"You don't really have to sew," explained Mr. Pertell. "It is all machine work, anyhow. You and Ruth will sit at the machines in the factory with the other girls. Miss Pennington and Miss Dixon are also to be operators, but you two are the main characters. The machines work by a small electric motor, and all you have to do is to push some cloth along under the needle. You can do that."

"I guess so," agreed Alice.

"The forewoman will rehearse you a bit," Mr. Pertell went on. "The scene at the machines only takes a few moments—just a little strip of film. Then the scene changes to another part of the factory. I think it will make a good film. The story is called 'The Eye of a Needle.' It's really quite clever and by a new writer. I think it will make a hit."

Ruth and Alice, as well as the others, were told more in detail what action the play required, and the next day they were ready for their parts. They went to the factory accompanied by the two former vaudeville actresses, and by Russ and Paul. The latter was to take the part of one of the male employees of the concern.

Ruth and Alice found themselves in a room filled with sewing machines, at which sat girls and women busily engaged in stitching on shirt waists. There was the hum of the small electric motors that operated the machines, and the click and hum of the machines themselves.

A murmur ran around the room on the entrance of the players, but the operators had been told what to expect and what to do. They were to be in the pictures, too.

Ruth and Alice, with Miss Pennington and Miss Dixon, were given machines close to the camera, as they were the principal characters, and interest centered in them.

"Just guide the cloth through under the needle," the forewoman explained, as she started the motors on the girls' machines.

"Ready!" called Mr. Pertell to Russ, who stood beside the camera. The action of the play began, as Russ clicked away at the handle of his machine.

Suddenly a girl screamed.
