PHYSICAL HISTORY OF NEW HAMPSHIRE. 



541 



The ice in this period pursued a south-easterly course, with a reckless 

 disregard of all obstacles. Mountains were scaled by the resistless mass, 

 as is proved by the ice grooves running from base to summit, while the 

 south-easterly slopes show scarcely any marks of scarification. 



Second, nearly all the ice south of the White Mountains and cast of 

 the Connecticut basin pursued a southerly course. Mts. Monadnock, 

 Kearsarge, and Ragged stood up as islands in this ice sea.

[This illustration should be compared with Fig. 63, which shows the back side of the same mountains, as seen 

 from Jefferson hill. In the first instance, the more gentle slope on the north side shows the smoothing, rounding 

 action of the south-easterly moving ice ; while, in the second, precipitous sides illustrate the fact of no erosion by 

 the great continental glacier. As the force moved south-easterly, the ice would not act upon the south-eastern or 

 lee sides of the mountains.] 



Third, in the Connecticut valley south of Columbia, both in New 

 Hampshire and Vermont, the ice moved a few degrees west of south, 

 corresponding" with the general course of the valley. 



Fourth, a similar current passed down the valley of Baker's river to
