"I'm glad of that. Come up to my room and tell me all about it, Dashaway. Now then, for a talk over old times," resumed the moving picture man, as they were comfortably seated in his room at the hotel. Dave parried a good many questions. He did not exactly wish to tell Mr. Alden about his business, which in the present case was also that of his employers. He managed to lead Mr. Alden to talk of his own affairs. "Oh, I've had the actors up here on a lot of marine scenarios," explained the moving picture man. "They went away only this morning. We've been picturing 'The Island Hermit of Lake Superior,' 'Iron Miners' Revenge,' 'Flight Across the Border,' and 'The Mystery of the Pineries.' Great scenery around here for fittings, you see. There are some of my key negatives on the table there, look them over." Dave examined some of the films with interest. The former kindness of Mr. Alden and his party had left a warm spot in the heart of the young aviator for anything concerning the movies. "There's some plain slides we made to catch the costumes and figures," added Mr. Alden, pointing to a rack containing about a dozen glass negatives. Dave began holding them up to the light in turn. He had inspected perhaps one half of them, when he somewhat startled the moving picture man with a sharp sudden exclamation. "Mr. Alden," he asked quite excitedly, "where did you take that slide?" CHAPTER XVIII ON DESERT ISLAND The young aviator might well ask the question he put to the moving picture man, for the negative in Dave's hand showed plainly the face and figure of Jerry Dawson. There could be no mistake. The boy who had run away with the Drifter had features strongly marked and not readily forgotten. The picture had been taken in the open street. Jerry was standing there talking to a Chinaman. "Some scene you know, Dashaway?" asked Mr. Alden. "No, somebody I know--and am very anxious to find," replied Dave. "So? Let me have a look at it." Dave handed the plate to the moving picture man, who slanted it against the light and nodded intelligently. "Oh, that?" he said. "Yes, I remember all about it." "Where did you take it, Mr. Alden?" pressed Dave. "At Anseton. There's a sort of foreign quarter there, and I was catching up some street scenes. It was the Chinaman I shot. Wanted the costume, you know." "When was that?" asked Dave. "Yesterday morning." Dave asked a score of questions. The moving picture man saw that Dave had some important motive in his inquiries. He did not ask what it was, and was patient and careful in his replies. Dave left Mr. Alden feeling that he had learned a good deal. The presence of Jerry Dawson in Anseton, and that, too, with a Chinaman, verified many of the theories of the young aviator. Dave lost no time in getting to a telegraph office, to send a dispatch that would reach Mr. Price. It told briefly of the progress of the Monarch II and of the definite clew Dave had just discovered.
