But the public saw none of this when the film was exhibited, for only motion was shown, the various sections of the celluloid being joined together in such a way as to preserve the continuity.

"Now ready for the big scene," called Mr. Pertell, after one of these stops. "It's going very well."

Ruth and Alice who, with Paul, were in the regular auto, had shown or "registered" all sorts of emotions during the chase. Sometimes the pursuing auto would be almost up to the one in front, and again it would lag far behind, in order to conform to the requirements of the script, or the story of the film play.

"You will run your car up to here," said Mr. Pertell to the chauffeur of the machine containing Ruth, Alice and Paul. "Then you will stop, and the substitution will be made. Come on with as much speed as is safe, right to this mark," and he indicated a stone in the highway.

"And be sure you do stop!" exclaimed Paul, with a short laugh. "That's rather too near the edge of the cliff to suit me."

"I know it is," agreed Mr. Pertell, "It has to be. I only want a few feet of the film showing the actual smash. If it runs too long the public may see the dummies too plainly. I want this as real an accident as it's possible to have it."

"It seems like tempting Providence," murmured Ruth.

"Don't get 'Sneedified'," was the retort of Alice.

Russ had set up his camera to get views of the auto coming down the steep slope, and now, at his signal that all was in readiness, the chauffeur of the car started it again.

"Business! Business!" called Mr. Pertell to the moving picture girls and Paul, meaning that they were to use the proper gestures, and register the desired emotions to coincide with the play.
