NON-ROLLING PASSENGER LINERS. 101 



some refinements in manual control valves and also in shape and contour, the tanks 

 were found to be open to the same objections as those of Sir Phillip's. 



Dr. Schlick, who had done such wonderful work in balancing marine engines, 

 then came forward with his passive "gyrostat" or "Kreisel," as he called it. This 

 was installed on a small torpedo boat and tested in the North Sea. The Admiralty 

 sent Sir William White, who, by the way, was a friend and admirer of Dr. Schlick, 

 to report upon this device, and Dr. Schlick's rights were taken over by a leading 

 English firm. The report is interesting. Sir William found this to be another de- 

 vice which depended for its action on the initial roll of the ship — that is, the quench- 

 ing moments were dependent solely upon the ship's motion — and these would have 

 been quite effective as a roll reducer had it not been for the same unavoidable lag 

 in phase, which seriously impaired their efficiency. In any event, the combined diffi- 

 culties, some of which are cited, were sufficient to prevent the adoption of this de- 

 vice, or, for large ships, even its serious consideration. 



Later the action of anti-rolling tanks came under careful review by our own 

 Taylor. This was before he became Admiral and Chief of the Bureau of Con- 

 struction of our Navy, and while he still had charge of the big experimental tank 

 at Washington, designed and constructed by him, and of the great collateral equip- 

 ment that forms a part of the experimental and model department of the Navy. 

 In this connection. Admiral Taylor, with his wonderful grasp of all this intricate 

 phenomena, designed tanks that were unique ; and to make his research and inves- 

 tigations complete he went at the matter in the most thorough manner, not confin- 

 ing his observations to one tank alone, but going to sea with a ship equipped with 

 no less than three tanks. This was the most complete equipment, and the investiga- 

 tion was one of the most searching into the action of anti-rolling tanks that have 

 ever been made the world over — as is characteristic of all of Admiral Taylor's 

 work, which is conceived from a most complete and comprehensive standpoint and 

 carried out in the most rigid and searching manner. 



It is difficult to believe that the great art of naval architecture appreciates to 

 the full the debt that it owes Admiral Taylor. Some little glimpse is had of the rela- 

 tion that this distinguished authority bears to the world-wide art, when we remember 

 that at the time the Hawk, warship of the British Admiralty, hit the Olympic near 

 Southampton, within four hours of this memorable collision both sides had tried to 

 reach Admiral Taylor by cable to retain him in the suit that they knew was imminent 

 as the result of this accident. So the Government released Admiral Taylor to the 

 Admiralty in order that important precedents might be established in the maritime 

 world. 



But to revert to Admiral Taylor's anti-rolling tank experiments. In this con- 

 nection he reached certain conclusions, as he always does. These conclusions are 

 interesting, as here we have the real crux of this whole matter. His verdict was 

 that outside of the prohibitively large weights and extremely important athwart- 

 ships space occupied by the tanks, neither the United States Navy, nor in fact any 

 navy or marine, possessed the personnel requisite to keep the period in phase rela-
