"No, of course not. If they did, they would do little else," smiled his father. "Nevertheless, they glance at it and now and then, as their eye travels over it, an item on the page catches their fancy. Any artistic advertisement will usually command attention; so will the receipt of some trifling article that is pretty or novel. Besides, it is chiefly the rushed city person who tosses the advertisement away unread. Those with more leisure, country people, perhaps, who receive little mail, usually read every word of the printed matter that reaches them. They do not have so many diversions as we do, and this printed stuff entertains them and keeps them in touch with the cities. Therefore they generally go over what is sent them quite carefully. Frequently they are miles from large shops and are forced to do much of their purchasing by mail, so such catalogues are a great convenience to them." "I can see that," Paul admitted. "Yes, indeed. Catalogues to those living in sparsely settled districts are a profound blessing. I should not be surprised to see the paper, ink, and printing business one of our largest industries. We cannot do without any of these commodities. Have you thought, for example, of the amount of material and labor that goes into producing the millions of thick telephone directories annually circulated among the subscribers? All these have to be printed somewhere." "It must be an awful piece of work to get them out, Dad." "It is. They must be printed absolutely correctly too, for an error will cause both the exchange and the subscriber no end of trouble. So it is with residence directories and many similar lists. If you consider, you can readily see that as a nation we consume an unbelievable amount of paper and ink in a year. That is why the shortage of these materials during the war caused such universal inconvenience. And not only do we demand a great deal of paper, and ink, and printer's skill in every department of our business, but being a country alert for education, we annually use a tremendous number of schoolbooks. Hundreds, thousands, millions of schoolbooks are printed each year for the purpose of educating and democratizing our growing citizens." Paul stirred in his chair uneasily. The talk had drifted back into the familiar channels of the present. Again the school, Mr. Carter, the fifty-dollar bill, and the thoughts that for the instant had taken flight now returned to his mind, bringing a cloud to his face. His father, noticing the shadow, looked kindly into the boy's eyes. "You are tired to-night, son," he said. "A little." "Not working too hard?" "No, sir. I don't think so." "Everything going all right at school?" "Yes." "Paper still booming?" "Yes, Dad. Going finely." "I am glad to hear that."
