We were very much surprised on Thursday last by the arrival of the Racoon, sloop of war, from Jamaica, with the duke of Manchester on board, who is come with the view of visiting the lions of Canada previous to his return to England; he is gone, attended by General Drummond, to see the falls of Montmorenci, and the general desires me to let you know that his grace intends leaving this in the stage on Tuesday morning for Montreal. The duke has no attendant except a Colonel Gold, _ci-devant militaire_; he appears to be very affable, and perfectly _sans façon_; he particularly requested that no compliments or ceremony of any kind might be shown him, and that he might be permitted to indulge his fancy by going about as he pleased. His grace is not likely to have many volunteer aides-de-camp, for he treated those who formed his suite yesterday to a walk of half a dozen hours in the sun at mid-day round the works, the towers, plains, &c.; and from which he did not appear to experience the slightest inconvenience, being in the habit, we are told, of taking similar rambles even in the West Indies. The duke will pay you but a very short visit, being limited for time, and anxious to make his tour as extensive as possible. He seems to like a glass of Madeira, and would match any of the Canadian tribe in smoking cigars; he walks about with one in his mouth at all hours in the day. He begs you will have the kindness to secure for him a boat and a good Canadian crew to proceed to Kingston, and to facilitate his progress from that place, inasmuch as it may be in your power to do so. I apprehend that the movement of the troops may very materially interfere with him, but the duke will not object to embarking with any of the detachments if no other vessel can be spared. _Colonel Baynes to Major-General Brock, at William Henry, Sorel_.
