creeks, but the grass is scanty, and the rough surface of the sandstone and rocky ravines renders the country difficult to traverse. Timber is scarce, chiefly small-sized eucalypti; the cotton-tree was observed in a few of the valleys. 2nd October. Returning to the camp we attempted to follow one of the creeks down to the plain on the north-west side of the range, but found the ravine too steep and rocky for the horses to pass, and were compelled to retrace our steps and cross several steep and rocky hills, reaching the camp at 2.0 p.m., at which time the thermometer stood at 94 degrees in the shade and 114 degrees in the sun. 3rd October. Three of the horses had strayed, and this detained us till 11.0 a.m., when I started with the party, leaving Mr. H. Gregory and Bowman to look for the missing animals. Proceeding in a south-east direction to the crossing of the first creek, ascended the MacAdam Range, and steered east-south-east to the second creek; the course was then north-east and east to the head of the creek tributary to the Fitzmaurice River, and then encamped at 3.45 p.m. At the highest point on this day's route the aneroid stood at 29.40, and at the camp 29.55; thermometer, 88 degrees. The higher points of the range did not exceed 100 before the highest ridge crossed. By a meridian altitude of a Cygni, the latitude 14 degrees 33 minutes 26 seconds. 4th October. At 10.0 a.m. Messrs. H. Gregory and Bowen reached the camp with one of the missing horses, and, having obtained some provisions, returned to search for the other two horses. At noon started with the party, and followed down the creek in a south-south-east direction till 4 p.m., and encamped at the termination of the hilly country. One of the horses, Madman, showed symptoms of illness a short time before we started, and in crossing the creek half a mile above where we encamped he fell down and in less than three minutes died. This was a serious loss, as this animal was one of the most serviceable of our horses, having stood the voyage without losing his condition. The cause of death we were unable to ascertain; but the probability is that some poisonous plants existed at the place where we encamped last night. By a meridian altitude of a Cygni, the latitude of the camp was 14 degrees 39 minutes 26 seconds. Thermometer: Sunrise, 80 degrees; at 11 a.m., 93 degrees; wet bulb, 80 degrees. 5th October.
