Q: [What is a Sluice Box?]
A: [Now what is a sluice box? A sluice box is a long, open-ended
trough containing many riffles. It rests on trestles. The trestles
provide for a uniform and gradual descent. Material is placed in the
head of the sluice box. Water flows continuously through the
material, washing it and breaking up any clumps. The lighter
material is then carried away, while the gold and the heavier
materials are trapped in the pockets formed by the riffles. Gold is
caught here!
Figuratively ... we must perform a dredging operation while we are
in this old world. We must do just as the sluice box does. The
sluice box saves the gold!]
