washes the gravel from A to B. The coarse parts fall on either side 
of the double-inclined grate, while the finer parts fall through the 
grates on to the blankets in the box C; all but the black sand and 
the gold are discharged. The latter adheres to the blankets. The 
Dump Box is filled and emptied repeatedly for say ten hours, after 
which the blanket is washed in an ordinary tub, to the bottom of 
which the gold and black sand fall. The water is next poured off, 
and two or three charges of fresh water are poured into and out of 
the tub in order to further cleanse the gold and black sand. When 
these are sufliciently clean, they are removed from the tub to the 
gold pan. This is done by tipping the tub over the pan, and then by 
dashing water from the pan into the tub. The gold cannot be 
successfully removed from the tub in any other way. The pan is 
now held under water and shaken until the mass it contains is much 
reduced in bulk, by the separation of the lighter portions of the 
sand. Some quicksilver is poured in, together with clean water, and 
the pan is shaken until the quick silver has taken up all the gold. It 
is then again placed under water, and violently shaken to remove al] 
the black sand. The remaining contents are then poured into a 
wash-leather which has been previously wetted and stretched. The 
edges of the leather are secured in the right hand, when the centre 
of it assumes the shape of a pounce. The neck of this is wrung until 
all the free quicksilver is squeezed through the pores of the leather, 
and falls in fine beads into the pan placed for its reception. When 
opened the bag is found to contain a ball of amalgam of silver colour 
and of about the consistency of putty. This is moulded in the 
fingers to the required shape, and then placed upon an iron shovel.
