shales ; thin sandstone ; laminated sandstone ; layers of sandstone ; 

 and irregular very thin black shale. 



42. The section here becomes somewhat indistinct, but shows 

 about 40 feet of gritty white sandstone, with brownish stains at 

 the lower portion, and intermixed with an irregular seam of 

 conglomerate. Dip 27°. 



43. Keddish sandstone, with an alkaline efflorescence. 



44. 40 feet : splintery shales. 



45. 3 feet : greyish sandstone, with specks of oxide of iron. 



46. Black splintery shale, thin. 



47. 5 feet : sandstone. 



48. The section is continued on the south side of the ravine, 

 the north side being obscure. Here 8 feet of shales and sand- 

 stones, alternating in beds of from 1 to 2 inches in thickness, were 

 exposed. The topmost layer is black and soft, like shaly coal, 

 about 41 feet. Dip 28°. 



49. 7 feet : brown sandstone, irregular. 



50. Slaty shale, 4 feet. 



51. 7 feet : hard black sandstone shales, with indistinct vege- 

 table impressions. 



52. 20 feet : shaly seams, alternating with thin layers of sand- 

 stone, one 16 inches thick. 



53. 6 feet : white sandstone, with (near the top) slight layer of 

 black matter, looking like coal, and shaly matter, mixed as in 

 bed 52. 



54. 30 feet : irregular seams of brownish sandstone and shales, 

 and 1 inch of soft shaly coal. 



55. 6 feet : brownish sandstone, dip about 39°. 



56. Shales, <fec., 35 feet. 



57. White gritty sandstone, dip 37°. 



Here another trap dyke (B) cuts across at an angle of 8° ; the 

 stream tumbles over it in a waterfall. Com-se of this dyke is 

 S.W. and N.E. ; average breadth 6 feet. The rock contiguous to 

 it (on the fm'ther side) is 57 bed, but ihe dyke also cuts across 

 58, 59, and a portion of 60 bed. 



58. Black shale, with irregular seams of sandstone. 



59. Six feet : white sandstone. At 59 the section is again con- 

 tinued on the north side of the ravine, where it is more distinct 

 than on the south side. 



60. 3 feet : black splintery scaly shales. 



61. 3 feet : white sandstone. 



62. 10 feet : irregularly bedded shales and sandstone mixed — 

 faint fucoid-like impressions. 



63. 25 feet : white sandstone ; 31° dip. 



64. An irregular series of thin beds, as follows : — 



4 feet : splintery shale ; 4 feet : white sandstone ; 8 feet : irre- 

 gular shales and sandstone ; 4 feet : white sandstone ; black shale ; 

 4 feet : white sandstone ; and 6 feet : irregular shales„ 



65. 25 feet : white sandstone. 



66. 10 feet : black splintery shale.
