It is in these lower beds the collector must search,leaving the ferruginous sands as entirely large geological hammer and a couple of strongchisels are indispensable ; even with these tools itwill be found hard work extracting fossils. The bestplace for descending the cliff is a path a few pacesbeyond the flag-staff which indicates the coast-guardstation; this is indeed almost the only safe placewhere a descent can be made. Supposing the tide tobe receding, it will be advisable to walk a shortdistance round Atherfield Point to the westward;here we at once see several feet at the base of thecliff of a brown colour, numerous lumps of the samebeing strewn along the beach ; from these lumpswell-preserved fossils may be obtained, the sectioncorresponding to Nos. 1 and 2 of the above Fig. 46.—Grevillia anceps.

It is afterhigh tides and heavy seas that the cliffs are mostexposed, and it is better to fix a day so that the tideshall be on the ebb during the five or six hours it isis intended to study the rocks. The whole of theAtherfield Greensand is divided into three maindivisions, in the lowest of which the fossils chieflyoccur. The substrata of the lower section care thusgiven by Mantell— (1.) Lowest Greensand clay, brown, 3 feet thick.(2.) Perna Mulleii beds, 2 feet.(3.) Atherfield clay strata, 100 feet, abound infossils in lower portion, few in middle, a smallspecies of lobster in upper part. This clayis blue.(4.)
