The remainder of the Kebrabasa path, on to Chicova, was close to the compressed and rocky river. Ranges of lofty tree-covered mountains, with deep narrow valleys, in which are dry watercourses, or flowing rivulets, stretch from the north-west, and are prolonged on the opposite side of the river in a south-easterly direction. Looking back, the mountain scenery in Kebrabasa was magnificent; conspicuous from their form and steep sides, are the two gigantic portals of the cataract; the vast forests still wore their many brilliant autumnal-coloured tints of green, yellow, red, purple, and brown, thrown into relief by the grey bark of the trunks in the background. Among these variegated trees were some conspicuous for their new livery of fresh light-green leaves, as though the winter of others was their spring. The bright sunshine in these mountain forests, and the ever-changing forms of the cloud shadows, gliding over portions of the surface, added fresh charms to scenes already surpassingly beautiful. From what we have seen of the Kebrabasa rocks and rapids, it appears too evident that they must always form a barrier to navigation at the ordinary low water of the river; but the rise of the water in this gorge being as much as eighty feet perpendicularly, it is probable that a steamer might be taken up at high flood, when all the rapids are smoothed over, to run on the Upper Zambesi. The most formidable cataract in it, Morumbwa, has only about twenty feet of fall, in a distance of thirty yards, and it must entirely disappear when the water stands eighty feet higher. Those of the Makololo who worked on board the ship were not sorry at the steamer being left below, as they had become heartily tired of cutting the wood that the insatiable furnace of the "Asthmatic" required. Mbia, who was a bit of a wag, laughingly exclaimed in broken English, "Oh, Kebrabasa good, very good; no let shippee up to Sekeletu, too muchee work, cuttee woodyee, cuttee woodyee: Kebrabasa good." It is currently reported, and commonly believed, that once upon a time a Portuguese named Jose Pedra,--by the natives called Nyamatimbira,--chief, or capitao mor, of Zumbo, a man of large enterprise and small humanity,--being anxious to ascertain if Kebrabasa could be navigated, made two slaves fast to a canoe, and launched it from Chicova into Kebrabasa, in order to see if it would come out at the other end. As neither slaves nor canoe ever appeared again, his Excellency concluded that Kebrabasa was unnavigable. A trader had a large canoe swept away by a sudden rise of the river, and it was found without damage below; but the most satisfactory information was that of old Sandia, who asserted that in flood all Kebrabasa became quite smooth, and he had often seen it so.
