over the ground again this autumn, what appeared to be new 
features presented themselves, which deserve at least a passing 
notice. 
The ordinary section presented in the larger quarries at 
Eggford and opposite Vallis Farm, in Vallis Vale, is a very 
familiar one, consisting of a bold escarpment of Mountain Lime- 
stone lying at a high angle, but in which the upturned edges 
of the strata have been planed down to a comparatively level 
surface, on which has been deposited unconformably a thin bed of 
Inferior Oolite. On entering the Vallis at Hapsford, however, 
and before reaching the great quarry worked for so many years 
at that end of the valley, the writer was attracted by some less 
prominent exposures of rock on the east side of the ravine, which 
being partly hidden by brushwood, had previously escaped his notice. 
The base of the section consisted, as in all the Vallis quarries, of — 
Mountain Limestone lying at a high angle, but it was evident — 
that the superincumbent beds were not Inferior Oolite. The 
accompanying diagram will serve to explain the relative position 
of these beds, as seen in three successive quarries at Hapsford, 
but it must be noticed that horizontally the section has been 
very much compressed, in order to give a connected view of the 
succession of strata there presented. Only the broad features, — 
however, are attempted to be shown, for the lower beds are much 
hidden by debris, and a ladder was not available to admit of 
examining the upper strata. 
In the larger and last abandoned quarry at A, and in the 
southern corner, the upturned edges of the Mountain Limestone — 
are immediately overlaid by the Inferior Oolite ; but as the eye —

passes along the face of the quarry to the northward, attention is — 
at once directed to a bed which comes in almost imperceptibly, 
between the Limestone beneath and the Oolite overhead, being 
approximately conformable to the latter. At the nerthern end 
it does not exceed 1 foot 6 inches in thickness, and in colour it~ 
does not differ much from the Mountain Limestone on which it
