June 16, 1891. Mr. E.C. Felton, Sup’t., Pennsylvania Steel Company, Steelton, Pa. Dear Sir:- We have tested the eight samples of bars referred to in your letter of 5th instant, and we have instructed our Schenectady Works to send you a pattern of a machine for, [illegible crossout] steel coating. In this casting please keep the carbon within 415; lower, if possible, but not higher. The phosphorous may be up to .1, the manganese up to .5, the silicon up to [illegible crossout] and the suplhur up to .05. It is of course desirable that these should all be as low as possible, but within these limits you can select whatever quantities may be necessary in order to get the casting free from blow holes. We should be further obliged if you would send us two or three rings cast from the same heat by which we can arrive at the magnetic quality of the metal in the machine you will send up from Schenectady, [illegible handwriting] Yours truly, EDISON LABORATORY By A.W.
