 Arkansas promises, also, to afford consdera ble lead ore, which occurs both in the magnetism Hmestones of lower silurian date, and in the sub carbonierous lmestones; also in the states ot the base of the milstone grit, where these border OF the confines of the granite region of Pulaski county.
 The lead ore in this latter position is rich in silver, probably more so than the argentiferous galena of Europe, which have been wrought to any extent. The only ore, which has been cu- pelled in my laboratory, that surpasses 1t in the Ter centage of contained silver, IS some of the steel-grey finely crystalline argentiferous galena from Nileport near Lozere, in France.
 Fragments of porous lead ore, picked up among the rubbish at the mouth of one Of the shafts in Pulaski county, yielded by cupelation from the reduced lead, at the rate of 224 ounces from the ton of 2,000 pounds; and specimen of bright, steel-grey ore, finely crystalline Tn its structure, from the same mines, obtained Tn Little Rock gave as much as 339.2 ounces to the ton of 1000 pounds.
 The cherty limestone, which underlies the barrens and praires of the northwest part of the State. promises to afford rich deposits oflead ore. as the geological formation Is complete counterpart of that around the already famous lead mines of Granby, in Newton county, Mis- souri.
 The lead region in the lower magnetism lime stones, bears more of the character of those in Fancy county, Missouri.
 PULASKI COUNTY.
 The most important mineral locality which has yet come under my observation, in Pulaski county, north of the Arkansas river, IS situated on kellogg's creek, known az the Kellogg lead mines" The principal mines are in twon- chi oOrtb l 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 pro- prietor of the land, Mir. Kellogg, to company, who were to hold this right so long as they paid him regularly stipulated amount of the ore Some forty or fifty tons of this were mined and shipped to Europe, for the purpose of ascer tainine its value. No account was ever receiv- ed at the mines, regarding the sale or dlspos ton of this shipment of ore; and the company, whose 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 inspecting the condition of the ore in place. In giving an opinion, there fore, in regard to these mines, we have to judge from the material thrown out, from the general geological structure of the country and from in formation derived from MT. 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 mum Der of veins, which traverse the argllaceous shades under the millstone grit at this place; these seem to have very much the same dlstrl button and relation, as those previously men, toned as occurring on the property ot Dr. Lewis. at the Bull mountain, in the northeast part of Conway county, as well as those observed near Mir Irvin's in this county.
 Here follows diagram which we cannot copy here. Dr. Owen adds:
 The lowest stratum(a) of this section com prses the shales forming the valley of Kellogg , creek, which are traversed by system of me tallferous veins, containing a rich silver lead, associated with quartz, tale, (tallow rock of the miners copper pyrltes, spathlc iron, blende. The principal veins have course nearly east and"west. At the Kellogg mines, metalfer- ous-yeias are found, occupying belt of country from north to south, of more than half mile, and the whole system of quartz veins and titled strata. of which the Kellogg veins from part, must have a width, in the same direction, ex- ceedng twelve miles.

In following the vein, this shaft twas carried l08 feet through lghales (a) of the section, after which the wofk was abandoned. The vein was found to contain more or less lead throuhgout ,be whole depth Another shaft, known as the (.
