tains, we are credibly informed of its occurrence in the southern 
parts of the province, which we did not visit, and have therefore 
left colorless on the geological map accompanying this paper. On 
the authority of Messrs. Smith and Brown, we also add, as anoth- 
er locality of this rock, Cobequid mountain in Cumberland county, 
where, it is apparent, it must hold nearly the same relation to the 
sandstone, as it does to the slate in Annapolis county. But we 
must beg leave to differ very widely from these gentlemen in 
regard to the character of the rock, which, in different parts of 
the country, occurs with the clay-slate, and to which we find 
they have applied the term primitive trap.* We think that we 
shall be able to show that this rock cannot be considered as trap 
in any form, and thatits mineral characters clearly identify it with 
the quariz rock of McCulloch. Future investigations must 
determine whether the ore bed of the South mountains is any 
where cut off by the granite, or whether it continues uninterrupt- 
edly in the more elevated parts of the range which pass to the 
southward of the patch shown on the map, as we are in fact 
authorized to conclude from the direction of the ore bed at Clem- 
ent’s. 
In the vicinity of Paradise river, a few miles from Bridgetown, 
gigantic crystals of smoky quartz (Cairngorm or Scottish topaz) 
are found among the granite boulders imbedded in the alluvium 
which forms the banks of the Annapolis river. One of these, 
found on the estate of Mr. Longley, weighed, we were told, more 
than one hundred pounds, and was remarkable for its symmetry of 
external figure, as well as the beauty and varied tints of its inter- 
nal substance. The mass, we are sorry to say, was soon broken
