12. I passed by mountains containing metallic earths of wonderful varieties, and by trees with branches broken by elephants, by lakes of crystal waters and lotus-lakes frequented by the gods,—lakes of imposing beauty where bees hover about disturbed by birds of wonderful notes.

13—14. I came in sight of a great forest impassably dense with rushes, bamboos and reeds, Kuśa and bamboos of the Keechaka variety, fierce and formidable, the abode of venomous serpents, owls and jackals.
