LETTER OF TRANSMITTAL

June 1, 1938

To the Director

N. J. State Board ofConservation and Development

Trenton, New Jersey

Sir:

Attached hereto is a report which gives a brief statement concerning the New

Jersey Geodetic Control Survey which your Department has sponsored since the Sur-vey was operated as a Works Progress Administration project.

I have tried to give herein a short story of the purpose of the Survey, its organiza-tion and its accomplishments.

_> Small scale maps, copies of parts of the Atlas Sheets of your New Jersey

Geological Survey are attached, giving location of triangulation stations used andtraverses run between them.

There are further given recommendations and samples for connecting any surveywork with the Plane Coordinate System.

A publication of all results obtained is not desirable as it would be too expensiveand there would be no need for having information covering the State available inone book at this time, as much o_ the work is still incomplete.

The attached maps form a proper guide in the search for the information needed

by public agencies, engineers and surveyors _n any particular location in the State.

Respect fully submitted,

ARTHUR NOACK, State Supervisor

N. J. Geodetic Control Survey.


PURPOSE OF THE SURVEY

Accurate maps of large areas require a basic frame work into which the details can be fitted so

that the whole gives a correct picture of the relative position of all details shown on any map.

In the young days of our republic, there were no charts available showing harbor entrances andcoast lines. To alleviate this need the "National Coast Survey" was established by Act of Congress

in 1807. A Swiss mathematician, Ferdinand Hassler was employed to lay out the plans under which

this coast survey was later executed. He covered our coastal areas with chains of triangles with

side length of about 25 to 50 miles and computed the geographic positions, latitude and longitudefor each corner of these triangles. By topographic survey between these triangulation stations, thelocation of coastal lines were ascertained and plotted.

Later on this same method of triangulation was used in the interior for the location of State

boundary lines. The "National Coast Survey" was authorized to enlarge its field of activities and in1878 the "U. S. Coast and Geodetic Survey" was established. This survey began to run triangulation

chains or arcs with first order accuracy in both east-west and north-south directions about I00 miles

apart. To-day, although the whole country is not quite covered with a triangulation net, some sec-tions of the country have first order arcs much closer. New Jersey has been especially fortunate in thatit has several first order arcs with 150 triangulation stations, the latitude and longitude of which

were known and available to anyone who wanted to use them.

Unfortunately geographic positions cannot be readily used for a local mapping project or for any

local survey work. Their use involves too much costly field work and computation work which coun-

ties, municipalities and private engineering concerns could not afford.

The U. S. Coast and Geodetic Survey had never sufficient funds at its disposal to do any more

than first or second order triangulation work with all its other activities, such as astronomic work, ofirst and second order level work, observing and reporting tides and currents, investigating terrestrial

magnetism and gravity, seismological work and preparing hydrographic and topographic maps andnautical charts.

For smaller areas a plane coordinate system was recognized as the ideal basis for any survey work.But since neither the U. S. Coast and Geodetic Survey nor any other public or private agency were

able to undertake the establishing of such system, there was nothing done anywhere in this respect.

When it was found that due to the depression thousands of engineers throughout the country

were without work, the Federal Government decided to use these engineers through C. W. A. andlater on E. R. A. in the establishing of Local Control Surveys for areas covering a whole state, if

possible, and thereby prepare a common permanent basis for any future detailed mapping.

In t934, the mathematicians in the U. S. Coast and Geodetic Survey proceeded to establish plane

coordinate systems for the various smaller states or parts of the larger states. Such systems eliminatethe involved computations dealing with geographic positions for every day use and permit insteadthe use of plane trigonometry in connecting with them.

TYPE OF MAP PROJECTIONS USED

Due to the di_erence in area and shape, the map projection used for each state had to fit condi-

tions. Thus, where a state extends mainly from east to west and is quite narrow in the north and

south direction, the Lambert conformal conic projectlon with two standard parallels held true to scalewas used. For some of these states two and three overlapping zones were established; Texas haseven five. Where a state extends mainly in a north and south direction and is narrow in the east

and west direction, like New Jersey, the plane coordinate system is based upon a Transverse Merca-tor Grid.


NEW JERSEY PLANE COOI_INATE SYSTEM

In New Jersey, the plane coordinate system was legalized by an act of the Legislature known as

Chapter 116 of P. L. 1935, mainly due to the efforts of Professor Philip Kissam of Princeton, who

was then in charge of the Local Control Survey. This Act, the first one of its type in the United

States provides that the official survey base for the State of New Jersey shall be a system of planecoordinates on a transverse Mercator projection of Clark's spheroid of 1866 having a central merid-

_an 74°-40 ' west from Greenwich. For this meridian, the scale is set one part in 40,000 too small.This gives a correct scale on the small circles parallel with and about 28 miles distant easterly and

westerly from the central meridian. Beyond these small clrcles, the scale grows somewhat too largeso that the east shore of the State at 74°-west Of Greenwich shows the scale 1 part in 70,000 too large

and for the most western point of the State, Pcnnsville in Salem County, which is 75°-35 ' west ofGreenwich, the scale is one part in 20,000 too large. The act provides further that all coordinatesare expressed in feet, the X-coordifiates being measured easterly along the grid and the Y-coordlnates

being measured nortberly along the grid, the origin of the coordinates being the intersection of merid-

ian 74°-40 ' west from Greenwich and the parallel38°-50 ' latitude. Thls orlgln, however, is not zerofor both X and Y but has been given the coordinates for X:2,000,000 and for Y_0 feet. Thislatter feature and the location of the origin was used in order to avoid a change in sign in calculations

as this arrangement brings the whole State in one quadrant so that all signs are positive.

The U. S. Coast and Geodetic Survey has worked out a system and forms for the computationsso that the work of converting geographic positions into plane coordinates or the reverse has been

simplified considerably. Special Publication No. 195 of the U. S, Coast and Geodetic Survey gives

a full account of all steps involved and also gives examples.

The N. J. Act further provides that in any description of land, metes and bounds as-well asplane coordinates may be used.

ORGANIZATION

The Survey was organized in the latter part of 1933 as a part o1 the N. J. Civil Works Admin-

istration and was continued in May 1934 under the Emergency Relief Administration until October

1935 with Professor Kissam in charge, During the following month, the Survey was reorganizedunder the Works Progress Administration with the New Jersey State Department of Conservation andDevelopment as sponsor and under the direction of the writer.

There were field parties maintained in all counties of the State except Salem County where

qualified engineers were not available to take charge of the work. Under E.R,A. there were employed

double field parties of 9 men each under one party chief and in the larger counties two such field partieswere maintained. The average number of persons employed under E.R,A. was 300, while under W.P.

A. the average number of persons employed was about 190. There are now maintained twenty fieldparties for traverse and level work having from six to ten men and one field party for triangulation

work. The computation work is done in the main office with a staff of 12 geodetic computers and 8computers. The administrative personnel consists of a chief clerk, a timekeeper, an engineer in charge

of progress reports and maps, a stock-room clerk and four stenographers. The work was done firstunder the project known as State-l, tben continued under State-172 and is now operating under the

designation of 1916-O.

EQUIPMENT

For triangulation work the Survey had the loan o1 one 1" Parkhurst theodolite, one 5" and one10" theodolite, heliotropes, signal lights with dry batteries for nlght work, several 90 toot steel towers

and three collimators for centering instruments. All this equipment is owned by U. S. Coast and Geo-detic Survey. For traverse angle work there were available only instruments loaned by the State High-

way Department, Rutgers University, the Central Railroad of New Jersey and private sources. Mostof these instruments had only l' or 30" graduations. The lack in quality and refinement of this equip-ment had to be overcome by proper methods and an increased number of observations.


For chaining, the tapes used are 100 foot steel tapes with spring balances which were loaned inthe beginning by the U. S. Coast and Geodetic Survey. Each field party has two tapes which aretested once a month by comparison with two 100 foot Standard Invar tapes, also loaned by the U.

S. Coast and Geodetic Survey.

The testing of tapes is done on the Princeton University campus where the apparatus necessary

for standardizing tapes had been constructed in the beginning of the Survey.

All chaining is done over three-legged wooden stools. For marking, fine pointed pins are used.For sighting, field parties have built their own tripods to hold sight rods or targets in place.

For level work on first and second order runs, eight Fischer precise levels owned by the U. S. Coastand Geodetic Survey are available. For leveling of the heads of chaining stools, hand-levels were used

in the beginning which have gradually been replaced by the older Wye and Dumpy levels available.

For the marking of intermediate traverse point.sin rural sections where pairs of monuments are set

about two miles apart, _" pointed steel rods 18 inches long were used. In urban and suburban areas,all traverse points were monumented. All monuments set under C.W.A. and E.R.A. carry the in-scription "U. S. Coast and Geodetic Survey and State Survey". Under W.P.A. the monument in-

scription was changed to "Department of Conservation and Development, N. J. Geodetic ControlSurvey". Each disk gives the number of the monument and its elevation in feet above mean sea level.

MATEBIA/_

Sand, stone and cement for setting monuments were in most cases obtained from county or munic-ipal yards free of charge. Originally precast monuments, three feet long and six inches square on top

and 8 inches square on the bottom were used. Now all monuments are field cast.

TRANSPORTATION

Transportation of men, materials and equipment to and from work was furnished by using two

cars for each field party at current rates for mileage, verified by party chiefs. This transportation

item represents about 7.9 percent of the payroll. While this seems to be rather high, it must be remem-

bered that without sufficient means of transportation, the Survey would cease to function. In many

cases, county engineers, road supervisors and municipal officials assisted by furnishing trucks for thetransportation of materials and triangulation towers.

contribution except that of the cost of printing results obtained by this Survey.

The distribution of Federal expenditures at present is approximately as follows:

Payroll ...................... 86.9 % Survey equipment .............. 3.0

Travel expenses ................ 7.9% Office rent .................... 1.3e_Orifice supplies .................. 5% Telephone and other costs ........ 4%

In each county there is a field office, usually in a county or municipal owned building which is given

to the Survey free of charge.


WORK ACCOMPLISHED

The tabulation given on Schedule I shows the amount of work performed under C.W.A., E.R.A.

and under W.P.A. From this it will'be seen that to-date there have been set throughout the State

8,374 monuments and benchmarks along 2,522.9 miles of traverses. Coordinates for approximately4,400 monuments for horizontal control and elevations for about 4,000 monuments and 1,500 bench-

marks for vertical control have been computed and wherever possible adjusted and are available for useon public or private engineering and survey work.

USE OF RESULTS

Control Surveys are performed to supplement the primary triangulation system. They consist ofeither additional triangulation or of traverse work for the purpose of determining the relative posi-tions of permanently marked points on the surface of the earth. These positions are known interms of geographic position, latitude'and longitude and are available in that form from records of the

U] S. Coast and Geodetic Survey. Since 1935 triangulation stations can be given in both geographicpositions and plane coordinates: The positions of monuments set on traverses between these stations

are given in plane coordinates. The elevations of all stations and monuments and benchmarks above sea

level as well as all coordinates are available tothe public in the office of this Survey, 17 William Street,

Newark, New Jersey so that inquiries in Washington for such information are no longer necessary.

If the Survey is pennhted to continue there will be bulletins available published by the State De-

partment of Conservation and Development which will give descriptions, coordinates and elevations ofall stations, monuments and benchmarks now set. The work so far completed forms a skeleton whichcan be extended as needs develop from time to time.

The use of this information obtained by this Survey is manifold. Requests for information re-

garding horizontal control came in to the office since the start of the Survey in 1933 and have in-

creased continuously. Parallel with the Control Suryey runs another W.P.A. project, the Riparian

and Stream Survey which is to map all brooks, streams and waterways throughout the State.. With-out a Geodetic Control Survey as a basis, this mapping project would be impossible. Regional and

County Planning Boa.rds, County Ezlglneers' of/ices and County Park Commissions, most of theState Departments, the U. S. Resettlement Administration, the Department of Agriculture, Soil Eros-_on Service, the U. S. Army and Navy and numerous municipal engineers have requested and received

such information. In one case, this Survey has assisted in settling a dispute regarding County bound-ary lines between Atlantic; Camden and Gloucester Counties by establishing a new line agreeable tothe parties concerned and running traverses along and across the county line so that the new line could

be permanently fixed and monumented in the field by using N. J. Geodetic traverse points in the lay-out

of the new line. In another instance, this Survey furnished triangulation points and coordinates forend points of a long county boundary llne between Bergen and Passaic Counties and an azimuth so thatit is now possible to determine the location of this line in the field.

The most important use of the Control Su_ey data is made for property surveys. If the startingpoint given in any deed description is lost, if magnetic bearings are copied from old descriptions with-

out giving in the deed the year when these bearings were observed, if corner markers are destroyed,

willfully or by the elements, they always can be restored because their position has been permanentlyfixed if the survey and the description g_ves plane coordinates for property c_rners. With such con-

nection, the advice of the "oldest men" in town is not needed nor can there be ever a dispute overboundary lines once this method of controlled surveys has been adapted.

Observations of magnetic declination have also been made throughout the State.

READIUSTMENT OF 1937 BY U. S. COAST AND GEODETIC SURVEY

During the progress of this Survey, it was found that discrepancies existed between two parallelarcs of the U. S. Coast and Geodetic Survey. In order to clear up these discrepancies, the U. S. Coast

9


and Geodetic Survey requested that a first order base line about five miles in length be measured from

Elizabeth to Port Reading along a tangent of the Central Railroad o1 New Jersey. In addition to this

some first order triangulation check-up work was done between Princeton and Netcong. All observa-

tlons were made under the supervision of Lt. Lushene of the Coast and Geodetic Survey. As a result

of th_s work, all geographic positions of triangulation statlons in northern Jersey above a line from

Seaside Park to Mt. Holly to Newtown to Philllpsburg are now being readjusted. In most cases the

change is negligible so that coordinates could readily be used for mapping. However, since most of the

positions of the stations north oi the l_ne above described were changed, traverses connecting these sta-

tions have to be recompoted. Part of this work has been done and the result is that in all cases the

closure has been materially improved.

So, for instance, was the result for the first traverse in Bergen from "Palisade" to "Eastman", an

accuracy of 1:21926 before and 1:30926 after the recent adjustment; "Eastman" to "Teaneck" was

1:11687 and is now 1:20871, while a traverse from "Elizabeth" to "Hale" was 1:15810 and is now1:26394. While the minimum for closure on second order traverse work is 1:10000, most of the

work in South Jersey was far above that l_mit, on an average of about 1:25000.

In some instances the work done by this Survey, espeeially in Union and Mercer Counties did not

fit in the U. S. triangulation within the required limit of 1:10000. The readjustment of the triangu_

latlon of the U. S. Coast and Geodetic Survey in North Jersey eliminates this difficulty now.

METHODS USED IN FIELD AND OFFICE

(A) Trianqulation

All triangulation work of both first and second order was done in accordance with the rigid speci-fications laid down in the manuals of the U. S. Coast and Geodetic Survey, Special Publications Nos.

120 and 145. The northwestern section of the State heretofore had only second order triangulation

which had to be brought up to first order and then broken down into smaller triangles. Other tri-

angulation had to be added to obtain stations along the Delaware River north of Philllpsburg, a section

of the State which had not heretofore been taken in by any triangulation scheme.

In all this work and also in traverse work, a thorough reconnaissance is of utmost importance. In

some instances, existing topographic maps proved to lead to wrong conclusions when intervisibillty of

proposed stations was tested. Wherever it was possible, ground stations were selected to avoid costly

transport of steel towers or the erection of wooden towers made by the triangulation crew.

As soon as the reconnaissance is completed and the monument set, a detailed description of the

location of the new station is made giving the ties and directions to other stations and prominent ob-

jects visible trom the new station. A station is only of value if its description is so clear that it can be

recovered without any difficulty. The descriptions of all existing stations used in any triangulation

scheme were checked and a report made of its recovery giving all details.

In the beginning of triangulation work in the latter part of 1935, observations were attempted in

daylight hut during the past year most of the observation work was done at night time. For thiswork the 1" Parkhurst theodolite and the 5" and 10" theodolites were used. in most cases the direc-

tion method was used, 16 positions taken for first order work and 8 for second order work. A sam-

pie of a field book page for direction observations will be found attached hereto. (See Schedule II).

If the repetition method is used, four sets of six direct and six reverse angles are required for an

instrument with a 10" vernier although there can be no rule set for the number of sets required for

first order work because of the variation in quality of the different types of repeating theodolites. This

method, however, is the better one from the viewpoint of the computer because no local adjustment

is necessary. The error in horizon closure is simply distributed uniformily among the angles meas-ured.

10


(B) Baae Lines

A base tlne, Ellzabeth-Port Reading, was measured with three 50 meter invar tapes which were

held with a tension of 15 ks. Another base llne along the Belleville Turnpike in Hudson Comity wasmeasured with 100 font iovar tapes over 4" x4" stake supports at both ends and center. In both casesthermometers were read at both ends of the tapes and levels taken to obtain the difference in elevationof supports.

(C') Traverses

Reconnaissance and the proper description of all points agalo is of utmost importance. A traverse

point or a monument is only of service to anyone if it can be easily recovered. The location des-

cription, therefore, should be clear, accurate and contain sufficient ties to permanent objects. Thiswas not always possible, especially in sparsely settled rural districts.

All angles on traverse work were measured by the repetition method. Sufl'_clent accuracy is ob-tained with various types of instruments by measuring angles as follows:

Instrument Plate Horizon Limit betweenGraduation Closure Closure 2 sets Repetitions

10" 30 I' for 12 T 5" 4" 2420" 40" for 12 T 7" 5" 36

30" or 1'-0" 1'-0" for 24 T 10" 8" 48

When observing 24 turns 0"-00'-00" was used for the first set and 90"-15'-05" for the second set.

When observing 36 turns, the initial setting for each set was 0"-00'-00"; 60"-05'-10" and 120"10'20".

A set always consisted of measuring the angle six times with the telescope direct and six times withthe telescope reversed.

Schedule III gives sample of a field book page recording a traverse angle measured with an in-

strument having a 1'-0" graduation and Schedule IV shows the record of an angle measured with

a 20" graduation instrument. The sketches appearing on the field book pages illustrate the orderin which the different sets are observed.

Distances between traverse points should he long enough to permit proper sights for angle work.As a general rule, no distance is to be less than 1000 nor more than 2500 feet. In mountainous

country in the northern part of the State or in heavily built up urban areas, it is often not possible

to get sights at least one thousand feet long. In any such case, the traverse had to be lald out so that

an angle control was possible between points more than one thousand feet apart. A traverse loop

between these points was then run in which the distance could be less than one thousand feet and the

angles would be measured only half the number of times, i.e. 24 times on loop points for a 30" and

1'-0" instrument. Quite often the angle control in built up areas was dope over high buildings fromwhich both ends of such loop could be seen.

All angles were computed in the field and turned into the office after completion of each traverse.

(D) Chatnincj

Chaining was done with I00 foot steel tapes over wooden three-legged stools about 24" high.Each distance was chained foreward and backward with the stools at end supports for the tapes which

were kept at tension with a 22 lb. pull registered by a spring balance at the 100 foot end. Ther-

mometers were attached to both ends of the tape and read simultaneously for each tape length.

Levels were taken to determine the incfinat_on of each tape length.

A sample of field notes for chaining is given in Schedule V.

Generally chaining notes were reduced in the field applying temperature and ca,chary correc-

tions and the reduction from the inclined tape length to the horizontal.

II


Upon completion of all angles and all chaining, a strip map of the traverse was prepared showing

angles and distances for all parts of the traverse and giving field book and page number where angles,distances and ties for each traverse point can be found. This facilitated o_ce computation work

considerably.

(E) Leveling'

While angle work was being done, part of the field party, not needed for this work, went aloogthe traverse and set monel rivets for benchmarks at points where permanency of the mark was as-sured. Levels were then run over all monuments and benchmarks along the traverse.

When a Fischer precise level (U. S. Coast and Geodetic Survey owned) was used, the rnnwould be made in one direction only and three readings by stadia hairs in meters were taken on the

front of the rod and one cheek reading was taken in feet on the back of the rod, Sights in thiscase were not more than 300 feet both ways. Where Wye levels were used a forward run would bemade in the forenoon and a backward run over the same points in the afternoon. Sights in this case

were never over 150 feet both ways. All foreward and backward sights for one set up were made

equal in all cases. The permissible dosing error betnveco a forward and, a backward run could notexceed three poe-hundredths of a foot times the square root of the mileage run (0.03 x q Mi).

A sample of level notes is given in Schedule VI.

(F) Magnetic Obaervafions

Schedule VII gives a list of points upon which magnetic observations were made in order to

determine the magnetic declination in various parts of the State. Since these observations were madeat different times over a period of three years, the results have been adjusted to give the declinationfor all stations listed for the year 1935.

{G) Computed.on Work

All field computations sent into the o_ce were checked. The computations for all. triangula-

tion work were made in accordance with the U. S. Coast and Geodetic Survey Manual and on formsprovided therein.

The computations required for tbe establishing Of newtriangulation stations are quite involvedand it would be beyond the purpose of this report to give examples of work done. Each set of

such computations must contain a record of recovery of old triangulation stations, a detailed locationdescription of the new stations, an abstract of directions of all stations occupied, a list of directions,

computations of reduction to center where eccentric observations were made, a set-up of eqnatlbns

used in the least square adjustment for each scheme, position computations giving the geographicpositions of new stations after all triangles in the scheme" have been solved, inverse position computa 5

tlon, a transformation of geographic positions to plane coordinates on the Transverse Mercator Pro-jection and finally a list of geographic positions and of plane _:oordlnates for all new stations.

All field computations for traverse work are likewise checked in the office. The records re-quired for traverse computations comprise an index (ile card, recovery notes for triangulation sta-tions which the traverse connects, descriptions of all monuments along the traverse, a description oi¢

the traverse giving length, number of angles, angle corrections and length correctlon, the closureon final fixed point, the method, of adjustment and the lengths for the various tapes used onthe traverse. A sample of such traverse computations, Cumberland-8 and the records required are

given in Schedule VIII-A through VIII-J. Io this sample there is shown a chaining computationof one distance, a llst of preliminary grid azimuths, the computation of plane coordinates for all points

and a sample of a cmnputatlon of azimuth and distance between pairs of monuments. With eachtraverse goes a copy of the Atlas Secfioo Sheet--in the case at hand, Sectloo 35-5--whlch will be

found among the maps hereto attached.

All level reductions are likewise checked in the bffice. The various runs are then grouped togetherand exequated within the net and the connecting points on U. S. first order runs.

I2


Along with this computation work, all maps are kept up to-date. When a traverse is completedin the field, it is given a designation consisting of the first three ]nltials of the County in whl/:h it

originates and a number conforming to the numerical order in which the traverses are completed;to wit: CUM-8, RER-1, BER-10.

Besides the computations mentioned above, plane coordinates were computed for the intersection

of each minute of longitude with each minute of latitude. These computations are about 65% com-

pleted for the whole State. They serve to facilitate plotting of plane coordinates on U. S. or N. J,Geological Atlas Sheets.

U. S. COAST AND GEODETIC SURVEY CONTROL

Copies of all completed work are flied with tile U, S. Coast and Geodetic Survey in Washingtonwhere computations and descriptions are checked. The original of all computation work and all field

notes are retained in the Newark o_ce and will eventually be turned over to the spottsor, the State

Department of Conservation and Development for maintaining results and extending the Survey asmay be required from time to time. Chapter 225 of P. L. of 1938 provides that this be done,Hmvever, there is no appropriation available at pre_ent with which to do this, The accuracy of all

work must meet the specifications set up by the Coast and Geodetic Survey.

RECORDS ON FILE IN NEWARK

There are now in file in the Newark office, the following records:

1. 1255 Field books of all triangulatlon, traverse and level work.

2. Complete triangulation computations for 14 new stations giving plane coordinate positions,

3. Complete traverse computations for 221 traverses covering 1,858 miles of traverse.

CONNECTING SURVEYS WITH PLANE COORDINATE SYSTEM

For the benefit of engineers employed in public or private work, two samples of connections are

given herewith. The first one is a traverse used in the preparation o_ part of the Tax AssessmentMap in the Borough of Chatham, Morris County. It is shown on Schedule IX-A through IX-G.

13


It begins with a loop formed by the monument line 2351 to 2350 to Pt. 6 to Pc. 12. It wilt be

noted, however, that the short distance in the loop between monument 2350 and Pt. 6 and Pt. 12 arecontrolled by the angle formed by the monument llne 2350 to 235l and the sight from monument 2351to Pc. 12 over which the azimuth is carried further to Pt. 13. The town traverse takes in a num-

ber of blocks north of the N, J. Geodetic Control Survey traverse and ends in the llne between monu-ment 727 and 728.

A sample of t_eld notes for chaining and angles and the rest of the computations are given.

Angles were in this case measured 6 times direct and 6 times reversed with a 10" graduation instru-ment, which was considered of sut_clent accuracy.

The other example is a property survey in Harrington Park, Bergen County, shown on Schedule

X-A through X-E. In this case only a computation of azimuths and of plane coordinates is given.A deed description is also attached giving coordinates for each corner and metes and bounds.

It should be noted that in the first case, the town traverse starts from one fixed monument llne

and runs into another fixed monument line. In the second case, the property llne traverse starts atone point in the monument line and ends _n another point in the same llne. This practice is con-

sidered more safe than, as sometimes is done, running from one monument or one particular point on

a monument llne back to the same point. For facilitating precise chaining computatlon% there arehereto attached Schedule XI giving temperature corrections and Schedule XII-A, XII-B and XII-C

giving grade correc6ons for a 100 foot tape length. There is further attached, as Schedule XIII, aBibliography giving the manuals and publications of the U, S. Coast and Geodetic Survey whichwill prove helpful to the engineering profession in triangulation and traverse work.

MAPS ATTACHED

After Schedule XIII, there will be found attached hereto, 67 Atlas Section Sheets showingtraverses so far completed and filed with the U. S. Coast Geodetic Survey. Following these sheets,

there is one Index Map of the State giving the numbers and showing the area covered by the AtlasSection Sheets.

ACKNOWI,EDGMENT,

In conclusion, the writer may be permitted to give praise to the o/_clals in charge of the WorksProgress Administration for their always ready helpful assistance and cooperation, without which this

project could not have been continued to-date. A word of appreciation should also be given to thepersonnel _mployed in this work. Their zeal and loyalty and their readiness at all times to do theirbest, even under trying conditions, deserves commendation.

In the preparation of the foregoing report, the writer was ably assisted by Richard T. Noble,Supervisor in charge of all field work and Joseph A. Mclnnis in charge of computations.
