With weary nerves, and with compass in hand, my lonely march ahead of the sledges continued day by day. Progress was satisfactory. We had passed the eighty-ninth and eighty-eighth parallels. The eighty-seventh and the eighty-sixth would soon be under foot, and the sight of the new lands should give encouragement. These hard-fought times were days long to be remembered. The lack of cerebral stimulation and nutrition left no cellular resource to aid the memory of those fateful hours of chill.
The long strain of the march had established a brotherly sympathy amongst the trio of human strugglers. The dogs, though still possessing the savage ferocity of the wolf, had taken us into their community. We now moved among them without hearing a grunt of discord, and their sympathetic eyes followed until we were made comfortable on the cheerless snows. If they happened to be placed near enough, they edged up and encircled us, giving the benefit of their animal heat. To remind us of their presence, frost-covered noses were frequently pushed under the sleeping bag, and occasionally a cold snout touched our warm skin with a rude awakening.
We loved the creatures, and admired their superb brute strength. Their superhuman adaptability was a frequent topic of conversation. With a pelt that was a guarantee against all weather condition, they threw themselves down to the sweep of winds, in open defiance of death-dealing storms. Eating but a pound of pemmican a day, and demanding neither water nor shelter, they willingly did a prodigious amount of work and then, as bed-fellows, daily offered their fur as shelter and their bones as head-rests to their two-footed companions. We had learned to appreciate the advantage of their beating breasts. The bond of animal fellowship had drawn tighter and tighter in a long run of successive adventures. And now there was a stronger reason than ever to appreciate power, for together we were seeking an escape from a world which was never intended for creatures with pulsating hearts.
Much very heavy ice was crossed near the eighty-eighth parallel, but the endless unbroken fields of the northward trails were not again seen. Now the weather changed considerably. The light, cutting winds from the west increased in force, and the spasmodic squalls came at shorter intervals. The clear purples and blues of the skies gradually gave place to an ugly hue of gray. A rush of frosty needles came over the pack for several hours each day.
The inducement to seek shelter in cemented walls of snow and to wait for better weather was very great. But such delay would mean certain starvation. Under fair conditions, there was barely food enough to reach land, and even short delays might seriously jeopardize our return. We could not, therefore, do otherwise than force ourselves against the wind and drift with all possible speed, paying no heed to unavoidable suffering. As there was no alternative, we tried to persuade ourselves that existing conditions might be worse than they were.
The hard work of igloo building was now a thing of the past—only one had been built since leaving the Pole, and in this a precious day was lost, while the atmospheric fury changed the face of the endless expanse of desolation. The little silk tent protected us sufficiently from the icy airs. There were still 50° of frost, but, with hardened skins and insensible nerve filaments, the torture was not so keenly felt. Our steady diet of pemmican, tea and biscuits was not entirely satisfactory. We longed for enough to give a real filling sense, but the daily ration had to be slightly reduced rather than increased. The change in life from winter to summer, which should take place at about this time of the year, was, in our case, marked only by a change in shelter, from the snow house to the tent, and our beds were moved from the soft snow shelf of the igloo to the hard, wind-swept crust.
In my watches to get a peep of the sun at just the right moment, I was kept awake during much of the resting period. For pastime, my eyes wandered from snorting dogs to snoring men. During one of these idle moments there came a solution of the utility of the dog's tail, a topic with which I had been at play for several days. It is quoted here at the risk of censure, because it is a typical phase of our lives which cannot be illustrated otherwise. Seeming trivialities were seized upon as food for thought. Why, I asked, has the dog a tail at all? The bear, the musk ox, the caribou and the hare, each in its own way, succeeds very well with but a dwarfed stub. Why does nature, in the dog, expend its best effort in growing the finest fur over a seemingly useless line of tail bones? The thing is distinctive, and one could hardly conceive of the creature without the accessory, but nature in the Arctic does not often waste energy to display beauties and temperament. This tail must have an important use; otherwise it would soon fall under the knife of frost and time. Yes! It was imported into the Arctic by the wolf progenitor of the dog from warmer lands, where its swing served a useful purpose in fly time. A nose made to breathe warm air requires some protection in the far north and the dog supplied the need with his tail. At the time when I made this discovery a cold wind, charged with cutting crystal, was brushing the pack. Each dog had his back arched to the wind and his face veiled with an effective curl of his tail. Thus each was comfortably shielded from icy torment by an appendage adapted to that very purpose.
In the long tread over snowy wastes new lessons in human mechanism aroused attention. At first the effort to find a workable way over the troublesome pack surface had kept mind and body keyed to an exciting pitch, but slowly this had changed. By a kind of unconscious intuition, the eye now found easy routes, the lower leg mechanically traveled over yards and miles and degrees without even consulting the brain, while the leg trunk, in the effort to conserve energy, was left in repose at periods during miles of travel, thus saving much of the exertion of walking.
The muscles, thus schooled to work automatically, left the mind free to work and play. The maddening monotone of our routine, together with the expenditure of every available strain of force, had left the head dizzy with emptiness. Something must be done to lift the soul out of the boreal bleach.
The power of the mind over the horse-power of the body was here shown at its best. The flesh proved loyal to the gray matter only while mental entertainment was encouraged. Thus aching muscles were persuaded to do double duty without sending up a cry of tired feeling. The play of the mind with topics of its own choosing is an advantage worth seeking at all times. But, to us, it multiplied vital force and increased greatly the daily advance. Science, art and poetry were the heights to which the wings of thought soared. Beginning with the diversion of making curious speculations on subjects such as that of the use of the dog's tail and the Arctic law of animal coloring, the first period of this mental exercise closed with my staging a drama of the comedies and tragedies of the Eskimos.
