 COBEQUID MOUNTAINS, &c. 



About three miles west from the Wentworth Station, of the 

 Intercolonial Railway, (vide, preceding pajjer by the author) we 

 find ourselves on the north side of the Cobequid Mountains, and 

 on the road from Greenville to the Londonderry Iron Mines. Here 

 we find the lower carboniferous conglomerate and the red syenite. 

 Any intervention of the bands of rocks which occur on the Inter- 

 colonial Railway, between Smith's Brook and the carboniferous of 

 Caldwell's Brook, as I previously noticed there, have been denuded 

 and overlaped. 



Near Purdy's Inn, West Chester, on the road from Amherst to 

 the Londonderry Mines, we find the lower carboniferous conglo- 

 merate and the red syenite occurring in a similar manner. This 

 position is six miles distant from the proceeding. The outcrops 

 along both roads, southward to their meeting point, are of granitoid 

 rocks : syenites and diorites. Between this point and the county 

 line there are outcrops of granites. The granites are evidently 

 massive, they are fine grained and of dark colour. South of the 

 county line we have outcrops of the next band ; these exposures 

 exhibit much greater variety than was seen on the Intercolonial 

 Railway. In one exposure the strata are beautifully banded. The 

 dark green homogeneous diorites having interbedded red and green 

 gneissoid strata ; other exposures show massive homogeneous 

 diorites ; others show gneissio and quartzite strata, and the last 

 exposures, a little below the bridge on the east side of the road, shows 

 dark green diorite, which may readily be mistaken for uncrystalline 

 rock, the hammer however shows that it is characteristically hard 

 and crystalline. These are succeeded by uncrystalline rocks, as on 

 the Intercolonial Railway. By exposures we find that the band in 

 this direction is about half a mile wide. About the middle of it 

 there is a great deposit of ankerite. At the time of my last visit, 

 in 1866, this was not worked. It is now used as a flux instead of
