SECTIONS 



As a continuous exposure of the rocks could not be had 

 in any one line, three secftions were made. The measurements 

 were made with tape, hand level, and by plotting on the map. 



Section A 



Secftion A begins with the top layers of the Calciferous and 

 runs for about a thousand feet along the east shore of Bulwagga 

 Bay. The strike here is N. 30° E. 



In ascending order the measures were: 



A I. Ivight gray, pure, dolometic limestone in 

 two heavy beds whose surfaces were uneven and 

 worn into humps and depressions. Probabl}' 

 Calciferous, 3 ft. 3 in. 



2. Thick beds of slaty shale, with occasional 

 bands of hard, fine-grained, sparkling limestone. 

 The latter layers contain numerous fragments of 

 Lingula brainerdi sp. nov. Their surfaces are 

 covered with an undetermined species of fucoid. 



Pyrite is very abundant. 12 ft. 7 in. 12 ft. 7 in. 



3. Heavy bedded, impure gray limestone, 

 weathering to a rough, sand}^ appearance. No 



fossils. 5 ft. o in. 17 ft. 7 in.
