 rock of granite or porphyry, which is penetrated by dark seams of metal, which have been worked out from above downwards, thus forming artificial caverns, pits, and shafts; and it may be inferred that the yield of ore was very abundant, and, from the simplicity of the manner of working, that it is of very great antiquity. This art of mining thus laid open, as Ritter says, furnishes the most important explanation of Job's remarkable description of mining operations. As to Egypt itself, it has but few places where iron-ore was obtained, and it was not very plentiful, as iron occurs much more rarely than bronze on the tombs, although Wilkinson has observed important copper mines almost as extensive as the copper country of Sinai: we only, however, possess more exact information concerning the gold mines on the borders of Upper Egypt. Agatharchides mentions them in his Periplus; and Diodorus (iii. 11ff.) gives a minute description of them, from which it is evident that mining in those days was much the same as it was with us about a hundred years ago: we recognise in it the day and night relays, the structure of shafts, the crushing and washing apparatus, and the smelting-place. There are the gold mines of Nubia, the name of which signifies the gold country, for NOYB is the old Egyptian name for gold. From the time of Sethoshi I, the father of Sesostris, we still possess the plan of a gold mine, which Birch (Upon a historical tablet of Rameses II of the XIX dynasty, relating to the gold mines of Aethiopia) has first of all correctly determined. Moreover, on monuments of all ages frequent mention is made of other metals (silver, iron, lead), as of precious stones, with which e.g., harps were ornamented; the diamond can also be
