When I speak of knitting together breaks in the trail, I mean simply that the passage of the supporting party from that point where the trail was broken by the movement of the ice to the point where the trail went on again, some distance either to the east or west, would itself renew the broken trail, the passage of the men and dog teams packing down the ice and snow. So that when the main party came back it would simply follow the track of the supporting party, and not have to scout for the trail.
As a result of this method of keeping the return trail continuously open, when the main party starts to return it has a continuous trail back to the land, which it can follow with from fifty to one hundred per cent. greater speed than it was possible to make on the outward journey. The reasons for this are obvious: no time is wasted in selecting and breaking a trail; the dogs are more energetic when following a beaten track and when on the road home; no time is wasted in making camp, the snow igloos built on the outward journey being reoccupied on the return journey.
It must be understood that when each supporting party reached the land again, its work in regard to the polar dash was over. It did not come back onto the ice with any further supplies for the main party.
At the very end, when the supporting parties have performed their important work of trail-breaking and transportation of supplies, the main party for the final journey must be small and carefully selected, as the small party resulting from the successive selection of the fittest, can travel much faster than a large one.
Each division of four men was absolutely independent and had its complete traveling outfit; in fact, except for the alcohol stove and cooking utensils, each sledge was complete in itself. On each sledge were the provisions for men and dogs, and clothing for the driver. The standard sledge load would support the driver and the dog team for about fifty days, and by sacrificing a few dogs and using them as food for the other dogs and the men, this time could have been extended to sixty days. Had any sledge and its provisions been cut off from the rest of the division, the man with it would have had everything he needed, except the cooking outfit. Had the sledge which carried the alcohol stove been lost, either in a lead or otherwise, the party to which it belonged would have had to double up with one of the other divisions.
The new alcohol stove, the design of which I had perfected during the winter, was used altogether on this northern sledge trip. We did not carry oil-stoves at all, except some very small ones with two-inch wicks, which we used for drying mittens.
The standard method for loading each sledge was as follows: On the bottom was a layer of dog pemmican in red tins, covering the entire length and width of the sledge; on this were two tins of biscuit, and crew pemmican in blue tins; then the tins of alcohol and condensed milk, a small skin rug for the man to sleep on at night in the igloo, snowshoes and spare footgear, a pickax and a saw knife for cutting snow blocks. Practically the only extra items of wearing apparel which were carried were a few pairs of Eskimo sealskin kamiks (boots), for it can readily be imagined that several hundred miles of such walking and stumbling over snow and ice would be rather hard on any kind of footgear which could be made.
Compactness was the main idea in packing one of these sledges, the center of gravity of the load being brought as low as possible in order that the sledges might not easily overturn.
The standard daily ration for work on the final sledge journey toward the Pole on all expeditions has been as follows:
1 lb. pemmican, 1 lb. ship's biscuit, 4 oz. condensed milk, 1/2 oz. compressed tea, 6 oz. liquid fuel, alcohol or petroleum. A total of 2 lbs. 4½ oz. of solids per man, per day.
On this ration a man can work hard and keep in good condition in the lowest temperatures for a very long time. I believe that no other item of food, either for heat or muscle building, is needed.
The daily ration for the dogs is one pound of pemmican per day; but so hardy are these descendants of the arctic wolves that when there is a scarcity of food they can work for a long time on very little to eat. I have, however, always endeavored so to proportion provisions to the length of time in the field, that the dogs should be at least as well fed as myself.
A part of the scientific work of the expedition was a series of deep-sea soundings from Cape Columbia to the Pole. The sounding apparatus of the expedition on leaving Cape Columbia comprised two wooden reels of a length equal to the width of the sledge, a detachable wooden crank to go on each end of the reel, to each reel a thousand fathoms (six thousand feet) of specially made steel piano wire of a diameter .028 inches, and one fourteen-pound lead having at its lower end a small bronze clam-shell device, self-tripping when it reached the bottom, for the purpose of bringing up samples of the ocean bed. The weights of this outfit were as follows: each thousand fathoms of wire 12.42 pounds, each wooden reel 18 pounds, each lead 14 pounds. A complete thousand-fathom outfit weighed 44.42 pounds. The two outfits, therefore, weighed 89 pounds, and a third extra lead brought this total up to 103 pounds.
Both the sounding leads and the wire were made especially for the expedition, and so far as I know they were the lightest, for their capacity, that have ever been used.
One sounding apparatus was carried by the main division and the other by the pioneer party, in the early stages of our progress. When there was a lead we sounded from the edge of it; when there was no open water we made a hole in the ice if we could find any that was thin enough for the purpose.
Two men could readily make these deep-sea soundings by reason of the lightness of the equipment.
The distance which we traveled day by day was at first determined by dead reckoning, to be verified later by observations for latitude. Dead reckoning was simply the compass course for direction, and for distance the mean estimate of Bartlett, Marvin, and myself as to the length of the day's march. On board ship dead reckoning is the compass course for direction and the reading of the log for distance. On the inland ice of Greenland my dead reckoning was the compass course, and the reading of my odometer, a wheel with a cyclometer registering apparatus. This could not possibly be used on the ice of the polar sea, as it would be smashed to pieces in the rough going. One might say in general that dead reckoning on the polar ice is the personal estimate of approximate distance, always checked and corrected from time to time by astronomical observations.
Three members of the expedition had had sufficient experience in traveling over arctic ice to enable them to estimate a day's journey very closely. These three were Bartlett, Marvin, and myself. When we checked up our dead reckoning by astronomical observations, the mean of our three estimates was found to be a satisfactory approximation to the results of the observations.
It goes without saying that mere dead reckoning, entirely unchecked by astronomical observations, would be insufficient for scientific purposes. During the earlier stages of our journey there was no sun by which to take observations. Later, when we had sunlight, we took what observations were necessary to check our dead reckonings—but no more, since I did not wish to waste the energies or strain the eyes of Marvin, Bartlett, or myself.
As a matter of fact observations were taken every five marches, as soon as it was possible to take them at all.
CHAPTER XXIII OFF ACROSS THE FROZEN SEA AT LASTThe work of the expedition, to which all the former months of detail were merely preliminary, began with Bartlett's departure from the Roosevelt on the 15th of February for the final sledge journey toward the Pole. The preceding summer we had driven the ship through the almost solid ice of the channels lying between Etah and Cape Sheridan; we had hunted through the long twilight of the autumn to supply ourselves with meat; we had lived through the black and melancholy months-long arctic night, sustaining our spirits with the hope of final success when the returning light should enable us to attack the problem of our passage across the ice of the polar sea. Now these things were all behind us, and the final work was to begin.
It was ten o'clock on the morning of February 22d—Washington's Birthday—when I finally got away from the ship and started on the journey toward the Pole. This was one day earlier than I had left the ship three years before on the same errand. I had with me two of the younger Eskimos, Arco and Kudlooktoo, two sledges and sixteen dogs. The weather was thick, the air was filled with a light snow, and the temperature was 31° below zero.
There was now light enough to travel by at ten o'clock in the morning. When Bartlett had left the ship a week before, it was still so dark that he had been obliged to use a lantern in order to follow the trail northward along the ice-foot.
When I finally got away from the ship, there were in the field, for the northern work, seven members of the expedition, nineteen Eskimos, one hundred and forty dogs, and twenty-eight sledges. As already stated, the six advance divisions were to meet me at Cape Columbia on the last day of February. These parties, as well as my own, had all followed the regular trail to Cape Columbia, which had been kept open during the fall and winter by the hunting parties and supply-trains. This trail followed the ice-foot along the coast the greater part of the way, only taking to the land occasionally to cut across a peninsula and thus shorten the road.
On the last day of February Bartlett and Borup got away to the North with their divisions, as soon as it was light enough to travel. The weather still remained clear, calm, and cold. After the pioneer division had started north, all the remaining sledges were lined up, and I examined them to see that each had the standard load and full equipment. On leaving the Roosevelt I had in the field exactly enough dogs to put twenty teams of seven dogs each on the ice, and had counted on doing this; but while we were at Cape Columbia the throat distemper broke out in one team, and six dogs died. This left me only enough for nineteen teams.
My plans were further disarranged by the disabling
