Tornado in N. E. part of Ohio, Feb. 4, 1842. 295 



flock of fifteen sheep belonging to Mr. Alderman and near his 

 honse, was overtaken by the tornado. Six were killed outright, 

 their legs were broken, and in many cases their entrails torn out ; 

 several of the living also escaped with broken legs. 



Having thus discovered the true ' experinientum crucis' for an- 

 alyzing the phenomena of tornadoes by observations of groups of 

 trees lying upon each other, I felt desirous of applying the same 

 test to the Stow hurricane, hoping it might remove the obscurity 

 which still rested upon that subject. I immediately set out to 

 re-examine the track. The traces of the hurricane were almost 

 entirely obliterated, with the exception of those left upon the 

 trees ; and upon the north side of the east and west road, these 

 being mostly fruit trees, had long since been righted. But in the 

 front on the south side, particularly in front of the house G, (see 

 this Journal, Vol. xxxiii, p. 369,) the trees remained almost with- 

 out exception undisturbed, and I had no difficulty in recognizing 

 individuals which I had before observed. The four trees partic- 

 ularly mentioned, p. 373, hne 16, are undisturbed, as the track 

 of the tornado is here as distinctly marked as it was the day after 

 its occurrence. The following groups of trees were measured, 

 the first being near the south border, the remainder towards the 

 centre.

Here we have a well marked rotation of the wind, and only 

 two anomalies, amounting to 9° and 13°. Mean of the bottom
