derived from the degradation of the hills by water. Associated with this clay and of more recent date are superficial deposits of pudding-stone and river gravels. The intrusive igneous rocks show mainly in the form of dykes, seaming the stratified rocks; consequently volcanic action took place subsequent to their deposition, but it was also antecedent to the more recent of the superficial deposits. It is in immediate connection with those plutonic dykes that we find the deposits of arsenic and cinnabar, occupying the fissures produced in the stratified rocks by volcanic upheavals, and we are led to the conclusion that these mineral lodes were deposited after the cessation of the upheaval.

      Gold occurs in the form of fine sand in the alluvial deposits, and in the gravel of the rivers over a great part of Sarawak; and also in pockets of the limestone, in which it has been allowed to fall by water. Nuggets are of extremely rare occurrence, but Sir Spencer St. John mentions having seen one of seven ounces taken from the auriferous clay at Krian near Bau. The gold dust is usually in a state of finest comminution. So far no gold reef has been come upon.

      In former days gold was extensively washed by Chinese at Bau and Paku in Upper Sarawak, which auriferous district commences at the confluence of the two branches of the Sarawak river, and extends back to their sources and the boundary of Dutch Borneo. As gold and antimony were known to abound here, the Chinese of Sambas and the lower Kapuas had made several endeavours to establish themselves in the district, but were much harassed by the Malays until the accession of the late Rajah Brooke, which made it possible for them to settle there and pursue in peace their business of gold mining. Then gold was washed extensively, and the fine reservoirs and "leats" which the Chinese constructed to sluice the alluvial soil remain to this day. They increased and became a thriving community, but they were not sufficiently looked after, and, falling under the machinations of socialistic Secret Societies, gradually got out of hand and broke into open rebellion in 1857, as shall be related in the sequel. It is sufficient to say here that this ended in dire ruin to themselves, and that the few who escaped were driven over the borders; but it also ruined the gold-mining industry, and, though some of the rebels returned and others came with them, the industry never fully recovered, and later on it received a further check by the introduction of pepper planting, which gave the Chinese a more profitable occupation, and gradually Upper Sarawak became covered with gardens of this description. Though gold mining under the Chinese practically died out, modern scientific and engineering skill has now placed it in a far higher position than it had ever previously attained, or could have attained under the primitive methods of the previous workers.

      In former years a large quantity of quicksilver was exported, but for some time this mineral product has ceased to appear as an item in the exports, the large deposit of cinnabar at Tegora having apparently been worked out. The existence of this mineral in other parts of the state is proved by traces found in several places, and the same may be said of antimony, of which there are indications of rich deposits; but the discovery of these minerals in paying quantities is a matter of chance. Antimony is still worked by the Borneo Company, Ltd., and a recent rise in the price has been an inducement to Chinese and Malay miners to increase the production, and the export of 1906 was more in quantity than it was in 1905, though small as compared with what it used to be.

      Black bituminous coal, which occurs in the Tertiary strata, has been found in different parts, and two collieries are owned and worked by the Government, at Semunjan in the Sadong district, and at Brooketon. Several hundred Chinese are employed as miners under European supervision, and large sums have been expended upon machinery, etc.

      Oil, a crude petroleum, has been discovered in two places; it is of good quality, and is an excellent lubricant.

      It is not impossible, or indeed improbable, that diamond deposits in Sarawak will be found and exploited. No systematic operations in search of these precious stones have been attempted, the dense jungle which covers the country being an obstacle. The only people who wash for diamonds are the Malays, and these carry on their work in a very desultory and imperfect manner.

      But agriculture and jungle produce have been, and will be, the main source of revenue to Sarawak, and prosperity to the country. We shall deal with these products, as well as with those that are mineral, more fully in a subsequent chapter.

      And we would add, to the superstitious native, to whom the jungles teem with ghosts and spirits.
