76 EMMET—THE CURTIS STEAM TURBINE. [April 2, 
by Corliss, a certain improvement in engine economy was effected, 
and although this improvement was accompanied by no diminu- 
tion in cost, the change resulted in a very great activity in engine 
building, and the renewal of most of the large mill engines in the 
country. It is, therefore, safe to predict that the influence of the 
steam turbine will be of radical importance. The steam turbine is, 
on account of its high speed, particularly adapted to the driving 
of electric generators, and its introduction will consequently 
stimulate the use of electricity rather than other power trans- 
mitters. 
In the past the most economical use of steam has been confined 
to the most expensive and elaborate plants, while in the future it 
will be within the reach of all where condensing water is available.
