JRemarks. 



The mean barometer is slightly below, and the mean temperature 1*5 above the 

 average of this month for the past 17 years. Rain has been frequent but very 

 light at Sydney ; and generally over the Colony the dry weather has continued, 

 doing great damage to pastoral and agricultural interests. At a few of the stations, 

 on the high lands and on the coast, there has been sufficient rain. Thunderstorms 

 have been frequent, and hail fell on 2nd, 5th, 16th, and 20th. Hot winds are 

 recorded on the 1st and 2nd at Narrabri, on the 8th at Moss Vale, and on the 12th 

 at Wentworth.
