George Edward Harding in a recent
paper, forshadows a remarkable devel-
opment in the use Of electric elevators,
which, he holds, will before long as
surely supersede the hydraulic elevator
for the highest class Of service as. the
hydraulic has, in its day taken the
place Of the steam elevator. The

problems involved in the service Of a

these problems that of the elevator SER

ute there was no particular necessity
for being able to run it ut variable
speeds, and 1t served fairly well for iso-

is imperative, not alone Tor comfort
and accuracyrin starting and stopping
but for the satisfactory operation of a

Mr.. Harding maintains that the electric
elevator has proved its unquestionable.
superiority over every other system.
He adverts to the fact that some TWEEN
" years ago he, was one OF the advO-
Gates OF the hydraulic elevator, then
coming into vogue and he told a. lead
Ing elevator manufacturer that the hy-
|draulic machine would replace the
steam machine, which was at that time
In high favor. The statement was RI
Fdiculed. but the chnnge to the new
method sOOn became general. The rec.
ignition OF the adaptability Of the cleo
trio elevator TO modern conditions ID

have demonstrated that the machine Ii
absolutely safe. It occupies but little
room. and renders unnecessary the
loss Of space, incident to the cutting up
OF the building.-It has tremendous lift
Ing capacity, and Incapable OF amy re-
speed. Its motion Ia smooth,
and In starting and stopping the usual
UNPLEASANT features are eliminated.
Tho current can be taken from the
street or from n private plant. The
