The property clerk has installed a machine for print- 

 ing the Forest Atlas legend upon each colored crayon, 

 and it is expected that this improved method of mark- 

 ing will lead to greater accuracy in the use of colors on 

 maps. There have always been some uncertainties, 

 due to the fact that many men are not good judges of 

 color, and also because the makers of colored crayons 

 change the formulae for mixing colors or use different 

 grades of pigment. It has also been found in the case 

 of some colors that they change materially with age. 

 Under this new method of marking it will be possible 

 for the property clerk to obtain in each case the best 

 grade of a standard color, and, disregarding the manu- 

 facturer's number, print the atlas legend upon the 

 pencil. Thus, the bright yellow crayon will be marked 

 "Grassland, parks, etc.," and "Open for sheep and 

 goats only." 



On important work a legend showing the colors and 

 symbols used and their significance should accompany 

 each map or folio.
