"I have always been unwilling to mention Marr, but I find myself indispensably engaged at present to let my Scots friends know that I have withdrawn my confidence entirely from him, as I shall be obliged to doe from all who may be any ways influenced by him. This conduct is founded on the most urgent, strongest, and most urging necessity, in which my regard to my faithfull subjects and servants have the greatest share. "What is here said of Marr, is not with a view of its being made publick, there being no occasion for that, since, many years ago, he put himself under such engagements, that he could not serve me in a publick capacity, neither has he been publickly employed by me." To this it was answered, by the confidential friend to whom the remarks were addressed, "It is some time agoe since your friends here had doubts of the Earl of Marr; and thence it was that I was directed to mention him in the manner I did in my last two letters, it being matter of no small moment to us to know in whom wee might confide thorowly, and of whom beware,--especially when a person of his figure was the object."[167] Affairs were in this state; the Chevalier distrustful of Lord Mar, and devoted to his rival, Colonel Hay; the Princess heading an opposite faction, nominally commanded by Mrs. Sheldon, but secretly instigated by Lord Mar; when, in 1722, the conspiracy of Atterbury was discovered by the British Government. The Earl of Mar was at that time in Paris, and Lord Carteret who was at the head of affairs in England, remembering the Earl's former negotiations with Lord Stair, dispatched a gentleman to Mar, with instructions to sound that nobleman as to his knowledge of the plot. Lord Mar happening to be in Colonel Dillon's company when the messenger reached Paris, and soon divining after one interview the nature of the embassy, it was agreed between him and Dillon that they would do James's cause a service by leading the British Government off the right scent. They therefore drew up, in conjunction, an answer to Lord Carteret. What was the nature of that reply,[168] does not appear; but its result was such as to cast upon Lord Mar a degree of odium far greater than that which he had incurred in Lord Stair's business. He was accused by Atterbury with having, on that occasion, written such a letter as had been the cause of his banishment; with having betrayed the secrets of the Chevalier St. George to the British Government; and of several other charges of "base and treacherous practises, discovered by the Bishop of Rochester, that the like had scarce been heard of, and seem'd to be what no man, endued with common sense, or the least drop of noble blood, could perpetrate; and that the King's friends were at a loss in not knowing what credit to give to such reports, tho' they apprehended the worst, from the directions he had lately given of having no correspondence with Mar or his adherents, from whom he had withdrawn all confidence."
