It was now the 20th of Feb., and it was determined that the work of exploration should commence. The dog-teams and sledges were brought out and provisioned for a journey to the eastward under the direction of Captain Battell. Captain Ganoe, Pat O'Brien, Mike Gallagher, Paul Huston, the two Norwegian sailors and myself remained on the ship. The sledge party was to be absent a month and possibly longer. Captain Battell wanted to make some thorough observations on the eastern borders of the ice-field, and take soundings if he could reach open water. We still had some weeks of Arctic night before us, but the full, round moon and the brilliant Aurora, made every object visible for a long distance. The weather was intensely cold, but the scenery was so attractive that I spent much of my time exploring the ice-field in the immediate vicinity of the ship. Many were the weird and fantastic scenes that I sketched, and many the strolls I took in a vain effort to find some prominent point from which with my glass I could get an unobstructed view of the horizon. But like our prison in the ice, all nature seemed cramped. The starry vault was contracted by the obscuration of stars which I thought should have been visible above the horizon. I kept searching for an elevated point of view, but this seemed always just a little ahead. These rambles often extended for miles and occupied hours. Returning from one of them, I was met by Lief and Eric who pointed to the crest of the mountain of ice that formed the roof of our prison, and beckoned me to follow them. I did so and found that they had cut an inclined road around the icy mountain to the apex, where they had erected an observatory out of ice blocks. It was built over a rift in the roof of our prison that was directly above the ice bench on the larboard near the mouth of the tunnel. The wall at this point was almost perpendicular, and with but little labor they were able to put in an elevator, consisting simply of a platform secured by ropes, and attached to a pulley inside the observatory. They showed me what they had done, and to convince me that it was entirely safe, they let themselves down on the elevator and raised themselves up again, much as a painter handles his swinging scaffold, but more rapidly. I was pleased with the contrivance, and more with the interest taken by Lief and Eric in making arrangements to facilitate my observations. I did not hesitate to take my place on the platform with them and return to the ship by this direct route.
