ABSTRACT OF THE DISCLOSURE A sonde has an at least approximately cylindrical drill- stem member, whereby the drill-stem member may be coupled with other drill-stem members into a drill string. A spiral winding is longitudinally about the drill-stem member for conveying drilled out earth up to a surface of the earth when the drill-stem member is rotated into the earth, whereby the drill stem member is an auger. At least one longitudinal surface portion of the drill- stem member is an electrical insulator that extends inwardly of the surface portion at least part of a radius of the drill-stem member. At least one measuring electrode is embedded in the electrical insulator. A connecting arrangement is in the drill- stem member for connecting the measuring electrode to electric operation and measuring equipment, whereby the auger is also an electrically logging sonde.
