Book excerpt: Excerpt from Records of London Wells During the last few years an exceptionally large number of borings to obtain water have been made within the London area. This has been accompanied by an increasing number of enquiries at the Office of the Geological Survey. The information sought was scattered through a number of publications, and in many cases the sites of the older wells were not accurately known. It consequently became necessary to arrange the information in some more accessible form. For the purpose of recording the sites of the wells a series of the six-inch London County maps, specially printed with wide margins free from writing, has been placed in the Library for permanent reference. On the left margin of each map a list of the deep wells is entered, and on the right a list of the shallower bores and more important openings. Each map is divided into two-inch squares, lettered from north to south - a, b, c, &c., and numbered from west to east -1, 2, &c., to 9. The square within which a well is situated is thus shown by a letter followed by a number. In the marginal lists the letter and number are followed by the title of the well and a reference to previous publications in which the well has been described. The abbreviations used in these lists are explained on pp. 1 and 2. The second part of this Memoir consists of a Catalogue of published London Wells. It was found that not only was the information respecting the wells widely scattered, but. that the descriptions often failed to give many details, a knowledge of which is essential in questions of water-supply. These are supplied in the present work, and the sites of the wells have been more precisely determined than hitherto. The wells here dealt with arc all of considerable depth and, with a few exceptions, carried into the chalk. The third part of the Memoir consists of a list of the wells of which no account has hitherto been published, with such details as appear to he essential. In comparing the lists of old and new wells attention is at once drawn to a marked lowering of the water-level. Not only is the fall greater than was anticipated, but it has been taking place at an increasing rate during the last ten years. The present water-level in the older wells has been made the subject of special inquiry, and with rare exceptions the information has been willingly supplied and great assistance has been rendered by the large business-firms. The Borough Engineers and other officials have been specially obliging, not only sending a full account of the wells under their charge, but in many cases calling attention to the existence of other wells. We are greatly indebted also to the principal firms of Artesian Engineers who, in addition to other information, have often given the original water-level and the date when it was measured, thus enabling the extent and rapidity of the fall to be traced.
