110 HOXEYMAX — NOVA BCOTIAN GEOLOGY. 



The line then crosses the Cobequid Bay a distance of 4 miles. 

 It is presumed that the formation underlying the Bay is new red 

 sandstone, of Permian (?) and triassic age. 



On the north side of the Bajr the line passes through this forma- 

 tion to the length of 3J miles. The formation extends to the east 

 of the line about 20 miles, and to the west about 130. The rocks 

 are coarse red conglomerates and red sandstones. Associated with 

 these is a great dyke and outliers of homogeneous and amygdaloidal 

 dolerite (Trap.) This is the great depository of Nova Scotian 

 Trap minerals, e. g. Zeolites, chalcedony, agates, jaspers, 

 amethysts. 



About 10 miles W. of the line Bass River, these traps have their 

 beginning. 



Bass River. — This is a point of interest in connection with my 

 investigations, as I will show in a subsequent part of this paper. 

 "West of this are Five Islands, Two Islands and Partridge Island, 

 celebrated for their trap minerals. Cape D'Or, known on account 

 of its native copper. Blomidon, North Mountain, Digby Neck, 

 &c. All celebrated on account of their trap minerals. 



From Bass River to Briar Island, the two extremities, the 

 distance is about 160 miles. This is the only trap having zeolites 

 to be found in Nova Scotia. This is another interesting fact to 

 be particularly attended to. The line then traverses the carbon- 

 iferous, band on the south 6ide of the Cobequid Mountains, a 

 distance of 2f miles. This may be regarded as a part of the 

 Section of the I. C. Railway, through the Cobequid Mountains, 

 as this section now approximately coincides with our line of section. 

 This carboniferous band extends to the west of our line about 63 

 miles (to Cape D'Or) , to the east about 45 miles (to the coal fields 

 of Pictou) on the side of the Cobequid Mountains. The part of the 

 band west of our line of section, which interests us more particu- 

 larly at present, corresponds with the character of the formation 

 generally. It has sandstones, shales and clays with flora, small 

 coal-seams, limestones, and conglomerates. The conglomerates 

 are largely composed of boulders of the underlying crystalline 

 rocks, which may be readily appropriated by the formations of 6uc-
