"I saw it come shooting in from out there," and Nort waved his hand toward the darkness.

"I felt it!" grimly declared Dick. "I just managed to slip it off in time."

"You were lucky," commented Chot. "Let's see who it was," he added. "Couldn't have been any of our lads," he said in a low voice. "I've known 'em to do such tricks, but not at a time like this. Might have been some fresh puncher from Double Z, but if it was——"

"Come on!" interrupted Dirk, satisfied from a glance that no harm had befallen Dick. Dirk wheeled his horse and rode off into the darkness, in the direction where the end of the lariat had disappeared, when the unseen thrower had pulled it to him after Dick's escape.

The two cowboys, who had been on the far side of the herd, had ridden hurriedly in on hearing the cries of the startled boys. And now they rushed off in the darkness, trying to find out who it was that had displayed such evil intentions.

For it was a desperate thing to do. A little higher up and the rope would have encircled Dick's neck, and it would have taken only a short time of pulling him across the ground to have choked him. He, himself, did not realize his danger until later.

For a few moments, after the arrival of Dirk and Chot from the far side of the resting herd, and their subsequent dash off into the darkness, Bud, Nort and Dick did nothing. They stood there around the greasewood fire, trying to understand clearly what had happened.

Then, from the herd of cattle came unmistakable signs of some disturbance. There were snorts and bellows, the mooing of cows and the stamping of hoofs. At the same time, from the far side, whence Dirk and Chot had ridden in, there came the murmur of voices.

"Rustlers!" cried Bud, understanding at once what it all meant now.
"Dirk! Chot! Come on back! The rustlers are here! It's a trick!
Come on back!"

"Rustlers!" exclaimed Nort.
