between this place and Le Petit Saguenay, and it should in- 
timate the propriety of never naming a rock in general, until at 
least its fractured surface has been seen; decided trap was 
however often met with in this interval, either in stratified mas- 
ses, ‘or intruding among other rocks, 
In passing between the St. Louis Islands and the south 
shore, we were obliged to take refuge from the breakers, which 
threatened to swamp our canoe, by climbing up a projecting 
mass of greyish granite, on which the night was passed, The 
mica of this granite was replaced as usual by hornblende, it was 
therefore syenitic; the former mineral being in all the rocks of 
the Saguenay country we have seen, very rare and almost entire- 
ly confined to some specimens of the trap, in which it occurs 
in small quantity and minute scales, and this indeed appears to 
be rather talc than mica, as it is unelastic. Weonly remem- 
ber to have seen very distinct scales of micatwice; in both ca- 
ses they were isolated hexagonal crystals, and one of them oc- 
curred in a vein of graphic granite composed of beautiful large 
fiesh-coloured crystals of felspar and large rounded, or rather 
oval shaped, nodules of quartz, traversing the last-mentioned 
rock, Our observations of the geognosy of the Saguenay ri- 
ver terminated here. 
From an inspection of Mr, Proulx’s notes, and an examina- 
tion of the accompanying specimens, the following additional in- , 
formation has been obtained. 
_ The rocks in the neighbourhood of Ha-Ha Bay are counter- 
parts of those already described in the Saguenay, and the same 
were seen at Point au Fort, Cap a l’Quest, Petite Pointe, Cap 
St. Charles, L’Ance Francois and Baie St. Jean. They are 
rocks in which felspar and hornblende are always present, in a 
greater or less proportion, forming syenites and syenivic traps, 
according as the former or the latter mineral predominates. No 
instance of the hornblende predominating was seen, except in 
the
