Among the subjects continually described in newspapers and magazines, and even on billboards and in street-car advertising, is the subject of hygiene. No greater service can be rendered the community than for those who are conducting discussions of health to teach people how to read correctly this mass of information regarding health, to separate misinformation from information, and to apply the lessons learned to personal and public hygiene. There is no better way of doing this than to teach a class or a child to clip out of magazines and newspapers all important references to health, and then to classify these under the subject-matter treated. A teacher, parent, or club leader might practice by using the classification of subjects outlined in the Contents of this book. It is surprising how rapidly one builds up a valuable collection serviceable for talks or papers, but more particularly for giving one a vital and intelligent interest in practical health topics. Interested in comparing the emphasis placed on health topics in a three-cent paper having a small circulation with a penny paper having twenty times the circulation, I made during one week thirty-eight clippings from the three-cent paper and ninety-five from the penny paper. The high-priced paper had no editorial comment within the field of health, whereas the penny paper had three columns, in which were discussed among other things: _The Economics of Bad Teeth_; _Need for Individual Efficiency_; _"Good Fellows" Lower Standard of Living by Neglecting their Families_. The penny paper advertised fifty-two foods, garments, whiskies, patent medicines, or beautifiers urged upon health grounds. In the three-cent paper twenty-six out of thirty-eight items advertised food, clothing, patent medicine, or whisky. One issue of a monthly magazine devoted to woman's interests contained twenty-eight articles and editorials and fifty-five advertisements that concern health,--thirty-seven per cent of total reading matter and thirty-seven per cent of total advertisement. Excellent discipline is afforded by this clipping work. It is astonishing how few men and women, even from our better colleges, know how to organize notes, clippings, or other data, so that they can be used a few weeks later. There is a satisfaction in seeing one's material grow, as is remembered by all of us, in making picture scrapbooks or collections of picture postal cards and stamps. "Collections" have generally failed for want of classification,--putting things of a kind together. Chronological arrangement is uninteresting because unprofitable. One never knows where to find a picture, or a stamp, or a health clipping. Clippings, like libraries, will be little used if not properly catalogued so that use is easy. If a health-clipping collection is attempted, there are four essentials: (1) arrangement by topic; (2) inclusion of advertisements; (3) inclusion of items from magazines; (4) cross references.
