The most of their time they spent about the real business in hand. They took care to have the windows of their room in the boarding house heavily curtained to keep out prying eyes, and here, under a student lamp, they spent hours over mechanical drawings which were afterward produced in evidence at the trial of their case. The mechanism that Fay had conceived was carefully perfected on paper, and then they confronted the task of getting the machinery assembled. Some of the parts were standard—that is, they could be bought at any big hardware store. Others, however, were peculiar to this device and had to be made to order from the drawings. They had the tanks made by a sheet-metal worker named Ignatz Schiering, at 344 West 42nd Street, New York. Scholz went to him with a drawing, telling him that it was for a gasolene tank for a motor boat. Scholz made several trips to the shop to supervise some of the details of the construction and once to order more tanks of a new size and shape.
At the same time Scholz went to Bernard McMillan, doing business under the name of McMillan & Werner, 81 Centre Street, New York, to have him make special kinds of wheels and gears for the internal mechanism of the bomb, from sketches which Scholz supplied. At odd times between June 10th and October 20th McMillan was working on these things and delivered the last of them to Scholz just a few days before he was arrested.
In the meanwhile, Fay was taking care of the other necessary elements of his scheme. Besides the mechanism of the bomb, he had to become familiar with the shipping in the port of New York, and he had to get the explosive with which to charge the bomb. For the former purpose he and Scholz bought a motor boat—a 28-footer—and in this they cruised about New York harbour at odd times, studying the docks at which ships were being loaded with supplies for the Allies and calculating the best means and time for placing the bombs on the rudder posts of these ships. Fay finally determined by experience that between two and three o’clock in the morning was the best time. The watchmen on board the ships were at that hour most likely to be asleep or the night dark enough so that he could work in safety. He made some actual experiments in fastening the empty tanks to the rudder posts, and found that it was perfectly easy to do so. His scheme was to fasten them just above the water line on a ship while it was light, so that when it was loaded they were submerged and all possibility of detection was removed.
The getting of explosives was, however, the most difficult part of Fay’s undertaking. This was true not only because he was here most likely to arouse suspicion, but also because of his relative lack of knowledge of the thing he was dealing with. He did know enough, however, to begin his search for explosives in the least suspicious field, and it was only as he became ambitious to produce a more powerful effect that he came to grief.
The material he decided to use at first was chlorate of potash. This substance in itself is so harmless that it is an ingredient of tooth powders and is used commonly in other ways. When, however, it is mixed with any substance high in carbons, such as sugar, sulphur, charcoal, or kerosene, it becomes an explosive of considerable power. Fay set about to get some of the chlorate.
But it is now time to get acquainted with Fay’s fellow conspirators, and to follow them through the drama of human relationships that led to Fay’s undoing. All these men were Germans—some of them German-Americans—and each in his own way was doing the work of the Kaiser in this country. Herbert Kienzle was a dealer in clocks with a store on Park Place, in New York. He had learned the business in his father’s clock factory deep in the Black Forest in Germany and had come to this country years ago to go into the same business, getting his start by acting as agent for his father’s factory over here. After the war broke out he had become obsessed with the wild tales which German propaganda had spread in this country about dum-dum bullets being shipped back for use against the soldiers of the Fatherland. He had brooded on the subject, had written very feelingly about it to the folks at home, and had prepared for distribution in the United States a pamphlet denouncing this traffic. Fay had heard of Kienzle before leaving Germany, and soon after he reached New York he got in touch with him as a man with a fellow feeling for the kind of work he was undertaking to do.
One of the first things in Fay’s carefully worked-out plan was to locate a place to which he could quietly retire when his work of destruction should be done—a place where he felt he could be safe from suspicion. After a talk with Kienzle he decided that Lush’s Sanatorium, at Butler, N. J., would serve the purpose. This sanatorium was run by Germans and Kienzle was well known there. Acting on a prearranged plan with Kienzle, Fay went to Butler and was met at the station by a man named Bronkhorst, who was in charge of the grounds at the sanatorium. They identified each other by prearranged signals and Fay made various arrangements, some of which are of importance later in the story.
Another friend of Kienzle’s was Max Brietung, a young German employed by his uncle, E. N. Brietung, who was in the shipping business in New York. Young Brietung was consequently in a position to know at first hand about the movements of ships out of New York harbour. Brietung supplied Fay with the information he needed regarding which ships Fay should elect to destroy. But first Brietung made himself useful in another way.
Fay asked Kienzle how he could get some chlorate of potash, and Kienzle asked his young friend Brietung if he could help him out. Brietung said he could, and went at once to another German who was operating in New York ostensibly as a broker in copper under the name of Carl L. Oppegaard.
It is just as well to get better acquainted with Oppegaard because he was a vital link in Fay’s undoing. His real name was Paul Siebs and for the purpose of this story he might as well be known by that name. Siebs had also been in this country in earlier days and during his residence in Chicago, from 1910 to 1913, he had gotten acquainted with young Brietung. He, too, had gone back to Germany before the war, but soon after it began he had come back to the United States under his false name, ostensibly as an agent of an electrical concern in Gothenburg, Sweden, for the purpose of buying copper. He frankly admitted later that this copper was intended for re-export to Germany to be used in the manufacture of munitions of war. He did not have much success in his enterprise and he was finally forced to make a living from hand to mouth by small business transactions of almost any kind. He could not afford a separate office, so he rented desk room in the office of the Whitehall Trading Company, a small subsidiary of the Raymond-Hadley Corporation. His desk was in the same room with the manager of the company, Carl L. Wettig.
