24 On the prevailing Storms of the Atlantic Coast. 



Nor do we any longer find difficulties in conceiving of the regular 

 progress of the storm from south-west to north-east, as a component 

 portion of the general mass of atmosphere which has previously been 

 tending in that direction. This progress still continues while the 

 stormy mass is revolving around its own moving axis, and we can 

 readily comprehend the violent effects of its unresisted rotation, 

 while this velocity becomes accelerated by nearly all the oblique for- 

 ces, and perhaps resistance, of the circumjacent currents or masses 

 of moving atmosphere. 



In order to give a further history of the storm of 1821, and lest 

 we should fall into the error of adopting a conclusion, which a more 

 complete array of the facts might fail to warrant, we will give some 

 further notice of the first appearance and entire progress of this 

 storm, so far as we have been able to obtain accounts of it. This 

 will enable us to identify its track, and exhibit further evidence of 

 its character as a whirlwind, or, will afford us evidence with which to 

 combat that conclusion, if it be erroneous. 



The earliest supposed trace of this hurricane which has been ob- 

 tained, is from off Turks-Island, in the West Indies, where it ap- 

 peared on the first of September, two days previous to its reaching 

 our coast. It was felt there severely, but at what hour in the day 

 we are not informed. 



The next account we have is from Lat. 23° 43', where the storm 

 was severe, Sept. 1st, from south-east to south-west. Whether these 

 two accounts are considered as identifying the storm, or otherwise, 

 will not, at this time, be deemed material. 



Our next report is from Lat. 32° 30', Lon. 77° west from Green- 

 wich, on the night of Sept. 2d, a hurricane for three hours. 



At 3, A. M. on the 3d of September, a severe gale was experi- 

 enced thirty miles outside of the American coast, ofi' Wilmington, 

 North Carolina. 



At Wilmington there was no gale. 



At Ocracock bar, N. C. at day light on the morning of the 3d, a 

 severe gale from east-south-east. 



At Edenton, N. C. the gale was at north-east. 



Off Roanoke, on the morning of the 3d, a dreadful gale at east, 

 then soudi-west and north-west. 



A vessel from Charleston, S. C. two days previous to arriving in 

 the Chesapeake, experienced the gale at 4, A. M. on the 3d, from 

 south-east to wcst-souih-west.
