The three Irishmen were then pardoned; and the lord mayor having interested himself in their behalf, a subscription was opened, and they were enabled to return to their own country, and there to purchase small farms. GEORGE VAUGHAN, ROBERT MACKEY, AND GEORGE BROWN. CONVICTED OF A CONSPIRACY. While the lord mayor was detecting the "men of blood" in the city, the magistrates at Bow-street were not less meritoriously employed in tracing similar crimes to a police-officer, named Vaughan, and several others not immediately employed by the magistrates, but who were well known as loungers about the different offices. Several of these atrocious wretches were apprehended, and many revolting circumstances disclosed. George Vaughan, Robert Mackey, and George Brown, were tried at the Middlesex sessions, on the 21st of September 1816, on a charge of conspiring to induce William Hurley, Michael Hurley, William Sanderson, William Wood, aged thirteen, and Dennis Hurley, to commit a burglary in the house of Mrs. M'Donald, at Hoxton; and, by having them convicted of the fact, thereby procure for themselves the rewards given by parliament for the conviction of housebreakers. The case was clearly proved against the prisoners; and it appeared that through the instrumentality of one Drake, who had been an acting lieutenant in the navy, the dupes were employed to commit the burglary, and that on their proceeding to Mrs. M'Donald's house, the three prisoners came up and took them into custody. The prisoners being found guilty were sentenced to five years' imprisonment in the house of correction, and ordered at the conclusion of that time to find security for their future good behaviour. Vaughan was tried on a subsequent day for a robbery in the house of one James Poole, on the 16th of December 1815, and being found guilty was sentenced to be transported. JOHN CASHMAN EXECUTED FOR A FELONY COMMITTED AT THE SPAFIELDS' RIOTS. On the cessation of the protracted war which consigned Buonaparte to St. Helena, Great Britain found herself subject to those temporary domestic difficulties which always succeed a sudden return from hostility to peace. The revulsion was felt by nearly every individual in the kingdom; agriculture, trade, and commerce became, for the instant, almost torpid, and thousands of the labouring classes were thrown out of employment.
