Bed i8 is certainly Great Oolite : probably the top-bed of 
what Woodward would have called the “ White Limestone 
series.” Bed 19 is a very distinctive stratum on account of 
its non-oolitic nature and cream colour, but with a ” pinkish ” 
tinge. The limestones (22c) (23 ft. thick) below the ” Dagham 
Stone ” (226) are more evenly oolitic, and therefore a better 
freestone, than those above (22a). 
” Passage Beds.” — At 125 ft. down the yellowish oolitic 
limestones ended, and the grey and dark-grey — sometimes 
almost blackish — rocks commenced. Those down to 172 ft. 
6 ins., and therefore 47 ft. 6 ins. thick, are “ Passage Beds ” 
between the Great Oolite and Fullers’ Earth, 
Bed 23 is a well oolitic limestone. Its lower portion (23^)) 
is shown in Fig. i. Some geologists might feel disposed 
to group it with the Great Oolite, but its colour is similar to 
that of the ” Passage Beds.” It is 8 ft. thick, contains a 
yellowish zone — reminding one of bed 43 at Shipton Moyne — 
between 2 ft. 9 ins. and 4 ft. 4 ins. down, while the portion 
between 5 ft. 9 ins. and 6 ft. 9 ins. is ” sparry ” — just like the 
main portion of bed 42 at Shipton Moyne. 
Bed 24 — the marl composing which soon crumbled to 
pieces (hence the gap in the core — Fig. i) — shows that 
the ” Great Oolite limestones ” have been left. The impure 
limestones associated with the marls of bed 25, with their small 
white crinoid-ossicles, are similar to each other, with the 
exception of one bed { 2 '^b^), which is a very fine-grained lime- 
stone, sandy to the touch and 3 to 4 ins. thick. 
At 144 ft. a very massive bed (26) of a very light-grey, 
fine-grained limestone, sandy to the touch, was encountered, 
and one solid core 6 ft. 6 ins. long was drawn. It was this 
portion of the core that attracted the special attention of 
certain members of the Club on the occasion of their visit on 
September 25th, 1913d The top of the bed is waterworn 
and pitted with the crypts of Lithophagi. The lower 3 ft. 9 ins. 
(Fig. 2) is less pure limestone owing to an admixture of 
marl, and did not draw in one piece. In the bottom inch, 
which is shaly, small ” pisolites ” were abundant.
