For the first few days after Burke and Wills set off they followed up the creek, and though the banks were rugged and stony, there was plenty of grass and soft bush near. They soon fell in with a large tribe of blacks, the first they had seen, who followed them for some time, and constantly tried to entice them to their camp to dance. When they refused to go the natives became very troublesome, until they threatened to shoot them.
They were fine-looking men, but easily frightened, and only carried as a means of defence a shield and a large kind of boomerang.
The channel of the Creek was often quite dry for a great distance; then a chain of magnificent water-holes followed, from whose shady pools pelicans, black swans, and many species of duck flew up in flocks at the approach of the travellers.
After a few days they reached what seemed to be the end of Cooper's Creek, and, steering a more north-easterly course, they journeyed for some time over great plains covered by dry grass-stalks or barren sandy ridges, on the steep sides of which grew scant tufts of porcupine grass; sometimes following the lines of a creek, or, again, travelling along the edge of a splendid lagoon that stretched its placid waters for miles over the monotonous landscape.
Even the stony desert they found far from bad travelling ground, and but little different from much of what they had already crossed.
Yet ever before them there, from the sunrise to its setting, the spectral illusive shapes of the mirage floated like restless spirit betwixt heaven and earth on the quivering heat-haze.
On January 7 they crossed the Tropic of Capricorn, and their way beyond it soon began to improve.
In the excitement of exploring fine country Burke rushed on with almost headlong feverishness, travelling in every available hour of the day, and often by night, even grudging the necessary time for food and rest. He walked with Wills in front, taking it in turn with him to steer by a pocket compass.
Before they left each camp its number was cut deeply into the bark of some prominent tree. Wills kept the little record there is of their journey, and as they went it was the duty of King or Gray to blaze a tree to mark their route.
They passed now over many miles of the richly grassed slopes of a beautiful open forest, intersected by frequent watercourses where the land trended gradually upward to the distant mountain-range. Sometimes they had to go out of their course in order to avoid the tangle of tropic jungle; but onward north by east they went, beneath the shade of heavy-fruited palms, their road again made difficult by the large and numerous anthills that give these northern latitudes so strange a solemnity and appearance of desolation.
