Fine particles of the sharpest crystal were driven in a thick haze through the singing air. Nell instantly whipped off her neckcloth and tied it across her nose and mouth, warning Betty to follow her example.

“Get this in your lungs, Betty, and you’ll have pneumonia as sure as sure!” she shouted.

Frightened, they urged their ponies on to the beginning of the rough path down the canyon wall. Although they were soon somewhat sheltered from the driving ice-storm there were bare places where the two girls suffered the full force of the gale.

“I know a place!” cried Nell in a muffled voice. “We got to hole up till this stops. Come on!”

It had grown dark of a sudden. Nell pulled her pony off the path, and he picked his way daintily to a cavity in the wall. Here an overhanging rock offered some shelter. At least, the girls were out of the steady beat of the storm.

They dismounted and got behind the ponies, between their warm bodies and the rock itself. If Betty was the more frightened of the two, she showed it no more than did Nell Blossom.

The air became thicker and the whine of the wind rose to a shriek which all but drowned their voices when they tried to communicate with each other. It was such a manifestation of the storm king as Betty Hunt had never seen before.

They were but a little way off the path. Suddenly both girls, in spite of the wind, heard the clatter of shod hoofs. Another horse was coming down the path. In a moment they dimly saw the looming figure of a man leading the animal.

“Who is it?” gasped Betty, but if Nell heard the question she did not answer.

Nell clutched Betty’s wrist for silence. The girls stared at the man beating his way downward. He wore a broad-brimmed hat, but they could see the long, black, curling hair flowing from beneath it. He turned his face toward them, and Betty beheld the keen face and heavy mustache of the stranger she had seen hiding from the sheriff and his posse weeks before near the trail to Hoskins!
