"What's the matter ?" "Those girls are running for all they are worth!" said Dick.
"A bull is after them!" came from Tom.

"My stars! but he seems to mean business!" Tom was right, Helen and Alice Staton were running along the highway at all the speed they could command.

Behind them, less than fifty feet distant, was the enraged black bull, bent on doing all the mischief possible.
"Those girls will be hurt!" said Dick, running forward.
"Can't we do something ?" asked Sam.
"We can try," said Tom.

"Get a rock, or something," and he picked up a sharp stone which lay handy.

Sam did likewise.
By this time the twins were almost upon the boys.
"Chase the bull away!" panted Helen, who was ready to drop from exhaustion.
"Yes! yes!" gasped Alice.
