To people who cannot comprehend such a region it may seem absurd that a man could not travel faster than that. All I can say is, there may be men who could do so, but most men in the position I was in would simply have died of hunger and thirst, for by the third or fourth day--I couldn't tell which--my horse meat was all gone. I had to remain in what scanty shade I could find during the day, and I could only travel by night. When I lay down in the shade in the morning I lost all consciousness, and when I recovered my senses I could not tell whether one day or two or three had passed. At one place I am sure I must have remained over forty-eight hours. At a certain place on the road--that is to say, on the horse tracks--at about fifteen miles from the Kegs--at twenty-five miles the Rawlinson could again be sighted--I saw that the tracks of the two loose horses we had turned back from there had left the main line of tracks, which ran east and west, and had turned about east-south-east, and the tracks of the Fair Maid of Perth, I was grieved to see, had gone on them also. I felt sure Gibson would soon find his error, and return to the main line. I was unable to investigate this any farther in my present position. I followed them about a mile, and then returned to the proper line, anxiously looking at every step to see if Gibson's horse tracks returned into them. They never did, nor did the loose horse tracks either. Generally speaking, whenever I saw a shady desert oak-tree there was an enormous bulldog ants' nest under it, and I was prevented from sitting in its shade. On what I thought was the 27th I almost gave up the thought of walking any farther, for the exertion in this dreadful region, where the triodia was almost as high as myself, and as thick as it could grow, was quite overpowering, and being starved, I felt quite light-headed. After sitting down, on every occasion when I tried to get up again, my head would swim round, and I would fall down oblivious for some time. Being in a chronic state of burning thirst, my general plight was dreadful in the extreme. A bare and level sandy waste would have been Paradise to walk over compared to this. My arms, legs, thighs, both before and behind, were so punctured with spines, it was agony only to exist; the slightest movement and in went more spines, where they broke off in the clothes and flesh, causing the whole of the body that was punctured to gather into minute pustules, which were continually growing and bursting. My clothes, especially inside my trousers, were a perfect mass of prickly points.
