110 CEMENT MATERIALS AND INDUSTRY. [bull. 5 
At two points, one of them one-fifth of a mile northeast and 1 
other 500 feet east of the Bozeman house, the chalky marls occur higl 
in the formation and are still more sandy than that of No. 4 in the s 
tion given on page 109. , These outcrops are in the heads of narr 
gulches which descend to the Deciper Valley. At the locality 500 f<> 
east of the house the marl is very sandy, partially indurated, and c< 
tains numerous casts of fossils similar to those found near the top 
the formation at Dobyville. The exposures here show about 10 f< 
of marl and are just below the springs which now from the base of 1 
stratified yellow sands and blue clays. 
About 10 feet of interstratified sand and clay is exposed above t\ 
sandy marl, and then follows an overwashed yellow sandy soil to 1 
top of the hill, 40 feet above. 
One-fourth of a mile southeast of Mount Bethel Church, near t 
northeast corner of sec. 33, T. 7 S., R. 20 W., beds similar to the 
east of the Bozeman house are exposed. Here a spring issues fr< 
the contact between the chalk-marl and the overlying sand and bl 
clay. The top of the marl is 70 feet below the crest of the hill. 
The chalky sand of the upper part of the Saratoga formation 
exposed on the Arkadelphia-Okolona road, on the west bank of li 
Deciper Creek, near the middle of sec. 34, T. 7 S., R. 20 W., as w^ 
as in the bluff of the creek near by. The top of the sandy marl, who 
stands here 20 feet above the creek, contains casts of fossils as at t 
Bozeman place, and is overlain also by the same kind of interstratill 
sand and clay. 
Twenty feet of the even-textured lower and more chalky meml 
of the Saratoga chalk-marl is exposed in the road cut on the Arl 
delphia-Okolona road, 100 yards west of Little Deciper Creek. 
Sand and clay conceal the higher beds of the chalk-marl. The G\\ 
phcea vesicularis bed, with underlying blue marl, outcrops a few f< 
above the creek bottom. 
One-half mile above the road, on the Wright place, the lower 30 fc 
of the Saratoga formation is exposed in the gullies at the west side 
the creek bottom. The lower 10 to 15 feet of the marl is identica 
the same as that found at the road and on the Bozeman place west 
Big Deciper Creek, as shown in analysis 26, page 111. The ba 
member of the chalk-marl, containing the same indurated shell bd 
outcrops here at about 10 feet above the creek bottom, and below 
is the blue marl. Yellow sandy clays overlie the chalky marl herej 
in the exposures noted on Big Deciper Creek. 
At the east side of the creek bottom, on the Arkadelphia-Okolc 
road, and northward through the Haskins place, the lower part of t 
chalk-marl is exposed in gullies in an abandoned field.
