CHAPTER V

      At Sixty Mile they restocked provisions, added a few pounds of letters to their load, and held steadily on. From Forty Mile they had had unbroken trail, and they could look forward only to unbroken trail clear to Dyea. Daylight stood it magnificently, but the killing pace was beginning to tell on Kama. His pride kept his mouth shut, but the result of the chilling of his lungs in the cold snap could not be concealed. Microscopically small had been the edges of the lung-tissue touched by the frost, but they now began to slough off, giving rise to a dry, hacking cough. Any unusually severe exertion precipitated spells of coughing, during which he was almost like a man in a fit. The blood congested in his eyes till they bulged, while the tears ran down his cheeks. A whiff of the smoke from frying bacon would start him off for a half-hour's paroxysm, and he kept carefully to windward when Daylight was cooking.

      They plodded days upon days and without end over the soft, unpacked snow. It was hard, monotonous work, with none of the joy and blood-stir that went with flying over hard surface. Now one man to the fore in the snowshoes, and now the other, it was a case of stubborn, unmitigated plod. A yard of powdery snow had to be pressed down, and the wide-webbed shoe, under a man's weight, sank a full dozen inches into the soft surface. Snowshoe work, under such conditions, called for the use of muscles other than those used in ordinary walking. From step to step the rising foot could not come up and forward on a slant. It had to be raised perpendicularly. When the snowshoe was pressed into the snow, its nose was confronted by a vertical wall of snow twelve inches high. If the foot, in rising, slanted forward the slightest bit, the nose of the shoe penetrated the obstructing wall and tipped downward till the heel of the shoe struck the man's leg behind. Thus up, straight up, twelve inches, each foot must be raised every time and all the time, ere the forward swing from the knee could begin.

      On this partially packed surface followed the dogs, the man at the gee-pole, and the sled. At the best, toiling as only picked men could toil, they made no more than three miles an hour. This meant longer hours of travel, and Daylight, for good measure and for a margin against accidents, hit the trail for twelve hours a day. Since three hours were consumed by making camp at night and cooking beans, by getting breakfast in the morning and breaking camp, and by thawing beans at the midday halt, nine hours were left for sleep and recuperation, and neither men nor dogs wasted many minutes of those nine hours.

      At Selkirk, the trading post near Pelly River, Daylight suggested that Kama lay over, rejoining him on the back trip from Dyea. A strayed Indian from Lake Le Barge was willing to take his place; but Kama was obdurate. He grunted with a slight intonation of resentment, and that was all. The dogs, however, Daylight changed, leaving his own exhausted team to rest up against his return, while he went on with six fresh dogs.

      They travelled till ten o'clock the night they reached Selkirk, and at six next morning they plunged ahead into the next stretch of wilderness of nearly five hundred miles that lay between Selkirk and Dyea. A second cold snap came on, but cold or warm it was all the same, an unbroken trail. When the thermometer went down to fifty below, it was even harder to travel, for at that low temperature the hard frost-crystals were more like sand-grains in the resistance they offered to the sled runners. The dogs had to pull harder than over the same snow at twenty or thirty below zero. Daylight increased the day's travel to thirteen hours. He jealously guarded the margin he had gained, for he knew there were difficult stretches to come.

      It was not yet quite midwinter, and the turbulent Fifty Mile River vindicated his judgment. In many places it ran wide open, with precarious rim-ice fringing it on either side. In numerous places, where the water dashed against the steep-sided bluffs, rim-ice was unable to form. They turned and twisted, now crossing the river, now coming back again, sometimes making half a dozen attempts before they found a way over a particularly bad stretch. It was slow work. The ice-bridges had to be tested, and either Daylight or Kama went in advance, snowshoes on their feet, and long poles carried crosswise in their hands. Thus, if they broke through, they could cling to the pole that bridged the hole made by their bodies. Several such accidents were the share of each. At fifty below zero, a man wet to the waist cannot travel without freezing; so each ducking meant delay. As soon as rescued, the wet man ran up and down to keep up his circulation, while his dry companion built a fire. Thus protected, a change of garments could be made and the wet ones dried against the next misadventure.

      To make matters worse, this dangerous river travel could not be done in the dark, and their working day was reduced to the six hours of twilight. Every moment was precious, and they strove never to lose one. Thus, before the first hint of the coming of gray day, camp was broken, sled loaded, dogs harnessed, and the two men crouched waiting over the fire. Nor did they make the midday halt to eat. As it was, they were running far behind their schedule, each day eating into the margin they had run up. There were days when they made fifteen miles, and days when they made a dozen. And there was one bad stretch where in two days they covered nine miles, being compelled to turn their backs three times on the river and to portage sled and outfit over the mountains.

      At last they cleared the dread Fifty Mile River and came out on Lake Le Barge. Here was no open water nor jammed ice. For thirty miles or more the snow lay level as a table; withal it lay three feet deep and was soft as flour. Three miles an hour was the best they could make, but Daylight celebrated the passing of the Fifty Mile by traveling late. At eleven in the morning they emerged at the foot of the lake. At three in the afternoon, as the Arctic night closed down, he caught his first sight of the head of the lake, and with the first stars took his bearings. At eight in the evening they left the lake behind and entered the mouth of the Lewes River. Here a halt of half an hour was made, while chunks of frozen boiled beans were thawed and the dogs were given an extra ration of fish. Then they pulled on up the river till one in the morning, when they made their regular camp.

      They had hit the trail sixteen hours on end that day, the dogs had come in too tired to fight among themselves or even snarl, and Kama had perceptibly limped the last several miles; yet Daylight was on trail next morning at six o'clock. By eleven he was at the foot of White Horse, and that night saw him camped beyond the Box Canon, the last bad river-stretch behind him, the string of lakes before him.

      There was no let up in his pace.
