Editor's Notes

Through mr. G. Goddard, Sec. of Edison Electric Light Co. I am informed that you have a high-speed engine which he understands possesses peculiar merits and might be adapted to running the dynamo-electric machines. If you can give me information as to the type, whether horizontal or vertical, the range of power for which ou construct them, the limit to the speed in the revolutions to which you can attain, the form of governor and valve gear, and if automatic what would be the smallest engine which you wouldmake automatic? Iwould like particular information as to one of 120 H.P. In stating horse-power of any particular sizes please state at what boiler pressure and cut-off. What will you guaranty for economy, durability, and what approximately will be the cost per horse-power for engine. Any information, the more complete the better, I would like very much to have. P.S. How many engines have been already constructed and have any been severly tested and under what circumstances?
