made water-tiglit the numerous basins formed by the 

 transverse moraines and gravel ridges that existed in 

 these valleys. In this way innumerable lakes were 

 produced, and it became the business of the rivers, as 

 the land emerged from the sea, to unite the various 

 lakes together, to erode the barriers, drain the depressions 

 and restore the river svstems aeain. 



It sometimes happened that these gravel and boulder- 

 clay barriers were so extensive and high that the river 

 was forced to seek a new channel, and usually a rocky 

 one, often removed to a considerable distance from the- 

 one it had occupied before the Glacial period. Such was 

 the case with the St. John, both at Grand Falls and at 

 its present outlet. 



The conformation of the land between South bay 

 and Pisarinco cove renders it highly probable that this 

 was the course by which the river discliarged its waters 

 into the sea before the Glacial period. The shores are 

 low around l)oth these indentations, and only a few
