175 feet long.

The scene opens in a schoolhouse. The children are busy studying their lessons, the teacher making demonstrations on the blackboard. Mephisto suddenly appears coming up through a trap door in the floor, and goes around whispering to all the children. The figures made by the teacher on the blackboard suddenly and mysteriously come together, forming a great picture of a church. The dunce is accused of being the instigator of the mystery and is called out in the centre of the floor, the dunce cap placed upon his head and he is fogged by the schoolteacher. The devil appears ou the teachers desk, jumping around in a fantastic manner. The schoolteacher leaves the room and pandemonium reins, the children dancing around and making great noise. When the schoolteacher suddenly appears, each scholar flies back to his seat and all is quiet. The globe is then brought in for the children's instructions in geography. When the schoolteacher's back is turned upon the globe, it is suddenly changed into a very curious looking human being with a funny head, which rolls around, making fantastic grimaces and facial expressions. The head and body are then changed into a hideous looking object, half man and half dragon. The teacher then rushes to his desk for his rule and the devil shuts the desk cover down on his head, cutting it off. The teacher then walks about the schoolroom headless. His bead suddenly flies back on his body and he rushes from the schoolhouse in great fear. One of the finest mystical pictures ever attempted.
