The lake was known to extend as far south as Karagwe; and the old story was repeated, that Rumanika, the king of that country, was in the habit of sending ivory-hunting parties to the lake at Utumbi, and that formerly they had navigated the lake to Magungo. This was a curious confirmation of the report given me by Speke at Gondokoro, who wrote: "Rumanika is constantly in the habit of sending ivory-hunting parties to Utumbi."

The eastern shores of the lake were, from north to south, occupied by Chopi, Unyoro, Uganda, Utumbi, and Karagwe: from the last point, which could not be less than about two degrees south latitude, the lake was reported to turn suddenly to the west, and to continue in that direction for an unknown distance. North of Malegga, on the west of the lake, was a small country called M'Caroli; then Koshi, on the west side of the Nile at its exit from the lake; and on the east side of the Nile was the Madi, opposite to Koshi. Both the guide and the chief of Vacovia informed me that we should be taken by canoes to Magungo, to the point at which the Somerset that we had left at Karuma joined the lake; but that we could not ascend it, as it was a succession of cataracts the whole way from Karuma until within a short distance of Magungo. The exit of the Nile from the lake at Koshi was navigable for a considerable distance, and canoes could descend the river as far as the Madi.

They both agreed that the level of the lake was never lower than at present, and that it never rose higher than a mark upon the beach that accounted for an increase of about four feet. The beach was perfectly clean sand, upon which the waves rolled like those of the sea, throwing up weeds precisely as seaweed may be seen upon the English shore. It was a grand sight to look upon this vast reservoir of the mighty Nile, and to watch the heavy swell tumbling upon the beach, while far to the southwest the eye searched as vainly for a bound as though upon the Atlantic. It was with extreme emotion that I enjoyed this glorious scene. My wife, who had followed me so devotedly, stood by my side pale and exhausted—a wreck upon the shores of the great Albert lake that we had so long striven to reach. No European foot had ever trod upon its sand, nor had the eyes of a white man ever scanned its vast expanse of water. We were the first; and this was the key to the great secret that even Julius Caesar yearned to unravel, but in vain. Here was the great basin of the Nile that received EVERY DROP OF WATER, even from the passing shower to the roaring mountain torrent that drained from Central Africa towards the north. This was the great reservoir of the Nile!

The first coup d'oeil from the summit of the cliff 1,500 feet above the level had suggested what a closer examination confirmed. The lake was a vast depression far below the general level of the country, surrounded by precipitous cliffs, and bounded on the west and southwest by great ranges of mountains from five to seven thousand feet above the level of its waters—thus it was the one great reservoir into which everything MUST drain; and from this vast rocky cistern the Nile made its exit, a giant in its birth. It was a grand arrangement of Nature for the birth of so mighty and important a stream as the river Nile. The Victoria N'yanza of Speke formed a reservoir at a high altitude, receiving a drainage from the west by the Kitangule river, and Speke had seen the M'fumbiro mountain at a great distance as a peak among other mountains from which the streams descended, which by uniting formed the main river Kitangule, the principal feeder of the Victoria lake from the west, in about the 2 degrees S. latitude: thus the same chain of mountains that fed the Victoria on the east must have a watershed to the west and north that would flow into the Albert lake. The general drainage of the Nile basin tending from south to north, and the Albert lake extending much farther north than the Victoria, it receives the river from the latter lake, and thus monopolizes the entire headwaters of the Nile. The Albert is the grand reservoir, while the Victoria is the eastern source, the parent streams that form these lakes are from the same origin, and the Kitangule sheds its waters to the Victoria to be received eventually by the Albert, precisely as the highlands of M'fumbiro and the Blue Mountains pour their northern drainage direct into the Albert lake. The entire Nile system, from the first Abyssinian tributary the Atbara in N. latitude 17 deg. 37 min. even to the equator, exhibits a uniform drainage from S.E. to N.W., every tributary flowing in that direction to the main stream of the Nile; this system is persisted in by the Victoria Nile, which having continued a northerly course from its exit from the Victoria lake to Karuma in lat. 2 degrees 16' N. turns suddenly to the west and meets the Albert lake at Magungo; thus, a line drawn from Magungo to the Ripon Falls from the Victoria lake will prove the general slope of the country to be the same as exemplified throughout the entire system of the eastern basin of the Nile, tending from S.E. to N.W.

That many considerable affluents flow into the Albert lake there is no doubt. The two waterfalls seen by telescope upon the western shore descending from the Blue Mountains must be most important streams, or they could not have been distinguished at so great a distance as fifty or sixty miles; the natives assured me that very many streams, varying in size, descended the mountains upon all sides into the general reservoir.

I returned to my hut: the flat turf in the vicinity of the village was strewn with the bones of immense fish, hippopotami, and crocodiles; but the latter reptiles were merely caught in revenge for any outrage committed by them, as their flesh was looked upon with disgust by the natives of Unyoro. They were so numerous and voracious in the lake, that the natives cautioned us not to allow the women to venture into the water even to the knees when filling their water jars.

It was most important that we should hurry forward on our journey, as our return to England depended entirely upon the possibility of reaching Gondokoro before the end of April, otherwise the boats would have departed. I impressed upon our guide and the chief that we must be furnished with large canoes immediately, as we had no time to spare, and I started off Rabonga to Magungo, where he was to meet us with our riding oxen. The animals would be taken by a path upon the high ground; there was no possibility of travelling near the lake, as the cliffs in many places descended abruptly into deep water. I made him a present of a large quantity of beads that I had promised to give him upon reaching the lake; he took his departure, agreeing to meet us at Magungo with our oxen, and to have porters in readiness to convey us direct to Shooa.

On the following morning not one of our party could rise from the ground. Thirteen men, the boy Saat, four women, and we ourselves, were all down with fever. The air was hot and close, and the country frightfully unhealthy. The natives assured us that all strangers suffered in a similar manner, and that no one could live at Vacovia without repeated attacks of fever.

The delay in supplying the boats was most annoying; every hour was precious; and the lying natives deceived us in every manner possible, delaying us purposely in the hope of extorting beads.

The latitude of Vacovia was 1 degree 15 min. N.; longitude 30 degrees 50 min. E. My farthest southern point on the road from M'rooli was latitude 1 degree 13 minutes. We were now to turn our faces towards the north, and every day's journey would bring us nearer home. But where was home? As I looked at the map of the world, and at the little red spot that represented old England far, far away, and then gazed on the wasted form and haggard face of my wife and at my own attenuated frame, I hardly dared hope for home again. We had now been three years ever toiling onwards, and having completed the exploration of all the Abyssinian affluents of the Nile, in itself an arduous undertaking, we were now actually at the Nile head. We had neither health nor supplies, and the great journey lay all before us.
