   The chemical analyses of eighty-three soils, from twelve
counties of the State, are given in the following detailed re-
port.   The limits of the variations of their several essential
ingredients are shown in the following table, viz:

  This table of extremes of composition shows wider limits
than  that of volume 1, and may be supposed to exhibit the
relative chemical composition of very good anid very poor soils.
Tlhe rich soil being characterized by larger proportions of
organic and volatile matters (within certain limits), causing
the soil to absorb alid retain much hygroscopic moisture (ex-
pelled at 2 12' F.); larger relative quantities of alumina. &c.,
&c., which    hold  more   water, &c., expelled at 3800 F.; but
especially  being   more rich    in  the available alkalies, !)otashl
and soda (particularly potash); by containing more phosphoric
acid, lime. &c.. and having less sand and insoluble silicates.
The poor soil generally contains a larger quantity of sand and
insoluble silicates and smaller proportions of the other named
ingredients. Exceptions occur to these general statements,
of course; for great excess of lime or magnesia carbonates,
