does, and if it is necessary to use the blower in order to keep up
steam, you can conclude that your engine is in bad shape, and yet there
are times when the blower is necessary, even when your engine is in the
best of condition. For instance, when you have poor fuel and are
working your engine very light, the exhaust steam may not be sufficient
to create enough draught for poor coal, or wet or green wood. But if
you are working your engine hard the blower should never be used; if you
have bad fuel and it is necessary to stop your engine you will find it
very convenient to put on the blower slightly, in order to hold your
steam and keep the fire lively until you start again.

It will be a good plan for you to take a look at the nozzle on blower
now and then, to see that it does not become limed up and to see that it
is not turned to the side so that it directs the steam to the side of
stack. Should it do this, you will be using the steam and getting but
little, if any, benefit. It will also be well for you to remember that
you can create too much draught as well as too little; too much draught
will consume your fuel and produce but little steam.


A GOOD FIREMAN.

What constitutes a good fireman? You no doubt have heard this
expression: "Where there is so much smoke, there must be some fire."
Well, that is true, but a good fireman don't make much smoke. We are
speaking of firing with coal, now. If I can see the smoke ten miles
from a threshing engine, I can tell what kind of a fireman is running
the engine; and if there is a continuous cloud of black smoke being
thrown out of the smokestack, I make up my mind that the engineer is
having all he can do to keep the steam up, and also conclude that there
