PROCEEDINGS OF THE 
Field Meeting, 14th May, 1887. 
WATFOED AND BUSHEY. 
The object of this meeting was to examine sections of the Chalk 
and overlying Eocene beds in the neighbourhood of Bushey under 
the direction of Dr. John Morison, E.G.S. 
The chalk-pit near Bushey Station was first visited, Dr. Morison 
drawing attention to the lines of flints which indicate the Upper 
Chalk, and to the cavities called “ pockets ” or “ pipes ” filled with 
clay and pebbles from the Eocene beds above, which have taken the 
place of the chalk dissolved away. He was about to give an ex¬ 
planation of this process, which has frequently been alluded to in 
the Society’s ‘ Transactions,’ when a workman in charge of the pit 
interposed, objecting to the intrusion of the visitors, apparently 
oblivious of the fact that geologists consider they have a perfect 
right to invade any one’s property in pursuit of their study, but he 
was eventually appeased by the purchase of a few fossils he had 
obtained from the Chalk. 
The Bushey brickfield was then visited, Dr. Morison stating that 
it showed a good section of the Lower Eocene beds. Above was 
the London Clay of a dark chocolate-brown colour, and of great 
tenacity; below this was the basement-bed of sandy clay with dark 
flint-pebbles, and peculiar fossils ; and under this again were the 
"Woolwich and Reading Beds, consisting here of mottled clays and 
gravels almost unfossiliferous, though elsewhere they yielded fossils 
which in some places were marine, in others estuarine, and in 
others freshwater, showing great alternations of conditions during 
the deposition of the beds. 
Crossing the -fields towards Watford Heath, a pit in the London 
Clay was inspected, and then a brickfield by the side of Oxhey 
Lane, where the Reading Beds are again exposed, and show a marked 
difference from the same beds as seen at Bushey for such a short 
distance between them. 
A pleasant walk again across the fields brought the party to 
Haydon Hill, where Mr. and Mrs. Attenborough most kindly pro¬ 
vided tea, and, after the conservatory and grounds had been visited, 
a field-path was taken to Bushey Station and Watford. 
Ordinary Meeting, 24th May, 1887, at Hertford.
