142 PRESIDENT’S ADDRESS—SECTION H. 
Each boiler is set in fire brick, and the entire weight of each 
boiler is carried by four suspending bolts, prone ss being made 
to allow of expansion in ev ery direction. 
The fronts are of cast iron, resting on brickwork at the 
bottom, and tied sae to setting by stay bolts; each battery 
is completely tied in by stay bolts and buck stays. 
The furnaces are equipped with the “ Alves’ Patent Fuel 
Economisers,” which is a method of heating the air supplied to 
the furnaces, and feeding it to the back i the grate under the 
bridge. 
Each ash pit is closed to the atmosphere, the bottom being 
in the shape of a hopper (wrought iron), into which the dalle 
fall, and are removed through a door at the bottom. 
Under the ash pits, and below the level of B. house floor, is 
a tunnel having a continuous cast-iron floor, with a track cast 
in it similar to that in the boiler house; this allows of a 
small car being placed under the hoppers when removing the 
ashes. 
The floor space between the fronts of the boilers is covered 
with cast-iron plates, in which is cast a complete system of 
tracks for handling charging cars, the tracks extending out 
under the coal pocket, with scales arranged for weighing the 
coal on the car. 
The cast-iron floor and cars were supplied by the R. W. 
Hunt Co. . 
At the end of boiler house, and outside the building, is 
erected a coal pocket, over which a siding from the main track 
runs, and the coal dumped immediately into the pocket. From 
the pocket it can be discharged by gravity into the charging 
cars, taken into the boiler house, and shovelled from, the ear 
into the furnace. The ashes are collected in a tip car running 
under the ash pits, and tipped into a pit at end of the tunnel, 
and from there lifted by a conveyor, worked by an electric 
motor, to a hopper erected over the coal pocket; they can then 
be dumped into one of the empty coal cars, and taken away. 
The main steam piping is of steel, and is so arranged with its 
valves as to allow of any of the fourteen boilers being on any 
one of the engines, and reducing the likelihood of having to 
shut down the whole station, due to any accident to’ either 
engines or boilers, to a minimuin. 
There are two complete systems of feed mains, one for hot 
water from hot well, the other for cold water from tank con- 
nected with city mains. They are of 6-in. diameter piping 
throughout, and make complete loops in the boiler house, being 
placed in pits under the floor, running close to boiler fronts, 
and crossing over at each end of boiler house. 
The feed pumps are situated on the western side of the pump 
room. Two triplex plunger pumps are provided, each capable
