Paul declared that they were not, however, and wanted to go on with the rest of the film, which included the showing of other, but less dangerous, inventions. "No, you take the rest of the day off," directed the manager. "There is no great rush about this." The crowd pressed curiously about Paul and the others of the moving picture company, and, as Ruth and Alice were getting hemmed in, Mr. Pertell called a taxicab and sent them home in it. "Report at the studio to-morrow," he called. "Did you have any more trouble with that spy?" asked Alice, as the vehicle moved away. "No," he answered. "I guess they'll quit, now that they know I have found them out." The next day Paul finished with his invention-film, being required to do a number of "funny stunts," such as shaving with a new safety razor that did anything but what it was intended for; trying a new wardrobe trunk, that unexpectedly closed up with him inside of it, and such things as that. Some of the inventions were real, and others were "faked" for the occasion, to make a "comic" film. But nothing as risky as the rope escape was tried, though probably had Paul been required to go through an equally hazardous feat he would not have balked. Moving picture actors often take very big chances, and the public, looking at the finished film, little realize it. "I have something for you to-day I think you'll like," said Mr. Pertell to Ruth and Alice, as they reported at the studio. "I hope it is outdoor stuff," ventured Alice. "It is just glorious to-day!" Moving picture work is referred to as "stuff." Thus scenes at a river or lake are "water stuff," and if a play should take place in a desert the action would be termed "desert stuff," and so on. "Well, I'm sorry, but only part of it, and a very little at that, is outdoor stuff," replied Mr. Pertell. "The action of this play takes place in a shirt waist factory. And I've got the use of a real factory where you two girls will pose and go through the 'business.' You're to be shirt waist operators, and I'll explain the story to you later." "I can't sew very well," confessed Alice, "and I never made but one shirt waist in my life--I couldn't wear it after it was done," she added. "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."
