ome fifteen by
eighteen feet on the ground, owned by the same person, fronting the
east, was driven by the wind to the opposite side of the street, and
now fronts nearly west; and what is most strange, is that the grass,
in the route the house must have passed over, stands straight as
usual, and gives no evidence that the building was pushed along on
the ground. A lady running from a house unroofed by the storm, took
an aerial flight over two fences, and finally caught against a tree,
which arrested her passage for a moment only, when, giving way, she
renewed her journey for a few rods, and was set down unhurt in
Mr. O. Reed's wheat field, where, clinging to the growing grain, she
remained till the gale went by."[11]

The weather at this place is briefly recorded in the accompanying
abstract from the journal, as well as in an extract from a note to
Professor Henry, of the Smithsonian Institution, from a friend of the
authors, who has long occupied a high official station in Illinois. But
such coincidences are of no value in deciding on the merits of such a
theory, it must be tried before the tribunal of the world, and applied
to phenomena in other countries with success, before its merits can be
fully appreciated. The accompanying record, therefore, is only given to
show how these vortices render themselves apparent, and what ought to be
observed, and also to exhibit the order of their recurrence and their
positions at a given time.

Institution, by Hon. John Dean Caton, on this subject._

"As a striking instance of the remarkable coincidences confirmatory
of these calculations, I will state, that on Friday, the first of
July last, this gentleman[12] stated that on the next day a storm
would pass north of us, being central a little south of Milwaukie,
and that he thought, from the state of the atmosphere, the storm
would be severe, and that its greatest violence would be felt on the
afternoon or night of the next day. At this time the weather was
fine, without any indications of a storm, so far as I could judge.
At noon on the following day he pointed out the indications of a
storm at the north and north-west, consisting of a dark, hazy belt
in that direction, extending up a few degrees above the horizon,
although so indistinct as to have escaped my observation. A
