There are two items in recent issues I would like to call your attention to--in the May-June 68 IMA, you show a picture on page 12 of Mr. Weisel proudly posing with his Corliss engine. The model is of course of an European style stationary beam engine.

And in the July-August 68 IMA issue, Joe Hamilton in talking about the Troy, Ohio engine calls it a 715 KW machine. I would guess this to be a typographical error for 71.5 KW. as this appears to be about the size of the engine. For a 715 KW generator you'd need an engine of about 950-1000 hp and that would be a big one.

In connection with this same article, I must make a comment on the chair shown in the picture on Page 9 which is captioned to the effect that it is chained down to keep sleepy help from tipping over. I think that if this were my plant, I'd cut the chain and 'Let 'em go'. Sleeping and engine rooms don't go together. (Besides, most old timers can prop themselves in the darndest positions that they don't fall over).

Speaking of engines, I have three in my plant. They are 75 KW each, driven by horizontal 'Ames' piston valve engines. They were installed in 1900 and still average about 60 hours per week a piece. We supply light and power to a college campus here in Brooklyn, Pratt Institute by name.

Even though 2/3 of the campus is on Edison service, the plant load is still about 2/3 of what it was when the whole school was on the plant. This is a good example of how electrical consumption is increasing today. We normally run two engines, but on some days, especially near the ends of the semesters, we often have to put on a third one.
