West Indian Hurricanes.—The West Indian hurricanes do not differ materially from other cyclonic storms in general principles, and they differ from the typhoons of the China Sea in name and place only. They are cyclonic storms of very great violence and, with the exception of tornadoes, they are the most destructive storms that reach any part of the United States. The wave that covered Galveston, the floods that many times have swept the Sunderbunds of India, and the storm that caused Isle Dernier to melt away were hurricanes of the cyclonic type—whirling up draughts toward which the surface wind blew from every direction.
