In their next undertaking the company was raised to its full strength by the accession of John Brown _alias_ Humphry Moore, whose previous experiences in England eminently qualified him to take an important part in such criminal enterprises. Brown appears to have been spending the autumn in Stirlingshire, but his visit was suddenly brought to a close in September on his banishment from that county by the Justices of the Peace for a theft committed by him within their jurisdiction. This was a more boldly conceived robbery than the gang had yet attempted--no less than the theft of the silver mace belonging to the University of Edinburgh. The Deacon, in the course of those walks with Smith, in which healthful exercise was combined with an eye to business, “carried” the latter “to the College Library, where, having observed the mace standing, Brodie said that they must have it.” Ainslie was accordingly sent to see where the mace was usually kept, and reported that it was in the Library, where the others had seen it. Accordingly, on the night of 29th October, 1787, the quartet proceeded to the University. “Having got access at the under gate, they opened the under door leading to the Library with a false key, which broke in the lock; and thereafter they broke open the door of the Library with an iron crow, and carried away the College mace.” The magistrates offered a reward of ten guineas for a discovery of the thieves, but without success. The mace was forthwith despatched to the accommodating Tasker, of Chesterfield, at the appropriate address of the “Bird in Hand,” and the macer thereof knew it no more. Brown appears entitled to the credit of planning the next robbery, and took a leading part in its execution. In those days the merchants of Edinburgh usually resided above their business premises, and the key of the shop was hung on the inside of the door--a habit highly appreciated by the Deacon’s little band. Brown brought to Smith the key of a shop belonging to one John Tapp, which, he said, also opened the door of that gentleman’s house; and Smith, having cast a professional eye over same, assured him “there was nothing in it.” Thereafter, one evening about Christmas time, between nine and ten o’clock, Brown dropped in upon John Tapp, whom he detained in his shop over a friendly and seasonable bottle. His associates, meanwhile, opened the house door with a false key and rifled the good man’s repositories, making off with “eighteen guinea notes, and a twenty shilling one, a silver watch, some rings, and a miniature picture of a gentleman belonging to Tapp’s wife, which picture they broke for the sake of the gold with which it was backed.” One wonders if Mrs. Tapp mentioned the loss to her husband. These valuables accompanied the mace to Chesterfield, where John Tasker _alias_ Murray seems to have driven a brisk, though illegitimate, trade, along with a letter to him, written by Brown in Smith’s name, arranging for their disposal.
