The guides, through ignorance, deviated so far into the interior, that the sea was no longer in sight. The king, perceiving the danger, immediately set out in search of the coast; when he had discovered it, and by sinking wells had found water fit for drinking, he sent for the army: afterwards he continued his march for seven days near the shore, with a good supply of water. He then again returned into the interior. 7. There was a plant resembling the laurel, which if eaten by the beasts of burden caused them to die of epilepsy, accompanied with foaming at the mouth. A thorn also, the fruit of which, like gourds, strewed the ground, and was full of a juice; if drops of it fell into the eyes of any kind of animal it became completely blind. Many persons were suffocated by eating unripe dates. Danger also was to be apprehended from serpents; for on the sand-hills there grew a plant, underneath which they crept and hid themselves. The persons wounded by them died. The Oritæ, it was said, smeared the points of their arrows, which were of wood hardened in the fire, with deadly poisons. When Ptolemy was wounded and in danger of his life, a person appeared in a dream to Alexander, and showed him a root with leaves and branches, which he told him to bruise and place upon the wound. Alexander awoke from his dream, and remembering the vision, searched and found the root growing in abundance, of which both he and others made use; [CAS. 723] when the Barbarians perceived that the antidote for the poison was discovered, they surrendered to the king. It is probable, however, that some one acquainted with the plant informed the king of its virtues, and that the fabulous part of the story was invented for the purpose of flattery. Having arrived at the palace[420] of the Gedrosii on the sixtieth day after leaving the Ori,[421] and allowed his army a short period of rest, he set out for Carmania. 8. The position of the southern side of Ariana is thus situated, with reference to the sea-coast, the country of the Gedrosii and the Oritæ lying near and above it. A great part of Gedrosia extends into the interior until it touches upon the Drangæ, Arachoti, and Paropamisadæ, of whom Eratosthenes speaks in the following manner: we cannot give a better description. “Ariana,” he says, “is bounded on the east by the Indus, on the south by the Great Sea, on the north by the Paropamisus and the succeeding chain of mountains as far as the Caspian Gates, on the west by the same limits[422] by which the territory of the Parthians is separated from Media, and Carmania from Parætacene and Persia.
