Since, however, the days when I scrambled over the rough under- 
cliff and up the craggy face of Cap La Heve, the important attention 
which has been given to the quaternary deposits and the geological 
traces of the human race, has rendered one spot which excited then 
my interest still more interesting. It is a deposit of siliceous sand> 
containing recent species of shells, underlying a capping of ordinary 
angular flint drift-gravel. 
Between Frascati's well-known hotel and baths, near the pier at 
Havre, and the commencement of the chalk cliffs of Cap La Hcve, the 
ground gradually rises into a low cliff" of some twenty-five or thirty 
feet high, capped by a thick deposit of red clay, sand, and angular 
flints, exactly in appearance resembling the ordinary flint-drift that 
covers the chalk-hills of England. This flint-drift is seen on the coast 
in considerable thickness, covering the irregular surface of the chalk, 
and filling up numbers of those extraordinary cavities so familiar 
under the name of sand-pipes. It appears to have come down or over 
the pretty valley of St. Addresse, covering the subjacent rocks of 
every description to the present sea-level. Near the limekiln by 
Perrey's mill, the low cliff" referred to commences, and consists of 
about 10 feet of red, flint-gravel drift; gradually becoming higher, 
until near the sea-baths it has acquired an elevation of 30 or 40 feet. 
It is here that at the base of the cliff" we perceive the sand to contain 
several bands of the semi-fossilized shells of species still living in the 
district, and in great abundance in the sands of the opposite coast 
at Honfleur, Trouville, and Dives. As the cliff" increases in height.
