The distance from Ngomano, a spot thirty miles further up, to the Arab crossing-places of Lake Nyassa Tsenga or Kotakota was said to be twelve days. The way we had discovered to Lake Nyassa by Murchison's Cataracts had so much less land carriage, that we considered it best to take our steamer thither, by the route in which we were well known, instead of working where we were strangers; and accordingly we made up our minds to return. The natives reported a worse place above our turning-point--the passage being still narrower than this. An Arab, they said, once built a boat above the rapids, and sent it down full of slaves; but it was broken to pieces in these upper narrows. Many still maintained that the Rovuma came from Nyassa, and that it is very narrow as it issues out of the lake. One man declared that he had seen it with his own eyes as it left the lake, and seemed displeased at being cross-questioned, as if we doubted his veracity. More satisfactory information, as it appeared to us, was obtained from others. Two days, or thirty miles, beyond where we turned back, the Rovuma is joined by the Liende, which, coming from the south-west, rises in the mountains on the east side of Nyassa. The great slave route to Kilwa runs up the banks of this river, which is only ankle-deep at the dry season of the year. The Rovuma itself comes from the W.N.W., and after the traveller passes the confluence of the Liende at Ngomano or "meeting-place," the chief of which part is named Ndonde, he finds the river narrow, and the people Ajawa. Crocodiles in the Rovuma have a sorry time of it. Never before were reptiles so persecuted and snubbed. They are hunted with spears, and spring traps are set for them. If one of them enters an inviting pool after fish, he soon finds a fence thrown round it, and a spring trap set in the only path out of the enclosure. Their flesh is eaten, and relished. The banks, on which the female lays her eggs by night, are carefully searched by day, and all the eggs dug out and devoured. The fish-hawk makes havoc among the few young ones that escape their other enemies. Our men were constantly on the look-out for crocodiles' nests. One was found containing thirty-five newly-laid eggs, and they declared that the crocodile would lay as many more the second night in another place. The eggs were a foot deep in the sand on the top of a bank ten feet high. The animal digs a hole with its foot, covers the eggs, and leaves them till the river rises over the nest in about three months afterwards, when she comes back, and assists the young ones out. We once saw opposite Tette young crocodiles in December, swimming beside an island in company with an old one. The yolk of the egg is nearly as white as the real white. In taste they resemble hen's eggs with perhaps a smack of custard, and would be as highly relished by whites as by blacks, were it not for their unsavoury origin in men-eaters.
