As the river below turned to the east of its general course, at 6.20 a.m. steered east-south-east and south-east till 9.30, when we again came on the river trending south. The country consisted of openly-timbered and grassy ironbark ridges, but not equally good with that passed during the last two days. The river at 10.0 turned to the south-east, along the foot of some steep rocky hills of porphyry resting on granite, and at 11.45 was joined by a dry creek twenty yards wide, coming from the south-west; our course was now east-south-east, passing with difficulty between the river and a steep granite hill, beyond which the country became more sandy, and rose to the south in long gentle slopes scantily grassed, and timbered with bloodwood, ironbark, Moreton-Bay ash, and poplar gum, with a few pandanus; an immense number of deep gullies intersected the ground, cutting deeply into the granite rock beneath the soil, and rendering it difficult to traverse. A fine range of openly-wooded and grassy hills rose about two to three miles from the left bank of the river, attaining an elevation of 500 to 800 feet above the valley; these hills are probably porphyritic; they are the Porter Range of Leichhardt. At 2.45 p.m. camped on the bank of the Burdekin River. THE SUTTOR RIVER. MOUNT MCCONNELL. 30th October. At 6.30 a.m. steered north 120 degrees east, but at 7.0 a.m. came on the river trending south, the country gradually became more rugged, and rocky hills closed in on both banks forming a deep gorge through which the river forced its way. By keeping at the back of some hills we avoided much of the rocky ground, crossing at noon a high ridge, from which the view extended to the junction of the Burdekin and Suttor Rivers, Mount McConnell bearing 159 degrees magnetic, and the west end of Porter Range 334 degrees magnetic. A long range seemed to extend south from Robey Range, and bound the valley of the Upper Burdekin, while a high range appeared to trend north-east from the eastern side of the Suttor Valley, and to turn the Burdekin to the north of east. Continuing our route nearly south-east over steep rocky ridges, we encamped in a fine grassy flat, a quarter of a mile from the Suttor River, at 1.50 p.m., Mount McConnell bearing north 172 degrees east magnetic. About 10.0 a.m. we heard some blacks calling in our rear, and soon after came in sight, but would not allow any of the party to approach them, till one of the horsemen cantering up quickly, some of the blacks climbed into trees, where, after making signs to them that it was desirable that they should pursue an opposite route to ours, we left them to descend at leisure. The country passed this day was of a broken character, with deep gullies and rocky hills near the river, but was generally well grassed and openly timbered with ironbark and Moreton-Bay ash. Granite rock forms the base of the hills, and was covered by masses of porphyry, forming hills with
