106 PHILOSOPHY OF STORMS. 



It is also worthy of particular remark, that the wind at 

 Emmettsburg was north west on the 21st, blowing towards 

 a region where it rained that morning and the preceding 

 night, so much as to do great mischief, and even as near 

 to Emmettsburg as Baltimore, it rained in that time 1.7 

 inches. 



This rain reached Emmettsburg, but was small in quan- 

 tity, viz. j 2 ^ of an inch. The wind on this day, at Balti- 

 more, varied from south east to north east. It was, there- 

 fore, part of the time, exactly opposite to the wind at 

 Emmettsburg. 



Another remarkable feature of this storm is, that it was 

 preceded the day before with thunder gusts, on the north east, 

 north and west, and probably on the south east, as the tem- 

 perature fell very suddenly at Philadelphia, as soon as the 

 wind changed to south east, about eleven, A. M. The sudden 

 depression of temperature can hardly be accounted for, ex- 

 cept on the supposition that a thunder storm took place 

 during the preceding night, south east of Philadelphia. 

 The temperature had not changed at Harrisburg, at one, 

 P. M., nor at Emmettsburg at half past two, where the 

 wind continued all day from the south west. 



Besides these two storms, we may mention one which 

 took place on the night of the 10th March, 1836. The 

 centre of greatest rain appears to have been at Providence, 

 R. I., where it began at six, P. M., and rained most vio- 

 lently till twelve at night. The papers of the day give 

 accounts of great damage done by the floods near Provi- 

 dence ; and they state that the wind sprang up and blew 

 violently from the south east, at Bristol, R. I., some time in 

 the evening, and raged from that quarter till five next 

 morning, and then changed round to south west, and con- 

 tinued strong. 



At Flushing, Long Island, the wind was almost calm at 

 three quarters past five, P. M., but about seven it rose from
