168 ON TWO STORMS EXPERIENCED THROUGHOUT THE UNITED STATES, 
could be seen. By sunset, one of these patches of rain had assumed a very regular 
figure. It was about three hundred and sixty miles by two hundred and eighty, and lay 
directly over lake Erie, being fringed with snow upon its northern border... Near the 
middle of this ellipse, occurred a remarkable tornado, of which an account is given in the 
American Journal, Volume xliii., page 278. The clouds were much more broken than 
in the morning. By sunrise of the fifth, the whole was driven into the north-east corner 
of the United States. 
The following table shows the amount of rain during the entire continuance of the 
storm, for the western, middle, and eastern parts of the United States.

Thus it appears that, in the south-west, there was a considerable area over which the 
fall of rain must have averaged three inches; in the vicinity of Ohio, probably through- 
out the entire state, two inches fell; while throughout a considerable part of New Eng- 
land the fall averaged about one inch. It rained in the south-west about forty-two hours. 
At Hudson, from the beginning to the end of the rain was a little more than two days; 
it rained steadily about thirty-five hours. At Hanover, it rained about twenty-four hours, 
but from the beginning to the end of the rain was fifty-one hours. 
The following table contains all the stations where the direction of the clouds was 
recorded.
