"The first few months I was with Edison he spent most of the time in the office at 65 Fifth Avenue. Then there was a great deal of trouble with the life of the lamps there, and he disappeared from the office and spent his time largely at Menlo Park. At another time there was a great deal of trouble with some of the details of construction of the dynamos, and Edison spent a lot of time at Goerck Street, which had been rapidly equipped with the idea of turning out bi-polar dynamo-electric machines, direct-connected to the engine, the first of which went to Paris and London, while the next were installed in the old Pearl Street station of the Edison Electric Illuminating Company of New York, just south of Fulton Street, on the west side of the street. Edison devoted a great deal of his time to the engineering work in connection with the laying out of the first incandescent electric-lighting system in New York. Apparently at that time--between the end of 1881 and spring of 1882--the most serious work was the manufacture and installation of underground conductors in this territory. These conductors were manufactured by the Electric Tube Company, which Edison controlled in a shop at 65 Washington Street, run by John Kruesi. Half-round copper conductors were used, kept in place relatively to each other and in the tube, first of all by a heavy piece of cardboard, and later on by a rope; and then put in a twenty-foot iron pipe; and a combination of asphaltum and linseed oil was forced into the pipe for the insulation. I remember as a coincidence that the building was only twenty feet wide. These lengths of conductors were twenty feet six inches long, as the half-round coppers extended three inches beyond the drag-ends of the lengths of pipe; and in one of the operations we used to take the length of tubing out of the window in order to turn it around. I was elected secretary of the Electric Tube Company, and was expected to look after its finance; and it was in this position that my long intimacy with John Kruesi started."
