106 Lieut. Baddeley on the geognosy 
the river on the same side, it was seen frequently again under 
all the forms before-mentioned. Sometimes the trap, rising 
in black channeled precipices entirely bare of vegetation, exhi- 
bited appearances in which a very distant resemblance to archi- 
.ectural regularity might be traced. Sometimes a part of the 
rock having broken away from below, black escutcheon-shaped 
masses were left projecting and frightfully pendant over the fra- 
gile canoe paddling beneath near the base of the rock : the lat- 
ter appearance, however, is more characteristic of the opposite 
shore. No columnar structure was seen, but in many other 
places in the Saguenay as wellas here, the rocks had a tenden- 
cy to break into prismatic or cuboidal fragments. We believe 
the trap is in this place associated with syenitic gneiss, with 
which or syenite it appears sometimes to alternate, On ascend- 
ing still further, and within a few miles of Chicoutimi, a whitish 
looking rock was observed, apparently in horizontal strata ; pass- 
ing at some distance nothing more was ascertained respecting 
it. To this succeeds an alluvial deposite of a rich marly clay, 
which continues on the right bank as far as the Post. On the 
left bank of the river the rocks continue without interruption, 
and without any geognostical change, as was ascertained subse- 
quently. 
Before we leave the Saguenay a few more observations upon 
its rock formations, which were entered in our journal while 
descending the river on our way home, will be here introdu- 
ced, together with some additional information which Mr. 
Proulx’s politeness has placed at our disposal. 
La Baie des Foins, situated on the left bank of the Sague- 
nay, alittle below the Post, is a natural meadow of several 
acres extent, laying at the base of the mountains which here 
retire for a short distance from the river. The soil is a clayey 
alluvium, and, as the name of the place indicates, wild hay 
grows uponit which is annually cut. At Long Point, a little
