The next in the list of inquiries was for a reliable injector. I was
not surprised at this for up to a few years ago there were a great many
engines running throughout the country with only the independent or
cross-head pump, and engineers wishing to adopt the injector naturally
want the best, while others had injectors more or less unsatisfactory.
In replying to these letters I recommend one of three or four different
makes (all of which I had found satisfactory) with a request that the
party asking for same should write to me if the injector proved
unsatisfactory in any way. Of all the letters received, I never got one
stating any objection to either the Penberthy or the Metropolitan. This
fact has led me to think that probably my reputation as a judge of a
good article was safer by sticking to the two named, which I shall do
until I know there is something better. This does not mean that there
are not other good injectors, but I am telling you what I know to be
good, and not what may be good. The fact that I never received a single
complaint from either of them was evidence to me that the makers of
these two injectors are very careful not to allow any slighting of the
work. They therefore get out no defective injectors. The Penberthy is
made by The Penberthy Injector Co., of Detroit, Mich., and the
Metropolitan by The Hayden & Derby Mfg. Co., New York, N. Y.
