In 1825, this was the first open view nearest London of the ancient River Fleet: it was taken during the building of the high-arched walls connected with the House of Correction, Cold-bath-fields, close to which prison the river ran, as here seen. At that time, the newly-erected walls communicated a peculiarly picturesque effect to the stream flowing within their confines. It arrived thither from Bagnigge-wells, on its way to a covered channel, whereby it passes between Turnmill-street, and again emerging, crosses Chick-lane, now called West-street, near Field-lane, at the back of which it runs on, and continues under Holborn-bridge, Fleet-market, and Bridge-street, till it reaches the Thames, close to the stairs on the west side of Blackfriars-bridge. The bridge, whereby boys cross the stream in the engraving, is a large iron pipe for conveying water from the New River Company’s works, to supply the houses in Grays-inn-lane. A few years ago, the New River water was conducted across this valley through wooden pipes. Since the drawing was made, the Fleet has been diverted from the old bed represented in the print, through a large barrel drain, into the course just mentioned, near Turnmill-street. This notice of the deviation, and especially the last appearance of the river in its immemorial channel, may be of interest, because the Fleet is the only ancient stream running into London which is not yet wholly lost to sight. The River Fleet at its source, in a field on the London side of the Hampstead ponds, is merely a sedgy ditchling, scarcely half a step across, and “winds its sinuosities along,” with little increase of width or depth, to the road from the Mother Red Cap to Kentish Town, beneath which road it passes through the pastures to Camden Town; and in one of these pastures, the canal, running through the Tunnel at Pentonville to the City-road, is conveyed over it by an arch. From this place its width increases, till it reaches towards the west side of the road leading from Pancras Workhouse to Kentish Town. In the rear of the houses on that side of the road, it becomes a brook, washing the edge of the garden in front of the premises late the stereotype-foundery and printing-offices of Mr. Andrew Wilson, which stand back from the road; and, cascading down behind the lower road-side houses, it reaches the Elephant and Castle, in front of which it tunnels to Battle-bridge, and there levels out to the eye, and runs sluggishly to Bagnigge-wells, where it is at its greatest width, which is about twelve feet across; from thence it narrows to the House of Correction, and widens again near Turnmill-street, and goes to the Thames, as above described.
