![KENT WATER SUPPLY. 2- Foratal, for Maidstone Waterworks Co., 1898. Trial-boring. Close to the Medway, about half a mile above Aylesford. Communicated by Mr. W. Ware, Engineer to the Company. (Rochester Naturalist, 1901.) (Notes from specimens in these brackets.) [Folkestone Beds, 129£ feet] Gravel ('Yellow sand (Brownish sand at 20. Light-brown sand at 25, 35 and 45, the middle one duller, the lowest lighter, all loose. Clayey dull light-brown sand at 51) Brown clay (very fine compact clayey sand) Grey sand (Rather fine loose sand at 55. Dull dark-greenish, slightly clayey compact sand at 67) Green sand and clay. (Dull grey compact sand, ? slightly clayey, at 80 and 90, the latter darker)... Green sand. (Brownish-grey sand, partly rather compact, but break- ing up readily at 100,110,120; and at 130 the like, grey. At 140 fine green-grey sand, in part slightly compacted, but breaking up readily ; some Glauconite grains) Rock. (Concretion of pyrites, a set of small balls, with wood, at 147£) [? Sandgate Beds] Black clay. (Very dark greyish clay sand or sandy clay at 150) f Rock (chert at 156^) Hassock. (Compacted, ? calcareous sand or soft stone, and stone, full of Glauconite grains at 157f) Rock Hassock Rock Rock and Hassock Blue clay Rock Clay Hard sand Clay Rock Sand I Rock Atherfield Clay] Sandy blue clay Hythe Beds, 71 feet] Thickness.

It must be noted that we have not the whole thickness of the Folkestone Beds here, the Gault not coming on above for some little distance northward. To the 129 feet of the section we must add not only the 19 feet taken up by Gravel, but some- thing more, making the total thickness of the Folkestone Beds, say, 160 feet, if the classification suggested in the section is right.](https://iiif.wellcomecollection.org/image/b28126737_0098.jp2/full/800%2C/0/default.jpg)
