In fact, this was the hypothesis suggested by M. Antoine d'Abbadie, who fancied that the Gugsa formed a southern pendant to the Blue Nile, which by an analogous bend described in the reverse direction, also joins the White Nile. But although no explorer has yet visited the Halal valleys and gorges through which the Uma, as it is also called in this part of its course, escapes
from the Ethiopian highlands, nevertheless the native reports are unanimous in asserting that after sweeping round the southern base of Mount Wosho, the Gugsa trends eastwards to the Galla country through a fissure in the border range.
