Fossil leaves collected from the coal measures near Cerrillos 



are incliuled anioiig the "Tertiary plants:" Popiilus halsomoides 

 Gopp. ; Quercus platanca (?) Ileer ; Ficus tlliocfoUa Heer ; Pla- 

 tanus guillclmw Heer ; Cinnamomum misslssippiense Lesq. ; Mag- 

 nolia; GarpolUhcs spirales Lesq. ; CarpoUthes compositus Lesq. ; 

 CarpolUhcs mexicanus Lesq. [Inasmuch as the coal-bearing 

 rocks now known to l>e Mesaverde were not distinguished by 

 Lesquerenx from the younger rocks of probable Tertiary ago, and 

 inasmuch as both formations are plant-bearing, it is possible 

 that these fossils may have come from the Tertiaiy as their 

 names suggest, rather than from the coal-measures, as he sup- 

 posed.]

 report in 1869.) 



The coal beds near Cerrillos are described (p. 167). The 

 coal-bearing rocks containing "abundant impressions of decidu- 

 ous leaves" are referred to the Tertiary, and the Galisteo sand- 

 stone is correlated with the Monument Creek formation of the 

 Denver region. The Galisteo is described as lying conformably 

 on the coal measures. (P. 98) An analysis is given of the 

 "Placer" anthracite.

The occurrence of coal near Cerrillos, New Mexico, is referred 

 to, and E. T. Cox (p. 298) mentions his former visit to the 

 anthracite mine.

(P. 363) The author refers to coal measures in Tijeras Can- 

 yon, and near San Felipe (probably in the Tijeras and Hagan 

 coal fields) ; also at other localities farther west. The Placer 

 Mountain coal beds (Cerrillos field) are correlated with those 

 at Raton, New Mexico, and with those of the Canyon City field 

 in Colorado.
