214/226 Letterhead of Edison Electric Co. Office of Second Vice-President. CONFIRMATION OF MESSAGE. Name of Person Sending Name of Person Receiving Time Date Young D.M. II.30 20/I From whom received , Mr. John Kruesi General Manager Schenectady To whom sent, Mr. A.K. Kennelly, Consulting Electrician I have received the following valuable information by Cable from Siemens & Halske:- “The entire Cables used by the government have earth returns. Charge depends upon ratio between diameter of copper and thickness of insulation. One millimeter of copper and 2 8./I0 of insulation is .02 microfarad of insulation with T.C. mass and jute: Would it be possible for you to come up here as we have a number of Cables ready for test. One of them is 400 feet length. It seems to me that we could reach a conclusion much more quickly than if we sent one cable to you by express and made the other tests here. Sent to Mr. McGuire at Laboratory at 12 A.M.
