His Excellency the Governor came on shore, when the party, consisting of the Governor, Mr. Bland, and myself, with three soldiers of the 96th regiment, and the Governor's servant, started at 7.15 a.m., steering north-east, crossed Moresby's flat-topped range at 9.0, made the North Chapman at 10.0, followed the stream upward till 11.50, the general course north-east by north. One native man and two women came up, and then retired to the other side of the river, watching our proceedings. Having dined, we started again at 2.25 p.m., steering a general north course over an indifferent scrubby country till 4.40, when we halted for twenty minutes to examine the black shale-like soil which was seen on a former occasion, but on digging it proved to be only alluvial soil resting on sand; from this spot we steered north 330 degrees magnetic over high sandy hills covered with scrub; the country gradually improved, and at 7.0 we halted for the night in a small grassy gully trending north-west, obtaining water in a native well.
5th December.
Started at 6.40 a.m., continuing the same course as yesterday evening over a succession of grassy hills of granitic formation till 11.10, when we halted on the eastern branch of the Bowes River; several natives shortly came to the encampment, and having eaten some biscuit and pork which we offered to them, retired in the evening to the opposite side of the stream-bed, keeping a close watch on us from behind some large rocks; a strict watch was therefore maintained by us during the night.
6th December.
This morning the natives commenced by throwing stones at the men who went down for the water, but we did not see any method of resenting it, except by expressing our disapprobation in words, and at 5.35 a.m. we started on a north-north-west course, the natives followed for about a mile, and continued throwing stones at the party. The country passed over was generally grassy granite hills till 9.0, when we ascended the high tableland between the valley of the Bowes and Hutt rivers, which last we reached at 10.25, and halted during the heat of the day on a pool of brackish water; at 3.20 p.m., again started, and following the river downwards, in a general course 310 degrees magnetic, at 6.10 bivouacked at the spot where we had before halted on the 17th October; the water in the pools brackish, but by digging near a moist bank obtained abundance of fresh water.
THE GERALDINE LEAD MINE.
7th December.
Left our bivouac at 5.50 a.m., and steered north-east over high sandy downs, covered with coarse scrub; at 10.30 entered the valley of the Murchison River; at noon halted at our bivouac of the 24th September, obtained some brackish water by digging in the sand of the small stream-bed. Having dined, we resumed our journey at 2.30 p.m., and bivouacked about 5.0 on the left bank of the Murchison, 500 yards below the large lead vein, obtaining good water in the sandy bed of the river by digging a few inches, the pools being all salt. While the men were preparing the tents, etc., the Governor proceeded to examine the vein of lead, which we traced to a greater distance than on the former occasion of its discovery, the water having sunk two feet, exposing many portions of the vein which were before covered.
8th December.
Examined the lead vein, tracing it 320 yards in a direction north 30 degrees east magnetic, along the bed of the Murchison River, which was nearly dry; clearing the sand and loose stones from the surface, found it to vary from eight to twenty-four inches in width, the general average being twelve inches, the dip to the west-north-west at an angle of about 80 degrees from the horizon. Throughout the whole length the lead vein appeared to be one solid mass of galena; the northern end either terminates or alters its direction close to a vein of schistose rock, which intersects the adjacent rocks; to the south the lode was covered by several feet of sand, which prevented its being traced further, as we had not time to remove it; the whole of the vein which was traced was included within the banks of the river, and the greater portion was covered by shallow water. One specimen of galena showed traces of copper. The rock which prevails on each side of the vein is a hard compact gneiss, abounding with garnets, some of which are of good colour, but mostly full of flaws; the stratification of the gneiss is somewhat confused, but it generally dips at a high angle (sometimes nearly perpendicular) to the westward, the strike being north and south. The facilities which the position of the lode offers for mining are not very great, as it occupies the lowest part of the valley, and steam power would be requisite to free the mine from water, and at the same time, unless the small boat-harbour near the mouth of the Hutt River, or Gantheaume Bay (both within thirty miles), be found suitable for the purpose, Champion Bay, distant sixty-two miles in a direct line to the south, is the nearest port where the ore could be shipped. In the evening the Governor examined the spot where Mr. Walcott had discovered the small pieces of lead ore about two and a half miles below the lode, but as most of the pieces had been picked up on that occasion, we could only find a few fragments of it.
