"It is the correspondence which worries me most," he said. "We haven't had enough of that kind of work, so far, to justify us hiring a stenographer, but some days the mail is so heavy that it keeps me pounding on the typewriter an hour or more. Now, Mary, if you had only added shorthand to your many accomplishments, there'd be a fine chance for you to help hold the fort till Bailey gets well." "I can help do it, anyhow," she declared promptly. "I know how business letters ought to sound--'Yours of recent date' and 'enclosed herewith please find' and all that sort of thing. I can scratch off in pencil a sort of outline of what you want said, and then take my time copying it on the machine." Past experience had taught the family that whenever Mary attempted anything with the eagerness with which she proposed this plan, she always carried it through triumphantly, and Jack's face showed his relief as he promptly accepted her offer. "No use for you to come down this afternoon," he said. "I'll be too busy looking after other things to give any time to letters." "But I can be making the acquaintance of the machine," answered Mary. "Madam Chartley's stenographer learned to run hers simply by studying the book of instructions. And if it won't bother you to hear me clicking away I'll put in the whole afternoon practising." [Illustration: "SEVERAL TIMES SHE STOPPED JACK IN PASSING TO ASK HIM A QUESTION."] So when Jack went back to the office, Mary went with him, happy and excited over this unexpected entrance into the world of Business. "Who knows but what this may be a stepping-stone into a successful career?" she exclaimed. "Why didn't I think of applying to you for a position in the very beginning? It would have saved a world of worry and disappointment, and a small fortune in postage stamps." He had time for only a short explanation of the machine before he was called away, but the book of instructions was clear and concise. She studied the illustrations and diagrams for awhile with her whole attention concentrated on them. Accustomed to picking up new crochet stitches and following intricate patterns from printed directions, it was an easy matter for her to master the intricacies of the new machine. Several times she stopped Jack in passing to ask him a question about some movement or adjustment, but in the main she experimented until she could answer her own questions. In a little while she could shift the ribbon or flip a sheet of paper in and out with the ease of an expert. Then she began studying the keyboard, to learn the position of the letters, and after that it was only a question of practice to gain speed. Fingers that had learned nimbleness and accuracy of touch in other fields, did not lag long here. Hour after hour she sat at the machine, practising finger exercises as patiently as if the keys were the ivories of a grand piano.
