On the 22nd, the leader made another search ahead, and in thirty miles came to a fine supply of water in a gully running through a grassy plain, whereon there was abundant feed. Eight miles to the south there was a small salt lake, which was named Lake Augusta. Another good spring in grassy country was also found, and on the 30th June, Forrest made a further exploration ahead to the eastward. This time he was unfortunate, for he soon found himself fairly in the spinifex desert, and his horses knocked up. By the aid of scanty pools of rainwater in the rocks he managed to push on some distance, walking most of the way. He reached a range, and from the top had an extensive but most discouraging view. Far to the north and east the horizon was as level and uniform as the sea; spinifex everywhere; neither hills nor ranges could be seen for a distance of quite thirty miles. He was now perplexed as to his future movements. The main party were following up his tracks, and there seemed no prospect of getting through the country ahead of them. Fortunately they found a little water, enough to last a day or two, and there awaited the arrival of their companions. A search amongst the low ranges was then commenced, as the only other alternative was a retreat of seventy miles. To the great relief of every one A. Forrest and the black boy found water five miles to the south-east, with some coarse rough grass around it, that would serve them for a time. The younger Forrest then went ahead, and found some springs twenty-five miles distant, which were named the Alexander Springs, after the discoverer. Another excursion was attended with equally good results as regards water, although the country around was not at all desirable pasture land; and. this brought the explorers within one hundred miles of Gosse's furthest westerly point. To bridge this hundred miles proved a weary task. Repeated excursions only resulted in continued disappointment, and knocked up horses. At last a kindly shower of rain filled some rock holes to the north-cast of their camp, and after much labour and exertion the whole party found themselves at an old camp of Giles, which he had named Fort Mueller, and as they were also on Gosse's tracks the leader was able to congratulate himself upon the successful accomplishment of his mission. As the course of party, from here to the telegraph line, was more or less on the track pursued by Gosse, it is unnecessary to follow their fortunes any further; some privation had to be endured and one or two more of the horses gave in; but on Sunday, the 27th September, they arrived at the telegraph line some distance north of the Peake station, thus concluding one of the most valuable journeys on record.
