A section from Medicine Lodge to the top of the Gypsum Hills, 
six miles southwest. was measured by the barometer. It is thought, 
however, that the thickness of the different divisions is quite accu- 
rately given since the total thickness of the beds agrees very closely 
with the altitude of the hills above the level of the Medicine Lodge 
river, which is 350 feet according to the Medicine Lodge sheet of the 
U.S. Topographic map.

4. Massive gypsum on top of the Gypsum Hills, 6 29—349 
miles southwest of Medicine Lodge. The JAledicine 
Lodge gypsum of Cragin. 
3. “Tron rock” of the quarrymen, at the base of the 90—320 
massive gypsum. Then, mainly red_ shales, 
though other colors occur with thin layers of 
gypsum and selenite. 
2. Greenish-gray sandstone, containing nodules of S80—230 
gypsum, forming a conspicuous stratum near the 
base of the steepest part of the hills. Below, 
mainly red shales with some thin layers of 
gypsum. 
1. Mainly soft red sandstones with some shales, con- 150—150 
taining gray to greenish-gray layers and spots.

Nos. 2 and 3 of the above section belong in the division which 
Professor Cragin has named the Flower-pot shales. The soft red 
sandstones below these shales, forming the upper part of No. 4, 
belong in the Cedar Hills sandstone of Cragin, while the base of the 
bluffs near the river is probably in the division that he terms the 
Salt Plain Measures, though there is hardly any line of separation 
between the two divisions. 
On top of the Gypsum Hills, eight miles by the road, southwest 
of Medicine Lodge, is Best Brothers’ quarry in the massive ledge of
