The case of this offender has attracted considerable attention, from the scene of his death being described with accurate fidelity in Sir Walter Scott's novel of "The Heart of Mid-Lothian." John Porteous was born of indigent parents near the city of Edinburgh; and he served his time as an apprentice to a tailor. Having worked at his trade for some time, he was married to the cast mistress of the late Lord Provost of Edinburgh, who settled upon them a sum of 500_l._; but our hero, being a man addicted to the pursuit of pleasure, soon ran through his money, and his wife was in consequence obliged to apply to her old friend, the provost, to make some other provision for them. In Edinburgh there were three companies of men, in number twenty-five each, who were employed to keep the peace, and perform the general duties of a police force. An officer was appointed to each of these companies (whom they styled captain) with a salary of eighty pounds a year, and a suit of scarlet uniform; and a vacancy happening by the death of one of these captains, the provost immediately appointed Porteous to fill up the place. The latter soon distinguished himself by a show of great daring; and if a riot occurred in the city, he was generally chosen by the magistrates to suppress it. On these occasions, however, he would frequently behave with great violence and cruelty, so that he failed in obtaining that respect and attention which were so peculiarly necessary for a person in his situation. The circumstances attending the condemnation and death of Porteous were as follows:--Two fellows named Wilson and Robertson, who were daring smugglers, having been found guilty of a very serious breach of the revenue laws, were sentenced to die; and a strong feeling existing in their favour among the people, it was apprehended that it was very possible that an attempt might be made to rescue them from custody. Robertson, however, made his escape before the period arrived for his execution, by taking advantage of an opportunity afforded, by a custom which then prevailed, of taking the condemned criminals to church under the care of the city guards; and although Porteous was instantly despatched in search of him, his inquiries were in vain, and the criminal afterwards made good his flight to Holland. On the following Wednesday the execution of Wilson was appointed to take place, and a temporary gallows was erected in the Grass-market, the prisoner being ordered to be conducted there by fifty men, under the command of Porteous. Upon the representations of the latter, five companies of the Welch Fusileers were ordered to be in readiness in the Lawn-market to prevent any sudden outbreak; but no disturbance arising, the prisoner finished his devotions, ascended the ladder, and after having been turned off, continued hanging the usual time. The hangman then went up the ladder to cut him down; but a stone struck him on the nose, and caused it to bleed.
