Beyond this long, but comparatively narrow, sheet of water, a conspicuous mountain, named Olga, specially attracted the attention of Mr. Giles, who was anxious to reach it by rounding the lake. But this labour was prevented by an incident which, unhappily, caused the purpose of the expedition to collapse. Robinson had been seized with homesickness, and the infection reached Carmichael, who obstinately refused to proceed any further. Giles tried the effect of moral suasion, which was the only weapon available for a volunteer. He pleaded the large supply of provisions, the importance of the enterprise, and the ignominy of turning back. But it was to no purpose. Carmichael had made up his mind and would listen to no arguments. Giles was now compelled to direct his march back to the telegraph line, "a baffled and beaten man." During this inglorious retreat the course lay by the Peterman, the Palmer, and the Finke rivers, and by this route the original camp No. 1 was reached. Here is the conclusion of the whole matter in Mr. Giles's own words:--"My expedition was over. I had failed in my object (to penetrate to the sources of the Murchison River) certainly, but not through any fault of mine, as I think any impartial reader of my journal will admit.... We travelled to the eastward along the course of the River Finke (homeward), and passed a few miles to the south of Chambers's Pillar, which had been my starting-point. I had left it but twelve weeks and four days to the time I re-sighted it, and during that interval I had traversed and laid down about a thousand miles of country. My expedition thus early ends. Had I been fortunate enough to have fallen upon a good, or even fair, line of country, the distance I actually travelled would have taken me across the continent." II.
