Messrs. Bedart and C.F. Gregory walked to the hill which lies three-quarters of a mile west of King's Table Hill. The rock of which it is formed appeared to belong to the coal formation, as thin seams of black shale were seen in the rocks of which the lower strata of the hill are composed; but the natives making their appearance, it was not considered prudent to remain geologizing among the cliffs. Returning towards the camp, the natives followed for some distance, and on descending a cliff the women commenced pelting the party with stones, apparently in revenge for the refusal of certain courteous invitations, which perhaps are the greatest marks of politeness which they think it possible to offer to strangers. CHAPMAN RIVER. 23rd October. Left our encampment at 8.5 a.m., and steered 150 degrees magnetic over granite hills producing wattles and good grass. At 9.40 crossed the south branch of the Bowes, after which the country was not so well grassed, except in the valleys. The lower hills were of granite; the higher red sandstone of tabular form. At 11.0 the country became more sandy and covered with short scrub, gradually rising to the south. At noon we attained the high tableland; crossed two scrubby valleys bounded by sandstone hills, in the first of which the black shale peculiar to the coal formation showed itself, with a slight dip to the south. At 1.50 p.m. crossed the Buller in a rocky channel with reedy pools, apparently of permanent character. The land improved and became grassy, and ascending the hills on the left bank, passed Peak Hill at 2.50: this is the highest part of the range between the Buller and Chapman. From this we steered south down a small grassy valley; the hills with granite bases and sandstone table summits, with excellent grass, and thinly wooded with acacia and a few York gums. At 3.15 bivouacked in a patch of excellent grass with water in small quantities. 24th October. A violent thunderstorm during the night was followed by a rainy and misty morning; the weather clearing up, we walked down to the Chapman River, which was running in a sandy channel with small shallow pools. The land on the bank of the stream was very indifferent and sandy for about a mile, when it rose into granite and sandstone hills, covered with excellent grass. EFFECT OF REFRACTION. GREENOUGH RIVER. 25th October.
