Such an example may be reasonably received as supplying one satisfactory clue to the sources of the gold which we find to have been so abundant in early times; though we shall still, perhaps, consistently account for the introduction of some portion of it indirectly by foreign barter, and chiefly in the shape of the ring-money hereafter referred to. But when the fact is borne in remembrance that articles of silver are rarely, if ever, found in connexion with relics of the Bronze Period, it must be acknowledged as most consistent with the geological and mineralogical characteristics of auriferous and argentiferous deposits to look to native sources for the supply of gold. While silver is found only in large quantities by mining, gold has invariably been discovered in largest quantities in the superficial detritus, and accumulated in circumscribed areas. Whenever, therefore, we are enabled to trace the supply of gold to a foreign, as, for example, to a Phœnician source, we can hardly fail to find accompanying relics of silver; and accordingly, in the succeeding, or Iron Period, the gold becomes of rare occurrence, and the silver abundant. One other argument should not be altogether overlooked. The great purity of very many of the gold ornaments found in the tumuli is such as may perhaps add to the probability of its native origin. This well-known fact has frequently supplied an additional inducement to transfer to the crucible many of the rarest and most valuable relics of this period. Others found alloyed with silver are in no fixed or uniform proportions, but rather in accordance with the accidental mixtures likely to occur in the operations of the primitive miner and metallurgist. But this, though diminishing their bullion value, has not sufficed to save such national heirlooms from destruction. After reposing in the safe muniment chambers of their original owners, with but a foot of earth above them, while ancient races have become extinct and new colonists have risen to mighty nations above their forgotten graves, these treasures have only been restored to light to be immediately destroyed. The barbarity of such proceedings has hardly yet been fully exposed. It is the destruction of national records in the meanest spirit of cupidity, which no wealth could restore, and for which not even the poor excuse can be found that satisfied the fanatic Caliph Omar when he converted the treasures of the Alexandrian Library into fuel for the city baths.
