A geologic sketch map, showing the distribution of the forma- 

 tions from Cabezon eastward to Hagan. is given. 



(P. 79) The author's Fox Hills includes the sandy rocks below 

 the coal ; and the coal-bearing rocks, 500 feet thick, are de- 

 scribed as "Fort Union'' or "Laramie.'' His "Fox Hills" and 

 "Fort Union" constitute the "Fox Hills" of Herrick and John- 

 son and the Mesaverde of later writers.
