of this sand is yellowish white, but a dark reddish brown variety ~ 
was often seen deposited upon it in continuous ripples at diffe- 
rent but parallel levels; On examining this sand it was found 
to be composed principally of magnetic iron and precious gar. 
net. It is an analagous compound to the emery of commerce, 
and if reduced to a greater degree of fineness, might be employ- 
ed for the same purposes. The rocks here were found to be 
the same as at the last place; they have externally often the 
aspect of old lead, and when broken the faces of the laminz pos- 
Sess alustre which is at the same time almost splendent and semi- 
metallic. Upon commencing operations, Mr. Hamel found 
between twenty and thirty degrees of local attraction, but in 
one spot, free from it, he determined the magnetic variation to 
be 16°. 40’ W. On these rocks ¢ripe de roche is found in some 
abundance; it is of a deep copper brown colour, and agrees well 
with the drawings of it to’ be seen in the appendix to Franklin’s 
quarto edition of his first Journey to the ArticSea. When we 
first saw them they were mistaken for representations of some of 
the native copper ores which he met with among the copper 
mountains. ‘T’o the taste it has the flavour of mushroom, and al 
though meagre it is not unpalatable. The sandy beach here is 
enclosed by two rocky points, forming a bay about fifteen or 
sixteen hundred feet wide, the water in which shoals very gra- 
dually. A sand bank about fifteen feet high encloses this bay 
on the land side, beyond which there is a sandy swamp ; and 
this is descriptive of much of the lake on this side. 
On leaving this bay and proceeding again to the north, we 
doubled the rocky point, which was found to be composed of 
the same felspar before met with, as was also another we round- 
ed soon after, situated at the entrance of an inlet up which we 
ascended mistaking it for the Koucouachime river, and where 
we found avery good soil consisting of a yellowish loam, about 
one foot six in thickness, resting on plastic clay. As the term
