They left the vessel on the 4th of June, and made for the Humboldt Glacier. Here Morton was joined by Hans with the dog-sledge, and the two set out on the 18th June, pursuing a northerly course nearly parallel with the glacier, and from 4 to 7 miles distant from it, according to the condition of the ice. The icebergs given off by the glacier presented great difficulties, but these were finally overcome. On the 21st of June, Kennedy Channel was sighted, and they directed their course towards the cape at the eastern side of the entrance—Cape Andrew Jackson. Here they found open water, and it was with great difficulty that the cape was rounded. Still proceeding north, they reached Cape Constitution in latitude 81° 22′. An attempt to pass this cape failed. Morton climbed up the cliff to a height of 500 feet, and could get no farther. As far as he could see not a speck of ice was visible. He stated: “As far as I could discern, the sea was open, a swell coming in from the northward and running crosswise, as if with a small eastern set. The wind was due north—enough of it to make white caps—and the surf broke in on the rocks below in regular breakers. The sky to the north-west was of dark rain-cloud, the first that I had seen since the brig was frozen up. Ivory gulls were nesting in the rocks above me, and out to sea were mollemoke and silver-backed gulls. The ducks had not been seen north of the first island of the channel, but petrel and gulls hung about the waves near the coast.” Morton was absent on this journey thirty days. The open condition of Kennedy Channel, discovered by him, had a most important bearing on some of the expeditions which followed Kane’s. It gave strong support to the theory of an open polar sea, which was believed in by many until the British Expedition of 1875. Dr. Kane himself wavered between the arguments for and against. He, however, was aware of the fact that open water, which had frequently been described as a polar sea, had been found by many explorers in various parts of the Arctic regions, which on further investigation was found to be merely temporary. And Dr. Kane, after referring to this fact, wrote: “All these illusory discoveries were no doubt chronicled with perfect integrity; and it may seem to others, as since I have left the field it sometimes does to myself, that my own, though on a larger scale, may one day pass within the same category.” All the sledge-parties had now returned to the brig, and the season of Arctic travel had ended. The question now to be faced was how they were to pass a second winter in the event of the ice not liberating the brig, which seemed likely. As Dr. Kane remarked, “there never was, and I trust never will be, a party worse armed for the encounter of a second Arctic winter. We have neither health, fuel, nor provisions.”
