On July 27th, they reached the bank of the Castlereagh, after a hard struggle through the bogs and swamps. The river was flooded, and must have risen almost directly after Mr. Evans crossed it on his homeward route. It was not until the 2nd of August that the waters fell sufficiently to allow them to cross. Still steering for the range, their course lay across shaking quagmires, or wading through miles of water; constantly having to unload and reload the unfortunate horses, who could scarcely get through the bog without their packs. Before reaching the range, the party camped at the small hill, previously ascended by Mr. Evans. Here they found the compass strangely affected: on placing it on a rock the card flew round with extreme velocity, and then suddenly settled at opposite points, the north point becoming the south. A short distance from the base of the hill the needle regained its proper position. This hill received the name of Loadstone Hill. Crossing Arbuthnot Range round the northern base of Mount Exmouth, the explorers, although still terribly harassed by the boggy state of the country, found themselves in splendid pastoral land. Hills, dales, and plains of the richest description lay before them, and from the elevations the view presented was of the most varied kind; this tract of country was called by Oxley Liverpool Plains. On Mount Tetley, and many of the hills about, the same variations of the compass were observed as had formerly been noticed on Loadstone Hill. Through this beautiful district the party now had a less arduous journey than before, and their horses were able to regain some of their lost strength. On the 2nd of September, they crossed a river which they named the Peel River, and here one of their number narrowly escaped drowning. Still pushing eastward, and continuing to travel through beautiful grazing country Oxley was suddenly stopped by a deep glen running across his track:-- "This tremendous ravine runs near north and south, its breadth at the bottom does not apparently exceed one hundred or two hundred feet, whilst the separation of the outer edges is from two to three miles. I am certain that in perpendicular depth it exceeds three thousand feet. The slopes from the edges were so steep and covered with loose stones that any attempt to descend even on foot was impracticable. From either side of this abyss, smaller ravines of similar character diverged, the distance between which seldom exceeded half-a-mile. Down them trickled small rills of water, derived from the range on which we were. We could not, however, discern which way the water in the main valley ran, as the bottom was concealed by a thicket of vines and creeping plants."
