They glided rapidly along the foot of the wall, grazing one large rock, and then they pulled into the falls and plunged over them. The open compartment of the major's boat was filled when she struck the first wave below, but she cut through the upheaval, and by vigorous strokes was drawn away from the dangerous rock farther down. They were scarcely a minute in running through the rapids, and found that what had seemed almost hopeless from above was really less difficult than many other points on the river. The Rowlands and their companion were now out of sight, and guns were fired to indicate to them that the passage had been safely made and to induce them to follow; but no answer came, and after waiting two hours the descent of the river was resumed. [Illustration: CANON IN ESCALANTE BASIN.] A succession of falls and rapids still had to be overcome, and in the afternoon the explorers were once more threatened with defeat. A little stream entered the canon from the left, and immediately below the river broke over two falls, beyond which it rose in high waves and subsided in whirlpools. The boats hugged the left wall for some distance, but when the men saw that they could not descend on this side they pulled up stream several hundred yards and crossed to the other. Here there was a bed of basalt about one hundred feet high, which, disembarking, they followed, pulling the boats after them by ropes. The major, as usual, went ahead, and discovered that it would be impossible to lower the boats from the cliff; but the men had already brought one of them to the brink of the falls and had secured her by a bight around a crag. The other boat, in which Bradley had remained, was shooting in and out from the cliffs with great violence, now straining the line by which she was held, and now whirling against the rock as if she would dash herself to pieces. An effort was made to pass another rope to Bradley, but he was so preoccupied that he did not notice it, and the others saw him take a knife out of its sheath and step forward to cut the line. He had decided that it was better to go over the falls with her than to wait for her to be completely wrecked against the rocks. He did not show the least alarm, and as he leaned over to cut the rope the boat sheered into the stream, the stern-post broke and he was adrift. With perfect composure he seized the large scull-oar, placed it in the stern rowlock and pulled with all his strength, which was considerable, to turn the bow down stream. After the third stroke she passed over the falls and was invisible for several seconds, when she reappeared upon a great wave, dancing high over its crest, then sinking between two vast walls of water. The men on the cliff held their breath as they watched. Again she disappeared, and this time was out of sight so long that poor Bradley's fate seemed settled; but in a moment more something was noticed emerging
