The robbery of the mail caused great excitement in Edinburgh so soon as it became known, and no long time elapsed before the perpetrators were in the hands of the authorities. The two men concerned in it proved to be James Clark _alias_ Alex. Stewart, and Robert Brown, formerly privates in the Foot Guards. No sooner had they got back to Edinburgh--where they had previously lodged--than they commenced to change some of the bank-notes taken from the mail-bag, and got the worse of drink; and being once suspected, the evidence soon accumulated and became strong against them. They were tried for the offence before the High Court of Justiciary in Edinburgh in November following, and being found guilty, were sentenced to be executed. This robbery would appear to have had the effect of stirring up the public mind to demand a means of conveying the mails between the two cities affording greater security; for an agitation immediately followed for the setting up of coaches or diligences to carry the mails between those cities. Owing, however, to difficulties and disagreements between the merchants and traders as to the hours of departure and arrival, and to wranglings over the particular route to be journeyed, the idea was abandoned, and the horse-post as of old was meanwhile continued. The robbery seems not to have been soon forgotten, however; for we find that towards the close of 1802 a proposal was made to enter into an agreement for the service with "an officer of the Mid-Lothian Cavalry, and master of the Riding Academy in Edinburgh," who offered to conduct and carry on the service in a masterly and military manner for an allowance of £450 per annum--the riders to be employed being none other than able and active dragoons. But in the nature of things such a mail service could not continue, and negotiations still proceeded for the employment of diligences--not resulting in success, however, until the year 1805, when the first mail-coach between Edinburgh and Glasgow was put upon the road. A somewhat similar attack upon a postboy was made in Yorkshire in the year 1798, when the rider's life was threatened by a highwayman single-handed, and the mails stolen from him. The case is interesting owing to the fact that traces of the robbery were obtained so recently as 1876, though at the period of its occurrence no trace of the highwayman or of his plunder could be discovered. The official account of the robbery, when it happened, was as follows:--
