58 SOME ESSEX WELL-SECTIONS.
Major Raban writes that on reaching the water-bearing beds
beneath the London Clay (which gave much trouble), from 434 to
460 feet down, the water-level in the War Department well at
Sheerness fell 17 feet.
The divisions of the Lower London Tertiaries are not clearly
marked. Perhaps the lower bed classed with the Blackheath Beds
may belong in part to the Woolwich Beds ; and the same may be
the case with the top sand classed with the Thanet Beds.
The divisions of the Chalk are still more doubtful.
