tentional injustice is usually closely followed by its appropriate 
Nemesis. 
The assumption that Glaciation, or the superincumbency of an 
ice-covering of vast thickness and immense pressure, in an age long 
since past, would give a clue to the explanation to some peculiar 
phenomena that continually attract notice in a survey of the undu- 
' Jating valleys and hills of our local scenery, the universal distribu- 
tion of boulders of various sizes, and differing much in their mineral 
composition, causes frequent comment and excites curious enquiries 
among land tillers, road makers and others, and to read the descrip- 
tions of travellers and explorers of Alpine regions, such as have 
lately been published in Govermental reports regarding the formation 
of so-called ‘‘ Moraines” by the downward motions and melting of 
vast ice accumulations in the elevated valleys in the Canadian 
Northwestern Territories, as our knowledge of such remarkable 
natural processes has become more precise and accurate, we may be 
better able to judge and to guide one’s thoughts towards a solution 
of problems that have at times appeared inexplicable. 
Prof. Agazzis was said to be one of the first theorists to an- 
nounce (nearly seventy years ago) that, in his opinion, the numerous 
swampy depressions of the general level in North America had 
their origin in stranded glaciers, towards the break-up and termina- 
tion of a glacial epoch, conjectured to have existed all over the 
temperate latitudes of North America many thousand years since. 
That eminent scientist stated that in numbers of ice choked up 
valleys in the Swiss Alps, glaciation was continually to be seen pro- 
ducing changes in the earth’s surface identical with the condition of 
much of the agricultural areas of North America. 
In many parts of Canada where level rock surfaces happen to 
be exposed there can be seen ‘‘Strie” (so called) or glacial 
“‘scratchings,” indelibly grooved into the face of the hardest rocks. 
Many of these peculiar “‘ testimonials” are to be seen on Lake Erie 
shore, near Selkirk, near Kingston, on Lake Ontario shore, and in 
innumerable other localities. 
At the edges of almost all our swamps heaps and ridges of 
rounded gravel of greater or less degrees of fineness exist, sore ot 
them thirty to forty feet high, and usually having one perpendicular 
side, as if deposited against an upright, solid, resisting rampart,
