The story of the photo-play was gripping in its intensity, and since Mr. Werner had clearly explained the lesson it conveyed, they followed the plot with rapt attention. In the last scene their entrance and exit was transitory, but they were obliged to admit that their features were really expressive of fear. The next instant the wall fell, burying its victims, and this rather bewildered them when they remembered that fully half an hour had elapsed while the dummies were being placed in position, the real people removed from danger and preparations made to topple over the wall from the inside of the building. But the camera had been inactive during that period and so cleverly had the parts of the picture been united that no pause whatever was observable to the spectators.
