The direction of the strike and the year when taken, were 
obtained through Mr. Carman of the Public Works and Mines 
Office. Some of the courses of the strize were taken by myself, 
others by parties to whom I have applied in the present year. 
The bearing is magnetic. 
The unmistakable traces which are so marked shew that east 
glaciers must have once existed here, or, that these markings 
are due, as Dr. Dawson in his Acadian Geology seems to favour, to 
the abrasion of the rocks by icebergs coming from the direction 
of the sea. We have the carefully pr tere and almost conclusive 
reasons given by Dr. Dawson on the glaciers and icebergs of the 
Post Pliocene period, published in 1868; but we have other 
authority on glacier action by equally active observers, such as 
Professor Tyndall and others. In examining the evidences which 
are illustrated by markings or striation running in the same 
general direction in Nova Scotia, and other phenomena which 
they suggest, it is not easy to assume any definite conclusion 
respecting this theory or:that. Whilst quoting sueh authority 
let us approach this subject gradually. 
Professor Tyndall, after discussing snow-crystals and regelation 
in his work “ Heat as a mode of motion,” discourses from actual 
observations of his own among the Alps, as well as from the 
records of other writers on the glacial action now going on in the 
Himalayas, the Andes and many other snow-laden mountains ; 
and propounds the theory that the scars, flutings and furrowings
