"What is it?" asked Gardley, awed with the awful sorrow in the strong man's attitude.

"My poor baby!" groaned the father. "My poor little baby girl! I've always been afraid of that fatal gift of hers. Gardley, she could copy any handwriting in the world perfectly. She could write my name so it could not be told from my own signature. She's evidently written that letter. Why, I don't know, unless she wanted to get Miss Earle out of the way so it would be easier for her to carry out her plans."

"It can't be!" said Gardley, shaking his head. "I can't see what her object would be. Besides, where would she find the Indians? Mrs. Tanner saw the Indians. They came to the school after her with the letter, and waited for her. Mrs. Tanner saw them ride off together."

"There were a couple of strange Indians here yesterday, begging something to eat," said Rogers, settling down on a chair and resting his head against the desk as if he had suddenly lost the strength to stand.

"This won't do!" said Gardley. "We've got to get down to the telegraph-office, you and I. Now try to brace up. Are the horses ready? Then we'll go right away."

"You better question the servants about those Indians first," said Rogers; and Gardley, as he hurried down the stairs, heard groan after groan from Rosa's room, where her father lingered in agony.

Gardley got all the information he could about the Indians, and then the two men started away on a gallop to the station. As they passed the Tanner house Gardley drew rein to call to Bud, who hurried out joyfully to greet his friend, his face lighting with pleasure.

"Bill, get on your horse in double-quick time and beat it out to camp for me, will you?" said Gardley, as he reached down and gripped Bud's rough young paw. "Tell Jasper Kemp to come back with you and meet me at the station as quick as he can. Tell him to have the men where he can signal them. We may have to hustle out on a long hunt; and, Bill, keep your head steady and get back yourself right away. Perhaps I'll want you to help me. I'm a little anxious about Miss Earle, but you needn't tell anybody that but old Jasper. Tell him to hurry for all he's worth."

Bud, with his eyes large with loyalty and trouble, nodded understandingly, returned the grip of the young man's hand with a clumsy squeeze, and sprang away to get his horse and do Gardley's bidding. Gardley knew he would ride as for his life, now that he knew Margaret's safety was at stake.
