exceeded 5 or 6 inches. These conclusions, it must be understood, 

 are based on present conditions of forestation. In case there 

 were much larger forest areas in that vicinity at that time, the 

 runoffs may have been somewhat larger. 



At Mexico the total precipitation for the year 1840 was 20.21 

 inches, the storage period of that year being 9.73 inches. The 

 runoff probably did not exceed 2 inches. 



At Mount Morris the total precipitation of the year 1891 was 

 23.69 inches, that of the storage period being 10.24 inches. In 

 1895 the total was 25.05 inches, the storage period giving 11.95 

 inches. From the writer's personal knowledge of the subject he 

 has no hesitation in saying that in 1895 streams in the vicinity 

 of Mount Morris did not run to exceed a total of about 3 to 4 

 inches. 



The year 1895 was generally a year of low precipitation 

 throughout the whole State. Thus, at Newark Valley the total 

 was 28.40 inches; at New Lisbon, the total was 29.93; at North 

 Hammond, the total was 29.80, and so on. An extended analysis 

 of the precipitation records shows that for a large portion of 

 the State of New York the runoff of 1895 did not exceed 6 to 12 

 inches on the catchment areas. At some places the runoffs were 

 less than 6 inches. At Onondaga Hollow the year of minimum 

 precipitation occurred in 1841, having been preceded by several 

 years of rather low rainfall. Streams in that vicinity probably 

 do not exceed 6 inches runoff in years of minimum precipitation. 



At Oswego the precipitation sank to 2G.15 inches in 1855 and 

 to 23.46 in 1887; in 1889 it was 30.39 inches. In 1887 the total 

 for the storage period was 10.55 inches. It is doubtful if the 

 runoff at Oswego exceeded about 2 to 4 inches for that year.
