ship in the heavy seas she encountered in her long-dis- 

 tance runs was good, the roll from side to side having a 

 period of 18 seconds. The great length of this ship 

 and the gyrostatic action of the heavy rotating masses 

 of the machinery ought to render her almost insensible 

 to the heaviest Atlantic rollers; certainly as far as 

 pitching is concerned." 



A more general comment upon the turbine engine, 

 with particular reference to its use in America, is made 

 by Mr. Edward H. Sanborn in an article on Motive 

 Power Appliances, in the Twelfth Census Report of 

 the United States, Vol. X. part IV. 



"Apart from its demonstrated economy," says Mr. 

 Sanborn, "other important advantages are claimed for 

 the steam turbine, some of which are worthy of brief 

 mention. 



"There is an obvious advantage in economy of space 

 as compared with the reciprocating engine. The largest 

 steam turbine constructed in the United States is one of 

 3,000 horse-power, which is installed in the power 

 house of the Hartford Electric Light Company, Hart- 

 ford, Conn. The total weight of this motor is 28,000 

 pounds, its length over all is 19 feet 8 inches, and its 

 greatest diameter six feet. With the generator to which 

 it is directly connected, it occupies a floor space of 33 

 feet 3 inches long by 8 feet 9 inches wide. 



"Friction is reduced to a minimum in the steam tur- 

 bine, owing to the absence of sliding parts and the small 

 number of bearings. The absence of internal lubrica- 

 tion is also an important consideration, especially when 

 it is desired to use condensers.
