I now learned that as soon as the tunnel was completed, Lief and Eric had found their way to the top of our prison, and seeing the advantages that this elevation offered as an outlook, they conceived the idea of an observatory on the top, to be connected with the ship by an elevator. They took no one into their confidence but Huston, and set to work immediately. In a little over two weeks they were ready to put in the elevator which connected directly with the ship, and saved a long walk by way of the tunnel. This work had just been completed and they were enabled to give me a very unexpected but agreeable surprise on my return from one of my usual rambles. But it was no more of a surprise to me than it was to Captain Ganoe, who was just starting out to the surface through the tunnel, when Lief, Eric and myself came swinging down from the observatory on the platform which constituted the cage. Lief who was handling the rope stopped our descent just in time to prevent the platform from swinging against the Captain, who looking up exclaimed: "Hello, Jack! Where did you come from, and what is all this rigging for?" "Just ask Lief and Eric," I replied. "They have been looking out for a more direct route to the surface than by way of the tunnel. They have erected an observatory on the roof, and if you are going out for a walk, you had better take the elevator." "All right," said the Captain stepping on the platform, "but I would suggest that you ought to have a light on board, to give warning in this gloom to all whom it may concern, to get out of the way of the engine." "That can be provided for in the future," I said. "This is the first trial and we find that it works all right. Now we are ready for such improvements as you have to suggest. While the invention belongs to our Norwegian friends, we have no patent laws in this country and hence there can be no infringement. There is no restrictive legislation here to stand in the way of progress." "I think in view of all the facts," said the Captain, "that this matter had better be left in the hands of the inventors. I have no doubt that they are fully equal to the task, and they have free access to the ship's stores for that purpose. It seems to me that the improvement most needed is some contrivance that will counteract the swinging motion, and no doubt Lief and Eric have a plan already that will accomplish that."
