The Observations Summed Up in labu-
lar Form.
The Less Smoke Consumed, the Greater
Economy Of Fuel.

following are here presented: In the
ASHLAND BLOCK
there are two boilers in use, made by Gibbs u
Sternet: one il g locomotive or agricultural eta-
gine boiler, u feet long by feet diameter, With
gratc~surface measuring 4 foet by 1eet
charged through one fire-door OF an ares about
ono-tifth OF the grato-surface; no air-shuster to
fredoor Tie other boiler is Of tho ordinary tub
ular type, similar to allthosa already described,
measuring 16 feet long by feet diameter, Win
grate-surface OF feet by 1 feet 6 inches, Will
TWO fre-doors, each OF an area equal to one
fourteenth area OF grate-surface, nearly; no ar
shutters III the same, only five holes halt an
inch in dianetcr. The average pressure kept IN
the boilers for fourteen hours is 50 pounds;
amount and kind Of coal consumed, 5,000 pounds
OF Wilmington (bituminous) coal per diem; con-
sumption Of fuel per square foot OF grate-surfaco
Gncluding both boilers) per hour, llA pounds.
No apparatus is fixed to either poiler for the pre-
yention of smoke, which frequently appears in
considerable quantity from the chimney. The
locomotive boiler is shortly to bo changed Tor
larger one Of ordinary type. At present the
fires have to be forced to keep up sufficient
steam for the purposes required, viz. pumping
water for use in a water-elevator, and heating
the whole building. In the
FREMONT HOUSE
thero arc two boilers. each measuring 16 feet
long by feet inches diameter, with CRATE
surface OF S feet by feet; fre-doors Of an arcs
oqualing ono-eeventeenth OF the grate-surface,
aud fitted with small air-shutters. The boilers
nre made BY John Davis; average pressure in

used, 1G, 900 pounds per day Of Wilmington coal;

the work performed is running three elevators,
heating the whole building, aud providing steam

The boilers already described. Ali the work re-

Fuel Economlzer, but this arrangement was re-
ceutly removed, as the engineer reported that 1t

thare ara three boilers, each measuring II feet in
