he boiler to the con-denser. Not only has the steam turbine justified the con-fidence of those who have labored so successfully in itsdevelopment, but no other great invention has pro-ceeded from the laboratory stage to such an importantposition in the engineering world in such a short spaceof time. This would not have happened if some in-herent drawback, such as lack of economy in steamconsumption, existed, and as the turbine has beenproved to be, for land purposes, very economical, thereseems to be no reason to doubt that marine turbines,working as they do at full load almost continually,will show likewise that the coal bill is not increased,but perhaps diminished by their use. The records of the vibrations of the hull whichwere taken during the trials by Schlicks instrumentsshowed that the vertical vibration was 60 per minuteon the run, which was due to the propellers, and whichmay be further modified. The horizontal vibrationwas almost unnoticeable, while the behavior of the (128)

The great length of this shipand the gyrostatic action of the heavy rotating massesof the machinery ought to render her almost insensibleto the heaviest Atlantic rollers; certainly as far aspitching is concerned. A more general comment upon the turbine engine,with particular reference to its use in America, is madeby Mr. Edward H. Sanborn in an article on MotivePower Appliances, in the Twelfth Census Report ofthe United States, Vol. X. part IV. Apart from its dem
