SEWAGE OF THE CITY.
CLEVELAND, Ohio, Oct. %. In 1887, the
waterworks this city, they exist at present, were
completed but with much less water to pump then than
now then about $4,000 gallons day supplied the city
The pumping engines Of the Cornish style were designed
In London but were built in NewYork. They have been
working since the completion Of the works with but
little interruption and from the duty they have per
formed as taken from the official records reflect credit
alike designer, builder, and engineer. They take
their supply water from Lake Erie and force 10 to
reservoir about 1000 feet distant and about leo feet
above surface Of the lake. In 1857 III 100000 gallons
required supply the wants Of the city, but the
demand risen until with the increase Of the popula
ton over l26O 100000 gallons needed IN 1870 To
distribute this large amount Of water less than
miles OF pipe required up TO Dec 81 1870 The
demand pipe still continues. and the city
keep pace with It, For this the engineer es
mates that less than 800 tuns Of pipe from to II
inches diameter win be required In his report he in
timated that the consumption Of water Is now about
equal to the of pump to supply" and the trs
tees therefore invited proposals from various pump
builders for engines and pump machinery The
ratio OF increase in the consumption OF water for the
past year 2soo cent, SSloO per cent greater
than that Of the preceding year. This rapid increase
and in the time additional pumping power, equal at
least to that both the old pumps should I've provided
1t order that at all times Of power may be had
equal or nearly 80, to the power in use.
The engines now In use are two in number and worked
durng se2 days. the running per day being
"a hours and minutes" increase per diem the
previous year three hours and % minutes The total
number OF strokes made by both engines $500 800
The average hight to which water pumped above
the surface Of The duty Of the
east engine is 43ss870 and the duty OF the west engine
is 42275O75 pounds OF water raised foot high with
each 100 pounds Of coal consumed. These exceedingly
satisfactory results obtained from the use as fuel
OF bituminous slack, so-called, or the waste from
the Ohio bumiDous coal, and are therefore the moro
remarkable the evaporatng power Of this coal Is only
seven poundshat that 100 pounds Of this fuel
will evapOrate pounds OF steam from water at 2l2
degrees Fahrenheit. The recorded results Of Walter r
Jehnsons experiments place the evaporatng power Of
anthracite nine TO ten pounds, and Of Cumber
lanG bitumnous at about the same The Western btu
muus Goals do not, however average more than from
seven eight pounds and this is the first recorded
experiment have seen where the evaporatlng power OF
the "slack" has been determined.
