1860) and that it was probable that the story referred to a kind of marmot which to this very day lives in large communities on the sandy plateaus of Thibet. On the other hand more recent explorations in Thibet show us that there are still communities of gold-diggers, who in the rigour of the Himalayan winter clothe themselves in skins and furs, which are drawn up right over their ears in such a fashion that they present at first sight the appearance of large shaggy dogs18. Whichever explanation may be right, it may be inferred that from a very early time the region north of the Panjab afforded vast supplies of gold. The remark of Herodotus (III. 105) that it was from this source that the Indians obtained their wealth, and that there was not much gold mined in their own land, is probably correct. It is beyond all doubt that the gold of Thibet at all times found its way largely into what is now the Panjab. We need have little hesitation in believing that from a very remote epoch the rude tribes of the Himalaya must have been acquainted with the gold-dust, which lay in rich deposits in the various mountain streams.
To come towards the west, the great wealth of the Persian kings seems to have been derived from the basin of the Oxus, which was famous in antiquity for its golden sands. Thus in the Book of Marvels (a work ascribed to Aristotle and largely composed of extracts from his writings) it is stated that the river Oxus in Bactria carries down nuggets of gold many in number19. But the region from which Herodotus thought that in his time came the greatest supply of gold was the Oural-Altai region of Central Asia. The Greek Colonies on the northern coast of the Black Sea, the most important of which was Olbia at the mouth of the river Borysthenes, had a large and lucrative trade with the Scythians, who inhabited the wide plains of that bleak region. The Scythians were rich in gold which they obtained from the still remoter country of the Issedones, that people who, though righteous in all other respects, had the singular fashion of devouring their dead fathers. The Issedones again obtained by barter the gold from the Arimaspians, a race who had but
