As further showing that the upper Mohawk — the portion above 

 Little Falls — must be. so far as delivery in the broad level valley 

 is concerned, a relatively rapid stream, we may consider that this 

 division of the catchment area is quite narrow, being at the 

 extreme western end about 45 miles and at Utica about 25 miles. 

 On the north side of the valley Black river canal, following the 

 general course of the river and its chief tributary above Rome, the 

 Lansing kill, rises to an elevation of 1200 feet on the Boonville 

 summit in a distance of 25 miles. To the south of Utica the aban- 

 doned Chenango canal, following a circuitous route, reaches an 

 elevation of 1126 feet on the Bouckville summit in a distance of 

 about 24 miles. 



The mean elevation of the Mohawk valley proper, from a short 

 distance above Little Falls to Rome, may be taken from about 380 

 to 120 or 430. A1 Rome, above the feeder dam. the elevation of the 

 water surface above mean sea level is 430.5 feed ; at the New York
