In order to get the learner started, it is reasonable to suppose
that the engine he is to run is in good running order. It would not
be fair to put the green boy on to an old dilapidated, worn out
engine, for he might have to learn too fast in order to get the
engine to running in good shape. He might have to learn so fast
that he would get the big head, or have no head at all, by the time
he got through with it. And I don’t know but that a boy without
a head is about as good as an engineer with a big head. We will,
therefore, suppose that his engine is in good running order.
(Maggard 17).

Readers of Maggard’s book feel he is speaking directly to
them, telling them what’s what:

engine, Serial No. 2058, at factory in Springfield, Ohio. Note
British design details. All four factory photographs of Kelly
engines are from the collection of Dr. Robert T. Rhode.

I am well aware that among young engineers the impression
prevails that a valve is a wonderful piece of mechanism, liable to
kick out of place and play smash generally. Now, let me tell you
right here that a valve (I mean the ordinary slide-valve such
as is used on traction and portable engines)
is one of the
simplest parts of an engine, and you are not to lose any sleep
about it, so please be patient until I am ready to introduce you to
this part of your work. You have a perfect right to know what is
wrong with the engine. (Maggard 36).

With an odd combination of solid information, acerbic wit, and
verbal grandstanding, Maggard’s chapters decoy readers into
learning how to run steam engines safely and efficiently.
