Geological Surveyors
fit Work in Grant and Winn
Parish Territory.
Maps to be Prepared of Great
Value to the People OF
Louisiana.

veying party, supervised by j. w.
Bngley, will soon begin the task of
mapping, geographically, an area
of about 300 square miles near
Winfield, La. This work is done
by the United States Geological
Survey, largely in continuation of
work done by G. d. Harris, the
State Geologist. The maps result
ing from the surveys will be drawn
on scale of one mile to an inch,
and differences of elevation will he
shown for every change of twenty
feet in height.
Later in the season the same
party will continue the work which
was in progress last year in Baton
Rouge, Iberville and neighboring
parishes, covering about 600 square
miles near Baton Rouge, Donald
sonrille and White Castle. The
scale of maps drawn from this
work will be one mile to an inch,
and differences of elevation will be
shown for every twenty feet in
height. This work has been un-
-dertaken largely at the request of
the officials of the State Agricul-
tural Development Station and of
Representative Samuel NJ. Rob
ertson and other members of the
State delegation in Congress.
A party under T.. L. McNair
will be engaged in extending very
accurate primary surveys over por-
tions of Winn parish, with a view
to furnishing exact positions to
which to tie the public land sur
vey work and the topographic
maps, sosthat the whole may be
fixed properly in relative position
to county lines, town lines, proper
ty lines, etc.
Permanent marks, consisting of
metal tablets bearing the name of
the State and OF the Government,
aud the elevation, will be estab-
hshed at distances about three
miles apart. All lines of levels
run by the Typographical parties
will furnish datum upon which to
base any leveling which may be
done hereafter by railways, mill
companies, etc. Careful spirit lev
els will give the height of all val
leys and streams, of lakes and
ponds, and of hill summits. Every
rond and house will be indicat, d
on the mnps aud the shape of all
the hills Will be shown.
1t is believed these maps will be
of great value to the people of Lou
isiana in the development of the
States natural resources. They
form the base maps for Il 9 study
of the. geology aud for the W ,rk of
the Bureau Of the Soils of the De-
rartment of Agriculture. They
form basis for the development
of the forests and the gool roads
of the State, and are of great use
10 all public officials engaged IN
building reservoirs and water
works, as well as to engineers and
surveyors who wish to lay out and
construct electric roads and rail
roads. In time these maps will
doubtless be used in the schools as
the most accurate of atlas sheets
from which to teach physical ge-
ography.
Parties from the survey are now
engaged in making topographic
surveys in the neighborhood OF
Jackson and Florence, Miss, and
in portions of Simpson and Ran
kin counties. This work is done
under the supervision of Messrs.
j. w. Bagley. L. II. Moncure and
number of aids. 1t is expected
that au area of about 225 miles
will be mapped. These atlas
sheets viii be drawn OH n scale of
one mile to an inch, and will show
differences of elevation for every
change of twenty feet in height.
