                            DUNE SAND
  tun  a d isig4ay, loose, porous, wind-blown sand or fine sand to
a depth of 36 rmore inches. It is mapped mainly in a narrow strip,
rhng~i~i~i~idth fiom a few rods to nearly half a mile, on the shore
of Lake Michigan.ý The relief is hummocky or billowy. The soil
is gendiraly barren but in some places is covered with a sparse growth
of sand grass. Some of it was at one time covered with white pine.
This sand is too sterile to be of any value for farming. None of it
is cultivated.
                           SUMMARY
  Manitowoc County is in the east-central part of Wisconsin, bor-
dering Lake Michigan. It comprises an area of 590 square miles,
or 377,600 acres. The land surface ranges from level to rough and
hilly. The most conspicuous feature is the Kettle Range, a glacial
moraine crossing the county from southwest to norheast. The
highest elevation in the county is about 359 feet above Lake Michigan.
Drainage is all into Lake Michigan.
  The climatic conditions are favorable to the high development of
agriculture. The frost-free season at Manitowoc averages 162 days.
Inland the season is somewhat shorter.
  Manitowoc County lies wholly within the timbered region, and the
soils have developed under a heavy forest cover. The soils naturally
fall into two major groups, the mature soils and the immature soils.
The first group includes the well-drained upland soils and the better-
drained soils on old glacial-lake areas and alluvial terraces. These
soils are mapped in the Kewaunee, Bellefontaine, Fox, Plainfield,
and Superior series. The immature soils, which do not show a com-
plete profile, are mapped in the Genesee, Ewen, Wabash, Poygan,
Clyde, Maumee, Granby, Saugatuck, Bridgman, Coloma, and Longrie
series, and in the miscellaneous classifications rough broken land,
dune sand, and muck and peat.
  The agriculture of Manitowoc County is highly developed. Dairy-
ing is the chief branch of farming. American cheese is the chief
dairy product.
  The chief crops grown are hay, corn, oats, barley, alfalfa, and peas,
and some sugar beets, potatoes, and truck crops are produced. Poul-
try raising is rather important. Fruit is not grown extensively.
  The county is well supplied with transportation facilities. The
highways are for the most part well improved, most of them being
surfaced with cement, crushed rock, or gravel. All parts of the
county are supplied with rural mail service and telephones. Farm
buildings are substantial, well built, and usually kept in good repair.
  In brief, Manitowoc County is an up-to-date highly prosperous
agricultural community.
