"O, that's all very well," said Clive, "but think how certain you were about the driver--" He was interrupted by the sound of galloping horses and rolling wheels. The sound came from behind. At once they all turned their heads. Emerging from behind a torn in the road, they saw two horses galloping at full speed, and drawing a carriage. The driver was whipping the horses furiously, and calling and shouting. The carriage was empty. In a moment they recognized the truth. It was their carriage and their driver. They all stood still, and looked in surprise, and the carriage rolled swiftly up. The driver at once stopped the horses, and jumped to the ground. Then, coming to the boys, he burst forth into a strain of the most profuse and vehement apologies. He implored them to forgive him, and began to explain the cause of his absence from the place where they had left him. It seems that he found this place an inconvenient one, and had driven across the fields for about half, a mile, to some trees. Here he had taken his horses out, and allowed them to feed. He himself lay down in the carriage, and took a _siesta_. He overslept himself. On awaking, he was horrified to find how much time had passed, and at once proceeded to search for the horses. But during his sleep they had both wandered off, and could not be found until after a long search. When at length he was ready, and had driven back, he found to his horror that they were not there. Thinking that they were still among the ruins, he had gone over the whole place, which took up still more time. At last he saw that they must have left. He at once drove off. Knowing that they were on foot, he expected every minute to catch sight of them. He drove on for miles without seeing any trace of them, and at length came to the conclusion that they had, perhaps, found the carriage of some other visitors, and had obtained seats in that. He knew that they must have gone, and could only account in that way for their rapid progress. This explanation of the driver was perfectly satisfactory to them all, and their joy at getting the carriage again was so great that they excused his unfortunate slumbers. The driver also, on his part, had now forgotten all about his sulks, and was the same genial and companionable soul as before. On learning about Bob's mishap, he at once assured them that the donkey must have run along the road, and that they would undoubtedly soon catch up with him. So the whole party got into the carriage, the driver whipped up the horses, and away they went towards Salerno. Mile after mile was traversed. Still there were no signs of Bob, "Something's happened," said Clive. "He's been carried to the mountains," said David. "It's the brigands!" groaned Uncle Moses. "O, it's all right," said Frank, confidently. "That donkey's a regular race-horse. We'll find him at Salerno." At length they reached Salerno. They drove up to the hotel. No signs of Bob!
