March 4, 1891. Francis R. Upton, Esq., Gen’l. Manager, Lamp Mfg. Dep’t., Edison Gen’l. Electric Co., Harrison, N.J. Dear Sir:- We find that carbons marked Jan’y. 29- and put on test by us- and your corresponding order No. 2251- are very good. Ascertain from Force and Hickman what difference there is in the carbons. I also want you to send descriptions of orders previously sent, so I can compare. We get your orders, but don’t know how they are done; therefore cannot compare. Yours very truly, (Signed Edison)
