HS UHlIeO states GoOlOSlCal sur
Vey is we'll represented in Arizona
this year in. the investigation of it's
mineral wealth resources. The out
put Of Arizona's mines constitutes an
important feature of the annual state
ments of mineral productions for the
United States, and each year geolig
lists and engineers are looking for
new facts to put into their reports.
Arizona, i'll common with other pub
lie land States, is getting a much
larger share Of attention from the
Geological Survey than some of the
older States of the East, OH account
largely Of the need Of information
for the classification OF the public
lands which is in progress. Although
little geological work has been done
in the State during the present sea-
son, it is expected that f. l.. Ran
some will visit the Miami and Ray dis
tricts next spring to complete the da
ia for his report Oh the geology Of
also do some reconnaissance work
with a view to the preparation of a
general report on the geology and ore
deposits of Arizona. This work, how
ever, will not be completed for two or
three years at the earliest. During
the winter F. C. Schrader will exam
| inc In lo of Ia n y
Indian reservation in order to class
ify them, for the Indian office. In
vestigations i'll Arizona, the field
work for which has been done but
the results Of which are not yet pub
! liShed, will lead to a report on the
ore deposits of the Patagonia and
der; a report on the geology and ore
deposits of the Tombstone District
by F.. L., Ransome; the Tucson folio
by G. f. Tolman, ..Jr.;. and the Ray
folio by F. l.. Ransome. .sz
| The work of collecting statistics
and information on the mining in
|
and semi-precious metal resources of
Arizona and reporting on new mia
| ing developments will be done By
! " c. Heikes, a statstician of the sur
vey, whose headquarters are in Salt
Lake City. The results of this work
will be published in the volume Of
Mineral Resources of the United
States for 1913.
Investigation of Water Resources.
The Water-Resources Branch of the
United States Geological Survey, in
cooperation with the State of Ariz-
Ona and others, is continuing it's in
vestigation of the water resources OF
the State. In connection, 19 gagine
stations are maintained on the Colo
rado river and tributaries in Arizona.
OF these, 2 are maintained in cooper
alton with the United States Recla-
nation Service; with the United
States Army Engineers; rs with the
State and 2 in cooperation with pri-
vate persons. At these gaging sta
tions the height or stage of the rivers
is determined each day by local obser
vers, and in some cases, by auto
matte cages and measurements of the
discharge OF the streams are made
by engineers Of the Survey when fea-
sible. From these data the quantity
OF water flowing past the various
stations is determined.
Records of stream flow in Ariz-
Ona are of particular Importance il
connection with the design, construc-
ton, and maintenance of power plants
and irrigation projects in investiga-
tions for the classification of the
public lands in the Carey Act investi-
cations. The records are much used
in solving problems involving a know
ledge of the quantity of water, such
as those relating to river regulation,
stream pollution, water storage, ,seep-
age, and municipal water supplies,
Hydrometie records are also of great
value for general statistical and com
parative purposes.
Examinations, investigations, and re,
ports needed by the Land Classifica-
tion Board of the United States Geo
logical Survey in passing on right
of way applications, water power with
drawals, and Carey Act segregations,
together with examinations of land for
designation under the enlarged home
stead act, involving the use of wa
ter, are being made by E. G. LaRue,
hydraulic engineer, Federal Building,
Salt Lake City, Utah, and E. C. Muir
