Numerous were the plots which had been laid for the same purpose, and frequent were the proceedings which had been had upon complaints laid before the various courts of criminal justice in the kingdom, since the year 1715, when the rebellion first broke out; but the plan laid by Mr. Layer was one of those which gained the greatest degree of notoriety. This infatuated man had received a liberal education, and was a member of the society of the Inner Temple; but being impressed with the possibility of the success of a scheme for the dethronement of the existing monarch, and the elevation of the Pretender to the rank, to which it was contended that he was entitled, he made a journey to Rome, in order to confer with that prince upon the propriety of putting his design into execution, promising that he would effect so secret a revolution in England, that no person in authority should be apprised of the scheme until it had been actually completed.

But it was not until he had nearly given his jailers the slip, that this determination was carried into execution with effect; for it appears that the prisoner became convinced of the practicability of an escape from the room where he was confined, through an ale-house, which was situated at the back of the messenger's house, and resolved to make the attempt to procure his liberty. He therefore formed a rope of his blanket, and, dropping from the window of his apartment, he fell into the yard below, unscathed; but in his descent, he overset a bottle-rack, and from the noise which was caused,
