that we were still a considerable distance from the Ngami, we left all the oxen and wagons, except Mr. Oswell's, which was the smallest, and one team, at Ngabisane, in the hope that they would be recruited for the home journey, while we made a push for the lake. The Bechuana chief of the Lake region, who had sent men to Sechele, now sent orders to all the people on the river to assist us, and we were received by the Bakoba, whose language clearly shows that they bear an affinity to the tribes in the north. They call themselves Bayeiye, i.e., men; but the Bechuanas call them Bakoba, which contains somewhat of the idea of slaves. They have never been known to fight, and, indeed, have a tradition that their forefathers, in their first essays at war, made their bows of the Palma Christi, and, when these broke, they gave up fighting altogether. They have invariably submitted to the rule of every horde which has overrun the countries adjacent to the rivers on which they specially love to dwell. They are thus the Quakers of the body politic in Africa.
A long time after the period of our visit, the chief of the Lake, thinking to make soldiers of them, took the trouble to furnish them with shields. "Ah! we never had these before; that is the reason we have always succumbed. Now we will fight." But a marauding party came from the Makololo, and our "Friends" at once paddled quickly, night and day, down the Zouga, never daring to look behind them till they reached the end of the river, at the point where we first saw it.
The canoes of these inland sailors are truly primitive craft: they are hollowed out of the trunks of single trees by means of iron adzes; and if the tree has a bend, so has the canoe. I liked the frank and manly bearing of these men, and, instead of sitting in the wagon, preferred a seat in one of the canoes. I found they regarded their rude vessels as the Arab does his camel. They have always fires in them, and prefer sleeping in them while on a journey to spending the night on shore. "On land you have lions," say they, "serpents, hyaenas, and your enemies; but in your canoe, behind a bank of reed, nothing can harm you." Their submissive disposition leads to their villages being frequently visited by hungry strangers. We had a pot on the fire in the canoe by the way, and when we drew near the villages devoured the contents. When fully satisfied ourselves, I found we could all look upon any intruders with perfect complacency, and show the pot in proof of having devoured the last morsel.
While ascending in this way the beautifully-wooded river, we came to a large stream flowing into it. This was the River Tamunak'le. I inquired whence it came. "Oh, from a country full of rivers—so many no one can tell their number—and full of large trees." This was the first confirmation of statements I had heard from the Bakwains who had been with Sebituane, that the country beyond was not "the large sandy plateau" of the philosophers. The prospect of a highway capable of being traversed by boats to an entirely unexplored and very populous region, grew from that time forward stronger and stronger in my mind; so much so that, when we actually came to the lake, this idea occupied such a large portion of my mental vision that the actual discovery seemed of but little importance. I find I wrote, when the emotions caused by the magnificent prospects of the new country were first awakened in my breast, that they "might subject me to the charge of enthusiasm, a charge which I wished I deserved, as nothing good or great had ever been accomplished in the world without it."*

Twelve days after our departure from the wagons at Ngabisane we came to the northeast end of Lake Ngami; and on the 1st of August, 1849, we went down together to the broad part, and, for the first time, this fine-looking sheet of water was beheld by Europeans. The direction of the lake seemed to be N.N.E. and S.S.W. by compass. The southern portion is said to bend round to the west, and to receive the Teoughe from the north at its northwest extremity. We could detect no horizon where we stood looking S.S.W., nor could we form any idea of the extent of the lake, except from the reports of the inhabitants of the district; and, as they professed to go round it in three days, allowing twenty-five miles a day would make it seventy-five, or less than seventy geographical miles in circumference. Other guesses have been made since as to its circumference, ranging between seventy and one hundred miles. It is shallow, for I subsequently saw a native punting his canoe over seven or eight miles of the northeast end; it can never, therefore, be of much value as a commercial highway. In fact, during the months preceding the annual supply of water from the north, the lake is so shallow that it is with difficulty cattle can approach the water through the boggy, reedy banks. These are low on all sides, but on the west there is a space devoid of trees, showing that the waters have retired thence at no very ancient date. This is another of the proofs of desiccation met with so abundantly throughout the whole country. A number of dead trees lie on this space, some of them imbedded in the mud, right in the water. We were informed by the Bayeiye, who live on the lake, that when the annual inundation begins, not only trees of great size, but antelopes, as the springbuck and tsessebe ('Acronotus lunata'), are swept down by its rushing waters; the trees are gradually driven by the winds to the opposite side, and become imbedded in mud.
The water of the lake is perfectly fresh when full, but brackish when low; and that coming down the Tamunak'le we found to be so clear, cold, and soft, the higher we ascended, that the idea of melting snow was suggested to our minds. We found this region, with regard to that from which we had come, to be clearly a hollow, the lowest point being Lake Kumadau; the point of the ebullition of water, as shown by one of Newman's barometric thermometers, was only between 207–½ Deg. and 206 Deg., giving an elevation of not much more than two thousand feet above the level of the sea. We had descended above two thousand feet in coming to it from Kolobeng. It is the southern and lowest part of the great river system beyond, in which large tracts of country are inundated annually by tropical rains, hereafter to be described. A little of that water, which in the countries farther north produces inundation, comes as far south as 20d 20', the latitude of the upper end of the lake, and instead of flooding the country, falls into the lake as into a reservoir. It begins to flow down the Embarrah, which divides into the rivers Tzo and Teoughe. The Tzo divides into the Tamunak'le and Mababe; the Tamunak'le discharges itself into the Zouga, and the Teoughe into the lake. The flow begins either in March or April, and the descending waters find the channels of all these rivers dried out, except in certain pools in their beds, which have long dry spaces between them. The lake itself is very low. The Zouga is but a prolongation of the Tamunak'le, and an arm of the lake reaches up to the point where the one ends and the other begins. The last is narrow and shallow, while the Zouga is broad and deep. The narrow arm of the lake, which on the map looks like a continuation of the Zouga, has never been observed to flow either way. It is as stagnant as the lake itself.
The Teoughe and Tamunak'le, being essentially the same river, and receiving their supplies from the same source (the Embarrah or Varra), can never outrun each other. If either could, or if the Teoughe could fill the lake—a thing which has never happened in modern times—then this little arm would prove a convenient escapement to prevent inundation. If the lake ever becomes lower than the bed of the Zouga, a little of the water of the Tamunak'le might flow into it instead of down the Zouga; we should then have the phenomenon of a river flowing two ways; but this has never been observed to take place here, and it is doubtful if it ever can occur in this locality. The Zouga is broad and deep when it leaves the Tamunak'le, but becomes gradually narrower as you descend about two hundred miles; there it flows into Kumadau, a small lake about three or four miles broad and twelve long. The water, which higher up begins to flow in April, does not make much progress in filling this lake till the end of June. In September the rivers cease to flow. When the supply has been more than usually abundant, a little water flows beyond Kumadau, in the bed first seen by us on the 4th of July; if the quantity were larger, it might go further in the dry rocky bed of the Zouga, since seen still further to the east. The water supply of this part of the river system, as will be more fully explained further on, takes place in channels prepared for a much more copious flow. It resembles a deserted Eastern garden, where all the embankments and canals for irrigation can be traced, but where, the main dam and sluices having been allowed to get out of repair, only a small portion can be laid under water. In the case of the Zouga the channel is perfect, but water enough to fill the whole channel never comes down; and before it finds its way much beyond
