The shot had clearly been intended for Cato. Even if it were an act of mere personal revenge, it showed a confidence and security in the would-be assassin that betokened cooperation and an organized plan. He had availed himself of the thunderstorm, the flash and long reverberating roll of sound--an artifice not unknown to border ambush--to confuse discovery at the instant. Yet the attack might be only an isolated one; or it might be the beginning of a general raid upon the Syndicate's freedmen. If the former he could protect Cato from its repetition by guarding him in the office until he could be conveyed to a place of safety; if the latter, he must at once collect the negroes at their quarters, and take Cato with him. He resolved upon the latter course. The quarters were half a mile from the Dows' dwelling--which was two miles away. He sat down and wrote a few lines to Miss Dows stating that, in view of some threatened disturbances in the town, he thought it advisable to keep the negroes in their quarters, whither he was himself going. He sent her his housekeeper and the child, as they had both better remain in a place of security until he returned to town. He gave the note to Zoe, bidding her hasten by the back garden across the fields. Then he turned to Cato. “I am going with you to the quarters tonight,” he said quietly, “and you can carry your pistol back to the armory yourself.” He handed him the weapon. The negro received it gratefully, but suddenly cast a searching glance at his employer. Courtland's face, however, betrayed no change. When Zoe had gone, he continued tranquilly, “We will go by the back way through the woods.” As the negro started slightly, Courtland continued in the same even tone: “The sulphur you smelled just now, Cato, was the smoke of a gun fired at YOU from the street. I don't propose that the shot shall be repeated under the same advantages.” The negro became violently agitated. “It was dat sneakin' hound, Tom Higbee,” he said huskily. Courtland looked at him sharply. “Then there was something more than WORDS passed between him and you, Cato. What happened? Come, speak out!” “He lashed me with his whip, and I gib him one right under the yeah, and drupped him,” said Cato, recovering his courage with his anger at the recollection. “I had a right to defend myse'f, sah.” “Yes, and I hope you'll be able to do it, now,” said Courtland calmly, his face giving no sign of his conviction that Cato's fate was doomed by that single retaliating blow, “but you'll be safer at the quarters.” He passed into his bedroom, took a revolver from his bedhead and a derringer from the drawer, both of which he quickly slipped beneath his buttoned coat, and returned.
