The young ladies of the household were waiting, dressed in short skirts and wearing broad-brimmed straw hats. To the boys they were most attractive. Their fresh young faces lighted with anticipation of the day's pleasure as, assisted by the Pony Riders, they swung into their saddles. It fell to Tad Butler to ride beside Miss Brayton.

"We had a stampede at the camp last night," he told her after they had headed off to the east for the Springs, which was to be their first objective point.

"Yes; so uncle told me. I'm sorry. Did you lose any stock?"

"I believe not, unless it was some of the new ponies. I did not think to ask."

"At what time did the trouble occur?" she asked absently.

"I think it was shortly after you left us at dinner, last night," answered Tad, in a matter-of-fact tone. "It was, perhaps, half an hour after that when your uncle told us."

Miss Brayton flushed painfully, and quickly changed the subject. Tad noticed her confusion and marveled at it.

Arriving at the Springs, which proved to be a group of rocks rising out of the plain, and from which several springs of pure sparkling water bubbled, all dismounted and drank of the refreshing fluid. After a few moments spent in chatting, they remounted their ponies and set off for the adobe church, the real object of the day's journey.

Reaching the historic place, they tethered their ponies among the mesquite bushes in the rear of it, after which all entered through a crumbling doorway. The interior, they found, was in an excellent state of preservation.

Many surprising little alcoves and odd, cell-like rooms were distributed all through the church. It was dark and cool in there. Chunky shivered, and said he didn't wonder people said there were spooks there.
