In the Western States of America, where water is measured out with mathematical accuracy and applied with clockwork regularity, agriculture has been raised almost to the rank of an exact science. The soil of Western Queensland is quite equal to that of the States in fertility, and similar methods should here produce similar results. When even the sterile Sahara is gradually disappearing before the irrigation works of French engineers, there is no need to despond regarding the future of the very driest parts of Queensland. In Egypt and Spain and in several of the American States, the water for irrigation is obtained from perennial streams drawing their supplies from distant snow-clad mountains. Kansas differs in this respect from other States. The description of the rivers of Western Kansas by an American humorist might have been penned with equal appositeness of the rivers of Western Queensland: "They are a mile wide, and an inch thick; they have a large circulation, but very little influence." Fortunately for Kansas, water is everywhere procurable by sinking shallow wells. In Dakota and Texas, thousands of millions of gallons are poured on to the land daily from thousands of artesian wells. Though lofty mountain chains are lacking, with summits high above the line of perpetual snow and giving birth to rivers rivalling Nile and Mississippi in volume, both of these latter sources of supply are available in Queensland. East and west of the Great Divide, abundance of water has been obtained from wells. Our western rivers may flow intermittently on the surface, but sub-artesian water is plentiful in many localities, and the great artesian basin, with its area of no less than 372,000 square miles, coincides generally with that part of the State which has a rainfall of 20 inches or less, a wise Providence having apparently created this huge subterranean reservoir to guard against excessive evaporation and to compensate for the light rains.
