The Canal, up to Holborn Bridge, was expensive to keep up, and as we saw, by the quotation from Ned Ward, it was next door to worthless. Meantime, sewage and silt played their work, as the stream was neglected, and, becoming a public nuisance, it was arched over, pursuant to an Act 6 Geo. II. cap. 22, entitled "An Act for filling up such Part of the Channell of _Bridewell Dock_, and _Fleet Bridge_, as lies between _Holborn Bridge_ and _Fleet Bridge_, and for converting the Ground, when filled up, to the use of the City of _London_." The works were begun in 1734 and was arched over and finished in 1735; but, as buildings are necessary for a market, it was not opened, as such, until Sept. 30, 1737. For nearly a century it remained a market for meat, fish, and vegetables, although, of course, the largest meat market was Newgate, as being near Smithfield; and for fish, Billingsgate, which still maintains its pre-eminence But in 1829 it was pulled down, in order to make a wider street from Holborn to Blackfriars Bridge; and this part of the Fleet was called, and now is, Farringdon Street. [Illustration: FLEET MARKET, FROM HOLBORN BRIDGE.] The Vegetable Market, for it had come to that only, was swept away, and a site found for it, nearly opposite the Fleet prison. It is still so used, but it is not much of a financial help to the City, as it only brings in an annual income (according to the last return I have been able to obtain) of between £700 and £800. It was thought that trade might be encouraged, and revived, if it were worthier housed, so what is now, the Central Fish Market, was erected; but, before the vendors of vegetables could enter into possession, a great cry had arisen as to the supply of fish to London, and the monopoly of Billingsgate, and the market was given over to the fishmongers. But it is not a success in a monetary point of view; is a great loss to the City, and, as a fish market, a very doubtful boon to the public. The Fleet Prison, which was on the east side of Farringdon Street, will be noticed in its place; and, as we have seen, the river was arched over from Holborn to Fleet Bridge, after which it still flowed, an open sewer, into the Thames.
