Commencing thus in one of the prettiest parts of the most picturesque suburbs of London, it flows from one to the other, right through the chain of the Highgate Ponds, fed by several rills, the first being near the Hampstead end of Millfield Lane--which is, by some, regarded as its source. From the lower pond it crossed the Highgate Road, and, for some distance, it ran parallel with it, although a little way eastward. It again crossed the Highgate Road not far from its junction with the Kentish Town Road, the course of which it followed, until it came to Hawley Road, where it was joined by a sister brook, whose source was the pond in the Vale of Health at Hampstead, flowing from which, it was fed by a brooklet, over which the abortive viaduct of Sir Thomas Marion Wilson's construction is carried. It ran into, and through, the Hampstead Ponds, which end at the lower east heath, near Pond Street (a locality easily recognized when once any one has seen St. Stephen's Church, Haverstock Hill, one of the most beautiful churches in London). These ponds are immortal, if they needed immortality, as the very first page of "Pickwick" gives an entry in the Transactions of the Pickwick Club: "_May 12, 1827._ Joseph Smiggers, Esq., P.V.P., M.P.C., presiding. The following resolutions unanimously agreed to-- "'That this Association has heard read, with feelings of unmingled satisfaction, and unqualified approval, the paper communicated by Samuel Pickwick, Esq., G.C., M.P.C., entitled, "Speculations on the Source of the Hampstead Ponds, with some observations on the Theory of Tittlebats"; and that this Association does hereby return its warmest thanks to the said Samuel Pickwick, Esq., G.C., M.P.C., for the same.'" Its memory is still retained in the Fleet Road. On its way through Kentish Town it passed through a purely pastoral country, such as we, who know the district only as covered with houses, can hardly reconcile with existing circumstances. The Guildhall Collection relating to the Fleet River, is very rich in water-colour drawings and pen-and-ink sketches of undoubted authenticity, and from them I have selected what, in my opinion, are the most suitable for this work.[16] From the above, and this view of Highgate, so late back as 1845, we can fairly judge of the pleasant scenery which existed almost at our doors--before the iron roads brought population, which begat houses, which destroyed all rusticity, leaving bricks and mortar on the site of verdant meads, and millions of chimneys vomiting unconsumed carbon and sulphur, in the place of the pure fresh air which once was dominant. [Illustration: THE FLEET, KENTISH TOWN. _Circa_ 1837.] Here we see the Fleet running its quiet course--and the other sketches bear witness to its rurality.
