He has been assisted in the field-work by Professors Clendenin and Spillman, and arrived at the conclusion that the North American Continent was at least 1, 200 feet higher when the submerged channels to be found near the coast were formed than it is now. The Valley of the Lakes is bounded by high escapments upon its southern or right side, some of which are now submerged. The glaciation of the country varies from 15 to 90 degrees from the trend of these bounding walls, and radiates more or less from the western and southern ends of the lakes. The vertical faces cf the escarpments, often of a considerable height, arc not glaciated as are the walls of Alpine valleys, and Professor Spencer considers this one proof that the old valleys were not fashioned by glaciers. He considers that the modern separated valleys of the lakes are the representatives of the ancient valley of rhe St. Lawrence and its tributaries, whose appearance has been changed by drift deposits, which in some cases has contributed to the formation of the barriers between the different lakes. But the rocky boundaries of the basins which retain the waters of the lakes have been mostly lifted up since the time of the formation of the upper boulder clay, as the lakes are all posterior to that epoch. These conclusions are proved by the fact that the high level beaches of their former expanded waters rest upon such deposits, and that these beaches rise towards the north and east. There is but little unequal continental elevation at the western end of Lake Erie--about 2 feet per mile at the eastern end, and 5 feet per mile at the outlet of Lake Ontario, the direc. . .
