Decrease of the New York Rainfall.

In his report for 1876, Director Draper, of the New York Meteorological Observatory in Central Park, showed that a careful examination of the records in his office proved that there had been, in late years, a change in the rainfall of New York and its vicinity, affecting seriously its water supply. The decrease had been steady since 1869, previous to which there had been an increase. In his report for 1877, Mr. Draper discusses the question whether the change continues, or is likely to continue, in the same direction, and comes to the conclusion that the rainfall of New York will, most probably, continue to decrease by fluctuations for several years to come; also, that the variations are very nearly the same in the two portions of the year, the division date being July 1.
