INDIAN SHIPPING
of the inclusion of a part of India as the twentieth satrapy of the Emperor Darius,[1] a fact which in the opinion of scholars accounts for the traces of Persian influence[2] on old Indian art, architecture, and administrative methods. Among Indian products Herodotus noted the wool which certain wild trees bear instead of fruit, "that in beauty and quality excels that of sheep,"[3] of which Indians make their clothing.
Herodotus also gives us some insight into the nature and extent of certain Indian mineral productions. Babylon obtained precious stones and dogs (probably Tibetan mastiffs) from India.[4] In the enumeration of the nations and tribes which paid tribute to the Persian monarch Darius, the Indians alone, we are told, paid in gold, all the others paying in silver. The amount of this gold was 360 Euboic talents, equivalent to £1,290,000. Herodotus also pointedly speaks of India as being "rich in gold,"[5] and he relates the famous and widespread fable of the gold-digging ants, which has been shown by Sir Henry Robinson and Dr. Schiern[6]
