sweep over the land, causing occasionally damage to stock and 
property. These cyclones are more frequent north of Broome than 
south of that place, where they mostly strike the coast and do aot 
extend their influence far inland. In the South, from the Murehison 
River to the Leeuwin, the wet season, on the other band, sets in 
after Easter, generally May, lasts through the winter and erds in 
October, with a few occasional showers during the summer months. 
During those winter months the weather is made up alternately of 
heavy showers and clear, sunny intervals. Ninety per cent. of the 
rain falls on an average in these six or seven months. In the South- 
Western corner the moisture-laden clouds which are carried on one 
side over the Sovthern Ocean, and the other over the Indian Ocean, 
impinge over the range of mountains which rise a few miles from 
the coast-line, and runs parallel with it for a distance of over 300 
miles, and there dissolve into heavy rain. Once blown over these 
ranges, farther to the eastward, these moisture-laden c'ouds meet 
with no obstruction to bring about their precipitation, an] thus ars 
earried away into the vast unsettled interior, where the farther from 
the coast the drier is the climate.

tralia at points located in the several divisions of the State :—
