202 MINERAL WATERS AND MEDICINAL SPRINGS OF ESSEX. and was kept so for some years. A writer, speaking of this spring in 1834, 100 years after it was enclosed, says 'many persons now living recollect its being enclosed, but it is now unenclosed and nearly filled with mud, which, and the water, are both of a most nauseous smell, but tasteless. Some bricks lately taken out are turned black to the middle of them. The smell strongly resembles that issuing from a smith's trough in which hot iron is plunged. This, probably, is testimony to its mineral qualities.' " No doubt it [the water] is highly purgative and diuretic, as it contains sulphate of magnesia and muriate of soda, but it has never been properly analysed. Had the locality been in its favour and patrons been found, it might, with a little skill, have proven as efficacious as any celebrated spring. It is now a somewhat difficult job to find it, though still in existence." At the present day, the well, though totally neglected for its mineral and medicinal properties, is well-preserved and protected by a triangular wooden fence (fig. 2).32a This is said33 FIG. 2—THE MINERAL SPRING O.N TYLER'S COMMON, UPMINSTER (from a drawing by H.

Mr. Walter Crouch, F.Z.S., of Wanstead, who visited the well on 21st June 1890, in company with Messrs. William and H. A. Cole, writes34 :— " Pieces of the dried earth—a kind of iron clay—which was . . . thrown 32a The well is shown, though not named, on Chapman and Andre's Map of Essex (1777) but is neither shown nor named on the 6-inch Ordnance Map. 33 See Mr. W.
