The labor of the top man is also avoided by a self-dumping- 
bucket observed at the Haile Gold Mine, South Carolina. 
This is an ordinary bucket fitted with guide wheels. The 
back wheels are caught by a latch at the dumping place 
and turns over when the rope is slacked off. Then the 
bucket is raised, the latch is withdrawn by the engineer 
and the bucket lowered.
