Improved Sanitation Underground on the Rand. THE OBRIEN IMPROVED PATENT DRY EARTH CLOSET SECTION showing Hopper andGearing in position of rest,or immediately after footlever has been released. The OBRIEN Premier Drv Earth Closet Systemhas undoubtedly proved itself to be the PREMIERof all dry earth systems, and only requires to beknown on the mines to secure its general adoption. THE PRINCIPLE OF THE SYSTEM IS THESEPARATING OF THE LIQUID FROM THESOLID OR FCECAL MATTER, which is done bymechanism inside the pan. The Liquid is run intoa chamber under or near the pan, which chamberis partly filled with a chemical absorbent prepara-tion, and combining with the preparation therebyforms A PERFECTLY PURE, ODOURLESSSOLID, or by other means treated and allowed toflow away pure. The fcecal matt«r in the pan isautomatically covered v;ith a chemically preparedash, rendering it absolutely odourless, and can behoisted to the surface and carted away in opentarts during the daytime. The system itself is far superior to any otherdry earth system, and has been largely ADOPTEDBY THE SOUTH AF
