This was the company, with others whom you will meet from time to time, in whose fortunes Ruth and Alice DeVere had cast their lots.

After the girls' first introduction to the camera they went to Oak Farm where a series of pictures were taken, and, incidentally, a mystery was cleared up. Getting snowbound was another experience for our friends, but they forgot the cruelties of Winter in the happy days under the palms. And they had only recently come back from Rocky Ranch, where a number of Western dramas had been filmed, when the little scene of our opening chapter took place.

Those of you who have read the previous books of this series do not need to be told much about moving pictures. And even those who select this volume as their first venture in becoming acquainted with our heroines must well know how the film pictures look from the front of the screen.

To the uninitiated I might say that in making picture plays a company, somewhat like a regular theatrical organization, is gotten together. The play is decided upon, but instead of the acts taking place before an audience they are enacted before a camera and a man who acts as director, or manager.

Some of the action takes place out of doors, amid the surroundings of nature, but most interior scenes are "filmed," or taken, in the studio, under the brilliant glare of electric lights. The pictures are taken in succession on a narrow strip of celluloid film, of the same nature as those in any camera. The strips are of a standard length of one thousand feet, though some plays may "split," and take only half a "reel" while others will fill several.

When the film has been exposed, it is developed in a dark tank, and from that one "master" film, any number of "positives" can be made for use in the projecting machines. Doubtless you know that the same machine which takes the pictures does not show them on the screen.

But enough of this detail.

"Was the rarebit good?" asked Alice, smiling up into her father's face, as the supper progressed.

"You may give me some more, which is the best answer in the world, my dear," he replied, smiling.

"Be careful!" Ruth warned him. "You may have dreams, Daddy!"
