A TRACTION ENGINE ON THE ROAD

You may know all about an engine. You may be able to build one, and yet
run a traction in the ditch the first jump.

It is a fact that some men never can become good operators of a traction
engine, and I can't give you the reason why any more than you can tell
why one man can handle a pair of horses better than another man who has
had the same advantages. And yet if you do ditch your engine a few
times, don't conclude that you can never handle a traction.
