The lake was quite calm; its waters, of a dark-green colour, reflected the serene blue sky above. The hippopotami came up to breathe in alarmingly close proximity to our canoe, and then plunged their heads again, as if they were playing hide-and-seek with us. Arriving opposite the high wooded hills of Bemba, and being a mile from shore, we thought it a good opportunity to sound the depth of the water, whose colour seemed to indicate great depth. We found thirty-five fathoms at this place. Our canoeing of this day was made close in-shore, with a range of hills, beautifully wooded and clothed with green grass, sloping abruptly, almost precipitously, into the depths of the fresh-water sea, towering immediately above us, and as we rounded the several capes or points, roused high expectations of some new wonder, or some exquisite picture being revealed as the deep folds disclosed themselves to us. Nor were we disappointed. The wooded hills with a wealth of boscage of beautiful trees, many of which were in bloom, and crowned with floral glory, exhaling an indescribably sweet fragrance, lifting their heads in varied contour--one pyramidal, another a truncated cone; one table-topped, another ridgy, like the steep roof of a church; one a glorious heave with an even outline, another jagged and savage-interested us considerably; and the pretty pictures, exquisitely pretty, at the head of the several bays, evoked many an exclamation of admiration. It was the most natural thing in the world that I should feel deepest admiration for these successive pictures of quiet scenic beauty, but the Doctor had quite as much to say about them as I had myself, though, as one might imagine, satiated with pictures of this kind far more beautiful--far more wonderful--he should long ago have expended all his powers of admiring scenes in nature. From Bagamoyo to Ujiji I had seen nothing to compare to them--none of these fishing settlements under the shade of a grove of palms and plantains, banians and mimosa, with cassava gardens to the right and left of palmy forests, and patches of luxuriant grain looking down upon a quiet bay, whose calm waters at the early morn reflected the beauties of the hills which sheltered them from the rough and boisterous tempests that so often blew without.
