222 PHILOSOPHY OF STORMS. 



appears to have been generally outside the coast, till, reach- 

 ing Long Island, it crossed the same, and entered upon the 

 State of Connecticut. It seems also to have passed west- 

 ward of New Haven, and to have entered the valley of 

 Connecticut river near Middletown, and after partially fol- 

 lowing that valley for some distance, and crossing the State 

 of Massachusetts, the storm must have disappeared towards 

 the eastern coast, and its further progress does not appear 

 to have been reported. The general analogy or correspond- 

 ence of the forgoing facts to the known phenomena of whirl- 

 winds and tornadoes will, it is believed, be sufficiently evi- 

 dent, at least so far as the difference in the magnitude and 

 other circumstances of these rotative masses will permit of 

 the resemblance." 



Facts collected by Mr. Espy, taken from the newspapers of 



the time. 



159. Aurora, Sept. 10, 1821. Norfolk, Sept. 4^. Among 

 the rest of our misfortunes, we are grieved to state that our 

 town was visited on yesterday by a storm or tornado, &c. 

 The morning was dark and gloomy; at 6 o'clock rain be- 

 gan to fall in torrents. At 10 it abated a few minutes, and 

 then came again with increased violence, and the wind 

 commenced blowing a heavy gale from the N. E., and con- 

 tinued to increase to an alarming height:. From 111 to 12| 

 o'clock, the fury was such as to threaten a general demoli- 

 tion, &c. About 12, the wind shifted to N. W., and con- 

 tinued its fury until half an hour after, and the storm began 

 to subside. At 4 o'clock, the wind changed to S. W., and 

 the weather became calm. 



New York, Sept. 4^. From Saturday (the 1st) till 4 

 o'clock, we were visited with repeated showers, accom- 

 panied with thunder and lightning. The wind veered and 

 shifted to almost every point.
