Assam is noted for the abundance of gold found in many of its rivers; and as the manner of acquiring it by washing the sands may not be generally known, and is a subject of considerable importance, a description may not be uninteresting to the reader. In the first place, the gold washer, taught by experience, chooses a favourable site; a wooden trough, six feet long by one and a half broad and two inches and a half deep, is then placed on pegs driven into the sand: one end of the trough being raised to throw it into an inclined or sloping position. This effected, a shifting bamboo sieve, made to fit the trough, is placed upon it; two men with baskets then strew a plentiful coat of sand and gravel from the river on the sieve, through which the gold washer quickly washes the sand by pouring water on it, and shaking the sieve to hasten the descent of the water into the trough. By this means the heavier particles sink and the lighter are carried off by the stream, that continues to flow from the square or upper end of the trough to the circular end, from which it escapes by an aperture purposely bored. The coarse gravel on the sieve is frequently removed, and a fresh supply is continually heaped up, until the sand in the bottom of the trough containing the gold is about an inch thick. The sieve is then removed, and placed at one end of the trough, and a quantity of water being poured through the sieve, it falls on the sand like a shower of rain, till all the light particles are carried off by the stream flowing down the trough. By this process the heavier particles only remain, and these are gold dust and iron. The gold dust being now distinctly visible, is subjected to a further washing, and then dexterously floated on to leaves; after which it is transferred to a glazed earthen vessel, and again washed with the hand. The gold washer now daubs his hands with lime, and having applied some quicksilver and water, again washes the sand with his hands, which causes a scum to rise on the surface; this being cleared off, after repeated washings, the gold is found adhering to the quicksilver, when it is taken from shell to shell till every particle of sand is removed. The quicksilver and gold dust are then placed in a shell on a charcoal fire, and with the aid of a bamboo blow-pipe the ore is speedily melted; a little water being then applied, the gold is separated and forms a ball at the bottom of the shell. It is considered a good return if three persons at one trough can obtain four annas weight of gold (worth three rupees) in twelve days: giving the labourer one anna four pice per diem. At one time there was a numerous body of gold washers employed in collecting gold from many of the rivers in Upper and Central Assam; and the rivers were, in some instances, let by Government to persons wishing to enjoy the sole monopoly of bringing gold into the market. The profit on the gold dust must have been very considerable, seeing that it realized
