four inches, as found in wells in Onaga, to ten or more inches on 

 French and Mound creeks, in this township, and on Coal creek, in 

 Grant township, to the east. In places the coal is overlain with a 

 dark, tough stone about six or seven inches thick. 



The different limestone strata contain fossils in varying abundance. 

 The Neva limestone usually has its surface covered with numerous 

 Fusuliiia cyllndrica, half an inch to a quarter of an inch long. Lime- 

 stones Nos. eS, 5 and 9 do not as a rule contain many fossils, but No. 7, 

 the Onaga limestone, has many fossils, consisting of species of Lo- 

 phophyllum, Productus, Enteletes. Pinna, Beticularia, Allorisma, 

 Spirifer, and many crinoid stems. Fossils, with one exception, have 

 not been found in any of the shales. In a well dug a mile south of 

 where our section was measured, in shale-bed No. 10, and what we 

 should judge to be near the base of the shales, there were found many 

 specimens of a species of a Productus. It is in this bed of shales, as 

 has already been mentioned, that our fossil plants occur. In several 

 wells sunk about a dozen rods west of the quarter stone on the south 

 side of section 2, township 6, and range 11, numerous plant remains 

 have been unearthed at a depth of from seven to eighteen feet. A 

 quarter of a mile north of the above-mentioned corner-stone, while 

 digging a pond, quite a number of species were also collected, but in 

 less numbers than at the first-named locality. The species collected 

 at the wells consist of the following : 



1. 3Iariopteris; probably 31. cordato-ovata Weiss, var. obtusa. 



2. Odontopteris ; probably O. {Lescurfypteris) moori (Lx.) Dw. 



3. Daubreea ; perhaps two species. 



4. Neuropterls scheuchzeri Hoffm,; a variety not yet described. 



Besides these there are a number of others not yet identified. At 

 the pond were collected the following species : 



5. Annidaria stellata {S(ih.\ot][i.)Woodi; narrow form. 



6. Asterophyllites equisetifortnis (Schloth.) Brongnard. 



7. Neuropteris odonfoj^teroides F. & W.? 



8. Neuro2}teris 2il'icata Sternberg; as applied by Lesquereux, 



9. Neuropteris scheuchzeri Hoffm.; same as No. 4. 



10. Neuropteris s^^.; apparently a new form, 



11. Odontopteris brardli Brongn, 



12. Pecopteris hemiteloides Brongn, 



13. Pecop)teris newberriana F. & W, 



14. Pecopteris oreopteridia? (Schloth.) Brongn. 



15. Radicites eapillarens (L. & H.) Pat. 



Of the species collected at the pond, Nos. 5, 6, 11 and 15 were not 

 recognized at the wells, though species, which may be forms of Nos, 5 

 and 8, were also found at the last localities. Also, the species of 

 Dauhreeas which occur at the wells were not seen at the pond. 



It was ascertained that the outcrops of the different strata on the
