The rocks at the Post of Chicoutimi, like most of those we 
have described, are syenitic ; the chapel stands upon a syenitic 
granite, passing sometimes into syenitic gneiss ; this rock is tra- 
versed in a remarkable manner by veins of felspar and trap. 
The trap, however, is generally seen in broad bands forking 
into the adjoining rock, which is either syenitic granite, or sy- 
enite having its felspar greatly in excess. Weather acts more 
readily upon the trap than upon the granite, and in consequence 
many of the veins or dykes are partially empty near the surface. 
The same was observed in other places. To this cause are pro- 
bably owing the numerous baysin the Saguenay, as trap rocks 
were more generally found where they occur, while syenitic gra- 
nite and syenitic gneiss occupy its capes and headlands. A 
few imbedded nodules of magnetic iron were observed in the 
rock. Svmetimes the quartz is absent when it loses the term of 
granite, and maintains that alone of syenite, in which the fel- 
spar is red and the hornblende greenish black. There is on 
the shore below the residence at the Post a curiously contorted 
vein of trap which descends the rocky bank, as represented 
in plate 7, fig. 6. . 
Detached pieces of felspar of a very crystalline aspect and of 
a dark purplish grey colour were frequently seen upon the shore ; 
the 
+ To this cause also may be attributed the unusual fact, that almost the 
narrowest portion of the Saguenay is at its entrance, where the rocks are 
more sileceous and less amphibolic.
