“ From Hamirpur, the Jumna flows nearly due E., until it enters Allahabad district and passes Allahabad city, below which it falls into the Ganges in 25° 25′ N. and 81° 55′ E. In this last part of its course it receives the waters of the Betwa and the Ken. Where the Jumna and the Ganges unite is the prayag, or place of pilgrimage, where devout Hindus resort in thousands to wash and be sanctified. ”
