NOVA SCOTIAN GEOLOGY — HONEYMAN. 137 



2. — Specimens of Gypsum were subsequently received from 

 Mr. John Boak, of Halifax. These are of character and quality 

 identical with the Nova Scotia Lower Carboniferous Gypsums. 



3. — Lately other specimens were received from Mr. John 

 Tucker, of San Francisco. There are, first, a specimen of coarse 

 agate, with cavities containing quartz crystals. Second, three 

 beautiful jasper specimens, blood red, green and yellow. 



These are all from Grindstone island ; and are evidently trap 

 minerals. 



From these observations we are led to infer that the Magdalen 

 islands are of some geological importance and its minerals of 

 possible economic value. 



Their geology appears to indicate the existence of an enormous 

 submerged area of Carboniferous strata lying between Gaspe, 

 Canada, and Port au Port, of Newfoundland, extending to Cape 

 Breton, Nova Scotia and New Brunswick. 



On a part of this Prince Edward Island's Triassic Sandstones 

 seem to rest. 



Mr. Fox, the collector of customs, who has been a resident of 

 the island for twenty years, informs us that the elevation of 

 Amherst island, Grindstone island and Entry island is from five 

 hundred and six hundred feet; that trap is prevalent, on these 

 islands, that one of the specimens is undoubtedly derived from 

 this. 



The first looks like a specimen found in situ ; the others may 

 be transported boulders. 



The Jasper pebbles are identical with some that I received 

 about six years ago, with beautiful agate pebbles, from Gaspe 

 bay, which lies to the N. E. of Grindstone island. 



The' Gaspe pebbles are thus referred to in Logan's Geology of 

 Canada, 1863, page 404 : 



" Associated with these are others (pebbles) as of agate and of red 

 yellow and green Jaspers, often brilliant in colour, which have 

 probably been derived from the Conglomerates of the Gaspe 

 Sand stones. These Jaspers and agates are known among 

 collectors as 'Gaspe pebbles.'" Of course the conglomerates in this 

 ■case can only be regarded as the secondary source of the ' Gaspe
