Charles Townshend adhered to his purpose about Smith with much more steadiness than Hume felt able to give him credit for. Townshend, it need perhaps hardly be said, was the brilliant but flighty young statesman to whom we owe the beginnings of our difficulties with America. He was the colonial minister who first awoke the question of "colonial rights," by depriving the colonists of the appointment of their own judges, and he was the Chancellor of the Exchequer who imposed the tea duty in 1767 which actually provoked the rebellion. "A man," says Horace Walpole, "endowed with every great talent, who must have been the greatest man of his age if he had only common sincerity, common steadiness, and common sense." "In truth," said Burke, "he was the delight and ornament of this house, and the charm of every private society which he honoured with his presence. Perhaps there never arose in this country nor in any other a man of a more pointed and finished wit, and (when his passions were not concerned) of a more refined and exquisite and penetrating judgment." He had in 1754 married the Countess of Dalkeith, daughter and co-heiress of the famous Duke of Argyle and Greenwich, and widow of the eldest son of the Duke of Buccleugh. She had been left with two sons by her first husband, of whom the eldest had succeeded his grandfather as Duke of Buccleugh in 1751, and was now at Eton under the tutorship of Mr. Hallam, father of the historian. On leaving Eton he was to travel abroad with a tutor for some time, and it was for this post of tutor to the Duke abroad that Townshend, after reading the _Theory of Moral Sentiments_, had set his heart on engaging its author.
