140 Lieut. Baddeley on the geognosy — 
guenay river, particularly in that portion of it between Chi. 
coutimi, and La Buole, from the last of which places, towards 
ghe mouth of the Saguenay, the rocks become more quartoze 
and less amphibolic or hornblendic, and pass from trap and 
syenite into syenitic gneiss and granite. To this latter cause 
may be attributed the comparative narrowness of the river at 
its entrance. 
As Mal-Baie is approached, the rocks are observed to be 
Srowded with veins of trap, felspar, quartz and granite, to an 
excess. These veins are generally parallel to each other, fre. 
quently contorted to a degree that is scarcely credible. In some 
places they are absolutely countless, and being composed of 
different coloured minerals, as white quartz, black horn- 
blende, red felspar, &c., they bestow on the rock at once 
a singular and beautiful appearance, to which an artist alone 
could do justice, as it is totally beyond the power of descrip- 
tion to convey. 
It is worthy of observation, that the granite veins which 
have been described as traversing the rocks, both in the St. 
Lawrence and Saguenay rivers, were found to be composed, 
whenever examined, of large flesh coloured crystals of felspar, 
large pieces of grey or white quartz, and mica in hexagonal 
‘plates, about the size of a farthing, the whole forming a vas 
riety of graphic granite, differing widely in appearance from 
those fine grained granites, which have been described as oc- 
curring in apparently stratified masses in the Saguenay and 
elsewhere, and among the constituents of which it is often 
difficult to say whether mica or hornblende is to be ranked, 
or whether they are not both of them present, the small black 
specks disseminated through the aggregate, resembling either of 
those minerals. The plates of mica in these veins, were ** few 
ing and far between :?’ the rarity of this mineral in the rocks 
under description has been before alluded to. 
A number of recent shells principally echini or sea-eggs are 
found upon the rocks, and sometimes at an elevation, to occa-
