Suddenly they heard yells in the rear, accompanied by pistol shots and the cracking of quirts. In an instant the herd was up with distended eyeballs and lifted tails. The poison of fear was in them.

Looking back, Ted saw several men riding toward the herd at a terrific pace. At the head of the band rode Shan Rhue and Sol Flatbush.

Then a remarkable thing happened: Every man of them produced a red blanket. They dashed among the cattle waving the blankets in the faces of the now terrified cattle.

"Look out for trouble," shouted Ted, for he saw at once the intention of Shan Rhue. It was to stampede the herd.

The effort was immediately successful, for the terrified animals, with a deafening roar that expressed abject fear, started forward on a gallop, with a front as resistless as the prow of a battleship.

Stella was on the side of the herd opposite Ted.

She heard his warning cry, and then looked back at the herd. If she stayed where she was, there was no escape from death, for by her side was the sheer wall of the valley. There was only one way to safety, to ride across to the side of Ted.

She gave one look, then started.

Stella rode quartering the path of the stampede, and would have made it in safety had it not been for a prairie-dog hole, into which her pony's foot went. Magpie went down. The thundering host of frantic cattle was upon her when she felt herself caught in mid-air.

The thought of death was still ringing in her head, and everything swam before her eyes.
