Fisher. — River Terraces. 
PLATE 7. 
Plates 7, 8, 9 show that the West River, during the later stages of its de¬ 
grading, has swung between nodes determined by rock barriers at the Pump¬ 
ing station and at the junction of the West River with the Connecticut. The 
right-hand swinging has been, in general, accomplished by the partition 
process, and the left-hand swinging by the more direct short-cut process. 
Plate 7 illustrates the possible terrace pattern of the West River valley at 
the time when the river made the left-hand swing at the 225-217-foot level.
