Following the Atterbury plot of 1722 the earl of Orrery, one of the prominent English Jacobites, told James III that they must bend all their efforts ‘to lull the Government asleep and make them believe there are no further thoughts of designs against them’. Their efforts were never to be realized, for to the English government ministerial idleness where Jacobites were concerned was a luxury it felt it could not afford. By 1716 the government had been made too well aware of the threat this group presented to its position. Reversal could only be avoided through close vigilance and the early detection of plot and conspiracy. Their earlier experiences of attempted plots, near assassinations, foreign aid, open rebellion, and the inability to gauge the movement's strength, created in the ministers between 1715 and 1745 an almost pathological fear of a Stuart restoration. It was never to subside but only to increase with each passing year, reaching its climax during the administration of Robert Walpole. Dissatisfaction with the existing system under the Hanoverians and the presence of an alternative choice on the continent were two facts that could not be overlooked. Jacobitism as a rallying cry for the disaffected in England, Ireland, and Scodand was an obvious reality. Each ministry, in varying degrees, pursued what appeared to it to be the hideous, all-pervasive force of Jacobitism – a force that seemed to assume infinite proportions the less visible it was to the eye. Jacobites must be hunted out, their secrets penetrated, their plans squashed. The best evidence of this pre-occupation of the government with fear of a Stuart restoration lies in an examination of its methods of securing intelligence through the post office, the employment of spies, and personal interviews with the Jacobites themselves.
