NOVA SCOTIAN GEOLOGY. — HONEYMAN. 201 



Diorite. Division No. 3 runs N. 82 E., a distance of 2.2 miles to 

 John McDonald's Hill, Blanchard, passing through Middle Silu- 

 rian strata A. At McDonald's hill it cuts an interesting outcrop 

 of D strata (Upper Silurian,} with characteristic fossils. Division 

 No. 4 passes N. 59 E., a distance of 0.6 of a mile, at its termina- 

 tion it cuts the Blanchard Iron Ore. This is a bed of fossilifer- 

 ous red hematite 30 feet thick. The ore and the containing 

 s trata have fossils characteristic of A (Middle Silurian). I will 

 call this Iron Ore, No. 2. Division No. 5 runs S. 45 E., a dis- 

 tance of 3 miles. The half of this distance, 2.5 miles, it passes 

 through Middle Silurian strata and then it reaches crystalline 

 metamorphic rocks of Archaean age (Lower Arisaig). It traver- 

 ses these a distance of 2.5 miles to McPhee's, still on the north 

 side of East River Division. It continues in the same direction 

 S. 45 E., a distance of 0.6 of a mile, crossing the river and pass- 

 ing into a band of black metamorphic Middle Silurian strata 

 These have an east and west strike. At a farther distance of 6.8 

 miles, west, we reach the first outcrop of Iron ore at McDonald's 

 due south of Blanchard. I shall name this Iron Ore No. 3. 

 Remarks on the Division of Section Line No. 2. 

 Division 1. 



The series of Silurian rocks of this division might be regarded 

 •as a typical series, if Arisaig did not put in a prior and superior 

 claim. I shall consider the series of Springville in the order of 

 its development. D strata at McLean's have received the most 

 attention on account of the abundance of fossils. The fossils and 

 their order of occurrence correspond in a striking manner with the 

 typical D at Moydart, Arisaig Township. 



The fossils are, with a few exceptions, of the same order, genera 

 and species ; the mode of their occurrence and association remark- 

 ably corresponds. A ledge on the height at the back of McLean's 

 and to the north of David's lake, has precisely the same fauna as 

 a corresponding ledge at Moydart. The fauna are Comulites flex- 

 uosus, Homalonotus daw&oni, Spirifer swbsulcatus and Avicula' 

 honeymani, associated and in abundance. The only differ- 

 ence is in the degree of metamorphism and in the state of preser- 

 vation. All the strata of the series of Springville are more highly
