When using self-feeders, fragments of steel tools are especially liable to get into the battery boxes or other crushing appliance where they sometimes cause great mischief. I believe the following plan would be a practicable remedy for this evil.
The stamps are so arranged as to be self-feeders, by means of huge wooden troughs with sloping bottoms, into which the ore is thrown in quantities sufficient to keep them constantly at work without requiring much or constant attendance. Small streams of water trickle over the ore to keep it slowly sliding down towards the jaws, where the stamps thunder up and down alternately.
