Caught in the mass of maddened cattle, the girls might easily be unseated and trampled to death. Ruth knew this as well as did the Western girl. But if the sound of the human voice would help to keep the creatures within bounds, the girl from the Red Mill determined to sing on and ride closer in line with the milling herd.

She missed Jane Ann after a moment; but another flash of lightning revealed her friend weaving her pony in and out through the pressing cattle, using the quirt with free hand on the struggling steers and breaking them up into small groups.

The cowboys who had dashed out of the coulie saw the possibility of disaster instantly; and they, too, rode in among the bellowing steers. With so many heavy creatures pressing toward a common center, many would soon be crushed to death if the formation was not broken up. Each streak of lightning which played athwart the clouds added to the fear of the beasts. Several of the punchers rode close along the edge of the herd, driving in the strays. Now it began to rain, and as the very clouds seemed to open and empty the water upon the thirsty land, the swish of it, and the moaning of the wind that arose, added greatly to the confusion.

How it did rain for a few minutes! Ruth felt as though she were riding her pony beneath some huge water-spout. She was thankful for the slicker, off which the water cataracted. The pony splashed knee-deep through runlets freshly started in the old buffalo paths. Here and there a large pond of water gleamed when the lightning lit up their surroundings.

And when the rain stopped as abruptly as it had begun, the cattle began to steam and were more troublesome than before. The lightning flashes and thunder continued, and when a second downpour of rain began it came so viciously, and with so great a wind, that the girls could scarcely ride against it.

Suddenly a shout came down the wind. It was taken up and repeated by voice after voice. The camp at the far end of the herd had been aroused ere this, of course, and every man who could ride was in the saddle. But it was at the camp-end of the herd, after all, that the first break came.

“They’re off!” yelled Darcy, riding furiously past Ruth and Jane Ann toward where the louder disturbance had arisen.

“And toward the river!” shouted another of the cowboys.

The thunder of hoofs in the distance suddenly rose to a deafening sound. The great herd had broken away and were tearing toward the Rolling River at a pace which nothing could halt. Several of the cowboys were carried forward on the fore-front of the wave of maddened cattle; but they all managed to escape before the leaders reached the high bank of the stream.

Jane Ann screamed some order to Ruth, but the latter could not hear what it was. Yet she imitated the Western girl’s efforts immediately. No such tame attempts at controlling the cattle as singing to them was now in order. The small number of herdsmen left at this point could only force their ponies into the herd and break up the formation—driving the mad brutes back with their quirts, and finally, after a most desperate fight, holding perhaps a third of the great herd from running wildly into the stream.
