 is 117 feet. 



3. Green and purplish sandstone shales, very much metamorphosed, 60 



feet. 



4. Volcanic, (trachyte ?) 4 feet. 



5. Purple metamorphosed slates, 5 feet. 



6. Volcanic, (trachyte ?) 4 feet. 



7. Coarse brown sandstone, very much metamorphosed, bat rather 



uniform in structure, 100 feet. 



8. Volcanic, (trachyte ?) about 20 feet. 



9. Very hard, dark sandstone, in layers, 6 or 8 inches, 50 feet. 



10. Light-brownish sandstone with streaks of dark-brown, 30 feet. 



11. Volca,nic, (trachyte ?) 20 feet. 



12. Dark- gray sandstone, 70 feet.

with debris. Thickness, about 80 feet.

pebbles : above, it has a pinkish tinge ; 10 feet. 



23. Hard-red sandstone in laminse of 2 to 3 inches, 5 feet. 



24. Compact sandstone, with general color gray, but becoming pinkisji as 



we go down, 30 feet. 



25. Eed shales, 4 feet. 



26. Compact sandstone, pinkish and calcareous above, gray below, 5 feet. 



27. Dark-blue limestone, containing veins of calcite, and without fossils, 



2 feet.
