\ San reporter paid visi: to the machine
shop of Messrs. Sergeant & ChillingwoE,h. in
this city, where one of the Ksely motor gen
orators is being made. Il is intended to be of
100 horsepower, but by operating it rapidly
it Will give a power of 800 horses. Its
height will be about seven and half feet.
At present the parts are either lying com
pleted on the A,'or or in prouess of prePara-
iron. seven and a half feet long and three
feet seven irches wide, upon which the super
structure Of chambers aad the accessory tubes
viii he raised The chambers are about two
feet in diameter, ard vary IN height from
two to two and half feet. They are of
massive steel, and their holloWs vary from
four 10 six inches in diameter, leaving the
walls necessarily of very great thickness, and
capable Of bearing M enormous pressure.
The difficulty hitherto has been in obtaining
metal which would retain the vapor
Experiments with generator of about
fifty horsepower on low pressure gave entire
satisfaction to the company, and Mr.. hrely
WAS advised to construct larger machine

1000 horse power, to ba endowed with sutii-
eient strength to stand the requisite force

constructed Of gun metal. \ pressure of
5000 pounds to the square inch did not burst
this metal, bat caused the vapor to ooze com
ple'ely through iis pores, much to the aston
ishmvnt Of the bys'anders.
The gun metal was Of the very best com
position used, and comprised eighty per cent
Of tin, and the res, of lead and zine. II was

answer the purpose, bat the yapor oczed
through that at still less pressure The
virtues of wrought iron and steel are now To
be tried. The chambers of Mr.. Keely's 1000
horse generator in Philadelphia have stood
pressure of 25, 800 pounds to the square inch
in the lower part, and 10000 pounds in the
upper, aud retained the vapor, but small

minor paris and by June lst n trial will pro-

horse power will likewise be tried. The

that pint Of water only would be needed

This city and Philadelphia and back. They
meant that if five gallons were used for IN

only be lost by vaporzliion through the
