After crossing the Murray the train passes through what is known as "the desert"--a stretch of country covered with mallee scrub (the mallee is a kind of small gum-tree); but nowadays they are finding out that this mallee scrub is not hopeless country at all. The scrub is beaten down by having great rollers drawn over it by horses; that in time kills it. Then the roots are dug up for firewood, and the land is sown with wheat. Quite good crops are now being got from the mallee when the rains are favourable, but in dry seasons the wheat scorches off, and the farmer's labour is wasted. It is proposed now to carry irrigation channels through this and similar country. When that is done there will be no more talk of desert in most parts of Australia. It will be conquered for the use of man just as the American alkali desert is being conquered. Leaving the mallee, the train comes in time to Ballarat, which used to be the great centre of the gold-mining industry. Round here gold was discovered in great lumps lying on the ground or just below the roots of the grass. People rushed from all parts of the world to pick up fortunes when this was heard of. The road from Melbourne was covered with waggons, with horsemen, with diggers on foot. Most of them knew nothing at all about digging, and also lacked the knowledge of how to get along comfortably under "camping-out" conditions, when every man has to be his own cook, his own washer-up, his own laundryman, as well as his own mining labourer. But the best of the men learned quickly how to look after themselves, to pitch a tent, to cook a meal, to drive a shaft, and to do without food for long spells when on the search for new goldfields. Thus they became resourceful and adventurous, and were of great value afterwards in the community. There is nowadays rather a tendency in civilized countries to bring children up too softly, to guard them too much against the little roughnesses of life. Such experiences as those of the Australian goldfields show how good it is for men to be taught how to look after themselves under primitive conditions. Life on the Australian goldfields, though wild, was not unruly. There was never any lynch law, never any "free shooting," as on the American goldfields. Public order was generally respected, though there were at first no police. The miners, however, kept up Vigilance Committees, the main purpose of which was to check thefts. Anyone proved guilty of theft, or even seriously suspected of pilfering, was simply ordered out of the camp.
