country about the Montmoienci. 185 
The limestone passes into sandstone on the east of the falls 
within a hundred yards of them, and it is said it there termi- 
nates. Atthepoint B. (in No. 2.) where there is a lime 
kilo within that distance, the limestone, (although still retain- 
ing that name, ) is considered as not fit for the kiln, which 
is supplied with a better material from other parts of the 
same field nearer the Falls. 
The principal extent of the limestone, is to the west of the 
Falls ; and at jts western limit, it joins clay-slate. To the 
north it is interrupted by a chain of mountains of gneiss which 
appears to emerge from beneath it, and to be part of the rock 
over which tho Montmorenci rushes. So much of these 
mountains asis visible from Quebec, forms a ridge of which 
the general bearing from that place is through all the points 
between N. W. and N. E. The lower summits are the north 
western, and the more elevated are at the N. E. The loftiest 
ascertained point in this tract anpears to be that of Cape 
Tourmente, 2000 feet above the St. Lawrence where it flaws 
along the base of that mountain. This chain encircles many 
lakes and fertile vallies: yet its northern serics is imperfectly 
known to the Buropean race. It continues to be the hunting 
ground of the Hurons of Lorette. Along the hither, or south- 
ern line of their base—and not higher, so far as is known —the 
soil contains imbedded shells, among which those of this 
form and size are the most common. (see fig. 7. a.) This is 
also true of other parts of Beauport and of Charlesbourg and 
Lorette. Through those parishes (adjacent to each other) 
the limestone formation continues. At the west of Begq- 
port it recedes from the course of the St, Lawrence skirting 
the southern line of the base of the mountans hefpre mene 
tioned through those parishes, and thence declining to the 
level of the Saint Lawrence which it meets at Jacques Car» 
tier in Cap Santé near a place where the river Jacques Cartier 
rushes through a narrow gorge in that rock. In this tract the 
Limestone has continued through eyery level from that of the 
X 2 St.
