At Auburn the years 1836, 1837 and 1838 cover a period of very 

 low precipitation, as shown by the following : 



1836 1837 1838 



Storage 19.41 10.37 7.50 



Growing 6.39 11.35 8.14 



Replenishing 6.56 6.78 6.05 



Total 32.36 28.50 21.69 



. Taking into account the sequence of the foregoing record at 

 Auburn, it is probable that in the water year 1838 the runoff of 

 streams in that vicinity did not exceed 3 to 4 inches on the catch- 

 ment area. 



In view of its relations to the runoff of the Upper Hudson catch- 

 ment area, we may refer to the record at Burlington, Vt., for 

 the years 1893-1896, inclusive. We have the following from the 

 Burlington record: 



1893 1894 1895 1896 



Storage 8.63 10.35 10.70 9.70 



Growing 13.78 4.51 10.08 11.05 



Replenishing 5.25 8.34 8.19 8.55 



Total 27.36 23.20 2S.97 29.30 



Taking into account the low precipitation of 1894, it is prob- 

 able that in 1895 and 1896 streams in the vicinity of Burlington 

 did not run to exceed 5 to 6 inches on the catchment area. 



At Cazenovia the two lowest consecutive years are 1834 and 

 1835, when the total rainfalls were 34.29 inches in 1834 and 32.82 

 inches in 1835. Inasmuch as streams in that vicinity fall in the 

 same category as the Genesee river, if we assume similar con- 

 ditions of forestation, the runoff was probably about 8 inches on 

 1 he catchment area. 



At Cooperstown the mean precipitation for the period from 

 1854 to 1898, inclusive, is 39.07 inches. The three consecutive 

 minimum years occurred from 1879 to 1881, inclusive. The fol- 

 lowing are the precipitations for those years :
