2. The education of the worker. Quite aside from the fact that the reading matter interests, amuses, or rests him, the worker is educated by his reading. It is this side of the movement that has most interested sociologists and educators. The chief trouble with the worker to-day is that he needs more and more education. The average worker has two obstacles. In the first place, he has a limited vocabulary that retards his speed in reading. In the second place, he cannot read educational matter fast enough to hold his attention. Through the reading matter put at his disposal, he does learn more words,--both how to recognize them and how to use them. He thus becomes better able to express himself, as well as a more rapid reader. Of course this implies mental development. The worker who is better educated to start with also acquires more vocabulary and more speed. It may be a technical instead of a general vocabulary, but the development is the same. 3. The stimulation of invention. This takes place through the ideas obtained from the technical magazines and trade catalogs. We have noted time and again men who have said, in effect,--“You know I got this idea from an article I read from the box;” or, “You know I have had this idea for a long time, but I could not see exactly how to work it until I saw a picture in a magazine I got out of the Home Reading Box;” or, again, “I saw a picture the other day that suggested something that we could use on my machine. I am going to turn in the suggestion to the Suggestion Box.” The suggestion box and its use are to be described at length later. 4. The stimulus towards making suggestions for prizes. It is noted here that the reading not only stimulates the worker making suggestions, but gives him a chance to put his ideas into more practical and working shape. Where the Suggestion Box has been running some time before the Home Reading Box has been put in, we note the sudden rise in the number of suggestions offered after the installation of the Home Reading Box.
