But before the express agent left the car Mooney told him that he wanted to place a package of marked bills in the safe. It might happen, by some accident, that the bandits attacking the train would get the best of it. In such event the package of marked bills would serve in tracking them down. He said this precaution had been determined upon by the Department in all cases. He produced an envelope—a brown manila envelope—sealed and stamped with red wax, and handed it to the express agent. The agent squatted down by the safe, opened it quickly, and put the envelope in among the other packages; then he closed the safe and locked it. This device gave Mooney the combination to the safe. He was standing close beside the express agent, stooping over with the envelope in his hand, so that it could be placed in the safe when the door was open, and he was therefore able to observe precisely what turns were made on the dial. For one with the skill of this extraordinary man, a glance was enough. When the express agent had swung the door back, Mooney knew every detail of the combination precisely. The man now left the car. Mooney fastened the door and proceeded at his leisure. He had explained to the sheriff that the small black leather bag which he carried contained handcuffs and weapons for his men. But it in fact contained a variety of quite different articles. He now opened it and sat down before the safe. The bag contained drills which Mooney had intended to use if the safe proved to be equipped with a modern time lock; as it was, these implements were not required. It also held a plumber’s candle, a tube of liquid glue, and a bundle of newspapers. He opened the safe without any difficulty whatever, for he had the combination directly from the express agent. Inside of the safe were a number of sealed packages in large envelopes. These envelopes were not only sealed with the gummed-down flap, but they were also sealed with wax. Mooney removed all of them. He lighted the plumber’s candle and very carefully held the wax seals close to the flame until they were soft enough for him to slip a knife blade under them. When the wax seals on the packages were all thus softened and lifted up without being broken, he opened the envelopes by rolling the point of a pencil carefully along under the flap. There were quite a number of these envelopes, all consigned to one bank and, while they all contained new currency, the men were astonished to discover that this currency was in small bills. The whole of it was in one-and two-dollar bills. There was not a bill of any larger denomination in the whole consignment. It was possible, of course, if these men were acting on information, that the persons forwarding that information to them knew this train would carry a consignment of money but did not know the value of that consignment. They may have estimated the value of it by its bulk.
