GEOLOGICAL RECONNOISSANCE 



mines are in township 3 north, range 11 west, and about ten miles north 

 of Little Rock. When first discovered, these mines created considerable 

 excitement, and the right of mining was leased by the proprietor of the 

 land, Mr. Kellogg, to a company, who were to hold this right so long as 

 they paid him regularly a stipulated amount of the ore. Some forty or 

 fifty tons of this ore were mined and shipped to Europe, for the purpose 

 of ascertaining its value. ]\o account was ever received, at the mines, 

 regarding the sale or disposition of this shipment of ore; and the company, 

 vt -e means were limited, becoming involved in debt and discouraged, 

 finally abandoned the enterprise. 



From long disuse, the shafts from which this ore was raised, have 

 become filled with water, rubbish, earth and rocks, washed in or detached 

 from the mouth of the pits, so that there is no opportunity, now, of inspect- 

 in * the condition of the ore in place. In giving an opinion, therefore, in 

 regard to these mines, we have to judge from the material thrown out, 

 from the general geological structure of the country, and from information 

 derived from Mr. John W. Purdom, who lived close by the mines at the 

 time the ore was mined. It appears that the ore "was found, not in a 

 single vein only, but occupying a number of veins, which traverse the 

 argillaceous shales under the millstone grit at this place; these seem to 

 • very much the same distribution and relation, as those previously 

 mentioned as occurring on the property of Dr. Lewis, at the Bull moun- 

 tain, in the north-east part of Conway county, as well as those observed 

 near Mr. Irvin's in this county. 



To convey a clearer idea of their geological relations, I subjoin the 

 annexed vertical diagram; which illustrates not only the succession in 

 Pulaski county, but also in Conway county:

the section, occupies the 

 [highest position, not on- 

 ly in the hills adjacent 

 to the mouth of Palarm 

 bayou, and in the ridge 

 dividing the waters of 

 that stream from Kel- 

 logg's creek, in Pulaski 

 count}', but also in the 

 Bull mountain, in the 

 north-east corner of 

 Conway county.
