Above the Ichthyophagi is situated Gedrosia,¹ a country less exposed to the heat of the sun than India, but more so than the rest of Asia. As it is without fruits and water, except in summer, it is not much better than the country of the Ichthyophagi. But it produces aromatics, particularly nard and myrrh, in such quantity, that the army of Alexander used them on the march for tent coverings and beds; they thus breathed an air full of odours, and at the same time more salubrious.

The summer was purposely chosen for leaving India, for at that season it rains in Gedrosia, and the rivers and wells are filled, but in winter they fail. The rain falls in the higher parts to the north, and near the mountains: when the rivers swell, the plains near the sea are watered, and the wells are also filled. Alexander sent persons before him into the desert country to dig wells and to prepare stations for himself and his fleet.
