The number of species found in Nova Scotia is much greater than the 
number occurring in New Brunswick, the deposits of which include many 
spicules of freshwater sponges whose presence may account for the difficulty 
in freeing the valves of an exceedingly tenacious coating which cannot 
always be removed by treatment with alkalis or acids. Comparisons 
might be made with the species found in the Maine, New Hampshire, and 
Massachusetts peat formations which closely resemble those of Canada 
and which are also, to a great extent, found living in the lakes and ponds 
of the New England states. The Glacial flora appears no farther south 
than New Jersey where it still lives to some extent in ponds at Atsion and 
Hammonton and also at Mays Landing. 
The following contains brief notices of the various deposits, and is 
based on information received from Mr. Eardley-Wilmot. 
QUATERNARY DEPOSITS 
Nova Scotia 
(1) McQuade Lake, Halifax County 
A deposit of grey diatomite, 1 to 3 feet thick, occupies an area of 50 
acres on the bottom of the lake. It is covered with a thin layer of mud. 
(2) Sabody Pond, 2 Miles North of East Chester , Lunenburg County 
Grey diatomite, 1 to 3 feet thick, lies uncovered on bottom of the 
pond, for the most part near the shore. 
(3) Sarty Farm, North River, 8 Miles North of New Germany, Lunenburg 
County 
A few inches of grey diatomite overlain by 1 foot of soil. 
(4) South End of Island in Loon Lake ( North of Rossignol Lake), Liverpool 
River, Queens County 
A few inches to 4 feet of grey, yellow, and white diatomite containing 
much sand overlain by about 1 foot of peaty matter. Deposits occur 
on the islands and shores of the lake over a length of 2 miles. A second 
sample from a deposit on the east shore of the lake consists chiefly of sand, 
but contains Cyclotella comta, Eunotia major, Melosira distans, and Tabel- 
laria fenestrata. 
(5, 6, 7) Little River , Digby County 
The deposit consists of 2 to 4 feet of grey diatomite, underlain by 
4 to 8 feet of peat-bearing diatoms, beneath which is 6 to 8 feet of “diatomite 
ooze.” It is overlain by 1 foot of soil. The deposit underlies several 
hundred acres of marsh. Sample No. 5 is of the upper part of the deposit 
(4 to 8 feet down), No. 6 is of the “diatomite ooze” (10 to 20 feet down), 
and No. 7 of the peaty part.
