On the 22nd September, he left his fourteenth depôt in the Cavenagh Range, and started on his return. His course home was by way of the Musgrave Ranges, where he found a greater extent of good pastoral country than he anticipated. He discovered and christened the Marryat and the Alberga, which last river they followed down almost to the telegraph line, and arrived at Charlotte Waters in December. Mr. Gosse's exploration did not add much fresh information to what was already known of the district, but it extended the area of explored country, and he was enabled to correctly lay down many of the points discovered by Mr. Giles. In March, 1874, Mr. Ross and his son, with a well-equipped party, consisting of another European and three Arabs, having with them sixteen camels and fourteen horses, started from the neighbourhood of the Peake Station, on the telegraph line, to endeavour to bridge the desert. He was, however, compelled to return, although he made another effort, after reducing the number of his party. Colonel Warburton having been the first to successfully make his way from the South Australian border to the settled part of Western Australia, Forrest was the next to aim and arrive at a successful issue. Forrest's trip was certainly the most commendable of the two, and by far the most important in its results. Warburton, with a troop of camels, reached the Oakover River naked and starving, with but two miserable animals left. Forrest, with nothing but ordinary pack-horses, crossed the middle of the continent, where the very heart of the terrible desert was supposed to exist, and took his men and most of his horses through in safety. Forrest, having with him his brother, Alexander Forrest, two white men, and two natives, left Yuin, then the furthest outside station on the Murchison, on the 14th of April. Their course at first was along the upper part of the Murchison River, which he describes as running through fine grassy flats, good loamy soil, with white gums in bed and on flats, the water in some of the pools being rather brackish. This description of country continued for many days, some of the river water being at times quite salt. On nearing the head of the Gascoyne River, the land was found to be fine, undulating downs, admirably adapted for sheep or cattle. On the 21st May, they ascended the watershed of the Murchison, and from the top had a fine view of their future travelling ground to the eastward. The country appeared level, with low ranges, but there was an absence of conspicuous hills--not a promising country for water, but looking as though good feed would be obtainable.
