The foreign copper ores are merely introduced for the purpose of smelting, and 
•the purchasers of such ores are bound to export as much copper as is estimateds 
from assays made previous to sale, to be contained in them ; hence the quantity 
necessary to be exported depends on the accuracy of such assays. 
The amount of metal procured from foreign ores is sometimes nearly, or quite 
one-half the entire reduction, but for a few years past it has greatly diminished,
