at the north. A soil which might bear corn in Massachusetts 

 would not sustain it on the coast of North- Carolina, on ac- 

 count of the more rapid evaporation of water ; in conse- 

 quence of which, a plant would be early deprived both of 

 water and nutriment, though it might be found in the medi- 

 um in which it had been growing. 



CHAPTER IY. 



Soils of Jones county, taken from the plantation of J. H. Haughton, Esq. 

 Composition of a brown earth overlying and resting upon the marl beds. 

 Recapitulation. 



27. Several specimens of soil have been furnished me for 

 analysis from Jones county, which, as they may be employed 

 to illustrate the composition of the cultivated lands in that 

 section of the State, I Shall give the results in this place. 

 They were furnished by John H. Haughton, Esq., from a 

 plantation which he recently purchased. Four kinds were 

 forwarded, marked 1, 2, 3, 4 respectively. No. 1. Color, 

 brown or blackish brown, and to the eye appears rich in veg- 

 etable matter. When ignited it loses readily this part of the 

 soil and becomes a light drab, leaving a fine residue resem- 

 bling that of the Hyde county soils. Its appearance shows 

 that it is a silicious soil. One hundred parts gave me th 

 following proportions : 



Silex 82.300 



Peroxide of iron and alumina, 4.300 



Organic matter, 4.500 



Lime, 0.102 



Magnesia, : 0.02C 



Potash, 0.003 



Soda 0.001 



Water, 8.800 



Sulphuric acid, trace, 



Chlorine,., trace, 



100.025
