"How could I? There were none to make. You were with me when he asked me about the clock face and you heard all I said. When I left the dial in the store he was not there. I haven't seen him since. The reporter is drawing on his imagination I guess for considerable of this." "I wonder if they are going to have an investigation?" said Bart. "Let's go and see Mr. Williamson," suggested Fenn. "We can show him the article and he can tell us what to do. I think that's the best plan." The other two chums agreed to this, and, each one having purchased a paper containing the startling news, they went to the hardware store of the president of the Board of Education. Mr. Williamson was talking to some other members of the board, in his private office, when the boys entered the store. They sent word they wanted to see him, and in a little while, his visitors having gone, the president invited the chums in. "Well, boys," he began, "what can I do for you?" "This article," began Bart. "It seems to--" "I have read it," Mr. Williamson interrupted. "Do you suspect us?" demanded Bart. "That is hardly a fair question," Mr. Williamson replied. "I shall probably be called upon to preside at the investigation and I can not discuss the case in advance of the hearing. I will say this however: We believe some boy or boys blew up the tower, little thinking of the terrible danger to which he subjected the entire school and that audience. We have no direct evidence, as yet, but we expect to get some. I may add that a hearing will be held to-night, and I would like you boys to be there. I understand Ned Wilding has gone to New York." "He went this morning," replied Bart, "but he had planned to go long before this thing happened. We are going to join him Wednesday." "Indeed?" and Mr. Williamson looked a little surprised. "What time is the hearing?" asked Fenn. "At eight o'clock, in my office here." "We'll be on hand," spoke Bart. All the members of the Board of Education, the school janitor, the chief of police, a detective, the fathers of Bart and Fenn, and Frank's uncle were at the hearing. There was much testimony in an informal way, to the effect that the tower was wrecked by an explosion and not by the wind. So much was easily proved. The next thing was to discover who had done the deed. The janitor said he had seen a boy hanging around the tower just before the entertainment began, but he could not give a good description. It might fit half the boys in Darewell.
