August 20, at Lowville, Pompey, Cazenovia, Utica. On the 

 evening of the 20th the Aurora Borealis presented an unusual 

 appearance. At half-past 9 the flashes of light, apparently 

 proceeding from a dense cloud in the horizon, shot up very 

 high in forms resembling pencils of rays. At 10, a broad arch, 

 resting in the horizon, in nearly the western point, rose be- 

 tween Arcturus and Ursa Major, and extending over the whole 

 heavens, a little north of the zenith, terminated about 20 de- 

 crees above the eastern horizon. Between this arch and the 

 polar star, stood a row of perpendicular columns of light, with 

 uniform bases, in a right line from Arcturus to the polar star. 

 There were sixteen pillars on the inside of the arch, and one 

 on the outside below Arcturus. They maintained their posi- 

 tion for nearly half an hour, and gradually ascending, in the 

 same regular order, grew fainter and disappeared. The flashes 

 in the horizon still continued very light, but not distinctly de- 

 fined : Utica.

Sept. 7, low but regularly arched, not above 20 degrees above 

 the horizon at 8 o'clock, but by the interposition of vapour 

 between the top of the arch and the horizon, forming a per- 

 fect segment of a circle at half past 8, two very bright lights, 

 extending from the top of the arch to 50 degrees : Lewiston- 

 Sept. 9, at Fredonia, Utica.
