Read it through once

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.
