This island was evidently the obstruction against which the ice-field had been lodged. The tower was built of dressed stones accurately piled upon each other; and at one time had apparently been surrounded by a spiral staircase which led to an observatory on top. This conclusion was the logical deduction from the existence of a spiral ledge from the base to the summit, plainly indicating that it had been used as a support for an external structure. We were now running under a full head of steam through a channel that had been formed between the ice and the island, which led into an open sea beyond. This channel brought us close to the strange tower, and as we came even with it, Captain Battell gave the word: "Starboard your helm! hard up!" "Aye, aye, sir," came the response, and the wheel fairly spun in Captain Ganoe's hands. The Ice King lurched, trembled, and in the next instant shot around the tower, and into comparatively still water, under the cover of the island, which we now discovered, extended from west to east, about two miles, in the form of a crescent, constituting a safe harbor from all storms except from the north. We determined to cast anchor until the wind had subsided and give our small crew a much needed rest. This gave me an opportunity to make sketches of the tower and island at my leisure. The rest was most welcome to officers and men after the unusual fatigues of the last few days, culminating in the excitement and extraordinary efforts of the last few hours. While we slept, the winds ceased to howl, the skies became clear, and I sketched the tower and the island while they were bathed in the glorious hues of an Arctic sunset. I applied the camera to every prominent object in sight. The island had the appearance of a segment of the top of a circular mountain which might have been, in geologic ages, the crater of a vast volcano, since which time the land had been depressed, or the water level elevated, perhaps several hundred feet. The shore-line was a granite precipice, rising to the height of about one hundred feet. Over this was a lofty covering of ice, cut into the most fantastic shapes by streams of water which come with summer and depart with winter. In places where the surface had been laid bare I could discover traces of man's handiwork, which for the present I had no opportunity to investigate, owing to the precipitous nature of the shore-line. But the object of the greatest interest was the tower. As I made my sketch, the last rays of the sun illuminated this strange guardian of these unexplored waters with a luster which impressed the beholder with a feeling of awe. We examined it closely with our glasses and speculated as to its origin. It had evidently been erected to serve some important purpose, by a people who were skilled in architecture. From its location, it might have served the purpose of a light-house in some far off time, before these regions were covered with their present mantle of ice.
