7. Mr. Webster observed some of the phe. phenomena ? nomena of this change of weather, in its beginning, at New-Haven.
This place is 89 miles from New York, or 331 from Wathe ington. Here the weather was clear in the early part of the evening, but was overcast by nine. The stormy commotion of the atmolphere seems to have begun about twelve.-At
Boston it was rather more than an hour later. Mufsachusetts. 8.Mr.Blair,an officer who was on board one
of three ships from Salem, in Maffachusetts, that were lost on Cape Cod during the storm, related, after his escape, that the weather, on
the day of their sailing, Sunday, Feb. 27, was breeze. remarkably fine and favourable. At sunset
they were about four leagues from Cape Ann light house, with a light breeze from S. E.

11. The storm began still later at Hallo. Kennebeck, well on the Kennebeck River. This place is 683 miles from Walhington. There the
sun Tole clear on the morning of the 22d. The air became cloudy in about a quarter of an hour. The snow began about eleven, and the storm had become furious within two hours
Profeffor Waterhouse and Benjamin meteorologicVaughan, Esq. have particularly attended to al ? these curious meteorological facts.
12. At Poughkeepsie, 82 miles N. of NewYork, and fituated beyond the first range of Poughkeepsie. mountains, the storm began about 4 o'clock on the morning of the 22d. And at Albany, 165 miles north of New York, it did not be. gin until a little before day break on the morning of the 22d.

14. Accounts from Charleston (S. C.) state Charletin,
Ilands. milcs,- By the newspapers it appears to have
been felt in the Bahama Islands.
15. It will be found on caleulation, that
between Charleston and Cape-Ann, along the proceeded coast, this stormy movement proceeded to
windward at the rate of nearly one hundred miles an hour; for, as it began at Charleston, say at three o'clock, at new-York at eleven, & offCape-Ann at two the next morning, there is a difference of eight hours between Charleston and New York, and of three hours be. tween the latter city and Salem, making in the whole eleven hours.
16.Now, computing the distance from Carlela
ton to N. York at about 800 miles, & from N. difference. York to Cape inn more than 250, there will
be a fea cost of almost 1100 miles fpept over by this form in somewhat more than eleven hours. But this computation applies only to the fea-coast: for if we take any given point, as the city of New York for example, and in-
stead of N. E. reckon due N. it will be found progress? that the progress is considerably flower: for
it took all the time between eleven at night and day-break next morning to reach Albany, only 165 miles distant in that direction.
17. Now, these remarks explain some mete
orological facts, which though of common paradoxical? obfervation, have hitherto seemed apradoxical
q unaccountable: for mariners know, that to form a good judgment of wind and weather, they must keep a look-out for clouds and chan
ges of atmosphere to leeward. In New York, accompanies. the rain or snow which accompanies a N. E.
storm can be seen by labourers along the docks
and wharves, in the S. W. at Staten-Island, wharves. ten or eleven miles distant, for some time. bea
fore it begins in the city, so as frequently to break off work, and put away their tools.
18.And it is confirmed by long obfervation
among the farmers in that vicinity, that snow. Vicinity ? banks, as they term them, are to be ieen in the S. W. many hours before the atmosphere where the observers are, is clouded in the smallest degree, or any current of air percepti- perceptible ble. They remark, further, that a judgment can be formed of the weather by noting whether the gathered clouds lowering in the diftant horizon are visible to the northward or southward of the setting fun. If at sunset they are to the $. of the luni, they predict a north-east storm, with show; if to the N. à fleet. fouth-east norm, with fleet or rain.
