Geological Survey, consisting of red and black triangles upon a white background. 

 Sheets will be printed and will be issued by the property clerk, as expendable prop- 

 erty, containing the strips required for a rod 12 feet long, and with an additional 3 

 feet, which may be used either to make a longer rod or to repair any portion of the 

 pattern which has become injured. Each sheet will contain printed directions for 

 making the rod, briefly as follows: 



A strip of light wood 12 feet long, 3i inches wide, three-fourths of an inch thick, is 

 given a coat of shellac or varnish on its face and the strips of pattern are cut out and 

 laid upon it dry. This is to avoid any change of scale in the paper, due to moisten- 

 ing. The dry paper should be quickly pressed flat upon the moist surface, matched 

 end to end, and when dry its upper surface may be given a coat of shellac or varnish 

 to protect it from the weather. 



This will avoid the shipments of expensive and nonexpendable stadia rods and the 

 accountability for them at the close of a survey. They can be made as often as 

 required and may be thrown away when no longer needed. 



It is believed that these two rods will meet all of the demands in the Forest Service 

 for level and stadia work. In an emergency either rod can be used for either purpose, 

 the level rod being best adapted for precise work or short sights and the stadia for 

 rough and quick work. The question of dividing the stadia rod into two or more 

 pieces and the method of joining them may be left to the fancy or ingenuity of the 

 surveyor. A strap hinge for folding the rod can be purchased at any hardware store, 

 as can also the bolts or hasps, which others might prefer for a lap joint. A cleat about 

 2 feet long and the same size as the rod will usually be found necessary to make the 

 joint rigid. 

 Loose Leaf Covers 



The property clerk will issue to supervisors, on requisition, loose covers 21 by 18 

 inches, binding on the 18-inch side, for holding township plats. Also loose leaf covers 

 18 by 21 inches, binding on the 21-inch side, for standard atlas sheets. It will be nec- 

 essary to preserve township plats with the greatest care, as it will not be possible in 

 the majority of cases to obtain duplicates. 

 Forest Atlas Legend Crayons 



The property clerk has installed a machine for printing the Forest Atlas legend ' 

 upon each colored crayon, and it is expected that this improved method of marking 

 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 pos- 

 sible for the property clerk to obtain hi each case the best grade of a standard color, 

 and, disregarding the manufacturer's number, print the atlas legend upon the pencil. 

 Thus, the bright yellow crayon will be marked " Grassland, barren, etc., " and " Open 

 for sheep and goats only." 

 Standard Scale Diagrams and Maps 



The proclamation diagrams were originally intended to be only a graphic repre- 

 sentation of the land, by townships and subdivisions, to be included within the 

 boundaries of a National Forest. It was found, however, that they serve, though
