Beyond the last escarpments the Cauca is joined by the Nechi, a considerableaffluent descending from the heart of the Central Cordillera, in nearly a straightline from south-west to north-east, thus forming, as it were, a chord to the arcdescribed by the mainstream itself. The Nechi is formed by two briinches, thesmaller of which keeps the name of the mainstream, although flowing in a lateral Fig. of the 1 : 1,600,OUO. ïf^^ --SA^TAMAR■r.^■,.

Both descend from the highlandsabruptly to the plains through a series of terraces, cascades, and rapids, like thoseof the Sogamoso. The Gruadalupe affluent of the Force plunges over a salto (fall)no less than 820 feet high. At the Nechi confluence the Cauca, here 2,000 feet wide, winds throuo-h alevel plain between low banks fringed with marshes.
