The river now widened so that in places it looked like a long lake; it wound in every direction through the endless marshy plain, whose surface was broken here and there by low mountains. The splendor of the sunset I never saw surpassed. We were steaming east toward clouds of storm. The river ran, a broad highway of molten gold, into the flaming sky; the far-off mountains loomed purple across the marshes; belts of rich green, the river banks stood out on either side against the rose-hues of the rippling water; in front, as we forged steadily onward, hung the tropic night, dim and vast.
No less than six weeks were spent in slowly and with peril and exhausting labor forcing our way down through what seemed a literally endless succession of rapids and cataracts. For forty-eight days we saw no human being. In passing these rapids we lost five of the seven canoes with which we started and had to build others. One of our best men lost his life in the rapids. Under the strain one of the men went completely bad, shirked all his work, stole his comrades’ food and when punished by the sergeant he with cold-blooded deliberation murdered the sergeant and fled into the wilderness.
