BEMABKS. The month commenced dull and dreary, with rain, but cleared and remained fine until the 20th, when the morn broke beautiful and oalm. Shortly after 8 a.m. a strong breezs came from the N.W. (from which quarter the wind came on the two previous days), rapidly increasing to a gale and at times almost with the force of a hurricane. The mean pressure of the wind for twenty-four hours on the 20th was 3 lbs. per square foot, but when the wind was strongest, at about 10 a.m., blowing a whole gale, the pressure would be about 625 lbs. per square foot. At 11 am. the wind moderated, but blowing occasionally with great force during the day and night. Considerable damage has been cansed by the storm. The remainder of the month has been fine, with occasional showers, there having been twenty-four fine days during the month. On ten mornings the thermometer on the grass registered below the freezing point. The rainfall has been about the average of the same month of tho past six years. The prevailing wind has been S.W. J.
