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 AYhile 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 7 feet. 



Tough yellow clay 18 " 



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, " " 



Sulphates, a trace? 

 The examination 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. II. J. Dowel's land, section 32, 

 township 14 north, range 2 west, fourteen miles north of Jacksonport;
