I NOW purpose to record the most important observations made 

 by me since the year 1855. This is the date of the publication of 

 the first edition of Dawson's A.cadian Geology, To this classic 

 work and the friendship and suggestions of its distinguished author, 

 I am indebted for an introduction to the practical study of Nova 

 Scotian Geology. I commenced by directing attention to the 

 vJeology of Arisaig, a locality and a township in the county of 

 Antigonish. Antigonish was the place of my residence. I made 

 the rocks of Arisaig a special study for several years. I have 

 examined them with the greatest minuteness. The position and 

 appearance of its rocks are familiar as the objects in my parlour ; 

 their fauna are my intimate acquaintances. 



In my first communication ^* On the Geology of Arisaig," read 

 before the Nova Scotia Literary and Scientific Society (the short- 

 lived predecessor of this Institution), I shewed from the character 

 of a large collection of fossik made in what was then considered to 

 be the upper rocks of the Arisaig series, and what are now designated 

 the Upper Arisaig (vide Acadian Geology last edition) that the 

 rocks are not Devonian as was then supposed, but the equivalents 

 of the Upper Ludlow of England, and therefore Upper Silurian. 

 While my paper was in the press Dr. Dawson informed me by 

 letter, that he considered the rocks in question as probably the 

 equivalents of the Lower Helderberg of the United States, and 

 therefore Upper Silurian. Prof. Hall subsequently, and afterward
