NOVA SGOTIA GEOLOGY — HONEYMAN. 327 



We afterward proceeded to " Riversdale station," of the Pictou 

 railway, i. e., in a northerly direction, toward " Mount Thorn." 

 Archaean boulders were seen in abundance occurring along the 

 road, except where the mud and mire were too deep for any 

 stone to raise its head They were seen at the station, and on the 

 north of Salmon River, in sufficient abundance and magnitude, 

 and at no great distance from the mountain. We were now 47 

 miles N. of Clam Bay, and 3 miles S. of Mount Thorn, From 

 Riversdale we returned by railway to Halifax. 

 Part V. — Pictou County. 



I returned to Riversdale station and thence proceeded onward. 

 On both sides of the line of railway, Archaean boulders were 

 observed. I stopped at West River station for the purpose of 

 examination. Here boulders abound. Those in front of the 

 station are occasionally of large size, most of them are syenite,, 

 one is granite, being composed of quartz, muscovite and orthoclase 

 and resembling the granites of Halifax. It is much different 

 from the other granites which I have found in the Cobequids, 

 although it is unquestionably derived from rocks of the same 

 series. I then walked along the road which leads to settlement 

 S. E. of the station. The usual boulders were observed all the 

 way, — 1| miles. I collected at the end of the road, syenites, 

 diorites and dioritic amygdaloid. Further examination in this 

 direction is deferred to another season. Returning to Halifax I 

 stopped at Milford station for the purpose of examining the roche 

 moutonnee, referred to in Part III. Starting from Milford in 

 search of this rock, I had some difficulty in finding it, so that I 

 travelled about thirty miles before I succeeded in my search. 

 These wanderings, however, were of service, as they showed me 

 Archaean boulders in all directions, and the want of triassic 

 boulders where I expected to find them. On the roche in question 

 I observed five well-defined parallel lines having a course S. to E. 

 N. 10 W. Besides these are parallel ruts, having a course S. 

 40 E., N. 40 W. Two of these were bent and turned in a direc- 

 tion S. 30 E. The character of this rock, quartzite, its position 

 13 miles east of the Halifax meridian, north side of the band of
