An autumnal journey of special interest was Hayes's visit to "My Brother John Glacier," near Port Foulke, which, up to that time, was the most northerly and one of the most successful attempts to penetrate the glacier-covering of Greenland, known commonly as the "Inland Ice." With seven men he penetrated some forty miles or more on the ice, when the temperature, sinking to thirty-four degrees below zero, with wind, compelled their immediate return. The ice changed gradually, as they went inland, from rough to smooth, and the angle of rise decreased from six to two degrees at their highest, over five thousand feet. A snow-storm broke on them, and, as Hayes describes, "fitful clouds swept over the face of the full-orbed moon, which, descending toward the horizon, glimmered through the drifting snow that hurled out of the illimitable distance, and scudded over the icy plains--to the eye, in undulating lines of downy softness; to the flesh, in showers of piercing darts." Suddenly misfortunes came on them. Peter, an Esquimau dog-driver, brought from Upernivik, deserted. Hans Hendrik, in his interesting "Memoirs," says: "In the beginning of the winter Peter turned a Kivigtok, that is, fled from human society to live alone up the country. We were unable to make out what might have induced him to do so. Searching for him, at last I found his footprints going to the hills." The poor native was never seen alive, but it eventually transpired that he sought shelter in a remote and rarely visited Esquimau hut, where he died of starvation, his body being found in a very emaciated condition by an Etah native the following spring. Next the dogs began to die of distemper, which led up to the death of Sontag, the astronomer. By the 21st of December only nine remained of thirty fine dogs, and in this contingency it was decided to open up communication with the Esquimaux of Whale Sound, some one hundred and fifty miles to the south, for the purchase of dogs. For this journey Sontag volunteered, and with him went Hans as dog-driver. Hayes waited week after week, but no news came from either Sontag or Hans. Then feelings of uneasiness gave place to alarm and fear; for a journey of Dodge, first mate, proved that the travellers had gone outside Cape Alexander, where the floe had broken, so that possibly they had been lost on drifting ice. Hayes was projecting a personal search on January 29th, when two Esquimaux visited the ship and reported that Sontag was dead. They proved to be advance-couriers of Hans, who arrived a few days later, with only five of his nine dogs remaining.
