THAT TYPOGRAPHICAL MAP
The Scope of the Proposed Work
Outlined.
The State Asked to Join With the
Federal Bureau.
A Statement From the Members of the
United States Geographical Sur
vey--value of the Map
to the State.

Mr.. Arthur P. Davis, OF the United
States geographical survey. was called
upon yesterday by HERALD reporter,
and asked in reference to the proposed
Typographical charts of the state, in
which work the general government is
now engaged, and in which the state is
invited to cooperate. Mr.. Dsvis
stated:
"We are now engaged in making
geological surveys for the government,
and at present are doing work in Little
Bear valley, San Bernardino county.
The main features of our work show the
contour OF the country, hills, valleys,
ETC., but will not be so minute unless
the state co-operates, bearing half OF
the expense. There are 100000 square
miles of territory in the state, of which
10000 square miles is valley area. The
government work is confined to the
mountain areas, and if the state CO.
operates it will be extended to and in
clude the valley areas. But if the state
does not do 30 our work in the valley
areas will be on a much smaller
scale and merely for geographical pur-
poses. notice that the several state
universities have appointed committees
of conference, and at recent meeting
those committees decided upon a line
of work, and if the state adopts the re-
port, and makes the appropriation, the
work will be carried out on these lines"
The details of the work are:
I. That it be complete contour topo-
graphic map, constructed by plane-table
survey, based upon triangulation and
leveling, showing in addition to the
natural features:
Q) The location of all township and
land grant corners wherever monuments
of the same are in existence.
(2) All railways, canals and public
distributing bitches.
80 All public roads and roads which
are virtually public by being in unres-
tricted use.
a. All county boundary lines.
(5) All cities, towns, villages. ham
let's, mines and important places, to-
gether with dwellings and public build
ings which are outside of town limits,
in such a way as to render the map
practically useful.
(6) Within every township at least

the precise altitude.
II. That all contours be on scheme
involving intervals Of feet or multiples
of feet, according to the slope of the
ground, and that wherever the slope is
less than 15 feet per mile the contour
interval be feet, and be determined
by actual leveling of the contour lines.
Ill. That all navigable streams and
important water courses be located from
actual surveys.
Nv. That salt marsh land and fresh
water swamp land and overhowed lands
be distinguished by two distinct con-
ventions, and be located without refer
ence to the legal segregation lines.
V. That the field scale of the map be
not less than one and one-third inches
to the mile, and that there be at least
three triangulation points for each plane
table sheet.
V. That the publication scale be
162,500.
vii. That the size of the atlas sheets
be determined by the even Is minute
lines of latitude and longitude.
VIII. That the United States Coast
and Geodetic survey be requested to fur
nish as many triangulation points as
possible for the proposed survey.
TX. That headquarters for the survey
WORK shall be in California.
x. That the work shall be carried on
under the supervision of q commission
of five persons representing the state of
California, of which four persons shall
be appointed by the governor of the
state, one on the nomination of The State
university, one on the nomination of the
Leland Stanford, jr., university, one on
the nomination of the State Agricultural
society, and one on the nomination Of
the State Mining association, the fifth
commissioner to be chosen by the 9TH
ers 80 appointed.
XI. That the expense OF the survey be
equally divided between the state and
federal authorities.
XII. That the United States geologi-
cal survey engrave the Typographical
maps on copper and that the state OF
California shall have the privilege OF OBJ
tanning transfers or electrotypes OF each
sheet for it's own use.
''No doubt the matter will come up
before the next legislature, "con-
cluded Mr.. Davis" and an ap-
preparation of $25, 600 asked for, which,
with $25,000 from the general govern
ment, will survey about 1000 square
miles. It will take about 10 years to
complete the entire work, and the state
will be asked for $3.50, 900, or $25 900 a
year, and the general government would
make like appropriations. 1t is pro-
posed to distribute the maps free to
those interested in the development of
