The apparatus is also adapted for treating sewage with air or chemicals, and for the settling and decantation of same. The process and apparatus is adapted for the treatment of alluvial and beach sands in a similar and direct manner without first pulverising the wash, but by first separating the large stones, pebbles, and the like with a revolving screen or similar means, and then treating the residue as for ordinary tailings. By means of the process and apparatus above described it will be seen that a comparatively thin body of material is exposed to the action of the cyanide or like solution, that such body of material is being continuously moved, and that the solution itself has a large surface exposed to the air, all these being very desirable features in the working particularly of the cyanide process, and that the treatment is a continuous one, the material passing through the apparatus at a rate which may be regulated by the manner in which the extraction is proceeding. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is,— 1. The herein-described continuous process for the treatment of pulp, slimes, tailings, and the like, consisting in moving a thin body of same in a cyanide or like solution having a large surface exposed to the air, and subsequently transferring such material and solution to settling-tanks, substantially as and for the purpose described. 2. The herein-described process for the continuous treatment of pulp, slimes, tailings, and the like with cyanide and similar solutions, consisting in subjecting a comparatively thin body or mass of same in the solution to the action of moving rakes or like apparatus, and subsequently allowing the mass of tailings or the like to separate from the solution in settling-tanks, substantially as and for the purpose described. 3. The herein-described process for the continuous treatment of tailings and the like with cyanide and similar solutions, consisting in subjecting a comparatively thin body of same to a raking or stirring action in water with or without quicksilver, lime, or other desired additions, and then treating such thin body in a series of baths, and in a continuously supplied cyanide or like solution, to the action of rakes or stirrers, and subsequently allowing the mass to separate from the solution in one or more settling-tanks, substantially as described. 4. The combination with a series of shallow tray-like baths, having suitably operated rakes or the like therein, of settling-tanks provided with means for the removal of the solid and liquid contents separately, substantially as and for the purposes described. 5. The combination with a series of settling-tanks having means for discharging the solid and liquid contents of conveyors adapted to transfer the solid contents of one or one series into the next tank or series, substantially as and for the purposes described. 6. The arrangement of apparatus substantially as and for the purpose described and illustrated in the accompanying drawings. Dated this 4th day of August, 1897. John Poole.

A Respirator for Use in Dry-crushing and similar Dusty Operations. I, Holroyd Fitz-William Way, of Hauraki, Thames, in the Provincial District of Auckland, miner, do hereby declare the nature of my invention for " A Respirator for Use in Dry-crushing and similar Dusty Operations," and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : — My respirator for use in dry-crushing and similar dusty operations is an apparatus consisting of a watertight vessel made of gutta-percha or metal with a capacity of about a quarter of a pint, and shaped outside like a watch, but the outside shape is immaterial. The watertight vessel is attached to the chest of the workman by a hook or pocket in the shirt, and is connected to the nose and mouth by a flexible tube of rubber with one end funnel-shaped, and lined with chenille or some fluffy material, to fit over the nose and mouth. The watertight vessel is about two-thirds full of water, and may be readily filled and emptied from time to time. On the accompanying drawing at Fig. lis an outside view of the watertight vessel. At letter A is an interior division shown by dotted lines, which separates the watertight vessel into two compartments, with the exception of. a small space at the bottom marked letter B. The water is shown by horizontal dotted lines. At letter Cis a funnel-shaped opening for admitting the dusty air. At letter D is a nozzle upon which is fitted the flexible tube, marked letter E. To fill the watertight vessel it is only necessary to pull it off from the flexible tube E and dip it into a bucket of water. To empty the watertight vessel when the water has become impure from dusty particles it is only necessary to pull it off from the flexible tube E and turn it upside down and shake the water out. The dusty air that is breathed through the watertight vessel is filtered by the water in manner similar to a Turkish hubble-bubble tobacco-pipe. The funnel-shaped end of the flexible tube is kept in position over the nose and mouth by a string or elastic passing round the head of the workman. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is : The watertight vessel with the interior division, the funnel-shaped opening, the nozzle, and the flexible tube, substantially as shown and described. Dated this 27th day of August, 1897. H. F. Way.

An Improved Combined Furnace and Precipitating Apparatus for recovering Gold from Charcoal or similar Substances. I, James Turnbull, of 72, King William Street, Fitzroy, in the Colony of Victoria, engineer, do hereby declare the nature of my invention for " An Improved Combined Furnace and Precipitating Apparatus for recovering Gold from Charcoal or similar Substances," and in what manner the
