PROCEEDINGS, 
Excavation liad now been commenced between the two bridges 
which cross the line in this cutting. South of and close to the 
northern bridge the section showed, in descending order, soil 
1 ft. 6 ins., clayey pebble-gravel 5 or 6 ft., London Clay 2 or 3 ft., 
brown loam 2 ft., band of black flint-pebbles 3 ins., brown loam 
1 ft. shown ; total about 12 to 14 ft. 
Opposite the northern end of Sandpit Wood the cutting had 
been commenced at a lower level, 5 or 6 ft. above the railway 
lines, well exposing the Leading clay, mottled green and red. 
Along a higher level, opposite the southern end of Sandpit 
Wood, a good exposure of the basement-bed of the London Clay 
was seen. The pebble-band was 3 ins. thick, with many pebbles 
2 to 3 ins. long, and below it was brown loam of the basement- 
bed, 6 ft. seen but evidently 7 to 8 ft. thick down to the lower 
pebble-band. Here a good specimen of Panopsea intermedia 
was found. Two feet below the upper pebble-band a 6 in. hard, 
calcareous, concretionary band containing fossils was traced for 
several yards, and two feet above that pebble-band was about 
3 ft. of brown loam with fossils. Hear Little Oxhey Lane 
bridge the loam passes up into 3 or 4 ft. of sandy clay, with 
patches of sand but without fossils, and above this, close to 
the bridge, was seen 4 or 5 ft. of decomposed pale-grey and 
brown clay. 
From observations made at this and the previous visit to the 
Bushey cutting, confirmed by examinations made by Mr. Kidner 
and Mr. Woodhead, it was determined that the line of outcrop 
of the Leading Beds would be approximately indicated by a line 
drawn from the south-eastern corner of a small plantation on the 
west side of the line, opposite Sandpit Wood, across the railway 
to the middle of the wood where it broadens out eastward. 
The meeting concluded with tea at the same place as at the 
previous meeting.
