On the Harrison (Ohio) Tornado. 163 
head of one of these valleys and just where the descent into it 
begins, stood a small frame house. The action of the win 
e house and the’ forest around, was extremely complex; and 
while sendin across the track with a compass, the whole effect 
seemed like a riddle designed to puzzle meteorologists. On this 
account the survey was minute and protracted. he path was 
divided into sections of three rods each. The plot gives but a 
cases a single arrow on the plot represents the mean of from three 
to ten bearings. The topography of the place is also represented 
as the complex action referred to, is believed to have been owin 
to the nature of the surface. The arrows give the directions of 
the currents which simultaneously or in succession swept over 
this ill-fated place 
he storm approached the house nearly from the west; and 
yet it was struck on the eastern side, by the current from the south- 
east. The proof of this is explicit. The whirling mass of vapor, 
attended with a thundering roar, was seen by Mr. Graham ap- 
proaching from the west: he shut the door,’a few moments of 
awful suspense followed: then a winded over the east door was 
driven in with a loud report; then the door followed; and the 
next instant the house was torn from its foundations and shivered 
to fragments 
The tenants bruised and bleeding, and with tattered garments, 
were found in different positions. 
The dotted arrows indicate the directions in which the frag- 
ments were carried. ‘They were strewed over the ground for 
about 30 rods west of the house, and lay between N. W. and W. 
6°S. Apa om of. the roof was carried W. 6° 8.; the chimney
