THE SIGNAL
"What's the matter?" cried Dick, hastening from the tent where he had been making a new loop on his lariat, in preparation for practicing some of the stunts worked by Four Eyes.
"Have you discovered something from the tower?" asked Nort.
"Yes, I've discovered that the tower isn't any good!" exclaimed Bud with emphasis. "Oh, it isn't your fault, Dick," he went on, as he saw that his cousin looked a bit crestfallen. "The tower is all right."
"Then you saw some rustlers from it?" asked Nort.
"No, that's the trouble," said Bud, ruefully. "We didn't see them but they were here all right—last night. Tell us about it, Billee," he requested.
"Well, there isn't an awful lot to tell," said the veteran cow puncher. "I was just prospectin' around, over on that new growth of Johnson grass, like you told me to, an' I saw where a steer had been killed, an' they had eat most of it, too, by th' signs."
