Tit Survey got It's "a to the ground
and hear6ened 70 the developments,
As soon as TouOpah bad assumed
definite dimensions, topographers
were on hand to trace It's llueaments.
A mining mp was made Of the Tono-
pah area. which showed all that
there was to depict at the time. Tue
town lies III a depression surrounded
by pleva tious. known now a. Butler
mountain. Mt. Oddip, I}roughpr
mountain, ARAFAT mountain and
Gold mountain, all volcanic necks,
whose gaunt outlines are drawn with
accuracy upon tine map
All the roads branching out from
Tonopah 10 the numerous outlying
camps are shown. Spriuklrd thick
over the surface Of the map are tiny
crosses. each one indicating a pro-,
pect hole. So useful has that map
been found that there IS now d de
mand for similar maps Of urighb0r-
Ing regions, where The prospects are
equally promising. In response 10
tins demand, the Survey will, accord
ing to the Mining World, send parties
into the field during the coming
summer TO make surveys for three
topograp hic maps.
Two of these pro. pective maps
will be detail maps and one will be IA
reconnaissance map. The detail
maps viii include one Of the Goldteld
area. which lies 233 miles south Of
Tonopah and was located late IN the
spring OF 1903, and one Of lhp Bull
frog district. which is situated about
so miles southeast Of Tuunpah, and
was only discovered IN 1904 The
Gold6eld MAJ will be drawn on a
scale of 2.00O feet to the inch and
will cover about 40 square miles ri
territory The Bullfrog may be
drawn TO the 5 me scale, but that Is
not vet definitely determined
Tie reconnaissance map, which
will take in Guldheid, near the north
west corner will cover an area l20
miles long by 80 miles wide, OF about
10000 square miles IN round numbers
to the south and east Of the runopah
district.
All the mountains aud bills will be
shown, with their approximate
heights and shapes, all the roads aHC
what is very important in this high
trepless desert. all the springs anC
water holes. This map viii take il
yart Of the famous Death Valley |
mas never been determined accurate
In. but il has been computed that tin
lowest point in the valley Is abou
4j1 feet below sea level. which woult
make IL the lowest point in til.
United States. Levels for the cou

carried from Mohave, under the d
rection Of NJ r II. Farmer.
The survey expects to put from
to 20 men on this topographic work
They viii start for the field abot
the middle Of May or the first
June

Edward Spur, who visited Touopa
as early as 1902 and made a tiyiu
"trip 10 Goldfeld the same yea
when it was known as the GraudI
district. He brought away fro
Fouapah numerous samples Of q
country rock, which he studied und,
the microscope during the followil
winter. In the summer Of 1903
made a thorough and systemat
study of the ore deposits Of Ton
pah The chief economic results

lions he published in the fall Of IS
in a preliminary report Bulletin \

has Just finished and il is now in
hands Of the printer. 1t will
