On Tuesday morning, July 14, at six o'clock, we paddled away from the island to the foot of the lake. The outlet is entirely obscured by reeds and wild rice, through which the water converges in almost imperceptible current toward the river's first definite banks. This screen penetrated, I stopped the Kleiner Fritz in mid-stream and accurately measured width, depth and current. I found the width twenty feet, the depth on either side of my canoe as she pointed down the stream thirty-one inches, and the speed of the current two and one-tenth miles to the hour. The first four miles of the infant's course is swift and crooked, over a bed of red sand and gravel, thickly interspersed with mussel and other small shells, and bordered with reeds. Through these, at two points, we beat our way on foot, dragging the canoes through unmade channels. Indeed, nearly all of these first four miles demanded frequent leaps from the boats to direct their swift and crooked course, until we came to a stretch of savanna country, through which the river washes its way in serpentine windings for nine miles with a gentle current from thirty to sixty feet wide, bordered by high grass, bearing the appearance and having the even depth of a canal. An easy, monotonous paddle through these broad meadows brought us to the head of the first rapids, the scene of our two days' upward struggle. These rapids extend about twelve miles as the river runs, alternating between rattling, rocky plunges and swift, smooth water, for the most part through a densely-wooded ravine cleft through low but abrupt hills, and as lonely and cheerless as the heart of Africa. The solitude is of that sort which takes hold upon the very soul and weaves about it hues of the sombrest cast. From our parting with the Indians on first reaching the river we had neither seen nor heard a human being, nor were there save here and there remote traces of man's hand. No men dwell there: nothing invites men there. A few birds and fewer animals hold absolute dominion. Wandering there, one's senses become intensely alert. But for the hoot of the owl, the caw of the crow, the scream of the eagle, the infrequent twitter of small birds, the mighty but subdued roar of insects, the rush of water over the rocks and the sigh and sough of the wind among the pines, the lonely wanderer has no sign of aught but the rank and dank vegetation and a gloomy, oppressive plodding on and on, without an instant's relief in the sights and sounds of human life. We entered upon the descent of the rapids in no very cheerful mood.
