The train stopped, and brakemen were now running through the cars in search of the trouble. Passengers had broken the tool boxes and were fighting the spreading flames with hand grenades and portable extinguishers. Fainting women called for attention--among these being Lily's mother. Tavia was now lifted to a seat, and Dorothy had called into her ears that the baby was safe--she was not even scratched! But Tavia was not so fortunate, for an ugly red mark showed where the tongue of fire scorched her, and her hair-- One side was entirely burned off! Dorothy's heart sank as she noticed the loss, but it was nothing, of course, compared to what might have happened to the baby. The excitement in the rear of the car had, by this time subsided somewhat, showing that the flames were extinguished. Lily, safe and uninjured, sat in her mother's lap--no danger of her getting away again evidently. Among the passengers was a doctor who offered his services to Tavia. The burns were slight, he declared but there was danger of shock, and the loss of her beautiful hair was to be regretted. Tavia tried to laugh to assure Dorothy she was all right, and then she insisted upon talking about the accident. "The lamp did not explode," she declared. "The fire came from the other end of the room." The trainmen listened anxiously to this report. They were obliged to make a most careful investigation, and Tavia was very willing to help them. Professional looking men crowded around--one who introduced himself to the doctor as a well known lawyer of Rochester called Dorothy aside and offered to look out for the interests of the injured girl. "Whatever you think best," Dorothy said, "I have never had any experience with law. But if you think we should take account of it at all I should be most grateful for your help." Then Tavia was taken into a private compartment, and there, with Dorothy encouraging her, and the lawyer and doctor listening, she told the story of the accident. "I had lighted the alcohol lamp," she declared, "but I am positive that did not explode. The flash came from behind us--the other end of the room. Then the door would not open--oh how dreadful that was!" For a moment Tavia covered her eyes, then she resumed: "I heard Dorothy's voice and that seemed to keep me from falling in the smoke. At last the door opened and that's all I know." "Now, you just rest here," the doctor advised, "while Mr. French and I do some outside investigating." Then it was that the important clew was discovered, for at the very door of the little room, where the fire had raged, was found a piece of glass with a label! Gasoline! "She was right," declared the lawyer, taking possession of the tell-tale piece of bottle, the railroad men would have been so glad to have seen first, "this tells the story. A bottle of gasoline exploded."
