hausted.” [23. 
Now I cannot but think, that readers who have no theory to 
support, will view the results of my survey in a very different 
light. Dr. Hare omits to mention, that the survey comprised the 
entire breadth of the visible track, at perhaps its broadest place ; 
that it was intended to include every tree prostrated within its 
limits; that it essentially agrees with the main features of the 
more partial surveys of Prof. Bache; that I have shown by clear 
inductions from all the prostrations in the survey that the whirl- 
ing motion was one general effect, comprising the entire width 
of the track; that the tornado must have arrived at this ground 
in nearly its most perfect action, having just left the surface of 
the Raritan river; that the axis of prostration was not found in 
the center of the track, but nearest its left margin; that the main 
rotation was wholly to the left or in one constant direction ; and, 
that the leading features of the prostration found in this survey, 
have also been observed as constantly oceurring, in the tracks of 
many other tornadoes.* 
I may add, that ina careful exploration of the track of this 
tornado for several miles, I found nothing to contravene the re- 
sults presented in my published survey ; the general features of 
the prostration being greatly analogous to those which I have 
given. 
Dr, Hare side it singular, that I should have declined noti- 
cing the “insuperable difficulties” of the hypothesis of ‘a cen- 
tral and non-whirling course in the wind of the tornado,’ to which 
Lhave alluded in bringing forward facts and inductions which 
Seem to contravene this hypothesis. He states, also, that “the 
advocates of the disputed hypothesis are not aware of any such 
difficulties,” and intimates the impropriety of the allusion “ with- 
out naming the facts and arguments” which justify it. [24.] 
- I considered it more proper, however, to rely solely on the sur- 
vey and inductions which I then presented ; as these appear sufii- 
cient to set aside, not only the hypothesis itself, but also some of 
the chief deductions from the phenomena of this tornado which
