Remarkable Phenomena.—The Aurora Borealis appeared in N.N.E. at 8 o'clock on the evening of the 12th, near the horizon, and continued but a short time.

The atmosphere has been very thick with smoke during this month generally, occasioned by the burning of the prairies. This appearance has generally been near the horizon, but at some times, particularly in the latter part of the month, the whole of the sky has been obscured by smoke, bearing much resemblance in the morning, when there was little wind, to a thick fog.

6th—Fall of rain 3-16ths of an inch.
