344 Notice of a Scientific Expedition. 



On leaving Grindstone Island, our homeward course still lay along 

 the shores of New Brunswick. These shores are steep, but slope to 

 the bay, they are not a bare perpendicular ledge of rocks like the op- 

 site coast of Nova Scotia. There were only two places which cir- 

 cumstances permitted us to examine, and at one of these we could 

 not land. The first I shall mention, and which we examined with 

 some care, is near St. Martin's Head. The minerals we observed 

 were asbestus, serpentine and indifferent specimens of schorl. The 

 predominant rock is talcose slate, against which, we found the re- 

 mains of a stratum of the old red sandstone reposing ; remains which 

 have as yet resisted the warring elements. A conical shaped mass 

 about forty feet high, and twenty or thirty feet across it, where it 

 plunges into the sea, is one of the largest of the remains of this stra- 

 tum yet remaining insitu. 



The shore is strewed with boulders of primitive rocks and a con- 

 glomerate, which may have belonged to the new red sandstone. 

 Some of these were evidently members of the graywacke formation. 

 The texture of this sandstone is coarse and harsh, is made up of an- 

 gular particles which adhere firmly ; it is tough and not easily broken. 

 We proceeded twenty miles farther and came to anchor near Quaco. 

 This place appeared still to be underlaid by talcose slate. A thin 

 stratum of sandstone may still be seen resting unconformably on it. 

 The light house which is built on a tongue of land running several 

 rods into the bay, is founded immediately on the ruins of thig ropk 

 yet in place, and still exhibiting its stratification ; the diameter of these 

 ruins is not much greater than the base of the lighthouse and about 

 ten feet thick. The stratum dips to the east at an angle of 20° or 

 25°. These few remarks on the geological structure of the coast of 

 New Brunswick are not made with a view to settle the interesting 

 points on which they bear, but to call the attention of future observers 

 to them. It would be interesting to know what and how great have 

 been the changes on the coasts of New^ Brunswick and Nova Scotia 

 in comparatively modern times. 



From Quaco we proceeded directly across the bay to Digby. It 

 is situated on the Annapolis basin, its location is pleasant and the peo- 

 ple are kind and hospitable, as we found all Nova. Scotians to be : but 

 it is inconsiderable in point of size and population. Here we renewed 

 our acquaintance with the trap formation, but as nothing new or pecu- 

 liar came under our notice, we shall drop for the present our geologi- 

 cal remarks, and take up the mineralogical part of our journal. In
