ing of the barrier in various parts and a commencemient of many 

 north-eastward flowing streams. 



3. At the same time as i, the formation of a series of terraces 

 in the area of Lake Ontario at a lower level than in the above. 



4. The somewhat sudden stoppage of the growth of these 

 terraces due to removal of a barrier of rock at the Thousand 

 Islands. 



5. Establishment of the present levels of land and water. 



6. It may be noticed that since recent shells have been found 

 in the beds of Goat Island, and in those along the Niagara River — 

 and also, since in the brown clays of Walsingham Township, Norfolk 

 County, underlying the sand, the writer has found leaves of the red 

 maple, the birch, the poplar and several willows — therefore, geologi- 

 cally speaking, the time occupied in the development of the above 

 must have been very recent. 



Lastly, the above must be taken to be a first crude summary 

 rather than a finished detail — a suggestive or would-be suggestive 

 outline, rather than an exhaustive picture.
