Relief Models Now Used, ·. Recognition of this shortcoming on the part of the old-fashioned map, hás resulted in the substitution of the relief model-a reproduction of an area in a form true to nature. This is a form of map that may be read by a childi Ita topographic fucts are easily grasped and vividly retained. Hills, valleys, streams and other details stand forth in other. In 'effect the new form of mup. their proper relationship the one to the

He sees things in the form to which his eyes are accustomed.
For certain special military purposes the relief medel possesses advantager over maps of all other forms. Unfor- tunately, however, it is an object of considerable bulk and not easily trans ported, and its reproduction in quan- tity is a slow and laborious process. For these reasons: the use of the model is confined to the headquarters of the higher commands.
Because of the value of the model and the diffulty of supplying an entire army with faithful copies, the
އ
engineers of the United States Army have developed a type of map which seems to meet the requirements. This evolution takes the form of a pictorial relief map which plctores, the territory In a manner approaching that of the model. The approved pictorial relief map has all the accuracy of detail of the old contour type, with the addition of a striking photographic reproduc- tion of the "ay of the land."
The slopes and elevations are printed as "shadow map" over the contour lines," an undertaking achieved by the use of medel. high-light photographs of a relief The photograph covers the same area that is embraced in the
contour map.
By combining the two the army finds it possible to give pro cise engineering data and visual re production of the territory in a single exhibit.
