of 1912744, No approximate height could be expected 
from calculating with such imperfect data; they were em- 
ployed, however, and by one calculation, in which 12 miles 
were assumed as the base, the height was found to be 919 feet ; 
by another, in which the base was 10} miles, 805 feet were 
obtained : the former agrees nearly with the result of an obser- 
vation less liable to prove erroneous which was taken subse- 
quently at the post of T'adousac. 
Upon landing at this place (Tadousac) we proceeded imme- 
diately to examine a few of the geognostical characters of the 
country. The only place of residence here is erected on a bank 
of sandy alluvium, elevated about 50 feet above the river, and 
forming a flat terrace at the base of the mountains which sud- 
denly emerge at a short distance behind. The rock of which 
these mountains is composed is granite, either of a red ora 
grey color, depending upon that of the felspar. It contains 
very little mica, but sufficient to make it a genuine granite, a 
rock as will be seen of rare occurrence among those about to 
be described. It crops out in cuboidal masses, and possesses 
sometimes the probably fallacious appearance of being stratified. 
At the foot of this granite, a small stream drains a tolerably deep 
section of the before mentioned alluvium, which is crowded 
with water-washed fragments of crystalline rocks, On the 
shore were seen small deposits of magnetic iron. Here bases 
were measured, and the requisite angles taken for determining 
the height of the most elevated land on cither side the mouth 
of the Saguenay, which was tound to be 912 feet on the west- 
ern side, and 588 fect on that to the eastward. These results 
are approximations only, as the observations from whence they 
are derived, were not taken with the utmost precision. 
Leaving the ha:bour of Tadousac and proceeding to the east- 
ward round the clayey precipice of Pointe-aux-Vaches, which 
is the most southern portion of the alluvial plateau before de- 
sernbed,
