14 PHILOSOPHY OF STORMS. 



some, four, and in others five and six inches of rain ; during 

 all this time the wind at Philadelphia was south : at the 

 south east corner of New York, it was south east, and in the 

 most northern counties, it was three of these days con- 

 stantly north. At Philadelphia and in the south east parts 

 of New York there was no rain when the wind was uni- 

 form, but in the most northern counties there was some rain, 

 but. not so much as in the central parts. The rain extended 

 beyond the east and west boundaries of the state, and there 

 the wind was variable ; prevailing, however, in the east, 

 from the east, and in the west, from the west.

 1.47 inches at Nashville, the wind was blowing at Philadel- 

 phia towards Nashville, and when this same storm reached 

 Philadelphia, which it did in twenty-three hours, the wind

 changes round by south, and when the centre of the storm 

 passes to the south of us, the wind changes round by 

 north. 



31. On the22d March, 1835, from eleven, A. M., till one, 

 P. M., it was very calm, with a low barometer, but very 

 dark, with thick clouds, which appeared to be almost sta- 

 tionary. The wind had been north east in the morning, 

 with a little rain; during the hours in which there was a 

 calm and no rain at Philadelphia, there was a most violent 

 wind at York, Pennsylvania, towards Philadelphia, and 

 also a very great rain ; the same at Baltimore. At Cape 

 Hatteras there was wind towards Philadelphia, and rain in 

 sight towards the north east. At Flushing, New York, the
