Happening into the offices of the "Maine Farmer" in 1842, Cornell saw an acquaintance of his, one F.O.J. Smith, bent over some plans for a "scraper" as Smith called it. For services rendered, Smith had been granted a one-quarter share of the telegraph patent held by Samuel F.B. Morse, and was attempting to devise a way of burying the telegraph lines in the ground in lead pipe. Ezra's knowledge of plows was put to the test and Ezra devised a special kind of plow that would dig a ditch, lay the pipe and telegraph wire in the ditch and cover it back up as it went. Later it was found that condensation in the pipes and poor insulation of the wires impeded the electrical current on the wires and so hanging the wire from telegraph poles became the accepted method.
