Note 52 — Chapter VII · JOURNEY TO THE EASTERN SHORES OF THE LAKE TCHAD.

There is a prevailing report amongst the Shouaas that from a mountain, south-east of Waday, called Tama, issues a stream, which flows near Darfoor, and forms the Bahr el Abiad; and that this water is the lake Tchad, which is driven by the eddies and whirlpools of the centre of the lake into subterranean passages; and after a course of many miles under ground, its progress being arrested by rocks of granite, it rises between two hills, and pursues its way eastward.
