In the north-west the winds blowing from Indonesia in the winter are simply the north-east trades, which, coming from the northern hemisphere, change their direction with the cbange of zone. Between these two zones of the south-east and north- west monsoons the neutral region, shifting with the seasons from east to west and north to south, cor- responds in a general way with the York Peninsula. But in the south of Australia the prevailing westerly gales, which are often very strong and even tempes- tuous, find an unobstructed course from the Indian to the Pacific Ocean, and are consequently seldom de- flected from the normal direction. On the mainland itself the changes of the dominant currents, espe- cially in summer, are usually accomjDanied by sudden squalls known by the name of 'bursters.' The baro- meter falls rapidly, clouds of dust are stirred up, the storm gathers, peals of thunder echo from the welkin, and the rain comes down in torrents. In Melbourne these sudden gales from the interior are called 'bricklayers,' from the destructive whirlwinds of dust accompanying them. In the cultivated districts of the Australian coastlands no summer passes without several visitations of hot winds analogous in their effects to [Zl EZ] ^ 0 to « Inches. 6 to 10 Inches. 10 to 20 Inches 20 to 30 Inches. 40 to 60 Inches 60 Inches and upwards. 600 Miles.
