VI. — Eepobt of the Committee to investigate the Fossili- 

 FEROUS Deposits at Kikmington, Linoolnshike, and at 

 various localities in the East Eiding of Yorkshire. 

 Chairman, Mr. G. W. Lamplugh ; Secretary, Mr. J. W. 

 Stathee.^ 



IT has only been found possible during the present year to 

 complete the investigation of the deposits at Kirmington and 

 Great Limber, but it is hoped in the future to extend operations to 

 Bielbecks and several other sections that require further elucidation. 



Kirmington Section. 



The work on this important section, which was begun last year, 

 has now been carried to a successful conclusion ; and the results 

 show that in some respects this section has no known parallel in 

 English drift sections. It will be remembered that, as described 

 in last year's report, a brickj'ard is worked at this place in a mass 

 of warp or clay containing estuarine shells, with a fresh-water bed at 

 its base, and that this deposit is overlain by a bed of coarse flinty 

 shingle, above which in one part of the pit there is found a few feet 

 of red stony clay believed to be a boulder-clay. The boring last 

 year proved the presence of a glacial clay at some depth beneath the 

 warp. The chief object of our investigation has been to discover 

 the relationship of the fossiliFerous warp to the Glacial Series, and 

 to carry the boring through the superficial deposits to the chalk, 

 which was not reached last year. 



During June of the present year a new boring was carried out 

 under the personal supervision of the Chairman and Secretary, with 

 the assistance of Mr. G. W. B. Macturk. Mr. Villiers, well engineer, 

 of Beverlej', undertook to put down the boring, and the Committee 

 desire to express their indebtedness to him for the ready manner in 

 which, at considerable personal inconvenience, he met their wishes 

 as to the time and conditions of the work. 



In order to secure a section in another part of the pit, the site of 

 the new boring was fixed at a point 80 yards north-east of last 

 year's boring. Although at the spot chosen the warp used for 

 brickmaking had been excavated to a depth of 5 feet below the level 

 of its base at the former site, this material was passed through in 

 the new boring to a further depth of 3 feet, so that its base is here 

 8 feet below its position in the former boring. The total depth 

 attained by the new boring, combined with the height of the open 

 section, was 96 feet, or 41 feet lower than was reached last year. 

 The surface of the chalk lay much deeper than was anticipated, and 

 the borings seem to prove that the surface features of the locality 

 are not due to the presence of chalk, as hitherto supposed, but that 

 the rising ground has been formed by the erosion of a thick and 

 complex mass of drift.
