THE BELTS OF VEGETATION 

 The bands of color indicate the various kinds . 

 vegetation. The word "montane" indicates an area in 

 which uplands interrupt a belt of vegetation. This 

 map is based on a Lambert azimuthal equal area pro- 

 jection whereby large areas of the earth's surface can 

 be displayed as if seen from space — in this case, as if 

 from over the state of Nebraska. Actual distances can be 

 measured on it on the scale of miles shown below map.
