There was good cause for our hero's anger. On the rocks lay the overturned berry kettles, the berries scattered in all directions and many of them crushed under foot. "And look at the boat!" gasped Jack, turning to inspect the craft. The rowboat was partly filled with water and on the seats and in the bottom a quantity of mud had been thrown. The oars were sticking in a mud bank close by. "Does she leak?" asked our hero, with concern. "I'll have to find out." It was soon discovered that the craft was intact, and then they set to work to clean up the muss. This was no easy job, and the boys perspired freely, for the day was a warm one. Then Randy looked over the scattered berries. "About one-third of them are fit to take along," he said. "The others are crushed and dirty." "I'll tell you what I am going to do," said Jack, stoutly. "I am going to make Bob Bangs pay for dirtying my boat, and he can pay for the lost berries, too." "But how can we prove he is guilty?" "We'll make him own up to it. Nobody else would play such a mean trick." The two boys were in no happy frame of mind as they rowed back to Riverport. They suspected that Bob Bangs would keep out of their sight, but just as they were landing they caught sight of him peering at them from behind a dock building. "There he is!" cried Jack. "After him, Randy!" "Right you are!" answered our hero, and ran after Bob Bangs with might and main. Randy was a good sprinter and although the rich youth tried to get away he was soon brought to a halt. "Let go of me!" he roared, as Randy caught him by the collar. "Not just yet, Bob Bangs!" returned Randy. "A fine trick you played this afternoon." "I didn't play any trick!" "Yes, you did." "I didn't! Let me go!" And now Bob Bangs did his best to get away. He saw that Randy and Jack were thoroughly angry and was afraid he was in for a drubbing--or worse. He gave a jerk and then started to run. Randy put out his foot and the big youth went sprawling full length, his face violently striking the ground. CHAPTER V THE RESULT OF A QUARREL If any boy was ever humiliated it was Bob Bangs. His face and hands were covered with dust and so was his elegant suit of clothing, while the skin was cut on the side of his nose. "Now, see what you have done!" he spluttered, gazing ruefully at himself. "My suit is just about ruined!" "And it serves you right, Bob Bangs," came warmly from Jack. "That is what you get for trying to run away," added our hero. "I'll have the law on you, Randy Thompson!" "Maybe I'll have the law on you, Bob Bangs!" "You had no right to throw me down in that fashion." "Then why did you start to run away?" "Because I didn't want to stay here--and you had no right to stop me." "We wanted to know about this berry affair," said Jack. "And about the dirty boat." "I don't know what you are talking about," answered the big boy, but his face showed his concern. "You put mud in my boat and spilled our berries."
