country lifetime,
A party OF ohioana who expected to
make a winter trip by automobile to
California consulted the topographic
maps Of the Survey and planned their
itinerary for the trip with the most
satisfactory and economical results.
Realizing from The maps that they
would travel at high attitudes and
would consequently encounter low
temperatures, they made detailed pro-
vision 10 meet every emergency. They
selected roads that followed the long
est levels, thcrhy saving trouble
and gasoline, not TO mention racking
delays.
Again, the topographic map was
consulted by New York business
man who wanted to hunt bear and big
game in the wilds OF New Mexico, and
who thus arranged his plans, with the
aid Of some correspondence, at dis
lance Of over 1000 miles. The ar
rangcments included even the details
Of the expense for the necessary pack
train for transporting his party and
supplies into country where tho
nearest postmaster to some points IL
As miles distant.
The forester depends on the Gov
ernmcnt topographic map to find
trails whereby his fire guards may
reach their "lookouts" in the season
when lightning sets fire tothe highly
inhammable pines and causes immense
monetary losses to the Government.
With the map also he lays out his tel
ephone lines and draws his permits for
leases to the cattlemen.
! A lumberman of New Mexico saved
several hundred dollars by purchasing
a l0-cent map Of the country in his
vicinity and using it to check up the
areas he held under lease. The copper
miner and the owner of turquoise
mine made fresh discoveries by study
ing l0-cent topographic map issued
by the Geological Survey.
The War Department saved much
time and expense by using Survey
map when those in charge Of Gov
eminent hospital for tuberculosis in
the Southwest desired to enlarge the
water supply The use of the detailed
topographic map was absolutely nee
essary in determining the limits Of
the drainage area, in deciding what
properties to purchase in order TO in
clude the best and strongest springs,
and in locating sites for dams and res
ervoirs. This work, done by trained
topographer with the methods now
employed by the Geological Survey,
reduced the cost very materially.
Fifteen cents spent by a reclama-
ton engineer in 1909-10 in connection
with private engineering project
saved his company $4,000 and estab-
lshed a project which would never
have seemed possible had not the
three topographic maps he purchased
given him comprehensive view Of
several hundred square miles of very
fiat country in Wisconsin, where the
drainage problems are most intricate
and delicate.
These are but a few concrete Illus
trations of the uses of the Geological
Surveys maps. Today topography is
being taught in the schools, and the
coming generation will more fully
appreciate the many values of such
maps. II is not unusual to hear the
boy or girl student discussing top
ography-the girl for its advantages
in selecting the most desirable botan-
ical expedition and the boy in plan
ming his "war game" with his fellow
cadet.
There is no limit to the possible uses
of the Governments topographic
maps.
