There were only 9 dry days, and, though the weather was 

 showery, the amount of rain registered was only 2*37 inches, 

 which is less than what fell in July, 1905, when, with 12 dry 

 days, the amount was 2*81 inches. While there were fewer dry 

 days and a less amount of rainfall than what was experienced 

 in the previous July, the temperature was also< lower throughout. 

 In July, 1905, the maximum thermometer in shade was above 

 70° on 11 days, and even as high as 78° on two occasions, 

 while in the month under notice the thermometer was only 

 twice above 70°— viz., 72° on the 5th and 71° on the 26th— 

 and on 9 days it did not exceed 60°. Consequently the average 

 temperatures — maximum, 64°, and minimum, 50° — are in each 

 case 3° lower. 



While unpleasant for holiday-makers, the weather was, on the 

 whole, conducive to the healthy growth of vegetation, though 

 the showery conditions, with lower temperature, did not tend 

 towards early maturity. The harvesting of the hay crop began 

 during the first ten days, but thereafter operations were much 

 hindered by the frequency of rain showers. 



August. — During the greater part of the month there was a 

 continuance of the weather conditions which characterised July. 

 With the exception of four occasions, rain was registered every 

 day up to the 26th, and on several occasions thunderstorms were 

 experienced. The last five days were fine, bright, and warm. 



The changeable nature of the weather is well shown by the 

 irregular line of barometric readings. From 29*80 inches on 

 the 1st, the pressure sharply fell to 29 '30 on the 3rd. With an 

 equally sharp rise it was at 30*00 inches on the 6th. A steady 

 fall continued till the 13th, when for three days, during which 

 heavy rains fell, the pressure was at 29*30 inches. Then, with 

 a gradual rise, it reached 29*90 inches on the 19th. Afterwards, 

 with sharp changes, it touched 29*40 inches on the 25th, there- 

 after quickly rising to 30*15 inches on the 28th, which was the 

 highest point reached during the month, after which the tendency 

 was downwards. 



Owing to the frequency of heavy rains, the rainfall registered 

 was 5*28 inches — an amount considerably above the average. 

 There were only 8 dry days. In August, 1905, the rainfall 

 amounted to 3*61 inches, with 12 dry days.
