Circumnavigation Completed.

the coast rose a mountain not less than four thousand feet high, to which I o-ave the name of Nubar. At the extreme end of the lake a semicircle of mountains was seen, and I supposed that the lake ended there.

We lost several hours in seeking a passage to the shore, to be able to converse with the natives, but the banks are here unapproachable on account of the ambash, the papyrus, and the bamboos, which hedge them in for a quarter of a mile. At last we descried a fishing-boat, but it speedily disappeared. We then tried to follow the same way, and after two hours we landed ; but the inhabitants of the place ran up threateningly, desiring us to return on board. Wadel-Mek had given me a man to accompany us who understood the language of these people, but whatever questions and propositions were made to them, they only answered, " Go away; we don't want you." Meanwhile the native soldiers hastened from all the seribe around ; it was already late, and it was necessary to seek refuge for the night out of reach of these warlike people.

April 20th. — We made a fresh attempt. I approached with the boat, and the natives came running up in great numbers. By means of the interpreter I' promised them presents if they would point out to me the way I must take. They replied that it was impossible for us to go on, because the lake ended at this point.

" But I want to see the river there is at the end." " There is no river." " Then there is a cascade? " " There is not one, but three cascades at the end." " Whence comes the water of these cascades ? " " From a river."

" Is that river always full of water ? " " No ; only at the time of the rains." " And here, where we are, is the water also lower when it does not rain ? " " Not much ; it is almost always the same."
