The manner of working the nninea is very 

 similar in both phices, but at Soongei Oojong 

 there is the great advantage ol ihe Chinese chain 

 putnp for tlie purpose of throwing off the water. 

 This machine is thus described by Mr. Tomb a. 

 " The apparattrs is simple* consisting of a com- 

 mon water whet. I, a circular wooden chain, about 

 forty feet in circumference, and a bug fiC|uare 

 hoKt or trough, through which it runs in ascend* 

 insr. The wheel and chain, 1 think, revolve on 

 a coromon axis, so that the motion of the former 

 necessarily puts the latter into action. The chain 

 consists of square wooden floats, a foot distant 

 from each other, and strung, as it were, upon a 

 continuous flexible axis, having a moveable joint 

 between each pair. As the float- boa rds of the 

 chain successively enter the lower part of the 

 box or trough, (immeri^ed in water), a portion of 

 water inconstantly forced up by each, and dis- 

 charged at the top. At one of the mines we 

 were much btrnclv with the simple, but efficient, 

 mode of its application— There were three dis- 

 tinct planes, or terraces, rising above each other. 

 On the middle one was the wheel; the lower was 

 tht? pit of the mine ; from the higher a stream of 

 water fell and turned the wheel, which, putting 

 the whole machine into motion, brought up ano- 

 ther stream from the pit; these two streams, from 

 above and l)elow, unitinj^r on the middle plane ^ 

 ran off in a sluice by which the ore was washed/'
