252 Hurricane in New England, September, 1815. 



56. The following facts appear to me to be established by the 

 foregoing accounts. 



1st. The hurricane commenced in the West Indies, and moved 

 northward at the rate of twelve or fifteen miles an hour. 



2d. Its course from St. Barts was about W. N. W. to Turks 

 Island, and thence to Boston (nearly on the same meridian) it 

 was a curve convex to the west. (See account of Schr. Sally, 

 lat. 37°, Ion. 76°, for the most western point of the curve.) 



3d. Previous to the arrival of the hurricane in New England, 

 a N. E. storm had prevailed along the Atlantic coast for more 

 than twenty four hours. (See accounts, New York, New Lon- 

 don, Norwich, Worcester, and Boston.) 



4lh. For some hours previous to the hurricane, there was a 

 great and rapid condensation of vapor, producing a heavy fall of 

 rain in the line of the N. E. storm. (See accounts, Philadelphia, 

 New York, New London, Norwich, Worcester, Boston and Troy.) 



5th. The hurricane (that is, the violent blow) was mostly from 

 the S. E., blowing into and at right angles to the N. E. storm, at 

 its southern termination. 



6th. As the S. E. wind approached the line of the N. E. storm, 

 it was deflected into an E. wind. (See table, Salem, Boston, and 

 New London.)* 



7th. The general form of the hurricane in and about New 

 England was that of an eccentric ellipse, with its longest diame- 

 ter N. E. and S. W. ; wind blowing N. E. on the N. W. side ; 

 N. N. W. and W. N. W. at its south end ; S. E. on its S. E. side,t 

 curving into an E. wind at its junction with the N. E. current ; 

 wind blowing from S. at the easternmost part of the hurricane. 

 The whole body of the hurricane, in this form, moved to the 

 north nearly on the meridian. 



* May we not rather suppose that the more violent S. E. storm pursued its own 

 course of rotation in this direction by E. and N. E. without regard to the previous 

 N. E. wind which it had superseded? — Eds. 



t Did not this S. E. wind pertain more nearly to the centre of the path of the 

 hurricane ? For we find that the ship Prudence, twenty leagues from St. George's 

 Shoals, had a tremendous swell from S. W., which would appear to have been 

 produced on the S. E. margin of the gale. — Eds.
