To conceal the true nature of their operations they hired a small
building on Main Street and put a sign over the door announcing
themselves in business as “The Riverside Garage.” They added
verisimilitude to this scheme by buying a second-hand car in bad
condition and dismantling it, scattering the parts around the room
so that it would look as if they were engaged in making repairs.
Every once in a while they would shift these parts about so as to
alter the appearance of the place. However, they did not accept any
business—whenever a man took the sign at its face value and came in
asking to have work done, Fay or Scholz would take him to a nearby
saloon and buy him a few drinks and pass him along by referring him to
some other garage in the neighborhood.
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
gasoline 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 Center Street, New York, to have him
make a special kind 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 harbor 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 feasible 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.
