“Don’t say anything for a while,” Roy whispered. “Not till we get a way out.” Mohammed Ali Ben Suliman sat upright, his long robe trailing over the edge of the wagon. Stamboul walked on, and when the mystic had passed over a little hill, out of sight of the ranch, he turned. “Looks kind of like rain, doesn’t it?” he called, every trace of his accent gone. Teddy started. Roy smiled. CHAPTER XVI THE START OF THE ROUND-UP “Sure does,” Roy answered Mohammed Ali Ben Suliman’s question casually. He saw that Teddy was about to speak, and silenced him with a glance. Both boys urged their ponies forward until they were close to the man in the buckboard. “Mind telling us your real name?” Roy asked pleasantly. “Who, me? Not at all.” The man drew his fez from his head, reached into his robes, and filled and lit a pipe before answering. “I can’t take these robes off,” he apologized. “It’d scare the donkey if he turned around. My name is Benjamin Sullivan. I’m a professor of psychology in the university of Middleton. That, in case you don’t know it, which you don’t, is what is known as a jerk-water college.” “A professor of psychology!” Teddy exclaimed. “Then you’re not--” “Hardly,” and the professor grinned. “This is what I do every vacation. It--er--adds to my income--” he coughed--“and also to my knowledge. It’s wonderful practice for a psychologist. Say, would you mind telling me how you got on to me?” he asked Roy. “I knew you realized I wasn’t what I pretended to be when you were watching me at the table.” “Well, there wasn’t any psychology about that,” Roy chuckled. “When you drew your robes back to get the flower pot I saw the pipe sticking out of your top pocket. Never heard of an East Indian yet who smoked a briar.” “You saw that, did you? I’ll have to remember to put it in my trousers’ pocket after this. Get along there, Stamboul. Then you rode out with me just to let me know I hadn’t gotten away with anything?” “Not altogether,” Roy answered seriously. “You mentioned something about our enemies. Was that a stab in the dark, or did you really know what you were talking about?” Professor Sullivan puffed silently for a moment. “Well, I’ll tell you,” he said finally. “Last night I was traveling through a small town about ten miles from here. Let’s see--Bed Rock, or something like that.” “Red Rock!” Teddy exclaimed eagerly.
