From this point northward the section is concealed by an old sea beach 

 or talus for a distance of 400 feet to the projection of the eruptive mass 

 called the Bon Ami rocks. The total thickness of the sedimentary series in 

 Stewart's cove is thus approximately 430 feet in a sea cliff section 1700 

 feet long. The fossils of the fauna have been chiefly obtained from beds 1,7, 

 8, 9, 10, n, 12, 13 and 16. In their distribution there is some uniformity 

 but strong contrasts are also evident in the range of leading species. These 

 facts will be evident upon study of the accompanying table.
