as it comes from the stamps, maybe allowed to flow mixed with water down the shoot 

 A. The supply of water should be taken from a head so as to be perfectly uniform i n 

 quantity. The water mixed with the ore flows in the direction of the arrows down 

 and then up the divisions B', B 2 , B S , B 4 , B 5 , each of which increasing in area, the 

 velocity of the ascending current diminishes in the same proportion. The particles 



of greatest specific gravity will be deposited in the bottom of B 1 . In the bottom of 

 B- will be found small particles of great specific gravity and large particles of small 

 specific gravity. The same relation will exist in B 3 , B 4 and B 6 , only the particles of 

 each will be smaller in succession. The plugs in the holes c c c being opened as is
