GEOLOGICAL OBSERVATIONS.

Mr.. JouS II. KLtPPARr, Secretary Of the State
Bari Of Agriculture, aud member uf the Ohio
GsOl'gical Corps, has male visit to the
great !" swamp rrginn," in the northwest of the
State, why're he made many valuable ohserva-
,ions. the result OF which may be briefly con
densed as follows:
The northwestern portion Of the Stats, from
DArke, Shelby aul Logan counties 10 the Mich.
igan line, and lrom Crawford aud Ottawa c,un-
ties to the Indiana State line, with rare cEcep.

annual suceulent plauts To- the massive forests
trees are all ot the species which require an
abantent supply of moisture, among the latter
s,eh a. beech, ash, hickory, elm, sycamore,
swamp oak. &c. The supply &c timber in THE
Tthwest is almost unlimited, the quality eX-
reilent, and more than all the kihd. are those in

are equal, IL not superior in value to the mineral
regions Of the southeastern portion Of the state.
