always be kept in order, for, should the pump refuse to work, you have
only to start your injector and use it until such time as you can remedy
the trouble.


We have now explained how you get your water supply. You understand that
you must have water first and then fire. Be sure that you have the
water supply first.

THE BLOWER

The blower is an appliance for creating artificial draught and consists
of a small pipe leading from some point above the water line into the
smoke stack, directly over the tubes, and should extend to the center of
stack and terminate with a nozzle pointing directly to top and center of
stack; this pipe is fitted with a globe valve. When it is required to
rush your fire, you can do so by opening this globe and allowing the
steam to escape into the stack. The force of the steam tends to drive
the air out of the stack and the smoke box, this creates a strong
draught. But you say, "What if I have no steam?" Well, then don't blow,
and be patient till you have enough to create a draught; and it has been
my experience that there is nothing gained by putting on the blower
before having fifteen pounds of steam, as less pressure than this will
create but little draught and the steam will escape about as fast as it
is being generated. Be patient and don't be everlastingly punching at
the fire. Get your fuel in good shape in fire box and shut the door and
go about your business and let the fire burn.

Must the blower be used while working the engine. No. The exhaust steam
which escapes into the stack, does exactly what we stated the blower
