When Hume arrived in France the first letter he wrote to any of his friends at home was to Smith. He had been only a week in the country, and describes his first experiences of the curious transformation he then suddenly underwent: from being the object of attack and reproach and persecution for half a lifetime among the honest citizens of Edinburgh, he had become the idol of extravagant worship among the great and powerful at the Court of France.

"During the last days in particular," he says, "that I have been at Fontainebleau I have suffered (the expression is not improper) as much flattery as almost any man has ever done in the same time, but there are few days in my life when I have been in good health that I would not rather pass over again.

"I had almost forgot in this effusion, shall I say, of my misanthropy or my vanity to mention the subject which first put my pen in my hand. The Baron d'Holbach, whom I saw at Paris, told me that there was one under his eye that was translating your Theory of Moral Sentiments, and desired me to inform you of it. Mr. Fitzmaurice, your old friend,[132] interests himself strongly in this undertaking. Both of them wish to know if you propose to make any alteration on the work, and desire you to inform me of your intentions in that particular."[133]

Hume's hope of their "not impossible" meeting in Paris was destined to be gratified sooner than he could have conjectured. A few days before Smith received this letter from Hume he had received likewise the following letter from Charles Townshend, intimating that the time had now come for the Duke of Buccleugh to go abroad, and renewing to Smith the offer of the post of travelling tutor to his Grace:—

Dear Sir—The time now drawing near when the Duke of Buccleugh intends to go abroad, I take the liberty of renewing the subject to you: that if you should still have the same disposition to travel with Him I may have the satisfaction of informing Lady Dalkeith and His Grace of it, and of congratulating them upon an event which I know that they, as well as myself, have so much at heart. The Duke is now at Eton: He will remain there until Christmass. He will then spend some short time in London, that he may be presented at Court, and not pass instantaneously from school to a foreign country; but it were to be wished He should not be long in Town, exposed to the habits and companions of London, before his mind has been more formed and better guarded by education and experience.

I do not enter at this moment upon the subject of establishment, because if you have no objection to the situation, I know we cannot differ about the terms. On the contrary, you will find me more sollicitous than yourself to make the connection with Buccleugh as satisfactory and advantageous to you as I am persuaded it will be essentially beneficial to him.

The Duke of Buccleugh has lately made great progress both in his knowledge of ancient languages and in his general taste for composition. With these improvements his amusement from reading and his love of instruction have naturally increased. He has sufficient talents: a very manly temper, and an integrity of heart and reverence for truth, which in a person of his rank and fortune are the firmest foundation of weight in life and uniform greatness. If it should be agreeable to you to finish his education, and mould these excellent materials into a settled character, I make no doubt but he will return to his family and country the very man our fondest hopes have fancied him.

I go to Town next Friday, and should be obliged to you for your answer to this letter.—I am, with sincere affection and esteem, dear sir, your most faithful and most obedient humble servant,

C. Townshend.

Lady Dalkeith presents her compliments to you.

Adderbury, 25th October 1763.[134]

Smith accepted the offer. The terms were a salary of £300 a year, with travelling expenses while abroad, and a pension of £300 a year for life afterwards. He was thus to have twice his Glasgow income, and to have it assured till death. The pension was no doubt a principal inducement to a Scotch professor in those days to take such a post, for a Scotch professor had then no resource in his old age except the price he happened to receive for his chair from his successor in the event of his resignation; and we find several of them—Professors Moor and Robert Simson of Glasgow among others—much harassed with pecuniary cares in their last years. Smith's remuneration was liberal, but nothing beyond what was usual in such situations at the time. Dr. John Moore, who gave up his medical practice in Glasgow a few years later to be tutor to the young Duke of Hamilton, got also £300 a year while actively employed in the tutorship and a pension of £100 a year afterwards.[135] Professor Rouet, who, as already mentioned, sacrificed his chair in Glasgow for his tutorial appointment, is said to have received a pension of £500 a year from Lord Hopetoun, in addition to a pension of £50 he received, in consideration of previous services of the same kind, from Sir John Maxwell; and Professor Adam Ferguson, who was appointed tutor to the Earl of Chesterfield on Smith's recommendation, had £400 a year while on duty, and a pension of £200 a year, which he lived to enjoy for forty years after, receiving from first to last nearly £9000 for his two years' work. Smith did almost as well, for with the pension, which he drew for twenty-four years, he got altogether more than £8000 for his three years' service.

This residence abroad for a few years with a competent tutor was then a common substitute for a university education. The Duke of Buccleugh, for example, was never sent to a university after he came back from his travels with Smith, but married almost immediately on his return, and entered directly into the active duties of life. It was generally thought that travel really supplied a more liberal education and a better preparation for life for a young man of the world than residence at a university; and it is not uninteresting to recall here how strongly Smith disagrees with that opinion in the Wealth of Nations, while admitting that some excuse could be found for it in the low state of learning into which the English universities had suffered themselves to fall:—

"In England it becomes every day more and more the custom to send young people to travel in foreign countries immediately upon their leaving school, and without sending them to any university. Our young people, it is said, generally return home much improved by their travels. A young man who goes abroad at seventeen or eighteen, and returns home at one-and-twenty, returns three or four years older than he was when he went abroad; and at that age it is very difficult not to improve a good deal in three or four years. In the course of his travels he generally acquires some knowledge of one or two foreign languages; a knowledge, however, which is seldom sufficient to enable him either to speak or write them with propriety. In other respects he commonly returns home more conceited, more unprincipled, more dissipated, and more incapable of any serious application, either to study or to business, than he could well have become in so short a time had he lived at home. By travelling so very young, by spending in the most frivolous dissipation the most precious years of his life, at a distance from the inspection and controul of his parents and relations, every useful habit which the earlier parts of his education might have had some tendency to form in him, instead of being riveted and confirmed, is almost necessarily either weakened or effaced. Nothing but the discredit into which the universities are allowing themselves to fall could ever have brought into repute so very absurd a practice as that of travelling at this early period of life. By sending his son abroad, a father delivers himself, at least for some time, from so disagreeable an object as a son unemployed, neglected and going to ruin before his eyes."[136]

Smith must have written Townshend accepting the situation almost immediately on receiving the offer of it, and he at the same time applied to the University authorities for leave of absence for part of the session. He does not as yet resign his chair, nor does he make in his application any formal mention of the nature of the business that required his absence; he merely asks for their sanction to some highly characteristic arrangements which he desired to make in connection with the conduct of his class by a substitute. On the 8th of November 1763, according to the Faculty Records, "Dr. Smith represented that some interesting business would probably require his leaving the College some time this winter, and made the following proposals and request to the meeting:-?

"1st, That if he should be obliged to leave the College without finishing his usual course of lectures, he should pay back to all his students the fees which he shall have received from them; and that if any of them should refuse to accept of such fees, he should in that case pay them to the University.
