“They have been warned,” said O’Hara quietly. “I am not one of them now, and knowing what I do of the musket and bayonet and the lash, I lost no time in laying my suspicions before my superiors. Yes,” he said, “I was right, was I not?”

“Right? Unquestionably. Such men, until they have been proved, have no right to be free. Then that is the meaning of the extra sentries I have seen.”

“That is it, sir; but if the sentries were doubled again, I’m afraid the mistaken men would carry out their notions, unless some strong influence were brought to bear. Why don’t you try to get hold of the ringleaders, sir, and show them the madness of the attempt?”

“I will,” said Bayle quickly, and they parted; but they were not separated a hundred yards before there was a shout, and Bayle turned to see O’Hara running after him swiftly.

“What is it?” he asked.

“I’m afraid I have spoken too late, sir. I heard a shot out yonder, beyond that house where the new road is being made. A strong gang has been at work there for a fortnight past. Do you hear that?”

Two distant shots in quick succession were heard, and Christie Bayle turned pale, for the sounds came from beyond the house pointed out, and that house was Hallam’s.

“We had better go and give the alarm at the governor’s office.”

“No, no,” said Bayle. “We may be in time to help up here. Come quickly, man; run!”

It seemed madness to O’Hara; but there was a decision in Bayle’s order that did not seem to brook contradiction, and being a quick, lithe man, he ran step for step with his companion, as they made their way amongst the park-like growth of the hill-side in the direction of the spot whence the sounds had come.
