New York has an area of 789 square miles. The area of the river 

 itself from its head at Lake Erie to the falls, is 21 square miles. 1 



The accompanying table gives the precipitation within and in 

 the vicinity of the catchment area of the Great Lakes for the years 

 from 1892 to 1895, inclusive. In this table a few only of the 

 many precipitation records which are now available have been 

 used. The records here appearing are, it is believed, sufficient to 

 show the mean precipitation of the basin of the Great Lakes for 

 the 3'ears indicated. In this table the monthly precipitation has 

 been omitted, as it can readily be found in the annual reports of 

 the United States Weather Bureau, and the data have been con- 

 densed to show the total quantities for the storage, growing and 

 replenishing periods, together with the total annual quantity.
