“Come on!” said Heavy. “Don’t let’s show the white feather. These folks will think we haven’t any pluck at all. Eastern girls can be just as courageous as Western girls, I believe.”

But all the time Ruth was puzzling over something that the cowboy, Scrub Weston, had said when he gave warning of the fire. He had mentioned Tintacker and suggested that the fire had been set by somebody whom Ruth supposed the cowboys must think was crazy—otherwise she could not explain that expression, “Bughouse Johnny.” These range riders were very rough of speech, but certainly their language was expressive!

This Tintacker Mine in which she was so deeply interested—for Uncle Jabez’s sake—must be very near the ranch. Ruth desired to go to the mine and learn if it was being worked; and she proposed to learn the whole history of the claim and look up the recording of it, as well. Of course, the young man who had gotten Uncle Jabez to invest in the silver mine had shown him deeds and the like; but these papers might have been forged. Ruth was determined to clear up the mystery of the Tintacker Mine before she left Silver Ranch for the East again.

Just now, however, she as well as the other guests of Jane Ann Hicks was excited by the fire on the range. They got jackets, and by the time all the girls were ready Maria’s husband had a pair of half-wild ponies hitched to the buckboard. Bob elected to drive the ponies, and he and the five girls got aboard the vehicle while the restive ponies were held by the Mexican.

Tom and Jane Ann had each saddled a pony. Jane Ann rode astride like a boy, and she was up on a horse that seemed to be just as crazy as he could be. Her friends from the East feared all the time that Jane Ann would be thrown.

“Let ’em go, Jose!” commanded the Silver Ranch girl. “You keep right behind me, Mr. Steele—follow me and Mr. Tom. The trail ain’t good, but I reckon you won’t tip over your crowd if you’re careful.”

The girls on the buckboard screamed at that; But it was too late to expostulate—or back out from going on the trip. The half-wild ponies were off and Bob had all he could do to hold them. Old Bill Hicks and his punchers had swept away into the starlit night some minutes before and were now out of both sight and hearing. As the party of young folk got out of the coulie, riding over the ridge, they saw a dull glow far down on the western horizon.

“The fire!” cried Ruth, pointing.

“That’s what it is,” responded Jane Ann, excitedly. “Come on!”

She raced ahead and Tom spurred his mount after her. Directly in their wake lurched the buckboard, with the excited Bob snapping the long-lashed whip over the ponies’ backs. The vehicle pitched and jerked, and traveled sometimes on as few as two wheels; the girls were jounced about unmercifully, and The Fox and Helen squealed.
