bed^ and bed/ commingled with bed a. Following the left fork 

 of the road for a few yards a spring is seen issuing from 

 beneath bed f. After a considerable amount of digging, Mr. 

 Hubbard succeeded in finding traces of Cretaceous fossils in the 

 underlying clay bed. The specimens collected from the limestone 

 include Venericardia planicosta, typical and varietal, Turritella 

 ■mortoni, Cucullcza saffordi, Meretrix ripleyana, Yoldia eborea, 

 Calyptrophorus velatus, et al. 



Bed/" is well exposed in the streets along the eastern border of 

 the village a few hundred yards east of the Court House. 



Bed e is well exposed in the northern outskirts of the town, and 

 our best collection of fossils was made in a pasture about ^ mile 

 out and to the north. The collection includes Levifusiis hubbardi, 

 Volutilithes rugatus var. saffordi, Turritella morto7ii, Cyprcea, 

 Tornatellcea bella, Scaphella, Calyptrophorus velatus, Fusus q7ier- 

 collis, Fusus hubbardanus , Yoldia eborea, Vener^icardia var. smithii, 

 Ciicullcza saffordi and macrodonta? . 



Bed d is well exposed along the Memphis road from % to i}^ 

 miles from Ripley. It contains a few fossils with shells in the 

 condition of white powder but no large well preserved recogniz- 

 able ones were noted. 



On top of a high hill i ^ miles northwest of Ripley, bed a is 

 well exhibited and on either slope a short distance from the 

 summit there are traces of Venericardice — bed c. 



At the roadside i mile east of Ripley Mr. Hubbard collected 

 Fusus tortilisf and Venericardia alticostata Con. var., while i mile 

 still farther east from a splendid exposure of bed g he obtained 

 vast numbers of casts of Turritella mortoni along with Calyptro- 

 phorus velattis var. Cucullcsa saffoi^di, Venericardia planicosta, 

 Mei^etrix ripleyana, Ostrea pulaskensisf and many other less recog- 

 nizable forms. 



Blue Mountain, i. e. the Brougher place of Hilgard's report, is 

 six or seven miles to the southwest of Ripley and furnishes a good 

 Eocene section. The various beds exposed with rough estimates 

 of thicknesses are as follows: 



a. Top of hill. Ferruginous, large concretions in red sand. 



b. 100 feet more or less of reddish sand. 



c. Clay bed, perhaps 20 feet thick; being impervious to the 



waters percolating through b it gives rise to many noble 

 springs, the best of which come forth just above the 

 laundry of the flourishing Blue Mountain college. 



d. Beneath c and around the steeper banks below the spring 



the first fossiliferous bed is found. It is the typical 

 Crainesville gray calcareous clay with green grains and 

 bearing Venericardia var. smithii, Cucullcza saffordi, Tur-
