NOTES ON GOLD. 39 
Having now shortly described the remarkable occurrence and 
purity of this Mount Morgan gold, a not less interesting, though 
dinary quartz-crushing and amalgamating 
machinery. The Capricornian says :—“The tailings which are 
being stored are said to contain as much gold as is saved, and as 
they will be subjected to treatment at a future date, the result will 
be highly advantageous to the owners.” Having the small quartz-

action of this acid upon manganese in the ore, whereby chlorine 
ments have been made by which the tailings will presently be 
treated at the mine by the chlorination process, whereby the gold
