CARBONIFEROUS LIMESTONE SERIES.

Corner. As pointed out by Prof. Lloyd Morgan, it cuts the 
strata somewhat obliquely, with the result that as it is followed 
westward lower and lower strata are brought in contact with one 
another till the fault dies out. In the Avon Valley S 2 is 
brought over D 2, in the field to the W. of Beggar's Bush Corner 
the Candnia-Oolite (C 1) is brought over Si, which is much crushed 
and veined. Upper Farm (Hill Farm) stands on the Caninia- 
Oolite, and a second development of this horizon is seen in an 
old quarry about 300 yards W. of the Farm. The repetition is 
clearly due to the passage of the fault, which, I believe, here 
brings the Laminosa Dolomite (lower C 1) over the Caninia- Oolite 
(Upper C 1). I attribute the strong contortion of the Z-beds in 
the old quarry to the E. of the road and about 250 yards S. of 
Yew Tree Cottage, and the discordant dips just W. of the road, 
to the fault, and have not found traces of it further W. Prof. 
Lloyd Morgan has also alluded to the disturbed condition of the 
strata as indicated by the confusion of dips at this locality. 
Cross Faults. — The strata are further traversed by a series of 
cross faults (see map). Those to the E. of Nash House shift the 
outcrop northward, while those further W. shift it southward. 
IV. — Description of the Exposures. 
(1) The Cleistopora (K) Beds. 
The only complete section of these beds in the whole area is 
in the Avon Valley, where the exposures were fully described 
by Vaughan. Elsewhere the beds are only seen in occasional 
outcrops of the harder bands, especially of the Bryozoa-bed. 
The line of outcrop of the K-beds is throughout marked 
by a deep depression which passes just to the E. of Abbot's 
Leigh, then S.W. to Yew Tree Cottage, and westward pass the 
Failand Golf Course to Failand Farm. There a fault shifts 
the outcrop northward, and the depression extends from Funny 
Row along Ox House bottom to Failand Hill House. Here a 
second fault shifts the outcrop northward, and the depression 
may be followed to Racecourse Farm, where a third fault shifts 
the strata yet further to the N., and the depression extends 
through Charlton House Deer Park and Moat House to end near 
Nash House, where the Pennant Sandstone is faulted against 
the Carboniferous Limestone series. 
The exposures may be quickly described. Small quarries in 
the Bryozoa-bed having the usual character of a red crinoidal 
limestone occur on both sides of the road leading through Fish 
Pond Wood, Abbot's Leigh. The western exposure shows also 
crystalline and fossiliferous limestone below the Bryozoa-bed. 
The same band of limestone, here coarsely oolitic, was exposed 
in 1917 in a trench dug at a point near the edge of the wood 
J mile N.E. of the church, in connection with a volunteer camp 
held in the Old Park, Abbot's Leigh. Thin-bedded limestone 
with bryozoa and Camarotcechia mitcheldeanensis was thrown
