blende, was not maguetic—the sides of the vein composed of 
the felspathic rock we have described, were strongly so; and 
Mr. Hamel further ascertained, that the south side of the vein 
attracted the north pole of the compass, and the north side 
the south pole. To remove the chances of error, the experi- 
ment was repeatedly tried, with success, both by applying the 
compass to the sides of the vein, and detached fragments to the 
compass. The vein was about three inches thick, and had a 
N. W. bearing. When the compass was laid on the centre of 
the vein, the local attractiun was observed in one place, to be 
equal to ninety degrees ; in some parts of the same rock it was 
still more, even to a complete reversal of the needle: Ata 
subsequent period, the place was again visited by Mr. Hamel 
in company with Mr. Nixon, and these observations confirmed. 
Upon our return home, the specimens which had been examined, 
were re-examined, and found to possess a feeble magnetism, 
but no polarity. The islet upon which the foregoing observa- 
tions were made, forms one of a cluster at the mouth of la Grande 
Décharge, to which the name of Dalhousie was given ; none 
of them appear to be more than twenty feet above the water. 
On leaving this place a northerly course was again taken until 
reaching a fine sandy shore, we landed for the purpose of mea- 
suring a base preparatory to a survey of the lake about to 
be commenced by Mr. Hamel. These sandy shores are very 
characteristic of the lake, and add very much ,in our opinion 
to its beauty, though nothing to its fertility. Where no rock 
appears, five shining yellow sand is substituted, and where they 
appear together, the former rises through the latter assuming 
that isolated appearance which has been mentioned. This sandy 
girdle is not confined to the margin of the lake, but passes a 
short distance into the interior, bestowing upon the land for- 
ming the borders of the lake, an infertility of aspect which 
vanishes upon passing these sandy limits, ‘The greater portion
