"The station was anchored by a three-inch cable, pivoted at both ends to prevent twisting. In the center of the cable were electric wires terminating at the bottom of the ocean in a large coil. This coil was laid upon one of the old Atlantic cables which had been abandoned after the invention of the sympathetic telegraph. "In the office were a set of instruments, and communication was by induction to the cable below, and thence to each end and to each station. "The normal submergence of the vessel was to within three feet of the cone. The exceptional, or rough weather, submergence was to within two feet of the top of the tower. "The weights were as follows: Pounds. Shell of vessel 1,200,000 Cone 106,000 First tower 163,000 Second tower 12,000 Seven floors 176,000 Bulkheads 100,000 Bracing and iron-work 100,000 Engines and machinery 200,000 Stores for 100 persons (six months) 75,000 Stores for vessels 50,000 Cable 260,000 --------- Total weights 2,442,000 "The normal displacement of the vessel was 57,225 cubic feet, or 3,664,000 pounds. This displacement, less the weights, gave an excess of 1,200,000 pounds, which was compensated for by the sand in the sand-chamber--the capacity of that chamber being 1,300,000 pounds. "During stormy and rough weather, to decrease the pressure of the winds and waves upon the towers, and to increase the stability of the vessel, water could be admitted into the water-chambers, and the vessel would sink until the water line was within two feet of the top of the first tower, for the displacements to be overcome were: Pounds. Three feet of the shell 135,000 Cone 180,000 First tower 149,000 ------- Total 464,000 "The capacity of the water-chamber being 677,000 pounds, there was a large excess over this displacement; this excess was to compensate for loss of weight by stores being used, taken out, etc. * * * * * "The station carries a flag at its peak, by day, with its station number thereon; at night it shows a 25,000 candle-power light; its interior, also, is lighted by electricity. * * * * * "The plans of Mr. Louis were accepted, and in less than three years a line of thirty-eight stations were placed across the Atlantic Ocean. * * * * *
