eastern part of Randolph. The “Buncomb ridge” may be especially ~ 
cited for its productiveness; and, being more elevated than the adjacent 
land, is not subject to overflow. 
The timber on the highlands, with the exception of the pine ridges, 
where the sandstone prevails, is a thin growth of stunted oak. On the 
bottom land, the growth of timber is large, and comprises white, black, 
red and postoaks, gum, hickory and black walnut. 
JACKSON COUNTY. 
The northern part of this county, examined by me as far south as the 
town of Jacksonport, on White river, is entirely destitute of solid rock. 
The geological formations are those earthy deposits, such as usually con- 
stitute alluvial lands. The low ridge, dividing the waters of Black river 
and village creek, is composed as follows: 
Siliceous soil and subsoil. -+--- se eeeeeecenecvees 7 feet.

25 feet. 
These are underlaid by a light-colored sand, the thickness of which 
could not be seen; this sand forms the substratum, which affords unfailing 
supplies of good water, and is reached by sinking wells, at a depth of 
from 15 to 30 feet. From the qualitative chemical examination, made of 
this water, taken from Mr. John Robinson’s well, two miles north of Jack- 
sonport, it was found to contain 
Carbonic acid, 
Bi-carbonate of lime, (small quantity), 
“ magnesia, ‘“ ae 
Sulphates, a trace? 
The exa‘nination of this water is important to clear up the prejudice of 
those persons, who have looked upon the well water of this portion of 
Jackson county, as deleterious to health. It contains the usual mineral 
ingredients of hard spring water; these, when not in quantities so large as 
to produce medicinal effects, cannot be looked upon as injurious to health, 
since they contain elements essential for the growth of the body, in a form, 
easy of assimilation. 
The northern part of Jackson county contains a large amount of highly 
productive land, easily cultivated, and especially adapted to the growth 
of cotton, wheat, oats and corn. A set of the alluvial soils of Jackson 
county were collected for analysis from Mr. H. J. Dowel’s land, section 32, 
township 14 north, range 2 west, fourteen miles north of Jacksonport;
