"How did I know it belonged to you?" whined Glutts, much crestfallen over the sudden turn affairs had taken. "We found the stuff on the rocks." "You can't play the innocent that way," broke in Randy. "You and Gabe Werner must have followed us to this island. Gee!" he added quickly, "where is Werner?" "Jack went after him," answered Fred; "and so did Andy and Spouter." "We didn't follow you at all," answered Bill Glutts. "We have as much right on this island as anybody. We ran across that lunch by accident. We didn't know that anybody was coming back to get it," he added lamely. In the meanwhile Jack was hurrying after Gabe Werner, and, strange as it may seem, Ruth followed close behind him, at the same time calling to the others for help. She remembered the anonymous note which had been delivered, and she was afraid that Gabe Werner might try to do the young captain serious injury. Gabe Werner was legging it among the trees. He was trying to reach the shore of Bluebell Island, but became confused among the rocks and bushes and presently had to swing around in something of a semicircle, and this soon brought him face to face with Ruth. "Oh!" cried the girl, in increased alarm. "Don't you dare touch me, Gabe Werner! Don't you dare!" "Get out of my way!" roared the bully, and then, as he heard Jack crashing through the brushwood directly behind him, he brushed Ruth rudely to one side. "Jack! Jack! Here he is!" the girl screamed. The young captain did not need to be told this, for he saw Gabe Werner just ahead of him. He made a flying leap forward, and was barely able to catch Werner by the tail of his coat. "You can't get away! You might as well give it up," he said, and as the bully kicked out savagely, he caught Werner by the foot and sent him headlong. "Oh, Jack! Jack! Do be careful!" cried Ruth in increasing alarm, and then she set up a call for assistance. "I'm not afraid of Gabe Werner, and he knows it," answered the young captain. "I'll fix you for this!" roared Werner. "I owe you a lot for the way you've been treating me." And with these words he scrambled to his feet and aimed a blow at Jack's face. The young captain moved to one side so that the blow struck him on the shoulder. He came back quickly with one on Werner's right ear, and followed this up with another on the bully's nose, which made that organ bleed profusely. By this time there was more noise in the under-brush, and Andy and Spouter could be heard calling. "This way! This way!" answered Ruth. While she was calling, and while Andy and Spouter were doing their best to brush aside some thorny bushes which held them back, the struggle between Jack and Werner continued. The bully landed on Jack's shoulder again and then on his chest, and in return received a crack on the chin which all but keeled him over.
