Q. How should you guide a traction engine?

It must be learned by experience. Good judgment is required to make
a success of it. One man should always handle both reverse lever and
steering wheel when guiding an engine.
Q. How should the steering chains be put on a traction engine?
A. The chains should be so put on, that when the steering wheel is
turned to the right, the engine turns to the right; when wheel is
