There are no memorials of the extent to which the river Fleet was anciently navigable, though, according to tradition, an anchor was found in it as high up as the Elephant and Castle, which is immediately opposite Pancras workhouse, and at the corner of the road leading from thence to Kentish-town. Until within these few years, it gave motion to flour and flatting mills at the back of Field-lane, near Holborn.[28]
That the Fleet was once a very serviceable stream there can be no doubt, from what Stow relates. The level of the ground is favourable to the presumption, that its current widened and deepened for navigable purposes to a considerable extent in the valley between the Bagnigge-wells-road and Gray’s-inn, and that it might have had accessions to its waters from other sources, besides that in the vicinity of Hampstead. Stow speaks of it under the name of the “River of Wels, in the west part of the citie, and of old so called of the Wels;” and he tells of its running from the moor near the north corner of the wall of Cripplegate postern. This assertion, which relates to the reign of William the Conqueror, is controverted by Maitland, who imagines “great inattention” on the part of the old chronicler. It is rather to be apprehended, that Maitland was less an antiquary than an inconsiderate compiler. The drainage of the city has effaced proofs of many appearances which Stow relates as existing in his own time, but which there is abundant testimony of a different nature to corroborate; and, notwithstanding Maitland’s objection, there is sufficient reason to apprehend that the river of Wells and the Fleet river united and flowed, in the same channel, to the Thames.
