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 
é 
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. Ist, 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 materi 
Our next report is from Lat. 32° 30’, in 77° west from Graal 7 
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 shiiey miles outside of the American coast, off Wilmington, 
North Carolina. 
At Wilmington there was no gale. 
At Ocracock bar, N. C. at day light on the morning of the 3d, @ . 
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 south-west and north-west. 
A vessel from Charleston, S.C. two days previous to arr a in 
the Chesapeake, experienced the gale at 4, A. M. on the 3d, from 
south-east to west-south-west.
