rd; the fog has followed on and
disappeared; there is a light trade air from the S. W.; the moon shines
out, and a few patches of stratus, broken up into fragments and melting
away, are following on in the trade: the storm is past.
Hark! to the tones of Boreas as he bursts forth from the N. W., and
rushing, whistling, howling, dashes on between the trade and the earth,
following the storm. Now the barometer rises rapidly, the thermometer
falls, and in an incredibly short time all is congealed, and cold and
wintery as before. The cold N. W. wind has again interposed between the
trade and the earth; the trade is elevated a mile or more above it and is
entirely free from its influence and from condensation; the deep blue of a
sky "as pure as the spirit that made it" is over us, and steady winter
reigns again.
It is obvious that there was nothing in the action of the sun upon our
snow-clad country, to induce the thaw or the storm. It began, continued,
approached, and passed off to the N. E. in the counter-trade. The S. E.
wind which existed every where within its influence: in the interior
States, Missouri, Illinois, Indiana, Ohio, Michigan, and in Canada, as
well as upon the Atlantic coast, commencing in the former earlier than
upon the last, was the result of its induction and attraction. Of the N.
W. wind that followed we shall speak hereafter. If any one doubts whether
this be a true sketch let him examine the investigation of a storm
published by Professor Loomis, or observe for himself hereafter. If,
however, the storm of Professor Loomis is referred to, it should be
remembered that his notes show the occurrence of a slight distinct snow
storm at the N. W. stations one day in advance of the principal storm. The
latter appears first as rain at Fort Towson, on the nineteenth, moving
north and curving to the east--its center passing near St. Louis, and
south of Quebec, and the whole storm enlarging as it advanced.
Take another instance. Since the thaw it has not been quite as cold as
before; but the rain-soaked snow is hard and solid, the ground, where the
snow was blown or worn off, icy and slippery--the thermometer falls during
the night to about 12 deg., and rises to about 30 deg.; the sun makes no
impression upon the snow; the firmament is of the deepest blue, the
borealis at night vivid. "O, for a storm of some kind, to mitigate the
still severe cold;" for the thaw has made us more sensitive, and storm
winds do
