Susis is so fertile in grain, that barley and wheat produce, generally, one hundred, and sometimes two hundred fold. Hence the furrows are not ploughed close together, for the roots when crowded impede the sprouting of the plant.
The vine did not grow there before the Macedonians planted it, both there and at Babylon. They do not dig trenches, but thrust down into the ground iron-headed stakes, which when drawn out are immediately replaced by the plants.
Such is the character of the inland parts. The sea-coast is marshy and without harbours; hence Nearchus says, that he met with no native guides, when coasting with his fleet from India to Babylonia, for nowhere could his vessels put in, nor was he able to procure persons who could direct him by their knowledge and experience.
