The youths decided to see the old section of the city, as they had heard from Dr. Kirshner that many points of interest were to be found there. It was but a few minutes' walk to their objective, and they turned their eyes about. As they were passing a café, Bob motioned for his friend to look inside. A gray-haired, shriveled old man in torn clothing was strumming a guitar and walking from one end of the café to another, holding out a hand for money. But no one seemed inclined to give him any. Evidently this was a common occurrence, for the people paid little or no attention to the old beggar. "I've half a mind to give him a break," started Bob, but Joe pulled him back. "If we want to see any of this town we'll have to be at it," Joe said, leading the way down the street. The narrow ways were lined with shops and bazaars, offering the shopper a wide variety of commodities. "But most of the things they sell you don't want," smiled Bob, glancing at a counter laden with coarse native food. The youths noticed that certain streets were devoted to the selling of certain products. For instance, one avenue was lined with shops displaying brassware. "It ought to be easy to find what you want," grinned Joe. "Just walk down one street and you will have a large choice of the same thing." The boys spent nearly a half-hour in the native quarter. Finally Bob suggested that they get back to the hotel, and his friend was also in favor. In a short time they were back in the hostelry and proceeded to go to their rooms. But they were scarcely at the doors when the sound of footsteps came to their ears. The next moment Dr. Kirshner came into view. "Hello," greeted Bob, and then his jaw dropped. That something was wrong was evidenced by the frown that was on the archæologist's face. His usual smile was absent. "There's been a wreck," he said in an anxious voice. "The train has been wrecked. I guess we can't get to Wargla so soon after all." CHAPTER IV Lured to Danger Bob and Joe gasped in astonishment. "The train wrecked!" muttered Bob and then started. "What caused it?" "I imagine you're thinking the same as I," the archæologist said quietly. "That those thieves were responsible for it to prevent us from getting to Wargla at once." Joe's face glowed with anger. "The dirty beggars!" he cried. "Was anyone hurt?" "No. It happened that no one was. But the locomotive was derailed and lodged in a ravine, and the work of getting it back on the track and repairing it won't start any too soon in this country. It may be two or three days before order will be restored. It looks like those robbers have won out after all." They walked on into the room, where they were met by the boys' fathers and Fekmah. "Is there anything wrong?" asked Mr. Holton, as he noticed the sober faces of his friends. The situation was explained, and the men frowned. Fekmah especially was agitated.
