detected. In every, .phase; the moon is the samejto t us, as a material 

 agent, except asfregards the power of reflected light ; and no one sup 

 poses that moonlight produces wet or dry. Why, then, should ^hat 

 point in the moon s course, when it begins to emerge from the sun s 

 rays, have any influence on our weather? Twice in each revolution* 

 when in conjunction with the sun at new, and in opposition to it at the 

 full, an atmospheric spring-tide may be supposed to exist, and to exert 

 some soi t of influence. But the existence of any such tide at all is 

 denied, and the absence of fluctuations of the barometric pressure favors 

 the negative of this proposition. Night-feeding birds and animals, 

 however, and oysters, grow fat or thin, according to the state of the moon 

 and tides. In Kentucky, horses are said to be subject to disease of the 

 eye, amounting to blindness, during the period of full moon, which is 

 not the case when the moon does not shine. Dark stables are the reme 

 dy ; and the philosophy of the disease is easily understood. 



In conclusion, every farmer is recommended to procure and use a good 

 Barometer. It will, at all times warn him of the approach of rain and 

 wind storms ; and after a little experience, he will find no difficulty in 

 deciding upon the weather for twelve or twenty-four hours in advance. 

 &quot;When he goes to bed at night, he can make a shrewd guess whether it 

 will rain or not in the morning; and during harvest he will be forewarned, 

 and can prepare for rain, and thus often save his hay and grain from 

 damage. At sea, a barometer is now of essential necessity. Mr. Red- 

 field, of New York, has lately pointed out the great service it will render 

 to those navigating our large lakes ; and to the farmer, it is quite as 

 useful As agriculturists become more familiar with the barometer, they 

 will cease to put faith in the weather-superstitions of the dark ages ; and 

 will find innumerable useful and interesting practical questions de 

 cided by it. There are two kinds in common use, the perpendicular or 

 circular Barometer, depending for its action upon Mercury (Quicksilver); 

 and the Aneroid Barometer a French invention depending on the ac 

 tion of gas in a thin metal case. The first is the most complete and 

 expensive, but the latter is quite sufficient for ordinary purposes, is not 

 easily damaged, and is much more compact. It requires, however, to 

 be occasionally compared with a standard mercury barometer.
