3. Sandstone and sandy shale, Weston 10 



4. Limestone, hard, yellow, with fresh water fossils, 



Redstone 4 



5. Shale 



A sample of this limestone was collected, the analysis 

 of which is reported by Krak as follows : 



Per cent. 



Silica (SiO 2 ) 9.77 



Ferric Iron (Fe 2 O 3 ) 1.59 



Alumina (A1 2 O 3 ) 3.20 



Calcium Carbonate (CaCO 3 ) 78.47 



Magnesium Carbonate (MgCO 3 ) 6.30 



Phosphoric Acid (P 2 O 5 ) .24 



Total 99 . 57 



The analysis shows that this limestone would readily burn 

 into agricultural lime, and its physical character is such that 

 it would make excellent road material.
