Number 17 is from a plantation near Boon Hill, Wayne county, (At- 
kinson’s.) The soil is black, produced well for several years, and then 
began to fail, — to french in patches, which gradually widened until they 
occupy a large part of a field, fiat, low and swampy, and of the same 
general appearance and natural growth as number 18, which is from the 
plantation of Jas. Murphy, on Black River, New Hanover county. The 
latter sample was obtained from a barren patch of a few rods, in the 
middle of a large field, which had a number of such scattered over it. 
The field had all produced alike well for three years, and then began to 
fail in this way. The soil was dark brown to black, 3 to 5 feet deep ; the 
original growth, poplar, tupelo, white and red bay, maple and a shrubby 
thicket. No. 19 is a similar grade of soil from the lands of J. Foy 
near Polloeksville, Jones county. This, as well the others, contains in 
good proportion most of the elements of fertility. 
It will be seen that the analyses do not reveal the source of the diffi- 
culty, perhaps for the same reason suggested in regard to number 7. 
This is a point deserving further investigation and more minute chemi- 
•cal analysis ; especially since there is a considerable area of this descrip- 
tion of land.
