The other personal question arose also out of circumstances which have their counterpart in Smith’s own history.  Professor William Rouet, Professor of Ecclesiastical and Civil History, made an engagement in 1759 to travel abroad as tutor with Lord Hope, the eldest son of Lord Hopetoun; but when Lord Hopetoun wrote requesting leave of absence for Professor Rouet, the Senate by a majority refused to grant the request.  Smith was one of that majority, and took an active part in the subsequent transactions arising out of their decision.  Rouet persists in going abroad in the teeth of the refusal, and the University by a majority deprive him of office for his negligence of duty.  The Crown, however, at first refuse to appoint a successor, on the ground of informality in the act of deprivation, and Lord Bute tells the Rector, Lord Erroll, that “the king’s orders” are that the business must be done over again de novo, or “else it may be of the worst consequences to the University.”  The University take the opinion of eminent counsel, Ferguson of Pitfour and Burnet of Mountbodie (Monboddo), and are prepared to face the consequences threatened, but are eventually saved the trouble by the resignation of Rouet in 1761.  Now in these transactions Smith seems to bear a leading part.  He was one of the small committee appointed to draw up answers to the protest tabled by the minority of the Senatus; it was to him Lord Erroll communicated the intimation of Lord Bute, though he was not then either Vice-Rector or Dean of Faculty; and it was he and Professor Millar who were sent through to Edinburgh to consult the two advocates.

Smith was probably on the best terms with Rouet himself, who was an intimate friend of David Hume and a cousin of their common friend Baron Mure, and it was not an uncommon practice for the Scotch universities at that period to sanction the absence of a professor on a tutorial engagement.  Adam Ferguson left England as tutor to Lord Chesterfield while he was Professor of Moral Philosophy at Edinburgh, and Dalzel resided at Oxford as tutor to Lord Maitland after he was Professor of Greek in the same University.  The Senate of Glasgow had itself already permitted Professor John Anderson to remain another winter in France with a son of the Primate of Ireland, when he was chosen Professor of Oriental Languages in 1756, and Smith had concurred in giving the permission.  But Anderson’s absence was absence to fulfil an already-existing engagement, like the absence granted to Smith himself in the first year of his own appointment, while Rouet’s was absence to fulfil a new one; and Smith, as his own subsequent conduct shows, held pluralities and absenteeism of that sort to be a wrong and mischievous subordination of the interest of the University to the purely private interest or convenience of the professors.  They had too many temptations to accommodate one another by such arrangements at the expense of the efficiency of the College; and his action both in Rouet’s case and his own is entirely in the spirit of his criticism of the English universities in the Wealth of Nations.
