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.
A locomotive engineer makes a run for a hill in order that the momentum
of his train will help carry him over. It is not so with a traction and
its load; the momentum that you get don't push very hard.
The engineer who don't know how to throttle his engine never knows what
it will do, and therefore has but little confidence in it; while the
engineer who has a thorough knowledge of the throttle and uses it,
always has power to spare and has perfect confidence in his engine. He
knows exactly what he can do and what he cannot do.
The second thing for you to know is to get onto the tricks of the steer
wheel. This will come to you naturally, and it is not necessary for me
to spend much time on it.
