LABORS OF THE JOINT COMMITTEE. 103 



all the winter storms investigated before in our reports ; all 

 the winter storms, as well as the tornadoes or land spouts 

 in the summer, seem to travel from a point south of west, 

 while this long-continued storm was nearly stationary, 

 inclining, indeed, a little towards the south west, as it con- 

 tinued to rain in North Carolina and South Carolina, some 

 days after it ceased at Philadelphia. The Alleghany Moun- 

 tains seem to have been near the centre of the rain, extend- 

 ing from the western parts of New York to South Carolina. 

 The rain was copious as far west as Cincinnati and Lex- 

 ington, Ky., and as far east as the shores of the Atlantic, 

 hardly reaching Illinois, and extending but little way into 

 the Atlantic, and not prevailing much as far north east as 

 Massachusetts. 



Now, in Massachusetts, Connecticut, and New York, the 

 wind was constantly blowing from the north east during 

 the whole period of the storm. In Charleston, S. C., con- 

 stantly from the south and south east. In the interior 

 parts of the storm, the wind was variable ; the prevailing 

 winds, however, in the northern parts of Ohio being from 

 the north, in Illinois from the west, and in Alabama there 

 seems to have been nothing remarkable; no north east 

 storm occurred, but the direction of the wind is not given. 



It also appears by the log books of several masters of 

 vessels who left the Gulf of Mexico, about the beginning 

 of this storm, and arrived at Philadelphia about the end of 

 it, that they had the wind constantly from the south west 

 and south and south east fresh the whole way, gradually 

 passing the south and nearing the east as they approached 

 to Philadelphia. 



Thus it appears that on the north east and east, south 

 and south west, the wind was constant, for at least fourteen 

 days towards a great rain, and that on the other part of the 

 circle, even within the boundaries of the rain, the wind, 

 though variable, prevailed in a direction towards the centre 

 of the storm.
