 (?) Goodnight (Paloduro) Beds. 



In 1893 Cummins proposed a new horizon, the Goodnight 

 beds, placing it, in time, between the Loup Fork and Blanco 

 divisions. In thus placing these beds he says: "I do this on 

 both stratigraphic and palaeontologic grounds. In making a 

 stratigraphic section of the country, I found that the Good- 

 night fossil beds were above the conglomerate bed of the Loup 

 Fork section made at Clarendon, the Clarendon beds being 

 near the base of the Tertiary and below the conglomerate, 

 while the beds at Goodnight were nearly at the top of the 

 plains." 



Following are Cummins's sections taken at the typical lo- 

 cality on opposite sides of Mulberry Canon near its mouth: 



North Side. 



1. White sandy clay, concretionary 60 feet 



2. Sandy clay 40 " 



3. Reddish sandy clay 25 " 



4. Conglomerate, cross-bedded 20 " 



5. Red clay, to the base 80 " 



225 feet 

 South Side, abovit one mile from the preceding section. 



1. Concretionary yellow limestone 4 feet 



2. Yellowish clay, with small concretions 12 " 



3. Concretionary limestone 3 " 



4. Yellowish sandy clay 40 " 



5. Hard stalactite limestone, breaking into conchoi- 



dal fracture 3 " 



6. Yellowish sandy clay, with small concretions, less 



concretionary at base 80 " 



7. Bright red clay 40 " 



8. Soft dark red sandstone 20 " 



9. Soft limestone 4 " 



10. Red clay, with white spots 20 " 



226 feet 



A careful study of this region has compelled the writer to 

 disagree with Mr. Cummins both as to the correctness of his
