Dr. Herbert Kienzle, a clock-maker, of 309 West 86th Street, had written to his father in Germany bitterly assailing the United States for shipping munitions, and enclosed in his letters information of certain American firms, such as Browne & Sharp, of Providence, and the Chalmers Motor Car Company, of Detroit, who were reputed to be manufacturing them. These letters had been turned over to Jonnersen, who showed them to Fay as suggestions. Upon his arrival in New York, then, Fay called on Kienzle, who, though he was friendly enough, was reluctant to know of the details Fay had planned. Dr. Kienzle introduced Fay to von Papen, and later to Max Breitung, from whom he purchased a quantity of potassium chlorate. The deserter found his brother-in-law, Walter Scholz, working as a gardener on an estate near Waterford, Connecticut, and brought him to New York on a salary of $25 a week. The two crossed the Hudson to Weehawken, N. J., and set to work to make bombs. Fay had a theory that a bomb might be attached to the rudder of a ship, and so set as to explode when the rudder, swinging to port, wound a ratchet inside the device which would release a hammer upon a percussion cap. Their plan was to have the parts manufactured at machine shops, assemble and fill them themselves, and then steal up the waterfront in the small hours and attach the infernal machines to outward bound vessels. Fay even counted on disarming the police boats before setting out. It took the two some three months to get the parts made and properly adjusted. Meanwhile they employed their spare hours in cruising about the harbor in a motor-boat. A machinist in West 42nd Street, New York, made the zinc tank which they used as a model, and the two conspirators shortly opened a garage in Weehawken where they could duplicate the bomb cases unmolested. There came a time when the devices were satisfactory, and Fay actually attached one to the rudder of a ship to make sure that his adjustments were correct. The next move was to obtain explosives. Fay's prejudice against bombs placed in a ship's hold was that they rarely succeeded in sinking the craft; seventy or eighty pounds of high explosive detonated at the stern of a vessel, however, would blow the rudder away and not only cripple the ship but would probably burst a hole in the stern, mangle the screw, and split the shaft.
