Globe 70 Be Divided Into l..
842 Sections; Result Of
Years of Effort.

SAW WASHINGTON, Oct. 4.-Uncle sam 10
slowly progressing on a new map OF
the coaMtry, to be q part of a new
world map, based upon n simple sys-
tenn proposed by American represent
atives In 1905, and accepted ut inter-
National conferences. 1t will be the
result Of years OF effort by map max
era who have desired a system OF
cartography whereby the same scale
Of distances could be used In q world
map, with lettering n symbols uni
form. The American map. Ii expected
to be completed in ten or twelve years.
Each country will map the terri
tories and waters under its own jurls-,
diction, and the geological survey OF
the United States interior department
IL making the maps Of this country.
Tho globe is to be divided into 1912
sections. Each section is designated
tby q distinctive letter and number
combination in addition to q name de-
rived fromAthe locality mapped. Each
sheet, covering one section, will Y
six degrees of longitude and four de-
grees latitude. The sheets are num-
bered from l. to so, beginning Mt the
18oth meridian Of longitude, and
girdiing the globe to the eastward:
and are lettered from A to ", north
and south with the equator as a start
ing point. The north n south polar
regions are to be shown in circular
sections from the S8th parallel Of lat
itude. and lettercd z-North and T.
South.
Complete World Map.
The main purpose Of h interna-
tional map, which will be drawn on
the scale Of one to one-millionth, Ia
to furnish a complete world map OF
uniform drawing, thus obviating Diff
ferent scales, Of distances, and to en-
able map makers and readers of ev-
cry country, to understand III maps
Of every other, even though they do
not understand any but their own,
tongues. There will be shown only the
outlines OF land and water, with
depths of water and heights OF land:
stream and river systems. or drain
age, I'm the map makers parlance,
roads, rail and trolley lines, towns and
cities and contours.
While the scale, which is approx
mate1y sixteen miles to the inch, will
allow of very inclusive work. many
details Of small towns and streams
will be omitted.
To show heights and depths, a
scheme of hypsometric colors has
been adopted. This will grade from
Q very light green, for shallow waters.
to the familiar tints Of deep blue, for
the increasing depths of seas: and
from light yellow, for low countries
and valleys, to a deep brown red for
heights. Contours will be shown In
sharp black lines. at intervals Of 100
meters. The metric system was adopt
ed for all numerals, and high points,
peaks and mountains will be shown
in meters. Streams and rivers will be
shown In blue, roads in red, cities and
rail lines in black. The names Of fee-
lures will be shown in the color OF
that feature, to obviatc confusion.
The projection is based upon a mod
flied polycon!c system. wherein me-
ridians OF longitude are>all in straight
lines. The lines Of latitude will be
only slightly surviving on each sheet.
because Of the large scale. The sys-
tenn is Of advantage in the adjustment
sof adjoining sheets.
Political Boundaries.
As many political boundaries will
be shown as the density of the data
included permits. F'or instance, the
map OF the United States will show
state. county. reservation. land grant
and other land office ines. The con-
troll, that is, positions determined as
Economically and by t~riangulation, to
Insure drainage,
rivers. streams, creeks. swainps. caHr
ais and other water bodies, and cuf-
ture. that is, towns. cities, railways,
roads and highways all constitute a
map" which Is compiled as the
f1rst step in the work and which will
be friade available by the survey for
state n other maps. The completed
map, IN size about 80 by 20 inches, is
copper engraved in the most delicate
and strong detail. and will be avail
able at the survey. It Is reduced in
size to form a scale Of eight milcs to
