In a flash the auto had turned the bend in the river road, and the occupants saw the toll-bridge and the peaceful hamlet of Culm Falls. There was no stir there. The toll-bridge keeper was not even out of his cottage, and the light and flimsy gates were down across the driveway at either end of the bridge. The bend in the river hid the advancing wall of water. Perhaps, too, it deadened the sound of the bursting dam and the roar of the waters. There was another house at the bend. Helen tooted the automobile horn as though it had gone crazy. The raucous notes must of a certainty have awakened anybody but the Seven Sleepers. But the three in the car saw no sign of life about the premises. Helen had started to slow down; but Tom stopped her with a hand on her arm. "Not here! Not here!" he yelled. "Get across the river first, Nell! That wave is coming!" Indeed it was. And the toll-bridge keeper did not appear, and the gates were shut. But Helen Cameron was excited now and her racing blood was up. She never hesitated at the frail barrier, but drove straight through it, smashing the gate to kindling wood, and smashing their own wind shield as well. Out ran the toll-man then; but they were half way across the bridge; he could barely have raised the other gate had he set about it instantly. So they went through that, too, leaving him bawling and shrieking after them, but soon to learn by looking up the river what Tom meant by his excited words as the motor car swept by. Helen slowed down at the smithy. There were several men there and a number of wagons. The trio in the car screamed at them: "The dam has burst! The flood is coming!" and then started up again and swept through the little village, looking back to see the group at the smithy running in all directions to give the alarm. Now the road, clear to the Red Mill and beyond, ran within sight of the river. The mill was all of ten miles away. The valley was low here and as far as they could see ahead it broadened considerably on this side of the Lumano. But the hills arose abruptly on the farther bank and all the force and mass of the flood must sweep across these meadows. As the car moved on, Helen tooted the horn constantly. Its blasts alone should have warned people of what threatened, without Tom's frantic shouts and gesticulations. They were obliged, however, to slow down before several houses to make the occupants understand their danger. They were not half way to the Red Mill when the roar of the advancing tidal wave was apparent even above the noise of the auto. Then they saw the crest of the flood appear around the bend and the already heavily burdened waters dashed themselves upon the toll-bridge. It crumpled up and disappeared like a spider-web bridge, and the flood rolled on, the wave widening and overflowing the lowlands behind the automobile.
