On the 22nd the leader made another search in advance, and in thirty miles came to a fine supply of water, in a gully running through a well-grassed plain whereon there was abundance of good feed for the horses.  To the south of this spot there was a small salt lake, which he named Lake Augusta.  Another good spring in grassy country was also found.  On the 30th of June Forrest made a scouting excursion to the eastward, but experienced ill fortune; for having penetrated as far as possible into the spinifex country, his horses gave out.  By the aid of some scanty pools of rainwater trapped in some rocks, he succeeded in getting a short distance farther on foot, and in reaching a low range.  From its summit he obtained an extensive but depressing view, such as too often greeted the explorer at that time and in that part of Australia.  Far away to the north and east, the grey horizon was as level and as uniform as the placid sea; spinifex everywhere, unbroken by ranges or elevations within over thirty miles.

He was now worried and perplexed as to the direction of his future movements.  The main party were following up his tracks; but to plunge unthinkingly into such a desert as lay in front of them were sheer madness.  Fate relented, however, and after much toilsome search Forrest found a small supply of water, enough for a few days, where he gratefully awaited the approach of his companions.

During the short respite thus accorded them, a diligent search for water was made amongst the low ranges, the only alternative being a retreat of seventy miles.  A little more water was found to the south-east, and, as there was coarse rough grass around the well, it helped to prolong their rest and afforded more time for further search.  This time Alexander Forrest went ahead, and twenty-five miles further to the eastward found a spring, which was named after him, the Alexander Springs.

Another scouting excursion to the east was likewise fortunate, as far as water was concerned, but the feed for the horses was very poor indeed, and they were suffering greatly.  They were now within one hundred miles of Gosse’s furthest point west, but that hundred miles was one long line of desert perils.  Repeated efforts to traverse it only reduced the little remaining strength in the horses, leading to no discovery of water.  But at length a kindly shower filled some rock holes to the north-east of their camp, and after much exertion and hardship they reached the old camp that Giles had named Fort Mueller, and were able to congratulate themselves upon having been the first to bridge the central gap of desert that separated the two colonies.

As the course of Forrest’s party from Fort Mueller to the telegraph line was more or less the same as that pursued by Gosse, it is unnecessary to follow the journal to its end.  It is enough to state that on Sunday, the 27th of September, the telegraph line was reached at a point some distance to the north of the Peake station.  Thus safely concluded an expedition that makes a mark in our geographical history, although it was accompanied by no notable discovery.  Central Australia had now been crossed in the same zone that had turned back the explorers from the east, and the fact that Forrest got through, equipped with only the ordinary outfit of horses stamped him as a leader of unusual foresight and judgment.
