This limestone (No. 12), probably of Upper Eocene age, is a sample 
of the stone used by the late “ Schnapper Point Cement Company.” The 
percentage of siliceous matter is too low for a good hydraulic lime, Its 
power of hardening under water would be considerably increased by the 
addition of clayey matter in such proportions, as to raise the quantity of 
silica to about 25 per cent. :
