"Before long we entered upon the worst part of this canyon. Rapids Fourteen, Fifteen, and Sixteen are so close together that they must be run without stopping, as there is practically no quiet water between them; and so rocky is No. Sixteen that it seems impossible to get through at all. Loper proposed to run it with his boat, the _Arizona_, while we watched the result. He handled the craft very dexterously, being an excellent oarsman, and was successful in striking the only place in Rapid Sixteen that a boat could pass through. But even here the current dashed hard against a huge rock, taking a vertical drop of four or five feet off one side. Loper found it impossible to keep the boat away from this boulder and she was swept heavily against it. She turned almost on end, but luckily the water was deep and she came up like a fish. After seeing Loper's experience Monett and myself were fearful of our ability to get through, and Loper bravely volunteered to bring our boats through, which feat he accomplished in safety." [Illustration: "SHE TURNED ALMOST ON END."] When they had pulled themselves together and looked over the little fleet it was found that Loper's boat had been unfitted for further service by the collision with the rock, and the greater part of his supplies lost. After a consultation it was decided that the others should leave their unfortunate partner at a little settlement just below the cataract and proceed. Russell and Monett, pushing ahead, put in many days prospecting along the shores of Glen Canyon. They waited for Loper at Lee's Ferry, a Mormon settlement, more than twice as long as the time agreed upon. Then, as there were no signs of him, they determined to go on without him. Friday, the 13th of the month, had no terrors for the intrepid pair, and they started off down the river on the morning of that day, with the Marble Canyon acting as an introduction to the Grand Canyon below. In dwelling on this stage of their journey Russell seemed to lose sight entirely of the remarkable nerve both men showed in going through what is admittedly the wildest part of the river without the third companion who, at the outset, had seemed absolutely indispensable to the successful accomplishment of the trip. In seven days they had passed the length of the roaring stream through the perpendicular walls of Marble Canyon, towering up on either side to an average height of three thousand feet, and had come safely through the worst rapids up to that point. At one place there were fifty-seven rapids to be negotiated in quick succession, some of them having falls from sixteen to twenty feet deep.
