 Longitude 90° W. Elevation above the Mississippi, about 200 feet. By J. 



L. PiCKARD.

 19th; Snow accompanied by vivid Lightning and heavy Thunder, April 10th ; Rain night of 

 June 1st and 3d, 3.65 inches ; First Snow, November 10th. 



A peculiar rustling noise was observed on the evening of the 27th of October, as of a large 

 flock of birds passing rapidly from N.W. to S.E. I am contident it could not have been 

 produced by birds, as it was time of full moon, perfectly clear, and no birds were to be seen, 

 though the noise produced was immediately over our heads.
