Section No. II. 



West side of Mullen's Cove, and between Mullen's Cove and 

 Collingham Bight. 



a. Coarse felspathic gneiss, with small garnets distributed 



through the mass 



b. Crystalline Limestone 35 



c. Coarse grey garnetif toils gneiss with large garnets dis- 



tributed through the mass 



d. Ferruginous gneiss containing Iron pyrites in thin bands. 



Both Series arc regular, and garnets appear pretty generally 

 distributed. In some of the beds crystals and grains of magne- 

 tite are visible. The Crystalline Limestone is white and sac- 

 c.haroidal in parts. It is seamed near its junction with the 

 overlying gneiss, with thin lenticular bands of micaceous schist, 

 and a thin band of felspathic gneiss. It contains near the 

 gneiss crystals of magnetite and specks of carbonate of copper. 

 Its colour is white to a pale yellowish tinge. Some bands are 

 very pure and resemble coarse loaf sugar. When treated with 

 hydrochloric acid the residue contiins milk-white opaque grains 

 an 1 grains of light semi-transparent grass-green mineral, which 

 in some parts appears to be disseminated through the miss. 



Near the narrows of Kebmki Bay, 75 miles north-west of 

 Mullen's Cove, two kinds of Crystalline limestone are found in 

 the shingle, one white and compact, the other grey and coarse 

 in structure, but the rock was not seen in place. 



The structure of the strati as seen on the coast leads to the 

 impression that the limestones are brought to the surface by 

 undulations. The Moravian Missionary at Hbpedale, showed 

 me a slate of crystalline limestones which he had picked up near 

 to that station.
