114 HONEYMAS NOVA SCOTIAN GEOLOGY. 



picture the phenomena. An interesting geological problem thus 

 presented itself for solution, and no time was lost in beginning the 

 process. 



In the clay bluff many interesting specimens were collected of 

 representative boulders, e. g. syenites, gneisses, diorites and amyg- 

 daloids. A fine specimen of agate jasper was found embedded 

 in the clay, whose triassic-trappean origin was readily recognized. 

 Specimens in the Provincial Museum, collected at Blomidon by 

 the late Dr. Webster, are strikingly similar. On the beach east of 

 the bluff boulders abound — gneisses, granites, diorites, amygda- 

 loids, porcellaneous jaspers, the collection on trying to make a 

 selection is sufficiently puzzled and perplexed. 



On this beach Mr. Stirling found an agate jasper of considerable 

 size ; on the same beach Mr. A. James, barrister-at-law, found a 

 large and very beautiful specimen of one of these jaspers, the 

 previous summer. I w r ould here particularly notice the fact, that 

 the granites and gneisses referred to as occurring among the 

 boulders to the east of the harbour are peculiar. They are different 

 from the known granites and gneisses of the band No. 1 of our 

 section. The granites are the same as I found at Maccan Mountain 

 in the Cobequid Mountains, associated with the syenites. The 

 gneisses are of the Laurentian (?) of the Cobequids — Vide Five 

 Islands and Acadia Mines sections, in my paper of last Session , 

 Transactions 1873 — 4. 



There are also many porphyries and jaspers, which I cannot 

 refer to their original rocks. It is possible, however, that even 

 these may have their home in the Cobequid Mountains. 



On the same beach and at the same time, I found a boulder of 

 yellowish grit, perforated in a singularly regular manner. After a 

 little puzzling I recognized it as the bed of stigmaria, the perfora- 

 tions having been the beds of the rootlets. Here was a carbonifer- 

 ous boulder which had travelled from the carboniferous band to 

 the north, a distance of at least 35 miles. 



Not far from this was found another perforated boulder. This 

 was of olive green quartzite, the perforations were casts of 

 crinoidal columns. This doubtless belonged to the silurian forma-
