Through the midst of the city [Baghdad] flows a very large river, by which travellers may go to the Indian Sea. By this route merchants come and go with their merchandise. You should know that from Baghdad to the sea is a journey of fully eighteen days. Merchants travelling to India follow this river to a city called Kais, where they enter the Indian Sea. On the river between Baghdad and Kais there is a large city named Basra; and in groves all around Basra grow the best dates in the world. –“The Middle East,”
