The tank,before it starts work, is filled with water or solution up to the•lolulion otitlet. and the climes pulp is delivered on the in-clined plane, where it spreads over the whole of the surface ina very thin layer. The pulp thus enter* the solution without the^lightest splash, and is liound to continue its downward mo\e-mcnt on the one side of the partition The quantity of pulp, mproportion to the mats of solution contained in the settler, is so. .MPAKATUS FOR SLIMES TKE.\ small that it becomes diluted to an extent which is prac-tically impossible in any other way. The fine particles ofslimes assert to great advantage their specific gravity and con-tinue in their downward movement after they have arrived atthe lower edge of the partition, accumulating in the cone ofthe vat, from the bottom of which they are discharged. Thesolution, once freed from the slimes it originally contained,having now less gravity, rises in the contrary direction to thecolumn of pulp on the other side of the partition and is dis-charged through an outlet provided for tiiis purpose near thetoj) of the tank. The experiments so far made have given the greatest satis-faction. The following tables showing comparative results,will prove interesting. In every case, the pulp taken has comefrom the slimes plant after the gold has l)een dissolved, asfar as the slimes in question have permitted, during a treat-m
