I was now resolved to make the most of the opportunity afforded me, and by travelling steadily onwards, to gain so much distance in advance of the two natives as to preclude the possibility of their again overtaking us until we had reached the water, if indeed we were ever destined to reach water again.  I knew that they would never travel more than a few miles before lying down, especially if carrying all the bread they had taken, the keg of water, guns, and other articles.  We had, however, seen none of these things with them, except the fire-arms.

Our road was over scrubby and stony undulations, with patches of dry grass here and there; in other parts, we passed over a very sandy soil of a red colour, and overrun by immense tufts of prickly grass (spinifex), many of which were three and four yards in diameter.  After pushing on for eighteen miles, I felt satisfied we had left the natives far behind, and finding a patch of grass for the horses, halted for the remainder of the night.  It was quite impossible, after all we had gone through, to think of watching the horses, and my only means of preventing from them straying, was to close the chains of their hobbles so tight, that they could not go far; having thus secured them, we lay down, and for a few hours enjoyed uninterrupted and refreshing sleep.

Moving on again on the 1st of May, as the sun was above the horizon, we passed through a continuation of the same kind of country, for sixteen miles, and then halted for a few hours during the heat of the day.  We had passed many recent traces of natives both yesterday and to-day, who appeared to be travelling to the westward.  After dividing a pot of tea between us, we again pushed on for twelve miles, completing a stage of twenty-eight miles, and halting, with a little dry grass for the horses.

It was impossible they could endure this much longer, they had already been five days without water, and I did not expect to meet with any for two days more, a period which I did not think they could survive.  As yet no very great change had taken place in the country; it was still scrubby and rocky, but the surface stone now consisted of a cream-coloured limestone of a fine compact character, and full of shells.  The cliffs, parallel with which we were travelling, were still of about the same height, appearance, and formation as before, whilst the inland country increased in elevation, forming scrubby ridges to the back, with a few open grassy patches here and there.  One circumstance in our route to-day cheered me greatly, and led me shortly to expect some important and decisive change in the character and formation of the country.  It was the appearance for the first time of the Banksia, a shrub which I had never before found to the westward of Spencer’s Gulf, but which I knew to abound in the vicinity of King George’s Sound, and that description of country generally.  Those only who have looked out with the eagerness and anxiety
