Vol. 59.] WELL-SECTIONS IN SUFFOLK. 33 



/ 



1. On some Well-Sections in Suffolk. Ey William Whitakek, 

 B.A., F.R.S., F.G.S. (Read December 3rd, 1902.) 



Some 170 well-sections in Suffolk were noticed in thirteen Geological 

 Survey Memoirs up to the year 1893. Many of these were shallow, 

 but many were of considerable depth. Few of the accounts had 

 been published before. 



Two years later, seventeen fresh sections were described in a 

 paper on some Suffolk well-sections, 1 and since then four others 

 have been noticed in various publications. 



As notes of thirty-one more have accumulated ; as there is no 

 opening for the printing of these, either in a Survey Memoir or in 

 the publication of a local society (for there is no such publication) ; 

 and as some of them have points of considerable geological interest, 

 it is hoped that I may be forgiven for bringing matters of local 

 detail (such as the following sections of twenty borings) before the 

 Geological Society, which, as a rule, is hardly the proper place for 

 them. 



Though ready to take a somewhat extended view of a remark 

 made by a former President, that papers of local character would 

 find a more appropriate birth near the place of their conception, 

 yet I think it better that such papers (at all events my own) should 

 be born rather than strangled in embryo. 



The object of this paper is to show how greatly our knowledge 

 may be added to by wells or borings, and how sometimes these give 

 results that could not have been expected. 



WOODBRIDGE. 



If there is a place in Eastern Suffolk where one might reasonably 

 expect to be able to foretell the depth to the Chalk, through some 

 thickness of overlying beds, within a small limit of deviation, that 

 Xjlace is Woodbridge ; for we have published records of wells or 

 borings at eight places in that town and in the adjoining village of 

 Melton, which reach the Chalk with no great variation of depth, 

 with one exception, and that only from considerable difference in 

 the height of the ground. 



A summary of the results may be given in a tabulated form, as 

 follows, with the addition of the level of the Chalk-surface where it 

 can be given : —
