From The Gold Placers of the Vicinity of Dahlonega, Georgia, by William Phipps Blake, Charles Thomas Jackson, published 1859:
- It is the universal testimony of those who have worked in the placers of Georgia, that the gold is generally in larger lumps and particles, or is coarser than in the placers of the western parts of North Carolina, in Burke, McDowell and Rutherford counties. Mr. Blake also observes that the quality of the gold is excellent, rarely yielding less than 90 per cent., or 900 parts in 1,000, the difference being silver. The standard of gold of the United States consists of 900 parts of gold to 100 of alloy.
