CHRISTCHURCH.
The first day of the month was exceedingly fine, when the weather became unsettled until the 6th; a seasonable supply of rain, equal to about one inch in depth, falling on the nights of the 2nd and 3rd. The 5th day was cold and cloudy, with a sharp frost at night (23° F.), after which pleasant cool sunshiny weather prevailed until the 10th. That and the two following days were stormy, a very warm dry north-west wind blew continually during the daytime.

The wind changed to N.E. on the 13th, but returned to the N.W. on the 14th, which was again stormy and hot, with a cloudless sky.

On the afternoon of the 22nd there fell a few light showers of rain, but the following day was bright and clear. The 24th was dark, cloudy, and very
