which they first fell; owing, as I infer, to the more violent force 
exhibited at and immediately behind the center of the whirl, or 
at the point which may not inaptly be termed the heel of the 
vortex.* 
It is trne, however, as I have “admitted,” that vibe trees are 
found to have fallen one upon another, the top of the uppermost 
tree points in a direction more offtward than the one beneath; as 
is seen by the diagrams and schedules of Prof. Bache, and as may 
be inferred, perhaps, from the sketches given by Professors Olm- 
sted and Loomis:+ And it is equally true, that this fact no more 
favors the hypothesis of a directly inward motion, than that of a 
whirlwind; but, as an abstract deduction, is “reconcilable” with 
either. The proper generalization of this class of facts I have 
attempted to give in my paper on the New Brunswick tornado; 
which is ‘that the uppermost or last fallen of these trees points 
most [or more] nearly to the course pursued by the tornado ;’ i.e. 
more nearly than the underlying tree which first fell; divergence 
from the course of the tornado being still a marked feature of 
these overlying prostrations. 
L have never found a directly backward prostration on the line 
of the center, or axis, of the tornado. This, as well as the above 
mentioned facts, will be found sufficiently “irreconcilable” with 
a direct “afflux of the wind from all points of the compass,” ‘in @ 
central and non-whirling course,’ “ towards a common focal area.” 
_ In the same Journal, Dr. Hare says he “cannot understand 
how the opposite forces belonging respectively to the different 
sides of the whirlwind, can be made to bear successively upon 
one spot, so as to cause trees to fall in diametrically opposite di- 
rections.” Phil. Mag. (25].—Neither can I understand this, if 
each of these “opposite directions” be parallel to the course of the 
tornado, as is alleged by Dr. Hare, in the passage last noticed. 
Dr. Hare next tells us—* A fact, irreconcilable with a gen- 
eral whirling motion, has been recorded by Messrs. Espy and 
Bache. A frame building was so situated as to be protected by 
another edifice in one direction from the suction of the tornado, 
and yet was exposed to its influence as it advanced, and as it 
moved —— : ents two oe the four parts, on which the frame
