price we pay is utter confusion in our source impres- 

 sion of size. 



Scales should be standardized into one uniform set of 

 scales, easily transferable from one into another; e.g. 100 

 miles to an inch, 50 miles to an inch, 20 miles to an inch, 

 10 miles to an inch, and 1 mile to an inch. It should be 

 possible to get a map of any country in any of the stand- 

 ard scales. This "would make possible direct comparison 

 of size by superposition of the maps. Such scales as 

 6V2 miles to an inch and 22% miles to an inch, simply 

 should not be used, because the distances on such a map 

 will not be translated into miles. Recent publications 

 are moving in this direction, but confusing scales are 

 still very abundant.
