principle they can not see or observe anything
else. That was the case with this engineer, his mind had been
thoroughly occupied in getting all the reciprocating (moving) parts
perfectly adjusted, and if the exhaust had made all sorts of peculiar
noises, he would not have discovered it.

The one idead man will not make a successful engineer. The good engineer
can stand by and at a glance take in the entire engine, from tank to top
of smoke stack. He has the faculty of noting mentally, what he sees,
and what he hears, and by combining the results of the two, he is
enabled to size up the condition of the engine at a glance. This,
however, only come with experience, and verges on expertness. And if
you wish to be an expert, learn to be observing.

It is getting very common among engineers to use "hard grease" on the
crank pin and main journals, and it will very soon be used exclusively.
With a good grade of grease your crank will not heat near so quickly as
with oil and your engine will be much easier to keep clean; and if you
are going to be an engineer be a neat one, keep your engine clean and
keep yourself clean. You say you can't do that; but you can at least
keep yourself respectable. You will most certainly keep your engine
looking as though it had an engineer. Keep a good bunch of waste handy,
and when it is necessary to wipe your hands use the waste and not your
overalls, and when you go in to a nice dinner the cook will not say
after you go out, "Look here where that dirty engineer sat." Now boys,
these are things worth heeding. I have actually known threshing crews
to lose good customers simply because of their dirty clothes. The women
kicked and they had a right to kick. But to return to hard grease and
suitable cups for same.

In attaching these grease cups on boxes not previously arranged for
them, it would be well for you to know how to do it properly. You will
remove the journal, take a gouge and cut a clean groove across the box,
starting in at one corner, about I/8 of an inch from the point of box
and cut diagonally across coming out at the opposite corner on the other
end of box. Then start at the opposite corner and run through as
before, crossing the first groove in the center of box. Groove both
halves of box the same, being careful not to cut out at either end, as
this will allow the grease to escape from box and cause unnecessary
waste. The chimming or packing in box should be cut so
