'*s 
Tornado in N. E. part of Ohio, Feb. 4, 1842; 289 
tetisk. ‘They may perhaps be due to the increase of velocity of 
the wind in approaching the vortex, as before remarked. 
_ We next proceeded to the centre of Kirtland, where we under- 
took a similar investigation of the phenomena of the storm. Con- 
siderable rain fell here for about ten minutes—it was mingled 
with hail not much larger than a pea—broke some panes of glass 
- —not enough to whiten the ground. Had rained about five 
minutes before the most violent blast came on. The high wind 
did not last above ten minutes—the most violent blast only three 
or four seconds. ‘I'he air was filled with leaves and sticks, which 
made it quite dark, so that it was impossible to see but a short 
distance. It lightened three or four times before the blast—the 
thunder was quite loud. The best idea of the destruction will 
be gained by inspecting Fig. 6, Plate 1V. A, was a log-house 
blown down; B, log-house demolished; C, barn unroofed ; D, 
barn unroofed; E, barn and shop unroofed, house injured; F, 
north roofjof barn taken, south roof uninjured; G, house unin- 
jured; H, house unroofed, barn injured; I, north roof of one 
barn taken, entire roof of a second barn, house little injured ; 
J, house shattered, wing entirely destroyed, barn demolished ; 
K, house demolished; L, north roof of shop taken, shingles of 
barn all flew off at once like a flock of pigeons; M, house un- 
roofed, child two or three years old crushed by the falling of the 
chimney, the only death occasioned by the tornado; N, Presby- 
terian meeting-house; east side moved north twenty two feet, 
the west side, having the cupola, moved twelve feet—about one 
third of the north roof taken and otherwise badly shattered; O, 
north roof of house taken, two barns unroofed; P, house un- 
roofed; @, house unroofed; R, roof injured ; S, north roof taken, 
and chimney blown off. Where the ridge run east and west 
the north roof only was usually taken; where the ridge run 
north and south both were generally taken. ‘The fact here stated 
was found to hold generally true, that the leeward roof was taken 
in preference to the windward one. 
The following bearings of trees were taken in crossing a forest 
from T'to U. At first few trees were found lying upon each 
other. ‘The bearings were N. 65° W., moar -W.. N.. 12° W,, 
N.5° B,,N. 7° EB, N.8° B, N. 10° BE, NIE, N 15° E, 
N. 15° E., N. 20° E., N. 62° E., N. 78° E., N. 80° E. - The 
following groups of trees lying upon each other were observed,
