Numerous kangaroos were seen bounding over the rocky slopes to the grassy glens below.  A stunted silver-leaved Ironbark covered the hills.

April 10.—­The night was very cold, particularly towards morning, and the dew heavy; the morning was calm; a breeze from the south-east set in at nine o’clock a.m.; cumuli formed about eleven o’clock, and became very heavy during the afternoon.

The country over which we travelled about eight miles N. by W., was one of the finest we had seen.  It was very open, with some plains, slightly undulating or rising into ridges, beautifully grassed and with sound ground.  We crossed the river I had seen the preceding day from the hill, and found it running.  Two large creeks, one from the right and the other from the left, also joined the Burdekin.  I observed Pegmatite of a white colour, and hornblende Porphyry and Diorite.  A shrubby Clerodendron and an arborescent Bursaria, covered with white blossoms, adorned the forest.  The latitude was 20 degrees 0 minutes 36 seconds.

April 11.—­We continued our journey up the river, in a W.N.W. direction, for about ten miles.  The first part of our journey lay through a most beautiful country.  The hollows along the river were covered with a dense sward of various grasses, and the forest was open as far as the eye could reach.  Farther on, however, we occasionally met with patches of Vitex scrub, and crossed some stony ridges.  A small river joined from the north-east, at about a mile and a half from the last camp, and also two large creeks from the south-west.  I ascended the hills opposite our camp, and looked over an immense and apparently flat country, out of which small peaks and short ranges rose.  The hills on which I stood were composed of Pegmatite, with patches of white Mica in large leaflets.  During the journey we found granite changing into gneiss, diorite, and quartz rock.

On the rocky crest of the hill, I gathered the pretty red and black seeds of a leguminous climbing shrub (Abrus precatorius).  Phonolithic or basaltic pebbles made me suppose that we were near to a change of country.  Our latitude was 19 degrees 58 minutes 11 seconds.

April 12.—­We had scarcely travelled a mile and a half, when we had to cross a large creek, which increased in size higher up.  Box-tree flats and open Vitex scrub extended along its banks, and the latter, according to Mr. Roper’s account, changed into dense Bricklow scrub.  At the junction of the creek and the river, we came on a dyke of basalt, the flat summit of which was so rough that we were compelled to travel along the flats of the creek, which for a long distance ran parallel to the Burdekin.  The soil on the basalt was so shallow that it sustained only a scanty vegetation of grass and some few scattered narrow-leaved Ironbark trees.  We crossed this dyke, however, and at about three miles descended from it into a fine narrow-leaved Ironbark flat, extending along the river, in which another large creek from
