The preceding discussion shows that while the Genesee river 

 record is a composite one, nevertheless it is believed to be a 

 good record. The reason for this belief is largely founded on 

 the curve as per fig.ll. 



Gagings have also been kept at Mount Morris from June to 

 December, 1890, and at Rochester from March, 1893, to the 

 present time, but the gagings at Rochester are not very reliable. 

 Possibly some method of correcting them may be worked out in 

 the future. 



In table' Xo. 48, a comparison has been made of the measure- 

 ments at Rochester with those at Mount Morris for the water 

 years 1894-1896. inclusive.
