ADDITIONAL NOTES ON TREE-TRUNK WATER-PIPES. 237 which had been taken out of the excavations there, on the side of the road near the Piccadilly front of the Museum. During some months of the present year (1903) excavations have been in progress in the roadway of London Street, Greenwich, for the laying down of electric tram-lines. On August 18th my wife informed me that some tree-trunk pipes had been exposed. On visiting the spot I saw some about 3 feet beneath the surface. A good specimen of one of the shorter pipes was sent up to my house, through the kind intervention of Mr. G. Jones, 21, London Street. I am also much indebted to Mr. Knock, 54 and 56, London Street, who showed me some good specimens which he had caused to be placed in his garden : and to Mr. E. J. Pearce, of 92, London Street, who informed me of the discovery of some more wooden pipes a few days later. All were found near the junction of London Street with Royal Hill. Mr. Jones was specially interested in these pipes, because he remembered seeing similar ones in the year 1870 in the neighbourhood of New North Road and in High Holborn, when the New River Company was laying down larger main pipes there. He also remembers hearing from relatives that a large number of these pipes used to be in the gardens of the Round House, Clerkenwell. The Round House was demolished between 50 and 60 years ago. I am much indebted to my friend, Mr. R. O. Heslop, F.S.A., &c., of Newcastle-on-Tyne, for the following interesting details from the History of the Water Supply of Newcastle-on-Tyne, a pamphlet written in 1851 by D. D. Main, then Secretary of the Newcastle and Gateshead Water Company, and reprinted from the Newcastle Chronicle, 1851. After alluding to a scheme devised by Peter Morrys in 1580 for supplying the City of London with water, Main remarks that a similar project was suggested for Newcastle in 1697 by William Yarnold, an enterprising attorney from Oxfordshire, "who came before the mayor and made a proposal for supplying the town with good and wholesome water." He obtained an Act of Parliament (1698-9) and power "to break up the pavement of the streets, and to lay down pipes of lead or timber for the supply of the inhabitants." Yarnold constructed a small reservoir at Coxlodge, and laid down a four-inch wooden pipe from Coxlodge across the Moor, through the town of Newcastle,.
