While Snake was frying the bacon and making the coffee, some of the others cast about the camp in a circle, seeking some clew to the midnight visitor. But nothing could be found that shed any light on the mystery. It was evident that the man, whoever he was, had ridden to the camp, had picketed his horse out some distance and then had sneaked in among the prostrate, sleeping figures. Evidently his object was merely to leave the warning, and not to rob or commit some more serious crime. And his touching the foot of Dick was an accident. Then, seeing he had caused an alarm, the man slipped away, dropping his note.

Puzzle their heads as they did, none of the six could recall any one, either among their friends or enemies, whose initials were S.T. and Dick's suggestion, that the symbols of a name were only assumed, seemed to be generally accepted.

Breakfast was eaten, camp was broken and once more, after another casual casting about for possible clews to the intruder, the cavalcade was under way. But one more night separated them from the vicinity of Death Valley and the new ranch.

"And the sooner we can get there and begin checking up on some of the things we've heard the better I'll like it," remarked Bud.

"I guess we all will," echoed Nort.

"I only hope we'll find something tangible, and not a lot more mysteries," spoke Dick.

"It'll probably turn out to be poisoned springs or bad water," suggested Yellin' Kid. "That's the most reasonable explanation."

"Um!" was all Billee Dobb would reply to that.

They made rather good time that day, as the trail was now downward for they had passed the range of low hills outside of the valley. And when night came, and they were once more camped out, they knew that the following day would see them at Dot and Dash ranch.

"What about standing guard to-night?" asked Bud of his cousins when camp was established and a good supper had been eaten.
