which are of gigantic size, individuaLs six, eight, or even ten 

 feet in diameter being common. Many of them exhibit 

 grotesque imitative forms, and are often taken for pre- 

 hivStoric monsters, which some freak of nature has preserved 

 in all their grotescjueness. These concretions are of similar 

 size to those found in the gorge of Eighteen Mile Creek near 

 the forks, and it is possible that the same bed is represented 

 in both localities. Another small fault occurs in this clift". 



The septarium-strewn beach hnally gives way once more 

 to a sandy and ])ebbly beach, behind which the banks again 

 consist of unconsolidated material, which completeK* con- 

 ceals the underlying shale beds. 



Beyond Muddy Creek the shales appear again. The bank 

 is at first only eight feet high, but soon rises to the height of 

 thirty feet or more. This is at Harrison's P'oint, a rocky 

 headland, the base of which is washed by the waves the year 

 round. The clifit' bevond, descends jDcrpendicvdarly to the 

 water, and ordinarily passage along its base is impossible. 

 ThcvSe conditions continue for some distance, after which the 

 cliffs are again fronted by sand and gravel beaches. Several 

 of the points beyond this, however, project far out into the 

 water, so that ordinarily travel on the beach is impracti- 

 cable. Near Cattaraugus Creek the banks are low, and for 

 the most part composed of unconsolidated material. 



It will be observed that the highest members of the 

 Genesee stage, /. e. the Naples (Gardeau) flags, are not 

 exposed in the section along the lake shore. This is due to 

 the fact that the sections extend in a general south-west 

 direction, Avhich does not vary much from the direction of 

 the strike of the strata in this region. Consequently most 

 of the sections exhibit strata having a very low dip, and 

 therefore no great stratigraphic ascent has been made by 

 the time the comity line is reached. The flagstones oi this 

 stage, as well as the sandstones of the lower Chemung stage 

 (the Portage sandstones) are however, found in the higher
