Tucker decided to establish a cache of food and fuel as far up the mountain side as he and Coello could carry fifty pounds in a single day's climb. Leaving me to reset the demoralized tents and do other chores, they started off, packing loads of about twenty-five pounds each. To me their progress up the mountain side seemed extraordinarily slow. Were they never going to get anywhere? Their frequent stops seemed ludicrous. I was to learn later that it is as difficult at a high elevation for one who is not climbing to have any sympathy for those suffering from soroche as it is for a sailor to appreciate the sensations of one who is seasick. During the morning I set up the barometers and took a series of observations. It was pleasant to note that the two new mountain aneroids registered exactly alike. All the different units of the cargo that was to be taken up the mountain then had to be weighed, so that they might be equitably distributed in our loads the following day. We had two small kerosene stoves with Primus burners. Our grub, ordered months before, specially for this climb, consisted of pemmican in 8 1/4-pound tins, Kola chocolate in half-pound tins, seeded raisins in 1-pound tins, cube sugar in 4-pound tins, hard-tack in 6 1/2-pound tins, jam, sticks of dried pea soup, Plasmon biscuit, tea, and a few of Silver's self-heating "messtins" containing Irish stew, beef à la mode, et al. Corporal Gamarra appeared during the day, having found his mule, which had strayed twelve miles down the canyon. He did not relish the prospect of climbing Coropuna, but when he saw the warm clothes which we had provided for him and learned that he would get a bonus of five gold sovereigns on top of the mountain, he decided to accept his duties philosophically. Tucker and Coello returned in the middle of the afternoon, reported that there seemed to be no serious difficulties in the first part of the climb and that a cache had been established about 2000 feet above the Base Camp, on a snow field. Tucker now assigned our packs for the morrow and skillfully prepared the tump-lines and harness with which we were to carry them.
