28 PROCEEDINGS COTTESWOLD CLUB 1907 
From the field near Old-Green Barn a fine view was obtained 
of the distant escarpment of the Chalk. 
In the small field at Far-Hill Barn the Members completed their 
studies of the Inferior-Oolite geology of the district. They saw the 
rubbly C/ypeus-Grit in an old quarry, and a spring flowing off the 
Upper-Lias clay only a few feet lower down. 
By the side of the road three-quarters of a mile south by west of 
Fyfield is a disused quarry showing the basement-beds of the Great 
Oolite. Bed 1 must be paralleled with the Ostrea- and Rhynchonella- 
Bed of the section near Lower Swell. 
QUARRY NEAR FYFIELD 
Thickness in 
Feet inches 
1. Marl, yellowish and greyish, crowded with ; 
fragments of Ostrea Sowerbyi, Lycett, O. 
costata, Sow., UO. gregaria, Sow., Pecten (of 
P. vagans-type), Rhynchonella concinna 
(Sow.), Zerebratula maxillata, Sow., and 
echinoid-radioles. The marl is oolitic, and 
at the base are pebbles of oolitic limestone 
(bored chiefly by Lzthophag?, and encrusted 
with Osérea, sp. indet., and Berenicea) and 
rolled fragments of coral; seen 4 6 
2. Limestone, brownish, oolitic ; seen 12 ro) 
The next stopping place was at a quarry now abandoned, at the 
turning of the road to Tangley. The section has been described 
by Dr Callaway in the ‘* Geological Magazine,’" more with the object 
of drawing attention to the locality than of explaining the phenomena. 
Mr Richardson read portions of Dr Callaway’s paper. Dr Callaway 
hints at the clays here being Boulder Clays, and speaks of one of the 
two kinds he noticed as ‘ clay with northern erratics.” 
TTANGLEY SECTION 
(Record by L. Richarpson) Thickness in 
Feet inches 
1. Soil and subsoil; brown earthy, mixed with 
some clay from the bed below. Pebbles of 
rock, chiefly foreign to the district, such as 
quartz, quartzite, chert, quartzose grits, flints, 
etc. 
2. Tough, bluish-green, clay, oolitic in places, 
that has entered fissures in the subjacent rock, 
and spread out frequently along the bedding- 
planes. Imbedded in it at the base are 
nodules of a hard brown limestone, with a 
conchoidal fracture and frequently ferru- 
ginous. In these nodules are numerous 
gastropods (most probably species of Pseze- 
domelania) 43 2 ° 
3. Limestone, whitish, oolitic; Astarte sp., an 
echinoid: seen. : 6 fo)
