13. Light-gray limestone in 4 layers, with shaly 



partings, varying in thickness from 19 to 21 



inches. Lithologically similar to subjacent 



layers 1 8 =>= S3 o 



12. Light gray, with dark-gray spots and blotches, 



compact limestone, which is harder than lower 



layers and varying in thickness from 125 to 13 



inches 1 £ =t 81 3% 



11. Gray, weathering to a brownish color, gritty 



shale, about 1 inch thick 1 ± So 3 



10. Layer lithologically about the same as the sub- 

 jacent one 5 80 



9. Light to slight ly brownish-gray with dark-gray 



blotches and spots of hard limestone, varying in 



thickness from 14 to 16 inches. Mr. Harry H. 



Brandon of the Jackson Stone Co. stated that 



the Laurel limestone worked in this quarry, 



Nos. 9 to 16, inclusive, with a thickness of 7 



feet 1 inch, is a superior rock for macadamizing 



roads and in respect to its binding quality is 



one of the best in the state 1 3 ± 79 9 



8. Light-gray limestone blotched with dark-gray 



spots and streaks from pyrite. Calcite crystals 



are also present . It is a hard layer which forms 



the present tloor of the quarry (.August, 1914), 



and its upper surface is undulating, forming 



sort of dome-shaped elevations 5 78 6 



7. Gray, gritty shale and perhaps rather calcare- 

 ous 3 =fc 78 1 



6. Light-gray limestone blotched with spots and 



streaks of darker-gray color, which are due to 



pyrite in small grains that has discolored the 



rock, when weathered it changes to a brown 



or rather rusty color. The /one varies in thick- 

 ness from 16 to 17 inches and is the base of the 



Laurel limestone, which in this quarry has 



a thickness of 9 feet 1 inch 1 4'. 77 10 



5. Osgood beds. — Dark-gray shale, very gritty to 



the teeth, which is exposed in upper part of pit 



in floor of quarry. The measurements and
