In another place Stanley says: "Livingstone followed the dictates of duty. Never was such a willing slave to that abstract virtue. His inclinations impel him home, the fascinations of which it requires the sternest resolution to resist. With every foot of new ground he travelled over he forged a chain of sympathy which should hereafter bind the Christian nations in bonds of love and charity to the heathen of the African tropics. If he were able to complete this chain of love by actual discovery, and, by a description of them, to embody such people and nations as still live in darkness, so as to attract the good and charitable of his own land to bestir themselves for their redemption and salvation, this Livingstone would consider an ample reward. "Surely, as the sun shines on both Christian and infidel, civilised and pagan, the day of enlightenment will come; and though the apostle of Africa may not behold it himself, nor we younger men, nor yet our children, the hereafter will see it, and posterity will recognise the daring pioneer of its civilisation." Yes, and Stanley might have added: with his enlarged and far-seeing mind, this it is what encourages Livingstone to persevere in his task to do what he knows no other man can do as well. It might be far pleasanter to tell crowded congregations at home about the wrongs of the sons and daughters of Africa, but, with the spirit of a true apostle, he remains among those whose wrongs it is the ardent desire of his soul to right, that he may win their love and confidence, and open up the way by which others may with greater ease continue the task he has commenced. After they had been some weeks together at Ujiji, Stanley and Livingstone agreed to make a voyage on Lake Tanganyika, one of the chief objects of which was to settle the long mooted point as to whether the Rusizi river is an effluent or an influent. They embarked in a somewhat cranky canoe, hollowed-out of a mvule-tree, which carried sixteen rowers, Selim, Ferajji, the cook, and two guides, besides themselves. The lake was calm, its waters of a dark green colour, reflecting the serene blue sky above. The hippopotami came up to breathe in close proximity to the canoe, and then plunged down again, as if playing at hide and seek with them. At one place where they sounded, the depth was found to be thirty-five fathoms near the shore, and further out a hundred and fifteen fathoms of line was let down without finding bottom, and the doctor stated that he had sounded opposite the lofty Kabogo, and attained the depth of three hundred fathoms. A range of hills, beautifully wooded and clothed with green grass, sloping abruptly--almost precipitately--into the depth of the fresh-water, towered above them, and as they rounded the several capes or points, high expectations of some new wonder or some exquisite picture being revealed to them were aroused: nor were they disappointed.
