"Something is wrong!" The senator's son answered the summons on a run, and the three girls trailed behind him.

The newcomers to Star Ranch did not know what to say, but Belle uttered a cry of dismay: "Horse-thieves!" "Oh, Belle, do you really think somebody has stolen the horses ?" queried Laura, while Jessie turned very pale.
"Yes, I do," was the blunt response.

"That is, if they were tied properly." "Yes, they were well tied--I saw to that myself," said Dave.
"I know mine was tied fast, and so was Laura's," added the senator's son.
"And I put a double knot in the rope to Belle's and mine," came from Phil.
"One thing is sure," said Laura.

"They couldn't very well all break away at once." "I am sure it is the work of horse-thieves," responded Belle.

"Papa has been afraid they might come back." "But how did they know about our horses being here ?" asked Phil.
"They must have watched us and seen us ride away from the ranch, and then they followed, and took the horses while we were up the river." "If only we could follow them, and get the horses back!" said the senator's son, with a sigh.
"They must be worth a lot of money," murmured Jessie.
