running stream. The gravel is a mass of pebbles and flat 
slabs, mixed with sand, and near the bottom was found a 
large Silurian angular Boulder, probably Caradoc from the 
Malverns, 2 feet long, 1 ft. 6 in. wide, and 3 inches thick. 
This is now in the Museum at Gloucester. 
In addition to the long list of Silurian and other fossils, 
hard chalk, pieces of Syenite, Licky Quartz, Granite, and 
Carboniferous Limestone, which I gave in my paper, (vol. V. 
page 81,) I found Gryphza incurva and Cardinia both from 
Lower Lias. 
And now to the further evidence of ice action in the plain: 
commencing at Sharpness Point, where on the removal of the 
gravel for the works of the Midland Railway, the surface 
of the hard beds of the Old Red Sandstone was found to be 
eroded and furrowed, with no trace of mud left. At and around 
Gloucester, extending beyond Tewkesbury, I have seen many 
like examples of erosion in the Lower Lias Mar!s. 
To shew this is not a mere local example I would mention 
that Mr. C. Moore in the Quarterly Journal of the Geological 
Society, December, 1867, says :—‘‘ In the neighbourhood of Bath 
wherever the Drifts are passed through they are found to lie 
on the Upper Blue Marls of the Lower Lias, which present 
long lines of furrows channelled out either by Glacial action 
or the effects of Post Pliocene erosion.” Indeed, the same 
phenomenon holds good throughout the greater part of the 
low ground of this country, where gravel occurs: on the Chalk, 
in various parts of Norfolk, Suffolk, Kent, around Freshwater 
in the Isle of Wight, and on the great Western Railway between 
Didcot and Reading, as well as in the New Red, at Beeston in 
Nottinghamshire. I have noticed it also on the brecciated 
Oolite close to the Peterborough Railway Station. 
For some years I have been occupied, as my limited leisure 
would admit, in attempting to correlate the Gravels of our 
district with those of the East Coast and other parts of England, 
and I may here remark that I believe in these planed-off surfaces 
T have found a starting point common to all areas, and which 
I may probably make the basement line of a future paper.
