After 1800 Wilberforce seems in great measure to have cut himself loose from society that he considered frivolous; and to have used the extraordinary influence he possessed over his friends to endeavour to induce them also to forsake the world of fashion. The long letter which follows is from Lord Calthorpe (a relation of Barbara,[29] Wilberforce's wife), who had been strongly advised by Wilberforce not to spend a Sunday with the Duchess of Gordon in Scotland. Lord Calthorpe writes in great chagrin at having neglected the good advice of his mentor, had found the warnings against her fascinations very necessary, and had had the mortification of seeing her go to sleep while he read Leighton's "Commentary" to her. It would be of interest to know what were the "full and useful directions for public speaking" for which Lord Calthorpe is grateful to Wilberforce.

"Kinrara,
"September 2, 1801, Saturday.

"My dear Sir,—I have just evinced a proof of want of vigilance and self-discipline which vexes me so much that I am endeavouring to find relief from my vexation by telling it to you, as it is a satisfaction to me to think that you will pity me, in spite of the neglect of your advice, which I have betrayed. After having had the carriage at the door to leave this place (the Duchess of Gordon's) in order that we might spend to-morrow quietly, about twenty miles off, I have suffered myself to be persuaded to stay here till Monday. O how subtle are the devices of the enemy of our peace, and how weak our natural means of defence; the real cause of my falling into this temptation is now plain enough, but the shadow of delusion that for a moment imposed upon me was the idea of having some serious conversation with the Duchess, when we were likely to be almost alone, and which company has hitherto given me but little opportunity for; and this I was weak enough to indulge in spite of more sober convictions and the advice of Mr. Gorham and other objections, and I am just awakened to see the extent of my folly, conceit, and wilful depravity, by finding that we are to have no chance of having my imagination gratified, as Sir Wm. Scott has written word that he is coming to-morrow, and the delight with which the Duchess welcomed the intelligence has opened my eyes to my sottishness in thinking her sincere in her wish that I might pass a Sunday with her. I cannot conceive a scene more calculated to excite feelings of devotion and to expose worldly vanities than this spot, which is quite lovely, yet here I have found how strongly the world may engage the affections; there is something in the Duchess that pleases, although against the judgment (perhaps a little in the way of Falstaff), and makes her entertaining even when she is the subject of melancholy reflections; indeed, I feel how necessary your warnings against her fascinations were; she talked a great deal about her friend Wilberforce, and threatens you with a letter about me, and told me all my faults which she intended to report to you; I have not spent a Sunday (for it is now over) with so much self-reproach since I came into Scotland. She seems to be on the same kind of terms with religion as she is with her Duke, that is, on terms of great nominal familiarity without ever meeting each other except in an hotel or in the streets of Edinburgh. She fell asleep on Sunday while I was reading to her part of Leighton's Commentary and awoke with lively expressions of admiration at what she had not heard; she talks of setting off for Ireland in a few weeks and of going to London afterwards, so I hope that she will do no harm at Edinburgh next winter. I left Kinrara on Monday and got to Blair at night; I found there more of ancient stateliness than I have yet seen, and I think the Duke of Athol is fond of keeping it up; he has some very fine scenery about him there, and his other place Dunkeld, which is twenty miles off, is perhaps more beautiful although less wild and magnificent. Sir W. Scott (whom I never see without thinking of you) is on a visiting tour, and went from Blair with Lord Frederick Campbell to Lord Melville's and from thence goes to the Duke of Argyle's and Montrose's back to Edinburgh; he was very tortuous and amusing. I have written this by scraps, and am ashamed to have been so long about it. Many thanks for your last letter, and especially for your kindness in giving me such full and useful directions for acquiring a talent for public speaking; I will endeavour, as far as I am able, to do justice to them, and I expect to find your technical lines of great service to me. I believe that the plan of religious reading which you mention is the best, and surely I have no small encouragement to pursue it, and when I am so great a gainer by its beneficial effects in your case. I spent yesterday at Lord Mansfield's, at Scoone, where the Kings of Scotland used to be crowned; the old palace has been pulled down, and a very large Gothic house built upon its site. I hope you are enjoying health and quiet where you are, and every other blessing. Give my kindest remembrance to Mrs. W.

"Believe me, my dear sir,
"Affectly yours,
"Calthorpe.

"You shall hear from me again."

Wilberforce's influence with Pitt was also known to Maria, Duchess of Gloucester.[30] It will be remembered that Henry William, third son of George II. (created Duke of Gloucester in 1764), married Maria, Dowager Countess of Waldegrave, in 1766. This lady writes to Wilberforce, hoping that through his "mediation with Pitt" a regiment of dragoons may be given to her son Lord Waldegrave.

The Duchess of Gloucester to Mr. Wilberforce.

"Genoa, February 4, 1786.

"Sir,—Although you did not succeed in one of my requests to Mr. Pitt, you were more successful in the other; and for that I return you my thanks. I did not very much flatter myself that Mr. Pitt would add a place to what Lord Waldegrave at present possesses, indeed a regiment is almost the only addition he is likely to gain; and as Mr. Pitt has expressed his satisfaction in the marks of favour already received from the King, may I hope, through your mediation, that Mr. Pitt will be so good as to remind His Majesty how very acceptable a regiment of dragoons will be to Lord Waldegrave. If Lord Waldegrave was distressed from his own extravagance I would not trouble Mr. Pitt, but my daughter's father left his brother a clear estate which is now encumbered as much as if the late Lord Waldegrave had come to the title and estate, at twenty-four, instead of forty-four. The Duke of Grafton's reconciliation with his son is now so old a story that I only mention it as a fact that I am sensible gives you pleasure? Mr. Pitt is so much attached to Lord Euston, that I must take part in an event that I know gives him so much pleasure. I hope Lord Lucan will suffer the match to take place, but till it is over I shall have my doubts. If Mrs. Wilberforce and your sister are in town will you give them my best compliments. Sophia and William are both as tall as yourself.
