The charcoal, with its adhering chlorides, was conveyed to the smelting-house and the gold smelted into bars of extremely pure metal. Messrs. Newbery and Vautin claimed for their process decreased time for the operation with increased efficiency. At Mount Morgan, when I visited that celebrated mine, they were using what might be termed a composite adaptation process.
The chlorinated water was then drawn off containing the gold in solution which was deposited as a brown powder by the addition of sulphate of iron. Great improvements on this slow and imperfect method have been made of late years, among the earlier of which was that of Messrs. Newbery and Vautin.
On leaving the barrels the pulp ran into settling vats, somewhat on the Plattner plan, and the clear liquid having been drained off was passed through a charcoal filter, as adopted by Newbery and Vautin. The manager, Mr. Wesley Hall, stated that he estimated cost per ton was not more than 30s., and he expected shortly to reduce that when he began making his own sulphuric acid.
Sometimes I would find him staring at my Madonna, as if he said, 'What in the world are all those topsy-turvy children about? Then he'd sit in the middle of a brook, in a water-color sketch by Vautin, as if bathing his feet, or seem to be eating the cherry which one little duck politely offers another little duck, in Oscar Pletch's Summer Party.
