ABSTRACT
After passing these hills one arrives at the Tana or Sagana River, at which place there is a good llying bridge ferry. The Tana, which rises in Mount Kenya as the Sedana stream, is at this spot bringing water from the west of Kenya and the east of the Aberdares.. From this place it continues south-east till it has collected the waters of all the streams crossed on our way from Nairobi, and then turns north-east and picks up the water from the south of Kenya Mountain.
