They were about to depart when Rush pricked up his ears and gave a peculiar whinny.
"Hush! What does that mean?" Paul asked in quick alarm.
"Draw behind the brush and see," replied Chet, cautiously. "Those horse thieves may be still in the vicinity."
"Oh, they would not remain here," said Paul.
Yet he followed his brother behind the brush. They tried to make Rush come, too, but for once the animal would not obey.
"Come, Rush, come," whispered Chet. "Why he never acted this way before."
"The cyclone upset his mind, I reckon," said Paul, with a faint show of humor. "Make him come."
But the more Chet tried the more obstinate did the animal become. Finally he broke away altogether and ran off, kicking up his heels behind him.
"Well, I never!" gasped Chet.
"Quick, after him! I believe he means to run away!" cried Paul.
"Rush run away!" said Chet reproachfully. It hurt him a good deal to have Paul speak in that fashion of the horse he so loved.
