8. Thin bedded, pure limestone, with earthy partings. Much 

 broken up by weathering. Top of small quarry. 2 ft. = 15 ft. 

 2 in. 



Dalmanites callicephalus, c, Asaphus platycephalus, c. 



9. Covered to floor of main quarry. About two feet. 17 ft. 

 2 in. 



10. Heavy bedded, characteristic Birdseye limestone, carrying 

 no fossils. It splits readily into very regular blocks and is much 

 quarried. 3 ft. = 20 ft. 2 in. 



11. Impure, thin, shaly limestone, with neither fossils nor 

 calcite-filled tubes. 6 in. = 20 ft. 8 in. 



12. Pure, thin bedded (about four to six inch beds), light buff 

 limestone, filled with Phytopsis tubulosns. This is the top of the 

 Birdseye, but there is no bedding plane between it and No. 13. 

 The dividing line is marked by a very abrupt change from light 

 to dark color and is very noticeable in the walls all around the 

 quarry. The Phytopsis tubes stop exactly at the top of the light 

 colored rock. 2 ft. 8 in. = 23 ft. 4 in. 



13. Dark gray, lumpy, fairly pure limestone, with numerous 

 fossils. Black River. 5 ft. 6 in. = 28 ft. 10 in.
