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 Pemigewasset 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.
