of Glens Falls, 6 inches. In 1884 the precipitation of the stor- 

 age period was 2.90 inches greater than in the preceding year, 

 bnt this small additional precipitation was probably mostly 

 without effect on the streams because of low ground-water. 

 It appears, therefore, entirely safe to assume that the runoff of 

 streams in the vicinity of Glens Falls must have been quite as low 

 in 1881 as in the previous year 1883. 



At Gouverneur the total precipitation of the year 1838 was 

 20.93 inches; of 1839, 18.87 inches, and of 1842, 17.06 inches. 

 Assuming forestry conditions at that time in the vicinity of Gou- 

 verneur substantially as they now exist on the Hudson river catch- 

 ment area, the runoff of the streams may have been 3 inches, or 

 from deforested areas probably 2 inches. 



At Ithaca the two lowest years of precipitation are 1884 and 

 1895, in both of which the total happens to be 26.98 inches. In 

 1846 the total of the storage period was 9.67 inches, the total 

 for the year being 30.07 inches. It is probable that the extreme 

 minimum runoff in the vicinity of Ithaca does not exceed 5 inches. 



At Keene Valley the lowest precipitation recorded occurred in 

 1881, the total for that year being 28.20 inches. The precipita- 

 tion of the storage period was 13.15 inches. The totals of the 

 previous years, 1879 and 1880, were 32.15 and 33.32 inches, re- 

 spectively. The runoff for 1881 probably did not exceed 8.9 inches. 



At Lowville the period of lowest precipitation was for the 

 years 1843-1846, inclusive. The following are the figures for those 

 years :

A marked peculiarity of this Lowville period is the low pre- 

 cipitation of the storage period for all the years included. Takiig 

 this into account, it is probable that for the years 1845 and 1846 

 the runoff in the vicinity of Lowville was very low. In 1845 it 

 may have reached 8 inches, but for 1846 it is doubtful if it
