"... Owing to the very minute proportion in which gold is often associated with rocks and mineral substances, it does not generally pay the cost of working; and the districts therefore known as auriferous or "gold-producing," in the the commercial sense of the term, are not so numerous ... Nearly all the gold of commerce has for a long time been obtained from , Brazil, Transylvania, Africa, the East Indian islands, and Carolina in the United States; the whole annual supply being estimated at about 80,000 pounds weight, and its value being about five millions . This however must be regarded as only an approximate value of the average of several years, as the supplies have for some time been increasing rapidly from the Russian mines."
