angular fragments of rocks would render it very difficult to wash, per 
when it occurs in situations where water cou!d be aaa obtained 
for sluicing, The gold which it contains is coarse and angular, often still 
attached to the quartz, and showing but little evidence of long trans- 
portation. The “ Boulder Lot,” at Sherbrooke, has yielded a consider- 
object of attention. 
Everywhere over this whole district the eye of the observer is constantly 
arrested by the long lines - granitic and quartzitic pn which have 
been left in trains by the ancient glaciers upon the surface of the pol 
ished rocks. These at esse recall strongly the seein of the Swiss 
— and rival them in the magnitude of the travelled blocks. Some 
of ost striking cases of this sort which I saw were in the vicinity 
of Roaancdehes Harbor, also on the flanks of the Musquodobit Moun- 
— and on the elevated plateau between Jeddore Bay and Ship Harbor,

meridian, and is usually south by that quantity. But to the east and
