J BR.ASS-YELLOW-NATIVE GOLD. J'5 A considerable quantity of gold has been of late years collected in North Carolina. It is there found in allu vial land. It would appear from the preceding statement, that most of the gold of commerce comes from America and Africa, and that by far the greatest proportion of this is collected from an alluvial land, which is frequently fer ruginous. The only considerable gold-mines in Europe, are those of Hungary, but the gold is principally the brass-yellow subspecies. - Second Subspecies. Brass-yellow Native Gold.
