"These signal stations," continued Oqua, "are under the control of the Life Saving Service, and the keepers with these glasses are always on the lookout for mariners who may be in danger, and their signal messages notify any patrols that may observe them of the nature of the danger as well as the locality of the endangered. Had the Ice King come within the radius of any of these Signal Stations at almost any other time, you would certainly have been discovered and rescued. But at the time you came into these waters the fog had effectually checkmated our observations. For this reason we are agitating for the extension of this system to medial and equatorial latitudes, as a time has come when it seems likely that other ships like the Ice King, may drift into these placid waters where sails are useless, and hence be powerless to save themselves from certain destruction by being carried into the southern verge on ocean currents which never touch the land." On the morning of the twenty-third when I awoke, the Silver King was lying at the wharf and I had a close view of the Watch Tower and its ever changing signal lights. It was more like a lofty building than a mere tower. It was a hexagon in shape, two hundred and fifty feet in height with a large platform on top, in the center of which was a huge column like the body of a tall tree branching out into numerous arms, each supporting a series of electric lights. The mechanical contrivance by which these lights were controlled was automatic, but as occasion required could be changed by the watchman in the observatory to signal any message required to all whom it might concern. This building from outside to outside was one hundred feet at the base and fifty feet at the top, while the inside diameter was the same from top to bottom. On the outside was a spiral stairway reaching from the ground to the platform at the top and in the center was an electric elevator, connected with each of the twenty stories. The hour of my departure had come. According to the program I was to bid farewell to the members of the Inner World Council and my old comrades of the Ice King and some personal friends at the top of the tower where they had already assembled. The crew of the Silver King and her throngs of excursionists had gathered on the deck and the wharf to see me take my flight. When all was ready, I took my place on the Eolus and rising a few feet sailed slowly around this magnificent ship, coming to a halt on the starboard quarter where Captain Thorfin, acting as spokesman, said:
