122 LOAVER OOLITIC EOCKS OF ENGLAND : 
The following section at Haresfield Beacon was examined 
under the guidance of Mr. S. S. Buckman, who has published a 
detailed account of it* :

The division between the zone of Ammonites opalinus (Cephalopoda 
Bed) and overlying beds is from a palaentological point of view indefinite. 
Mr. Buckman includes beds 2 and 3 in the sub-zone of Ammonites 
striatulus. Belemnites are abundant in the Cephalopoda Bed. 
The Cotteswold Sands, and traces of the Cephalopoda Bed, 
were exposed in a lane-cutting west of Edge, and south of the 
Horsepools. The sands here contain very fine mealy beds, that, 
according to Mr. W. C. Lucy, were formerly used for cleaning 
silver. 
The Lower Limestones were exposed in a quarry near by, and 
again further north of the Horsepools. At the latter place the 
beds were much tilted, with appearances of " terminal curvature " 
on top. Here we find sandy, shelly, ferruginoun, and oolitic lime- 
stones, with rolled pebbles of oolite, and occasionally small quartz 
pebbles, as pointed out many years ago by Strickland. Annelide 
borings occur in different layers, and there is a marked band with 
ramifying ferruginous markings, like the bed seen at the base of 
the Frith section, and resembling the Great Oolite "Dagham 
Stone." (See p 286.) Mr. Lucy, who has described these beds, 
considers that the quartz grains may have been derived from the 
older rocks of the Forest of Dean. In the Huddingknoll quarry, 
at Horsepools, the conglomeratic Oolite is known as the " Dapple 
Bed " ; it contains tiny quartz pebbles, and pebbles of oolite, and 
is from 9 inches to 1 foot thick.t 
The Lower Freestone, Oolite Marl (6 feet), and Upper Free- 
stone are shown on Quar hill to the south of the Horsepools, 
where the beds are quarried for building-stone, and burnt for 
lime. Freestone is largely worked on Painswick Hill. The 
stone-beds are somewhat shattered, and consist of pale oolite 
with alternate layers of darker oolite. The stone, although 
reckoned a good weatherstone, does not last well if placed 
directly on the ground.
