The mountain barrier between coast and tableland, though rarely exceeding 4,000 ft. in height, is still sufficiently lofty to cause the clouds of the Pacific to deposit most of their moisture on the Eastern slopes. The precipitation in this coastal belt ranges from a yearly average of 135 in. at Geraldton (at the foot of the Bellenden-Ker Mountains, in the North) to 40 in. between the Tropic of Capricorn and Brisbane, with a heavier fall wherever the mountains are in close proximity to the ocean. On the Western side of the Great Divide the rainfall decreases from 40 in. to about 30 in. at the Western limit of the tableland, and, gradually diminishing with increasing distance from the seaboard, averages only about 10 in. in the extreme South-west. Temperature, rainfall, and soil necessary for the successful cultivation of almost every known crop are to be found in Queensland. Pastoral pursuits and mining have been the principal wealth-producers in the past; but steadily agriculture is coming to the front, and, long before the present generation has passed away, will occupy first place among the primary industries. That it has not done so already is due partly to the comparative youth of the country and its small population, and partly to its rich natural pastures and vast mineral resources. For many years the fascination of a pastoral life and the search for gold, with the hope of winning fortunes in those avocations, proved more attractive than the regular, uneventful life of the farmer, with its prospect of a competence; but the old-time glamour of grazing and mining is passing away, and the independence of the farmer is now preferred to the lot of station hand or working miner. On the inestimable value of a rural population to the permanent well-being of a nation Mr. Roosevelt, the late President of the United States, lays stress in these pregnant words:-- "I warn my countrymen that the great recent progress made in city life is not a full measure of our civilisation; for our civilisation rests at bottom on the wholesomeness, the attractiveness, and the completeness, as well as the prosperity, of life in the country. The men and women on the farms stand for what is fundamentally best and most needed in our national life. Upon the development of country life rests ultimately our ability, by methods of farming requiring the highest intelligence, to continue to feed and clothe the hungry nations; to supply the city with fresh blood, clean bodies, and clear brains that can endure the terrific strain of modern life; we need the development of men in the open country, who will be in the future, as in the past, the stay and strength of the nation in time of war, and its guiding and controlling spirit in time of peace."
