a higher. Being lost, it did not matter.

Yet they could not throw the young men off. Sometimes they gained days, but always the young men appeared again. After a storm, when all trace was lost, they would cast out like a pack of hounds, and he who caught the later trace made smoke signals to call his comrades on.

Smoke lost count of time, of days and nights and storms and camps.

Through a vast mad phantasmagoria of suffering and toil he and Labiskwee struggled on, with McCan somehow stumbling along in the rear, babbling of San Francisco, his everlasting dream. Great peaks, pitiless and serene in the chill blue, towered about them. They fled down black canyons with walls so precipitous that the rock frowned naked, or wallowed across glacial valleys where frozen lakes lay far beneath their feet. And one night, between two storms, a distant volcano glared the sky. They never saw it again, and wondered whether it had been a dream.

Crusts were covered with yards of new snow, that crusted and were snow-covered again. There were places, in canyon- and pocket-drifts, where they crossed snow hundreds of feet deep, and they crossed tiny glaciers, in drafty rifts, wind-scurried and bare of any snow. They crept like silent wraiths across the faces of impending avalanches, or roused from exhausted sleep to the thunder of them. They made fireless camps above timber-line, thawing their meat-rations with the heat of their bodies ere they could eat. And through it all Labiskwee remained Labiskwee. Her cheer never vanished, save when she looked at McCan, and the greatest stupor of fatigue and cold never stilled the eloquence of her love for Smoke.

Like a cat she watched the apportionment of the meager ration, and Smoke could see that she grudged McCan every munch of his jaws. Once, she distributed the ration. The first Smoke knew was a wild harangue of protest from McCan. Not to him alone, but to herself, had she given a smaller portion than to Smoke. After that, Smoke divided the meat himself. Caught in a small avalanche one morning after a night of snow, and swept a hundred yards down the mountain, they emerged half-stifled and unhurt, but McCan emerged without his pack in which was all the flour. A second and larger snow-slide buried it beyond hope of recovery.

After that, though the disaster had been through no fault of his, Labiskwee never looked at McCan, and Smoke knew it was because she dared not.

It was a morning, stark still, clear blue above, with white sun-dazzle on the snow. The way led up a long, wide slope of crust. They moved like weary ghosts in a dead world. No wind stirred in the stagnant, frigid calm. Far peaks, a hundred miles away, studding the backbone of the Rockies up and down, were as distinct as if no more than five miles away.

"Something is going to happen," Labiskwee whispered. "Don't you feel it?--here, there, everywhere? Everything is strange."

"I feel a chill that is not of cold," Smoke answered. "Nor is it of hunger."

"It is in your head, your heart," she agreed excitedly. "That is the way I feel it."

"It is not of my senses," Smoke diagnosed. "I sense something, from without, that is tingling me with ice; it is a chill of my nerves."

A quarter of an hour later they paused for breath.

"I can no longer see the far peaks," Smoke said.

"The air is getting thick and heavy," said Labiskwee. "It is hard to breathe."

"There be three suns," McCan muttered hoa.r.s.ely, reeling as he clung to his staff for support.

There was a mock sun on either side of the real sun.

"There are five," said Labiskwee; and as they looked, new suns formed and flashed before their eyes.

"By Heaven, the sky is filled with suns beyant all countin'," McCan cried in fear.

Which was true, for look where they would, half the circle of the sky dazzled and blazed with new suns forming.

McCan yelped sharply with surprise and pain. "I'm stung!" he cried out, then yelped again.

Then Labiskwee cried out, and Smoke felt a p.r.i.c.kling stab on his cheek so cold that it burned like acid. It reminded him of swimming in the salt sea and being stung by the poisonous filaments of Portuguese men-of-war. The sensations were so similar that he automatically brushed his cheek to rid it of the stinging substance that was not there.

And then a shot rang out, strangely m.u.f.fled. Down the slope were the young men, standing on their skees, and one after another opened fire.

"Spread out!" Smoke commanded. "And climb for it! We're almost to the top. They're a quarter of a mile below, and that means a couple of miles the start of them on the down-going of the other side."

With faces p.r.i.c.kling and stinging from invisible atmospheric stabs, the three scattered widely on the snow surface and toiled upward. The m.u.f.fled reports of the rifles were weird to their ears.

"Thank the Lord," Smoke panted to Labiskwee, "that four of them are muskets, and only one a Winchester. Besides, all these suns spoil their aim. They are fooled. They haven't come within a hundred feet of us."

"It shows my father's temper," she said. "They have orders to kill."

"How strange you talk," Smoke said. "Your voice sounds far away."

"Cover your mouth," Labiskwee cried suddenly. "And do not talk. I know what it is. Cover your mouth with your sleeve, thus, and do not talk."

McCan fell first, and struggled wearily to his feet. And after that all fell repeatedly ere they reached the summit. Their wills exceeded their muscles, they knew not why, save that their bodies were oppressed by a numbness and heaviness of movement. From the crest, looking back, they saw the young men stumbling and falling on the upward climb.

"They will never get here," Labiskwee said. "It is the white death. I know it, though I have never seen it. I have heard the old men talk.

Soon will come a mist--unlike any mist or fog or frost-smoke you ever saw. Few have seen it and lived."

McCan gasped and strangled.

"Keep your mouth covered," Smoke commanded.

A pervasive flashing of light from all about them drew Smoke's eyes upward to the many suns. They were shimmering and veiling. The air was filled with microscopic fire-glints. The near peaks were being blotted out by the weird mist; the young men, resolutely struggling nearer, were being engulfed in it. McCan had sunk down, squatting, on his skees, his mouth and eyes covered by his arms.

"Come on, make a start," Smoke ordered.

"I can't move," McCan moaned.

His doubled body set up a swaying motion. Smoke went toward him slowly, scarcely able to will movement through the lethargy that weighed his flesh. He noted that his brain was clear. It was only the body that was afflicted.

"Let him be," Labiskwee muttered harshly.

But Smoke persisted, dragging the Irishman to his feet and facing him down the long slope they must go. Then he started him with a shove, and McCan, braking and steering with his staff, shot into the sheen of diamond-dust and disappeared.

Smoke looked at Labiskwee, who smiled, though it was all she could do to keep from sinking down. He nodded for her to push off, but she came near to him, and side by side, a dozen feet apart, they flew down through the stinging thickness of cold fire.

Brake as he would, Smoke's heavier body carried him past her, and he dashed on alone, a long way, at tremendous speed that did not slacken till he came out on a level, crusted plateau. Here he braked till Labiskwee overtook him, and they went on, again side by side, with diminishing speed which finally ceased. The lethargy had grown more p.r.o.nounced. The wildest effort of will could move them no more than at a snail's pace. They pa.s.sed McCan, again crouched down on his skees, and Smoke roused him with his staff in pa.s.sing.

"Now we must stop," Labiskwee whispered painfully, "or we will die. We must cover up--so the old men said."

She did not delay to untie knots, but began cutting her pack-lashings.

Smoke cut his, and, with a last look at the fiery death-mist and the mockery of suns, they covered themselves over with the sleeping-furs and crouched in each other's arms. They felt a body stumble over them and fall, then heard feeble whimpering and blaspheming drowned in a violent coughing fit, and knew it was McCan who huddled against them as he wrapped his robe about him.

Their own lung-strangling began, and they were racked and torn by a dry cough, spasmodic and uncontrollable. Smoke noted his temperature rising in a fever, and Labiskwee suffered similarly. Hour after hour the coughing spells increased in frequency and violence, and not till late afternoon was the worst reached. After that the mend came slowly, and between spells they dozed in exhaustion.

McCan, however, steadily coughed worse, and from his groans and howls they knew he was in delirium. Once, Smoke made as if to throw the robes back, but Labiskwee clung to him tightly.

"No," she begged. "It is death to uncover now. Bury your face here, against my parka, and breathe gently and do no talking--see, the way I am doing."
