Some cases, we are aware, can be quoted where the direction on very elevated ground 

 is more nearly north and south. And the cases are numerous, as the table we have given 

 will show, where it is as much deflected towards the east as in the above table, in the 

 lower and more level parts of the State. A part of these cases we explain by the 

 supposition of ancient glaciers following down the valleys; other cases show the modify- 

 ing influence of valleys, of which the valley of Winooski River is a striking example. 

 And then if icebergs did the work, we might expect that some of the largest would reach 

 the surface of the low and level parts of the country when the ocean was the highest. 

 But upon the whole we cannot doubt that one of the predominant and most powerful or 

 the striating agencies took a south east direction. Any one conversant as a geologist 

 with the west side of the Green and Hoosac Mountains, must have been struck with the 

 strong marks exhibited by their western slopes of the mighty force that must have long 

 beaten against them, covered them with detritus, and scored their surface. No ridges 

 that we have ever seen in New England show any such marks on their eastern side. 



2. FKOM THE NORTHEAST. 



The evidence is much less striking, of a drift agency coming from the northeast across 

 Vermont and Massachusetts than from the northwest. Nevertheless, we have discovered 

 too many cases of a force from that direction and passing over some of our highest land, 

 to be able to refer it to ancient glaciers or local deflection. We quote the following cases : 



Mansfield Mountain, stoss side of some ledges on the Chin, about . . N. 40 E. 



Marlboro, high land, . . . . . . . . N. 38 E. 



Morristown, . . . . . . . . . N. 30 E.

Putney, . . . N. 20 E.

Southampton, Connecticut valley, sandstone, ..... N. 60 E. 



Granville, 1240 feet high, . . . . . . . . N. 60 E. 



Most of the above cases occur along the eastern slope of the Green and Hoosac Moun- 

 tains, so that a force coming from the northeast must have urged the materials obliquely 

 up hill, since these mountains coincide nearly with the meridian, and the northeast side 

 must have been the stoss or struck side and such we find to have been the case. Perhaps
