became so well known, that no man, except such as were his nearest friends, and socii criminis, gave him any trust; and so little regard had he to his promises and vows, that it was observed and notorious, that if he was at any pains to convince you of his friendship, and by swearing and imprecating curses on himself and family to assure you of his sincerity, then, to be sure, he was doing you underhand all the mischief in his power."[17]

These characteristics must be viewed as proceeding from the pen of a partisan; nor can we wonder at the contrariety of opinion which prevails respecting any public man who proposes a great and startling measure. Honours, places, and a pension were showered down upon this most fortunate of ministers; and his career is remarkable as having been cheered by the favour of four sovereigns of very different tempers. In his early youth, after his return from his travels, the Duke of Queensbury was appointed a Privy Councillor of Scotland by Charles the Second. He held the same post under James the Second, but resigned it in 1688. The reserved and doubting William of Orange placed him near his person, making him a Lord of the Bedchamber, and captain of his Dutch guard; eventually he became Lord High Treasurer of Scotland, and—to abridge a list of numerous employments and honours—Lord High Commissioner of Scotland. So far had Queensbury's fortunes begun with the Stuarts and continued under the House of Orange. It appeared unlikely that the successor of William—she who in her first speech announced that her heart was "wholly English," to mark the distinction between herself and the foreigner who had sat on the throne before her,—would adopt as her own representative in Scotland the favourite of William; yet she continued Queensbury in that high station which it was believed none could fill so adequately in the disturbed and refractory kingdom of Scotland.[18]

During the early years of Queen Anne's reign, and in the season of his own comparative prosperity, the young Earl of Mar entered into his first marriage, at Twickenham, with Lady Margaret Hay, daughter of John Earl of Kinnoul. The wife whom he thus selected was the daughter of a house originally adverse to the principles of the Revolution. William Earl of Kinnoul, in the time of James the Second, had remained at St. Germains with that monarch. But the same change which had manifested the political course of Lord Mar, had been apparent in the father of Lady Margaret Hay. The Earl of Kinnoul was afterwards one of the Commissioners for the Union, and supported that treaty in Parliament; yet, when the Rebellion of 1715 commenced, this nobleman was one of the suspected persons who were summoned to surrender themselves, and was committed a prisoner to Edinburgh Castle. His daughter, the Countess of Mar, was happily spared from witnessing the turmoils of that period. Married in her seventeenth year, she lived only four years with a husband whose character was but partially developed, when, in 1707, she died at the age of twenty-one, having given birth to two sons. She was buried at the family seat at Alloa Castle, an ancient fortress, built in the year 1300, one turret of which still remaining rises ninety feet from the ground. Seven years intervened before Lord Mar supplied the place of his lost wife by another union.

His days were, indeed, consumed in public affairs, varied by the improvement of his Scottish estates, embellishing the tower of Alloa by laying out beautiful gardens in that wilderness style of planting which the Earl first introduced into Scotland.[19] He had the reward of seeing his efforts succeed, the gardens of Alloa being much eulogized and visited. This was by no means Lord Mar's only recreation; architecture was his delight, and he introduced into London the celebrated Gibbs, who, out of gratitude, eventually bequeathed a large portion of his fortune to the children of the Earl.[20] It is refreshing to view this busy and versatile politician in this light before we plunge into the depths of those intricate politics which form the principal features of his life.

It was during the year 1703 that a political association or club was framed consisting of the chief nobility and gentlemen of fortune and afterwards known by the name of the Squadrone Volante. They acquired distinguished popularity and influence by the patriotic character of the measures which they introduced into the Scottish Parliament; and by their professions of being free from any court interest, they gained the confidence of the country. They were firm friends of the Revolution party, great sticklers to the Protestant succession, forming a separate band distinct from the Whigs, yet opposed to the Cavaliers, or, as they were afterwards called, Jacobites. The power of the Squadrone was, in a great measure, the result of those jarring counsels in the Scottish Parliament, which only coalesced upon one theme,—independence of England—interference of "foreign" or English counsels, as they were termed. This combination was headed by the Duke of Montrose, the Marquis of Tweedale, and several other Scottish noblemen, to whom adhered thirty commoners.[21]

During the existence of this association, the celebrated "Queensbury affair," as it was usually called, involved the temporary disgrace of the Duke of Queensbury, and first brought to view those convenient doctrines of expediency which afterwards formed so marked a feature in the character of Lord Mar.

The "sham plot," as it is called by Jacobite writers, was a supposed intended invasion of Great Britain, disclosed to the Duke of Queensbury by Simon Fraser of Beaufort, afterwards Lord Lovat; whose very name seems to have suggested to his contemporaries, as it has since done to posterity, the combination of all that is subtle, treacherous, and base, with all that is dangerous, desperate, and remorseless in conduct.

This tool of the court of St. Germains came over from France, in company with John Murray, who was sent to watch his proceedings, and also to aid his object in procuring the promises of the most distinguished Highland chieftains to the furtherance of the projected invasion of England. The assistance of Captain Murray was conjoined on this occasion, the fidelity of that gentleman having been ascertained by the court of St. Germains; whilst there existed not a human being who did not instinctively distrust Beaufort: to Mary of Modena, who far more ardently desired the restoration of the Stuarts than her consort James, he was peculiarly obnoxious.

The exiled Queen's fears proved well founded, for no sooner had Beaufort landed in England, than he formed the scheme of converting this secret enterprise into a means of obtaining reward and protection from the Duke of Argyle, whose mediation with the Duke of Queensbury
