It was a dead world, and furthermore, a gray world. The weather was sharp and clear; there was no moisture in the atmosphere, no fog nor haze; yet the sky was a gray pall. The reason for this was that, though there was no cloud in the sky to dim the brightness of day, there was no sun to give brightness. Far to the south the sun climbed steadily to meridian, but between it and the frozen Yukon intervened the bulge of the earth. The Yukon lay in a night shadow, and the day itself was in reality a long twilight-light. At a quarter before twelve, where a wide bend of the river gave a long vista south, the sun showed its upper rim above the sky-line. But it did not rise perpendicularly. Instead, it rose on a slant, so that by high noon it had barely lifted its lower rim clear of the horizon. It was a dim, wan sun. There was no heat to its rays, and a man could gaze squarely into the full orb of it without hurt to his eyes. No sooner had it reached meridian than it began its slant back beneath the horizon, and at quarter past twelve the earth threw its shadow again over the land.
The men and dogs raced on. Daylight and Kama were both savages so far as their stomachs were concerned. They could eat irregularly in time and quantity, gorging hugely on occasion, and on occasion going long stretches without eating at all. As for the dogs, they ate but once a day, and then rarely did they receive more than a pound each of dried fish. They were ravenously hungry and at the same time splendidly in condition. Like the wolves, their forebears, their nutritive processes were rigidly economical and perfect. There was no waste. The last least particle of what they consumed was transformed into energy.
And Kama and Daylight were like them. Descended themselves from the generations that had endured, they, too, endured. Theirs was the simple, elemental economy. A little food equipped them with prodigious energy. Nothing was lost. A man of soft civilization, sitting at a desk, would have grown lean and woe-begone on the fare that kept Kama and Daylight at the top-notch of physical efficiency. They knew, as the man at the desk never knows, what it is to be normally hungry all the time, so that they could eat any time. Their appetites were always with them and on edge, so that they bit voraciously into whatever offered and with an entire innocence of indigestion.
By three in the afternoon the long twilight faded into night. The stars came out, very near and sharp and bright, and by their light dogs and men still kept the trail. They were indefatigable. And this was no record run of a single day, but the first day of sixty such days. Though Daylight had passed a night without sleep, a night of dancing and carouse, it seemed to have left no effect. For this there were two explanations first, his remarkable vitality; and next, the fact that such nights were rare in his experience. Again enters the man at the desk, whose physical efficiency would be more hurt by a cup of coffee at bedtime than could Daylight's by a whole night long of strong drink and excitement.
Daylight travelled without a watch, feeling the passage of time and largely estimating it by subconscious processes. By what he considered must be six o'clock, he began looking for a camping-place. The trail, at a bend, plunged out across the river. Not having found a likely spot, they held on for the opposite bank a mile away. But midway they encountered an ice-jam which took an hour of heavy work to cross. At last Daylight glimpsed what he was looking for, a dead tree close by the bank. The sled was run in and up. Kama grunted with satisfaction, and the work of making camp was begun.
The division of labor was excellent. Each knew what he must do. With one ax Daylight chopped down the dead pine. Kama, with a snowshoe and the other ax, cleared away the two feet of snow above the Yukon ice and chopped a supply of ice for cooking purposes. A piece of dry birch bark started the fire, and Daylight went ahead with the cooking while the Indian unloaded the sled and fed the dogs their ration of dried fish. The food sacks he slung high in the trees beyond leaping-reach of the huskies. Next, he chopped down a young spruce tree and trimmed off the boughs. Close to the fire he trampled down the soft snow and covered the packed space with the boughs. On this flooring he tossed his own and Daylight's gear-bags, containing dry socks and underwear and their sleeping-robes. Kama, however, had two robes of rabbit skin to Daylight's one.
They worked on steadily, without speaking, losing no time. Each did whatever was needed, without thought of leaving to the other the least task that presented itself to hand. Thus, Kama saw when more ice was needed and went and got it, while a snowshoe, pushed over by the lunge of a dog, was stuck on end again by Daylight. While coffee was boiling, bacon frying, and flapjacks were being mixed, Daylight found time to put on a big pot of beans. Kama came back, sat down on the edge of the spruce boughs, and in the interval of waiting, mended harness.
"I t'ink dat Skookum and Booga make um plenty fight maybe," Kama remarked, as they sat down to eat.
"Keep an eye on them," was Daylight's answer.
And this was their sole conversation throughout the meal. Once, with a muttered imprecation, Kama leaped away, a stick of firewood in hand, and clubbed apart a tangle of fighting dogs. Daylight, between mouthfuls, fed chunks of ice into the tin pot, where it thawed into water. The meal finished, Kama replenished the fire, cut more wood for the morning, and returned to the spruce bough bed and his harness-mending. Daylight cut up generous chunks of bacon and dropped them in the pot of bubbling beans. The moccasins of both men were wet, and this in spite of the intense cold; so when there was no further need for them to leave the oasis of spruce boughs, they took off their moccasins and hung them on short sticks to dry before the fire, turning them about from time to time. When the beans were finally cooked, Daylight ran part of them into a bag of flour-sacking a foot and a half long and three inches in diameter. This he then laid on the snow to freeze. The remainder of the beans were left in the pot for breakfast.
It was past nine o'clock, and they were ready for bed. The squabbling and bickering among the dogs had long since died down, and the weary animals were curled in the snow, each with his feet and nose bunched together and covered by his wolf's brush of a tail. Kama spread his sleeping-furs and lighted his pipe. Daylight rolled a brown-paper cigarette, and the second conversation of the evening took place.
"I think we come near sixty miles," said Daylight.
"Um, I t'ink so," said Kama.
They rolled into their robes, all-standing, each with a woolen Mackinaw jacket on in place of the parkas[5] they had worn all day. Swiftly, almost on the instant they closed their eyes, they were asleep. The stars leaped and danced in the frosty air, and overhead the colored bars of the aurora borealis were shooting like great searchlights.
In the darkness Daylight awoke and roused Kama. Though the aurora still flamed, another day had begun. Warmed-over flapjacks, warmed-over beans, fried bacon, and coffee composed the breakfast. The dogs got nothing, though they watched with wistful mien from a distance, sitting up in the snow, their tails curled around their paws. Occasionally they lifted one fore paw or the other, with a restless movement, as if the frost tingled in their feet. It was bitter cold, at least sixty-five below zero, and when Kama harnessed the dogs with naked hands he was compelled several times to go over to the fire and warm the numbing finger-tips. Together the two men loaded and lashed the sled. They warmed their hands for the last time, pulled on their mittens, and mushed the dogs over the bank and down to the river-trail. According to Daylight's estimate, it was around seven o'clock; but the stars danced just as brilliantly, and faint, luminous streaks of greenish aurora still pulsed overhead.
