ortions of Chase, Marion, and Butler counties, lying within the Cotnwood quadrangle. The mapping by Prosser and Beede1 brings at the fact that in this district the general westward-dipping monoine of Permian limestone and shales bears two notable domes. One these centering 2 or 3 miles southeast of Elmdale lifts the strata out 200 feet in an area 9 miles wide from east to west and 12 miles ng from north to south. In places the dips are as much as 3° or 4°. the southeast corner of Marion County is the Burns dome, which about 200 feet high and affects a smaller area than the Elmdale ome. The Elmdale dome yields considerable gas, mostly from holes pout 200 to 600 feet deep, and the product has been piped to porons of the surrounding country. Deep holes have been sunk at many places in central Kansas for ater, salt, and oil, but oil has been found in promising amount only 1 the vicinity of Eldorado, Augusta, Dexter, and Eureka, and gas aly about Elmdale, Arkansas City, and Winfield. Large amounts f oil and gas are obtained farther east in Kansas. A list of the eeper holes is given in the following table, but it does not include l holes bored during the last few years. Deep borings in Kansas, longitude 96°-100°, mostly prior to 1902. 1 Prosser, C. S., and Beede, J. W., U. S. Geol. Survey Geol.
