The remark that this is age Of progress beyond

cit consists Of a rovel process by which the great
" heat that escapes into the air in the waste
or exhaust steam from engines Is utilized by con-
duetiug il through the tubes Of boiler filed with
the bsulphde of carbon, fluid hich boils at ITO
degrees Fahrenheit, and nc the temperature Of eK-
haust steam gives pressure Of 65 pounds to the
inch In the boiler - the vapOr formed in this boiler
is used to drive an engine instead Of steam, and
AFTER being used is condensed by cooling, pumped
into the boiler again and used continuously without
loss.
'sCarefuIly male experiments prove that by means
Of this process the same fuel required to pro-
duce 100 horsepower with the best engines in use
will produce 25O horsepower, showing a gain OF
l5O per cent. in the amount Of power obtained by
the consumption Of fuel
- For the purpose OF making careful test Of the
value Of this process, two engines Of the same

W. Bacon, the oldest and most experienced engineer
in the city, showed that while the first engine,

the waste heat escaping in the exhaust from the first,

- The amount of coal required to run a steam en-
gne Of 100 horsepower Of the best class in use at
the present time, is about 1000 pounds per day.
600 tons year ; by means of this discovery the
same engine can be run with 900 pounds of coal
per day, 24O tons year, thus saving 800 tons Of
coal year for each hundred horsepower produced.
At $50 per ton for coal, the amount saved in q
year for each hundred horsepower is 81, 700.
- For steam vessels the advantages of this process
still greater than for stationary engines, a
large amount of room in the ship, at present

can be used to take additional freight, thus gaining
