When this journey was made it was immediately after one of those wonderful seasons that transform these parts of Central Australia from a treeless and grassless desert to a land where the swelling plains that stretch from bound to bound of the horizon are as vast fields of ripening corn in their yellow summertide.
Riding girth high through the lovely natural grass, from which the ripe seed scattered as they passed, or camping at night surrounded by it, the horses and camels improved in condition each day, and were never at a loss for water. Sometimes they found a sufficiency in a natural well or claypan; or again they struck for some creek towards the west or north, whose irregular curves were outlined on the plain by the gum-trees growing closely on its banks.
Nowhere did they experience great difficulty or serious obstacle on their northward way, though sometimes, as they crossed the rough ironstone ranges which crop up now and then on this great and ever rising table-land, there was little feed, and the sharp stones cut the feet of the animals as they trod with faltering footsteps down the precipitous gulleys, out of which the floods had for ages torn a path. As they followed the dry bed of such a path leading to rich flats, they would come upon quiet pools deeply shaded by gums and marsh mallow, that had every appearance of being permanent.
After they had been out ten days and had travelled over two hundred miles, Burke had formed so good an opinion of Wright that he made him third in charge, and sent him back to Menindie to replace Dr. Beckler--whose resignation was now accepted--in command of the portion of the expedition at that place. Wright took with him despatches to forward to Melbourne, and his instructions were to follow up the advance party with the heavy stores immediately.
Burke now pushed on to Cooper's Creek; and though the last part of their journey led them over many of those tracts of country peculiar to Australia where red sandy ridges rise and fall for many miles in rigid uniformity, and are clothed for the most part in the monotonous grey of salt and cotton-bush leafage, yet they saw before them what has since proved to be one of the finest grazing lands in the world.
