6 ft.; with 2 to 8 ft. of clay and pebbles proved below, but not 
seen, resting on the Chalk. For a length of 50 ft. or more 
these beds were seen to be covered with Pleistocene gravel 
14 to 15 ft. in thickness, and southwards the section extends for 
about 50 ft. from this gravel. 
That these are Eocene beds in situ the Director said was 
shown by their situation on the .200 ft. contour-line, being the 
position of the Beading Beds at Bushey; by the proximity of 
the Chalk, and by their facies being of the Beading type for 
this district, having thick beds of pebbles in the lower part of 
the series. They appear to have been deposited within a hollow 
depression in the Chalk, having a ridge of chalk more or less 
around it, and thus were able to resist the agencies of denuda¬ 
tion, afterwards becoming covered with gravels of a much later 
age probably laid down by the Chess and the Grade, between 
which rivers, near their junction with the Colne, they occupy 
high ground. 
From Long Valley Wood the party proceeded to Gonville, 
Croxley Green, the residence of Sir Hugh Beevor, who showed 
a collection of palseolitlis and simpler flint tools mostly obtained 
by himself and Dr. Ingleby Oddie from these pits and others at 
Mill End, Bickmansworth. The collection includes such un- 
symmetrical forms as push-planes, borers, knives and scrapers, 
hammers, strikers, and anvils, which, from their primitive form, 
are termed “ Eolithic.” Some of the Palaeolithic implements 
are very fine specimens. Dr. Oddie also showed a sarsen, 
2^ ft. in length and roughly oval in shape, from the Croxley pits. 
After according thanks to Sir Hugh Beevor and Dr. Oddie, 
on the proposition of Mr. George Potter, a Vice-President of 
the Geologists’ Association, and Mr. Gi. W. Lamplugh, President 
of the Herts Society, the party proceeded to Bickmansworth, 
where tea was had at the G-range Hotel.
