The jutting point, stripped bare of trees, was cut as clean as though some great knife had sliced it. Under its new front the river had cut in until, as they looked, the whole face of the bluff slid down into the stream, a slice twenty feet thick damming the current and turning it into a raging fury. Some hundreds of yards behind the doomed point the muddy torrent boiled and seethed through its new channel, vomiting trees, stumps, brush and miscellaneous rubbish in an endless stream. Off the point, and also where the two great currents came together again behind it two great whirlpools revolved with sloping surfaces smooth as ice, around which swept driftwood with a speed not unlike the horses of some great merry-go-round. The vortex of the one off the point was easily ten feet below the rim of its circumference, and the width of the entire affair was greater than the length of the boat. A peeled log, not quite water-soaked, reached the center and arose as vertical as a plumb line, swayed in short, quick circles and then dove from sight. A moment later it leaped from the water well away from the pool and fell back with a smack which the noise of the wind did not drown. To starboard was a rhythmic splashing of bare limbs, where a great cottonwood, partly submerged, bared its fangs. To the right of that was a towhead, a newly formed island of mud and sand partly awash. The pilot cursed softly and jerked on the bell handle, the boat instantly falling into half speed. He did not dare to cut across the whirlpool, the snag barred him dead ahead, and it was doubtful if there was room to pass between it and the towhead; but he had no choice in the matter and he rang again, the boat falling into bare steerageway. If he ran aground he would do so gently and no harm would be done. So swift was the current that the moment he put the wheel over a few spokes and shifted the angle between the keel-line and the current direction, the river sent the craft sideways so quickly that before he had stopped turning the wheel in the first direction he had to spin it part way back again. The snag now lay to port, the towhead to starboard, and holding a straight course the _Missouri Belle_ crept slowly between them. There came a slight tremor, a gentle lifting to port, and he met it by a quick turn of the wheel. For a moment the boat hung pivoted, its bow caught by a thrusting side current and slowly swinging to port and the snag. A hard yank on the bell handle was followed by a sudden forward surge, a perceptible side-slip, a gentle rocking, and the bow swung back as the boat, entirely free again, surged past both dangers. The pilot heaved a sigh of relief. "Peterson didn't say nothin' about th' snag or th' towhead," he growled. Then he grinned. "I bet he rounded inter th' edge o' th' whirler afore he knowed it was thar! Now that I recollect it he did seem a mite excited."
