MANY NEW MAPS ISSUED.
Great Variety of Country Covered by
U. S. Geological Survey Engineers
Different Grades of Maps Produced.

A hundred new maps year are the
product of the big engraving and print
ing plant of the United States geological
survey at Washington. About two atlas
sheets q week are turned out in the
construction of the great Topographic
map OF the country The Is new sheets
added during the last six weeks to the
1900 now carried in the regular stock
show good examples of the widely differ
ent kinds of country covered by the
government topographers. The areas
mapped on these sheets range from the
high forested mountain region of Col
orado to the low, rich alluvial bottom
lands of Mississippi and Louisiana
lands valuable for mineral resources, and
lands rich in agricultural possibilities
beyond the dreams of avarice. For any
comprehensive development of these
areas the Topographic base map becomes
the first engineering necessity. The
scale OF the maps varies from ! inch
on the paper, representing half mile
of country, with contour interval of
only feet, for the Mississippi delta
lands showing very detailed survey
suitable for drainage base-to | inch
representing miles, with 100 foot con
tours, for the Castle Rock quadrangle,
Colorado-covering an area which does
not require such refined work
To Be Followed BY Geological Work.
The Castle Rock area contains coal
and Ignite and report on it will be
made later by the survey in the form
of a geologic folio; but the vicinity OF
Castle Rock is also famous for its po-
tatoes, which are comparable to the ia |
nous Greeley potatoes, and for other ag- |
ricultural products. The western por-
ton of the area includes part OF the |
Pike national forest, and for national |
forest administration the map affords |
an ideal base.
Three of the maps represent lands |
along Mississippi river in the Yazoo del |
ia; they show parts of the Moon lake |
quadrangle, the Hollywood tTunica coun-
tyl quadrangle, and the Lake Cormor.
ant quadrangle, all in Mississippi. These.
maps were made in cooperation be- I
tween the federal survey and the ITALIA
hatchie drainage commission of the state
of Mississippi, They are on the scale
of | inch to half a mile, with 5-foot
contour intervals, and show every slough |.
and swampy place and every inequality
of the area which must be taken into
consideration in planning drainage sys-
TEN that shall make these lands the
most productive in the United States.
Lands of Great Richness.
Farther down the river, in Louisiana,
similar areas have been mapped in CO.
operation between the federal survey
and the fifth Louisiana levee district of
the state of Louisiana, the sheets por-
traying portions of three quadrangles,
the Ashton bridge. MiIlikin, and Mill (,
kens bend-land built from the silt $
brought down by the great river and of
nearly inexhaustible fertility. Another
map of an area cut by the course of |
the Mississippi-the Milan quadrangle, q
country OF a different
character. Here at Rock Island the Fa- a
Their of Waters is less of problem. Il
This map was made in cooperation be Y
tween the federal survey and the state |
geologist of Illinois. The scale of this I
map is mile to inch and the contour t
interval 20 feet A still different contour D
feet-is that of the map 2
