REPORT OF THE DIRECTOR I9II I25 



Stromatoporas, Heliolites and Favosites still abound ; Cladopora 

 and Trachypora are common, Camarotoechia like C. w h i t e i and 

 C. indianensis ; Whitfieldella, Rafinesquina, Orthis, A t r y p a 

 reticularis (Niagara type), Calymmene, Orthoceras, Trocho- 

 ceras etc. are present. About in the middle of this section occurs the 

 infiltrated " vein " of red sandstone mentioned above, the surface of 

 which can be traced in the fields overhead for two hundred feet away 

 from the cliff. 



From Howatson's the shore exposure continues without break 

 into the Service and LeBlanc properties, the scraggy limestones 

 maintaining their character as far as the little dock at Service's. 

 Eastward from here follows a great thickness of gray sandstone, 

 heavy bedded at first, thence passing upward into sandy shales. 

 The sedimentation continues sandy to near the end of the section 

 which terminates in the volcanic mass forming Black cape, but 

 toward the top the sands become interlaminated with thin beds of 

 volcanic ash, with red and purplish shale and eventually calcareous 

 and variegated beds succeed, becoming in places compact limebanks 

 entirely constituted of the debris of fossils. These abut against 

 the volcanics of Black cape. 



These sandstones and sandy shales are remarkably profuse in 

 corals, some of the species, as of Halysites, palpably unlike those 

 in the lower beds, but Halysites, Favosites, Heliolites, Syringopora 

 and the stromatoporas of extraordinary variety and size occur 

 together buried in this tremendous mass of sand. Plant remains, 

 apparently fucoidal, are also present in the upper sands. The 

 uppermost limestone banks are constituted of the debris of bryozoans 

 and small corals which have been weathered out over extensive 

 surfaces into exposures of much beauty and effectiveness ; but other 

 fossils than these are notably absent. The section on the whole is 

 one well worthy of attention for its paleontology as well as its 

 stratigraphy. The paleontologist would find at his hand unlimited 

 quantity and variety of corals and stromatoporas, the museum col- 

 lector fine demonstrative slabs and blocks and the stratigrapher a 

 section of the Siluric apparently unexampled for its thickness and 

 unusual composition. Leaving out of account repetitions of strata 

 which thus far have not revealed themselves in structure or paleon- 

 tology the entire section must approach a thickness of seven thou- 

 sand feet. As far as the observed and collected fossils indicate the 

 species are indirectly comparable to the later Niagaran of the interior 

 basin, with an absence of the Clinton elements. The direct com-
