with your manuscript should exhibit a high degree of 

 professional skill and an exactness fitting the technical 

 paper. 



You may refer to many manuals for guidelines to good 

 graphic presentation, but we shall include some of the more 

 important fundamentals here. 



When illustrations meet graphic standards, they harmo- 

 nize with each other and with the printed page in size and 

 density of lines and lettering (see fig. 5). Heavy tones in 

 letters and rules are avoided, and the importance of the 

 various parts of the line drawing is shown by the variation 

 in weight and size of letters and thickness of lines. The 

 lettering should not be less than 8 points nor more than 

 12 points after reduction. (A convenient place to find type 

 sizes is in Webster's New International Dictionary or in 

 the New Collegiate Dictionary.) 



Artist's Illustrations 



Artists often can produce a drawing that will be more 

 graphic than a chart or a photograph. In instances when 

 photographs are not available, a good drawing or painting 

 is very useful. 



Such illustrations should be in black and white. Pen and 

 ink, brush and ink, or scratchboard drawings reproduce 

 as linecuts; wash drawings reproduce as halftones. Pencil 

 drawings, oil paintings, and color work do not as a rule 

 reproduce effectively and should not be used. 



Unless you are a competent artist, do not attempt to 

 produce such illustrations, but rather have such work done 

 for you by qualified illustrators. 



Photographs 



Photographic illustrations may be valuable supplementg 

 to the text. They help the reader gain an understanding of 

 the subject more rapidly and more easily. Effective planning 

 requires a number of photographsfrom which to choose your 

 illuBtrations. Submit only good quality photographs that have 

 a close relation to your subject. Occasionally, you may 

 need to use a photograph of lesser quality but of historical 

 value. Study publications of the Service and of outside 

 organizations to see how photography was used to emphasize 

 and clarify the subject. 



Although you are concerned primarily with subject 

 matter when selecting photographs, you must give thought
