was a man of scientific attainments, and Governor of Tette, but finding Cazembe at the rivulet called Chungu, he unfortunately succumbed to fever ten days after his arrival.  He seemed anxious to make his way across to Angola.  Misled by the similarity of Chambeze to Zambesi, they all thought it to be a branch of the river that flows past Tette, Senna, and Shupanga, by Luabo and Kongone to the sea.

“I rather stupidly took up the same idea from a map saying ‘Zambesi’ (eastern branch), believing that the map printer had some authority for his assertion.  My first crossing was thus as fruitless as theirs, and I was less excusable, for I ought to have remembered that while Chambeze is the true native name of the northern river, Zambesi is not the name of the southern river at all.  It is a Portugese corruption of Dombazi, which we adopted rather than introduce confusion by new names, in the same way that we adopted Nyassa instead of Nyanza ia Nyinyesi == Lake of the Stars, which the Portuguese, from hearsay, corrupted into Nyassa.  The English have been worse propagators of nonsense than Portuguese.  ‘Geography of Nyassa’ was thought to be a learned way of writing the name, though ‘Nyassi’ means long grass and nothing else.  It took me twenty-two months to eliminate the error into which I was led, and then it was not by my own acuteness, but by the chief Cazembe, who was lately routed and slain by a party of Banyamwezi.  He gave me the first hint of the truth, and that rather in a bantering strain:  ’One piece of water is just like another; Bangweolo water is just like Moero water, Chambeze water like Luapula water; they are all the same; but your chief ordered you to go to the Bangweolo, therefore by all means go, but wait a few days, till I have looked out for good men as guides, and good food for you to eat,’ etc. etc.

“I was not sure but that it was all royal chaff, till I made my way back south to the head-waters again, and had the natives of the islet Mpabala slowly moving the hands all around the great expanse, with 183 deg. of sea horizon, and saying that is Chambeze, forming the great Bangweolo, and disappearing behind that western headland to change its name to Luapula, and run down past Cazembe to Moero.  That was the moment of discovery, and not my passage or the Portuguese passage of the river.  If, however, any one chooses to claim for them the discovery of Chambeze as one line of drainage of the Nile Valley, I shall not fight with him; Culpepper’s astrology was in the same way the forerunner of the Herschels’ and the other astronomers that followed.”

To another old friend, Mr. James Young, he wrote about the same time:  “Opere peracto ludemus—­the work being finished, we will play—­you remember in your Latin Rudiments lang syne.  It is true for you, and I rejoice to think it is now your portion, after working nobly, to play.  May you have a long spell of it!  I am differently situated; I
