At noon on the 21st of December, the shortest day, there is a note in my diary that I saw the sun's disk shining through the trees. Although fully half a degree of latitude north of the Arctic Circle, the refraction is sufficient to lift his whole sphere above the horizon. One speculates how much farther north it would be possible to see any part of the sun at noon on the shortest day; but north of here, throughout Alaska, is broken and mountainous country. We were on the northern edge of the great flat of the interior. The fifth day at the village was Christmas Eve. My boy was in a critical condition, very low and weak, with a temperature that stayed around 101° and 102°. As night approached I watched with the greatest anxiety for the party from Fort Yukon, and, just as the last lingering glow of the long twilight was fading from the south, there was a distant tinkle of bells on the trail, and faintly once and again a man's voice was raised in command and I knew that relief was at hand. The nurse had dropped everything and had come, as I felt sure she would. Gathering medicines and supplies and hiring a native dog team and driver, she had left immediately, and the round trip had been made in the shortest time it was possible to make it. It was a tremendous relief to see her step out of the rugs and robes of the toboggan and take charge of the situation in her quiet, competent way. A small, outlying cabin was selected for a hospital, the family that occupied it bundled out into a tent, and the two sick persons carefully moved into it, with whom and the mother of the sick boy the nurse took up her abode. Then there was the Christmas-tree in the chief's cabin, with little gifts for the children sent out from the mission at Fort Yukon some time before, and a dance afterward, for Christmas festivities must go on, whatever happens, at a native village. I took James's pocket-knife to him after the celebration was over, and I think he really tried to smile as he thanked me with his eyes. The next day after the services, although it was Christmas Day, we set to work on the disinfecting of the large cabin in which the sick had lain. Stringing bedclothes and wearing apparel on lines from wall to wall, and stuffing up every crack and cranny with cotton, we burned quantities of sulphur, that the nurse had brought with her, all day long.
