The New Student's Reference Work/Tsad

Tsad or Tchad (chäd), a lake in central Africa, about 150 miles long and 120 wide. Two large rivers flow into it, but it seems to have no outlet, though there are signs of an ancient river-bed, bordered by trees, in which the Arabs say water flowed for 100 miles during a flood in 1870. There are populous villages on the shores, and the many islands in the lake are densely peopled by pagan tribes, dark brown or black, with regular features, wearing cotton-garments and cultivating cotton and corn.
