changed from clear to cloudy, and that snow began to fall; and at twelve, Mrs. Mitchill, who opened a window and looked out, obferved that the ground was already white with snow, the tempest was brewing, and,
properly speaking, was formed at two. bumphrey. 6. That night Mr. Humphrey Wood was
on board a floop bound f:om Newport ( R. I. ) to Newyork. The tempest drove the vessel alhore, before morning, on Mount-Misery Neck, upon Long-Island. They failed from Fither's Island, where they had been waiting for a wind, at 10 o'clock at night, with a
wind at E. S. E. and warm and pleasant bauled. weather. But by midnight it hauled E. N. E.
and blew a gale with snow. Filher's Island may be computed to be about 140 miles E. N. E. of New-York.
7. Mr. Webster observed some of the phe. phenomena? nomena of this change of weather, in its be
ginning, at New Haven. This place is 89 miles from New-York, or 331 from Walhington. Here the weather was clear in the carly part of the evening, but was overcast by nine. The stormy commotion of the atmol. phere seems to have begun about twelve. At
Boston it was rather more than an hour later, Mufsachusetts. 3•Mr.Blair,an officer who was on board one
of three ships from Salem, in Massachusetts, that were lost on Cape Cod during the storm, related, after his efcape, that the weather, on
the day of their failing, Sunday, Feb. 27, was ireeza. remarkably fine and favourable. At sunset
they were about four leagues from Cape Ann light house, with a light brecze from S. E.

and it snowed fo fast that the ships could difcern. hardly difcern each other. The hipwrecks
during this storm were numerous and dread. Frozen.

11. The storm began still later at Hallo Kennebeck, well on the Kennebeck River. This place is 683 miles from Washington. There the sun role 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 after. Professor Waterhouse and Benjamin meteorologico Vaughan, 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 begin until a little before day break on the morning of the 22d.
13. At Providence (R. I.) Dr. Wheaton observed the evening of the 21st. to be clear evening. and pleasante The watchmen informed him " the weather changed before 1 2 о'olock, and continued cloudy, with variable winds, until the violence of the storm began, which was at half past three of the morning of the 22d.” -Providence is 43. hiles from Washington,

Islands. miles,- 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, fay at three o'clock, at new-York at eleven, & offCape-Ann at two the next morning, there is a difference of eight hours between Charler: ton and New York, and of three hours between the latter city and Salem, making in the whole eleven hours.
16.Now, computing the distance from Carlera
ton to N. York at about 800 miles, & from N. difference. York to Cape-ann more than 250, there will
be a fea cost of almost 1100 miles fpept over by this storm 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? observation, have hitherto seemed apradoxical
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 diftant, for some time be
fore it begins in the city, so as frequently to break off work, and put awa
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 seen 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- perceptibla ble. They remark, further, that a judgment
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 S. of the sun, they predict a north-east storm, with snow, if to the N. a fleet. fouth-east norm, with fleet or rain.
Observations and reflections on storms, and some oth
er Phenomena of the atmosphere. In a Letter from Profesor Waterhouse, to Dr. Mitchill, dated Cambridge, (Massachusetts) March 20, 1802.
“ Dear Sir,
ing information of the precise time the late wide-Spreading storm commenced at this place, came to my hands evening before last. I hasten to gratify you as far as I am able.
2.“ Sunday, the 2iit. of February, the day chimnies, preceding the storm here, was remarkably calm and picasant. The smoke ascended from thermometer? the chimnies in a straight column. The thermometer at noon was 47. Neither hygrome- hygrometer? ter nor barometer indicated, at that period, any disposition of change in the atmosphere. barometer
3. As late as half palt tea at night, the sky was clear & star-light. At about two hours and a half after this, viz. one o'clock in the morning of the 22d the snow-storm began. My information comes from an intelligent intelligent? market-man who set out from his own house for Cambridge at midnight. Excepting for a
Wednesday. few hours on wednesday, 24th, we saw not the
fun for nine days. It was the longest if not feverest fuow-form lever knew.
4.“ I can readily conceive several good
purposes may be answered by this inquiry, I Halifax? have therefore written to Kennebec and to Hali
fax, and requested my correfpondent at the lalt place to extend his enquires to Newfound
land. I hope you will extend yours to PenjaJamaica. cola and even to Famaica. The severity of
the storm was from north-north-eatt; that is, Borth, two points to the east, being, you know, what the ancients termed aquilo.
5. These observations will probably
ftrengthen the opinion prevalent in this quarHemisphere? ter, that all our levere north east storms begin
first, in point of time, in the south-west. Franklin was first led to notice this, on being prevented by a stormy sky from observing an
eclipse of the moon at Philadelphia, when at elear.
Boston, 400 miles north-east of that city, the hemisphere was suficiently clear for that purpole.
6." It has always impreffed me with fome
thing bordering on wonder, that, during the centuries?
fix-and-twenty centuries wherein the memory and learning of mankind have been exercised, there has not been found one secretary of nature
fufficiently instincted to give us a complete afceni. history of the ascent of vapcurs from the ocean,
their fufpenfion in the air, tbe formation of clouds, descent. of fnow, and of the defcent of rain, with an entire
and connefied chain of causes.
