I could see a long distance, but nothing met the eye but a dense scrub, as black and dismal as midnight." From this mount, accordingly, a straight course was steered to the sea-coast, during which every camping-place is marked on the map by the name of "desert." In the matter of provisions, they had for some time been reduced to one meal a day, and toward the close of the journey it was found that only two more remained to carry them a distance of 100 miles. In this dire extremity they were glad to feed on kangaroo mice, which, happily, were here to be found in great abundance. They are described as elegant little creatures, about four inches in length, of the shape of a kangaroo, with a tail terminating in a sort of brush. By means of this resource against starvation the explorers were enabled to cross the remaining stages of the desert, and so reached the habitations of civilized men. II. Mr. Stuart was the first explorer who reached the centre of Australia. The journey which led to this memorable achievement is worthy of detailed narration; but before entering upon this story it may be proper to say a few words on two preliminary essays in exploration, which, in some measure, opened the way to this much-desired result. About six months after his return from his first expedition, this indefatigable explorer started on a new journey to examine the extensive territory lying to the north of Lake Torrens and the east of Lake Eyre. This country proved, in some respects, a surprise to Australian discovery. It turned out to be unusually well watered, being furrowed at moderate intervals by a series of creeks, some of which were entitled to the name of rivers. But its most astonishing feature consisted in the myriads of springs, in groups ranging from two or three to more than a dozen in number. Some of these sent forth a stream of water which might have turned a mill-wheel, and continued to run a mile from the source. From this circumstance the whole territory has, not inaptly, been called the "spring" country. Another dominant feature was seen in the extraordinary abundance of quartz reefs, many of which bore plain indications of being auriferous, but, of course, could not be fairly tested by any appliances which were then to hand. Towards the close of the same year (1859) another journey was made to this part of Australia, when more accurate surveys were obtained, and the boundaries of a number of squatting runs laid down. In both of these expeditions important service was rendered to the better knowledge of this country, but they were especially valuable as furnishing Stuart with an advanced starting-point for his heroic project of crossing the continent from south to north. This arduous, but happily successful, enterprise will now be described in its main outlines.
