it does not even attempt to bear them, either fig or vine or olive, but for producing corn it is so good that it returns as much as two-hundred-fold for the average, and when it bears at its best it produces three-hundred-fold. The leaves of the wheat and barley there grow to be full four fingers broad; and from millet and sesame seed how large a tree grows, I know myself but shall not record, being well aware that even what has already been said relating to the crops produced has been enough to cause disbelief in those who have not visited the Babylonian land. They use no oil of olives, but only that which they make of sesame seed; and they have date-palms growing over all the plain, most of them fruit-bearing, of which they make both solid food and wine and honey; and to these they attend in the same manner as to fig-trees, and in particular they take the fruit of those palms which the Hellenes call male-palms, and tie them upon the date-bearing palms, so that their gallfly may enter into the date and ripen it and that the fruit of the palm may not fall off: for the male-palm produces gallflies in its fruit just as the wild-fig does.
