Smith did not reply to either of these letters till the 13th of September, when he writes from Dalkeith House, where he has gone for the home-coming of the Duke and Duchess of Buccleugh. After expressing his mind in the plainest terms about the bishop with whom Hume had the tussle--"He is a brute and a beast," says Smith--he goes on to bespeak Hume's favour for a young cousin of his who happened to be living in the same house with Hume in London, Captain David Skene, afterwards of Pitlour, who was in 1787 made inspector of military roads in Scotland. Be so good (he says) as convey the enclosed letter to the Count de Sarsfield. I have been much in the wrong for having delayed so long to write both to him and you. There is a very amiable, modest, brave, worthy young gentleman who lives in the same house with you. His name is David Skeene. He and I are sisters' sons, but my regard for him is much more founded on his personal qualities than upon the relations in which he stands to me. He acted lately in a very gallant manner in America, of which he never acquainted me himself, and of which I came to the knowledge only within these few days. If you can be of any service to him you could not possibly do a more obliging thing to me. The Duke and Dutchess of Buccleugh have been here now for almost a fortnight. They begin to open their house on Monday next, and, I flatter myself, will both be very agreeable to the People of this country. I am not sure that I have ever seen a more agreeable woman than the Dutchess. I am sorry that you are not here, because I am sure you would be perfectly in love with her. I shall probably be here some weeks. I could wish, however, that both you and the Count de Sarsfield would direct for me as usual at Kirkaldy. I should be glad to know the true history of Rousseau before and since he left England. You may perfectly depend upon my never quoting you to any living soul upon that subject.--I ever am, dear sir, most faithfully yours, ADAM SMITH.[207]
