3 inches thick and then other salt beds, alternating with sim- 
ilar shales. One bed of lift, has been reached and the end is 
not yet. 
The section of the shaft is of course of more value than the 
drill record, and we give it here as far as it has progressed : 
SECTION OF KINGMAN SALT SHAFT TO THE DEPTH OP 820 FEET. 
"Red-beds" — Red arenaceons, limestones, ferruginous clays, ^ 
and clay shales with thin streaks of gray shales and bands \ 450 ft.

Gray or bluish "slate," with 2 ft. of limestone at 500 ft. 
Red clay shale 
Gray "slate,'' with occasional streaks of limestone, 2 to 8 in. 
thick, and some salt partings and satin spar with ferru- 
ginous stain.

The shaft makes clear a division that the borings with a 
churn drill, left in doubt, viz : That there are gray beds below 
the red beds. The salt is at the bottom of the gray beds. 
The Quaternary and some Tertiary deposits hide the outcrop 
of the red beds to the east to a great extent, but in several 
places in Sumner county ,the lowest of the red beds are seen rest- 
ing on gray beds, which at one time the writer took to be Per- 
mo-Carboniferous. At Wellington, however, near the east mar- 
gin of these gray beds, the salt is found in thinner veins near 
the bottom and this with the total absence of fossils, leads 
me to call the gray beds, at least temporarily the Saliferous 
horizon^ and class them with the red-beds as Triassic. I have pre- 
viously stated my opinion that the Saliferous horizon is contin- 
uous without break, upward from the Permo-Carboniferous 
strata, which are well developed further east. The evidence of
