the deeper the VelnS are IOuOWeC, lhe rlcHCr they will become; more especially when they reach rocks more favorable for the reception of ores.
 The analysis of two samples of lead, from the Kellogg mines, gave the following result: No. l, bright crystalline looking ore gave, by .reduc- ton, Sl.7 per cent. of metallic lead. By cupel- lation, this lead gave silver bead weighing l.06 per cent. of the lead employed, which is equal to 339.2 ounces of silver in ton ot 1000 pounds.
 No. 2 porous fine-grained ore, with particles of tale disseminated, gave 73.45 per cent. of metallic lead; this, by cupelIaton gave 0.1 per cent. of silver, equal to 224 ounces in a ton of 1000 pounds.
 The silver-lead ores of Great Britan and Ireland, worked in 1852, according to Mr. Hunt, las quoted in Whitney's Metallic wealth of the United States), ; ranges as low as ounces of silver in ton oflead; the highest, being that of Devon, contains 40 ounces of silver in ton of lead. The Cardig iganshire and Montgomery shire lead ores sometimes contain as much as 75 or 80 ounces of silver to the ton. At Wild berg, in Prussia, the lead contains so ounces ot silver to the ton. The slver-lead of the Upper lIartz, belonging to Hanover, contains from Is to l23 ounces of silver to the ton. From 70 to 80 ounces of silver is obtained from ton of
  From this it will be seen, that the sver-lead from the Kellogg mines greatly exceeds m rich ness the silver-lead ores of Europe and Tn the comparison, leaves margin for prohts so broad, that no doubt can be entertained ot the practicability of working these ores, not only for the lead, but the silver.
 Why these mines have been so long abandon ed, after having been once partially worked, l was unable to learn. The situation is highly favorable for rich lodes of metal not only silver lead but also copper.
 If the property, belonging to these mines, can be obtained on reasonable terms, and judic- ious and economical system of mining institu- ted, there can be but little doubt of a profitable result The stratum of argllaceous shale IS easily mined, and there is no difficulty in sink ing shaft through it. From the increasing thickness of the shale to the southeast, it IS difficult, at present, to state, exactly what the total thickness of the shales on Kellogg creek may be- before reaching the limestone; it may, probably, be 5000 feet or upwards.
 NEWTON COUNTY.
 Lead ore has been found in several places in Newton county, as Big creek and other branches of the Buffalo and Hudson forks of White river but the only attempt at tracing this ore to its origin in the rock formations, was dertaken near the line between sections l and 2 of township l5 north range west, not far from the mouth of Cave creek, adjoining Hills mill-tract -@rsAt this place Jesse Cunt explored for lead ore and finally sunk shaft of forty five feet. He Fobtained some 60 to 70 pounds of lead ore, but finally abandoned the prospect. He might have been more successful, had he made search in the calcareous rocks that lie higher in the adjacent hills, instead of prospect ing as he did, over the platform of sandstone which form the base of the bluffs on this part of the Buffalo fork of White river.
 In the southwestern part of Newton county, on section l6, and 35 or 36, township l6 north, range 23 west, on the waters of Buffalo river, considerable amount of digging has been done for lead, and some l8000 or 10000 pounds of the ore have been taken out. Great excitement prevailed about the discovery of ore and all the land in the vicinity was immediately entered.- It is thought, however that the richest deposits exists on the l6th section. At Clarks dlggings, where the ore has been principally mined, the lead is represented as lying in pockets or creyi ces in the rocks, and not in regular veins. This is the condition in which the ore is also found at Granby, in Jasper county, Missouri, the rich est lead mines in the West. Not only from the manner in which the ore occurs in the rocks of Newton county does it resemble the Granby mines, but it also has the same geological horl zon, and is accompanied bythe same association of minerals.
 The specimen of lead sent to the laboratory, by George Lewis, to be examined for silver, from Favettevlle Washington county, was from Newton county. Unfortunately, he did not state the exact locality from which it came otherwise, region thus rendered interesting, would have been thoroughly examined. As it was, we did not even learn the abundance of lead raised at these mines, until it was impossible to spare the time necessary to visit them. From what Is known Of the surrounding country, and the in- formation obtained from those who have been at the mines, there is every reason to believe that valuable deposits of ore will be found in this county.
 It is a fact worthy the special attention of those residing in the northern counties of Ar kansas, that there is every probability of find ing valuable deposits or veins of lead i'll the fol- lowing counties: Randolph, Lawrence Inde pendence Izard, Searcy, Marion, Carroll, New ton, Madison, Benton, and Washington. The occurrence of lead was already noticed in the former report. Since the publication of that report, however, 1t has been ascertained that granite makes it's appearance at the mouth of Spavinaw creek, in the Cherokee country, some thirty or forty miles west of the Arkansas line; and the probability is, that this granite under lies the lead bearing rocks in the north western counties of this State, and the south western counties of Missouri. A favorable bottom-rock is thus formed on which the ore may collect, thus giving plausiblity to tue opinion, that in some localities, by pursuing the irregular sur face lode of lead down to this granite, ore may be found in paying quantities.
 MADISON COUNTY.
 Some lead ore has been found in the Moudey settlement, about four miles noth of Huntsville; if 1t had its origin in this formation, 1t IS To- calty which should claim the attention of the miner, as will appear more fully in the next section, when treating of Benton county.
 BENTON CoUTY.
 The first and second members of the prece ding section, are of the same age and compost ton as the lead bearing formations of the Gran, by lead mines, in Newton county, Missouri; and there is every reason to believe, from analogy of structure, both in the rocks and general sur face of the country, that here, in Benton county, as we'll as in the northern parts of Madison, Washington, and western part ot Carroll county, discoveries may be made of lead deposits, similar to those of the Granby mines, in Miss ouri; therefore, it may be well, in this connec- tion, to record some of the facts connected with the mode of occurrence of the lead ores in these mines, which IS, in many respects, peculiar, and particularly worthy the attention of the inhab itants of northwestern Arkansas; since it may be the means of leading to discoveries that may not only enrich the owner of the land but develop the mineral resources of the coun-
