On the 25tli the isobaric chart sho\v(^il the whole of Australia under very 

 weak barometric control, the isobar of 30 inches occupying the greatei- ]iait 

 of the mainland and forming a monsoonal dip over New South Wales ; l)ut 

 by the 27th a great change hafi taken place, for over the south-western 

 portion of the continent a " high " of .some energy had a])])eared, while the 

 rear of another was situated over Eastern Queensland and New South Wales. 

 Between these two anticyclones a long, nai'mw trough of low pi-essnre had 

 developed, exteiulin^ fiom Tasmania to Alice Springs, in Central Australia. 

 The.se conditions resulted in some good rainfalls over various divisions of the 

 State, the Central Tableland, Hunter and Manning, and j^ortions of the 

 South Coast faring best. The heaviest falls were as follows: — 271 points at 

 Lawson, 200 at Jerry's Plains, 199 at Picton, 170 at Sutton Forest, lo7 at 

 Bowra', 146 at Carcoar. 1 1 1 at Taralga, 106 at Camden, and 102 at Newcastle, 



At 9 a m. on tlie 2Sth very little change in the pressure distribution was 

 remarked, although the several systems had travelled slightly eastwai'd. An 

 incipient low pressure, however, covered the northern part of Australia. As 

 the result of the above-mentioned conditions, rain of a partial character — in 

 some cases associated with thunder — was received over parts of the Hunter, 

 Northern and Central Highlands, and Central-western Plains. During the 

 ensuing twenty four hours a curious development had occurred over Nortlicrn 

 and Eastern Australia. The low pressure had passed completely oft" the 

 mainland to the Tasman Sea, but the "high "" which was oft" our North Coast 

 experienced a slight retrogre.ssive moNcment, and a monsoonal tongue of low 

 pressure had formed ovei- the western poi'tion of New South Wales, with its 

 centre iti the noitlieni part of the continent. The centi'e of the anticyclone 

 to the south showed little or no easterly progress, but its advance isobars had 

 extended as far as Gabo Tsland and Tasmaida. 



That portion of the pressure disti-ibution whicdi was over our State caused 

 some very high temperatures in the Western Districts ; in fact, the highest 

 registered during the present summer. Brewarrina reported 119 degrees; 

 Bourke, 118; Carinda, 114 : and Mogil, liO degrees. 



Rainfall, associated with thunderstorms, was also reported from many 

 districts, the various subdivisions of the State being all more or less repre- 

 sented, with the exception of [the North Coast. Some heavy falls were
