Paul paused but for a moment, and then he jumped from the sill, and out away from the building. The coil of rope in the metal case had been swung out from the side of the structure on an arm, so as to enable Paul to clear the lower window ledges. For the first few feet he went down like a shot, and for one horrible moment he felt that something had gone wrong. In fact the crowd did also, for there was a hoarse shout of alarm. "Oh!" gasped Ruth, faintly. "I--I----" began Alice, as she, too, turned aside her head. Then someone yelled: "It's all right!" Alice looked then. She saw Paul descending as the rope payed out. He was coming down gradually. "That will make a good film," commented Russ to Mr. Pertell, for the manager had come to witness the fire escape scene. "Indeed it will." Paul came down several stories, and the success of the apparatus seemed assured when, at about the fourth story from the ground, something suddenly went wrong. Once more the young actor shot downward and this time it seemed that he would be seriously injured. Russ felt that he must rush forward to save his friend, but he had an inborn instinct to stick to his camera--an instinct that probably every moving picture operator has, even though he does violence to his own feelings. "He'll be hurt!" several in the crowd cried. Ruth and Alice both turned aside their heads again, but there was no need for alarm. For the firemen, at the word of command from their captain, had rushed forward with the life net. They were standing only a few feet away from where Paul dangled in the air, but even at that they were only just in time. Paul fell into it heavily, for the mechanism depended on to check the speed at which the rope payed out, did not work. But the firemen knew just how to handle a situation of that sort, and they held firmly to the net. It sagged under the impact of Paul's body, but he bounded upward again in an instant, and then was helped out of the net and to his feet. "Mighty lucky you fellows were here," observed the young actor, as the cheers of the crowd died down. "I was afraid something like that might happen," spoke the fire captain. "I've seen too many accidents with these patent escapes to take any chances. Now there's another inventor who will have to make quite a few changes in his apparatus." The man who had patented the fire escape had been in a frenzy of fear when he saw Paul slipping, and, now that he knew the young actor was safe, he began to explain how something unforeseen had occurred, and that it would never happen again. "Did you get that, Russ?" the manager wanted to know, for he thought the operator, in his anxiety over Paul, might have forgotten to turn the handle of the machine. "Every move," was the reassuring answer. "It will make a dandy film. But I'm mighty glad it turned out as it did." "So am I," said the manager. "I guess that will be about all for Paul to-day. His nerves must be on edge."
