72 ON TREE-TRUNK WATER-PIPES. Wicken Bonant, near Saffron Walden, in 1869. In each case the mischief was clearly shown to be traceable to a water supply from shallow wells in the gravel on which the houses stood. At Terling some water was also obtained from the Ter where it flowed through the village; and at Page Green Water- works supplied some of the houses. But the shallow-well water was evidently the most popular at Page Green, and we are told that the inhabitants were surprised to find that it was supposed to have anything injurious in it, "and amused at its being analysed." This popular preference for shallow-well water to that from waterworks, in a London suburb, in the year 1865, enables us to realise the still stronger feelings of the same kind which must have prevailed in rural districts up to that time, and have tended to prevent any considerable use of wooden water-pipes in small country towns after their disuse in London and other great centres of population. Essex is a county in which we might expect to find a special abundance of survivals of old wooden appliances of all kinds. It is one of the most uniformly well-wooded of districts, has many wooden village spires, abounds with wooden houses, and has (as Matthew Arnold notes in his Letters) an "ancient" look generally. Finding that Chelmsford, though on a gravelly site, was in 1771 using pipes to convey water from the Burgess Well to the Conduit in the Market Place, I wrote to Mr. F. Chancellor, F.R.I.B.A., &c., asking him if they were, or, so far as he knew, ever had been, of wood. However, he was good enough to inform me that as the supply came from a spring only 650 yards away, the pipe was of lead. He was well aware of the former use of tree-trunk pipes, and remembered seeing many disinterred some years ago in Bishopsgate Street, when a new iron main was being laid; at the time when the Great Eastern Terminus was at Shoreditch. But, as regards Essex, Mr. Chancellor replied:—"I never remember seeing anything of the kind in the county; the nearest approach to it is the old Tree- Pump, which used to be very common in this county, and I daresay there may be one or two left." Though, from one point of view, tree-pumps and tree-pipes are things which might naturally be expected to flourish together in the same district, from another they tend rather to be mutually exclusive. For where the water supply of town or village is
