While in the field the present writer assumed that the Mesaverde age 

 of the coal measures near Cabezon was established, and bis purpose in 

 visiting this locality was to collect fossils from the Mesaverde for the 

 purpose of correlating with it the coal-bearing rocks which in the fields 

 fartlier east contain similar fossils. A large number of petrified logs and 

 stumps of trees were found in the lower part of the Mesaverde north of 

 Cabezon, and leaf impressions occur in the same beds, but most of these 

 were too poorly preserved for identification. However, beautifully pre- 

 served leaves were found in a thin layer of fine-grained sandstone about 

 400 feet above the lowest bed of coal. The locality is about 5 miles 

 northwest of Cabezon, in a steep bluff half a mile north of a small arti- 

 ficial lake. The species collected are as follows :

Fragments of palm leaves were found 50 to 100 feet above the bed 

 yielding these plants, but no fragment was found with the parts necessary 

 for the identification of species. Still higher in the formation, at the
