"I'm rather glad of that," he remarked, "for it is much more interesting to explain a process to a person to whom it is entirely new. Formerly the method of setting type for the press was a tedious undertaking and one very hard on the eyes; but now this work is all done, or is largely done, by linotype machines that place in correct order the desired letters, grouping them into words and carefully spacing and punctuating them. The linotype operator has before him a keyboard and as he presses the keys in succession, the letter or character necessary drops into its proper place in the line that is being made up. These letters are then cast as they stand in a solid, one-line piece. With the lines thus made up, the compositors are relieved of a great proportion of their labor. Later I will show you how this is done. "In the composing room there is also the monotype, another ingenious invention, which produces single letters and prepares them for casting. With two such machines you might suppose that the compositor would have little to do. Nevertheless, in spite of each of these labor-saving devices, there are always odd jobs to be done that cannot be performed by either of these agencies; there are short articles, the making up and designing of pages, advertisements, and a score of things outside the scope of either linotype or monotype." Paul listened attentively. "After the words have been formed and the lines cast by the linotype, the separate lines are arranged by the compositors inside a frame the exact size of the page of the paper to be printed. This frame or form as we call it, is divided into columns and after all the lines of type, the cuts, and advertisements to be used are arranged inside it, so that there is no waste space, a cast is made of the entire form and its contents. This cast is then fitted upon the rollers of the press, inked, and successive impressions made from it. This, in simple language, is what we are going to see and constitutes the printing of a paper." Paul nodded. "Of course," continued Mr. Hawley, "we shall see much more than that. We shall, for example, see how cuts and advertisements are made; photographs copied and the plates prepared for transfer to the paper; color sheets in process of making; in fact, all the varied departments of staff work. But what I have told you are the underlying principles of the project. I want you to understand them at the outset so that you will not become confused." "I think I have it pretty straight," smiled Paul. "Very well, then; we'll get to work." "Not that I thoroughly understand how all this is done," added the boy quickly. "But I have the main idea and when I see the thing in operation I shall comprehend it more clearly, I am sure. You see, I don't really know much of anything about printing a paper. All I am actually sure of is that often the making up of a page is a big puzzle. I've had enough experience to find that out."
