and the greatest amount in 24 hours was 1.92. e report of 
the U. S. Weather Bureau a New York City, for May, 1899,

The herbaceous grounds were most affected by the freezing 
temperature, being enclosed on three sides by wooded areas 
and on the west by a ridge, so that they really lie in a sort of 
pocket, the cold air settling on them and being confined. The 
temperature recorded here was 26 degrees, the lowest indi-
