distinct and lively than usual. These rocks possessed a very 
distict appearance of stratification to the north and north-east, 
and dipped to the east and south-east ; other contradictory 
planes were however seen, Many of the rocks in this bay pos- 
sess a porous exterior. 
At nine o’clock of the 12th August the temperature in the 
shade was found to be 71° Far. and in salt or very brackish wa- 
ter 650. With the conjectured distance of five hundred and fif- 
ty feet asa base, and nearly 45° as an elevation, a height of five 
hundred and thirty feet was. obtained for a mountain on the 
north-eastern shore. On the opposite or south-western side the 
summit of a mountain, ina supposed base of two miles, subtend- 
ed an angle with the horizon of 7° 27° 54° which gives thir- 
teen hundred and sixty feet for its perpendicular height, a re- 
sult as we think much too considerable, although the land ap- 
pears to rise from the mouth of the Saguenay as high up as Baie 
la Trinité, where it is conceived to be highest. The precipi- 
tous and indented shores of this river afford few convenient situ- 
ations for measuring a base upon, in order to insure, by acalcu- 
lation from true data, the accuracy of this sort of information, 
Having landed a little above la Baie des Cascades, a syenite, 
composed of reddish felspar and a black hornblende, was found, 
zenda short distance beyond, the same rock, characterized by 
thoseremarkable imbedded pieces of trap, occurs ; they have here 
either the form of a snake or of angular fragments of an irre- 
gular figure ; contorted dykes of the same substance were also 
seen, The trapin this instance contained no mica; in other 
respects it was exactly similar to that before described. About 
this place the river was measured by Mr. Proulx, one of the 
Surveyors, and found to be about fifty chains, One of the spe- 
cimens of syenite procured here, appeared to be principally 
composed of light brownish compact felspar ; its fracture was 
fiatly conchoidal in the large, but uneven and scaly in the small,
