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 Heve, 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,
