218 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Jan. 12, 
Drifts of the “ Upper and Lower Series.”’—Between Shrewsbury 
and Bridgnorth these consist for the most part of (1) Upper gravel 
and sand, (2) Unstratified sandy clay “with muddy gravel,” 
(3) Lower gravel and sand. According to the observations of 
Mr. Maw, the greatest vertical development of them occurs at Stret- 
hill, near Ironbridge, where the beds (no. 2) attain a thickness of 
70 feet. At Frankwell, Shrewsbury, a locality where marine shells 
are found in considerable abundance, the following section of the 
beds is displayed in a sand-pit near the Ferry, on the south side of 
the Severn.

The above Section must be considered only approximately cor- 
rect as regards the thickness of the beds, on account of the loose, 
uncompact nature of the sands and gravel, which, falling down from 
above, form a talus obscuring the face of the section. Between 
the beds nos. 4 and 5 I observed two large angular blocks, about 
one foot apart, lying on the surface of the sand; and I was told by 
one of the workmen that a large rounded boulder of grey granite, 
which I found lying at the bottom of the pit, had fallen from the 
same level. At the north-west end of the pit, near the surface of 
the ground, was seen a compact mass, exhibiting alternate layers of 
dark red sandy clay and dark red sand, in which signs of contortion 
were marked. I observed a few small pebbles sticking in it, but no 
boulders. In the heaps of gravel at the bottom of the pit were 
numerous scratched pebbles, and small boulders, many of which 
were flat on one surface. ‘The marine shells, some of which were 
entire, but most of them fragmentary, appeared to occur chiefly in the 
light-grey-coloured shingly gravel. On the occasion of a third visit 
to the spot, a clearing away of a large talus of débris towards the 
west side of the pit exposed a thick deposit (no. 5) of bright-red 
sand, containing but few seams of shingly gravel. 
As examples of the general character of the deposits in the 
neighbourhood of Worcester, I have selected those found in the 
gravel-pits of Kempsey and Hawford Bridge.
