NOVA SCOTIA GEOLOGY — HONEYMAN. 327 
We afterward proceeded to “ Riversdale station,’ of the Pictou 
railway, i.e., in a northerly direction, toward “Mount Thom.” 
Archzean 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 Thom. From 
Riversdale we returned by railway to Halifax. 
Part V.—Picrou County. 
I returned to Riversdale station and thence proceeded onward. 
On both sides of the line of railway, Archean 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,—14 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 
Archzan 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 K., N. 40 W. Two of these were bent and turned in a direc- 
tion 8. 30 E. The character of this rock, quartzite, its position 
13 miles east of the Halifax meridian, north side of the band of
