ored map of the state ; showing the several soil regions, which 
in this case largely coincide with the geological subdivisions 
as given on the map accompanying the report of i860. While 
the surface features of the state are given very much in detail, 
the geological description is considerably condensed, into one 
and a quarter pages ; since greater minuteness of description 
would have lain outside of the objects of the report. Hence, 
except as casually mentioned in connection with the surfaces, 
the geological observations made by Dr. Smith in 1870 and 
1871- remain unpublished, save as regards the abstract of his 
observations in the Yazoo bottom, given in the paper referred 
to before. 
A revised edition of the report of i860 would, without addi- 
tional field work, form a pretty complete account of the geolog- 
ical and agricultural features of the state.
