When the attention or engineering
experts was first drawn TO the pcani'
bilitles OF the steam turbine, as Illus

merit was the high power developed ia

electric light station in Hartford,
Conn, and The Iron Age learns tnat

when one remembers that the best

steamships and In waterworks. call for
at least one and oRe-half pounds, while
In many power plants fully three
pounds OF coal are consumed hourly
for every horsepower. In making such
a comparison, 1t Is desirable to know
Eomefhing about the grade Of fuel used.
Much depends, too. on the continuity

IL Is not incredible that the Hartford

a good prima facie case for economy.
II this Is well backed up by later ek-
perience. the steam turbine will have .
fresh claim to favor.
Il has long been automatic in marine
practice that every steam engine has

not prove any more economical than

upon an electric light station for cui-

establishments greatly. A remedy has
been found for the evil, however. Sfor-
