REMARKS
CHRISTCHURCH.
The two first days in August were cold and wet, half an inch of snow falling on the 2nd. From that day to the 18th, the weather was, as a rule, very fine and pleasant. Between three and four o'clock on the morning of the 15th, an earthquake wave struck the east coast of the Island, and a few minutes before ten o'clock a.m. of the 17th a sharp shock of earthquake was felt. On neither occasion was any warning given by the barometer that anything unusual was about to happen.
