SOME ESSEX WELL-SECTIONS. 49
Kelvedon.—Mr. Fuller's Bravery, by the bridge. 1887.
Tube-well, made and communicated by Messrs. Isler, and from an
account published by G. F. Beaumont, Essex Naturalist,vol. 1, p. 189.
88 feet above Ordnance Datum.
Water rose 6 feet above the ground.
The great thickness of Boulder Clay in this section is remarkable.
Can it be that some part assigned to this may be really London Clay ?
It is hard also to understand the beds below the blue clay. The
top foot of sand may be the basement-bed of the London Clay
(presuming that the blue clay belongs to that formation, and not to
the Reading Beds). From the other beds, down to the flints, being
all sand, one cannot fix the division between the Reading and the
Thanet Beds.
Littlebury.—Two borings in the village. 1887.
Made and communicated by Mr. G. Ingold.
1. In the middle of the village, where the road to Saffron Walden
branches off from the high road. (About 157 feet above Ordnance
Datum [? 155]). Abandoned.
