A section of this auger (rf) shows the internal valve. The auger being introduced into the hole, and turned round by the workmen, the dirt or broken stones will pass tlirough the aperture at bottom (shown at e), and fill tlie cylinder, which is then drawn up, and dis- charged at the top of the auger, the valve prevent- ing its escape at bottom. 4489.
