Remarks. x 
- The Barometer this month has again read above the arereee this time by 0120 
inch, the temperature being about the average. The month has been very dry in 
‘Sydney, and in the country the rain record is a very poor one. Many of the stations 
report less than an inch, some lees than half an inch. In the Northern coast districts 
good rains fell. A little rain fell in the North-western districts, and some along the + 
array ; but the want of rain has not been so much felt as it would ha abe ¥ 
: for the small quantity of wind w passed by. ee
