"The Duke is acquainted with no Frenchman whatever. I cannot cultivate the acquaintance of the few with whom I am acquainted, as I cannot bring them to our house, and am not always at liberty to go to theirs. The life which I led at Glasgow, was a pleasureable dissipated life in comparison of that which I lead here at present. I have begun to write a book, in order to pass away the time. You may believe I have very little to do. If Sir James would come and spend a month with us in his travels, it would not only be a great satisfaction to me, but he might, by his influence and example, be of great service to the Duke."[228:1] There is little doubt that the book he had begun to write, was the "Wealth of Nations:" and we have here probably the earliest announcement of his employing himself in that work. On the 21st of October, he writes from Toulouse, stating that the letters of introduction had reached him, and that his noble pupil was well received. He says, "Our expedition to Bourdeaux, and another we have made since to Bagneres, has made a great change upon the Duke. He begins now to familiarize himself to French company; and I flatter myself I shall spend the rest of the time we are to live together, not only in peace and contentment, but in great amusement." Amidst the multiplied attractions of Paris, Hume's thoughts were often turned to his native city, and the circle of kind friends and admirers he had there left behind him. Such reminiscences of home doings as are contained in the following letters, would doubtless ensure his warm attention. On 1st July, Blair writes: Robertson has, of late, had worse health than usual, which has somewhat interrupted his studies. He talked once of a trip to France this season; but his want of the language is so discouraging, as seems to have made him lay aside thoughts of it for the present. It will be a twelvemonth more, I suppose, before his Charles V. shall see the light. I dined this day with Sir James Macdonald, on whose praises I need not expatiate to you. Much conversation we had about you; and a great deal I heard of your flourishing state. You write concerning it yourself, like a philosopher and a man of sense. The first splendour and eclat of such situations soon loses its lustre, and often, as you found it, is burdensome. Ease and agreeable society are the only things that last and remain; and these, now that you are quite naturalized, and have formed habits of life, I imagine you enjoy in a very comfortable degree. The society at Paris, to one who has all your advantages for enjoying it in its perfection, is, I am fully convinced, from all that I have heard, the most agreeable in the whole world. Our education here is at present in high reputation. The Englishes are crowding down upon us every season, and I wish may not come to hurt us at the last.[229:1]
