description of lands, already spoken of, in the south-east part of Pope 
county, and have been derived from the same geological formations. 
PULASKI COUNTY, 
North of the Arkansas river, the stratigraphical character of the rocks, 
in Pulaski county, is very much the same as that previously noted, in the 
counties laying to the west. The millstone grit still forms the capping to 
the highest hills, while the cuts in the valleys have laid bare the reddish 
and dark underlying shales, which seem to augment in thickness to the 
south and east; while the sandstones of the millstone grit appear to 
become more schistose in structure. 
Imperfect crystals and veins of amorphous milk-white quartz have 
ramified the strata, close to the junction of the sandstones and shales, 
near Mr. Irvin’s, and not far from the stage road leading to Little Rock, 
where the adjacent walls of sandstone and shale are metamorphosed for 
18 inches on each side of the veins, but especially on the south side, where 
the wall is slaty and micaceous. The whole strata, through which the 
vein runs, are so much disturbed that, for a width of fifty feet, they dip 35 
deg. to the north east, with a north-west and south-east strike. Beyond 
this, the strata gradually assume a more horizontal position. No mining 
explorations have been made along the line of this vein, in search of 
metallic ores; though I believe the conditions under which the vein 
appears, favorable for discoveries. 
The hill at the toll-bridge, on Palarm creek, is 220 feet high, measured 
from the bridge floor, which is about 30 feet above the bed of the creek. 
The rocks of which this hill is composed, are thin-bedded, soft, brownish- 
colored sandstones, dipping about 40 deg. north-east, and intersected with 
veins of milky quartz. On the surface of some of the sandstones, quar- 
ried out to improve the road over the hill, clusters of transparent crystals 
were found attached. The upper part of this quartz-bearing sandstone, 
which caps the hill, is a coarse-grained, reddish rock, which crumbles 
easily to sand. 
About two miles west of Winfrey’s old stand, a remarkably hard, black 
metamorphic rock, in semi-crystalline blocks, traversed by numerous fine 
veins of white quartz, crosses the road. It is one foot wide, and dips 
about 35 deg. north-east. The strata, on each side of this tilted band, 
appear to be nearly horizontal. 
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, and known as the “ Kellogg lead mines.” The principal
