merous small streams and ravines, creating in most places a well- 

 defined escarpment for a distance of about nine miles. In several 

 places it extends south in the high ridges into Greenwood county. 



In sections 25 and 26, in township 21, range 12, near the head 

 waters of Smith and Four Mile creeks, is an outlier a mile or more in 

 length by one-half mile in width. 



There is a quarry located near the center of section 33, township 

 21, range 12, and another in the southeast quarter of section 22, same 

 township and range. 



From the last-mentioned quarry the outcrop extends nearly north 

 along the west side of Hoosier creek three miles. It then angles to 

 the northwest, skirting the south branches of Eagle creek, to section 

 31, township 20, range 12. A good quarry is located near the north- 

 east corner of the southeast quarter of said section, in a bluff about 

 fifty feet above the creek. 



The stratum passes under the creek one mile farther up. Thence 

 it trends northeasterly five miles, where it crosses the divide between 

 Eagle creek and the Neosho river, in section 16, township 20, range 

 12. A good quarry is situated on an outlier, near the southeast cor- 

 ner of section 14, from which stone has been taken for a number of 

 bridge abutments. 



Another outlier, one-half mile or more in length, is found in sec- 

 tions 8 and 4, and another smaller one at the summit of Chicago 

 mound, in section 34, township 19, range 12, where a quarry has been 

 extensively worked. This is the exposure that Kirk erroneously 

 called the Emporia limestone.^ 



The stratum referred to on the same page as the Wyckoff limestone 

 is equivalent to the one termed "Burlingame" by Haworth and 

 "Barkley" by Adams.^ 



From the south side of section 10, township 20, range 12, the gen- 

 eral trend of the outcrop is west, flanking the ravines that flow into 

 Coal creek from the south six miles to a point four miles north of 

 Olpe, where it passes under the creek. Thence it extends northeast 

 five miles to a bluff on the south bank of the Cottonwood river. 

 Thence west, passing through sections 31, township 19, range 12, and 

 section 36, township 19, range 11, where the most extensive quarries 

 on the outcrop are located. Many thousand cords of dimension 

 stone have been taken from these quarries for use in Emporia and 

 vicinity. The ledge passes under the flood-plain of Coal creek three 

 miles south and one-half mile west of Emporia. The footing of the 

 dam at Soden's mill, on the Cottonwood river, rests on this stone. It 

 is also found in wells at Emporia from twenty to forty feet deep, but
