Roebuck made some observation about agriculture. "Yes, sir," said the ploughman, "but in Sicily they had a different method," and he quoted Theocritus, to Roebuck's great astonishment. Among Smith's chief Edinburgh friends at this period was one of his former pupils, William Johnstone--son of Sir James Johnstone of Westerhall, and nephew of Lord Elibank--who was then practising as an advocate at the Scotch bar, but ultimately went into Parliament, married the greatest heiress of the time, Miss Pulteney, niece of the Earl of Bath, and long filled an honoured and influential place in public life as Sir William Pulteney. He was, as even Wraxall admits, a man of "masculine sense" and "independent as well as upright" character, and he devoted special attention to all economic and financial questions. It was Pulteney who in his speech on the suspension of cash payments by the Bank of England in 1797--in which he proposed the establishment of another bank--quoted from some unknown source the memorable saying which is generally repeated as if it were his own, that Smith "would persuade the present generation and govern the next." He quoted the words as something that had been "well said." Between him and Smith there prevailed a warm and affectionate friendship for more than forty years, and we shall have occasion again to mention his name. But I allude to him at present because a letter still exists which was given him by Smith at this period to introduce him, during a short stay he made in London, to James Oswald, then newly appointed to office at the Board of Trade. This is the only letter that happens to be preserved of all the correspondence carried on by Smith with Oswald, and while both the occasion of it and its substance reveal the footing of personal intimacy on which they stood, its ceremonious opening and ending indicate something of the reverence and gratitude of the client to the patron:--
