GOLD.
Beside those articles of trade afforded by the vegetable kingdom Sumatra produces many others, the chief of which is gold. This valuable metal is found mostly in the central parts of the island; none (or with few exceptions) being observed to the southward of Limun, a branch of Jambi River, nor to the northward of Nalabu, from which port Achin is principally supplied. Menangkabau has always been esteemed the richest seat of it; and this consideration probably induced the Dutch to establish their head factory at Padang, in the immediate neighbourhood of that kingdom. Colonies of Malays from thence have settled themselves in almost all the districts where gold is procured, and appear to be the only persons who dig for it in mines, or collect it in streams; the proper inhabitants or villagers confining their attention to the raising of provisions, with which they supply those who search for the metal. Such at least appears to be the case in Limun, Batang Asei, and Pakalang jambu, where a considerable gold trade is carried on.
It has been generally understood at the English settlements that earth taken up from the beds of rivers, or loosened from the adjacent banks, and washed by means of rivulets diverted towards the newly-opened ground, furnishes the greater proportion of the gold found in the island, and that the natives are not accustomed to venture upon any excavation that deserves the name of mining; but our possession, during the present war, of the settlements that belonged to the Dutch, has enabled us to form juster notions on the subject, and the following account, obtained from well-informed persons on the spot, will show the methods pursued in both processes, and the degree of enterprise and skill employed by the workmen.
In the districts situated inland of Padang, which is the principal mart for this article, little is collected otherwise than from mines (tambang) by people whose profession it is to work them, and who are known by the appellation of orang gulla. The metal brought down for sale is for the most part of two sorts, distinguished by the terms amas supayang and amas sungei-abu, from the names of places where they are respectively procured. The former is what we usually call rock-gold, consisting of pieces of quartz more or less intermixed with veins of gold, generally of fine quality, running through it in all directions, and forming beautiful masses, which, being admired by Europeans, are sometimes sold by weight as if the whole were solid metal. The mines yielding this sort are commonly situated at the foot of a mountain, and the shafts are driven horizontally to the extent of from eight to twenty fathoms. The gold to which sungei-abu gives name is on the contrary found in the state of smooth solid lumps, in shape like gravel, and of various sizes, the largest lump that I have seen weighing nine ounces fifteen grains, and one in my possession (for which I am indebted to Mr. Charles Holloway) weighing eight grains less than nine ounces. This sort is also termed amas lichin or smooth gold, and appears to owe that quality to its having been exposed, in some prior state of the soil or conformation of the earth, to the action of running water, and deprived of its sharp and rough edges by attrition. This form of gravel is the most common in which gold is discovered. Gold-dust or amas urei is collected either in the channels of brooks running over ground rich in the metal, in standing pools of water occasioned by heavy rains, or in a number of holes dug in a situation to which a small rapid stream can be directed.
