J. Smith. "WASHINGTON, February 22, 1838. " DEAR SIR : I have endeavored to approach a proper estimate of the expense attendant on preparing a complete telegraphic com munication for some distance ; and, taking into consideration the possibility that the experiment may be conclusively tried before the close of the present session of Congress, I have thought that an appropriation for fifty miles of distance would test the practicability of the Telegraph quite as satisfactorily as one hundred, be...cause the obstacles necessary to be overcome would not be more proportion ally in fifty than in one hundred; while at the same time the double circuit necessary in the fifty miles would give a single circuit of one hundred for the purpose of testing the effect of distance upon the passage of electricity. Fifty miles would require a less amount of appropriation, and the experiment could also be sooner brought to a result : Two hundred miles of wire, or wire for two circuits for fifty miles of dis tance, including the covering of the wire with cotton, at $100 per mile $20, 000 Other expenses of preparation of the wire, such as caoutchouc, wax, resin, tar, with reels for winding, soldering, etc.
