geodetic positions of primary triangu-
lati0n points. These furnish a per-
mancnt skeleton upon which TO extend
AN other surveys. Other permanent
marks. consisting of iron posts, cop
per bolts or tablets. are set to mark
elevations above sea level al points
not more than six miles apart. These
serve as datum points for further
spirit level work. for engineering in
v%estigatlons and for such public
works as canals, water supply, rail-
way and other public or private sur
veys.
These topographic surveys are exc
tremcly useful, In fact, almost essen
tial TO the development OF the coun-
try. New Mexico has thousands of
acres OF arid land. now bearing crops
of sage brush, that only need water
10 transform them into productive
farms. but In order TO reclaim this
arid land topographic maps must be
made 10 show their location, as well
as whore water may be secured To ir-
riEate the ame
For the development of the mining
interests of the territory II Is also es-
sential that the mountain regions be
mapped in order that the p%rospector
may have something on which Il
show the location of his prospect. the
distance of the same from lines OF
transportation, whore power may be
developed for the treatment OF the
ore. water secured FOR the stamp null
as wen as timber for the mine, n as
q base for a geological report ON he
district.
The water powers of the territory
are becoming more valuable every
year, and In order to develop them
maps pf large areas must be made In
order to determine the fan OF the
streams, to indicate the points where
power may be developed and TO show
the distance to point of utilization OF
The same.
In this s~eonnectlon. for the devel-
opment Of power, as well as for irri-
cation. 10 b. essential that the streams
be gagged in order that the mount
OF water that can be depended upon
may be known. and To secure reiia-
BILE data il Is necessary that these
gaugings be extended over a series OF
years. This part of the work Is in
charge Of the water resources
branch of the United states geologic
cal survey.
In fact. today the first thing asked
Tor before undertaking any enterprise,
i- Have YOU a mapg" Whether u be
railroad construction. irrigation, road
building. water supply. numbering or
mining. a map Is essential before the
enterprise can be undertaken prop
erly. a topographic map also shows
the feasible railroad routes through
the country. New roads may be laid
uut fairly accurately with but little
surveying. The map Is also useful for
educational. as well as military pur-
poses. Even the travelling man Is
glad TO have "A map of the section OF
the country through which he travels
l- Il shows him the most direct routes
from town 20 town without inquiry.
