the north-eastern side of the river to have a bearing north and 
south, and at Baie St. Etienne alittle higher up, on the south- 
western side, they were seen, contrary to their general habits, 
to retire from the shore and to leave a few acres of clay allu- 
vium, on which wild grassis cut annually. Between Pointe St. 
Etienne and L’Ance aux Foins (another more extensive allu- 
vial deposit higher up) the rocks are particularly worthy of 
observation for the numerous dykes and contorted veins of trap 
by which they are traversed. These rocks are stratified, and 
dip ata high angle to the south. In some places here the trap 
dykes, which exactly resemble those we have described in their 
mineral contents, structure, and generally intrusive or interfer- 
ing character, have the appearance of alternating in strata with 
syenite. The opposite shore of the river offers the same ap- 
pearances, but not having landed there nothing more can be said 
of them. . 
In the precipitous cliffs om the north-eastern shore of the Sa- 
guenay, in the direction of St. Marguerite’s river, these dykes 
are very conspicuous, and from their blackness bear some resem- 
blance to upright beds of coal. It is noticed here, as it is else~ 
where, that where trap most abounds there is always a more - 
dense growth of timber, and this character is sufficiently striking 
in many places on the shores of the river, as the syenite with 
which the trap is usually associated, affords often, by its ex 
treme barrenness, a strong contrast. On one of the islands o 
St. Louis was observed a rock composed of quartz, felspar, and 
mica, a genuine granite in composition, but in evidently strati- 
fied masses, the bearing of which was north and south, with a 
high dip to the westward. 
On ascending the river at Point Comfort Bay, the rocks were 
of syenite, in which a little quartz was perceptible ; external- 
ly they had a greenish colour, owing it is believed to the pre- 
gence of epidote which very wet weather had rendered more 
distinct
