NEAR NEW HARMONY, INDIANA. 11 



Though I am inclined to believe in Professor Espy's idea of an ascensional column, 

 of its origin, whether derived from the condensation of vapor, as affirmed by Espy, 

 or from electrical action, as contended for by Dr. Hare, I do not offer an opinion. 

 I chiefly desire that the contribution I here present may be useful in the establish- 

 ment of correct opinions as to the mode of action in tornadoes, and to assist by 

 facts any who are seeking to penetrate those depths obscure, in which the origin of 

 meteorological phenomena are ])uried.
