or gorillas must have been a step in the process of teaching them to eat men.  The sight of a soko nauseates me.  He is so hideously ugly, I can conceive no other use for him than sitting for a portrait of Satan.  I have lost many months by rains, refusal of my attendants to go into a canoe, and irritable eating ulcers on my feet from wading in mud instead of sailing.  They are frightfully common, and often kill slaves.  I am recovering, and hope to go down Lualaba, which I would call Webb River or Lake; touch then another Lualaba, which I will name Young’s River or Lake; and then by the good hand of our Father above turn homeward through Karagwe.  As ivory-trading is here like gold-digging, I felt constrained to offer a handsome sum of money and goods to my friend Mohamad Bogharib for men.  It was better to do this than go back to Ujiji, and then come over the whole 260 miles.  I would have waited there for men from Zanzibar, but the authority at Ujiji behaved so oddly about my letters, I fear they never went to the coast.  The worthless slaves I have saw that I was at their mercy, for no Manyuema will go into the next district, and they behaved as low savages who have been made free alone can.  Their eagerness to enslave and kill their own countrymen is distressing....

“A Dutch lady whom I never saw, and of whom I know nothing save from scraps in the newspapers, moves my sympathy more than any other.  By her wise foresight in providing a steamer, and pushing on up the river after the severest domestic affliction—­the loss by fever of her two aunts—­till after she was assured by Speke and Grant that they had already discovered in Victoria Nyanza the sources she sought, she proved herself a genuine explorer, and then by trying to go S.W. on land.  Had they not, honestly enough of course, given her their mistaken views, she must inevitably, by boat or on land, have reached the head-waters of the Nile.  I cannot conceive of her stopping short of Bangweolo.  She showed such indomitable pluck she must be a descendant of Van Tromp, who swept the English Channel till killed by our Blake, and whose tomb every Englishman who goes to Holland is sure to visit.

“We great he-beasts say, ’Exploration was not becoming her sex.’  Well, considering that at least 1600 years have elapsed since Ptolemy’s
