80 NOTES ON TREE TRUNK WATERPIFES. exact dates, but is sure that there were a few wooden pipes existing, and in working order, "well into the Forties." On 24th September, is a letter signed E. A. Armstrong, who states that "some years ago," when watching the taking up of wooden water-pipes in Fleet Street, in the company of Mr. George Pollock, then King's Remembrancer, Mr. Pollock remarked that he well remembered seeing wooden pipes "not taken up, but laid down." On 25th September, two letters on this subject appeared, in the first, signed Grant Richards, the writer states that he remembers seeing wooden pipes taken up in Great Marlborough Street in 1899 or 1900. He evidently inclines to think that they were then being replaced by iron pipes. But most persons interested in these ancient wooden pipes have noted that they are often to be seen in excavations for various purposes in streets of a certain age, long after their disuse for water supply. For, when found, they seem to have no value for any practical pur- pose, being too thoroughly wet even for firewood. On the other hand, their usually very slight antiquity is likely to prevent them from being thought worthy of preservation in a museum. Another letter in The Times of 25th September is signed "Edward J. Renaud." The writer describes the construction of the wooden pipes and mentions the three excellent examples of them now to be seen in the Guildhall Museum. He adds that, the New River being completed, "its water first flowed into the Pentonville Reservoir on 29th September 1613." Wooden pipes were, he states, then used, at first oak, then sycamore, "by 1810 we find elm employed, but between that year and 1820 iron pipes were slowly substituted." He also mentions the rights which "the new River Company's charter gave them to cut trenches across any estate to carry these pipes." The latest letter on this subject appeared in The Times of 26th September, and is from Mr. G. F. Pollock, who is mentioned in Mr. E. A. Armstrong's letter of the 24th. He says:—"I certainly saw wooden pipes being laid down in the early thirties of last century. Being in my 93rd year, I can easily remember this." He adds that in the 27th Vol. of Rees' Encyclopaedia. title 'Pipe," the prejudice against iron pipes, owing to the belief that they would contaminate the water, is mentioned. Mr. Pollock's statement that he certainly saw wooden pipes laid down (for use) in the early thirties of last century is a very interesting addition to our knowledge of them.
