The Duke of Devonshire lives near.

I often see his footmen lounging at the back gate, and the Duke of Wellington's house is not far off.

Such sights as I saw, my dear! It was as good as Punch, for there were fat dowagers rolling about in their red and yellow coaches, with gorgeous Jeameses in silk stockings and velvet coats, up behind, and powdered coachmen in front.

Smart maids, with the rosiest children I ever saw, handsome girls, looking half asleep, dandies in queer English hats and lavender kids lounging about, and tall soldiers, in short red jackets and muffin caps stuck on one side, looking so funny I longed to sketch them.
Rotten Row means 'Route de Roi', or the king's way, but now it's more like a riding school than anything else.

The horses are splendid, and the men, especially the grooms, ride well, but the women are stiff, and bounce, which isn't according to our rules.
