ROCKS OF NORMANDY. 257 
taken from these pits, but think that the quarries have been disused, 
and may be situated at or near the village of Montmartin-en- 
Graignes, whilst those I visited are more than two miles to the 
westward of it, near the hamlet of Le Cap. 
Of the four pits noticed in the last-named locality, one gives the 
following section (fig. 6) :—

G G. Brown loam with irregular pebbles of quartzite and grit dispersed 
throughout. 
a a. Greenish sand-bed. 
b 6. Tough, coarse-grained, whitish sandstone, with occasional pebbles often of 
clayey material. 
The beds are displaced by a fault with a downthrow of about 
6 feet, also affecting the diluvium. 
Another pit shows :— 
2 feet of red and grey clay, with sandy concretions, on light greenish sandstones 
of unequal durability, the harder portions exhibiting more even bedding ; 
exposed to a depth of 8 feet. 
Of the two remaining pits, one exhibits the following section, 
about 20 feet in depth :— 
1. Soil with pebbles. 
2. Ochre and grey-coloured sand with concretions of a conglomeratic character. 
3. Light greenish-grey, coarse, tough sandstones, containing a marly seam near 
the base of the section. 
Not far to the westward of the above pits, a well in course of 
construction in a farmyard, at the hamlet of Le Cap, showed red 
marls by its sides as far as visible, and the stuff thrown out and 
piled round its mouth was of the same character. The surface soil 
was sandy. The workmen informed me that 60 feet had been sunk 
through the marls without bottoming them. In a field adjoining, 
about 3 feet of loose surface sand of a greyish colour was observed, 
probably the redistributed relics of sand-beds on the marls, and 
formerly continuous with those exposed in the pits; so that the 
latter appear to rest directly on marls or to pass into them through 
dovetailing or intercalation.
