the south-east ci'irent (irom the 3d to the 7th) to force its 

 way alonr tVoai iV;bago and Barbadoes to Augustine, Sa- 

 vannah, and Charleston. In hke manner, by comparing 

 the iimcs of its coninnenccmcnt along the Fredish coast, it 

 is evident that the north-east current ble^^ violently near 

 the Frvi 'g-pan s'.oals at half past two P.M. on the 7th; 

 that it began at Charleston at eleven the same night, and 

 did not become formidaole at Savannah before ten in the 

 morning of the 81 h, consequently it did not begin at 

 Charleston untd eight hours and a half after it began at 

 the Frving-pan, nor at Savannah sooner th^n the nme- 

 teenth hour and a half subsequent to its commencement 

 at the same place. Hence, on comparing this storm with 

 the one before alluded to, it is evident that this, which hid 

 its rise to windward, was not near so rapid in its progress 

 as that one which took its origin to leeward. 



From all these facts and considerations there is reason to 

 believe, that this gale, consisting chiefly, as it advanced 

 toward the Continent, of currents from the north-east, cast, 

 and south-east, was the trade-wind diverted from its ordi- 

 nary course, and blowing with a force prodigiously aug.. 

 mented over a tract considerably to the northward of its 

 usual limits. The two columns of agitated atmosphere 

 moving obliquely toward each other, appear to have met 

 and expanded their combined forces upon that bend of the 

 coast which forms the front of North Florida, Georgia, and 

 South Carolina. At present I know too little of atmo- 

 spheric movements to detern)ine what was the particular 

 rarefying or expanding cause that, on this occasion, put 

 the windward air into such destructive commotion, made 

 it rush with such resistless impetuosity to leeward, and 

 more particularly determined it to quit the intra-tropical 

 regions, and exert its whole strength upon a part of the 

 Continent so far to the northward as that which lies be- 

 tween St. Augutine and Wilmington, betwixt the latitudes 

 of 29° and 34° north. 



of Massachusetts in particular; and in the latter, this snowstorm from the 

 iiorth-east lasted thrice twenty-four hours, while in Maryland it did not at 

 furthest continue more than half the time, and certainly with less by far 

 than half the violence.
