5Q 



Company, is located in the northwestern part of Port 

 Colborne to the west of the interurban track (Port Col- 

 borne division of the Niagara, St. Catharines and Toronto 

 Railway) at the crossing of the Grand Trunk switch. Very 

 little quarrying has been done, but quite a large surface 

 has been stripped and this furnishes an ample opportunity 

 for collecting. In general the rock is too hard for successful 

 collecting from the unweathered portions. Corals and 

 stromatoporoids are especially abundant and may be 

 seen studding the exposed surface, while several species of 

 gastropods and a half dozen brachiopods are not uncommon.

5. Hard bluish limestone with rough black 

 chert. Where weathered the chert 

 stands out in relief. These beds are 

 quite fossiliferous and afford good 

 collecting. The top surface is well 

 glaciated at the west end of the quarry. 1-5 • 458 



4. Dark bluish limestone containing an 

 abundance of silicified compound 

 corals which afford good collecting in 

 the central portion of the quarry 1-5 -458 



3. Blue limestone with very little chert. 

 The lower half is filled with corals 

 chiefly of the small branching type. 

 Among these Cladopora labiosa (Bil- 

 lings) is abundant. In the cracks and 

 crevices of the eastern portion of the 

 quarry some small but very good spec- 

 imens may be found 3 -915 



2. Blue limestone with some black chert and 

 often with shaly bedding planes. 

 Sometimes the bedding planes are very 

 rough and uneven, chiefly because of 

 the presence of large corals. Crinoid 

 stems of large size are conspicuous 

 but the heads are rare. These beds 

 are shown chiefly in the water hole. . . 5-83 1-78
