ON CANADIAN PLEISTOCENE FLORA AND FAUNA. 413 
clay was met on the side towards the river, with numerous small angular 
pebbles of shale and an occasional one of syenite. At 16 feet stratified 
elay with some pebbles of shale replaced the boulder clay, going down 
5 feet, when boulder clay again came in to the thickness of 2} feet and of 
typical character, containing boulders of limestone and granite. Below 
this a little stratified clay was found, and then sand until the shaft was 
stopped at a depth of 27 feet. 
An opening made on the hillside below showed about 6 feet of sand 
followed by 10 or 12 feet of gravel overlying stratified peaty clay. This 
shaft gives evidence that the upper boulder clay overlies the strati- 
fied sand and also the peaty clay as at Scarborough Heights, and so com- 
pletes the proof that the cold climate beds and the underlying Don beds, 
with unios, leaves, and wood of a warm climate, lie between sheets of till, 
and are interglacial. 
Summing up the work done, we have the following section near the

It is found that the top of the peaty clay is about 15 feet lower on 
the side of the hill towards the Don than on the western side near the 
tributary ; but on both sides it is covered with interglacial sand and 
gravel as at Scarborough Heights, the latter point being unknown before 
the shafts here described had been sunk. 
The thanks of the Committee are due to Professor A. B. Willmott for 
taking charge of the work during the absence of the Secretary, and to the 
Messrs. Taylor for their kindness in permitting the shafts to be sunk on 
their property. 
A considerable amount of material, such as fossil leaves and wood 
obtained during the work and from Taylor’s brickyard, has been forwarded 
to Professor Penhallow for identification, but time has been wanting for
