There can be no security in Central Australia until the water- supply is secure. Wbat Nature withholds with one hand she gives with the other: it is to the geologist that the .\ustralian turns for comfort in some of his sorest difficulties. In Australia geology is a first-line national service, and. A GcjR'.r. IX Tin; >[ACDONXEI, A(>1RA1,1A (By courtesy of the Hi^h Commissioner of Australia.) geology speaks concerning Central Australia with a voice restrained, but not pessimistic. The ancient rocks which form the ridges of Central Australia are frequently metalliferous: wide areas have been proved to contain good medium-grade ore : , in the vicinity of Arltunga, gold and mica ; at Hatches Creek, wolfram. But capital and then machinery, timber, water, and white labour are required to develop these deposits, and capital will not come until the enormous transport costs are reduced. Besides minerals, these ancient rocks gener- ally provide belts of fertile soil, with a good water- supply around their bases, and between the parallel ridges of the Macdonnells are numerous rich, if still dry and " unimproved," valleys. But b}' far the greater part of the area is covered with soft and relatively recent formations—sandstones, limestones, clays, and marls—sometim
