by fifty feet of stratified sand, covered by a bed of 
till varying from forty feet to nothing in thickness. 
Three miles from Victoria Park this layer of till 
suddenly dips down to the lake, thickens to sixty 
or seventy feet, and rises as suddenly a quarter of a 
mile farther east. The hollow left on its surface is 
filled with stratified clay to a depth of ninety feet, 
and this is followed, where the escarpment is high- 
est, a half mile farther east, by from seventy to one 
hundred feet of stratified clay and sand, capped by 
twenty or thirty feet of an upper till. About one 
hundred feet of stratified sand overlying the western 
end of the lower sheet of till, should perhaps be 
correlated with this, though possibly of post-glacial 
age. These sands thin out to nothing where the 
upper stratified clay shows itself. The accompany- 
ing diagram, in which the heights are exaggerated 
tenfold, will give a general idea of the section and 
make a more elaborate description unnecessary. It 
will be noticed that the lower bed of till dips down 
to the lake at each end of the section; while the 
upper till, forming the surface of a table land which 
comes out to the escarpment for a short distance 
only, is cut off abruptly at each end. 
Examining the members of this section in ascend- 
ing order, we find at its base a series of bluish-gray 
clays rising out of the lake. They lie perfectly 
horizontal, are often finely laminated with sandy 
partings, having sometimes twenty lamine to an 
inch, but at other times forming beds several feet in 
thickness. Narrow bands of flat green concretions 
of impure carbonate of iron occur at various levels; 
and at others thin layers of peaty matter. Some 
beds of clay richer than others in plant food may 
be followed long distances by the eye as bands of rich, green 
vegetation, while other parts are bare.
