124 On the Gales and Hurricanes of the Western Atlantic. 
St. Martin’s and St. Thomas on the 18th; passed the north-east 
coast of Hayti on the 19th; Turks Island on the 20th; the Bahamas 
on the 2ist and 22d; was encountered off the coast of Florida and 
South Carolina on the 23d and 24th; off Cape Hatteras on the 25th ; 
off the Delaware on the 26th; off Nantucket on the 27th; and off 
Sable Island, and the Porpoise Bank, on the 28th. Its ascertained 
course and progress is nearly 3,000 miles,* in about eleven days; 
or at the average rate of about eleven miles an hour. The direction 
of its route before crossing the tropic, may be set down at N. 61° 
west, and in lat. 40° while moving eastward, at N. 58° E. 
k No. IV, represents the route of the hurricane which rav- 
aged the islands of Antigua, Nevis, and St. Kitt’s on the afternoon 
and night of August 12, 1835; St. Thomas, St. Croix, and Porto 
Rico on the 13th; Hayti and Turks Island on the 14th; the vicinity 
of Matanzas and Havana on the 15th; was encountered off the 
Tortugas in the gulf of Mexico on the 16th; in lat. 27° 21’, lom. 
94°, and other points on the 17th and 18th; and also at Metamora, 
on the coast of Mexico, (lat. 26° 04’) on the 18th, where it was most 
violent during the succeeding night.; This storm is remarkable, as 
moving more directly, and farther to the west, than is usual for storms 
which pass near the West India Islands, it having reached the shores 
of Mexico before commencing its sweep to the northward. Its 
course so far as known, is N. 73° west:—its progress more than 2,200 
miles in six days; which is nearly equal to 154 miles per hour. 
rack No. V, is that of the extensive hurricane of September, 
1804. It swept over the Windward Islands on the 3d of that month; 
the Virgin Islands and Porto-Rico on the 4th; Turks’ Island on the 
5th; the Bahamas and gulf of Florida on the 6th; the coast of 
oo the Carolinas on the 7th; the great bays of Chesapeake 
and Delaware, andthe contiguous portions of Virginia, Maryland, 
* All the di istances are expressed i in nautical miles 
+ Since writing the above it is ascertained that this storm also passed over Gal- 
veston bay, on the coast of Texas, where the hurricane blew with violence from 
to the southeast ; ye rationale of which may be made evident by drawing @ line 
through the northern side of the figure on the chart, parallel to the track of the 
storm. A little further attention to the figure will also illustrate the general char- 
acter of other northers, which are so common on the coast of Mexico during @ 
considerable portion of the year.
