PREFACE
The Elements of Surveying-, published by the author in
1830, was designed especially as a text-book for the Military
Academy, and in its preparation little regard was had to the
supposed wants of other Institutions.
It was not the aim of the author to make it so elementary
as to admit of its introduction into academies and schools, and
he did not, therefore, anticipate for it an extensive circulation.
It has been received, however, with more favor than was
anticipated, and this circumstance has induced the author to
re-write the entire work. In doing so, he has endeavored to
make it both plain and practical.
It has been the intention to begin with the very elements
of the subject, and to combine those elements in the simplest
manner, so as to render the higher branches of plane-survey-
ing comparatively easy.
All the instruments needed for plotting have been carefully
described ; and the uses of those required for the measurement
of angles are fully explained.
The conventional signs adopted by the Topographical Beau-
reau, and which are now used by the United States Engineers
in all their charts and maps, are given in plates 5 and 6.
Should these signs be generally adopted in the country, it
would give entire uniformity to all maps and delineations of
ground, and would establish a kind of language by which
all the peculiarities of soil and surface could be accurately
represented.
An account is also given of the manner of surveying the
public lands; and although the method is simple, it has,
nevertheless, been productive of great results, by defining,
with mathematical precision, the boundaries of lands in the
new States, and thus settling their titles on an indisputable
basis.

4 PREFACE.
The method was originated by Col. Jared Mansfield, whose
great acquirements in science introduced him to the notice
of President Jefferson, by whom he was appointed surveyor-
general of the North-Western Territory.
May it be permitted to one of his pupils, and a graduate of
the Military Academy, further to add, that at the organization
of the institution in 1812, he was appointed Professor of Nat-
ural and Experimental Philosophy. This situation he filled
for sixteen years, when he withdrew from the academy to
spend the evening of his life in retirement and study. His
pupils, who had listened to his instructions with delight, who
honored his learning and wisdom, and had been brought near
to him by his kind and simple manners, have placed his por-
trait in the public library, that the institution might possess
an enduring memorial of one of its brightest ornaments and
distinguished benefactors.
At the solicitation of several distinguished teachers here is
added, in the present edition, an article on Plane Sailing, most
of which has been taken, by permission of the author, from an
excellent work on Trigonometry and its applications by Pro-
^*~^or Charles Hackley.

INTRODUCTION.
CHAPTER I.
Of Logarithms.
1. The nature and properties of the logarithms in common
use, will be readily vuiderstood, by considering attentively the
different powers of the nmiiber lo. They are,
10'' = i
10' = 10
10* = 100
10^=1000
10^ = 10000
10^ = 100000
&c. &c.
It is plain, that the indices or exponents 0, l, 2, 3, 4, 5, &c.
form an arithmetical series of which the common difference is
1 ; and that the numbers 1, 10, 100, 1000, 10000, 1 00000, &c.
form a geometrical series of which the common ratio is 10,
The number 1 0, is called the base of the system of logarithms ;
and the indices, 0, 1, 2, 3, 4, 5, &c., are the logarithms of the
numbers which are produced by raising 10 to the powers de-
noted by those indices.
2. Let a denote the base of the system of logarithms, m any
exponent, and M the corresponding number : we shall then
have, a'^=M
in which m is the logarithm of M.
If we take a second exponent n, and let JST denote the cor-
responding number, we shall have,
in which n is the logarithm of JV.
If now, we multiply .the first of these equations by the
second, member by member, we have
8 INTRODUCTION.
but since a is the base of the system, m+n is the log-arithm
Mx»N*; hence,
The sum of the loganthms of any two numbers is equal to the
logarithm of their product.
Therefore, the addition of logarithms corresponds to the mul-
tiplication of their numbers,
3. If we divide the equations by each other, member by
member, we have,
but since a is the base of the system, m—n is the logarithm
of — hence :
jsr
If one number be divided by another, the logarithm of the quo-
dent will be equal to the logarithm of the dividend diminished by
that of the divisor.
Therefore, the subtraction of logarithms corresponds to the di-
vision of their numbers.
4. Let us examine further the equations
10^ = 10
10« = 100
io'=iooo
&c. &c.
It is plain that the logarithm of 1 is 0, and that the loga-
rithms of all the numbers between 1 and 10, are greater than
0 and less than 1. They are generally expressed by decimal
fractions : thus,
log 2=0.301030.
The logarithms of all numbers greater than 10 and less
than 100, are greater than 1 and less than 2, and are gen-
erally expressed by 1 and a decimal fraction : thus,
log 50 = 1.698970.
The logarithms of numbers greater than 100 and less than
1000, are greater than 2 and less than 3, and are generally
expressed by uniting 2 Avith a decimal fraction ; thus,
log 126=2.100371.
The part of the logarithm which stands on the left of the
decimal point, is called the cluiracterislic of the logarithm.
OF LOGARITHMS. 9
The characteristic is always one less than the places of integer
figures in the number whose logarithm is taken.
Thus, ill the first case, for numbers between i and 10,
there is but one place of figures, and the characteristic is 0.
For numbers between 10 and 100, there are two places of
figures, and the characteristic is 1 ; and similarly for other
numbers.
TABLE OF LOGARITHMS.
5. A table of logarithms, is a table in which are written
the logarithms of all numbers between 1 and some other given
number. The logarithms of all numbers between l and
10,000 are written in the annexed table.
6. The first column on the left of each page of the table,
IS the column of numbers, and is designated by the letter JV;
the logarithms of these numbers are placed directly opposite
them, and on the same horizontal line.
To find, from the table, the logarithm of any number.
7. If the number is less than 100, look on the first page of
the table, along the column of numbers under JV, until the
number is found : the number directly opposite, in the column
designated log, is the logarithm sought. Thus,
log 9=0.954243.
When the number is greater than 100, and less than 10,000.
8. Since the characteristic of every logarithm is less by
unity than the places of integer figures in its corresponding
number (Art. 4), its value is known by a simple inspection
of the number whose logarithm is sought. Hence, it has not
been deemed necessary to write the characteristics in the table.
To obtain the decimal part of the logarithm, find, in the
column of numbers, the first three figures of the given number.
Then, pass across the page, along a horizontal line, into the
columns marked 0, 1, 2, 3, 4, 5, &c., until you come to the
column which is designated by the fourth figure of the given
number: at this place there are four figures of the required
logarithm. To the four figures so found, two figures taken
from the column marked 0, are to be prefixed. If the four
figures thus found, stand opposite to a row of six figures in the
column marked 0, the two figures from this column, which
are to be prefixed, are the first two on the left hand : but if
10 INTRODUCTION.
the four figures found are opposite a line of only four figures,
you are then to ascend the column till you come to tlie line
of six figures ; the two figures, at the left hand, are to be
prefixed, and then the decimal part of the logarithm is ob-
tained ; to which prefix the characteristic, and you have the
entire logarithm sought. For example,
log 1122 = 3.049993
log 8979===3. 953228
In several of the columns, designated 0, 1,2, 3, 4, &c., small
dots are found. When the logarithm falls at such places,
a cipher must be written for each of the dots, and the two
figures, from the column 0, which are to be prefixed, are then
found in the horizontal line directly below.
Thus, .... 'log 2188 = 3.340047
the two dots being changed into two ciphers, and the 34 to
be taken from the column 0, is found in the horizontal line
directly below.
The two figures from the column 0, must also be taken from
the horizontal line below, if any dots shall have been passed
over, in passing along the horizontal line : thus,
log 3098 = 3.491081
the 49 from the column 0, being taken from the line 310.
When the number exceeds 10,000, or is expressed by Jive or
more figures.
9. Consider all the figures, after the fourth from the left
hand, as ciphers. Find from the table the logarithm of the
first four figures, and to it prefix a characteristic less by unity
than all the places of figures in the given number. Take
from the last column on the right of the page, marked D, the
number on the same horizontal line with the logarithm, and
multiply this number by the figures that have been considered
as ciphers : then cut oflf from the right hand as many places
for decimals as there are figures in the multiplier, and add the
product so obtained to the first logarithm, and the sum will be
the logarithm sought.
Let it be required, for example, to find the logarithm of
672887.
log 672800 = 5.827886
the characteristic being 5, since there are six places of figures.
The corresponding number, in the column J9 is 65, which
OF LOGARITHMS. Jl
being multiplied by 87, the figures regarded as ciphers, gives
for a product 5655 ; then pointing off two decimal places, we
obtain 56.55 for the number to be added.
Hence . . log 672800 = 5.827880
Adding .... +56.55
gives . log 672887=5.827943.
In adding the proportional number, we omit the decimal
part ; but when the decimal part exceeds 5 tenths, as in the
case above, its value is nearer unity than 0 ; in which case,
we augment by one, the figure on the left of the decimal
point.
10. This method of findmg the logarithms of numbers
which exceed four places of figures, does not give the exact
logarithm ; for, it supposes that the logarithms are propor-
tional to their corresponding numbers, which is not rigorously
true.
To explain the reason of the above method, let us take the
logarithm of 672900, a number greater than 672800 by 100.
We then have,
log 672900 = 5.827951
log 672800 = 5.827886
Difference of numbers 100 6 5 =difrerence of loga-
rithms.
Then, 100 : 65 :: 87 : 56.55
In this proportion the first term 100 is the difference be-
tween two numbers, one of which is greater and the other
less than the given number; and the second term 65 is the
difference of their logarithms, or tabular difference.
The third term 87 is the difference betAveen the given num-
ber and the less number 672800; and hence the fourth term
56.55 is the difference of their logarithms. This difference
therefore, added to the logarithm of the less nimiber, will give
that of the greater, nearly.
Had there been three figures of the given number treated
as ciphers, the first term would have been 1000 ; had there
been four, it would have been 10000, &c. Therefore, the
reason of the rule, for the use of the column of differences, is
manifest.
To find the logarithm of a decimal number.
11. If the given number is composed of a Avhole number
GMT U^^^'"-^
12 iNtnODUCTIOW.
and a decimal, such as 36.78, it may be put under the form
»_e_7_8. But since a fraction is equal to the quotient obtained
by dividing the numerator by the denominator, its logarithm
will be equal to the logarithm of the numerator minus the
logarithm of the denominator. Therefore,
log 3_6_7_«3=log 3678 — log 100 = 3.565612 — 2 = 1.565612
from which we see, that a mixed number may be treated
as though it were entire, except in fixing the value of the
characteristic, which is always one less than the number of the
integer figures.
12. The logarithm of a decimal fraction is also readily
found. For,
log 0.8=log j\=\og 8 — l = -l+log 8. But,
log 8=0.903090
which is positive and less than 1. Therefore,
log 0.8 = -l+0. 903090 = — 1.903090
in which, however, the minus sign belongs only to the charade^
ristic. Hence it appears, that the logarithm of tenths is the
same as the logarithm of the corresponding whole number,
excepting, that the characteristic instead of being 0, is— 1.
If the fraction were of the form 0.06 it might be written yVo J
taking the logarithms, we have,
log -0/-=log 06— 2 = -2+log 06 = — 2.778151
in which the minus sign, as before, belongs only to the char-
acteristic. If the decimal were 0.006 its logarithm would be
the same as before, excepting the characteristic, which would
be — 3. It is, indeed, evident, that the negative characteristic
will always be one greater than the number of ciphers be-
tween the decimal point and the first significant figure.
Therefore, the logarithm of a decimal fraction is found, by
considering it as a whole number, and then prefixing to the deci-
mal part of its logarithm a negative characteristic greater by
unity than the number of ciphers between the decimal point ana
Ihe first significant figure.
That we may not, for a moment, suppose the negative sign
to belong to the whole logarithm, when in fact it belongs only
to the characteristic, we place the sign above the characte-
ristic, thus,
log 0 8=1.903090, and log 0.00=2.778151.

To find in the table, the number answering to a given logarithm.
13. Search in the columns of logarithms for the decimal
part of the given logarithm, and if it can be exactly found,
set down the corresponding number. Then, if the character-
istic of the given logarithm is positive, point off from the left
of the number found, one more place for whole numbers than
there are units in the characteristic of the given logarithm,
and treat the figures to the right as decimals.
If the characteristic of the given logarithm is 0, there will
be one place of whole numbers ; if it is — 1, the number will
be entirely decimal; if it is— 2, there will be one cipher
between the decimal point and the first significant figure ;
if it is — 3, there will be two, &c
The number whose logarithm is 1.492481, is found at page
5, and is 31.08.
But when the decimal part of the logarithm cannot be
exactly found in the table, take the number answering to the
nearest less logarithm; take also from the table the corres-
ponding difference in the column D, Then, subtract this
less logarithm from the given logarithm, and having annexed
any number of ciphers to the remainder, divide it by the dif-
ference taken from the column 2?, and annex the quotient to
the number answering to the less logarithm : this gives the
required number, nearly. This rule, like that for finding
the logarithm of a number when the places of figures ex-
ceed four, supposes the numbers to be proportional to their
corresponding logarithms.
1. Find the number answering to the logarithm 1.532708.
Given logarithm is . . 1.532708

Tabular difference . 253)64.00(25
Hence the number sought, is 1712.25, marking four places
for integers since the characteristic is 3.
MULTIPLICATION BY LOGARITHMS.
14. When it is required to multiply numbers by means of
their logarithms, we first find from the table the logarithms
of the numbers to be multiplied ; we next add these loga-
rithms together, and their sum is the logarithm of the pro-
duct of the numbers (Art. 2).
The term sum is to be understood in its algebraic sense ;
therefore, if any of the logarithms have negative charac-
teristics, the difference between their sum and that of the
positive characteristics, is to be taken, and the sign of the
greater prefixed.
EXAMPLES.
1. Multiply 23.14 by 5.062.
log 23.14 = 1.364363
log 5.062=0.704322.
Product 117.1347 . . . . 2.068685
2. Multiply 3.902, 597.16 and 0.0314728 together.
log 3.902 = 0.591287
log 597.16=2.776091
log 0.0314728 = 2.497936
Product 73.3354 .... 1.865314
Here the 2 cancels the + 2, and the 1 carried from the
decimal part is set down.

3. Multiply 3.586, S.1046, 0.8372, and 0.029 4, together.
log 3.586=0.554610

log 0.8372 = 1.922829
log 0.0294 = 2.468347
Product 0.1857615 . . 1.268956.
In this example the 2, carried from the decimal part, can-
cels 2, and there remains T to be set down.
DIVISION OF NUMBERS BY LOGARITHMS.
15. When it is required to divide numbers by means of
their logarithms, we have only to recollect, that the subtrac-
tion of logarithms corresponds to the division of their num-
bers (Art. 3). Hence, if we find the logarithm of the divi-
dend, and from it subtract the logarithm of the divisor, the
remainder will be the logarithm of the quotient.
This additional caution may be added. The difference of
the logarithms, as here used, means the algebraic difference ;
so that, if the logarithm of the divisor have a negative
characteristic its sign must be changed to positive, after
diminishing it by the unit, if any, carried in the subtraction
from the decimal part of the logarithm. Or, if the charac-
teristic of the logarithm of the dividend is negative, it must
be treated as a negative number.
EXAMPLES.
1. To divide 24163 by 4567.

Here, 1 carried from the decimal part to the 3 changes it to
2, which being taken from §, leaves 0 for the characteristic.

4. To divide 0.7438 by 12.9476

log 12.9476 = 1.112189
Quotient 0.057447 . . 2.759267
Here, the l taken from f, gives 2 for a result, as set down.
ARITHMETICAL COMPLEMENT.
16. The Arithmetical complement of a logarithm is the num-
ber which remains after subtracting this logarithm from 10.
Thus . . 10—9.274687 = 0.725313.
Hence, 0.725313 is the arithmetical complement
of 9.274687.
17 We will now show that, the difference between two logo-
rithms is truly found, by adding to the first logarithm tfie arith-
metkal complement of the logarithm to be subtracted^ and then
diminishing the sum by 10.
Let a=the first logarithm
b=the logarithm to be subtracted
and c = io — 6=the arithmetical complement of b,
P^ow the difference between the two logarithms will be
expressed by a—b.
But, from the equation c = lO — b, we have
c~10 = — 6
hence, if we place for— 6 its value, we shall have
a— b=a-\-c— 10
which agrees with the enunciation.
When we wish the arithmetical complement of a logarithm,
we may write it directly from the table, by subtracting the left
hand figure from 9, then proceeding to the rights subtract each
figure from 9 till we reach the last significant figure, which must
be taken from 10 : this will be the same as taking the logarithm
from 10.

Definitions.
1. Geometry is the science which has for its object the
measurement of extension.
Extension has three dimensions, length, breadth, height,
or thickness.
2. A line is length without breadth, or thickness.
The extremities of a line are called points : a point, there-
fore, has neither length, breadth, nor thickness, but position
oiily.

INTRODUCTION.
3. A straight line is the shortest distance from one point to
another.
4. Every line which is not straight, or composed of straight
lines, is a curved line.
Thus, AB is a straight line ; ACDB is
a broken line, or one composed of straight A.
lines ; and AEB is a curved line.
The Avord line, when used alone, will designate a straight
line ; and the word curve, a curved line.
5. A surface is that which has length and breadth, without
height or thickness.
6. A plane is a surface, in which, if two points be assumed
at pleasure, and connected by a straight line, that line will lie
wholly in the surface.
7. Every surface, which is not a plane surface, or composed
of plane surfaces, is a curved surface.
8. A solid or body is that which has length, breadth, and
thickness; and therefore combines the three dimensions of
extension.
9. When two straight hnes, AB,AC,
meet each other, their inclination or open-
ing is called an angle, which is greater or
less as the lines are more or less inclined
or opened. The point of intersection A is
the vertex of the angle, and the lines AB,
AC, are its sides.
The angle is sometimes designed simply by the letter at
the vertex A; sometimes by the three letters BAG, or CAB,
the letter at the vertex being always placed in the middle.
Angles, like all other quantities, are susceptible of addition,
subtraction, multiplication, and division.
Thus tlie angle DCE is the sum
of the two angles DCB, BCE ; and
the angle DCB is the difference of the a
two angles DCE, BCE.

10 When a straight line AB meets
another straight line CD, so as to make
the adjacent angles BAG, BAD, equal to
each other, each of these angles is called a
right angle; and the line AB is said to be
perpendicular to CD.
11. Every angle BAC, less than
a right angle, is an acute angle; and
every angle DEF, greater than a
right angle, is an obtuse angle.
12. Two lines are said to be parallel,
when being situated in the same plane, they
cannot meet, how far soever, either way, —
both of them be produced
13. A plane figure is a plane terminated on
all sides by lines, either straight or curved.
If the lines are straight, the space they en-
close is called a rectilineal figure, or polygon, and
the lines themselves, taken together, form the
contour, or perimeter of the polygon.
14. The polygon of three sides, the simplest of all, is called
a triangle; that of four sides, a quadrilateral ; that of five,
n pentagon ; that of six, a hexagon ; that of seven, a heptagon;
that of eight, an octagon; that of nine a nonagon ; that of
ten, a decagon ; that of twelve, a dodecagon.
15. An equilateral triangle is one which has its three sides
equal ; an isosceles triangle, one which has two of its sides
equal; a scalene triangle, one which has its three sides unequal.
16. A right-angled triangle is one which
has a right angle. The side opposite the
right angle is called the hypothenuse. Thus,
in the triangle ABC, right-angled at A,
the side BC is the hypothenuse.
20 INTRODUCTION.
17. Among the quadrilaterals, we distinguish :
The square, which has its sides equal, and
its angles right angles.
The rectangle, which has its angles right
angles, without having its sides equal.
The parallelogram, or rhomboid, which
has its opposite sides parallel.
The rhombus, or lozenge, which has its sides equal,
o^ithout having its angles right angles.
And lastly, the trapezoid, only two of whose
sides are parallel.
18. A diagonal is a line which joins the
vertices of two angles not adjacent to each
other. Thus, AF, AE, AD, AC, are diagonals.
19. An axiom is a self-evident proposition.
20. A theorem is a truth, which becomes evident by means
of a train of reasoning called a demonstration.
21. A problem is a question proposed, which requires
a solution.
22. A lemma is a subsidiary truth, employed for the de-
monstration of a theorem, or the solution of a problem.
23. The common name, proposition, is applied indifferently,
to theorems, problems, and lemmas.
24. A corollary is an obvious consequence, deduced from
one or several propositions.
25. A scholium is a remark on one or several preceding
propositions, which tends to point out their connexion, their
use, their restriction, or their extension.
26. A hypothesis is a supposition, made either in the eniin-
ciation of a proposition, or in the course of a demonstration.

CHAPTER III.
Description of the Instruments used for Delineating or Drawing
Lines and Angles on paper. Construction of Problems.
18. Drawings, or delineations on paper, are the copies of
things which they are intended to represent.
In order that these copies may be exact, their different parts
must bear the same proportion to each other that exists
between the corresponding parts of the things themselves.
To enable us to delineate lines and angles correctly, upon
paper, certain instruments are necessary ; these we will now
describe.
22
INTRODUCTION.
DIVIDERS.
19. The dividers is the most simple and useful of the in-
struments used for drawing. It consists of two legs 6a, be,
which may be easily turned around a joint at b.
One of the principal uses of this instrument is to lay off on
a line, a distance equal to a given line.
For example, to lay off on CD a dis- ^ ^
tance equal to AB. ' "*
For this purpose, place the forefinger C ^ n
on the joint of the dividers, and set one
foot at A : then extend, with the thumb and other fingers,
the other leg of the dividers, until its foot reaches the point
B. Then raise the dividers, place one foot at C, and mark
with the other the distance CE : this will evidently be
equal to AB.
RULER AND TRIANGLE.
20. A Ruler of a convenient size, is about twenty inches
in length, two inches wide, and a fifth of an inch in thick-
ness. It should be made of a hard material, perfectly straight
and smooth.
The hypothenuse of the right-angled triangle, which is
used in connexion with it, should be about ten inches in
DESCRIPTION OF INSTRUMENTS. 23
length, and it is most convenient to have one of the sides
considerably longer than the other. We can solve, with the
ruler and triangle, the two following problems.
I. To draw through a given point a line which shall be parallel
to a given line.
Let C be the given point, and AB the
given line. 1
Place the hypothenuse of the triangle ^ ^
against the edge of the ruler, and then ""
place the ruler and triangle on the paper, so that one of the
sides of the triangle shall coincide exactly with AB : the
triangle being below the line.
Then placing the thumb and fingers of the left hand firmly
on the ruler, slide the triangle with the other hand along the
ruler until the side which coincided with AB reaches the
point C Leaving the thumb of the left hand an the ruler,
extend the fingers upon the triangle and hold it firmly, and
with the right hand, mark with a pen or pencil, a line through
C: this line will be parallel to AB.
n. To draw through a given point a line which shall be per-
pendicular to a given line.
Let AB be the given line, and D the ip
given point.
Place the hypothenuse of the triangle .
against the edge of the ruler, as before.
Then place the ruler and triangle so that one of the sides of
the triangle shall coincide exactly with the line AB. Then
slide the triangle along the ruler until the other side reaches
the point D: draw through D a right line, and it will be per«
pendicular to AB.
SCALE OF EQUAL PARTS.

21. A scale of equal parts is formed by dividing a line of a
given length into equal portions.
If, for example, the line ab of a given length, say one inch, be
divided into any number of equal parts, as 10, the scale thus
formed, is called a scale of ten parts to the inch. The line
24
rNTRODUCTION.

a6, which is divided, is called the i*m^ o/i/ie scale. This unit
is laid off several times on the left of the divided line, ani
the points marked, 1, 2, 3, &c.
The unit of scales of equal parts, is, in general, either an
mch, or an exact part of an inch. If, for example, ab the
unit of the scale, were half an inch, the scale would be one
of 10 parts to half an inch, or of 20 parts to the inch.
If it were required to take from the scale a line equal to
two inches and six-tenths, place one foot of the dividers at 2
on the left, and extend the other to .6, which marks the sixth
of the small divisions : the dividers will then embrace the
required distance.

22. This scale is thus constructed. Take ah for the unit
of the scale, which may be one inch, i, i or | of an inch,
in length. On ah describe the square ahcd. Divide the sides
ah and dc each into ten equal parts. Draw aj and the other
nine parallels as in the figure.
Produce ha to the left, and lay off the unit of the scale any
convenient number of times, and mark the point 1, 2, 3, &c.
Then, divide the line ad into ten equal parts, and through the
points of division draw parallels to ah as in the figure.
Now, the small divisions of the line ah are each one-tenth
(.1) of ah; they are therefore .1 of ad., or .1 of ««• or gh.
If we consider the triangle adj., the base df is one-tenth
of ad the unit of the scale. Since the distance from a to the
first horizontal line above a6, is one tenth of the distance arf,
11 follows that the distance measured on that Ime between ad
DESCRIPTION OF INSTRUMENTS.
26
And af is one-tenth of dj : but since one-tenth of a tenth is a
hundredth, it follows that this distance is one hundredth (.01)
of the unit of the scale. A like distance measured on the
second line will be two hundredths (.02) of the unit of the
scale ; on the third, .03 ; on the fourth, .04, &c.
If it were required to take, in tlie dividers, the unit of the
scale, and any number of tenths, place one foot of the dividers
at 1, and extend the other to that figure betv/een a and h
which designates the tenths. If two or more units, are re-
quired, the dividers must be placed on a point of division
farther to the left.
When units, tenths, and hundredths, are required, place one
foot of the dividers where the vertical hue through the point
which designates the units, intersects the line which desig-
nates the hundredths : then, extend the dividers to that Hne
between ad and be which designates the tenths : the dis-
tance so determined will be the one required.
For example, to take off the distance 2.34, we place one
foot of the dividers at /, and extend the other to e ; and to
take off the distance 2.58, we place one fool of the dividers
at p and extend the other to q.
Remark I. If a line is so long that the whole of it can-
not be taken from the scale, it must be divided, and the parts
of it taken from the scale in succession.
Remark II. If a line be given upon the paper, its length can
be found by taking it ia the dividers and applying it to the scale.
SCALE OF CHORDS,
D^?

23. If, with any radius, as AC, we describe the quadrant
CD, and then divide it into 90 equal parts, each part is called
9 '\egree
26 INTRODUCTION.
Through C, and each point of division, let a chord be
drawn, and let the lengths of these chords be accurately laid
off on a scale : 3uch a scale is called a scale of chords. In
the figure, the chords are drawn for every ten degrees.
The scale of chords being once constructed, the radius of
the circle from which the chords were obtained, is known ;
for, the chord marked 60 is always equal to the radius of the
circle. A scale of chords is generally laid down on the scales
which belong to cases of mathematical instruinents, and is
marked ciio.
To lay off, at a given point of a line, with the scale of chords,
an angle equal to a given angle.
Let AB be the line, and Jl the given
point.
Take from the scale the chord of 6 0 de- ^^
grees, and with this radius and the point ^^^2_^ \
.^ as a centre, describe the arc BC. Then -^ ^
take from the scale the chord of the given angle, say 30
degrees, and with this line as a radius, and 5 as a centre,
describe an arc cutting BC in C. Through Jl and C draw
the line AC, and BAC will be the required angle.
Cx-
SEMICIRCULAR PROTRACTOR.
24. This instrument is used to lay down, or protract angles.
It may also be used to measure angles included between lines
already drawn upon paper.
DESCRIPTION OF INSTRUMENTS.
27
It consists of a brass semicircle ABC divided to half de-
grees. The degrees are numbered from 0 to 180, both ways ;
that is, from A to B and from B to A. The divisions, in the
figure, are only made to degrees. There is a small notch at
the middle of the diameter AB, which indicates the centre of
the protractor.
To lay off an angle with a Protractor.
Place the diameter AB on the line, so that the centre shall
fall on the angular point. Then count the degrees contained
in the given angle from A towards B, or from B towards A
and mark the extremity of the arc with a pin. Remove the
protractor, and draw a line through the point so marked and
the angular point : this line will make with the given line the
required angle.
SECTORAL SCALE OP EQUAL PARTS.
25. The sector is an instrument generally made of ivory or
brass. It consists of two arms, or sides, which open by turn-
ing round a joint at their common extremity.
There are several scales laid down on the sector : those,
however, which are chiefly used in drawing lines and angles,
are, the scale of chords already described, and the scale of
equal parts now to be explained.
On each arm of the sector, there is a diagonal line that
passes through the point about which the arms turn: these
diagonal lines are divided into equal parts.
On the sectors which belong to the cases of English in-
struments, the diagonal lines are designated by the letter Z»,
and numbered from the centre of the sector, 1, 2, 3, 4, 5, 6, 7,
8, 9, 10, to the two extremities. On the sectors which belong
28 INTRODUCTION.
to cases of French instruments, they are desi^ated, " Les
parties egales," and numbered, 10, 20, 30, 40, &c. to 200.
On the English sectors there are 20 equal divisions between
either two of the hues nurnbered 1, 2, 3, &c., so that, there are
200 equal parts on the scale.
The advantage of the sectoral scale of equal parts, is this —
When it is proposed to draw a line upon paper, on such a
scale that any number of parts of the line, 40 for example,
shall be represented by one inch on the paper, or by any part
of an inch, take the inch, or part of the inch from the scale
of inches on the sector: then, placing one foot of the dividers
at 40 on one arm of the sector, open the sector until the other
foot reaches to the corresponding number on the other arm :
then lay the sector on the table without varying the angle.
Now, if we regard the lines on the sector as the sides of a
triangle, of which the line 40 measured across, is the base, it
is plain, that if any other line be likewise measured across the
angle of the sector, the bases of the triangles, so formed, will
be proportional to their sides. Therefore, if we extend the
dividers from 50 to 50, this distance will represent a line of 50,
to tbe given scale : and similarly for other lines.
Let it now be required to lay down a line of sixty-seven feet,
to a scale of twenty feet to the inch.
Take one inch from the scale of inches : then place one
foot of the dividers at the twentieth division, and open the
sector until the dividers will just reach the twentieth division
on the other arm : the sector is then set to the proper angle ;
after which the required distance to be laid down on the paper,
is found, by extending the dividers from the sixty-seventh
division on one arm, to the sixty-seventh division on the
other.
GUNTERS' SCALE.
26. This is a scale of two feet in length, on the faces of
which a variety of scales are marked. The face on which the
divisions of inches are made, contains, however, all the scales
necessary for laying down lines and angles. These are, the
scale of equal parts, the diagonal scale of equal parts, and the
scale of chords, all of which have been described.

PROBLEM VII.
To lay down, on paper, a line of a given length, so that any
number of its parts shall correspond to the unit of the scale.
33. Suppose that the given line were 75 feet in length, and
it were required to draw it on paper, on a scale of 25 feet to
the inch.
SOLUTION OF PROBLEMS. 31
The length of the hne 75 feet, being divided by 25, will -give
3, the number of inches which will represent the line on
paper
Therefore, draw the indefinite line .S.B, on which lay of! a
distance AC equal to 3 inches: AC will represent the given
line of 75 feet draw^n to the required scale.
Remark I. This problem explains the manner of laying
dow^n a line upon paper, in such a manner that a given num-
ber of parts shall correspond to the unit of the scale, whether
that unit be an inch or any part of an inch.
When the length of the line to be laid down is given, and it
has been determined how many parts of it are to be repre-
sented on the paper by a distance equal to the unit of the
scale, we find the length which is to be taken frv ^vi the scale
by the following
RULE.
Divide the length of the line by the number of parts which is to
be represented by the unit of the scale : the quotient will show the
number of parts which is to be taken from the scale.
EXAMPLES.
1. If a line of 640 feet in length is to be laid down on
paper, on a scale of 40 feet to the inch ; what length must
be taken from the scale ?
40)640(16 inches.
2. If a line of 357 feet is to be laid down on a scale of 6S
feet to the unit of the scale, (which we will suppose half an
inch), how many parts are to be taken?
Ans. \ ^•^^' P^'^f' ^'
I 2.62 5 inches.
Remark II. When the length of a hne is given on the
paper, and it is required to find the true length of the line
which it represents, take the line in the dividers and apply it
to the scale, and note the number of units, and parts of an
32
INTRODUCTION.
unit to which it is equal. Then multiply this number by the
mmiber of parts which the imit of the scale represents, and
the product will be the length of the line.
For example, suppose the length of a line drawn on the
paper was found to be 3. 50 inches, the scale being 40 feet to
the inch : then,
3.56 X 40=142 feet, the length of the line.

the point O where these perpendiculars

The same construction serves for
making a circumference pass through

describing a circumference, about a given triangle.
CHAPTER III.
Plane Trigonometry*
39. In every plane triangle there are six parts : three sides
and three angles. These parts are so related to each other,
that if a certain number of them are known or given, the re-
maining ones can be determined.
40. Plane Trigonometry explains the methods of finding, by
calculation, the unknown parts of a triangle when a sufficient
number of the six parts is given^
It has already been shown, in the problems, that triangles
may be constructed when three parts are known. But these
constructions, which are called graphic methods, though per-
fectly correct in theory, would give only a moderate approxi-
mation in practice, on account of the imperfection of the in
struments required in constructing them.
Trigonometrical methods, on the contrary, being inde-

41. For the purposes of trigonometrical calculations, the cir-
cumference of the circle is divided into 360 equal parts, called
degrees; each degree into 60 equal parts, called minutes;
and each minute into 6 0 equal parts, called seconds.

As the circumference of a circle may be regarded as a pro-
per measure of angles, having their vertices at the centre, the
four right angles which can be formed about the same point,
are measured by 360 degrees ; two right angles by 180 de
grees, one right angle by 90 degrees, and an angle less
than a right angle, by an arc less than 90 degrees.
Degrees, minutes, and seconds, are usually designated by
the respective characters, ° ' ". Thus, 16" 12' 15" is read,
16 degrees, 12 minutes, and 15 seconds.
42. The complement of an arc is -^
what remains after subtracting the
arc from 90°. Thus, the arc EB is
the complement of AB. The sum of
an arc and its complement is equal
to 90°.
43. The supplement of an arc is
what remains after subtracting the
arc from 180°. Thus, Gl^ is the sup- q
plement of the arc AEF. The sum of an arc and its sup-
plement is equal to 180°.
44. The sine of an arc is the perpendicular let fall from one
extremity of the arc on the diameter which passes through
the other extremity. Thus, BD is the sine of the arc t^B.
45. The cosine of an arc is the part of the diameter inter-
cepted between the foot of ths sine and centre. Thus, OD is
the cosine of the arc AB.
46. The tangent of an arc is the line which touches it at
one extremity, and is limited by a line drawn through the
other extremity and the centre of the circle. Thus, AC is the
tangent of the arc AB.
47. The secant of an arc is the line drawn from the centre
of the circle through one extremity of the arc, and limited by
the tangent passing through the other extremity. Thus, OC
is the secant of the arc AB.
48. The four lines, BD, OD, AC, OC, depend for their
values on the arc AB and the radius OA ; they are thus
designated :

49. If ABE be equal to a quad-
rant, or 90°, then EB Avill be the
complement of AB. Let the lines
ET and IB be drawn perpendicular
to OE. Then,
ET, the tangent of EB, is called the cotangent of AB;
IB, the sine of EB, is equal to the cosine of AB ;
OT, the secant of EB, is called the cosecant of AB,
In general, if A is any arc or angle, we have,
cos A=s\n {900 — A)
cot .^=tan (900 — ^)
cosec*^=sec (900 — ^3)
50. If we take an arc ABEF, greater than 90°, its sine
will be FH ; OH will be its cosine ; ^Q its tangent, and 0(2
its secant. But FH is the sine of the arc GF, which is the
supplement of AF, and OH is its cosine : hence, the sine of
an arc is equal to the sine of its supplement ; and the cosine of
an arc is equal to the cosine of its supplement."^
Furthermore, AQ^ is the tangent of the arc AF, and OQ, is
its secant : GL is the tangent, and OL the secant, of the sup-
plemental arc GF. But since AQ is equal to GL, and OQ, to
OL, it follows that, the tangent of an arc is equal to the tan-
gent of its supplement ; and the secant of an arc is equal to the
secant of its supplement.^
Let us suppose, that in a circle of a given radius, th.e lengths
of the sine, cosine, tangent, and cotangent, have been calcu-
lated for every minute or second of the quadrant, and arranged
in a table ; such a table is called a table of sines and tangents.
If the radius of the circle is 1, the table is called a table of
natural sines. A table of natural sines, therefore, sliows the
+ These relations are between the vdues of the trigonometrical lines; the
algebraic signs, wliich they have in the different quadrants, are not considered.

values of the sines, cosines, tangents and cotangents of all
the arcs of a quadrant, divided to minutes or seconds.
If the sines, cosines, tangents and secants are known for
arcs less than 90°, those for arcs which are greater can be
found from them. For if an arc is less than 90°, its supple-
ment will be greater than 90°, and the values of these lines
are the same for an arc and its supplement. Thus, if we know
the sine of 20°, we also know the sine of its supplement 160°;
for the two are equal to each other.
TABLE OF LOGARITHMIC SINES.
51. In this table are arranged the logarithms of the nu-
merical values of the sines, cosines, tangents and cotan-
gents of all the arcs of a quadrant, calculated to a radius
of 10,000,000,000. The logarithm of this radius is 10. In
the first and last horizontal lines of each page, are written the
degrees whose sines, cosines, &c. are expressed on the page.
The vertical columns on the left and right, are columns of
minutes.
CASE I.
To Jind, in the table, the logarithmic sine, cosine, tangent, or
cotangent of any given arc or angle.
52. If the angle is less than 45°, look for the degrees in the
first horizontal line of the different pages : then descend along
the column of minutes, on the left of the page, till you reach
the number showing the minutes : then pass along the hori-
zontal line till you come into the column designated, sine,
cosine, tangent, or cotangent, as the case may be : the number
so indicated is the logarithm sought. Thus, on page 37, for
19" 55' we find,
sin 19° 55' . . 9.532312
cos 19° 55' . . 9.973215
tan 19° 55' . . 9.559097
cot 19° 55' . . 10.440903
53. If the angle is greater than 45°, search for the degrees
along the bottom line of the different pages : then, ascend
along the column of mmutes on the right hand side of the
page, till you reach the number expressing the minutes : then
pass along the horizontal hne into the columns designated
S8 INTRODUCTION.
tang, cot, sine, or cosine, as the case may be ; the number so
pointed out is the logarithm required.
54. The column designated sine, at the top of the page, is
designated cosine at the bottom ; the one designated tang, by
cotang, and the one designated cotang, by tang.
The angle found by taking the degrees at the top of the
page and the minutes from the first vertical column on the
left, is the complement of the angle found by taking the cor-
responding degrees at the bottom of the page, and the minutes
traced up in the right hand column to the same horizontal
line. Therefore, sine, at the top of the page, should correspond
with cosine, at the bottom ; cosine with sine, tang with cotang,
and cotang with tang, as in the tables (Art. 49).
If the angle is greater than 90°, we have only to subtract it
from 180°, and take the sine, cosine, tangent or cotangent of
the remainder.
The column of the table next to the column of sines, and
on the right of it, is designated by the letter D, This column
is calculated in the following manner.
Opening the table at any page, as 42, the sine of 24° is
found to be 9.609313 ; that of 24° 01', 9.609597: their dif-
ference is 284 ; this being divided by 60, the number of seconds
in a minute, gives 4.73, which is entered in the column Z^,
omitting the decimal point.
Now, supposing the increase of the logarithmic sine to be
proportional to the increase of the arc, and it is nearly so for
60", it follows, that 473 (the last two places being regarded as
decimals), is the increase of the sine for l". Similarly, if the
arc were 24° 20' the increase of the sine for l", would be 465,
the last two places being decimals
The same remarks are equally applicable in respect of the
column D, after tlie column cosine, and of the column D, be-
tween the tangents and cotangents. The column D, between
the columns tangents and cotangents, answers to both of these
columns.
Now, if it were required to find the logarithmic sine of an
arc expressed in degrees, minutes, and seconds, we have only
to find the degrees and minutes as before ; then, multiply the
corresponding tabular number by the seconds, cut off two
places to the right hand for decimals, and then add the pro-
duct to the number first found, for the sine of the given arc.

Thus, if we wish the sine of 40° 26' 28".

Number of seconds .28 . .
Product . . 69 16 to be added 69.16
Gives for the sine of 40« 36' 28" 9.812021.
The decimal figures at the right are generally omitted
in the last result ; but when they exceed five-tenths, the
figure on the left of the decimal point is increased by i ; this
gives the result to the nearest unit.
The tangent of an arc, in which there are seconds, is found
in a manner entirely similar. In regard to the cosine and
cotangent, it must be remembered, that they increase while
the arcs decrease, and decrease as the arcs are increased ; con-
sequently, the proportional numbers found for the seconds,
must be subtracted, not added.

We shall now demonstrate the principal theorems of Plane
Trigonometry.
THEOREM I.
The sides of a plane triangle are 'proportional to Vie sines of
their opposite angles.
67. Let ABC be a triangle ; then will
CB : CA :: sin A : sin B.
For, with .^ as a centre, and AD
equal to the less side BC, as a radius,
describe the arc DI : and with B as
a centre and the equal radius BC, .
describe the arc CL : now DE is the
sine of the angle A, and CF is the sine of B, to the same
radius AD or BC. But by similar triangles,
AD : DE :: AC : CR
El L
PLANE TRIGONOMETRY. 41
But AD being equal to BC, we have
BC : s'mA:: AC : sm B, or
BC : AC ::smA : sin J5.
By comparing the sides AB, AC, in a similar manner, we
should find, AB : AC :: sin C : sin B,
THEOREM II.
In any triangle, the sum of the two sides containing either
angle, is to their difference, as the tangent of half the sum of
the two other angles, to the tangent of half their difference,
58. Let ACB be a triangle : then will
AB-]-AC: AB-AC: : tan i(C+^) : tan i(C-jB).
With ,^ as a centre, and a radius
AC the less of the two given sides, ,\"
let the semicircle IFCE be de- < \
scribed, meeting AB in /, and BA \
produced, in E. Then, BE will \
be the sum of the sides, and Bl ^. pr-rr
their difference. Draw C/ and .^7^.
Since CAE is an outward angle of the triangle ACB, it is
equal to the sum of the inward angles C and B (Bk. I, Prop.
XXV, Cor. 6). But the angle CIE being at the circumfe-
rence, is half the angle CAE at the centre (Bk. Ill, Prop.
XVIII) ; that is, half the sum of the angles C and B, or
equal to i(C+J5).
The angle AFC=ACB, is also equal to ABC+BAF ;
therefore, BAF=ACB-ABC.
But, ICF={{BAF)=\{ACB-ABC), or \{C-B).
With / and C as centres, and the common radius IC, let
the arcs CD and IG be described, and draw the lines CE and
IH perpendicular to IC. The perpendicular CE will pass
through E, the extremity of the diameter IE, since the right
angle ICE must be inscribed in a semicircle.
But CE is the tangent of CIE = \{C+B) ; and IH \s the
tangent of ICB = \{C--B), to the common radius CI.
But since the lines CE and IH are parallel, the triangles
BHI and BCE are similar, and give the proportion,
BE : BI :: CE : IH, or
by placing for BE and BI, CE and IH, their values, we have
AB+AC : AB-AC : : tan i(C+B) • tan 1{C-B).
42 INTRODUCTION.
THEOREM III.
In any plane triangle, if a line he drawn from the vertical
angle perpendicular to the base, dividing it into two segments :
then, the whole base, or sum of the segments, is to the sum of the
other two sides, as the difference of those sides to the difference
of the segments.
59. Let BAC be a triangle, and AD perpendicular to the
base ; then will
BC: CA+AB:: CA-AB : CD-^DB
For, AB'=BD'+AD^
(Bk. IV, Prop. XI) ;
and AC^=DC^+AD^
by subtraction AC^^AB^=CD^—
BD\
But since the difference of the squares ^
of two lines is equal to the rectangle
contained by their sum and difference (Bk. IV, Prop X), we
have,
AC^--AB' = (AC+AB). (AC-AB)
and CD'-DB^ = {CD+DB). (CD-DB)
therefore, {CD+DB).{CD-DB) = (AC+AB).{AC^AB)
hence, CD+DB : AC+AB : : AC-AB : CD-DB.
THEOREM IV.
In any right-angled plane triangle, radius is to the tangent
of either of the acute angles, as the side adjacent to the side
opposite.
60. Let CAB be the proposed triangle,
and denote the radius by R : then will
R. i^nC : AC : AB.
For, with any radius as CD describe
the arc DH, and draw the tangent jDCr. ^ D ^
From the similar triangles CDG and CAB we shall have,
CD : DG:: CA: AB; hence, *
R : tan C : : CA : AB.
By describing an arc with 5 as a centre, we could show in
the same manner that,
R : idiu B :: AB : AC.
PLANE TRIGONOMETRY. 4S
THEOREM V.
In every right-angled plane triangle, radius is to the cosine oj
either of the acute angles, as the hypothenuse to the side adjacent.
61. Let ABC be a triangle, right
angled at B then will
R : cos A : AC : AB.
For, from the point .^ as a centre, and
any radius as AD, describe the arc DF, ^^
which will measure the angle A, and draw jDiJ perpendicular
io AB : then will AE be the cosine of A.
The triangles ADE and ACB, being similar, we have
AD : AE : : AC : AB : thatis,
jR : cos ^ ; : AC: AB.
62. Remark. The relations between the sides and angles
of plane triangles, demonstrated in these five theorems, are suf-
ficient to solve all the cases of Plane Trigonometry. Of the
six parts which make up a plane triangle, at least three must
be given, and one of these a side, before the others can be de-
termined.
If the three angles are given, it is plain, that an indefi-
nite number of similar triangles may be constructed, the
angles of which shall be respectively equal to the angles
that are given, and therefore, the sides could not be de-
termined.
Assuming, with this restriction, any three parts of a triangle
as given, one of the four following cases will always be pre-
sented.
I. When two angles and a side are given.
II. When two sides and an opposite angle are given.
III. When two sides and the included angle are given.
IV. When the three sides are given.
CASE I.
When two angles and a side are given.
63. Add the given angles together and subtract their sum
from 180 degrees. The remaining parts of the triangle can
then be found by Theorem I.

INSTRUMENTALLY.
Draw an indefinite straight line AB, and from the scale of
equal parts lay off AB equal to 408. Then at A lay off an
angle equal to 58° 07', and at B an angle equal to 22" 37', and
draw the lines AC and BC : then will ABC be the triangle
required.
The angle C may be measured either with the protractor or
the scale of chords (Arts. 23 and 24), and will be found equal
to 99° 16'. The sides AC and BC may be measured by re-
ferring them to the scale of equal parts (Art. 22). We shall
find .^0 = 158.9 and BC=S5l yards.

Remark. The logarithm of the fourth term of a proportion
IS obtained by adding the logarithm of the second term to that
of the third, and subtracting from their sum the logarithm of
the first term. But to subtract the first term is the same as
to add its arithmetical complement and reject 1 0 from the sinn
(Art. 17) : hence, the arithmetical complement of the first
term added to the logarithms of the second and third terms,
will give the logarithm of the fourth term.

The ambiguity in this, and similar examples, arises in conse-
quence of the first proportion being true for either of the angles
ABC, or AB'C, which are supplements of each other, and
therefore have the same sine (Art. 43). As long as the two tri-
angles exist, the ambiguity will continue. But if the side CB,
opposite the given angle, is greater than AC, the arc BB' will
cut the line ABB', on the same side of the point A, in but one

point, and then there will be only one triangle answering the
conditions.
If the side CB is equal to the perpendicular Cd, the
arc BB' will be tangent to ABB', and in this case also there will
be but one triangle. When CB is less than the perpendicular
Cd, the arc BB' will not intersect the base ABB', and in that
case, no triangle can be formed, or it will be impossible to fuU
fil the conditions of the problem.
2. Given two sides of a triangle 50 and 40 respectively, and
the angle opposite the latter equal to 32" : required the remain-
ing parts of the triangle.
Ans, If the angle opposite the side 50 is acute, it is equal
to 41028' 59"; the third angle is then equal to 1060 31'01",
and the third side to 72.368. If the angle opposite the side
50 is obtuse, it is equal to 138° 31' 01", the third angle to
9" 28' 59", and the remaining side to 12.436.
CASE III.
When the two sides and their included angle are given.
65. Let ABC be a triangle ; AB, j^
EC, the given sides, and B the given
angle.
Since B is known, we can find the
sum of the two other angles : for
A+C=180'--B and

We next find half the difference of the angles A and C by

in which we consider BC greater than BA, and therefore A
is greater than C ; since the greater angle must be opposite
the greater side.
Having found half the difference of A and C, by adding il
to the half sum \{A-{-C), we obtain the greater angle, and by
subtractmg it from half the sum, we obtain the less. That is

Draw an indefinite right line BC and from any point,

half the base, gives the greater segment; and, being sub-
tracted from half the base, gives the less segment. Then,
since, the greater segment belongs to the right-angled triangle
having the greatest hypothenuse, we have the sides and right
angle of two right-angled triangles, to find the acute an-
gles.

ELEMENTS OF SURVEYING.
CHAPTER 1.
Definitions and Introductory Remarks,
68. Surveying, in its most extensive signification, com-
prises all the operations necessary .for finding,
1st. The area or content of any portion of the surface of
the earth ;
2d. The lengths and directions of the bounding lines;
and
3d. The accurate delineation of the whole on paper.
69. The earth being spherical, its surface is curved, and
every line traced on its surface is also curved.
If large portions of the surface are to be measured, such
as states and territories, the curvature must be taken into
account ; and very material errors will arise if it be neglected.
When the curvature is considered, the method of measure-
ment and computation is called Geodesic Surveying.
The radius of the earth, however, being large, the curva-
ture of its surface is small, and when the measurement is
limited to small portions of the surface, the error becomes
insensible, if we consider the surface a plane. This method
of measurement and computation, is called Plane Surveying,
and is the only kind that will be treated of in these Elements.
70. If at any point of the surface of the earth, a plane be
drawn perpendicular to the radius passing through this point,
such plane is tangent to the surface, and is called a horizontal
plane. All planes parallel to such a plane, are also called
horizontal planes.
71. A plane which is perpendicular to a horizontal plane
is called a vertical plane.
52 ELEMENTS OF SURVEYING.
72. All lines of a horizontal plane, and all lines which are
parallel to it, are called horizontal lines.
73. Lines which are perpendicular to a horizontal plane,
are called vertical lines ; and all lines which are inclined to it,
are called oblique lines.
Thus, *^B and DC are hori- j)^ _^^
zontal lines ; BC and JID are ver-
tical lines ; and AC and BD are
oblique lines.
74. The horizontal distance be- -,,«^^^^^=^^
tween two points, is the horizontal line intercepted between
the two vertical lines passing through those points. Thus,
DC or AB is the horizontal distance between the two points
A and C, or the points B and D.
75. A horizontal angle is one whose sides are horizontal ; its
plane is also horizontal.
A horizontal angle may also be defined to be, the angle
included between two vertical planes passing through the angular
point, and the two objects which subtend the angle.
76. A vertical angle is one, the plane of whose sides is
vertical.
77. An angle of elevation, is a vertical angle having one of
its sides horizontal, and the inclined side above the horizontal
side.
Thus, in the last figure, BAC is the angle of elevation
from A to C
78. An angle of depression, is a vertical angle having one
of its sides horizontal, and the inclined side under the hori-
zontal side. Thus, DCA is the angle of depression from
C to A.
79. An oblique angle is one, the plane of whose sides is
oblique t6 the horizontal plane.
80. All lines, which can be the object of measurement,
must belong to one of the classes above named, viz. :
1st. Horizontal lines :
2d. Vertical lines :
3d. Oblique lines.
All the angles may also be divided into three classes, viz. :
1st. Horizontal angles :
MEASUREMENT OF LINES.
'?d. Vertical angles ; which may be again divided into
angles of elevation and angles of depression : and
3d. Oblique angles.
CHAPTER II.
Of the measurement and calculation of Lanes and Angles.
81. It has been shown (Art. 62), that at least one side and
two of the other parts of a plane triangle must be given or
known, before the remaining parts can be found by calculation.
When, therefore, distances are to be found, by trigonomet-
rical calculations, two things are necessary.
1st. To measure certain lines on the ground; and also, as
many angles as may be necessary to render at least three
parts of every triangle known : and
2d. To calculate, by trigonometry, the other sides and
angles that may be required. Our attention, then, is di-
rected,
1st. To the measurement of lines ;
2d. To the measurement of angles ; and
3d. To the calculations for the unknown and required
parts.
82. Any tape, rod, or chain, on which equal parts are
marked, may be used as a measure ; and one of the equal
parts into which the measure is divided, is called the unit of
the measure. The unit of a measure may be a foot, a yard,
a rod, or any other ascertained distance.
83. The measure in general use, is a chain of four rods or
sixty-six feet in length ; it is called Gunter's chain, from the
name of the inventor. This chain is composed of 100 links.
Every tenth link from either end, is marked by a small
attached brass plate, which is notched, to designate its num-
ber from the end. The division of the chain into lOo equal
parts, is a very convenient one, since the divisions or links,
are decimals of the whole chain, and in the calculations may
be treated as such.
54 ELEMENTS OF SURVEYING.
TABLE.
1 chain = 4 rods = 66 feet = 792 inches= 100 links
Hence, l link is equal to 7.92 inches.
80 chains = 320 rods = l mile.
40 chains = I mile.
20 chains = i mile.
84. Besides the chain, there are wanted for measuring, ten
marking pins, which should be of iron, about ten inches in
length and an eighth of an inch in thickness. These pins
should be strung upon an iron ring, and this ring should be
attached to a belt, to be passed over the right shoulder,
suspending the pins at the left side. Two staves are also
required. They should be about six feet in length, and have
a spike in the lower end to aid in holding them firmly, and a
horizontal strip of iron to prevent the chain from slipping off;
these staves are to be passed through the rings at the ends of
the chain.
TO MEASURE A HORIZONTAL LINE.
85. At the point where the measurement is to be begun,
place in a vertical position, a signal staff, having a small flag
attached to its upper extremity ; and place another at the
point where the measurement is to be terminated. These two
points are generally called stations.
Having passed the staves through the rings of the chain,
let the ten marking pins and one end of the chain be taken by
the person who is to go forward, and who is called the leader,
and let him plant the staff as nearly as possible in the direc-
tion of the stations. Then, taking the staflT in his right hand,
let him stand off at arm's length, so that the person at the
other end of the chain can align it exactly with the stations :
when the alignment is made, let the chain be stretched and a
marking pin placed ; then measvire a second chain in the
same manner, and so on, until all the marking pins shall have
been placed. When the marking pins are exhausted, a note
should be made, that ten chains have been measured ; alter
which, the marking pins are to be returned to the leader, and
the measurement continued as before, until the whole distance
is passed over
OF THE THEODOLITE.
55
Great, care must be taken to keep the chain horizontal, and
if the acclivity or decUvity of the ground be too great to
admit of measuring a whole chain at a time, a part of a
chain only should be measured : the sum of all the horizon-
tal lines so measured, is evidently the horizontal distance
between the stations.
For example, in measuring the
horizontal distance between A
and C, we first place a staff at Jl
and another at 6, in the direction
towards C. Then slide up the
chain on the staff at A until it
becomes horizontal, and note the
distance ah. Then remove the
staves and place them at h and d :
make the chain horizontal, and note the distance cd. Mea-
sure in the same manner the line fC ; and the sum of the
horizontal lines ah, cd and /C, will be equal to AB, the
horizontal distance between Jl and C.
86. We come now to the measurement of angles, and for
this purpose several instruments are used. The one, however,
which affords the most accurate results, and which indeed can
alone be relied on for nice or extensive operations, is called a
Theodolite. This instrument only will be described at present ;
others will be subsequently explained.
OF THE THEODOLITE.
PL 1. The theodolite is an instrument used to measure
horizontal and vertical angles. It is usually placed on a
tripod ABC, which enters by means of a screw the lower
horizontal plate DE, and becomes firmly attached to the body
of the instrument. Through the horizontal plate DE, four
small hollow cylinders are inserted, which receive four screws
with milled heads, that work against a second horizontal
plate, FG. The upper side of the plate DE terminates in a
curved surface, which encompasses a ball, that is nearly a
semi-sphere, with the plane of its base horizontal. This ball,
which is hollow, is firmly connected with the smaller base of
a hollow conic frustrum, that passes through the curved part
5G ELEMENTS OF SURVEYING,
of the plate DE, and screws firmly into the curved part of tVie
second horizontal plate FG.
A hollow conic spindle passes through the middle of the
ball, and the hollow frustrum with which it is connected. To
this spindle, a third horizontal and circular plate HI, caUed
the limb of the instrument, is permanently attached. Within
this spindle, and concentric with it, there is a second spindle,
called the inner, or solid spindle, To this latter, is united a
thin circular plate, called the vernier plate, which rests on the
limb of the instrument, and supports the upper frame-work.
The two spindles terminate at the base of the spherical ball,
where a small screw enters the inner one, and presses a
washer against the other, and the base of the ball. On the
upper surface of the plate FG, rests a clamp which goes round
the outer spindle, and which being compressed by the clamp-
screw K, is made fast to it. This clamp is thus connected with
the plate FG. A small cylinder a, is fastened to the plate FG:
through this cylinder a thumb-screw L passes, and works
into a small cylinder b, connected with the clamp. The
cylinders b and a, admit of a motion round their axes, to
relieve the screw L of the pressure which would otherwise be
occasioned by working it.
Directly above the clamp, is the lower telescope MJST
This telescope is connected with a hollow cylinder, which is
worked freely round the outer spindle, by the thumb-screw P
having a pinion working into a concealed cog-wheel, that is
permanently fastened to the limb of the instrument. By
means of a clamp-screw Q, the telescope is made fast to the
limb, when it will have a common motion with the limb and
outer spindle.
The circular edge of the limb is chamfered, and is generally
made of silver, and on this circle the graduation for horizontal
angles is made. In the instrument described, the circle is cut
into degrees and half degrees ; the degre\es are numbered from
0 to 360.
On the circular edge of the vernier plate, is a small space
of silver, called a vernier ; this space is divided into 30 equal
parts, and numbered from the line marked 0 to the left.
There are two levels attached to the vernier plate, at right
angles to each other, by small adjusting screws; one of them
is seen in the figure. The vernier plate turns freely around
OF THE THEODOLITE. 57
with the inner spindle. It is made fast to the limb of the
instrument by the damp-screw S ; after which the smaller
motions are made by the tangent-screw T.
There is a compass on the vernier plate, that is concentric
with it, the use of which will be explained under the head
compass.
The frame-work which supports the horizontal axis of the
vertical semicircle UV and the upper telescope, with its
attached level, rests on the vernier plate, to which it is made
fast by three adjusting screws, placed at the angular points of
an equilateral triangle. The vertical semicircle UV, is called
the vertical limb ; its motions are governed by the thumb-screw
Z, which has a pinion, that works with the teeth of the ver-
tical limb. On the face of the vertical limb, opposite the
thumb-screw Z, the limb is divided into degrees and half
degrees : the degrees are numbered both ways from the line
marked 0. There is a small plate resting against the gradu-
ated face of the vertical limb, called the vernier ; it is divided
into 30 equal parts, and the middle line is designated by 0.
On the other face of the vertical limb, are two ranges of
divisions, commencing at the 0 point, and extending each way
45". The one shows the vertical distance of any object to
which the upper telescope is directed, above or below the
place of the instrument, in lOOth parts of the horizontal
distance : the other, the difference between the hj'^pothenusal
and base lines : the hypothenuse being supposed to be divided
into one hundred equal. parts: therefore, by mere inspection,
we can ascertain the number of links, which must be sub-
tracted from every chain of an oblique line, to reduce it to
a true horizontal distance.
The supports of the upper telescope are called the wyes,
and designated Y^s. Two loops, turning on hinges, pass over
the telescope, and are made fast by the pins c and d; these
loops confine the telescope in the Y^s. By withdrawing the
pins, and turning the loops on their hinges, the telescope may
be removed for the purpose of being reversed in position ; and
in both situations, the telescope can be revolved in the F's
about its axis.
In the telescopes attached to the theodolite, are two prin-
cipal lenses, one a,t each end. The one at the end Avhere
58 ELEMENTS OF SURVEYING.
llic eye is placed, is called the eyeglass, the other the object
glass.
In order that the axis of the telescope may be directed to
an object with precision, two spider's lines, or small hairs, are
fixed at right angles to each other, and placed within the
barrel of the telescope, and at the focus of the eyeglass.
The vertical hair is moved by two small horizontal screws,
one of which, /, is seen in the figure ; and the horizontal
hair, by two vertical screws, g and h.
Before using the theodolite, it must be properly adjusted.
The adjustment consists in bringing the different parts to their
proper places.
The line of collimation, is the axis of the telescope. With
this axis, the line drawn through the centre of the eyeglass,
and the intersection of the spider's hues, ought to coincide.
First adjustment. The first adjustment regards the line
of coUimation: it is, to fix the intersection of the spider^s lines m
the axis of the telescope.
Having screwed the tripod to the instrument, extend the
legs, and place them firmly. Then loosen the clamp-screw *S
of the vernier plate, and direct the telescope to a small, well-
defined, and distant object. By means of a small pin i, on
the under side of the telescope, slide the eyeglass till the
spider's lines are seen distinctly ; then with the thumb-screw
X, which forces out and draws in, the object glass, adjust this
glass to its proper focus, when the object, as well as the
spider's lines, will be distinctly seen: after which, by the
tangent-screw T and the thumb-screw Z, bring the inter-
section of the spider's lines exactly upon a well-defined point
of the object.
Having done this, revolve the telescope in the Y^s, half round,
when the attached level mn, will come to the upper side.
See, in this position, if the horizontal hair appears above oi
below the point, and in either case, loosen one, and tighten
the other, of the two screws that work the horizontal hair,
till the horizontal hair has been carried over half the space
between its last position and the observed point. Carry the
telescope back to its place ; direct again the intersection of the
spider's lines, to the point, and repeat the operation till the
horizontal hair neither ascends nor descends, while the tele-
OF THE THEODOLITE. 59
scope is revolved. A siHiilar process will arrange the vertical
hair, and the line of colliniation is then adjusted.
Second adjustment. — To make the axis of the attached
level of the upper telescope, parallel to the line of collimation.
Turn the vernier plate, till the telescope comes directly over
two of the levelling screws, between the plates DE and FG.
Turn these screws contrary ways, keeping them firm against
the plate FG, till the bubble of the level mn, stands at the
middle of the tube. Then, open the loops, and reverse the
telescope. If the bubble still stands in the middle of the
tube, the axis of the tube is horizontal ; but if not, it is in-
clined, the bubble being at the elevated end. In that case,
by means of the small vertical screws m and n, at the ends
of the level, raise the depressed end, or depress the elevated
one, half the inclination ; and then, with the levelling screws,
bring the level into a horizontal position. Reverse the tele-
scope in the F's, and make the same correction again ; and so
on, until the bubble stands in the middle of the tube, in both
positions of the telescope : the axis of the level is then hori-
zontal. Let the telescope be now revolved in the Y^s. If the
bubble continue in the middle of the tube, the axis of the
level is not only horizontal, but also parallel to rh • tine of
collimation. If, however, the bubble recede from its centre,
the axis of the level is inclined to the line of collimation, and
must be made parallel to it by means of two small screws,
(one of which is seen at p,) which work horizontally. By
loosening one of them, and tightening the other, the level is
soon brought parallel to the line of collimation, and tiien, if the
telescope be revolved in the F'5, the bubble will continue in
the middle of the tube.
It is difficult to make the first part of this' adjustment, while
the axis of the level is considerably inclined to the liiic of
collimation ; for, if the level were truly horizontal in one
position of the telescope, when the telescope is reversed, the
bubble would not stand in the middle of the tube, except
in one position of the level. This suggests the necessity of
making the first part of the adjustment with tolerable accu-
racy; then, having made the second with care, let the first
be again examined, and proceed thus till the adjustment is
completed
60 ELEMENTS OF SURVEYING.
Third adjustment. — To make the limb of the instrument
horizontal, or, to make the common axis of the limb and vernier
plate truly vertical.
This adjustment is effected, partly by the levelling screws,
and partly by the thumb-screw Z. Turn the vernier plate,
until the upper telescope comes directly over two of the level-
ling screws, then turn them contrary ways, till the upper tel-
escope is horizontal ; after which, turn the vernier plate 180°,
and if the bubble of the level remains in the middle of the
tube, one line of the limb is horizontal. But if the bubble
recede from the centre of the level, raise the lower, or depress
the upper end, one-half by the levelling screws, the other by
the thumb-screw Z, till it is brought into a horizontal posi-
tion. Turn the vernier plate again 180°, and if the level
be not then horizontal, make it so, by dividing the error as
before, and repeat the operation until the line of the limb
is truly horizontal. Then turn the vernier plate 90", and
level as before. The limb ought now to be truly horizontal ;
but lest the first horizontal line may have been changed, in
obtaining the second, it is well to bring the telescope and
level two or three times over the levelling screws, until an
entire revolution can be made without displacing the bubble
from the middle of the tube. As this can only be the case
when tlie level revolves around a vertical line, it follows that
the limb will then be horizontal, and the axis of the instru-
ment vertical.
This adjustment being completed, the levels of the vernier
plate are readily made parallel with it, by means of the small
screws at their extremities. The three levels being then hori-
zontal, and perpendicular in direction to the axis of the theo-
dolite, the bubbles will retain the middle places in tlie tubes,
during an entire revolution of the vernier plate, or of the
limb and vernier plate together.
But the levels of the vernier plate may be made parallel
with the limb, and the limb made truly horizontal, without
the aid of the upper level.
Let the upper telescope be placed directly over two of the
levelling screws. One of the levels of the vernier plate will
then be parallel to the line of these two screws, and the other
level will be at right angles to this line, or parallel to the line
of the other two levelling screws. In thi-s situation, let the
OF THE THEODOLITE. 61
levels be made horizontal, by means of the levelling screws.
Then turn the vernier plate 180°, and if they both continue
horizontal, the limb is truly level. But if both, or either of
them, be changed from a horizontal position, let the error
be divided between the level and the limb ; and repeat the
operation until the levels will continue horizontal during au
entire revolution : the limb is then horizontal, and the axis
of the instrument truly vertical.
Fourth adjustment. — To make the axis of the vertical
limb truly horizontal, or perpendicular to the axis of the instru-
ment.
Bring the intersection of the spider's lines of the upper
telescope upon a plumb line, or any well-defined vertical
object, and move the telescope with the thumb-screw Z : if
the intersection of the spider's lines continue on the vertical
line, the axis is horizontal.
Or, the adjustment may be effected thus: Direct the inter-
section of the spider's lines to a well-defined point that is
considerably elevated : then turn the vertical limb, until the
axis of the telescope rests on some other well-defined point,
upon or near the ground : reverse the telescope, and turn the
vernier plate 180°; now, if in elevating and depressing the
telescope, the line of collimation passes through the two
points before noted, the axis is horizontal. If it be found, by
either of the above methods, that the axis is not horizontal, it
must be made so by the screws which fasten the frame-work
to the vernier plate.
There are two important lines of the theodolite, the positions
of which are determined with great care by the maker, and
fixed permanently. First, the axis of the instrument is placed
exactly at right angles with the limb and vernier plate ; and
unless it have this position, the vernier plate will not revolve
at right angles to the axis, as explained in the third adjust-
ment. Secondly, the line of collimation of the upper telescope,
is fixed at right angles to the horizontal axis of the vertical
limb. We can ascertain whether these last lines are truly at
right angles, by directing the intersection of the spider's lines
to a well-defined point ; then removing the caps which con-
fine the horizontal axis in its supports, and reversing the
axis : if the intersection of the spider's lines can be made to
bZ ELEMENTS OF SURVEYING.
cover exactly the same point, without moving the vernier
plate, the line of collimation is at right angles to the axis.
If the theodolite be so constructed that either of the Y^s
admits of being moved laterally, so as to vary the angle be-
tween the horizontal axis and the line of collimation, these
lines may be adjusted at right angles to each other, if they
have not been so placed by the maker.
The lower telescope being used merely as a guard, requires
no adjustment, although it is better to make the axis, about
which its vertical motions are performed, horizontal, or per-
pendicular to the axis of the instrument ; and this is easily
effected by means of the two small screws k and /, which
work into the slide A', that is connected with the horizontal
axis.
The theodolite being properly adjusted, the particular uses
of its several parts, and the manner of measuring angles, are
now to be explained.
There are two verniers on the vernier plate, and the points
of them marked 0, are at the opposite extremities of a diam-
eter ; which diameter is the intersection of a vertical plane
passed through the line of collimation, with the vernier plate.
It is important to ascertain the exact arc intercepted on the
limb, between its 0 point, (this being the point from which the
degrees are numbered), and this diameter, for any position
which it may assume. The limb being divided to half degrees,
if we had only the line marked 0 on the vernier, to guide
us, the place of the extremity of the diameter could only be
ascertained with certainty to half degrees, as there would be
no means of determining its exact position, when it falls
between the lines of division on the limb. But the vernier
affords results much more accurate. As most instruments
for the measurement of angles have verniers, it will perhaps
be best to explain their use generally.
First. — Count carefully the number of spaces into which
the vernier is divided : this number is one less than the num-
ber of lines which limit them.
Secondly. — Turn the vernier till the line at one extremity
coincides with a line of the graduated limb,, when the line
at the other extremity will also coincide with a line of the
graduated limb ; for the sum of the spaces on the vernier ia
OF THE THEODOLITE. 63
always exactly equal to a given number of spaces on the
limb ; then count the number of spaces on the limb which
the vernier covers.
Thirdly. — Examine the limb of the instrument, and ascer
tain into what parts of a degree it is divided, and express one
of those equal parts in minutes.
Let X represent the value of one of the equal spaces of the
vernier, and n their number; then nx will be equal to the
space covered by the vernier. Let a represent the smallest
equal space into which the limb is divided, and m the number
of such spaces covered by the vernier ; then ma will be equal
to the space on the limb covered by the vernier, which is also
equal to nx.
The equation nx=ma is called the equation of the instru-
ment. In this equation,
ma
x=— ;
n
m, a, and n, being known, x can be found, as also the differ-
ence between a and x, which we shall show presently, to be
the smallest certain count of the instrument.
In the theodolite, m = 29, a==30' andn=30 hence ;
x = 'l^^ = 20';
30
and a—x = 30' — 29' = l',
the excess of a space on the limb over a space on the vernier.
Fig. 2. Let AB be a portion of the limb of the instru-
ment, and CED the vernier in one of its positions, its 0
point coinciding with the line marked 10 on the limb. Now,
since each space of the vernier is less by l' than each space
of the limb, the first line on the left of 0, will be l' to ihe
right of the first line on the left of the 1 0 on the limb ; and if
the vernier plate be moved l' towards the left, these lines will
coincide, and the second line from 0 will then be 1' to the right
of the second line from 10 ; if the vernier be moved another
minute, these last lines will coincide. The vernier would then
show 100 2'.
If the vernier plate be turned still farther, till the thirrl,
fourth, fifth, &c. lines coincide, it is plain, that the 0 point of
the vernier will have passed the line 10 on the limb, by as
many minutes as there are lines of the vernier which shall
have coincided with Imes of the limb. When the last Ime
64 ELEMENTS OF SURVEYING.
of the vernier coincides with a line of the limb, the vernier
will have been moved 30', or half a degree; and the 0 point
will at the same time coincide with a line of the limb, and
show 10° 30'.
The general rule for reading the angle for any position of
the vernier may now be stated.
When the 0 line of the vernier coincides with a line of the
limb, the arc is easily read from the limb ; but when it falls
between two lines, note the degrees and half degrees up to
the line on the right ; then pass along the vernier till a line is
found coinciding with a line of the limb : the number of this
line from the 0 point, indicates the minutes which are to be
added to the degrees and half degrees, for the entire angle.
To measure a horizontal angle with the theodolite.
Place the axis of the instrument directly over the point at
which the angle is to be measured. This is effected by means
of a plumb, suspended from the plate which forms the upper
end of the tripod.
Having made the limb truly level, place the 0 of the ver-
nier at 0 or 3600 of the Umb, and fasten the clamp-screw S
of the vernier plate. Then, facing in the direction between
the lines which subtend the angle to be measured, turn the
limb with the outer spindle, until the telescope points to the
object on the left, very nearly. Clamp the limb with the
ciamp-screw K, and by means of the tangent screws L and
Z, bring the intersection of the spider's lines to coincide
exactly with the object.
Having loosened the clamp-screw Q of the lower telescope
MJ^, direct it with the thumb-screw P to the same object at
which the upper telescope is directed ; then tighten the clamp-
screw Q. This being done, loosen the clamp-screw /S of the
vei niei plate, and direct the telescope to the other object : the
arc imssed over by the 0 point of the vernier, is the measure
of the angle sought.
The lower telescope having been made fast to the limb,
will indicate any change of its position, should any have taken
place ; and, as the accuracy of the measurements depends on
the fixedness of the limb, the lower telescope ought to be
often examined, and if its position has been altered, the limb
must be brought back to its place by the tangent-screw L.
OP THE THEODOLITE. 65
It is not necessary to place the 0 point of the vernier at the
0 point of the limb, previously to commencing the measure-
ment of the angle, but convenient merely ; for, whatever be
the position of this point on the limb, it is evident that the arc
which it passes over is the true measure of the horizontal
angle. If, therefore, its place be carefully noted for the first
direction, and also for the second, the difference of these two
readings will be the true angle, unless the vernier shall have
passed the 0 point of the limb, in which case the greater read-
ing must be subtracted from 360", and the remainder added
to the less.
To measure a vertical angle.
In Fig. 3, AB represents a view of the vertical limb oppo-
site the thumb-screw Z, and ED is the vernier. The 0
point of this vernier is at tlie middle division line, and fifteen
spaces lie on each side of it. The relation which exists be-
tween the spaces on the limb and those of the vernier, is the
same as that between the divisions of the horizontal limb and
its vernier, and the degrees and half degrees are read in the
same manner : the angles of elevation being read from the 0
of the limb towards the right, and those of depression in the
contrary direction. For the minutes, we pass along the ver-
nier in tlie direction in which the degrees are counted, and if
we reach the extreme line, which is the fifteenth, without
finding a coincidence, we must then pass to the other extre-
mity of the vernier, and look along towards the 0 point till
two lines are found to coincide : the number of the line on the
vernier will show the minutes. The lines of the vernier are
numbered both ways from the 0 point, and marked 5, 10, 1 5,
to one extremity, and correspondingly from the other extre
mity 15, 20 and 25, to the 0 point again. The upper range
shows the minutes for angles of elevation, and the lower
range for those of depression. The vernier in Fig. 3 stands
at 2" 15' of depression. Had the 15th line at the left,
passed the short line with which it now coincides, we should
pass to the line 15, on the lower range to the right, and then
count towards the 0 to the left.
The first thing to be done, is to ascertain the point of the
vertical limb at which the 0 point of the vernier stands, when
the line of collimation of the upper telescope, together with
66 ELEMENTS OF SURVEYING.
its attached level, is truly horizontal. This is called the true
0 of the limb.
If the instrument be accurately constructed, and the parts
have not been disarranged, this point is the 0 point of the
hmb. This, however, is easily ascertained by turning the limb
till the O's correspond, and then examining if the upper level
be truly horizontal. If not, direct the telescope to a distant
and elevated object, and read the degrees on the vertical
limb. Turn the vernier plate 180", reverse the telescope,
direct it a second time to the same point, and read the arc on
the vertical limb. The half difference of these two readings,
counted from the 0 point of the limb, in the direction of the
greater arc read, gives the true 0 point of the vertical limb ;
that is, the point at which the 0 of the vernier stands when
the line of collimation is horizontal.
Suppose for example, that we had directed the telescope to
a point and found the 0 of the vernier to stand at 10° of ele-
vation. If we now reverse the telescope, it ought to incline
at an equal angle of depression. If then we turn the whole
180°, and then raise the depressed end of the telescope with
the thumb-screw Z", until it is directed to the same point as
before, the 0 ought to stand at 10°. If it shows a less arc,
the true 0 is between the 0 of the limb and the first arc read ;
if a greater, it is on the other side, and the difference divided
by two will indicate the exact 0 point. The half difference
thus found is called the correction. When the true o falls
between the marked 0 and the eyeglass, the correction is to
be subtracted from the arc read, for angles of elevation, and
added, for angles of depression ; and the reverse when it falls
on the other side. The eyeglass is supposed to be over the
thumb-screw Z, as in the plate.
These preparatory steps being taken, let the axis of the
telescope be directed to any point either above or below the
plane of the limb, and read the arc indicated by the 0 of the
vernier. To the arc so read apply the proper correction, if
any, and the result will be the true angle of elevation or de-
pression.
87. Having explained the preliminary principles, it only
remains to apply them to the measurement of Heights and
Distances.

be estimated : then, if we suppose
DC to be a vertical line, it will re-
present the required distance.
C3 ELEMENTS OF SURVEYING.
Measure any horizontal base line, as B*B. ; and at the ex-
tremities B and A, measure the horizontal angles CBA and
CAB. Measure also, the angle of elevation DBC.
Then in the triangle CBA there will be known, two angles
and the side AB ; the side BC can therefore be determined.
Having found BC, we shall have, in the right-angled triangle
DBC, the base BC and the angle at the base, to find the
perpendicular DC, which measures the altitude of the point
D above the horizontal plane BC.

Remark I. It might, at first, appear that the solution which
we have given, requires that the points B and A should be in
the same horizontal plane, but it is entirely independent of
such a supposition.
HEIGHTS AND DISTANCES. 69
For, the horizontal distance, which is represented by BA,
is the same, whether the station Jl is on the same level with
J5, above it, or below it (Art. 74). The horizontal angles
CAB and CBA are also the same, so long as the point C is in
the vertical line DC (Art. 75). Therefore, if the horizontal hne
through A should cut the vertical line DC, at any point as E,
above or below C, AB would still be the horizontal distance
between B and A, and .^JE which is equal to AC, would be
the horizontal distance between A and C.
If at A, we measure the angle of elevation of the point D,
we shall know in the right angled DAE, the base AE, and
the angle at the base ; from which the perpendicular DE can
be determined.
Let us suppose that we had measured the angle of elevation
DAE, and found it equal to 20° 15'.
First: In the triangle BAC, to find AC or its equal AE,
As sin C . . 42° 08' ar. comp. .

Now, since DC is less than DE, it follows that the station
B is above the station A. That is,
JDE-i)C = 283.66 -2 18.64= 65.02 =J5:C,
which expresses the vertical distance that the station B is
above the station A.
Remark II. It should be remembered, that the vertical
distance which is obtained by the calculation, is estimated from
a horizontal hne passing through the eye at the time of
observation. Hence, the height of the instrument is to be
added, in order to obtain the true result.
70 ELEMENTS OF SURVEYING.
SECOND METHOD.
90. When the nature
of the ground will ad-
mit of it, measure a base
line AB in the direction
of the object D. To
do this, it will be well to A ^^^^w^^v^^^^^-jy -
place the theodolite at Jl^ and range the chain staves by means
of the upper telescope. Having measured the base, measure
with the instrument the angles of elevation at A and B.
Then, since the outward angle DBC is equal to the sum
of the angles A and ADB, it follows, that the angle ADB
is equal to the difference of the angles of elevation at A and
B. Hence, we can find all the parts of the triangle ADB.
Having found DB, and knowing the angle DBC, we can find
the altitude DC.
This method supposes that the stations .^ and 5 are on
the same horizontal plane ; and therefore can only be used
when the line AB is nearly horizontal.
Let us suppose that we have measured the base line, and
the two angles of elevation, and

PROBLEM III.
To determine the perpendicular distance of an object below a given
horizontal plane,
91. Suppose C to be directly
over the given object, and A the
point through which the horizontal
plane is supposed to pass.
Measure a horizontal base line
AB, and at the stations A and B
conceive the two horizontal lines . ,
.^C, BC, to be drawn. The oblique ^'^ ' ^"^^4^
lines from A and B to the object will be the hypothenuse?
of two right-angled triangles, of which AC, BC, are the
bases. The perpendiculars of these triangles will be the
distances from the horizontal lines AC, BC, to the object.
If we turn the triangles about their bases AC, BC, until
they become horizontal, the object, in the first case, will fall
at C, and in the second at C".
Measure the horizontal angles CAB, CBA, and also the
angles of depression C'AC, C"BC.
Let us suppose that we have

Remark. In measuring a base line, if great accuracy is
required, the theodolite should be placed at one extremity,
and the telescope directed to the other, and the alignment of
the staves made by means of the intersection of the spider's
lines. If the highest degree of accuracy is necessary, the
base line should be measured with rods, which admit of being
adjusted to a horizontal position by means of a spirit level.

OF MEASUREMENTS WITH THE TAPE OR CHAIN ONLY.
92. It often happens that instrmnents for the measurement
of angles cannot be easily obtained ; we must then rely
entirely on the tape or chain.
We now propose to explain the best methods of determining
distances, without the aid of instruments for the measurement
of horizontal or vertical angles.

perpendicular at a given point, to a given right line.

the line BC, two equal distances AB, AC,
one on each side of the point A. Take a b A C
portion of the chain or tape, greater than ^^B, and place one
extremity at B, and with the other trace the arc of a circle on
the ground. Then remove the end which was at B, to C,
and trace a second arc intersecting the former at D. The
straight line drawn through D and A will be perpendicular
to jBC at A.

siderably greater than the distance _^

ties, the one at B and the other at JJ
C, Then, taking the chain by the middle point, stretch it
tightly on either side of BC, and place a staff at D or £ :
then will DJlE be the perpendicular required.

measure a distance CA equal to 8.

chain at Jl^ and carry it round until it falls on the line AE
at F. Then place a staff at F, and JIDF will be a right
angle, being an angle in a semi-circle.
97. There is a very siinple instrument, used exclusively
in laying off right angles on the ground, which is called the
SURVEYING CROSS.
PI. 2. Fig. 1. This instrument consists of two bars, JIB
and CD, permanently fixed at right angles to each other,
and firmly attached at ^ to a pointed staff, Avhich serves as
a support. Four sights are screwed firmly to the bars, by
means of the screws a, 6, c, and d.
As the only use of this instrument is to lay off right angles,
it is of the first importance that the lines of sight be truly
at right angles. To ascertain if they are so, let the bar AB
be turned until its sights mark some distinct object ; then
look through the other sights and place a staff on the line
which they indicate : let the cross be then turned until the
sights of the bar AB come to the same line : if the other
sights are directed to the first object, the lines of sight are
exactly at right angles.
The sights being at right angles, if one of them be turned
in the direction of a given line, the other will mark the direc-
tion of a line perpendicular to it, at the point where the
instrument is placed.
PROBLEM II.

Having stationed a person at A, measure along the perpen-
dicular FF until the forward staff is aligned on the line AC :
then measure the distance AE. Now, by similar triangles,
we have

HEIGHTS AND DISTANCES. 77
in which all the terms are known except AD, which may,
therefore, be considered as foimd. The distance AD being
laid off from A, the pomt D, at which the perpendicular
CD meets AB, becomes known. If we wish the length of
the perpendicular, we use the proportion
AE : EF : : AC : CD,
in which all the terms are known, excepting CD : there-
fore, CD is determined.
PROBLEM III.
To determine the horizontal distance from a given point to an
inaccessible object.
99. Let A be an inaccessible ob-
ject, and E the point from which I
the distance is to be measured.
At E lay off the right angle AED, --^^
and measure in the direction ED, U
any convenient distance to D, and » ^f-r
place a staff at D. Then measure ^..x" ;
from E, directly towards the object D F ■ '''
A, a distance EB of a convenient length, and at B lay off
a line BC perpendicular to EA. Measure along the line
BC, until a person at D shall range the forward staff on the
line DA. Now, DF is known, being equal to the difference
between the two measured lines DE and CB. Hence, by
similar triangles,
DF : FC : : DE : EA,
in which proportion all the terms are known, except the
fourth, which may, therefore, be regarded as found : hence,
EA is determined.
SECOND METHOD.

EB perpendicular to the line

At B lay off the right angle

while a second person at B aligns it on BE : the staff will
thus be fixed at C. Then measure the distance BC.
The two triangles BCD and CAE being similar, we have,
BC : BD : : CE : EA,
m which all the terms are known, except the fourth, which
may, therefore, be regarded as found.
THIRD METHOD.
101. Let B be the given point,
and A the inaccessible object, it
is required to find BA.
Measure any horizontal base
line, as BC. Then, having placed
staves at B and C, measure any
convenient distances BD and CE,
such that the points D, B and A,
shall be in the same right line,
as also, the points E, C and A ;
then rrieasure the diagonal lines DC and EB.
Now, in the triangle BEC, the three sides are known,
therefore, the angle ECB can be found. In the triangle
CDB, the three sides are also known, therefore the angle
CBD can be determined. These angles being respectively
subtracted from 180°, the two angles ACB and ABC be-
come known ; and hence, in the triangle ABC, we have
two angles and the included side, to find the side BA.
PROBLEM IV.
To find the altitude of an object, when the distance to the

then, CD becomes known.
If the line AC cannot be measured, on account of inter-
vening objects, it may be determined by calculation, as in
the last problem, and then, having found the horizontal dis-
tance, the vertical line is readily determined, as before.
CHAPTER III.
Of the area or content of ground. — Of laying out and
dividing land.
103. We come next to the determination of the area or
content of ground.
The surface of the ground being, in general, broken and
uneven, it is impossible, without great trouble and expense,
to ascertain its exact area or content. To avoid this incon-
venience, it has been agreed to refer every surface to a
horizontal plane : that is, to regard all its bounding lines as
horizontal, and its area as measured by that portion of the
horizontal plane which the boundary lines enclose.
For example, if ABCD were a
piece of ground having an uneven
surface, we should refer the whole to
a horizontal plane, and take for the
measure of the area that part of the
plane which is included between the
bounding lines AB, BC, CD, DA.
In estimating land in this manner, the sum of the areas
of all the parts into which a tract may be divided, is equal
to the area estimating it as an entire piece : but this would
not be the case if the areas of the parts had reference to
the actual surface, and the area of the whole were calcu-
lated from its bounding lines.

ELEMENTS OF SURVEYING.
104. The unit of a quantity is one of the equal parts of
which the quantity is composed {Arilh. In. VI). Thus, a
Jine of three feet in length is made up of' three single feet,
and of this line, 1 foot is the unit. The unit of a line may
be 1 foot, 1 yard, 1 rod, 1 chain, or any other known distance.
If, on the unit of length, a square be described, it will
form the unit for computing areas.
1 foot.
Thus, is 1 square foot,
1 square yard, or 9 square feet.
1 yard=3 foet.
I square chain, or 16 square rods. .
1 chain:
=4 rn
ds.
Thus it is seen that there are two kinds of quantity to be
considered, viz. lines, and areas or surfaces ; and each kind
has its own unit of measure.
When, therefore, the linear measures of ground are feet,
yards, rods, or chains, the superficial measures will be square
feet, square yards, square rods, or square chains ; and the
number expressing the area will be nothing else than the
number of times which the unit of superficial measure is
contained in the land measured.
It has been already observed (Art. 83), that Gunter's chain
of four rods or 66 feet in length, and which is divided into
100 links, is the chain in general use among surveyors. We
shall, therefore, take the length of this chain for the unit
of linear measure.
CONTENT OP GROUND.

105. An acre is a surface equal in extent to 10 square
chains ; that is, equal to a rectangle of which one side is
ten chains, and the other side one chain.
One-quarter of an acre, is called a rood.
Since the chain is 4 rods in length, 1 square chain con-
tains 16 square rods; and therefore, an acre, which is 10
square chains, contains 160 square rods, ar i a rood contains
40 square rods. The square rods are called perches.
106. Land is generally computed in acres, roods, and perches,
which are respectively designated by the letters A. R. P.
When the linear dimensions of a survey are chains or links,
the area will be expressed in square chains or square links,
and it is necessary to form a rule for reducing this area to
acres, roods, and perches. For this purpose, let us form the
following
TABLE.
1 square chain = 10000 square links.
1 acre = 10 square chains = 100000 square links.
1 acre = 4 roods = 160 perches.
1 square mile = 6400 square chains = 640 acres.
Now, when the linear dimensions are links, the area will
be expressed in square links, and may be reduced to acres
by dividing by 100000, the number of square links in an
acre : that is, by pointing off five decimal places from the
right hand.
If the decimal part be then multiplied by 4, and five places
of decimals pointed off from the right hand, the figures to
the left will express the roods.
If the decimal part of this result be now multiplied by 40,
and five places for decimals pointed off, as before, the figures
to the left will express the perches.
If one of the dimensions be in links, and the other in
chains, the chains may be reduced to links by annexing two
ciphers : or, the multiplication may be made without annex-
ing the ciphers, and the product reduced to acres and deci-
mals of an acre, by pointing off three decimal places at the
right hand.
When both the dimensions are in chains, the product is
reduced to acres by dividing by 10, or pointing off one deci-
mal place. ' ^
82 ELEMENTS OF SURVEYING.
From v/hich we conclude ; that,
1st. If links be multipUed by links^ the product is reduced
to acres by pointing off five decimal places from the right hand.
'2d. If chains be multiplied by links, the product is reduced
to acres by pointing off three decimal places from the right hand.
3d. If chains be multiplied by chains, the product is reduced
to acres by pointing off one decimal place from the right hand.
107. Since there are 16.5 feet in a rod, a square rod is
equal to . 16.5 x 16.5=272.25 square feet.
If the last number Irr multiphed by 160, we shall have
272.25 X 160 = 43560 =the square feet in an acre.
Since there are 9 square feet in a square yard, if the las*
iiumber be divided by 9, we obtain
4840= the number of square yards in an acre.

Remark. Instead of measuring the four sides of the

Remark II. In determining the content of ground, in
the examples which have been given, the linear dimen-

If the linear dimensions were taken in terms of any other
unit, they may be readily reduced to chains. For, a chain
is equal to 4 rods, equal to 22 yards, equal to 66 feet

OF LAYING OUT AND DIVIDING LAND.
116. The surveyor is often required to lay off a given
quantity of land, in such a way that its bounding lines shall
form a particular figure, viz., a square, a rectangle, a tri-
angle, &c. He is also often called upon to divide given
pieces of land into parts containing given areks, or bearing
certain relations with each other.
The manner of making such divisions must always de-
pend on a judicious application of the principles of g:eom-
etry to the particular case.
90 ELEMENTS OF SURVEYING.
If, for example, it were required to lay out an acre of
ground in a square form, it would first be necessary to
find, by calculation, the side of such a square, and then to
trace, on the ground, four equal lines at right angles to each
other.
PROBLEM I.
117. To lay out a given quantity of land in a square form.
Reduce the given area to square chains , or square rods
then extract the square root, and the result will be the side oj
the required square. This square being described on the groundy
will be the figure required.
1. To trace a square which shall contain 15.^ oR 12P
First, . 15A = 60 R=2i00 P
Add . . . 12 P; hence,
15*4 OR 12 P=2412 P; the square root of
which is 49.11.
Therefore, if a square be traced on the ground, of which
the side is 49.11 rods, it will be the required figure.
2. To trace a square which shall contain 176^ iR 24P.
First, . 176.^=1760 square chains,
1R= 2.5 " "
24 P= 1.5 " " ; hence,
176.^ iR 24P=1764 square chains: the square
root of which is 42. Hence, if a square be traced on the
ground, of which the side is 42 ch, it will be the required
figure.
PROBLEM II.
118. To lay out a given quantity of land in a rectangular
form, having one of its sides given.
Divide the given area, reduced to square chains or square
rods, by the given side of the required rectangle, and the quo-
tient will be the other side. Then trace the rectangle on the
ground.
1. To lay oflf 240 acres in a rectangular form, one of the
sides being given, and equal to 80 rods.
First, 240.^ = 2400 square chains = 38400 square rods.
Then, 80)38400(480 rods ; which is the required side
of the rectangle.
OF THE COMPASS. 91
119. A great number of similar problems might be pro-
posed. The solution of them does not, however, properly
belong to surveying. The laying out of the ground, and
the tracing of lines, after the figure and area have been
determined, are the only parts which appertain to a practical
treatise. The manner of tracing lines having been already
explained, it seems unnecessary to add the numerous ex-
amples often given under this head of the subject.
. CHAPTER IV.
Of the Surveying Compass. — Of Surveying with the Compass. —
Of the Plane-Tahle.
120. Before considering the principles involved in the
method of surveying now to be explained, it will be neces-
sary to describe the instrument principally used in the field,
and which is called
THE CIRCUMFERENTER, OR SURVEYOR'S COMPASS.
PL 2, Fig. 2. This instrument consists of a compass-box
DCE, a magnetic needle, a brass plate AB, from twelve
to fourteen inches long, two plain sights, AF and J5G, one
of which is more fully shown in Fig. 3 ; and a stand, which
is sometimes a tripod, and sometimes a single staff pointed
with iron at the lower end, so that it may be placed firmly
in the ground.
The open sights, AF and BG, are placed at right angles
to the plate AB, and fastened to it firmly by the screws
a and 6. In each sight there is a large and small aperture
or slit ; the larger aperture being above the smaller in one
of the sights, and below it in the other. A hair or thread
of silk is drawn vertically through the middle of the large
aperture, as shown in Fig. 3.
The compass-box DCE is circular, and generally about
six inches in diameter. At the centre is a small pin, on
which the magnetic needle is poised. This needle, if allowed
92 ELEMENTS OF SURVEYING.
to turn freely around the point of support, will settle to a
state of rest : the direction which it then indicates, is called
the magnetic meridian.
Jn the interior of the compass-box, there is a graduated
circle divided to degrees, and sometimes to half degrees : the
degrees are numbered from the extremities of the diameter
JS*S, both ways to 90".
The length of the magnetic needle is a little less than
the diameter of the graduated circle, so that the needle can
move freely around its centre, within the circle, and its posi-
tions be noted on the graduated arc.
The compass-box is turned about its centre, without moving
the plate AB, by means of the milled screw L: it is fast-
ened to the plate AB, by the screw P.
In using the compass, it is important to ascertain the
exact angle which may be included between the magnetic
meridian and the direction that may be given to the line
drawn through the eye and the sights AF and BG.
To effect this, a small arc HI is described on the bar
ABi having its centre at the centre of the compass-box.
This arc is divided to degrees, and sometimes to the parts
of a degree. A vernier is also used, which is permanently
attached to the compass-box.
When the 0 point of this vernier coincides with the 0
point of the graduated arc HI, the line of the compass-box
marked J^'S, has the same horizontal direction as the line
along which the sights are directed.
Now, supposing the 0 of the vernier to coincide with the
0 of the arc HI, if the end of the needle does not stand
at one of the lines of division of the graduated circle, let
the whole degrees be read. Then, turn the compass-box
by means of the screw L, until the needle points exactly to
the line which marked the whole degrees: the space passed
over by the 0 of the vernier, shows the minutes that are to
be added.
OP SURVEYING WITH THE COMPASS.
121. The line about which the earth revolves is called its
axis; and the two points in which the axis meets the surface
of the earth are called the poles.
WITH THE COMPASS. 93
122. A meridian is a line traced on the surface of the
earth, which would, if sufficiently produced in both direc-
tions, pass through the poles. Hence, all the meridian lines
intersect each other at the two poles.
Tlie poles, however, are so distant from each other, that
no sensible error will arise in supposing the meridians to be
parallel ; and since, in all the surveys made with the compass,
the surface of the ground is regarded as a horizontal plane,
the n^pridians are represented by horizontal and parallel lines.
123. When the compass is placed on its stand,' and the
needle is allowed to settle to a state of rest, the direction it
assumes has been named the magnetic meridian. Although
this line is different from the true meridian, yet in the sur
veys irade with the compass, Ave shall take for the meridian
that line which is determined by the direction of the mag-
netic needle.
124. If the right hand be turned towards the point where
the sun rises, the direction pointed by the farthest end of the
needle is called north; the direction shown by the nearest
end is called south, and the line thus indicated is called a
north and south line, as well as a meridian.
125. A line perpendicular to the meridian is called an east
and west line : the east point being on the right hand, and
the west on the left.
126. A line traced or measured on the ground, is called a
course ; and the angle which this line makes with the meri-
dian passing through the point of
beginning, is called the hearing.
Thus, if we start from the point
A, and measure in the direction
AB, the line AB is the course,
and the angle J>CAB is the bear-
ing.
s
When the course, like AB, falls between the north and
east points, the bearing is read, north 46® east, and is writ-
ten, N 46° E
94
ELEMENTS OF SURVEYING.
Wlien the course, like j2C, falls between the north and
west points, the bearing is read, north 30" west, and is
written, N 30° W.
When the course, like SF,
falls between the south and east
points, the bearing is read, south
70" east, and is written, S 70° E.
When the course, like AD,
falls between the south and west
points, the bearing is read, south
70° west, and is written, S 70°
W.
A course which runs due north, or due south, is desig
nated by the letter N or S : and one which runs due east,
or due west, by the letter E or W.
127. If, after having passed over a course, the bearing
oe taken to the back station, this bearing is called the back
sight, or reverse bearing.
128. The perpendicular distance between the east and west
lines, drawn through the extremities of a course, is called the
northing or southing, according as the course is run towards
the north or south. This distance is also called the difference
of latitude, or simply the latitude, because it shows the dis-
tance which one of the points is north or south of the other.
Thus, in running the course from A
to B, JIC is the difference of latitude,
north.

129. The perpendicular distance be-
tween the meridians passing through the
extremities of a course, is called the de-
parture of that course, and is east or west, ^
according as the course lies on the east or west side of the
meridian passing through the point of beginning.
Thus, in running the course AB, CB is the departure, east.
130. It will be found convenient, in explaining the rules
for surveying with the compass, to attribute to the latitudes
and departures the algebraic signs, -\- and — ; which are
read plus and minus.
We shall, therefore, consider every northing as affected

with the sign -f-j ^^^ every southing as affected with the
sign — . We shall also consider every easting as affected
with the sign +, and every westing as affected with the
sign — .
131. The meridian distance of a point is the perpendicular
let fall on the meridian, from which the distance is estimated.
This meridian is called the assumed meridian. Thus, if the
distance be estimated from NS, BC will be the meridian
distance of the point B.
132. The meridian distance of a Hue, is the distance of the
middle point of that line from an assumed meridian : and is
east or west, according as this point lies on the east or west
side of the assumed meridian. Thus, FG drawn through
the middle point of AB, is the meridian distance of the
line AB.
The sign + will always be given to the meridian distance
of a point or line, when it lies on the east of the assumed
meridian, and the sign — , when it lies on the w^est.
1 33. When a piece of ground is to be surveyed, we begin
at some prominent corner of the field, and go entirely around
the land, measuring the lengths of the bounding lines with
the chain, and taking their bearings with the compass. It
is not material whether the ground be kept on the right hand
or on the left, and all the rules deduced for one of the cases,
are equally applicable to the other. To preserve, however,
an uniformity in the language of the rules, we shall suppose
the land to be always kept on the right hand of the sur-
veyor.
Let ABCD be a piece of ground
to be surveyed, A the point w^here
the w^ork is to be begun, and NS a
meridian.
On a sheet of paper, rule three
columns, as in next page, and head
them stations, bearings, distances.

Place the compass at A and take
the bearing to B^ which is PAB :
suppose this angle has been found
to be 3li°. The bearing from A to
B is then N 3li° W. Enter this B
bearing in the field notes opposite xat
station 1. Then measure the dis-
tance from A to B^ which we will
suppose to be 10 ch, and insert that
distance opposite station 1, in the H
column of distances.
We next take the bearing from B to C^ N 62 f° E, and then
measure the distance J?C = 9 ch 25 1, both of which we insert
in the notes opposite station 2.
At station C we take the bearing to Z), S 36° E, and then
measure the distance CD = 1 ch 60 1, and place them in the
notes opposite station 3.
At D we take the bearmg to .^, S 451® W, and then mea-
sure the distance DA = io ch 40 1. We have thus made all
the measurements on the field which are necessary to deter-
mine the content of the ground.
134. Remark I. The reverse bearing, or back sight, from
B to A, is the angle ABH ; and since the meridians NS and
HG are parallel, this angle is equal to the bearing ^AB.
The reverse bearing is, therefore, S 31^° E.
The reverse bearing from C, is S 62i'' W: that is, it is the
angle ICB=:GBC.
WITH THE COMPASS. 97
And generally, a reverse hearing, or hack sight, is always
equal to the forward hearing, and differs from it in hoth of the
letters by which it is designated.
135. Remark II. In taking the bearings with the com-
pass, there are two sources of error. 1st. The inaccuracy of
the observations : 2d. Local attractions, or the derangement
which the needle experiences when brought into the vicinity
of iron-ore beds, or any ferruginous substances.
To guard against these sources of error, the reverse bearing
should be taken at every station : if this and the forward
bearing are of the sartie value, the work is probably right ;
but if they differ considerably, they should both be taken
again.
136. Remark III. In passing over the course AB, the
northing is found to be HB, and the departure, which is west,
is represented by AH. Of the course BC, the northing is
expressed by BG, and the departure, which is east, by GC.
Of the course CD, the southing is expressed by CI, and the
departure, which is east, by CF. Of the course DA, the
southing is expressed by KA, and the departure, which is west,
by DK. It is seen from the figure, that the sum of the
northings is equal to HB-{-BG = IIG ; and that the sum of
the southings is equal to CI-\-KA = PA = HG : hence, the sum
of the northings is equal to the sum of the southings.
If we consider the departures, it is apparent that the sum
of the eastings is equal to GC-\-CF=GF ; and that the sum
of the westings is equal to AH-\-DK= GF : hence also, the
sum of the eastings is equal to the sum of the westings. We
therefore conclude, that when any survey is correctly made,
the sum of the northings will he equal to the sum of the southings,
and the sum of the eastings to the sum of the westings.
It would indeed appear plain, even without a rigorous de-
monstration, that after having gone entirely round a piece of
land, the distance passed over in the direction due north, must
be equal to that passed over in the direction due south ; and
the distance passed over in the direction due east, equal to
that passed over in the direction due west.
Having now explained the necessary operations on the
field, we shall proceed to show the manner of computing the
content of the ground. We shall first explain

98 ELEMENTS OF SURVEYING,
THE TRAVERSE TABLE.
137. This table shows the difference of latitude, and the
departure, corresponding to any bearing, aftd for courses less
than 100.
Let JIB denote any course, NS the t^
meridian, and N.^jB the bearing of AB.
Then will AC h& the difference of lati-
tude, and BC the departure. vAv:
It is evident that the course, the cKffer-
ence of latitude, and the departure, are
respectively, the hypothenuse, tlie base,
and the perpendicular of a right-angled ^
triangle, of which the bearing is the angle at the base.
If there he two hearings, which are complements of each other,
or of which the sum is 90°, the difference of latitude correspond-
ing to the one, will he the departure of the other, and reciprocally.
For, if BC were a meridian, CBA which is the complement
of CAB, would be the bearing of BA ; CB would be the
difference of latitude, and CA would be the departure.
In the traverse table, the figures at the top and bottom
of each page, show the bearings to degrees and parts of a
degree ; and the columns on the left and right, the distances
to which the latitudes and departures correspond.
If the bearing is less than 45°, the angle will be found at
tlie top of the page ; if greater, at the bottom. Then, if the
distance is less than 50, it will be found in the column "dis-
tance," on the left hand page ; if greater than 50, in the
corresponding column of the right hand page. The table is
calculated only to quarter degrees, for the bearings cannot
be relied on to smaller parts of a degree.
The latitudes or departures of courses of different lengths,
but which have the same bearing, will be proportional to the
lengths of the courses. Thus, in the last figure, the lati-
tudes AG, AC, or the departures GF, CB, are to each other
as the courses AF, AB.
Therefore, when the distance is greater than 100, it may
be divided by any number w^hich will give an exact quo-
tient, less than 100: then the latitude and departure being
WITH THE COMPASS. 90
found and multiplied by the divisor, the products will be the
latitude and departure of the whole course. It is also plain,
that the latitude or departure of two or more courses, hav-
ing the same bearing", is equal to the sum of the latitudes
or departures of the courses taken separately.
Hence, if we have any number greater than lOO, as 614,
we have only to regard the last figure as a cipher, and recol-
lect that, 610-}-4 = 614 ; and also, that the latitude and de-
parture of 610, are ten times greater, respectively, than the
latitude and departure of 61 : that is, equal to the latitude
and departure of 61 multiplied by 10, or with the decimal
point removed one place to the right.
I. To find the latitude and departure for the bearing 29i",
and the course 614.
Latitude for 610 . . 530.90

Latitude for 614 . . 534.38
Departure for 610 . . 300.40
Departure for 4 . . 1.97
Departure for 614 . . 302.37
In this example, the latitude and departure answering to
the bearing 29|°, and to the distance 61, are first taken from
the table, and the decimal point removed one place to the
right : this gives the latitude and departure for the distance
610; the latitude and departure answering to the same bear-
ing and the distance 4, are then taken from the table and
added.
2. To find the latitude and departure for the bearing 62^*,
and the course 7855 chains.
Latitude for 7800 . 3602.00
Latitude for 55 . . 25.40

Departure for 7800 . 6919.00
Departure for 55 . . 48.79
Departure for 7855 . 6967.79
Remark. When the distances are expressed in whole
numbers and decimals, the manner of finding the latitudes
and departures is still the same, except in pointing oflf the
places for decimals : but this is not diflScult, when it is re-
membered that the column of distances in the table, may be
regarded as decimals, by removing the decimal point to the
left in the other columns.

Of Balancing the work.
138. The use of the traverse table being explained, we
can proceed to compute the area of the ground.
The field notes having been completed, rule a new table,
as below, with four additional columns, two for latitude, and
two for departure.
Then find, from the traverse table, the latitude and de-
parture of each course, and enter them in the proper columns
opposite the station.
Then add up the column of northings, and also the column
of southings : the two sums should be equal to each other.
If they are not, subtract the less from the greater, and the
remainder is called the error in latitude. This error takes the
name of that column which is the least. For example, if
the sum of the northings is less than the sum of the south-
ings, the error is called, error in northing : but if the sum of
the southings is less than the sum of the northings, the error
is called, error in southing. We find the error for eacli par-
ticular course by the following proportion.
As the sum of the courses
Is to the error of latitude,
So is each particular course
To its correction.
The error of each course, thus found, may be entered in
a separate column; after which, add it to the latitude of the
course, when the error and latitude are of the same name, but
subtract it, when they are of different names. This will make
the sum of the northings equal to the sum of the southings,
and is called balancing the work. The northings and south-
ings, thus corrected, are entered in columns on the right,
under the head, balanced. Having done this, balance the
eastings and westings in the very same manner. The dif-
ference between their sums, is called the error in departure.

139. Remark I. In finding the error in latitude or de-
parture, for a particular course, the last figure is sometimes
doubtful ; in which case it is best to mark it, as in the third
proportion for error in latitude, and the first for error in depar-
ture ; and then, if the figures taken do not balance the work,
let each be increased or diminished by 1.
140. Remark II. It has already been observed (Art. 136),
that if the measurements on the field are correctly made, the
sums of the northings and southings will be equal to each
other, as also those of the eastings and westings. It is the
opinion of some surveyors, that when the error in latitude or
departure exceeds one link for every five chains of the courses,
the field notes ought not to be relied on. This, perhaps, is a
higher degree of accuracy than can be attained. The error,
however, should always be made considerably less than one
link to a chain.
102 ELEMENTS OF SURVEYING.
Of the double meridian distances of the courses.
141. After the work has been balanced, the next thing
to be done is to calculate the double meridian distance of
each course.
For this purpose, a meridian line is assumed, lying either
wholly without the land, or passing through any point within
it. It is, however, most convenient to take that meridian
which passes through the most easterly or westerly station of
the survey ; and these two stations are readily determined by
inspecting the field notes.
Having chosen the meridian, let the station through which
it passes, be called the principal station^ and the course which
begins at this point, the first course. Care, however, must be
taken, not to confound this with the course which begins at station
1, and which is the first course that is entered in the field notes.
It has already been remarked (Art. 132), that all depar-
tures in the direction east, are considered as plus, and all
departures in the direction west, as minus : then, through
whatever station of the survey the assumed meridian be taken,
we shall have for the calculation of the double meridian dis-
tances, the following
RULE.
I. The double meridian distance of the first course is equal
to its departure.
II. The double meridian distance of the next course is equal
to the double meridian distance of the first course, plus its de-
parture, plus the departure of the second course.
III. The double meridian distance of the third course is equal
to the double meridian distance of the second, plus its departure,
plus the departure of the third course.
IV. ^nd, the double meridian distance of any course is equal
to the double meridian distance of the preceding course, plus its
departure, plus the departure of the course itself
Remark. It should be recollected that plus is here used
in its algebraic sense, and that when double the meridian
distance of a course and the departure which is to be added
to it, are of different names, that is, one east and the other
west, they will have contrary algebraic signs ; hence, their
algebraic sum will be expressed by their difference, with the
sign of the greater prefixed to it.
WITH THE COMPASS.
103
Demonstration of the Rule.
Let the figure JIB CD, which we i^
have aheady surveyed with the com-
pass, be resumed. By inspecting
the field notes, it will be seen that
B, or station 2, is the most westerly
station. Through this point let the
assumed meridian NS be supposed
to pass. Then, B will be the princi-
pal station, and BC the first course.
By what has been already said, every
departure towards the east is to be
considered as plus, and every departure towards the west, as
minus.
Now, since p. A:, d and a, are the middle points of the
courses BC^ CD, DA and AB, we have, by similar triangles,
2 qp=2 sx=sC =ihe first departure.
2 Cr=2 hk = Cy = ih.e second departure.
2fg=2 gA=Af=i[ie third departure.
2 At=2 ab= Ac =ihe fourth departure.
We also have,
2 qp=sC=douh. mer. dis. of BC,
2 qp+2 xC-{-2 Cr = 2 A:n=doub. mer. dis. of CD. '
2 kn-{-2 kh-2 gf=2 c?e=doub. mer. dis. of DA.
2 de — 2 gA — 2 At =2 a6 = doub. mer. dis. of AB.
The departure of the courses BC, CD, are east, and there-
fore positive ; while the departures of the courses DA, AB,
are west, and consequently negative.
Since the course of reasoning just pursued is applicable to
all figures, we may regard the rule as demonstrated for every
case which can occur.
Remark. The double meridian distance of the last course
should be equal to the departure of that course. A verifi-
cation of the work is, therefore, obtained by comparing this
double meridian distance with the departure of the course.
142. To apply the above rule to the particular example
already considered, rule a new table, as below, in which are
entered the balanced northings and southings, and the bal-
anced eastings and westings.
104
ELEMENTS OF SURVEYING.
In this table there is but a single column for the diflerence
of latitude, and a single column for the departures. The
-|- sign shows when the difference of latitude is north, and
the — sign, when it is south. The -j- sign also shows when
the departure is east, and the — sign, when it is west.

We see, from inspecting the notes, that 2 is the most
westerly, and 4 the most easterly station. Either of them
may, therefore, be taken for the principal station. Let us
assume 2 for the principal station, and distinguish it by a
star, thus *.
Having done so, we enter the departure 8.21 in the column
of double meridian distances, which gives the double meridian
distance of the first course. The double meridian distances
of the other courses are calculated according to the rule ; and
as the last, opposite to station 1, is equal to the departure of
the course, the work is known to be right.
Of the Area.
143. Having calculated the double meridian distance of
each course, the next and last operation for finding the content
of the ground, is explained in the following
RULE.
I. Multiply the double meridian distance of each course by
its northing or southing, observing that like signs in the multi-
plicand and multiplier give plus in the product, and that unlike
signs give minus in the product.
II. Place all the products which have a plus sign in one
column, and all the products which have a minus sign in another.
III. *Bdd up each of the columns separately and take their
difference : this difference will be double the area of the land.

It is now evident, that cB multiplied by 2ba = cA, wil
give double the area of the triangle cAB. But cB and ba
are both plus ; hence, the product will be plus, and must be
put in the column of plus areas. Double the area of the
triangle BsC, is equal to Bs multiplied by 2qpf which pro-
duct is also plus.
The area of the trapezoid msCD is equal to yD=ms multi-
plied by nh (Geom. Bk. IV, Prop. VII) ; hence, double the
area is equal to yD into 2nh. But since yD is minus, and
2nh plus, it follows that the product will be negative ; hence,
it must be placed in the column of negative areas.
Double the area of the trapezoid cJlDm, is equal to Df=mc
multiplied by 2de : but, since Df is negative and 2de posi-
tive, the product will be negative.
It is now evident that the difference between the two
columns is equal to twice the content of the figure ABCD *

Observing in the field notes that station 2 is the most
westerly point of the land, we assume the meridian which
passes through this point, as the one from which the me-
ridian distances are calculated. We mark the principal sta-
tion with a star.
Opposite station 2, we enter, in the column of double me-
ridian distances, headed D. M. D., the departure of the course
from 2 to 3, which is the double meridian distance of that
course, and plus. To this we add the departure of the
course, and also the departure of the next course : their sum
is the double meridian distance of the course from 3 to 4.
To the last sum add the departure opposite station 3, and
the minus departure opposite station 4 : their algebraic sum is
the double meridian distance from 4 to 1.
To the last sum add tne last departure, which is minus,
also the next departure which is likewise minus : this will
give the double meridian distance of the course from l to 2,
which is also equal to its departure.
Then forming the products, adding them together, taking
their difTerence, and dividing it by 2, according to the rule, we
obtain the content of the ground.

144. It only remains to make a
plot of the ground.
For this purpose, draw any line,
as NS, to represent the meridian
passing through the principal sta-
tion, on which take any point, as
Bt to represent that station.
FIRST METHOD OF PLOTTING.
Having fixed upon the scale on which the plot is to be
made, lay off from B on the meridian, a distance Bs equal to
the difference of latitude of the first course, and at s erect a
perpendicular to the meridian, and make it equal to the de-
parture of the first course : then draw BC, which will be the
first course.
Through C draw a meridian, and make Cf equal to the
difference of latitude of the second course, and through /
draw a perpendicular /D, and make it equal to the depar-
ture of the second course : draw CD, and it will be the
second course.
Lay down, in the same manner, the courses DA and AB,
and the entire plot will be completed.
SECOND METHOD OF PLOTTING.
The work may be plotted in another manner, thus. At
the principal station B, lay off an angle equal to the bearing
from B to C, which will give the direction of BC. Then,
firom the scale of equal parts, make BC equal to the first
course : this will give the station C.
Through C draw a meridian, and lay off an angle equal to
the bearing from C to D, and then lay off the course CD.
Do the same for the bearing at D and the course DA; also,
for the bearing at A and the course AB, and a complete plot
of the ground will thus be obtained. If the work is all right,
the last line AB will exactly close the figure. This plot is
made on a scale of 40 chains to an inch.

PROBLEM.
To determine the content and boundary of a piece of land, hi/
means of offsets from the principal lines.
145. An offset is a line drawn perpendicular to a course,
and may lie either on the right or left of it.
146. Let ABODE be a piece of
ground to be surveyed. Let us sup-
pose it to be bounded on the west
and north by a fence and road, and
on the east and south by a creek or
river.
Place stations at the principal
points, as A, B, C, D and E, Take,
with the compass, the bearings from
A to J5, from B to C, from C to D,
from D to E, and from E to A ; and
measure the distances AB, BC, CD,
DE, and EA.
At convenient points of the course AB, as a, c and /, make
the offsets ab, cd, fg. Then, having measured these lines,
as also the distances Aa, ac, cf and fB, enough will be
known to determine the area which lies without the station

line JIB. The points 6, d, and g^ of the fence which runs
from A to B, are also determined.
Erect, in a similar manner, offsets to the other courses,
and determine the areas which lie without the station lines.
Tliese several areas being added to the area within the sta-
tion lines, will give the entire area of the ground.
If the offsets fall within the station lines, the corresponding
area must be subtracted from the area which is bounded by
the station lines.
PROBLEM.
To determine the bearing and distance from one point to another^
when the points are so situated that one cannot be seen from the
other.
147. Let AB be a meridian, and
*^ and C the two points. From
either of them, as A, measure a
course .^2, of a convenient length
in the direction towards C, and take
the bearing with the compass. At
2, take the bearing of a second
course, and measure the distance
to 3. At 3, take a third bearing and
measure to 4. At 4, take the bear-
ing to C, and measure the distance
from 4 to C.
Then, the difference between the
sum of the northings and the sum of the southings will be
represented by AB, and the difference between the sum of
the eastings and the sum of the westings by BC. The base
AB, and the perpendicular BC of the right-angled triangle
ABC, are then known. The angle at the base, BAC, is the
bearing from A to C; or the equal alternate angle at C is
the bearing from C to A, and the hypothenuse AC is the
distance.
Having measured the bearings and courses on the field,
form a table, and find the base and perpendicular of the right-
angled triangle, in numbers.

equal to the sum of the northings,

cles which prevent the measuring of a course, or when the

always be supplied by calculation. It is far better, however,
if possible, to take all the notes on the field. For, when any
of them are supplied by calculation, there are no test by
which the accuracy of the work can be ascertained, and all
the errors of the notes affect also the parts which are supplied.

149. Let NS be a meridian

Let ^B, AC, AD and AH be

c^C is N 260 W ^ When the meridional letters arc

will be the angle between the courses.
AB is N 46* E ^ When the meridional letters are
w3C is N 26° W > alike, and those of departure unhke,
CAB = 12^ ^ the sum of the bearings will be the
angle between the courses.
When the meridional letters are
.^C is N 26° W J unhke, and those of departure alike,
AD is S 66° W \ the angle between the courses will be
CAD— 180'^ — Q2° = 88° 5 equal to 180° minus the sum of the
bearings.
When the meridional letters are
.y^C is N 26° W ^ unlike, and those of departure also
AF is S 66° E > unlike, the angle between the courses
Cj2F=180° — 40°=140o ^ will be equal to the difference of the
bearings taken from 180°.
Remark. The above rules are determined, under the sup-
position that the two courses are both run from the angular
point. Hence, if it be required to apply the rules to two
courses run in the ordinary way, as we go around the field,
the bearing of one of them must be reversed before the calcu-
lation for the angle is made.

PROBLEM.
To run a line from a given point in the boundary of a piece
of land, so as to cut off on either side of it a given portion
of the field.
150. Make a complete survey of the field, by the rules
already given. Let us take, as an example, the field whose
area is computed at page 106. That field contains I04w3
ijR 16P, and the following is a plot of it.
N
Let it now be required to run a line from station A, jq
such a manner as to cut off on the left any part of the field ;
say,
26^ 2R ZIP.
It is seen, by examining the field, that the division line
will probably terminate on the course CD. Therefore, draw
a line from A to C, which we will call the first closing line.
The bearings and lengths of the courses JIB, BC, are
always known ; and in the present example are found in the
WITH THE COMPASS. 119
table on page 106 : hence, the bearing and distance from C
to ./?, can be calculated by the last problem : they are in this
example,
Bear. S 9° 28' E : Course 22.8 ch.
Having calculated the bearing and length of the closing
line, find, by the general method, the area which it cuts off:
that area, in the present case, is
13^ 3R SP.
It is now evident that the division line must fall on the
right of the closing line AC, and must cut off an area ACH,
equal to the difference between that already cut off, and the
given area : that is, an area equal
26 A 2R 31 P given area.
13^5 SR 3P area already cut off.
to . . . 12.^2 3R 28P.
Since the bearing of the next course CD, and the bearing
of the closing line AC are known, the angle ACD which
they form with each other, can be calculated, and is in this
example 80° 32°. Hence, knowing the hypothenuse AC, and
the angle ACG at the base, the length AG of the perpen-
dicular let fall on the course CD, can be found, and is
22.49 chains.
Since the area of a triangle is equal to its base multiplied
by half its altitude, it follows, that the base is equal to the
area divided by half the altitude. Therefore, if the area
12 A 3R 28P
be reduced to square chains, and divided by 11.24^ chains,
which is half the perpendicular AG, the quotient, which is
1 1.58 chains, will be the base CH. Hence, if we lay off from
C, on CD, a distance CH, equal to 11.5 chains, and then run
the line AH, it will cut off from the land the required area.
Remark I. If the part cut off by the first closing line,
should exceed the given area, the division line will fall on
the left of AC.
Remark II. If the difference between the given area and
the first area cut off, divided by half the perpendicular AG,
gives a quotient larger than the course CD ; then, draw a
120 ELEMENTS OP SURVEYING.
line from ^5 to D, and consider it as the first closing line, and
let fall a perpendicular on DE.
Remark III. When the point from which the division
line is to be drawn, falls between the extremities of a course,
dividing the course into two parts, consider one of the parts
as an entire course, and the otlier as forming a new course,
having the same bearing. Tlie manner of making the cal-
culation will then be the same as before.
Method of determining the area of a Survey by means of the
Table of J^atural Sines and Cosines.
If, in a circle of which the radius is 1, we calculate the
sine and cosine for every minute of the quadrant, they form
what is called a Table of Natural Sines and Cosines. The
natural sine is the perpendicular, and the natural cosine the
base of a right angled triangle of which the hypothenuse,
or radius of the circle, is 1.
Since either leg of a right angled triangle is less than the
hypothenuse, it follows that the natural sine or cosine of every
arc of the quadrant is less than 1. These sines and cosines
are expressed in decimals of the radius 1, and although the
decimal point is not written in the table, yet it must always
be prefixed to the number before using it.
Thus in page 67, the sine of 5° 30' is .09585.
The cosine of 5° 30' „ .99540.
Sine of 40° 25' (page 71) „ .64834.
Cosine of 40° 25' „ .76135.
When the angle exceeds 45°, the degrees are found at the
bottom of the page, and the minutes are counted upwards in
the right hand column of the page, as in the table of loga-
rithmic sines.
Thus, sine of 84° 20' (page 64)

If the Surveying Compass has a vernier which enables you
to read the bearings to smaller parts of a degree than 15',
greater accuracy may be attained by using the table of
natural sines, instead of the Traverse Table, for computing
the area.
We shall now show the method of calculating the latitude
and departure of any course, from the table of natural sines.
Let JID, for example be any course,
DAE the bearing, and AC=l the
radius of the table of natural sines.
Having formed the right angled ^ B
triangles ACB, JlDE, we have DAE = hesLnng,
AE=di{. of latitude and jEZ) = departure,
.^5 = cosine of bearing and ^C= sine of bearing.
From similar triangles, we have,
AB \\ AD : AE ; that is,
AC
1 : cosine of bear. : : course : dif. of lat. ; hence,
dif. of latitude = course X cosine of bearing ; that is ;
The difference of latitude is equal to the length of the course
multiplied by the cosine of the bearing.
Again,
AC : CB :: AD : DE; that is,
1 : sine of bearing : : course : departure ; hence,
departure = course x sine of bearing, that is.
The departure is equal to the length of the course multiplied by
the sine of the bearing.

0.01720 Error in Easting.
0.00860 Half Error.
Instead of balancing by the method explained m Art. 138,
we divide each error by two. Now if we subtract half the
error in southing from the column of northings and at the
same time add it to the column of southings, these two
columns will exactly balance. In like manner, if we subtract
half the error in easting from the column of westings and at
the same time add it to the column of eastings, these cohimns
will also balance.
The errors should be distributed in proportion to the lengths
of the courses, but this may be done with sufficient accuracy
without making the proportions. If any of the courses have
been run over rough ground, the probability is that the errors
belong to these courses and they should be distributed among
them.
In this example we separate the half error in southing into
the three parts .40700, .21302 and .04674, and subtract them
respectively from the northings of courses 2, 1 and 3, and then
place the northings in the balanced columns. For the south-
ings, we separate the error into the four parts .40772, .2 0031,
.03121, and .02752, and add them respectively to the south-
ings of the courses 4, 5, 8 and 7. We then enter the southings
in the balanced columns. As the error in easting is so small
we add half of it to the easting of course 3, and subtract half
from the westing of course 7.

Having entered the balanced latitudes and departures we
seek for the most easterly or westerly station. We see at
once that station 2 is the most westerly.
Assuming this for the principal station (see Art. 14 1), the
double meridian distances will all be east, and consequently
will be plus.
We then enter the departure of course 2 in the column of
double meridian distances, and then calculate the double
meridian distance of each course, according to the rule given
in Art. 141.
Having done this we multiply each departure by the double
meridian distance of its course and place the product in the
column of plus or minus areas, according as the signs of the
factors are like or unlike. We enter but five decimal places
in the columns of areas. This will give the result with suffi-
cient accuracy. We then add up the columns of area, take
the difference of the two sums, divide it by two and reduce
the quotient to acres, roods and perches.
We thus find the area to be 1298 acres, 1 rood and 6 perches.

ELEMENTS OF SURVEYING.
Method of Surveying the Public Lands.
151. Soon after the organization of the present government,
several of the states ceded to the United States large tracts of
wild land, and these together with the lands since acquired
by treaty and purchase, constitute what is called the public
lands or public domain. Previous to the year 1802 these
lands were parcelled out without reference to any general
plan, in consequence of which the titles often conflicted with
each other, and in many cases, several grants covered the
same premises.
In the year 1802, the following method of surveying the
public lands, was adopted by Colonel Jared Mansfield, then
surveyor-general of the North-Western Territory.
152. The country to be surveyed is first divided by par-
allel meridians, six miles distant .from each other ; and then
again, by a system of east and west lines, also six miles from
each other. The whole country is thus divided into equal
squares, which are called townships. Hence, each township
is a square, six miles on a side, and contains 36 square miles.
The townships which lie along the same meridian, are
called a range, and are numbered, to distinguish them from
each other.
Each township is divided into equal squares, by meridians
one mile apart, and by east and west lines at the same dis-
tance from each other. Hence, each township is divided into
36 square miles, each one of which is called a section. The
sections of a township are numbered from 1 to 36, and each
contains 640 acres.
Tlie diagram exhibits the 36 sections of a township.
i ( 1 i
WITH THE COMPASS. 127
To describe a section accurately, we saj?^, section number
5, in township number 4, in range 3d, west of a known me-
ridian, the one, for example, drawn through the mouth of the
Great Miami river. This description fixes precisely the place
of the section. Go to the 3d range of townships, west of the
known meridian, find township number 4 in this range, and
lastly, section number 5 of that township. Tiie corners of
the sections should be marked by permanent corner-posts, or
by lines blazed on trees.
The sections are divided into half sections, quarter sections,
and even into eighths of sections. The following table shows
the content of a township, and its subdivisions.
1 township = 36 sections = 23040 acres.
1 section = 6 40 acres.
I section = 320 acres.
^ section = 160 acres.
■1 section = 80 acres.
The principal meridians, and the principal east and west
hues, have been established by astronomical observation, and
the lines of subdivision run with the compass..
VARIATION OF THE NEEDLE.
153. The line indicated by the magnetic needle, when
allowed to move freely about the point of support, and settle
to a state of rest, has been called the magnetic meridian.
This, in general, is a different line from the true meridian,
which always passes through the poles of the earth, when
sufliciently produced in both directions.
154. The angle which the magnetic meridian makes with
the true meridian, at any place on the surface of the earth, is
called the variation of the needle at that place, and is east or
west, according as the north end of the needle lies on the
east or west side of the true meridian.
155. The variation is diflerent at different places, and even
at the same place it does not remain constant for any length
of time. The variation is ascertained by comparing the mag-
netic, with the true meridian.
156. The best practical method of determining the true
meridian of a place, is by observing the north star. If this
star were precisely at the point in which the axis of the earth,
128
ELEMENTS OP SURVEYING.
produced, pierces the heavens, then, the interh^eclion of the
vertical plane passing through it and the place, with the sur-
face of the earth, would be the true meridian. But, the star
being at a distance from the pole, equal to 1° 34' nearly, it
performs a revolution about the pole in a circle, the polar dis-
tance of which is 1° 34' : the time of revolution is 2 3 h. and
56 min.
To the eye of an observer, this star is continually in motion,
and is due north but twice in 23 h. 56 min. ; and is then said
to be on the meridian. Now, when it departs from the me«
ridian, it apparently moves east or west, for 5 h. and 59 min.,
and then returns to the meridian again. When at its greatest
distance from the meridian, east or west, it is said to be at its
greatest eastern or western elongation.
The following tables show the times of its greatest eastern
and western elongations.

The eastern elongations are put down from the first of
April to the first of October ; and the western, from the first
of October to the first of April ; the time is computed from

ring- in the evening, before it is dark, or after daylight in the
morning. In such case, if it be necessary to determine the
meridian at that particular season of the year, let 5 h. and
59 min. be added to, or subtracted from, the time of greatest
eastern or western elongation, and the observation be made at
night, when the star is on the meridian.
The following table exhibits the angle which the meridian
plane makes with the vertical plane passing through the pole-
star, when at its greatest eastern or western elongation : such
angle is called the azimuth. The mean angle only is put
down, being calculated for the first of July of each year

The use of the above tables, in finding the true meridian,
will soon appear.
To find the true meridian with the theodolite.
157. Take a board, of about one foot, square, paste white
paper upon it, and perforate it through the centre ; the diam-
eter of the hole being somewhat larger than the diameter of
tlie telescope of the theodolite. Let this board be so fixed
130 ELEMENTS OF SURVEYING.
to a vertical staff, as to slide up and down freely : aiivl lot a
small piece of board, about three inches square, be nailed to
the lower edge of it, for the purpose of holding a candle.
About twenty-five minutes before the time of the great esf
eastern or western elongation of the pole-star, as shown b\
the tables of elongations, let the theodolite be placed at a con*
venient point and levelled. Let the board be placed about
one foot in front of the theodolite, a lamp or candle placed on
the shelf at its lower edge ; and let the board be slipped up or
down, until the pole-star can be seen through the hole. The
light reflected from the paper will show the cross hairs in the
telescope of the theodolite.
Then, let the vertical spider's line be brought exactly upon
the pole-star, and, if it is an eastern elongation that is to be
observed, and the star has not yet reached the most easterly
point, it will move from the line towards the east, and the
reverse when the elongation is west.
At the time the star attains its greatest elongation, it will
appear to coincide with the vertical spider's line for some time,
and then leave it, in the direction contrary to its fovmer
motion.
As the star moves towards the point of greatest elongation,
the telescope must be continually directed to it, by means of
the tangent-screw of the vernier plate ; and when the star
has attained its greatest elongation, great care should be
taken that the instrument be not afterwards moved.
Now, if it be not convenient to leave the instrument in its
place until daylight, let a staff, with a candle or small lamp
upon its upper extremity, be arranged at thirty or forty yards
from the theodolite, and in the same vertical plane with the
axis of the telescope. This is easily effected, by revolving
the vertical limb about its horizontal axis without moving
the vernier plate, and aligning the staff to coincide with the
vertical hair. Then mark the point directly under the theodo-
lite ; the line passing through this point and the staff, makes
an angle with the true meridian equal to the azimuth of the
pole-star.
From the table of azimuths, take the azimuth correspond-
ing to the year and nearest latitude. If the observed elonga-
tion were east, the true meridian lies on the west of the lirio
which has been found, and makes with it an angle equal to
VARIATION OF THE NEEDLE. 131
die azimuth. If the elongation were west, the true meridian
lies on the east of the line : and, in either case, laying off the
azimuth angle with the theodolite, gives the true meridian.
To find the true meridian with the compass.
158. 1. Drive two posts firmly into the ground, in a line
nearly east and west ; the uppermost ends, Avhen driven
firml}', heing about three feet above the surface, and the posts
about four feet apart : then lay a plank, or piece of timber
three or four inches in width, and smooth on the upper side,
upon the posts, and let it be pinned or nailed, to hold it firmly.
2. Prepare a piece of board four or five inches square, and
smooth on the under side. Let one of the compass-sights be
placed at right angles to the upper surface of the board, and
let a nail be driven through the board, so that it can be tacked
to the timber resting on the posts.
3. At about twelve feet from the stakes, and in the direc-
tion of the pole-star, let a plumb be suspended from the top
of an inclined stake or pole. The top of the pole should be
of such a height that the pole-star will appear about six
inches below it ; and the plumb should be swung in a vessel
of water to prevent it from vibrating.
This being done, about twenty minutes before the time of
elongation, place the board, to which the compass-sight is
fastened, on the horizontal plank, and slide it east or west,
until the aperture of the compass-sight, the plumb line, and
the star, are brought into the same range. Then if the star
depart from the plumb-line, move the compass-sight, east
or west, along the timber, as the case may be, until the star
shall attain its greatest elongation, when it will continue
behind the plumb-line for several minutes ; and will then
recede from it in the direction contrary to its motion before it
became stationary. Let the compass-sight be now fastened
to the horizontal plank. During this observation it will be
necessary to have the plumb-line lighted : this may be done
by an assistant holding a candle near it.
Let now a staff, with a candle or lamp upon it, be placed
at a distance of thirty or forty yards from the plumb-line, and
in the same direction with it and the compass-sight. The
line so determined, makes, with the true meridian, an ojsi^le
132 ELEMENTS OP SURVEYING.
equal to the azimuth of the pole-star; and, from this line,
the variation of the needle is readily determined, even witliout
tracing the true meridian on the ground.
Place the compass upon this line, turn the sights in the
direction of it, and note the angle shown by the needle.
Now, if the elongation, at the time of observation, were west,
and the north end of the needle on the west side of the line,
the azimuth, plus the angle shown by the needle, is tlie true
variation. But should the north end of the needle be found
on the east side of the line, the elongation being west, the
difference between the azimuth and the angle would show the
variation : and the reverse when the elongation is east.

Remark I. The variation at West Point, in September,
1835, was 6° 32' west.
Remark II. The variation of the needle should always
be noted on every survey made Avith the compass, and then
if the land be surveyed at a future time, the old lines can
always be re-run.
159. It has been found by observation, that heat and cold
sensibly affect the magnetic needle, and that the same needle
will, at the same place, indicate different lines at different
hours of the day.
If the magnetic meridian be observed early in the morning,
and again at different hours of the day, it will be found that
the needle will continue to recede from the meridian as the
day advances, until about the time of the highest tempera-

the same line as in the morning. This change is called the
diurnal variation, and varies, during the summer season, from
one-fourth to one-fifth of a degree.
OF THE PLAIN-TABLE.
160. PL 3, Fig. 1. The plain-table consists of two parts;
a rectangular board CDBA, and a tripod EHG, to which it
is firmly secured.
Directly under the rectangular board are four milled screws
which pass through sockets inserted in a horizontal brass
plate : these screws are worked against a second horizontal
plate, for the purpose of levelling the table ; the table having
a ball and socket motion, similar to the limb of the theodolite.
For the purpose of levelling the table, a small detached
spirit-level is used. This level being placed over the centre,
and also over two of the levelling screws, the screws are turned
contrary ways until the level is horizontal ; after which, it is
placed over the other two screws, and made horizontal in the
same manner.
Between the upper horizontal plate and the table, there is
a clamp-screw, similar to the clamp-screw of the theodolite,
which being loosened, the table can be turned freely about
its axis. There is, also, a small tangent-screw, by which the
smaller motions of the table are regulated, after the clamp-
screw is made fast. Neither of these screws can be seen in
the figure.
The upper side of the table is bordered by four brass plates,
about one inch in width, and the centre of the table is marked
by a small pin, F. About this centre, and tangent to the
sides of the table, conceive a circle to be described. Suppose
the circumference of the circle to be divided into degrees and
parts of a degree, and radii to be drawn through the centre
and the points of division. The points in which these radii
intersect the outer edge of the brass border, are marked by
lines on the brass plates, and the degrees are numbered in the
direction from left to right, from the point L to the point /,
180°, and from the point / to the point L, 180°. In some
plain-tables, however, they are numbered from 0 to 360".
There are, generally, diagonal scales of equal parts cut on
134 ELEMENTS OF SURVEYING.
the plates DLC and AIB^ the use of which will be explained
hereafter.
Near the two other edges of the table, two small grooves
are made, into which the plates of brass DB and CJi are
fitted, and these plates are drawn to their places by means of
milled screws which pass through the table from the under
side, and screw firmly into the plates. The heads of two of
the screws, Q and S, are seen in the figure, as also one of the
plates and its two screws in Fig. 3. The object of these
plates is to confine a sheet of paper on the table. By loosen-
ing the screws, and pressing them upwards, the plates are
raised above the surface of the table ; the edges of the paper
can then be placed under them : then, by turning the screws
back again, the plates are drawn down and the paper held
tightly. Fig. 1 represents the table with the paper partly put
upon it : one edge of the paper has been placed under the
plate DB, and the screws >S and Q, tightened. The paper,
before being put on, should be moistened, in order to expand
it; and then, after it has been dried, it will fit closely to the
table.
A ruler, JIB (Fig. 2), with open vertical sights, is used
with the plain-table. This ruler has a fiducial edge, which
is in the same vertical plane with the hairs of the sights.
A ruler with a telescope, and a vertical limb, similar to the
vertical limb of the theodolite, is sometimes used with the
plain-table. A compass, also, is often attached to the table,
to show the bearings of the lines.
The plain-table is used for two distinct objects.
1st. For the measurement of horizontal angles.
2dly. For the determination of the shorter lines of a sur-
vey, both in extent and position.
To measure a horizontal angle.
161. Place, by means of a plumb, the centre of the table
directly over the angular point : then level the table ; after
which, place the fiducial edge of the ruler against the small
pin at the centre : direct the sights to one of the objects, and
note the degrees on the brass plate ; then turn the ruler and
sights to the other object, and note the degrees as before.
If the ruler has not passed over the 0 point, the difference of
the readings is the angle sought ; but, if it has, the larger

taken from 180*, and the remainder added to the smaller,
gives the required angle.
Of the determination of lines in extent and position.
162. Having placed a paper on the table, examine the ob-
jects and lines which are to be determined, and measure a
base line in such a direction, if possible, that all the objects
can be seen from its extremities. Then place the plain-table
with its centre, nearly, though not accurately, over one ex-
tremity of the base ; make it truly horizontal, and turn it
until the larger part of the paper lies on the same side of the
base with the objects.
Then, tighten the clamp-screw, and mark with a pin the
point of the paper directly over the station, which point is de-
termined most accurately by suspending a plumb from the
lower side of the table. Press the pin /irmly on this point,
bring the fiducial edge of the ruler against it, and sight to the
other extremity of the base line, and mark with the pin or
pencil, the direction of the line on the paper. Sight in like
manner to every other object, and draw on the paper the cor-
responding lines, numbering them from the base line, 1, 2, 3,
4, &c.
Then, with a pair of dividers, take from the scale a certain
number of equal parts to represent the base, and lay off the
distance on the base line from the place of the pin. Take
up the table, carry it to the other extremity of the base, and
place the point of the paper corresponding to that extremity,
directly over it. Place the fiducial edge of the ruler on the
base line, and turn the table, by means of the tangent-screw,
until the sights are directed to the first station. If, however,
in bringing the table to this position, the corresponding point
of the paper has been moved from over the extremity of the
base line, move the legs of the tripod until it is brought back
to its place. Let the table be then levelled, after which,
place the ruler again on the base line, and bring the table to
its proper position by the tangent-screw, and continue the ad-
justment until the extremity of the base line on the paper is
directly over the station, and in the same vertical plane with
the base line on the ground. Then direct the sights to all
the objects sighted to from the other station, and mark the
lines 1, 2, 3, 4, &c. from the base line, as before. The inter-

sections of the corresponding lines 1,1, 2,2, 3,3, 4,4, &c*,
determine, on the paper, the positions of the several objects;
and a reference of these lines to the scale of equal parts,
determines the true distances.
1 63. Let it be required, for ex-
ample, to determine, by means
of the plain-table, the relative
position of several houses.
Measure the base line JiB,
which we will suppose equal
to 300 yards. Place the plain-
table at A, and sight to the
corners of the houses, and mark the lines 1, 2, 3, 4, &c. Then
remove the table to B, and sight to the same corners as
before, and draw the lines as in the figure. The points at
which they intersect the corresponding lines before drawn,
determine the corners of the houses. The front lines of the
houses may then be drawn on the paper. Draw lines at riglil
angles to the front lines, and on them lay off the depths of
the houses, with the same scale as that used for the base line.
To find the length of any line drawn on the paper, as the
line 1, drawn through A, for example, place the dividers at
A and extend them to the other extremity of the line, and
then apply the line to the scale. The length of the line 1 is
equal to 198 yards.

termine from the base line CD,
the positions of the points B, F,
E, and H.
Of changing the Paper.
165. When one paper is filled, and there is yet more work
to be done, let the paper be removed, and a second paper put
on the table ; after which, the table may be used as before.
Now, in order that the two papers may be put together and
form one entire plan, it is necessary that two points deter-
mined on the first paper, be also determined on the second ;
and then, by placing the lines joining these points upon each
other, all the lines on the two papers will have the same

relative position as the corresponding lines on the ground ;
and the same for as many papers as it may be necessary to
use. If -different scales are used, the corresponding points
will not join, and then the work must be reduced to the same
scale, before the papers can be put together.
In the first example, the position of the point F was deter-
mined, in order to unite the first paper with the second.
In the second example, we sighted from C and D, the
extremities of the base line, to the points B and F; we thus
determined the hue BF on the second paper. Placing the
line BF of the one paper on BF of the other, we have the
following plan.
In this plan, all the points and lines are accurately laid
down. Any number of papers may be joined in the same
manner.
The plain-table is used to great advantage when only a
plot of the ground is wanted. It ought not to be used for
the determination of long lines, nor can it be relied on in
determining extended areas.
CHAPTER V.
Of Levelling.
166. If all the points of the earth's surface were equidistant
from the centre, it would be perfectly even, and present to
the eye an unbroken level.
Intersected, however, as it is, by valleys and ridges of
mountains, it becomes an important problem to ascertain the
difference between the distances of given points from the
centre of the earth ; such difference is called the difference
138 ELEMENTS OF SURVEYING.
of level ; and a line, all the points of which are equally dis-
tant from the centre, is called the line of true level*
167. One point is said to be above another, when it is
farther from the centre of the earth ; and below it, when it is
nearer.
168. Let C (PL 4, Fig. 1), represent the centre of the
earth. A a point of its surface, and JIEF the line of true
level. If, at the point Jl, a tangent line JlBD be drawn to
the surface, such line is called the line of apparent level.
169. Now, if an instrument were placed at Ay and brought
into a horizontal position so as to indicate a horizontal line,
this line would be tangent to the earth at A, and would be
the line ABD of apparent level.
170. When, therefore, we have ascertained the direction of
a tangent, or horizontal line, we have found the line of appa-
rent level only ; the line of true level is yet to be determined.
If at the points E and jP, vertical staves be placed, the
line of apparent level passing through A will cut them at
B and D, while the line of true level cuts them at E and F.
Therefore, BE and DF are, respectively, the differences be-
tween the apparent levels of the points E and F, as deter-
mined by the horizontal line passing through A^ and the true
levels of those points.
But AB' = BE {BE+^EC), and AD^=DF (DF+sFC)
(Geom. Bk. IV, Prop. XXX). In the common operations of
levelling, the arcs AE, AF, are small ; and since the differ-
ence between small arcs and their tangents is very incon-
siderable, the arcs AE, AF may be substituted for the tan-
gents AB, AD. And since the external parts of the secants
BE and DF are very small in comparison with the diameter
of the earth, they may be neglected without sensible error :
the expressions above will then become,
AE'=BEx2EC, and AF^=DFx2FC,
J.J. AE^ . j.j^ AF^
or, BE= ; and DF= ;
2EC 2FC
and since the diameter of the earth is constant, BE and DF
are proportional to AE^ and AF^.
* The spheroidal form of the earth is not considered, as it affects the results
too inconsiderably to be regarded in the common operations of levelUng.
OF LEVELLING.
139
But BE and DF are respectively the differences between
the true levels of the points E and F, and their apparent
levels, as determined from the point A : hence, the difference
between the apparent and true level of any point, is equal to
the square of the distance of that point from the place where the
apparent level was made, divided by the diameter of the earth;
or, the diameter being constant, the rise of the apparent above
the true level, is proportional to the square of the distance.
171. The mean diameter of the earth being about 7919
miles, if AE be taken equal to 1 mile, then the excess
ft 7^2 1
BE=—T— becomes equal to = 8.001 inches.

140 ELEMENTS OF SURVEYING.
We cnnnot proceed farther in the discussion of the principles
of levelling, until we have described the instruments which
are to be used, and explained the particular objects which
they are to answer.
OF THE LEVEL.
172. The level is an instrument used to determine hori-
zontal lines, and the difference of level of any points on the
surface of the earth.
The part of the instrument shown in PI. 4, Fig. 2, rests on
a tripod to which it is permanently attached at Z. IIH is a
horizontal brass plate, through which four levelling screws
with milled heads are passed, and worked against a second
horizontal plate GG. Two of these screws, K and /, are
seen in the figure. *S is a clamp-screw, which, being loosened,
allows the upper part of the instrument to turn freely around
its axis. Q is a tangent-screw, by means of which the upper
part of the instrument is moved gently, after the clamp-screw
S has been made fast. EE is a horizontal bar, perpendicular
to which are the wyes, designated F's,that support the tele-
scope LB. This telescope is confined in the F's by the loops
r, r, which arc fastened by the pins p and p. The object-
glass J5, is adjustedxto its focus by the screw X ; the eye-
glass L slides out and hi freely. The screws /, /, Avork the
slide which carries the ^horizontal hair ; and two horizontal
screws, only one of which, «, is seen, work the slide that
carries the vertical hair. CD is an attached spirit level. The
screw JV elevates and depresses the F, nearest the eye-glass.
In some instruments this Y is elevated and depressed, by
means of two screws at M and R.
Before using the level, it must be adjusted. The adjustment
consists in bringing the different parts to their proper places.
The line of collimation is the axis of the telescope. With
this axis, the Hne drawn through the centre of the eye-glass,
and the intersection of the spider's lines, within the barrel of
the telescope, ought to coincide.
First adjustment.* To fix the intersection of the spider's
lines in the axis of the telescope.
Having screwed the tripod to the instrument, extend the

theodolite, that they would not be repeated, but that some may use the level without
wishing to study a more complicated instrument
OF LEVELLING. 141
legs, and place them firmly. Then loosen the clamp-sciew S,
and direct the telescope to a small, well-defined,, and distant
object. Then slide the eye-glass till the spider's lines are
seen distinctly ; after which, with the screw X, adjust the
object-glass to its proper focus, when the object and the
Fpider's lines will be distinctly seen. Note now the precise
point covered by the intersection of the spider's lines.
Having done this, revolve the telescope in the F's, half
round, when the attached level CD will come to the upper
side. See if, in this position, the horizontal hair appears
above or below the point, and in either case, loosen the one,
and tighten, the other, of the two screws which work the hori-
zontal hair, until it has been carried over half the space
between its last position and the observed point. Carry the
telescope back to its place ; direct again, by the screws at
JH and R, the intersection of the spider's lines to the point,
and repeat the operation, till the horizontal hair neither
ascends nor descends while the telescope is revolved. A
similar process will arrange the vertical hair, and the line
of collimation is then adjusted.
Second adjustment. To make the axis of the attached
level CD parallel to the line of collimation.
Turn the screw JV, or the screws M and R, until the bub-
ble of the level DC stands at the middle of the tube. Then
open the loops, and reverse the telescope. If the bubble still
stands at the middle of the tube, the axis of the level is hori-
zontal ; but if not, it is inclined, the bubble being at the ele-
vated end. In such case, raise the depressed, or depress the
elevated end, by means of the screw h, half the inclination ;
and then with the screw JV, bring the level to a horizontal
position. Reverse the telescope in the F's, and make the
same correction again ; and proceed thus, until the bubble
stands in the middle of the tube, in both positions of the tele-
scope ; the axis of the level is then horizontal.
Let the telescope be now revolved in the F's. If the bub-
ble continue in the middle of the tube, the axis of the level
is not only horizontal, but also parallel to the line of collima-
tion. If, however, the bubble recedes from the centre, the
axis of the level is inclined to the line of collimation, and
142 ELEMENTS OF SURVEYING.
must be made parallel to it, by means of two small screws,
which work horizontally ; one of these screws is seen at q.
By loosening one of them, and tightening the other, the level
is soon brought parallel to the line of collimation ; and then,
if the telescope be revolved in the F's, the bubble will con
tinuc at the middle point of the tube. It is, however, difficult
to make the first part of this adjustment, while the axis of
the level is considerably inclined to the line of collimation :
for, allowing the level to be truly horizontal in one position
of the telescope, after it is reversed, there will be but one cor-
responding position in which the bubble will stand at the
middle of the tube. This suggests the necessity of making
the first part of the adjustment with tolerable accuracy ; then,
having made the second with care, re-examine the first, and
proceed thus till the adjustment is completed.
Third adjustment. To make the level CD and the line of
collimation perpendicular to the axis of the instrument, or parallel
to the horizontal bar EE.
Loosen the clamp-screw S, and turn the bar EE, until the
level DC comes directly over two of the levelling screws. By
means of these screws, make the level CD truly horizontal.
Then, turn the level quite round ; if, during the revolution,
it continue horizontal, it must be at right angles to the axis
of the instrument about which it has been revolved. But if,
after the revolution, the level CD be not horizontal, rectify
half the error with the screw^s at M and jR, and half with the
levelling screws. Then place the bar EE over the other two
levelling screws, and make the same examinations and correc-
tions as before ; and proceed thus, until the level can be turned
entirely around without displacing the bubble at the centre.
When this can be done, it is obvious that the level DC and
the line of coUimation, are at right angles to the axis of the
instrument about which they revolve ; and since the axis is
carefully adjusted by the maker, at right angles to the bar
EE, it follows, that the line of collimation, the level DC,
and the bar EE, are parallel to each other.
The level is now adjusted. When used, however, it is
best to re-examine it every day or two, as the work will be
erroneous unless the adjustments are accurate.
OF LEVELLING. 143
Of Levelling Staves.
173. The levelling staves are used to determine the points
at which a given horizontal line intersects lines that are per-
pendicular to the surface of the earth, and to show the dis-
tance of such points of intersection from the ground.
They are thus constructed. AB (PL 4, Fig. 3) is a rec-
tangular piece of wood, in the middle of which is a groove
abed. Into this groove a slide Inst enters, and is moved freely
along the groove. At the upper end of the slide is a rectan-
gular board fhow, called a vane, six inches, in the direction
hi. The vane is divided into four equal parts, by the lines
fg, hi : the two rectangles //i, ig, are usually painted black,
and the other two, if, hg, white ; so that the lines /^ and hi
may be distinguished with great accuracy. The slide from
fg to In, is of the same length with the body of the staff
AB : hence, when the line fg coincides with be, the lower
end of the slide In, will coincide with ad. The pins p and q,
which work in grooves, and are largest at the ends p and q,
are pressed in to hold the slide in any position at which it
may be placed. The length of the staff is generally six feet,
and it is usually divided into eighths or tenths of an inch.
The slide is divided in the same way. The longer lines show
the feet, the shorter, the inches. The object to be attained by
these divisions, is, to ascertain the distance of the line fg from
the ground.
When the line fg is brought to the top of the staff, to
coincide with be, the lower line wio of the vane, coincides
with the line marked 6, on the left of the staff: which shows,
the staff standing upright, that the line fg is six feet above
the ground. From the line marked 6, to the lower end of
the staff, is, indeed, but 5 feet 9 inches ; but the line fg is
three inches above the line wio, so that fg is six feet from the
ground.
If, from the last position, the slide be run up until the line
wio coincides with the division marked 1, on the left of the
staff, the line fg will be six feet and one inch from the ground :
if, till it coincides with 6c, it will be six feet and three inches,
the inches being marked on the staff. If the slide be still run
up, until 7 on the slide coincides with be, the hne fg will be
seven feet from the ground. In the j&gure, the line fg is
144 ELEMENTS OF SURVEYING.
seven feet from the bottom of the staff. The count above 6
feet 3 inches is always made on the slide. The manner of
counting off, for the parts of an inch, is too plain to require
particular explanation.
Having run down the slide till the upper line h, of the
vane, coincides with be, place bB on the ground, and the
staff vertical. It is now plain, that the line fg is three inches
above the ground. These three inches are marked on the
right of the staff. If the slide be run up till the lower line h
coincides with 1, on the right of the staff, the line fg will be
one foot from the ground, and similarly, until six feet be
shown at the other end of the staff.
The feet are marked 1, 2, 3, &c., from the upper end, and
are reversed in the present position of the staff; but are up-
right when the staff is placed for use. In the last position of
the staff, the count is made at the lower line of the vane.
174. There is a method of testing the adjustments of the
level, which ought not to be neglected, since all the results de-
pend on the accuracy of the instrument. The method is this:
Tlie level being adjusted, place it at any convenient point,
as G (Fig. 4). At equal distances of about 100 yards, on
either side, and in the same line with the level, place the
levelling staves CE, BF. Make the level horizontal with
the levelling screws. Then, turn it towards either staff, as
BF, and run the vane up or down, as required, until the
intersection of the hairs strikes the centre : then make the
slide fast, and note carefully the neight of the vane. Turn
the level half round, and do the same in respect of the staff
CE. Let the telescope be now reversed in the F's. Sight
again to the staff BF, and note the exact height of the vane.
Let the telescope be now turned half round, and the same be
done for the staff CE. If the two heiglits last observed, are
equal to those first noted, each to each, the line of collimation
will be perpendicular to the axis of the instrument, and if the
bubble has, at the same time, preserved its place at the middle
point of the tube, the instrument is truly adjusted.
For, had the line of collimation been inclined to the axis
of the level, it would, in the first instance, have taken the
direction JlF or £d ; and when turned half round, it would
have taken the direction Ab or AE. The telescope being

145
reversed in the F's, and again directed to the staff BF, the
line of colhmation would take the direction Ad or AF, and
when turned to the staff CE, it would take the direction AE
or Ab : and the two distances BF, Bd, or Cb, CE, can only
be equal to each other when the line of coUimation falls on
the horizontal line gf.
175. Having described the instruments used in levelling,
we will explain the practical operations on the field.
When it is proposed to find the difference of level of anj
two objects, or stations, all levels made in the direction of the
station at which the work is begun, are, for the sake of dis-
tinction merely, called back-sights ; and levels taken in the
direction of the other station, fore-sights.
Before going on the field with the level, rule three columns,
as below, and head them, stations, back-sights, fore-sights.

176. To find the difference of level between any two points,
as A and G (PI. 4, Fig. 5).
The level being adjusted, place it at any point as B, as
nearly in the line joining A and G as may be convenient.
Place a levelling staff at A, and another at JV, a point lying
as near as may be in the direction of G. Make the level
horizontal, by means of the levelling screws ; turn the tele-
scope to the staff at A, and direct the person at the staff (o
slide up the vane until the horizontal line ab cuts its centre ;.
then note the distance Ab (equal to 10 feet in the present
example), and enter it in the column of back-sights, opposite
station l. Sight also to the staff at JV, and enter the distance

JVa, equal to 3 feet, in tlie column of fore-sights, opposite
station 1.
Take up 'the level, and place it at some other convenient
station, as C, and remove the staff at Jl, to M. Having
levelled the instrument, sight to the staff at JV, and enter the
distance J^d, 1 1 feet G inches, in the column of hack-sights,
opposite station 2 : sight also to the staff at M, and enter the
distance J\IJ^ equal 0, in the column of fore-sights, opposite
station 2.
Let the level he now removed to any other station, as Z>,
and the staff at A*, to some other point, as P. Let the dis-
tance J\Ig, equal to 6 feet 8 inches, be entered in the column
of hack-sights, opposite station 3, and the distance PJi, equal
to 4 feet 9 inches, in the column of fore-sights. Let the
instrument be now placed at E, and the distance Pm, equal
to 3 feet 9 inches, and Gn, equal to 8 feet 3 inches, be entered
opposite station 4, in their proper columns.
By adding up the columns, we find, that the sum of the
l)ack-sights is equal to 31 feet 11 inches, and the sum of the
fore-sights, IC feet; the difference, 15 feet and 11 inches, is
the difference of level of the points Jl and G.
DEMONSTRATION.
Let the back-sights he called plus, and the fore-sights,
minus.
Then, having let fall the perpendiculars J^F, Mil, PI, and
GL, on the horizontal line AL, it remains to be proved, that
the difference of level,
GL=^6 + JV^+Jl% + P>n-JVa-0-/iP-na
Now, Jlb-\-.m-J^a=M-\-ad = Fd;
Therefore, GL = Fd+Mg-{- Pm --liP-nG.
But Fd-\.Mg = IIg, and -f Pm-/iP= -/jm,
Therefore, GL = IIg-hm-nG = hI-{hm+nG) = GL.
As the same mj\y be shown in every example, we conclude
(hat, the difference between the sum of the fore-sights and the sum
of the back-sights is, in all cases, equal to the difference of level.
It is also evident that^ when the sum of the hack-sights
exceeds tlie sum of the fore-sights, the last station is more
elevated than the first ; and, conversely, if the sum of the

back-sights is less than the sum of tlie fore-sights, the second
station is lower than the first.
177. In tliis example, we have not regarded the difTerence
between the true and apparent level. If it be nece3sary to
ascertain the result with extreme accuracy, this difTerence must
be considered: and then, the horizontal distances between the
level, at each of its positions, and the staves, must be mea-
sured, and the apparent levels diminished by the differences
of level ; which differences can be found from the table.

In this example, the first column shows the stations ; the
second, the back-sights ; the third, the distances from the
level in each of its positions to the bflck staff; the fourth, the
fore-sights ; the fifth, the distances from the level to the
forward staff; the sixth and seventh, are the columns of back
and fore sights, corrected by the difference of level. The cor-
rections are thus made : — The difference of level in the table
corresponding to 20 chains, is 5 tenths of an inch, which be-
ing subtracted from 9 feet 8 inches, leaves 9 feet 7.5 inches for
the corrected back-sight ; this is entered opposite station 1 in
the sixth column. The difference of level corresponding, to
32 chains, is 1.280 inches, which being subtracted from the
apparent level, 1 foot 0 inches, leaves 1 foot 4.720 inciies for
the true fore-sight from station 1. The other corrections are
made in the same manner.
The sum of the back-sights being 44 feet 2.732 inr!ies,
and the sum of the fore-sights 9 feet 0.477 inches, it follows,
148 ELEMENTS OF SURVEYING.
that the difference, 34 feet 8.255 inches, is the true difference
of level.
178. In finding the true from the apparent level, we have
not regarded the effect caused by refraction on the apparent
elevation of objects, as well because the refraction is different
in different states of the atmosphere, as because the correc
tions are inconsiderable in themselves.
179. The small errors that would arise from regarding the
apparent as the true level, may be avoided by placing the
levelling staves at equal distances from the level. In such case,
it is plain, 1st, that equal corrections must be made in the
fore and back sights ; and, sdly, that when the fore and back
sights are diminished equally, the result, which is always the
difference of their sums, will not be affected.
This method should always be followed, if practicable, as it
avoids the trouble of making corrections for the difference of
true and apparent level.
The differences between the true and apparent level, being
very inconsiderable for short distances, if only ordinary accu-
racy be required, it will be unnecessary to make measure-
ments at all. Care, however, ought to be taken, in placing
the levelling staves, to have them as nearly at equal distances
from the level as can be determined by the eye ; and if the
distances are unequal, let the next distances also be made
unequal ; that is, if the back-sight was the longest in the first
case, let it be made proportionably shorter in the second, and
the reverse.
CHAPTER VL
Of the methods of showing the contour and accidents of ground.
180. Besides the surveys that are made to determine the
area of land and the relative positions of objects, it is fre-
quently necessary to make minute and careful examinations
for the purpose of ascertaining the form and accidents of the
ground, and to make such a plan as will distinguish the
CONTOUR OF GROUND. 149
swelling hill from the sunken valley, and the course of the
rivulet from the unbroken plain.
181. This branch of surveying is called Topography. In
surveys made with a view to the location of extensive w^orks,
the determination of the slopes and irregularities of the ground
is of the first importance : indeed, the examinations would
otherwise be useless.
182. The manner of ascertaining these irregularities is, to
intersect the surface of the ground by a system of horizontal
planes at equal distances from each other ; the curves deter-
mined by these secant planes, being lines of the surface, will
indicate its form at the places of section, and, as the curves
are more or less numerous, the form of the surface will be
more or less accuratelj?^ ascertained.
If such a system of curves be determined, and then pro-
jected or let fall on a horizontal plane, it is obvious that the
curves on such plane will be nearer together or farther apart,
as the ascent of the hill is steep or gentle.
If, therefore, such intersections be made, and the curves so
determined be accurately delineated on paper, the map will
present such a representation of the ground as will show its
form, its inequalities, and its striking characteristics.
183. The subject divides itself, naturally, into two parts.
First, To make the necessary examinations and measure-
ments on the field.
And, 2dly, to make the delineations on paper.
For the former of these objects, the theodolite is the best
instrument ; the common level, however, will answer all the
purposes, though it is less convenient.
Before going on the field, it is necessary to provide a num-
ber of wooden stakes, about two feet in length, with heads.
These stakes are used to designate particular points, and are
to be driven to the surface of the ground. A nail should
then be driven into the head of each of them, to mark its
centre.
184. We shall, perhaps, be best understood, by giving an
example or two, and then adding such general remarks as
will extend the particular cases to all others that can occur.
Let A (PI. 4, Fig. 6), be the summit of a hill, the contour of
150 ELExMENTS OF SURVEYING.
which it is required to represent. At Jl^ let a stake he driven,
and let the axis of the theodolite, or level, he placed directly
over (he nail which marks its centre. From ./?, measure any
line down the hill, as AB^ nsing the telescope of the theodo-
lite or level to arrange all its points in the same vertical plane.
Great care must be taken to keep the measuring chain hori-
zontal, for it is the horizontal distances that are required. At
diflerent points of this line, as a, h, c, d, &c., let stakes be
driven, and let the horizontal distances Jla, ab, be, and cd, be
carefully measured. In placing the stakes, reference must
be had to the abruptness of the declivity, and the accuracy
with which the surface is to be delineated : their differences
of level ought not to exceed once and a half, or twice, the
distance between the horizontal planes of section.
Having placed stakes, and measured all the distances along
the line ^B, run another line down the hill, as JlC, placing
stakes at the points e, /, g, and //, and measuring the hori-
zontal distances *Me, ef, fg, and gh. Run also the line *^D,
placing stakes at i, /, m, and «, and measuring the horizontal
distances Jli, il, hi, and mn.
Each line, ^B, AC, AD, running down the hill from A^
may be regarded as the intersection of the hill by a vertical
plane ; and these secant planes an; to be continued over all
the ground which is to be surveyt'd. If the work is done
with a theodolite, or with a level having a compass, the angles
DAB and BAC, contained by the vertical secant planes, can
be measured ; if it is done with a level, having no needle, let
any of the distances ae, bf, ai, bl, «Sic. be measured with the
chain, and there will then be known the three sides of the
triangles Aae, Abf, Aai, Abl, Slc.
Let now, the difference of level of the several points marked
in each of the lines AB, AD, AC, be determined.
Tn the present example the results of the measurements
and levelling, are —

These data are sufficient, not only to find the intersections
of horizontal planes with the surface of the hill, but also for
delineating such curves of section on paper.
Having drawn on the paper the line AB, lay off the angle
BAC = 2 5% and the angle BAD = 30°. Then, from a con-
venient scale of equal parts, lay off the distances Aa, ah, be,
cd, Ae, ef, fg, gh, Ai, il, Im, and mn.
Let it be required that the horizontal planes be at a dis-
tance of eight feet from each other. Since A is the highest
point of the hill, and the difference of level of the points A
and a, is 12 feet, the first plane, reckoning downwards, will
intersect the line traced on the ground from A to B, between
A and a. Regarding the descent as uniform, which we may
do for small distances without sensible error, we have this
proportion ; as the difference of level of the points A and a,
is to the horizontal distance Aa, so is 8 feet, to the horizontal
distance from A to where the first horizontal plane will cut
the line from A to B. This distance being thus found, and
laid off from A to o, gives o, a point of the curve in which
the first plane intersects the ground. The points at which it
cuts the line from A to C, and the line from A to D, are de-
termined similarly, and three points in the first curve are thus
found.
By the aid of the sector, the graphic operations are greatly
facilitated. Let it be borne in mind, that the descent from A
to a, is 12 feet, and that it is required, upon the supposition
152 ELEMENTS OF SURVEYING.
of the descent being uniform, to find that part of the distance
corresponding to a descent of 8 feet. Take the distance from
Ji to a, in the dividers, and open the arms of the sector until
the dividers will reach from 12 on the line of equal parts, on
one side, to 12 on the line of equal parts, on the other. Then,
without changing the angle, extend the dividers from 8 on
one side, to 8 on the other ; this will give the proportional
distance to be laid off from Jl to o. Or, if the dividers be
extended from 4 to 4, the proportional distance may be laid
off from a to 0.
If the distances to be taken from the sector fall too near
the joint, let multiples of them be used ; as for instance, on
the French sectors, let the arms be extended until the dividers
reach from 120 on the one, to 120 on the other, then 80 or
40 will be the proportional numbers. Other multiples may
be used, though it is generally more convenient to multiply
by 10.
The second plane is to pass 8 feet below the first, that is,
16 feet below A, or 4 feet below a, a being 12 feet below A.
Take the distance ah in the dividers, and extend the sector,
so that the dividers will reach from 8 to (the descent from a
to b being 8 feet) 8, or from 80 to 80; then, the distance from
4 to 4, or from 40 to 40, being laid off from a to p, gives p, a
point of the second curve.
The difference of level between a and h being 8 feet, and
the difference of level between a and p being 4 feet, the dif-
ference of level between p and h must also be 4 feet : hence,
the third plane will pass 4 feet below 6, and q, determined as
above, is a point of the third curve.
The difference of level between h and c being 9 feet, and
consequently between q and c, 5 feet, the fourth plane will
pass 3 feet below c, and r is a point of the fourth curve.
The difference of level between c and d being 11 feet, the
difference of level between r and </ is 8 feet ; so that the fifth
plane will pass through c?, which is consequently a point of
the fifth curve.
The points at which the horizontal planes cut the lines
drawn from A to C, and from A to D, are determined in a
manner entirely similar. Having thus made as many diverg-
ing sections from the point A as may be necessary, and found
the points in which they are cut by horizontal planes, the
CONTOUR OF GROUND. 153
horizontal curves of section can be described through the
several corresponding points. These curves being represented
on paper, their curvature shows the form of the surface of the
hill in the direction of a horizontal line traced around it ; and
the distances between them, the abruptness or gentleness of
the declivity. The numbers (8), (16), &c. show the vertical
distances of the respective planes below the point A.
Having drawn the horizontal curves, the next thing to be
done is so to shade the drawing that it may represent accu-
rately the surface of the ground. This is done by drawing a
system of small broken lines, as in the figure, perpendicular
in direction to the horizontal curves already described. In
all topographical representations of undulating ground, the
lines of shading are drawn perpendicular to the horizontal
curves.
, 185. If it be required to show a profile of the ground, let
the vertical plane passing through Jl and B be revolved about
its intersection with a horizontal plane passing through d.
Erect perpendiculars at r, c, q^ b, p, a, o, and A, to the line
BA, and make them equal to the respective distances of these
points above the horizontal plane passing through d, viz. at r,
8 feet, at c, 11, at q, 16, at b, 20, at p, 24, at a, 28, at o, 32,
and at A, 40 ; and through the extremities of the perpen-
diculars so determined, let a curve be traced : this curve will
be the curve of the hill from d to A.
186. This method of finding the form of the surface of a
hill, is perhaps the best, when the hill slopes gradually from
its summit, and the declivity is sufficiently gentle to measure
down it. If the surface were that of an undulating plain,
the following method is preferable.
Measure a horizontal line, as AB (PL 4, Fig. 7), running
along one side of the ground to be surveyed. At the ex-
tremities A and B, erect the perpendiculars AD and BC, and
produce them until all the land to be surveyed shall be in-

sure the horizontal distances JiE, EF, FG, and GB ; and on
the line DC, the distances !>//, ///, IL, and LC, respeciivehj
equal to the distances on JIB: that is, DH—JIE, HI -EF,
&c. The distances AE, EF, &c. are regulated by the ine-
qualities of the ground, being less if the changes in the sur-
face are considerable, and greater if the changes are nearly
uniform. In the present example, they are 100 feet each,
which, upon ordinary ground, would render the work tole-
rably accurate.
Let stakes be driven at ./?, E, F, G, B, C, L, /, //, and D.
Measme now the line »^D, and place stakes at convenient
distances, as a, b, c, and d : place stakes also along the other
lines EH, FI, GL, and BC, at suitable points, and measure
the respective distances Ef, fg, &c. It is best to use the tel-
escope of the theodolite or level, in order to run the lines
and place the stakes truly. In placing the stakes, it should
be borne in mind, that the dilTerence of level of either two
that follow each other, ought not to be very great ; and also,
that they ought not to be on the same horizontal plane.
After the stakes are all placed, and the distances measured,
let the differences of level of all the points so designated be
found. In the present example, the results of the measure-
ments are —

Let the surface be now intersected by a system of hori-
zontal planes at 3 feet from each other, — the first plane being
3 feet above the point D. The point h being 9 feet above D,
and the point c, 2 feet, the first plane will intersect the line
AD between h and c : let the proportional distance be found,
as in ihe last example, and one point u, of the first cune,
will be known. The point // being 7 feet above D, the plane
will cut the line DC between // and J), and finding the
proportional distance as before, a second point, v, of the first
curve, is determined. Now, in drawing this curve, it will be
borne in mind, that the point h is but 4 feet above D, and
consequently but 1 foot above the first curve, so that the curve
muet run from u towards h, and then turn around to the
poini V. The curve is maked (3), which is the number of
feet that it is above the lowest point, and similarly for the
156 ELEMENTS OP SURVEYING.
Other curves of the figure ; their number showmg their dis-
tance in feet above D. Around the point d, there is a small
curve, also marked (3). By inspecting the table, it will be
seen that cZ is 4 feet above D, and that the ground descends
from d towards D and c : d \s therefore a small knowl, the
top of which is cut off by the first plane. To show that the
ground descends from d, even below the first curve (3), a
plane is passed 1 foot below the first plane, or 2 feet above
D ; the curve of section is marked (2).
The second of the system of curves, or the one marked (6),
must cut the line JID between h and c, the line EH between
/ and g, the line FI between k and /, and also between I
and /; it also cuts EH again between h and H, and the line
DC between fZ" and D.
The third curve, or the one passing 9 feet above D, passes
through 6, cuts the line EH between E and /, the line Fl
between i and k; thence it passes to p, and thence to the
line DC, crossing it between / and L. There is also another
curve determined by this plane, since it passes through the
points C and q, leaving the points t and s below it. This
curve runs from C to p, and from p to q, as drawn in the
figure.
The fourth curve, marked (12), intersects the line AD
between a and h, EH between E and /, FI at i, GL at m,
and BC at B. There is also another curve lying around
the point L : for the plane cuts GL between p and L, the
line DC between C and L, and again between / and L.
The fifth curve, marked (15), cuts AD at a, EH between
E and /, and AB at F. The sixth curve, marked (18), cuts
AD between A and a, and AB between A and E. The
proportional distances in all these cases are found as in the
first example.
In looking on the little map that has been made, it is
clearly indicated by the curves and shading, that the ground
slopes from A to c, thence rises to d, and then slopes to D.
It also slopes from A along the line AB ; from E in the
directions / and i, from F in the directions i and m, from G
in the directions m and J5, and from B in the direction Bqs.
The ground also slopes from L to p, thence to I and /i, and
along to curve (2), and the point D : and on the other side
10 t and s.
CONTOUR OF GROUND. 157
187. Thus far, we have said nothmg of a plane of reference,
which is any horizontal plane to which the levels of all the points
are referred. In the first example, the plane of reference was
assumed through the point A (PI. 4, Fig. 6), and tangent to
the surface of the hill : in the second example, it was taken
through D, the lowest point of the work.
188. After having compared all the levels with any one
point, the highest and the lowest points are at once discovered,
and the plane of reference may be assumed through either
of them. As, however, in comparing the heights of objects,
the mind most readily refers the higher to the lower, it is con-
sidered preferable to take the plane of reference through the
lowest point. We say, for example, that the summit of a
hill is 200 feet above a given plain, and not that the plain
is 200 feet below the summit of the hill ; so we say that a
plain is at a given distance above a river, and not that the
river is below the plain. This habit of the mind of referring
the higher to the lower objects, suggests the propriety of
taking the plane of reference through the lowest point, where
there is no other circumstance to influence its selection. If,
however, there are fixed and permanent objects, to which, as
points of comparison, the mind readily refers all others, sucli
as the court-house or church of a village, the market-house
of a town, or any public building or monument, it is best to
assume the plane of reference through some such point ;
for, it must be kept in mind, that the ends proposed in the
construction of maps, are, to present an accurate view of the
ground, its form, its accidents, and the relative position of
objects upon it.
189. When the plane of reference is so chosen that the
points of the work fall on different sides of it, all the refer-
ences on one side are called positive, and those on the other,
negative. The curves having a negative reference are dis-
tinguished by placing the minus sign before the number ;
thus — ( ).
190. In topographical surveys, great care should be taken
to leave some permanent marks, with their levels written on
them in a durable manner. For example, if there are any
rocks, let one or more of them be smoothed, and the vertical
distance from the plane of reference marked thereon : or let
158 ELEMENTS OF SURVEYING.
the vertical distance of a point on some prominent building,
be ascertained and marked permanenily on the building.
Such points shoukl also be noted on the maj), so lliat a pei^son,
ahhough unacquainted with the ground, could by means of
the map, go upon it, and trace out all the points, t( gether
with their difTerences of level.
191. The manner of sliading the map, so as to indicate
\he hills and slopes, consists in drawing the lines of shading
perpendicular to the horizontal curves, as already explained.
192. In making topograpliical surve^^s, the great point is,
to determine the curves which result from the intersection
of llie surface by iiorizontal planes.
Besides the methods of diverging and parallel sections, we
may assume a point on the surface of a hill, place the level
tliere, and run a line of level round the hill, measuring the
angles at every turn or cliange of direction : such a line wi'l
be a horizontal curve. Then, levelling up or down the hill, a
distance equal to the vertical distance between the horizontal
curves, let a second curve be traced; and shnilarly for as
many curves as may be necessary.
This method, however, is not as good as the methods before
explained.
193. Besides representing the contour of the ground, it is
often necessary to make a map which shall indicate the
cultivated field, the woodland, the marsh, and the winding
river. For this, certain characters, or conventional signs,
have been agreed upon, as the representatives of things, and
when these are once fixed in the mind, they readily suggest
the objects for v;hich they stand. Those which are given in
Plates 5 and G, have been ado[.ted by the Engineer Depart-
ment, and are used in all plans .'vnd maps made by the United
States Engineers.
It is very desirable that a uniform method of delineation
should be adopted, and none would seem to be of higher au-
thority than that establisiied by the Topographical Beaureau.
It is, therefore, recommende(i^ that the convention;d signs
given ill Plates 5 and C, be carefully studied and closely fol-
lowed.
OP SURVEYING HARBOURS. 159
CHAPTER VII.
Of Surveying Harbours.
194 There are two objects to be attained m the survey
of a harbour.
1st. To survey the shore along higli or low water mark,
to trace its windings, to note the points and inlets, and to
ascertain and fix the places at which rivers and creeks dis-
charge tlieniselves. And,
2dly. To discover tlie channels, their direction, depth, and
width ; the position of shoals, the depth of water upon them,
the nature of the bottom, and in short, whatever may contri-
bute to easy and safe navigation.
To determine the principal jwints and trace the shore.
195. Having provided a boat and crew, row once or twice
around the harbour, mark tiie more important and prominent
points ; at which, let station-slaves with flags upon them be
erected.
Then, measure a base line, and form a series of triangles,
having their angles at the stations already chosen. Let the
angles of ihese triangles be measured with the tlieodolite,
and their sides calculated; afler whicli, the high or low water
mark may be traced along the shore with the compass, as
hereafter explained.
Let us suppose that Plate G is a map of a harbour to be sur-
veyed.
We see, by inspecting it, that the upper end of the lake at
t/?, the termination of the harbour at 2>, tlie rocks at C, the
point at D, the fisheries at iJ, and tlie two bays at F and G,
are all prominent points. At these points, therefore, let sta-
tion-flags be placed. Then, measure the distance from A to
B, for a base line, and let the work be begun at J2.
Remove the stafTat ,;-7, and place, by means of a plumb-line,
the axis of the theodolite over the station. Then, having
levelled the instrument, bring the 0 of the eyeglass vernier to
coincide with the 0 of the linjl), and tighten the clamp-screw
of the vernier plate. Loosen the lower clanip-scrcw, and luru

the body of the instrument until the telescope comes nearly on
the base line AB : then tighten the clamp-screw K, and by
means of the lower tangent-screw L, and the thumb-screw Z,
bring the intersection of the spider's lines to coincide with
the bottom of the staff at B. Then, direct the lower tele-
scope to the same point, without moving the limb.
Having thus placed the instrument, examine the opposite
vernier, and if it stands exactly at 180^, enter the direction
from A to B^ 00, as in the j5eld notes below.
But if the reading of the opposite vernier exceeds 180^,
enter half the excess for the direction. If the reading is less
than 180^, take half of what it falls short, from 360^, and
enter the remainder for the direction from A to B.
The two verniers are used to avoid any error which might
arise from a defective graduation of the limb, or from an im-
perfect centring. A false centring, is when the centre of the
limb or vernier plate is out of the axis of the instrument, and
w^hen this is the case, it is a fruitful source of error.
Both verniers should be read at every observation, and a
mean between the readings taken for the true direction.
Having thus placed the instrument, loosen the clamp-screw
of the vernier plate, and direct the telescope to station E.
Note the degrees, and take a mean between the readings of
the two verniers for the minutes, and enter the result opposite
direction AE, as in the field notes. Do the same for the
station 6r, and then enter in a column to the right, the angle
formed by the lines which join the stations. The angle will
either be the difference of the readings, or the difference be-
tween 360® and the larger reading, plus the smaller reading.

For this purpose, after having levelled the instrurnetit, add
180^ to the direction from A to B, and place the 0 of the eye-
glass vernier at the point so found. Then clamp the vernier
plate, after which direct both the telescopes to station A. It
is now plain that the line of the limb drawn through 0 and
180'' will coincide with the base line JIB, the o being towards

The measurements which have been made, enable us to
calculate the lengths of the lines joining the several stations.
For, commencing vi^ith the triangle AEB, we know all the
angles and the base line AB ; we can, therefore, find the
sides EB, EA. We shall then know one side and all the
angles of the triangle CEB, and by pursuing the calculation,
the sides of all the triangles can be readily found.
Smce the third angle of a triangle can always be found
when two of the angles are known, it may seem unnecessary
lo measure all the angles. But when the three angles are
measured and their sum found equal to 180°, the work is
proved to be right, and this verification should never be
omitted.
[t is not probable that the sum of the three measured an-
gles will be exactly equal to 180°. But they ought not to
difTer much from it. If each of them be measured several
OF SURVEYING HARBOURS. t
times, and a mean of the measurements be taken, the errors
of observation and of the instrument will be much dimhiished.
196 The method of determining points by a series of con-
secutive triangles, is called the method by triangulation. It
may be extended to any number of triangles, and if the three
angles of every triangle be measured, and the work carefully
verified at each step, there is little danger of error. We have
applied the method only in the survey of a harbour, but it
may be used with equal advantage in all surveys in which
long lines are to be determined, and is, indeed, the only one
that can be relied on, where great accuracy is required.
Of the Manner of using the Compass.
197. The compass is often used in connection with the
theodolite, and although a rude instrument, may yet be relied
on for the shorter lines and smaller parts of a survey. The
following is the manner of keeping the field notes.
Divide a paper into two equal parts, by two parallel lines
near to each other, and consider each part as a separate leal
or page. Each leaf is divided into three spaces, and the
middle one is generally smaller than either of the others,
which are equal.
The notes begin at the bottom of the first page, and run
up the page to the top. They then commence again at the
bottom of the next page, and run up to the top ; thence to
the bottom of the third page, and thus, for as many pages as
the work may require.
When the compass is used in the way we are about to
explain, the distances to objects which lie on the rioht or left
of the courses, are determined by means of offsets.
The beginning of every course is designated in the middle
column b}^ o, and the bearing is entered directly above. The
other figures of the middle column, express the distances from
the beginning of each course to the oflfsets, and those in the
side columns indicate the lengths of the oflfsets, or the dis-
tances to objects on the right or left of fhe compass lines.
The stations, at which the compass is placed, are designated
by 0 in the middle column, and the bearing of each course is
entered directlv above.
164
ELEMENTS OF SURVEYING.
To explain more definitel}^ the manner of using the com
pass on the field, let us suppose that we have determined,
with the theodolite, the prominent parts of the harbour. Place
the compass at .^ (Plate 6), and take the bearing of the line
^E, which is S 12° W.
Enter this bearing at A. Then measure along the line
AE any distance, as Aa equal to 130 yards, and make an
ofi'set to the lake, which we measure and find to be 50 yards.
Enter the 130 in the middle column, and as the lake lies on
the right (in going from A to E), we insert the 50 in the
right hand column.
We then measure along the line AE to b, 350 yards from
A. Here we make a second oflTset to the lake, and find it to
be equal to 100 yards. Having entered the distances in the
notes, we measure to q, the point where the line AE crosses
the creek, and w^e enter the distance from A, Alb yards.
At rf, we lay off an offset on the left, to the pond, 70 yards :
at e, an offset to the mouth of the creek, 150 yards : and at
E, where the course terminates, an offset to the lake, of 160
yards. The entire distance from .^ to E is 800 yards.
At E, w^e take the bearing to H, which is N 50® E. Hav»
ing measured along this line to/, 315 yards, we make an
offset to the pond, on the left, of 50 yards, and to the shore,
on the right, of 90 yards. Having entered these distances,
OF SURVEYING HARBOURS. 165
we recommence the notes at 315 below, which we suppose U)
be at the bottom of the second page. Having reached H^
the extremity of the course, we enter the entire distance from
jG, 680 yards. We next take the bearing to /, S 52*^ E. Wc
then measure the distances to m, n, p, and /, and enter them,
together with the offsets, as in the notes.
198. It is also well to make, in the columns on the right
and left, such sketches of the ground, fields, houses, creeks
and rivers, as will afford the means of making an accurate
delineation on paper.
199. In making the plan of the harbour, it might be found
convenient to use the plain-table in connexion with the theod-
olite and compass. For example, we might place the plain-
table at G, and having fixed stations at the principal points
of the sliore, between G and F, we would sight to each of
them : then remove the table to F, and do the same for that
station : we should thus determine the points between F and
G, with reference to the line GF,
Of Plotting,
200. The lines of the triangles determined with the theodo-
lite, can be plotted in the manner already explained. It would
be better, however, to use the instrument which we are about
to describe, and which is called
THE CIRCULAR PROTRACTOR.
201. This instrument consists of a brass circular limb (PI,
2, Fig. 4), of about six inches in diameter, with a moveable
index AB, having a vernier at one extremity A, and a milled
screw at the other extremity B, with a concealed cog-wheel
that works with the cogs of the limb, and thus moves the
index JIB about the centre of the protractor. At the centre
of the protractor is a small circular glass plate, on which two
lines are cut ; the point of their intersection, is the exact
centre of the instrument. The limb is generally divided to
half degrees ; the degrees are numbered from 0 to 360.
At the 0 point, and at the opposite extremity of the diameter
passing through that point, are small lines on the inner edge
of the limb; the two extremities of the diameter, perpendicular
to this latter, are also designated in the same way.
166 ELEMENTS OF SURVEYING.
Two angular pieces of brass, each having a small and
sharp steel pin at its extremity, are fastened to the index,
and revolve freely around the lines ab and cd. The small
screws, a, b, c, and d, move them in the directions of the lines
abf cd, for the purpose of bringing the steel pins exactly into
the line which passes through the 0 of the index and the
centre of the protractor.
To adjust them to their places, place the centre of the pro-
tractor over a marked point, and the 0 of the index to the 0
of the limb. Then mark the place of the index by the pins :
after which, turn the index 180°, and see if the pins will mark
the same points as before. If they do, the index is adjusted ;
if they do not, correct the error with the screws a, b, c, and d.
To lay off an angle with the Protractor.
202. Let its centre be placed over the angular point, and
the diameter passing through 0 and 180°, on the given line.
Turn the screw that works the index, until the 0 of the ver-
nier coincides with the division corresponding to the given
angle ; then let the angular brass pieces be turned down ;
the points dotted by the steel pins will show the direction of
the required line.
If this line does not pass through the angular point, the
pins are out of place, and must be adjusted.
First Method of Plotting.
203. Suppose it were required to make the plan of the
harbour on a scale of 450 yards to an inch.
Divide the length of the base line ^B, which we will sup-
pose equal to 1140 yards, by 450, and the quotient 2.53 will
express the length which is to represent the base line on the
paper (Art. 33).
Draw an indefinite line ^B, to represent the base, and
having chosen any point, as .^, for the first station, lay off
2.53 inches to B. The other extremity of the base line will
thus be determined.
Then, place the circular protractor at A, and lay off the
angle BAE, and then the angle EAG. Next, place the
protractor at B, and lay off the angles ABE and EBC.
The intersection of the lines AE and BE will determine
OF SURVEYING HARBOURS. 167
the station E. Let the protractor be then placed at this
point, and all the angles of station E, laid down.
The point G, where EG intersects AG, and the point C,
where EC intersects BC, will then be found.
By placing the protractor at C and G, we can determine
the points D and F, when the place, on the paper, of all the
stations will be known.
To vuiite the work done with the compass, spread the com-
pass-notes before you, and draw through A a line to represent
the meridian. This line makes an angle of 12^ with the
course JlE.
Then, lay off from the scale the distances Aa, Ab, Aq, Ac,
Ad, Ae, and at the several points erect perpendiculars to AE.
Lay off on these perpendiculars the lengths of the offsets, and
the curve traced through the points so determined, will be
the margin of the lake.
At E, draw a parallel to the meridian through A, and lay
down the course EH, which makes an angle of 50° with the
meridian. Then, lay down the several distances to the off-
sets, and draw the offsets and lay off their lengths. Do the
same for the course HI, and all the compass-work will be
plotted.
Had there been work done with the plain-table, it could
easily be united to that done with the theodolite.
Second Method of Plotting.
204. Place the centre of the protractor near the centre of
the paper, and draw a line through the points 0 and 180^.
This line will have the same position with the circular pro-
tractor that the base line AB had with the limb of the
theodolite.
Lay off then from the 0 point an arc equal to the direction
from A to E, also an arc equal to the direction AG, and
through the centre point, and the points so determined, draw
lines. Lay off in succession, in a similar manner, the direc-
tions taken at all the stations ; and through the centre point,
and the points so determined, draw lines, and designate each
by the letters of the direction to which it corresponds.
Now, since all the lines drawn on the paper have the same
position with the circular protractor, as the corresponding
168 ELEMENTS OF SURVEYING.
lines on the ground have with the limb of the tlieodolite, it
follows that each direction will be parallel to its corresponding
line upon the ground.
Hence, any line may be drawn parallel to that passing
through 0 and 180°, to represent the base line AB. Having
drawn such a line, and marked a point for the station Jl, lay
off the length of the base, and the extremity will be the
station B.
Through A and B^ so determined, draw parallels respec-
tively to the lines corresponding to the directions JIE and
BE, and the point of intersection will determine station E.
Through B and E draw parallels to the lines which corre-
spond to the directions BC, CE, and their point of intersection
will determine station C. Through C and E draw lines
parallel to the lines corresponding to the directions CE and
ED, and the point of intersection will determine D. In a
similar manner we may determine the stations F and G.
Of surveying a harbour for the purpose of determining the depth
of loater, <^c.
205. When a harbour is surveyed for the second object, viz.,
for the purpose of ascertaining the channels, their depth and
width, the positions of shoals, and the depth of water thereon,
other means must be used, and other examinations made in
addition to those already referred to.
Let buoys be anchored on the principal shoals and along
the edges of the channel, and using any of the lines already
determined as a base, let the angles subtended by lines drawn
from its extremities, to the buoys respectively, be measured
with the theodolite. Then, there will be known in each
triangle the base and angles at the base, from which the dis-
tances to the buoys are easily found ; and hence, their posi-
tions become known.
Having made the soundings, and ascertained the exact
depth of the water at each of the buoys, several points of the
harbour are established, at which the precise depth of the water
is known ; and by increasing the number of the buoys, the
depth of the water can be found at as many points as may be
deemed necessary.
206. If a person with a theodolite, or with any other in-
strument adapted to the measurement of horizontal angles, be
OF SURVEYING HARBOURS. 169
stationed at each extremity of the base Hne, it will not be
necessary to establish buoys. A boat, provided with an an-
chor, a sounding line, and a signal flag, has only to throw iis
anclior, hoist its signal flag, and make the sounding, while
the persons at the extremities of the base line measure the
angles ; — from these data, the precise place of the boat can
be determined.
207. There is also another method of determining the
places at which the soundings are made, that admits of great
despatch, and which, if the observations be made with care,
affords results sufficiently accurate.
Having established, trigonometrically, three points which
can be seen from all parts of the harbour, and having provided
a sextant, let the sounding be made at any place in the har-
bour, and at the same time the three angles subtended by lines
drawn to the three fixed points, measured with the sextant.
The problem, to find from these data the place of the boat
at the time of the sounding, is the same as example 6, page 74.
It is only necessary to measure two of the angles, but it is
safest to measure the third also, as it affords a verification
of the work.
The great rapidity with which angles can be measured with
the sextant, by one skilled in its use, renders this a most ex-
peditions method of sounding and surveying a harbour.
The sextant is not described, nor are its uses explained in
these Elements, because its construction combines many phi-
losophical principles, with which the surveyor cannot be sup-
posed conversant.
208. There is yet another method of finding the soundings,
which, although not as accurate as those already explained,
will, nevertheless, afford results approximating nearly to the
truth. It is this : — Let a boat be rowed uniform.ly across the
harbour, from one extremity to the other of any of the lines
determined trigonometrically. Let soundings be made con-
tinually, and let the precise time of making each be care-
fully noted. Then, knowing the length of the entire line,
the tPme spent in passing over it, as also the time of making
each of the soundings, we can easily find the points of the
line at which the several soundings were made ; and hence,
the depth of water at those points becomes known. Sound-
170 ELEMENTS OF SURVEYING.
ings may thus be made along any number of known lines,
and a comparison of the depths found on different lines, at or
near their points of intersection, will show with what degree
of accuracy the work has been done.
209. If the soundings are made in tide-waters, the time of
high tide must be carefully noted, as also the precise time
of making the sounding, so that the exact depth at high or
low water may be known. It is considered preferable to re-
duce the soundings to high-water mark, and the number of
feet which the tide rises and falls should be noted on the map.
210. Having plotted the work done with the theodolite, as
also the outline of the harbour traced with the compass, it re-
mains to delineate the bottom of the harbour ; and this is done
by means of horizontal curves (Chap. VI), which have already
been used to represent broken or undulating ground.
Let the plane of reference be taken through high-water
mark, or to coincide with the surface of the water at high
tide. The accuracy with which the bottom of the harbour is
to be delineated, will guide us in fixing the distance between
the horizontal planes of section.
The first horizontal plane should be passed at a distance
below the shallowest point that has been sounded, equal to
the number of feet fixed upon for the distance between the
planes of section ; and the curve, in which it intersects the
bottom of the harbour determined as in Chapter VI. And
similarly, for the other horizontal planes of section.
Having thus delineated the bottom of the harbour, and noted
on the map the distance of each intersecting plane below the
plane of reference, let such lines be drawn as will indicate the
channels, shoals, sunken rocks, and direction of the current.
In the example given in plate 6, soundings have been made
in three directions from the sand-bar in the harbour, and also
from the rocky shore across to the light-house.
PRINCIPLES OF NAVIGATION. 171
CHAPTER VIII.
Of Navigation.
1. We have given, in the preceeding chapters of this work,
various apphcations of Trigonometry. We propose, in the fol-
lowing chapter to explain the best methods of determining the
place of a ship at sea. This application constitutes the science
of Navigation.
There are two methods of determining the place of a ship at
sea.
1st. When a ship departs on her voyage, if we note her
courses and the distance sailed, we may, at any time, by means
of Plane Trigonometry, determine her place very nearly.
2nd. By means of observations on the heavenly bodies and
the aid of Spherical Trigonometry, we may determine with great
accuracy, the exact place of the ship. This method is called
Nautical Astronomy.
The first part of Navigation, viz. the cases which can be
solved without the aid of observations on the heavenly bodies,
will be alone treated of in this chapter.
2. The earth is nearly spherical. For the purposes of Navi-
gation it may be considered as perfectly so. It revolves round
one of its diameters, called the aocis, in about twenty-four hours.
3. The great circle, whose poles are the extremities of the
axis, is called the equator'. The poles of the equator are called
the poles of the earth — the one is called the north pole, and the
other the south pole.
4. Every great circle which passes through the poles cuts the
equator at right angles, and is called a ineindian circle. Every
place on the surface of the earth has its own meridian ; but for
the purposes of Geography and Navigation, all these meridians
are reckoned from a particular meridian, which is called \hQji7'st
meridian. The English have fixed on the meridian of Green-
wich Observatory for the first meridian.
5. The longitude of any place is the arc of the equator inter-
cepted between the meridian of that place and the first meridian,
and is east or west, according as the place hes east or west of
the first meridian.
6. The difference of longitude of two places is the arc of the
equator included between their meridians ; this arc is equal to
the difference of longitudes when they are of the same name,
and to their sum, when they are of different names.
7. The latitude of a place is its distance from the equator
172
ELEMENTS OF SURVEYING.
measured on the meridian of the place, and is north or south ac-
cording as the place lies north or south of the equator.
8. 'I'he small circles drawn parallel to the equator, are called
parallels of latitude. The arc of any meridian intercepted be-
tween the parallels passing through any two places, measures
the difference of latitude of those places; this difference is found
by subtracting their latitudes wdien they are of the same name,
and by adding them when they are of different names.
9. The sensible horizon of any place is an imaginary plane,
supposed to touch the earth at that place, and to be extended to
the heavens. A plane passing through the centre of the earth,
and parallel to the sensible horizon, is called the rational hori-
zon. The north and south line, is the intersection of the plane
of the meridian circle with the sensible horizon, and the line
which is drawn perpendicular to this, is called the east and west
line.
10. The course of a ship, at any point, is the angle which her
track makes with the meridian. So long as the course is un-
changed, the ship w^ould sail in a straight line, provided the
meridians were truly parallel ; but as the meridians bend con-
stantly toward the pole, the direction of her path is continually
changing, and she moves in a curve called the i^humh line. The
course of a ship is indicated by the mariner's compass.
11. The marine7'^s
compass consists of a
circular card, whose
circumference is di-
vided into thirty-two
equal parts called
pom^5; each point be-
ing subdivided into
four equal parts call-
ed quarter points.
To the under side
of this card a slender
bar of magnetized
steel, called a needle,
is permanently at-
tached. The direc-
tion of the needle
corresponds to the
diameter NS. The
diameter EW, at right angles to NS, is intended to indicate the
east and west points. The points of the compass are thus read:
beginning at the north pohit, and going east, we say, north and
PHINCIPLES OF NAVIGATION, 173
by eastj north north east, north east and by north, north east;
and so on, round the compass, as indicated by the letters.
The card being permitted to turn freely on the pin, on which
it is poised as a centre, the line NS will always indicate the
true magnetic meridian, but this, as we have seen it Art. 153,
page 127, is not the true meridian, and hence, the variation must
always be allowed for.
On the interior of the compass box, in which the card swings,
are two marks, a and b, which lie in a line passing through the
centre of the card, and the compass box is so placed that this
line shall be parallel to the keel of the ship. Consequently, if a
be placed towards the bow of the vessel, the point which it
marks on the card will show the compass course, for the line
NS is always north and south, and EW east and west. The
course is generally read to quarter points, and as a quadrant con-
tains eight points, each point will be equal to 60° --8= 11° 15';
and a quarter point ==11° 15' ^4 = 2° 48' 45". The table oi
Rhumbs, after the Traverse Table, shows the degrees of each
course to quarter points.
1 2. A ship's rate of sailing is determined by means of an in-
struments, called the log, and an attached line called the log line.
The log is a piece of wood in the form of a sector of a circle,
the rim of which is loaded with lead, so that when it is heaved
into the sea it assumes a vertical position. The log line is so
attached as to draw the log square against the water, that it may
not be drawn along after the ship as the line unwinds from the
reel, by the ship's forward motion.
The time in which the log line unwinds from the reel, is
noted by a sand-glass, through which the sand passes in half a
minute; that is, in the one hundred and twentieth part of an
hour.
For convenience, the log line is divided into equal parts,
marked by knots, and each part is equal to the one hundred and
twentieth part of a nautical or geographical mile.*
Now, since half a minute is the one hundred and twentieth
part of an hour, and each knot measures the one hundred and
twcnticlli part of a mile, it follows that the number of knots
reeled off while the half minute glass runs out, will indicate how
fast the ship sails per hour.
* A geogra):)hical mile is one minute, or one-sixtieth of a degree, measured on the
equator. Taking the diameter at 7916 English miles, the geographical mile will
be about C079 feet ; that is, about oi.e-sixth greater than the English mile, which is
6280 feet.

Of Plane Sailing*
13. Let the diagram
EPQ represent a por-
tion of the earth's sur-
face, P the pole, and
EQ the equator. Let
AB be any rhumb hne,
or track described by a
ship in saiUng from A
to B,
Conceive the path of
the ship to be divided
into very small parts, and through the points of division draw
meridians, and also the parallels of latitude b'b, c'c, d'd, e'e, and
B'B: a series of triangles will thus be formed, but so small that
each may be considered as a plane triangle.
In these triangles, the sum of the bases
Ab' + be + cd! 4- de' + e/= AB\
which is equal to the diiference of latitude between the points
A and B. Also,
b'b-{-cc-\-d'd-\-eeA-fB' = BB\
which is equal to the distance that the ship has departed from
the meridian AB'P, and is called the departure in sailing from
A to B.
Therefore, the distance sailed, the
difference of latitude made, and the
departure, are correctly represented by
the hypothenuse and sides of a right
angled triangle, of which the angle op-
posite the departure is the course.
When any two of the four things
above named are given, the other two
can be determined. This method of
determining the place of a ship reduces
all the elements to the parts of a plane
triangle, and hence is called plane
sailing.

Of Traverse Sailing,
14. When a ship, in going. from one place to another, sails on
different courses, it is called Traverse Sailing. The determi-
nation of the distance and course, from the place of departure to
the place of termination, is called compounding or working the
traverse. This is done by the aid of the " Traverse Table,"
which has already been explained, and the method is in all
respects similar to that adopted in the Prob. of Art. 147, p. 115.
EXAMPLES.
1. A ship from Cape
Clear, in lat. 51° 25' N.,
sails, 1st, S. S. E. \ E. 16
miles; 2nd, E. S. E. 23

below, in which w^e enter
the courses, from the table
of rhumbs, omitting the sec-
onds, and then enter the lat-
itudes and departures, taken
from the traverse table, to
the nearest quarter degree.
Thus, in taking the latitude
and departure for 25° 18'
we take for 25i°. The dif-
ference of latitudes gives the
line A G, and the difference
of departures the line GF.

Therefore the direct course is S. 18° 13' E., and the distance
62.83 miles.
Of Plotting,
15. There is yet another method of finding the direct course
and distance, much practiced by seamen, although it does not
afford a high degree of accuracy. It is a method by plotting,
which requires the use of a mariner's scale and a pair of dividers
One of the scales marked on the mariner's scale, is a scale of
chords, commonly called a scale of rhumbs, being divided to every
quarter point of the compass ; and there is also a second scale
of chords divided to degrees. Both of these scales are con
structed in reference to the same common radius, so that the
chords on the scale of rhumbs correspond to those on the scale of
marked chords. The manner of using the scales will appear in
plotting the last example.
To construct this traverse, describe a circle with a radius
equal to the chord of 60° and draw the meridian NS. Then
take from the line of rhumbs the chord of the first course 2^
points, and apply it from »S* to 1, to the right of A^^S*. since the
course is southeasterly, and draw >S'l ; take, in like manner, the
chord of the second course, 6 points, from *S to 2, and lay it off
also to the right of the meridian line. Apply the chord of the
third course, 5| points, from 8 to 3, to the left of the meridian;
the fourth course, 7} points from N to 4, to the left of NS, this
course being northwesterly; and, lastly, apply the chord of the
fifth course, 5| points, from S to 5, to the right of NS, and join
all the lines as in the figure.
In the direction .41, lay off the distance ^17/— 16 miles from
a scale of equal parts, and through the extremity H, draw HC
parallel to A2, and lay off HC — 2S miles. Draw CD parallel
to .43, and lay off CD = 36 miles; then draw DE parallel to .44,-
and lay off 12 miles; and lastly draw EF parallel to A5, and
lay off 41 miles, and F will be the place of the ship. Hence,
we conclude that AF will be the distance made good, and GAF
will be the course. -.q
ITS ELEMENTS OF SURVEYING.
Applying, then, tlie distance AF to the scale of equal parts,
we ftnd it equal to 62| miles ; and applying the chord Sa to the
scale of chords we find the course GAF=l'^l°.

These examples will, perhaps, suffice to illustrate the princ»
pies of plane sailing.
The longitude, made on any course, cannot be determined by
these methods, for this being the arc of the equator intercepted
between two meridians, cannot be found under the supposition
that the meridians are parallel.
The most simple case of finding the difiference of longitude is
when the ship sails due east or due west : this is called Parallel
Sailing.
PRINCIPLES OF NAVIGATION.
179
Parallel Sailinsc.
16. The entire theory of parallel sailing is comprehended in
the following proposition, viz.
The cosine of the latitude of the parallel, is to the distance
rurif as radius to the difference of longitude.
Let JQ/f represent the equa-
tor, and FDN any parallel of
latitude : then, CI will be the
radius of the equator, and EF
the radius of the parallel.
Suppose FD to be the dis-
tance sailed, then the difference
of longitude will be measured
by /Q, the arc intercepted on
the equator. Then, since sim-
ilar arcs are to each other as
their radii (Bk. V. Prop. xi.
Cor.), we have,
EF : CI :: dist. FD : diff. long. IQ.
But EF is the sine of PF, or cosine of FI, the latitude, and
CI is the radius of the sphere : hence,
COS. lat. : R : : distance . diff. longitude.
Corollary. If we denote by D the distance between any two
meridians, measured on the parallel whose latitude is L ; and
by D^ the distance between the same meridians measured on the
parallel whose latitude is U, the arcs will be similar, and W€
shall have (Bk. V. Prop. xi. Cor.),
COS. L : D : : cos. L' : D\
that is, COS. L : cos. L' : : D : D'.
Hence, when the longitude made on different parallels is the
same, the distances sailed are proportional to the cosines of the
parallels of latitude.
By referring to Th. V. page 43, we see that in any right an-
gled triangle
R : COS. angle at base : : hyp. : base,
or cos E : R :: EG : EC;
and by comparing this with the proportion,
cos. lat. : R : : dist. ■ diff. long.
We see, that if one leg of a right angled tri-
angle represent the distance run on any paral-
lel, and the adjacent acute angle be made equal
E
180 ELEMENTS OF SURVEYING.
to the degrees of latitude of that parallel, then the hypothenuse
will represent the difference of longitude. It follows therefore,
that any problem in parallel sailing, may be solved as a simple
case of plane sailing. For, if we regard the latitude as the
course, the distance run as the base, the difference of longitude
will be the hypothenuse of the corresponding right angled
triangle.

PRINCIPLES OF NAVIGATION. 181
Middle Latitude Sailing.
1 7. Having seen how the longitude which a ship makes when
sailing on a parallel of latitude may be determined, we come
now to examine the more general problem, viz. to find the lon-
gitude which a ship makes when sailing upon any oblique rhumb.
There are two methods of solving this problem, the one by
what is called middle latitude sailing, and the other by Merca-
tor^s sailing. The first of these methods is confined in its ap-
plication, and is moreover somewhat inaccurate even where
applicable ; the second is perfectly general, and rigorously true ;
but still there are cases in which it is advisable to employ the
method of middle latitude sailing, in preference to that of Mer-
cator's sailing. It is, therefore, proper that middle latitude sail-
ing should be explained, especially since, by means of a correc-
tion to be hereafter noticed, the usual inaccuracy of this method
may be rectified.
Middle latitude sail-
ing proceeds on the
supposition that the de-
parture or sum of all
the meridional distan-
ces, h^h, &c, d^df &c.
from O to T, is equal
to the distance M'M of
the meridians of O and
T, measured on the
middle parallel of lati-
tude between O and T.
The middle latitude is half the sum of the two extreme lati-
tudes, if they are both of the same name, and to half their dif-
ference if they are of contrary names.
This supposition becomes very inaccurate when the course is
small, and the distance run great ; for it is plain that the middle
latitude distance will receive a much greater accession than the
departure, if the track OT cuts the successive meridians at a
very small angle.
The principal approaches nearer to accuracy as the angle O
of the course increases, because then as but little advance is
made in latitude, the several component departures lie more in
the immediate vicinity of the middle parallel M'M. But still, in
very high latitudes, a small advance in latitude makes a con-
siderable difference in meridional distance ; hence, this principle
is not to be used in such latitudes, if much accuracy is required.
By means, however, of a small table of corrections, con-
stnicted by Mr. Workman, the imperfections of the middle lat-
182
ELEMENTS OF SURVEYING.
itude method may be removed, and the results of it rendered in
all cases accurate. This table w^e have given at the end of this
work.
The rules for middle latitude sailing may be thus deduced.
We have seen, in the first case of plane sail-
ing, that if a ship sails on an oblique rhumb
from O to T, that the hypothenuse OT will
represent the distance ; O [P the difference of
latitude, and T'T, the departure. Now, by
the present hypothesis, the departure T'T is
equal to the middle parallel of latitude between
the meridians of the places sailed from and ar-
rived at : so that the difference of longitude of
these two places is the same as if the ship had
sailed the distance T'T on the middle parallel
of latitude. The determination of the differ-
ence of longitude is, therefore, reduced to the case of parallel
sailing: for, T'-'T now representing the distance on the parallel,
if the angle T^TO" be made equal to the latitude of that parallel,
we shall have, by the last case, the difference of longitude rep-
resented by the hypothenuse (yT. We therefore have the
following theorem :
I. In the triangle C/TT ^
COS. a TV : TT :: R : TO';
that is,
COS. mid. lat. : departure : : R : diff. longitude.
II. In the triangle C/TO
sin. O' : OT :: sin O : O'T ;
that is, since sin. O^rcos. CTT
COS. mid. lat. : distance : : sin. course : diff. longitude.
III. In the triangle OTT^, we have
R : tangent O : : OT : TT ;
comparing this with the first proportion, and observing that the
extremes of this are the means of that, we have
O'T
COS. O'TT : tangt. 0;
OT
that is,
diff. lat. : diff. long. : : cos. mid. lat. : tangt. course.
These three propositions comprise the theory of middle lati-
tude sailing ; and when to the middle latitude sailing, the proper
correction, taken from Mr. Workman's table, is applied, these
theorems will be rendered accurate.
In the table of pages 93 and 94, the middle latitude is to be
found in the first column to the left. Then, along in the hori-
zontal line, and under the given difference of latitude, is inserted
PRINCIPLES OF NAVIGATION. 183
the proper correction to be added to the middle latitude to obtain
the latitude in which the meridian distance is accurately equal to
the departure. Thus, if the middle latitude be 37°, and the dif-
ference of latitude 18°, the correction will be found on page 94,
and is equal to 0° 40^.
EXAMPLES.
1. A ship, in latitude 51° 18' N., longitude 22° 6' W., is
Dound to a place in the S. E. quarter, 1024 miles distant, and
in lat. 37° N. : what is her direct course and distance, as also
the difference of longitude between the two places ?

In this operation the middle latitude has not been corrected,
so that the difference of longitude here determined is not without
error. To find the proper correction, look for the given middle
latitude, viz. 44° 9', in the table of corrections, the nearest to
which we find to be 45° ; against this and under 14° diff. of lat.
we find 27', and also under 15° we find 31', the difference be-
tween the two being 4'; hence, corresponding to 14° 18' the
correction will be about 28', Hence, the corrected middle lati-
tude is 44° 37', therefore,

therefore, the error in the former result is about 6 j miles.

18. It has already been observed, that when a ship sails on an
oblique rhumb, the departure, the difference of latitude, and the
distance run, are truly represented by the sides of a right angled
triangle.
Thus, if a ship sails from A to i?, the
departure B^B w^ill represent the sum oi
all the very small meridian distances, or
elementary departures, b% p'p, &c. ; the
difference of latitude AB^ vi^ill represent,
in like manner, the small differences of
latitude Ab'^ b'p', &c ; and the hypothe-
nuse AB, will express the sum of the
distances corresponding to these several
differences of latitude and departure.
Each of these elements is supposed to
be taken so small, as to form on the sur-
face of the sphere a series of triangles, differing insensibly from
plane triangles.
Let Ab^b represent one of these elementary triangles ; b^b will
then be one of the elements of departure ; and Ab' the corres-
ponding difference of latitude. Now, as b^b is a small arc of a
parallel of latitude, it will be to a portion of the equator or of a
meridian containing an equal number of degrees, as the cosine
of its latitude is to radius (Art. 16). This similar portion of
the equator, or of the meridian, will be the difference of longi-
tude between 6^ and b.
Let us now suppose Ab to be prolonged until the perpendicular
p^p shall become equal to the difference of longitude between b"
and b: then,
bb^ will be to p^p, as the cosine of the latitude of b% to radius.
But, b'b : p'p : : Ab' : Ap' :
hence, Ab' : Ap' : : cos. lat. of b'b : radius ;
that is, if the latitude be so increased that p'p shall become the
true difference of longitude^ then,
true diff. lat. Ab' : increased lat. Ap' : : cos. lat. : radius.
The increased latitude Ap' is called the meridional difference
of latitude. Denoting, therefore, the true difference of latitude
PRINCIPLES OF NAVIGATION. 185
by d^ the increased or meridional difference of latitude by D, the
latitude of h'h by Z, and the radius by 1, which is, indeed, the
radius of the tables of natural sines, and we shall have
d ' D : : cos. I : 1,
which gives
D=d secant /, since L=sec. l.
COS. /
If then, we know the latitude I of the beginning of a course,
and the true difference of latitude d of the extremity of the
course, we can easily find the meridional latitude D correspond-
ing to that course.
Conceiving each elementary distance to be increased in this
manner, giving the meridional differences of latitude on the line
AC^, the sum of all the corresponding elements will be the entire
meridional departure during the course.
To represent, therefore, the difference of longitude due to any
departure, as B B, and to its corresponding difference of latitude
AB^, we must produce AB' lill AC is equal to the meridional
difference of latitude ; the perpendicular C^C will then be the
difference of longitude actually made in sailing from A to B.
The determination of AC requires the determination of all its
elementary parts. If d be taken equal to V, we shall have from
the equation above
D=y sec I. or D — sec. Z,
it being understood that I expresses minutes or geographical miles.
From ibis equation, the value of D, corresponding to every
minute of /, from the equator to the pole, may be calculated ;
and from the continued addition of these there may be obtained,
in succession, the meridional parts corresponding to V, 2^, 3^, 4^
&c. of true latitude, and when registered in a table, they form a
table of meridional parts, given in all books on Navigation.
The following may serve as a specimen of the manner in
which such a table may be constructed, and, indeed, of the man
ner in which the first table of meridional parts was actually
formed by Mr. Wright, the proposer of this valuable method.
Mer. pts. of l^=:nat. sec. V.
Mer. pts. of 2^=:nat. sec. T+nat. sec. 2\
Mer. pts. of 3^==nat. sec. T + nat. sec. 2^ + nat. sec. 3^
Mer. pts. of 4^=:nat. sec. T + nat. sec. 2''+nat. sec. 3^ +&c.
Hence, by means of a table of natural secants we have
Nat. Sees. Mer. Pts.
Mer. pts. of V= 1.000000 =1.0000000
Mer. pts. of 2^=1.0000000+1.0000000 = 2.0000002
Mer. pts. of 3^=2.00000024-1.0000004 = 3.0000006
Mer. pts. of 4"= 3.0000006+ 1.0000007=4.0000013 &c.

ELEMENTS OF SURVEYING.
There are other methods of construction, but this is the most
simple and obvious. The meridional parts thus determined, are
all expressed in geographical miles, because in the general ex-
pression
D=l' sec. I.
r is a geographical mile.
Having thus formed the table of meridional parts, if we enter
it, and find the meridional parts corresponding to the latitudes of
the place left and the place arrived at, their difference will be
the meridional difference of latitude, or the line AC^ in the dia
gram. The difference of longitude CC may then be found by
the following proportion.
I. As radius is to the tangent of the course, so is the meridional
difference of latitude to the difference of longitude.
But if the departure be given instead of the course, then,
II. As the true difference of latitude, is to the departure, so is the
meridional difference of latitude to the tangent of the course.
Other proportions may also be deduced from the diagram.
EXAMPLES.
As an example of Mercator's or rather Wright's, sailing, let us
take the following:
1. Required the course and distance from the east point of
St. Michael's to the Start point : the latitudes being 37° 48' N.,
and 50° 13' N., and the longitudes 25° 13' W., and 3° 38' W.
Start Point, lat. 50° 13' N. Mer. pts. 3495
St. Michael's, lat. 37° 48' N.
True difference of lat. 12° 25'

Diff. in miles 745
Mer. pts. 2453
Mer. diff. 1042
Diff. oflongT~2l° 35'

Diff. in miles 1 295
Now, let us suppose that we have sailed
from Ato B: we shall then know A5' equal
true diff. lat. = 745 miles; J. C^ = merid-
ional diff. of lat.=rl042; and C'C= the
difference of longitude equal to 1295
miles. It is required to find the course
B^ABy and the distance AB.

Mercator's Chart.
Mercator's Chart is a Map constructed for the use of Navi-
gators. In this chart all the meridians are represented by straight
lines drawn parallel to each other, and the parallels of latitude
are also represented by parallel straight lines drav^^n at right
angles to the meridians.
The chart may be thus constructed. Draw on the lower part
of the paper a horizontal line to represent the parallel of latitude
which is to bound the southern portion of the chart. From a
scale of equal parts, corresponding in size to the extent of the
map to be made, lay off, on this line, any number of equal dis-
tances and throiigh the points draw a series of parallels to rep-
resent the meridians.
Then draw a line on the side of the map, and for the second
parallel of latitude, find from the table of meridional parts the
meridional difference of latitude corresponding to the degrees
between the first and second parallel, and lay off this distance
for the interval between the two parallels. Then find the meri-
dional difference between the second and third, and lay it off in
the same way for the third parallel, and so on, for the fourth,
fifth, &c.
A place whose latitude and longitude is known, may be laid
down in the same manner; for it will always be determined by
the intersection of the meridian and parallel of latitude.
If the chart is constructed on a small scale the divisions on
the graduated lines, may be degrees instead of minutes ; and
the meridians and parallels may be drawn only for every fifth
or tenth degree.
We have already seen (Art. 18.), that the meridional difference
of latitude bears a constant ratio to the difference of longitude,
so long as the course remains unchanged : and hence we see
that on Mercator's chart, every rhumb will be represented by a
straight line.

Line of Meridional Parts on Gunter's Scale.
This scale corresponds exactly with the table of meridional
parts, excepting, that in the table the circle is divided to minutes,
while the scale is divided only to degrees. A scale of equal parts
is placed directly beneath the scale of meridional parts ; if the
former corresponds to divisions of longitude, the latter will rep-
resent those of latitude. Hence, a chart may be constructed
trom these scales by using the scale of equal parts for the lines
01 longitude, and the scale of meridional parts for those of
