Suggested on the Thames by the sight of one of those floating mills that used to be seen there. This I noticed on the Surrey side between Somerset House and Blackfriars Bridge. Charles Lamb was with me at the time; and I thought it remarkable that I should have to point out to 'him', an idolatrous Londoner, a sight so interesting as the happy group dancing on the platform. Mills of this kind used to be, and perhaps still are, not uncommon on the Continent. I noticed several upon the river Saone in the year 1799, particularly near the town of Chalons, where my friend Jones and I halted a day when we crossed France; so far on foot: there we embarked, and floated down to Lyons.
