Having once nibbled, Evans was not long in biting at the bait thus adroitly held before him. He consented to be introduced to Perry, who shrewdly showed him what an easy matter it would be for a man who knew the secrets of safe-makers and could locate weak banks, to make a great deal of money, without danger to himself.
"Why," said Perry, "you can make more in one night with us, without any one's suspecting it, than you can make in a year working for these safe-people."
The result was that Evans, in consideration of fifty thousand dollars, finally agreed to provide some means of opening the Yale lock which barred the robbers from the coveted treasure at Elmira.
Perry, in great delight, hurried back to Elmira, and reported his success to Dunlap and Scott. In order to bring Evans to Elmira in a way not to excite suspicion, a letter was written to the company he served, containing a tempting proposition regarding the purchase of safes. Evans was at once sent to Elmira to look after the matter. He stopped at the Rathbone House, where he was waited upon by Scott, with whom he concerted a plan of operations. Scott was to slip a thin piece of wood into the lock at night, so that the lock would not work. Then, as Evans's presence in the city had been made known, it was hoped that he would be called upon, as an expert in difficult locks, to find out what was the matter. This would give him an opportunity to secure an impression of the key. The plan worked only too perfectly; and within twenty-four hours the conspirators were able to pass in and out of the Young Men's Christian Association rooms as they pleased, without the knowledge of any one.
It now remained, in order to achieve the robbery, to dig down into the vault—an immense task, for which the constant presence in Elmira of the whole gang was necessary. It was also necessary that their presence should not be noticed, and to that end a woman from Baltimore, who had been associated with one of the gang in previous undertakings, came on to Elmira and took a house in the suburbs, giving out that she was the wife of a man whose business kept him traveling most of the time. The house was simply furnished, and every day, for the benefit of the neighbors, the woman made a great pretense of sweeping the steps, cleaning the windows, and busying herself about the yard in various ways. Meantime, inside the house, in careful concealment, the members of the gang were living—Scott, Dunlap, "Red" Leary, Conroy, and Perry. They never went out in the daytime, and they left the place at night so cautiously, going one at a time, that, although they lived here for six weeks, their presence was never suspected.
Every night they gathered in the rooms of the Young Men's Christian Association after the young men had gone home, using their false keys to obtain admission; and they remained there hours at a time, doing what would ordinarily be the noisiest work; but their movements were so cautious and well planned that their presence in the building was never suspected. Every night the carpet and flooring were taken up, and, after they had finished their excavations, were carefully relaid. Tons of masonry and heavy stone were removed, shoveled into baskets, and carried up to the roof of the opera-house, adjoining the bank building, where there was small chance of the debris being discovered. Thus the unwearying rascals worked downward through the layer of railroad iron, and at last found themselves separated from the inside of the vault by only the plate of steel. Success seemed within their very grasp, when an unforeseen accident spoiled everything.
One day the president of the bank, Mr. Pratt, was surprised, on entering the vault, to find the floor sprinkled with a fine white dust. An investigation was made, and the whole plot was uncovered. The members of the gang, however, got word in time, and all managed to escape except Perry, who was convicted of attempted burglary and sent to the Auburn prison for five years.
Undisturbed by the failure, Scott and Dunlap proceeded to scour the country again in search of another bank suited to their operations, and in February, 1874, notified the gang, which now contained some new members, that they had "found something to go to work at" in Quincy, Illinois. The attack on the Quincy bank was made in very much the same way as the attack on the bank at Elmira. The Baltimore woman again rented a house which afforded shelter and concealment to the men; access was obtained to rooms over the vault by false keys, as before; the flooring was taken up and put down every night without exciting suspicion; the masonry was removed, the iron plates of the vault were penetrated, and, finally, one night Scott and Dunlap were able to lower themselves through a jagged hole into the money-room beneath.
It now remained to force open the safes inside the vault; and to accomplish this the robbers used, for the first time in the history of safe-wrecking in America, what is known as the air-pump method, which had been devised by Evans, and carefully explained by him to Scott and Dunlap. Evans's employers were at this time introducing a padding designed to make safes more secure; and Evans had hit upon the idea of introducing powder into the seams of a safe-door by an air-pump, in the presence of a possible customer, in order to impress him with his need of the new padding. Evans himself was not present at the breaking open of the Quincy bank, and he had nothing to do with the robbery beyond furnishing instruction and the air-pump. Scott and Dunlap did the work.
As a first step, all the seams of the safes formed by the doors were carefully puttied up, save two small holes, one at the top and one at the bottom. Then, at the upper hole, Scott held a funnel filled with fine powder, while Dunlap applied the air-pump at the hole below. By the draft thus created, the powder was drawn into all the interstices between the heavy doors and the frames of the safes. Then a little pistol, loaded simply with powder, was attached near the upper hole, and, by a string tied to the trigger, discharged from a safe distance above. There were several attempts made before a complete explosion was effected; but finally the safes were blown open and their contents secured, the robbers making good their escape with one hundred and twenty thousand dollars in money and about seven hundred thousand dollars in bonds. No part of this money was ever recovered by the bank, nor were any of the gang captured at this time. The securities were, however, afterward sold back to the bank. Indeed, so cleverly had the whole affair been managed that no suspicion fell upon either Scott, Dunlap, or any of their associates.
