DIGEST OF GEODETIC PUBLICATIONS ISSUED BY THE UNITED STATES
COAST AND GEODETIC SURVEY RESULTING FROM SURVEYS IN THE
STATE OF OREGON.
The branch of the Government now known as the Coast and Geodetic Survey was
authorized by act of Congress in 1807, under the administration of President Thomas
Jefferson. From then until the seventies the work of the bureau was confined almost
wholly to surveys of the coasts of the United States necessary to produce nautical
charts. To fix the geographic positions for these charts, it was necessary to establish
points of control, and, incident to this, geodetic surveys were made of the east and
west coasts of continental United States. These included base measurements, tri-
angulation, astronomic observations, leveling, magnetic observations, etc.
In 1871 the duties of the bureau were broadened to include the making of geodetic
surveys of the interior of the country which should serve to connect the triangu-
lation on which the coast charts of the Atlantic and Pacific coasts were based, as well
as to establish a geodetic control for mapping and surveying projects in the interior
of the country, and in 1878 the name of the then Coast Survey was changed to Coast
and Geodetic Survey.
In the interval between 1871 and the present time this work has extended in some
of its branches to every State in the Union. While these surveys serve as the frame-
work for large mapping and surveying projects throughout the country, as well as to
determine State and national boundaries, there is no reason why the data resulting
from them when the points are within available distance should not be used for local
projects. Indeed, economy of effort in making local surveys will follow if advantage
is taken of previously established standard points of control because they are basic,
and where local surveys intervene between these standard controls there is a check
on the accuracy of the local work.
In mapping a small area of the earth's surface a high degree of accuracy is not gener-
ally attempted in establishing the geographic position of the initial points. The
result is that where it attempted to join several such small maps together into a homo-
geneous whole it would be found that there was a certain degree of inaccuracy which
would result in overlaps, gaps, and offsets. This is a problem that is often met where
independent small projects are undertaken to be joined later into a continuous map.
The reasons are that the areas covered are small and not coordinated to a scheme of
triangulation embracing the whole country. Similar difficulties follow where small
leveling projects are based on independent and arbitrary datums. In addition to
the gaps and overlaps that develop when areas independently mapped, each based
on local and generally arbitrarily selected controls, are joined together there is a more
serious outcome, in that positions must be recomputed from time to time as adjustments
are made and different arbitrary standards are adopted until finally a proper standard
is developed.
The purpose of this leaflet is to make available to those engaged in local surveying
projects and others the results of the standard data established by the Coast and
Geodetic Survey, so there will be an economy of effort in carrying on local surveys
and saving of expense in their recomputation at later dates. For the reason that the
systems of triangulation and leveling by the Coast and Geodetic Survey extend over
wide areas, the publications containing these data are not confined to any one State
in the Union, but generally contain results for many States. To get this information
in compact form, this leaflet has been prepared. It contains a digest of the work of
the bureau in the State of Oregon. In it are shown the places where observations
have been made and, by tabulation, the publication of the bureau containing the

results. It is not the purpose to present in this paper an exhaustive citation of all
the uses to which these data can be put. Their uses are obvious to the engineering
profession, and therefore the main purpose of this summary is to make known their
existence and how and where they are available.
TRIANGULATION.
The advantages of determining the positions of even farm and ranch boundary
monuments by triangulation are not, it is believed, fully appreciated. However,
they are obvious when it is considered that the exact positions of such monuments
can be redetermined by triangulation though the monuments be absolutely destroyed.
This is not necessarily true of boundary monuments that depend for their redetermi-
nation on the continued existence of the stones, trees, stumps, etc., that mark them.
While the initial cost in most instances, where standard data are within available
distance, of basing even farm and ranch surveys on points established by triangulation
connected with standard controls would possibly be greater than to base them on
natural objects determined only by compass bearings, the assertion is ventured with
confidence that the ultimate cost would be much less if we take into consideration
the necessity for surveys from time to time and the uncertainty resulting from ina-
bility to relocate lost corners, with consequent litigation costs, etc. Triangulation
stations of the United States Coast and Geodetic Survey on the coast and in the
interior of the country are used more and more in controlling maps and surveys, and
also as monuments in private-property surveys. The latter is especially true in the
State of Massachusetts. The increased use of triangulation stations for this purpose is
urged upon engineers and surveyors in work involving the location and perpetuation
of private-property lines or boundaries.
the
ELEVATIONS ABOVE MEAN SEA LEVEL (PRECISE LEVELS).
With the increased demands for accurate topographic maps of the country,
wonderful extension of our good-roads movement, the extension of the railroads, and
the development of river, irrigation, canal, and drainage projects, the net of precise.
leveling that has been partly extended over the country by this bureau affords bases
for local projects that it is feared are not fully known and taken advantage of by
those interested.
There are in most States of the Union lines of precise levels that are determined
with the highest degree of precision. These are all based on the same datum plane
(mean sea level), and where they are within available distance to use as the standard
for local leveling projects enable the local surveyor to base his elevations on a standard
datum and afford an invaluable check on the local work if it intervenes between two
or more of these standard leveling bench marks.

VARIATION OF COMPASS.
All civil engineers are familiar with the use of the surveyor's compass, but many
are not aware of the fact that this bureau has made a magnetic survey of the United
States, which includes the determination of the magnetic declination (variation of
the compass) at nearly every county seat in the country. The true meridian has been
marked at many of these stations, and at all of them the true bearings of several
prominent objects from the station have been determined and recorded. All users
of the surveyor's compass should determine the compass correction at least once a
year at one of these stations. To reestablish old boundary lines run originally by
compass, of which the boundary marks have been lost, it is necessary to know the
change in the magnetic declination between the date of the original survey and the
resurvey. As a result of its investigation this bureau is prepared to supply information
on this subject from the date of the earliest available observations to the present
time for any locality in the United States.
3
PUBLICATIONS.
The data resulting from the geodetic surveys by this bureau in the State of Oregon
are contained in numerous publications that have been issued by this bureau. To
enable an intelligent selection of a publication containing data of local interest, the
counties of the State of Oregon are listed in alphabetical order, and by a tabular ar-
rangement are shown the publications containing the triangulations and leveling
data for the State of Oregon and the pages in the publications where the data will be
found.
TITLES OF PUBLICATIONS.

""
In the tabulation that follows the titles of the publications are at the tops of the col-
There is one publication entitled "Special Publication No. 18" that contains
all the elevations above sea level (in feet and meters) of stations in the State of Oregon
(at the head of the first column) and the same publication contains descriptions of
the precise level stations in Oregon; there are four publications that contain all the
triangulation data for the State of Oregon, entitled "Special Publication No. 13,
"Special Publication No. 31," "Special Publication No. 74," and "Special Publica-
tion No. 84." For example, if an engineer is interested in the elevation and descrip-
tion of the precise leveling station at Baker City, Oreg., in Baker County, he will
turn to Baker County in the alphabetical arrangement of the counties, and the tabula-
tion shows that the elevation of this station is shown on page 132 of Special Publica-
tion No. 18 and that its description is found on page 179 of the same publication.

¹ Magnetic observations have been made at the places indicated above by the asterisk. For fuller infor -
mation see note following.
NOTE.-The descriptions of the magnetic stations that have been occupied by the Coast and Geodetic
Survey in the State of Oregon are contained in so many different publications of the bureau that it is im-
practicable to tabulate them as has been done in respect to the triangulation publication. However, the
tabulation does show in what counties magnetic observations have been made and the stations occupied
15
permanently marked and the name of the place in the county. Due to the fact that the magnetic decli-
nation is subject to change, and it is therefore impossible to keep the information in printed publications
current in this respect, it is probably just as well for those interested to ask for the description of the partic-
ular magnetic station in their locality as well as the magnetic declination (variation of the compass). The
latter can be given with a high degree of exactness. Besides the permanently marked magnetic stations
in the counties as listed in the foregoing tabulation there are in some of the counties auxiliary stations where
observations have been made in the investigation of areas of local disturbance, but which have not been
permanently marked. While the stations are not shown in the above tabulation because they are not
permanently marked, the results are on record in the archives of the bureau and readily serve as data for
deriving the magnetic declination at that point for a given date. For this reason, when making request
for magnetic data from the bureau, it would be well to state precisely the point and the date for which they
are wanted.
Furthermore, by interpolation, the magnetic declination can be given for points other than
permanently marked or auxiliary stations occupied by this bureau in the State of Oregon. We are espe-
cially anxious to serve civil engineers and surveyors of the country in respect to this branch of engineering.
We have made extensive magnetic observations and have comprehensive information regarding the
subject, so that there are but few points in the country for which information can not be given from this
office regarding the local magnetic declination and secular change.
The foregoing applies to geodetic publications issued by the Coast and Geodetic
Survey. Necessarily, in making geodetic surveys and extending this specialized
branch of engineering the field engineers of the bureau encounter and solve many
problems that are common to surveyors throughout the country. The solution of
such problems has no place in this paper. Many of them are contained in publica-
tions issued by the bureau. The matter is mentioned herein to indicate the desire
of the bureau to be of any possible assistance to the engineering profession along its
specialized lines of activity, and where such problems are brought to the attention
of the bureau all possible assistance will be afforded. Such inquiries are welcomed,
as it is the desire of the bureau to be of the greatest possible use to the engineering
profession, especially those engaged in surveying and allied branches.
It is the purpose eventually to prepare one digest of the geodetic publications of
'this bureau for each State in the Union. Including this one, digests to date have
been made and are available for distribution for the following States: Alabama, Arkan-
sas, Colorado, Florida, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine,
Massachusetts, Minnesota, Missouri, Montana, Nebraska, Nevada, North Dakota, Ohio,
Oregon, Rhode Island, South Dakota, Texas, Utah, West Virginia, and Wyoming.
Inquiries regarding any of the matters presented above should be addressed to the
Director of the United States Coast and Geodetic Survey, Washington, C. D.
NOTICE.
The
The Coast and Geodetic Survey maintains a field station at Seattle, Wash.
station is at present in room 202 of the Burke Building, Marion Street and Second
Avenue. It is in charge of an experienced field officer of the bureau. Among other
things, the purpose of this station is to permit more direct contact with the public
and to enable closer cooperation with other branches of the Government service.
The officer in charge will cooperate to the fullest extent possible in supplying informa-
tion or rendering assistance to those to whom this bureau can be of service.
