18 SONEYMAN OX GEOLOGY OF XEW BRUNSWICK. 



such a rich field, so little time, hunger an impatient companion, 

 and a long day's journey. However, by diligence, perseverance, 

 abstinence and good fortune, I succeeded in making a valuable 

 and interesting collection. 



I at once recognized the Niagara limestone — the C. of 

 Arisaig — and with so good an exposure I expected to find the other 

 members of the Arisaig series. Considering this as of even greater 

 importance than the collection of fossils, I proceeded with the 

 examination of the rocks. Where I expected to find Clinton strata 

 I found Trap. In this I saw a beautiful shaped Amygdal, which 

 turned out to be a fossil. Favosites sp? This led to a further 

 search for fossils, and another was found; a beautiful section 

 in a small portion of the original stratum, the slate and Trap being 

 so closely connected that a line of connection could not be distin- 

 guished. All along the shore beyond was Trap, with intercalary 

 beds of Xiao-ara limestone. 



These exposures seem to be cross sections of the rocks of the 

 mountain which we crossed the preceding evening, and which I 

 crossed on my return overland to Dalhousie, and recrossed shortly 

 after on our way to Somerset Yale. These Trap rocks and coral 

 reefs give boldness and variety to the scenery of Dalhousie, and 

 fertility to the fields and meadows. The phenomenon of Fossils in 

 the Trap shews : — 



1. — That the Trap of Cape Bon-ami and Niagara Limestone are not 



contemporaneous. 

 2. — That the formation of the Trap was posterior to that of the 



Niagara Limestone. 

 3. — That the Trap was in molten state Avhen the fossils detached 



from the sedimentary strata dropped into it. 

 4. — That organic structure may be preserved in molten Trap, 



especially when in a condition adapted for the formation of 



Amygdaloid.
