place, it is toward the close of the storm. Occasionally, though very
rarely, it continues to storm after the wind has passed the point of N. N.
E., and until it gets N. W. I have known a few instances in the course of
thirty years, and but a few. They are exceptions--rare exceptions. When
the wind thus backs from the N. E. to the N. W. through the N., you may be
very certain that the body of the storm, or at least the point of greatest
intensity and greatest attraction, is at the time passing to the southward
of you. This is most commonly the course of the wind when the storm
extends far south and lasts several days, and does not extend north far,
or if so, with much intensity, beyond the point of observation. The
change of the wind is explained by the situation of the focus of intensity
and attraction, to the south of the observer, and its passage by on that
side.

Probably in locations further north and (as I think I have observed) south
of the lakes, it may be more frequent than upon the parallel of 44 deg. east
of the Alleghanies (which is as far north as I have observed), inasmuch as
the further north the locality, the more likely storms and other
disturbances in the counter-trade will be to pass to the southward of it.

Between the N. E. and S. E. the wind may blow from any point, before and
during storms, and in a clear day in the morning, as a light variable
breeze, or, after mid-day, toward approaching showers. I have known it
blow all day during a storm from due east; to change back and forth
between south-east and north-east, and to blow for hours from any
intermediate point--as different portions of the storm were of different
intensity, and exerted a more or less powerful inducing influence; and
doubtless this often takes place at sea. It depends upon the situation of
the focus of attraction of the storm, its shape relative to the particular
locality, and with reference to the atmosphere east of it, and peculiar
local magnetic action; or, as is sometimes the case in low latitudes, is
owing to the fact that the storm is made up of many imperfectly connected
showers, which have different force, and induce changeable and baffling
winds.

The inducing and attracting influence of the approaching storm is exerted
sooner, and with most force, upon the surface atmosphere, over bodies of
water like the ocean and the lakes. Thus, the wind will set from the
eastward toward an approaching storm out upon Long Island
