then with a jerk and a snort he yanks the separator out of the holes,
and the onlookers think he has about all he can pull.

Now these are facts, and they cannot be put too strong, and if you are
going to depend on your muscle to run your engine, don't ask any more
money than you would get at any other day labor.

You are not expected to become an expert all at once. Three things are
essential to be able to handle a traction engine as it should be
handled.

First, a thorough knowledge of the throttle. I don't mean that you
should simply know how to pull it open and shut it. Any boy can do that.
But I mean that you should be a good judge of the amount of power it
will require to do what you may wish to do, and then give it the amount
of throttle that it will require and no more. To illustrate this I will
give an instance.

An expert was called a long distance to see an engine that the operator
said would not pull its load over the hills he had to travel.

The first pull he had to make after the expert arrived was up the worst
hill he had. When he approached the grade he threw off the governor
belt, opened the throttle as wide as he could get it, and made a run for
the hill. The result was, that he lifted the water and choked the
engine down before he was half way up. He stepped off with the remark,
"That is the way the thing does." The expert then locked the hind wheels
of the separator with a timber, and without raising the pressure a
pound, pulled it over the hill. He gave it just throttle enough to pull
the load, and made no effort to hurry ii, and still had power to spare.
