 the subject could correctly apply them, and they should be so definite 

 as to admit of little or no disagreement in interpretation. Neither 

 of these ideal requirements can be realized. 



The workability of coal at a given point to-day depends on factors 

 of two types. Those of the first type— such as quality, thiclmess, 

 and depth— are intrinsic; those of the second type— such as rail- 

 road transportation and markets— are extrinsic. To-day the extrin- 

 sic factors may determine absolutely the commercial workability of 

 a bed of coal at any locality. A coal bed 75 miles from a railroad 

 and 50 miles from the nearest town, no matter how valuable it may 

 be some day, has to-day a value that is purely prospective, depend- 

 ing on an unknown factor— the time when trajisportation shall
