26 Captain Bayfield on the 
habitation of a Manitou or Spirit. This island is of conglo= 
merate. The north-west side of Point Keewawonan is prin- 
cipally of conglomerate, which is in general the lowest stratunr 
of the sandstone formation to which it belongs, Sandstone and 
conglomerate however, that is fine and coarse sandstone, not 
unfrequently alternate with each other. Points of trap green 
stone are common, and almost all along this side of the point, 
there are parallel chains of small trap islets close to the shore, 
very like those of [le Royale, which is distant about 41 miles 
to the northward. 
Further to the south west, points of sandstone cliffs and 
sandy bays between, occur as on the south east side. 
We never met with amygdaloid in place, on this promontos 
ry : we however think it very probable, that itmay be found 
there, for of course we could not land every where. That 
rock is very plentiful among the debris of the beaches, con- 
taining almond shaped nodules,: of calcspar encrusted with’ 
green earth, also agates, carnelians, and native copper. 
Small pieces of malachite associated with calespar, were also 
met with occasionally ; but never very distant from the los 
eality of that mineral, which we are about to describe. 
About seven miles westward from the north east extremity 
of point Keewawonan, on the east point of Copperas Harbour, 
there is a vein of copper ore (malachite) 5 or 6 feet wide, and 
in the oldred sandstone, which it traverses in a north and 
south direction nearly. Itis rich in ore, and can be perceiv- 
ed running along the bottom of the lake, under water, until 
the depth hides it from view. To a person in a boat or 
vessel close in shore, it appears likea large bluish green rock 
en the beach. 
23. Doctor Bigsby has written so fully upon the trap and 
other veins which traverse the granite and greenstone, that we 
shall not dwell on the subject. We must however remark, 
that we have never noticed a vein of trap passing fromgranite 
into
