PREFACE
This book is intended to be used supplementary
to Class Room lectures, Assigned Reading in a
Standard Text and Field Instructions. :
It contains sample field notes to fundamental
problems or exercises, so arranged as to give correct.
form of notes, and concise information for the solu-
tion of the problems. Blank pages immediately fol-
low each problem for the record of the solution of a
similar problem by the student.
This manual is a product of the teaching staff of
the Department of Engineering.

INTRODUCTION
The theory of Plane Surveying is surprisingly
simple to the well prepared, but the successful appli-
cation of this knowledge comes only from long and
continued experience and the development of good
judgment. Inacollege course it is impracticable to
spend this necessary time, therefore, the aim is to
familiarize the student with the use, care, and adjust-
ment of instruments, the solution of the problems
involving their use, and the methods of recording the
acquired data in a clear and concise manner.
GENERAL INSTRUCTIONS
It is an observed fact that students are usually
very careless in the care of instruments and ap-
paratus. An instrument should be treated kindly,
for their parts are of soft metal, and it is very easy
to strain the instrument by forcing the adjusting
screws. The heads of the thumb screws on the in-
struments give a leverage out of proportion to the
strength of the screw thread, thus they are quite
easy to strip. All movable parts are made to a snug
fit, and should work easily.
If the adjustments are either tight or loose, the
instrument needs attention, and the instructor in
charge should be notified. Further cautions are
given in the texts and class-room.
At Valparaiso University. the instruments are
kept in numbered lockers. A list of the contents of
each locker is found ona card on the inside of the
4
door. To obtain the use of any apparatus the appli-
cant must sign a requisition slip for the key to the
locker. The applicant then becomes responsible for
all apparatus in the locker until the key is returned
and locker checked. After use, every piece of ap-
paratus must be returned in good condition to it’s
place. A penalty is attached to any neglect in this
particular.
As related in the preface, the instruction in this
book is given in form of actual field notes. It is not
intended that the student should follow them literally.
They are given only as a guide to good practice. In
the higher branches of surveying the forms are not
given, they must be made up by the student. He
will by that time be familiar with correct forms, and
can easily plan his notes to suit the particular prob-
lem in hand.
Field notes should be made in their final form in
the field. The practice of putting them on small bits
of paper and transferring them in the office or room
leads to many errors and lost data.
The student whose note book shows lack of skill
in the beginning need not be discouraged as this is
only natural. It is the improvement which counts,
and the notes should show it.
Accuracy should be the chief aim of all survey-
ors. When the results do not come within the per-
missible error, many beginners are tempted to fudge
their notes. Fudging is an indication of laziness and
dishonesty, and is easily detected. It is better to re-
peat the survey several times and fail, than to
sacrifice honesty,—the greatest virtue of the Engi-
neer.
