Contains fragments of charcoal, and 
occurs overlying the ordinary quartz 
pebble cement, and underlying thenewer

it, from which a good spring of mineral 
water issues. No gold was obtained.

and 24 N.E. 
Fresh-water limestone, It yields a 
good building lime, and may be made 
into cement, when mixed with a proper 
proportion of clayey matter; the best 
adapted for this purpose is a decom- 
posed basalt, from the Older Volcanic 
rocks. Higher up the Duck Ponds 
Creek, wells haye been sunk, showing
