king out such coarse pieces as could
be readily seen. To work the rocker a pan of dirt would be placed in the
square screen box, and then with one hand the miner would rock the
cradle while he poured water with the other from a dipper to wash the
earth. After he had poured on enough water and shaken the box
sufficiently to pass all the small stuff through he would stir over what
remained in the screen box, examining carefully for a nugget too large
to pass through the half inch holes. If the miner found that the dirt
did not pay he took his rocker on his back and went on in search of a
better claim.
Another way to work the dirt was to get a small head of water running in
a ditch, and then run the water and gravel through a series of boxes a
foot square and twelve feet long, using from one to ten boxes as
circumstances seemed to indicate. At the lower end of these boxes was
placed the "Long Tom" which was about two feet wide at the lower end,
and having sides six inches high at the same point. The side pieces
extend out about 3 feet longer than the wooden bottom, and are turned up
to a point, some like a sled runner, and this turned up part has a
bottom of sheet iron punched full of holes, the size of the sheet iron
being about 3 feet by 16 inches.
The miners shovel dirt into the upper end of the boxes slowly, and
regulate the water so that it dissolves the lumps and chunks very
thoroughly before it reaches the long tom where a man stands and stirs
the gravel over, and if nothing yellow is seen throws the washed gravel
away, and lets the rest go through the screen. Immediately below this
screen was placed what was called a "riffle box," 2 by 4 feet in size
with bars 4 inches high across the bottom and sides, and this box is set
at the proper angle. Now when the water comes through the screen it
falls perpendicularly in this box with force enough to keep the contents
continually in motion, and as the gold is much heavier than any other
mineral likely to be found in the dirt, it settles to the bottom, and
all the lighter stuff is carried away by the water. The gold would be
found behind the bars in the riffle box.
These methods of working were very crude, and we gradually became aware
that the finest dust was not saved, and many improvements were brought
into use. In my own mine the tailings that we let go down the mountain
side would lodge in large piles in different places, and after lying a
year, more gold could b
