So the last stone was thrown, and as the _Pot Luck_ sailed out upon the broad reach below the city, where the two mighty rivers have their confluence, Frank and his chums could get their breath again, and survey the damages. Two windows in the cabin had been broken, and there were a score of rocks and pieces of iron lying on the deck; besides numerous dents in the woodwork; but on the whole, they might feel they had escaped in pretty fair luck. Ossie was recovering his breath, and also his courage. He seemed to feel queerly about having been rescued from danger by the very boys whom he had been trying to injure for so long. Frank thought the opportunity for healing the breach between them was a good one, and after they had managed to push the houseboat in toward the shore, below the mouth of the Ohio, a hard task that took much time, he approached his rival, with a pleasant smile on his face. “That was a pretty ugly experience, Ossie,” he remarked. “How did it happen you got caught in that mob, and were taken for a strike-breaker?” “Why, you see, we had anchored down below here, when I remembered that I ought to have done an important errand for my father in Cairo,” the other explained. “As our engine was out of commission again, I hired a man to row me up to the city. He took more than half the morning to do it, too, and was to bring me back again in the afternoon. I heard about the rioting, and thought I’d like to see something of it on my way down to the river to find my boatman. Then, almost before I knew what was happening, it broke out all around me, and I was caught up in a pack of blacks retreating before an attack of another mob. I tried to get away, but you saw what happened. Whew! I wouldn’t like to repeat that experience. And look, there’s the _Lounger_ right now! Could you hold up, and put me aboard?” Frank was quite willing. They had one passenger aboard now, which was more than the law, as laid down by Uncle Felix, allowed; and they certainly did not care for another. He believed that if Oswald had listened to his better nature he would have wiped the slate clean then and there, after finding himself indebted so heavily to his supposed rival; and become friends from that hour with the crew of the _Pot Luck_. But there were his three chums lining the side of the _Lounger_, and evidently in a great state of mind to see Ossie coming back aboard the other houseboat, which certainly showed signs of hard usage. The anchor was allowed to drop overboard, and Frank himself took the captain of the _Lounger_ across the few fathoms of water separating the two houseboats. Oswald was greeted by a noisy outcry as he climbed up on deck. The three who stood there, fearing that there was some danger that the bad feeling of the past would be crossed out, scowled at the crew of the _Pot Luck_, and even gave utterance to more or less contemptuous remarks concerning the rival craft.
