of the lacustrine beds of Lawlor’s Lake may be looked upon as having 
a more northern facies than those of the upper part, or than those 
living in this region at the present day. There is a prevalence in 
the lower part of plants of High-northern distribution, as the Black 
Spruce, the Fir, the White Birch and the small Bog Cranberry. 
The Larch and the Sweet gale come in higher up in the beds and 
the White Cedar, the Water Lily, the Alder and other broad 
leaved shrubs and trees are found still later. But the apparent 
absence of these plants from the lower deposits is not much to be 
depended on as a proof that they were not growing here then ; and 
it is to be noted that the Fir which is of a somewhat more southern 
range than the Black Spruce is found at the base of the deposit and 
must have been growing here when Lawlor’s Lake first emerged 
from the sea. 
In the stunted appearance of the plant remains found in the 
lacustrine clay, there would nevertheless appear to be an indication 
that the plants which grew upon the slopes around the lake when the 
salt-water left it, were not so well nourished as those which clothed 
its margin in later times. The leaves of both Spruce and Fir were 
smaller and the twigs of the Larch were slenderer, and had the 
projecting nodes to which the fascicles of leaves were attached, 
smaller and more closely approximated than in individuals living in 
similar situations at the present day.
