The low precipitation of the storage period of the water year 

 1834 indicates runoffs in the vicinity of Oxford for that year of 

 perhaps 5 inches. 



At Palermo, where there is a continuous record from 1854-1898, 

 inclusive, there are several years in which the precipitation is 

 given considerably below 30 inches, as for instance in 1871. 27.81 

 inches ; in 1875, 28.11 inches ; in 1881, 26.37 inches ; in 1882, 28.8G 

 inches, and in 1895, 25.97 inches. The precipitation of the 

 storage period of 1895 was only 10.15 inches. It is probable that 

 for that year streams in the vicinity of Palermo did not exceed a 

 runoff of 2 inches. 



At Penn Yan there is a continuous record from 1829-1867, 

 inclusive, the mean of the whole period being 27.93 inches. 

 There are several periods of from three to six years when the 

 rainfall was less than the average. So marked is this that it 

 seems safe to assume that streams in the vicinity of Penn Yan 

 do not ordinarily run more than from 4 to 6 inches on the catch- 

 ment area. In 1854 the total precipitation was 19.66 inches. 

 There are several years in which the total precipitation at Penn 

 Yan for the storage period has not exceeded from 8 to 9 inches. 



At Pierpont Manor the totals for the years 1852-1854 are as 

 follows: 1852, 30.93 inches; 1853, 27.57 inches, and for 1854, 

 28.89 inches. In 1862 the total precipitation was 28.15 inches. 



At Plattsburg the total precipitation in 1858 was 2!). 11 inches 

 and in 1859, 22.78 inches. In 1893 it was 25.69 inches, with a 

 total of only 9.92 inches in the storage period. For 1895 the 

 total was 29.75 inches. It is evident that the minimum runoff of 

 streams in the vicinity of Plattsburg does not exceed 6 inches. 



At Pompey the totals for the years 1836-1838 arc as follows: 

 For 1836. 24.22 inches; 1837. 28.37 inches, and for 1838. 24.82 

 inches. 



At Port Ontario the total precipitation for 1855 was '26.15 

 inches; for 1871, 29.76 inches, and for 1872, 28.81 inches. 



At Potsdam we have the following record for the years 1837-
