Modified Drift along Contoocook River. 



The modified drift of Contoocook river, mapped on Plate V (p. 96), has 

 been explored for a distance of forty miles from the east line of Jaffrey to 

 its mouth. This is the largest tributary in the state. It gives the best 

 example found within our limits of a long valley descending from south 

 to north. The upper twenty-five miles of the distance explored has a 

 quite straight course a few degrees east of north. At Henniker the 

 river turns eastward, and thence flows slightly east of north-east fifteen 

 miles to its junction with the Merrimack at Fisherville. These distances 

 measure the direct course of the valley, not the meandering channel of 

 the river, which exceeds fifty miles. 



From the northward course of this valley, we should suppose that the 



* These heights were determined by levelling from Franklin station by Winnipiseogee lake to Ashland, and 

 thence along Peraigewasset river to the point of beginning. By this complete circuit they were proved to be 

 correct, as compared with the altitudes given in Vol. I, p. 258, and also here, for Franklin and Concord.
