HONEYMAJ^ ON NOVA SCOTIAN GEOLOGY. 38T 



far as the Great Village, exhibiting the same characters as on the 

 Intercolonial Railway. Beyond the Great Village all is obscure. 



We would ap^ain traverse the Cobequid Mountains from the- 

 north, beginning at the county line, te© miles west of the Inter- 

 colonial Railway, and on the road to Five Islands. We are on the 

 north side of the central band. The underlying rock, as shown by 

 the outcrop, is granite. This granite is coarse and porphyritic, 

 the mica is black, the felspar is reddish white ; it is different from-^ 

 any other granite that I have met with in Nova Scotia — in position.- 

 I have found it frequently in boulders, and specimens have been 

 brought to the Museum from Cape North, in the Island of Cape- 

 Breton. This granite is succeeded on the north by lower carboni-- 

 ferous conglomerate, in the same manner-jas are the syenites of 

 West Chester and Greenville ; the Silurian^ of Wentworth, being 

 still absent or overlapped. It is thus probable that forty square ■ 

 miles, at least, of crystalline and uncrystalline rocks have beens 

 denuded and obscured on this side of the Cobequid Mountains by 

 the lower carboniferous seas . This lower carboniferous conglomerate 

 is the southern base of the Cumberland Coal Field. Crossing the 

 Mountains towards Five Islands for a long distance no outcrops 

 are seen : the surface boulders and soil seem to indicate three or 

 four miles of underlying granite, similar to that of the outcrop 

 already noticed. Farther on we have frequent outcrops of granitoid^ 

 rocks — syenites and diorites. About two miles from Five Islands 

 the outcrops are of bedded crystalline rocks — gneisses and quartzites. 

 The extension of these to the east, on North River, shows syenitic 

 gneiss with crystalline limestone (marble). This marble is well 

 known, it has been quarried to some extent with the expectation of 

 obtaining masses fitted for sculpture, but without success. 



The position of this marble and its associations are sufficient to 

 indicate its relationship to the marbles and serpentines of Arisaig, 

 N. S., and George's Mountain, C.B. — Yide Transactions^ 1872-3. 

 Paper by the author. , The syenitic gneiss, in the vicinity of Bass 

 River, seems to belong to the same band of rocks. This seems to 

 overlie the strata which contain the harite veins of Five Islands. 

 It will require still farther investigation to determine these points^
