of frequent occurrence in the southwest part of the county. The outcrop enters 
the county near the southwest corner and is found along the bluffs on the south 
side of the Verdigris river, elevation, 1225 feet above sea-level; trending up the 
river into Chase county, it crosses, and reappears in Lyon county, in the hills im- 
mediately north of the river. Thence it follows generally a northeasterly direc- 
tion, for eight miles, to a point in section 1, township 21, range 10, where it attains 
an altitude of 1325 feet. Thence it trends northward to the hills one mile south 
of Phenismound. Thence northwesterly, skirting the hills along the head waters 
of Phenis and Jacobs creeks, it leaves the county, passing under the Cotton- 
wood river one mile southwest of Saffordville, in Chase county; elevation, 1110 
feet. Thence it reenters the county in section 6, and extends ina sinuous line 
to the corner common to sections 23, 24, 25, and 26, township 18, range 10, where 
it is extensively quarried on the old Ruggles farm, at an altitude of 1222 feet. 
For the next eight miles the general trend of the outcrop is northwest; returning 
to within one and a half miles of the west county line, it passes under the 
Neosho rivér; altitude, 1130 feet; thence its course is nearly east six miles. 
Thence it bears east of north in a zigzag line, passing between Allen and Ad- 
mire, at an elevation of 1300 feet, where it is quarried for shipment on the Mis- 
souri Pacific road. It leaves the county near the center of the north line. 
The dip of the stone throughout the county is about twenty-five feet to the 
mile, fifteen degrees north of east. 
Quarries and typical exposures are indicated on the map.
