The paper presents evidence that the coal-bearing rocks of the 

 Raton field are divisible into two formations, the lower one 

 possibly older than Laramie and the upper one of post-Laramie 

 age.

The paper includes geologic sections of the older rocks up to 

 and including the Dakota sandstone in the Cerrillos and Hagan 

 fields.

The geology along the Santa Fe Railway from Albuqueniue 

 westward is described. The Cretaceous consists of the following 

 formations, given in descending order: Laramie, coal-bearing; 

 Lewis shale; Mesaverde, coal-bearing; Mancos shale, locally coal- 

 bearing ; Dakota sandstone. 



(P. 58) Gardner's results are accepted for the Xacimiento 

 region and Herrick and .Johnson's for the Rio I'uerco region. 

 Herrick's section in the Rio Puerco Valley (78, p. 338) is quoted 

 with several changes, and the reference of the coal-bearing rocks 

 including the "Punta de la Mesa sandstone" to the Fox Hills is 

 accepted. 



A section of rocks exposed at Laguna, west of the Rio Puerco 

 coal field, was measured. The following fossils occur about 550 

 feet above the base of this section: Exogyra columheUa Meek; 

 Gi-yphwa sp., probably a variety of Gryphoea neicherryi : Avicuhi 

 (jastrodes Meek?; Cardiion, Panopea. Turritella, RosteUites, and 

 Fits us sp. 



About 100 feet lower in the section the following species were 

 collected: Exogyra eoJumhelJa Meek; Peeten sp. ; Pinna pefrina 

 White: I)iocerann(s ?, Leda, Cardium, and Lucina ? sp. : Isoeardia 

 n. sp. ; Cyprimeria 1 sp., Corbula sp. ; Liopistha (Psilomya) 

 concentrica Stanton: Turritella icJiitei Stanton; Tritonium lano- 

 T>ense Stanton; Actceon, Cinulia. TiirriUtes 1, or Hetcroceras sp. 

 Doctor Stanton is quoted as reporting that these fossils indicate 

 a horizon in the Benton formation.
