At my request, Mahaya assembled all his principal men, and we went into a discussion about the lake; but not a soul knew anything about its northern extremity, although people had sometimes travelled in canoes, coasting along its shores by the Karagué district to as far, I believe, as the Line.[61] His wife, a pretty crummy little creature of the Wanyoro tribe, came farther from the north than anybody present, and gave me the names of many districts in the Uganda country, which, she says, lies along the seashore. She had never heard of there being any end to the lake, and supposed, if any way of going round it did exist, she would certainly have known it. It is well known that there is no communication between the east and west shores of the lake, excepting by a few occasional canoe-parties coasting along the southern end, because the waters are so very broad they dare not venture.[62] That there can be no high mountain-range intersecting the N'yanza from the watercourses which we hear of north of the equator, as some people have supposed, is evident from the numerous accounts given of the kingdom of Uganda being so flat and marshy from the equator to 2° or 3° north latitude; whilst I must have seen any, did they exist, on the south side of the equator, being only 150 miles from it when standing on its southern shore. Now, judging from all the information given us by the several Egyptian expeditions and missionaries sent up the Nile, who came across small hills in 4½° north latitude and 32° east longitude, which are intersected by the Nile in the same way that the East Coast Range is intersected by the interior plateau rivers (Lufiji and Kingani), as we saw on our passage inwards from Zanzibar; and further, by the Arabs telling us that all the country on the same meridian, from the Line up to the second parallel north latitude, is flat and full of watercourses; and then again, by knowing the respective heights of the N'yanza on the one side, being nearly 4000 feet, and the Nile's bed in latitude 5° N., or beyond the small hills alluded to, being under 2000 feet--it would indeed be a marvel if this lake is not the fountain of the Nile.[63] The reason why those expeditions sent up the Nile have failed in discovering the N'yanza, is clearly attributable to the important rapids which must exist in consequence of this great variation of altitude between the north end of the N'yanza (which, let us suppose, is on the equator) and the position, in 4° 44' north latitude, at which the expeditions and missions arrived, the rise of the river being 2000 feet in 300 miles.
