"No use letting it get on your nerves, Ralph," counseled the quiet and deliberate Walt Phelps, "worriting about it isn't going to help any."

The professor got up and paced about the old chapel, examining its walls with care. In one or two places were the remnants of old paintings, and these he examined with great interest.

"If we should ever get away from here I think that I should have some interesting discoveries to report to the Hispanic Society," he remarked amiably.

Walt Phelps nodded. The most interesting discovery he could have made at that moment would have been a door leading into the open air and a good horse standing outside it.

At noon a Mexican entered with their dinner, a similar meal to that which we have already seen served to the prisoners in the tower. Few words were spoken over the meal. Their hearts were too heavy for that. The uncertainty as to what was to be their ultimate fate was almost maddening. In addition, they had to bear the suspense of speculation over the destiny of Jack Merrill and Coyote Pete. Without the broncho buster's cheerful face and whimsical manner to cheer them the castaways were indeed in a gloomy condition.

About the middle of the afternoon they received another visit from Black Ramon. This time he brought paper and some ink. The paper was some odd sheets, half torn and very dirty, which looked as if they might have been ripped from an old blank book. The ink was a faded, rusty colored composition. Evidently, writing materials were things for which the cattle rustlers had little use.

In a few brief words, spoken with brutal incisiveness, Black Ramon informed Ralph that his offer still held good. The boy had till the next day to make up his mind to write the letter to his father, demanding the payment of the ransom. A messenger would convey it to the nearest railroad station as soon as it was written. It was for this purpose that the ink and writing materials had been brought. As Jack had feared, the Mexican was going to work upon Ralph's sensitive nature by every means in his power, and as a step toward that end he had removed Jack and the cheerful cow-puncher.

"I've half a mind to write the letter and have it over with," said Ralph, as the door closed and they were once more alone.

"Don't you do it," said Walt Phelps decisively. "I've heard of fellows in a worse scrape than ours getting out of it all right. What's the use of your alarming your folks? After all, it may only be a bluff on the part of Black Ramon."
