as those of the previous July. The maximuiii thernioineter in 

 shade was at or above 60° on twenty-three occasions, and above 

 70° on four occasions, the highest reading being 78° on the 

 18th. In July, 1906, the highest reading was 72° on the 5th, 

 and only twice was it above 70°. 



The continuous wet weather having chilled and soddened the 

 soil, vegetation w^as in a stagnant state until the diy, sunny 

 period came on, after which the change was remarkable, and a 

 fine healthy colour was assumed by annual crops. Haymaking 

 was in full swing by the 20th, and many farmers got their hay 

 crop secured in a satisfactoiy condition. Trees and shrubs com- 

 pleted their annual growth very fully, and garden plots of summer 

 plants, w^hich were in a languishing state, revived and grew 

 vigorously. 



August. — The month opened fine, but unfortunately the 

 weather broke down, and the conditions were by no means 

 pleasant, as these were very changeable, with heavy rains and 

 high winds at times, while towards the end of the month hail 

 showers were too frequent for the season. 



While the barometric readings do not sliow a wide range, they 

 indicate a somewhat unsteady line of atmospheric pressure. The, 

 pressure rose a point from the 1st to the 2nd, when it was at 

 29 '80 inches, then varying a point or two up and down daily 

 till the 10th, when the lowest reading for the month (29'30 

 inches) occurred. On the 13th it was at 29"80 inches, and for 

 a week several points lower, rising steadily after the I7th, till 

 on the 22nd it indicated 30"00 inches. During the last week it 

 varied between 29-55 on the 25th and 29-90 inches on the 30th, 

 with a downward tendency on the 31st. 



As in the previous August, which had an amount (5-28 inches) 

 above the average, the rainfall was again heavy for this month, 

 the amount registered being 4:"65 inches, with only 7 dry days. 



The heavy rainfall and absence of sunshine had again a marked 

 effect on the temperature, consequently the averages are low for 

 the month, the average maximum being 60°, and the average 

 minimum 49°, in both cases lower than those of the previous 

 August. In August, 1906, the maximum thermometer in shade 

 was five times above 70°, and only twice below 60° ; whereas in 

 the month under notice it was sixteen times below and but fifteen 

 times above 60°, while the highest reading was 67° on the 21st.
