But where as one finds a sufficiently good climate and fertile land almost everywhere in the United States, it seems settled that inside of the Australian border-belt one finds many deserts and in spots a climate which nothing can stand except a few of the hardier kinds of rocks. In effect, Australia is as yet unoccupied. If you take a map of the United States and leave the Atlantic sea-board States in their places; also the fringe of Southern States from Florida west to the Mouth of the Mississippi; also a narrow, inhabited streak up the Mississippi half-way to its head waters; also a narrow, inhabited border along the Pacific coast: then take a brushful of paint and obliterate the whole remaining mighty stretch of country that lies between the Atlantic States and the Pacific-coast strip, your map will look like the latest map of Australia. This stupendous blank is hot, not to say torrid; a part of it is fertile, the rest is desert; it is not liberally watered; it has no towns. One has only to cross the mountains of New South Wales and descend into the westward-lying regions to find that he has left the choice climate behind him, and found a new one of a quite different character. In fact, he would not know by the thermometer that he was not in the blistering Plains of India. Captain Sturt, the great explorer, gives us a sample of the heat. "The wind, which had been blowing all the morning from the N.E., increased to a heavy gale, and I shall never forget its withering effect. I sought shelter behind a large gum-tree, but the blasts of heat were so terrific that I wondered the very grass did not take fire. This really was nothing ideal: everything both animate and inanimate gave way before it; the horses stood with their backs to the wind and their noses to the ground, without the muscular strength to raise their heads; the birds were mute, and the leaves of the trees under which we were sitting fell like a snow shower around us. At noon I took a thermometer graded to 127 deg., out of my box, and observed that the mercury was up to 125. Thinking that it had been unduly influenced, I put it in the fork of a tree close to me, sheltered alike from the wind and the sun. I went to examine it about an hour afterwards, when I found the mercury had risen to the-top of the instrument and had burst the bulb, a circumstance that I believe no traveler has ever before had to record. I cannot find language to convey to the reader's mind an idea of the intense and oppressive nature of the heat that prevailed."
