   The SOILS AND SUBSOILs are from four counties only, viz.:
MIorgan, Nelson, Shelby, and Spencer, representing, respect-
ively, coal measures, upper Silurian, and upper Hudson river
formation soils.
  The six coal-measures soils from Morgan county, with the
exception of the virgin woodland soils, do not probably repre-
sent the best average soil of that region, having been collected
on the water-shed of the Licking river, where they have been
subjected to the leaching action of the atmospheric waters, or on
the bottom land bordering the stream. But they all may be
profitably cultivated under favorable conditions. It will be seen
that the subsoil contains less carbonate of lime than the surface
soil, also less of rocky fragments, and the old-field soils show in
every case a dimunition of the essential elements of fertility as
the result of continued cultivation.
  The Shelby county soils, except No. 2436, which is on the
upper Silurian formation, are located on the upper Hudson
river beds. Nos. 2430, 243i, and 3432 contain more than
the average proportions of all the essential elements of fertility,
and less than the average of sand and silicates, and should
therefore be quite fertile under favorable conditions. Numbers
