And because these two words were just now keenly in his mind he reached for the second paper just a foot or two away and found more sentences and words. A third paper contained an exact reproduction of the letter which Mrs. Tanner had given him purporting to come from Mrs. Brownleigh to Margaret. What could it possibly mean?

In great astonishment he pulled out the other letter and compared them. They were almost identical save for a word here and there crossed out and rewritten. He stood looking mutely at the papers and then up at the window, as though an explanation might somehow be wafted down to him, not knowing what to think, his mind filled with vague alarm.

Just at that moment the servant appeared.

"Mr. Rogers says would you mind coming down to the corral. Miss Rosa has a headache, and we're keeping the house still for her to sleep. That's her window up there--" And he indicated the rose-bowered window with the fluttering curtain.

Dazed and half suspicious of something, Gardley folded the two letters together and crushed them into his pocket, wondering what he ought to do about it. The thought of it troubled him so that he only half gave attention to the business in hand; but he gave his report and handed over certain documents. He was thinking that perhaps he ought to see Miss Rosa and find out what she knew of Margaret's going and ask how she came in possession of this other letter.

"Now," said Rogers, as the matter was concluded, "I owe you some money. If you'll just step up to the house with me I'll give it to you. I'd like to settle matters up at once."

"Oh, let it go till I come again," said Gardley, impatient to be off. He wanted to get by himself and think out a solution of the two letters. He was more than uneasy about Margaret without being able to give any suitable explanation of why he should be. His main desire now was to ride to Ganado and find out if the missionaries had left home, which way they had gone, and whether they had met Margaret as planned.

"No, step right up to the house with me," insisted Rogers. "It won't take long, and I have the money in my safe."

Gardley saw that the quickest way was to please Rogers, and he did not wish to arouse any questions, because he supposed, of course, his alarm was mere foolishness. So they went together into Rogers's private office, where his desk and safe were the principal furniture, and where no servants ventured to come without orders.
