For Foretelling the Weather, Throughout all the Lunations of Each Year, Forever
This table and the accompanying remarks are the result of many years' actual observation, the whole being constructed on a due con-sideration of the attraction of the Sun and Moon, in their several posi-tions respecting the Earth, and will, by simple inspection, show the observer what kind of weather will most probably follow the entrance of the Moon into any of its quarters, and that so near the truth as to be seldom or never found to fail:
If the New Moon, First Quarter, Full
Moon, or Last Quarter Happens In Summer In Winter
Between Midnight and 2 o'clock. Fair............Frost unless wind Southwest.
2 and 4 morning.... Cold and showers. Snow and stormy
4 and 6 " .... Rain............Rain.
6 and 8 " .... Wind and rain.. .Stormy.
8 and 10 " -----Changeable.....Cold rain if wind W, snow if E
10 and 12 " -----Frequent showersCold and high wind
12 and 2 afternoon. . .Very rainy......Snow or rain.
2 and 4 " .. .Changeable.....Fair and mild.
4 and 6 " ... Fair............Fair.
6 and 8 " .. .Fair if wind NW. Fair and frosty if wind N or NE
8 and 10 " .. .Rainy if S or SW.Rain or snow if South or SW.
10 and midnight......Fair............Fair and frosty.
Observations. - 1. The nearer the time of the Moon's change, first quarter, full and last quarter are to midnight, the fairer will be the weather during the next seven days.
The space for this calculation occupies from ten at night till two next morning.
3. The nearer to midday or noon the phases of the moon happen, the more foul or wet weather may be expected during the next seven days.
4. The space for this calculation occupies from ten in the forenoon to two in the afternoon. These observations refer principally to the Summer, though they affect Spring and Autumn nearly in the same ratio.
5. The Moon's change, first quarter, full and last quarter, happening during six of the afternoon hours, i. e., from four to ten, may be followed by fair weather; but this is mostly dependent on the wind, as is noted in the table.
C. Though the weather, from a variety of irregular causes, is more uncertain in the latter part of Autumn, the whole of Winter, and the beginning of Spring, yet in the main the above observations will apply to those periods also.
7. To prognosticate correctly, especially in those cases where the wind is concerned, the observer should be within sight of a good vane, where the four cardinal points of the heavens are correctly placed.
