236 GEOLOGICAL RECONNOISSANCE 



averaging about three inches by two. This siliceous vein traverses the 

 disturbed shales, in a north-east and south-west course, for several miles. 

 Where these quartz veins pass through the property of Dr. David Lewis, 

 in section 24, township 6 north, range 11 west, several shallow pits have 

 been sunk to investigate their character. All that were discovered, proved 

 to be talcose slates and fine transparent crystals of quartz, three or four 

 of which had enclosed a drop of water. These pits I consider too shallow 

 to prove the metalliferous character of the veins. The apparent con- 

 nection of these veins witli those in Pulaski county, which contain 

 argentiferous galena, leads me to suspect that similar ore might be found 

 at a greater depth; especially, as the Bull mountain veins reach the 

 surface through a hard, siliceous slate, which overlies the metalliferous 

 shales in Pulaski. The following is a section of the rocks at the Bull 

 mountain, near Dr. Lewis' house: 



Conglomerate, thin-bedded and shaly sandstones, in all 310 feet. 



Dark, siliceous shales, with bands of prismatic shale, much dis- 

 turbed, and traversed by veins of quartz, in all 75 " 



385 " 

 Near the mouth of the Cadron, veins of milky quartz are found, tra- 

 versing the millstone grit; this appears to be the western limit, on the 

 north side of the Arkansas river, of that subterranean action which has 

 filled or injected the slates, south of the Cadron, in Pulaski county. 



At Springfield, the county seat of Conway county, a qualitative chemical 

 examination was made of the town spring, which issues, in a bold clear 

 stream, from the reddish and dark-colored shales under the millstone grit. 

 It proved to be a good chalybeate water, possessing decided tonic proper- 

 ties. The principal ingredients are: 

 Carbonic acid; 

 Bi-carbonate of lime; 

 Bi-carbonate of magnesia; 



Bi-carbonate of the protoxide of iron (strong). 

 Another chalybeate spring, of the same character, occurs at the Peach- 

 orchard-gap, in section 20, town? hip 6 north, range 10 west, in the edge 

 of White county, and belongs to Mr. Elliott. 



Agriculture. 



The most important tracts of arable land, occupy she southern part of 

 the county, in town, hips G and 7, ranges 11, 12, 13, 14, 15, 16, and 17, on 

 the waters of the Cadron and Point Remove creeks. They are the same
