of the United States and the West Indies. 115 
proceed, they become gradually extended in their dimensions, and 
weakened in their action, till they cease to command any peculiar — 
notice. One of the hurricanes of August 1830, has been traced in 
its daily progress, from near the Caribbee Islands, to the coast of 
Florida, and the Carolinas, and from thence to the banks of New- 
foundland ; a distance of more than three thousand miles, which was 
passed over by the storm in about six days. ‘The duration of the 
most violent portion of this gale, at the different points over which ‘it. 
passed, was about: twelve hours, but its entire duration was in many 
places, more than twice that period. Another hurricane which oc- 
cured in the same month, passed from near the Windward islands, 
on a more eastern but similar route, and has also been traced in its 
daily stages by means of the journals and reports of voyagers, near 
two thousand five hundred miles. It was in this storm, that the Rus- 
sian Corvette Kensington, Captain Ramsey, suffered so severely. 
The hurricane of August 1831, which desolated the island of Bar- 
badoés on the tenth of that month, the daily progress of which has 
also been ascertained, passed in nearly a direct course to the north- 
ern shores of the Gulf of Mexico and New Orleans, where it arrived 
on the 16th of the same month, having passed over a distance of 
twenty three hundred statute miles in six days after leaving Barba- 
does. Many cases of like character might be adduced. 
4, The duration of the storm at any place within its track, de- 
pends upon its extent and the rate of velocity at which it moves, as 
these circumstances are found to determine the time which is requi- 
red for the storm to pass over any given locality falling within its 
route. Storms of smaller extent or dimensions, are usually found 
to move from one place to another with greater rapidity than larger 
storms. 
5. The direction and strength of the wind exhibited by a storm, 
over the greater portion of its track, are found not to be in the direc- 
tion of ats progress. ‘The rate or velocity of this progress would in- 
deed be insufficient to produce any violent effect. 
-6. In the lower latitudes while drifting to the westward, the direc- 
tion of the wind at the commencement, or under the most advanced 
portion of these storms, is from a northern quarter, usually from 
north east to north west; and during the latter part of the gale, it 
blows from a southern quarter of the horizon, at all places whats the 
whole gale is experienced.
