The wealth of Egypt was principally derived from taxes, foreign tribute, monopolies, commerce, mines, and above all from the productions of a fruitful soil. The wants of the poorer classes were easily satisfied; the abundance of grain, herbs and esculent plants, afforded an ample supply to the inhabitants of the valley of the Nile, at a trifling expense, and with little labor; and so much corn was produced in this fertile country, that after sufficing for the consumption of a very extensive population, it offered a great surplus for the foreign market; and afforded considerable profit to the government, being exported to other countries, or sold to the traders who visited Egypt for commercial purposes. The gold mines of the Bisharee desert were in those times very productive; and, though we have no positive notice of their first discovery, there is reason to believe they were worked at the earliest periods of the Egyptian monarchy. The total of the annual produce of the gold and silver mines (which Diodorus, on the authority of Hecatæus, says, was recorded in the tomb of Osymandyas at Thebes, apparently a king of the 19th dynasty) is stated to have been 3,200 myriads, or 32 millions of _minæ_--a weight of that country, called by the Egyptians _mn_ or _mna_, 60 of which were equal to one talent. The whole sum amounted to 665 millions of our money; but it was evidently exaggerated. The position of the silver mines is unknown; but the gold mines of Allaga, and other quartz "diggings," have been discovered, as well as those of copper, lead, iron and emeralds, all of which are in the desert near the Red Sea; and the sulphur, which abounds in the same districts, was not neglected by the ancient Egyptians. The abundance of gold and silver in Egypt and other ancient countries, and the sums reported to have been spent, accord well with the reputed productiveness of the mines in those days; and, as the subject has become one of peculiar interest, it may be well to inquire respecting the quantity and the use of the precious metals in ancient times. They were then mostly confined to the treasures of princes, and of some rich individuals; the proportion employed for commercial purposes was small, copper sufficing for most purchases in the home market; and nearly all the gold and silver money (as yet uncoined) was in the hands of the wealthy few. The manufacture of jewelry, and other ornamental objects took up a small portion of the great mass; but it required the wealth and privilege of royalty to indulge in a grand display of gold and silver vases, or similar objects of size and value.
