He had, however, prepared an Appendix, containing some suggestions as to the best means of securing the strong rooms of banks, and other places, and also a chronological list of patents for improvements in locks, since the establishment of the first patent law, in the reign of James I., together with a list of those persons who had received prizes from the Society of Arts, for various improvements in secure fastenings. It was a well-known fact, that an unsuccessful attempt to rob a bank was scarcely ever heard of, the anticipated booty being so considerable, that the burglars could afford to spend considerable time in devising complete and effective plans. Indeed they frequently spent months in examining the locality, and in obtaining information, when, if no chance of success appeared, the enterprise was quietly abandoned. In many country banks, great carelessness was shown, both in regard to the quality of the locks, and in the custody of the keys. A good plan, sometimes adopted, was to have a bolt extending from a room on the second, or third story, which after traversing the back of the iron door of the strong room, was let into a socket in the top, and sometimes down into the bottom cill of the door ; in some cases, the room fixed upon was the bedroom of the manager, so that the bolt could only be raised, or lowered, with his knowledge.(Fig. 8.)
