IN erecting a horoscope there are simple problems of two separate kinds. The first set

of problems maps the positions of the signs of the zodiac in relation to the earth. The

second set of problems maps the positions of the various planets in relation to the

zodiacal signs.

These problems are quite distinct from each other because the positions of the

zodiacal signs are calculated from **Sidereal Time**, while the positions of the planets

are calculated from **Equivalent Greenwich Mean Time**. Most of the trouble

experienced by beginners arises from failing to remember that the kind of time used

for mapping the zodiacal signs is not the same as the time used for mapping the

planets.

Both the Sidereal Time of Birth and the Equivalent Greenwich Mean Time of Birth

are derived from still a third kind of time, called **Local Mean Time**. Because it is

necessary first to find the Local Mean Time before either of the other kinds of time

can be ascertained, and therefore before either sign positions or planet positions can

be computed, I call the Local Mean Time the **DOMINANT FACTOR**.

From this Dominant Factor, or Local Mean Time, the Sidereal Time of Birth is

calculated. Because this Sidereal Time of Birth is the key to the positions of the

zodiacal signs, I call Finding the Sidereal Time of Birth the **FIRST KEY
PROBLEM**.

From this Dominant Factor, or Local Mean Time, the Equivalent Greenwich Mean

Time Interval is calculated. Because this Equivalent Greenwich Mean Time Interval

is the key to the positions of the planets, I call Finding the Equivalent Greenwich

Mean Time Interval of Birth the **SECOND KEY PROBLEM**.

Yet before attempting the actual work of erecting a horoscope the student should

know what a horoscope is, what data is required to erect it, the meaning of the

symbols commonly employed, and how to add and subtract both Longitude and

Time. These can be conveniently handled as **PRELIMINARY EXPLANATIONS**.

It should now be clear that erecting a horoscope divides itself according to the natural

sequence of the work into four well marked divisions that are based upon)

**PRELIMINARY EXPLANATIONS, DOMINANT FACTOR. FIRST KEY
PROBLEM, and SECOND KEY PROBLEM.**

In the complete work there are eleven separate processes or steps. When you become

accustomed to them some of these steps will be passed over so rapidly as hardly to be

noticed; yet unless short cuts are used these eleven steps are always taken in the

erection of a complete horoscope.

The time for which the chart is erected may be before noon or it may be after noon, the

place may be east, or it may be west, of a standard meridian, or there may be other

variations. In this one lesson I have taken into consideration all the various

conditions and circumstances an astrologer is apt to meet, and have formulated rules

and given examples having reference to them all. You will find twenty-seven rules.

So many rules, and the examples illustrating them, may give you the impression that

erecting a horoscope is a formidable task. Yet as a matter of fact, in the erection of

any one chart only a part of the rules are used. Even the following of the eleven

necessary steps quickly becomes almost automatic, and you will soon do most of the

calculations mentally about as quickly as you can conveniently enter the results in

the map.

Instead of being a complicated task, all that is really necessary to erect a horoscope is

the knowledge that the signs are placed in the map from the Sidereal Time of Birth,

that the planets are placed in the map from Equivalent Greenwich Mean Time

Interval of Birth, that both of these different times are computed from the Local

Mean Time of Birth, and the use of addition, subtraction, and common sense.

### PRELIMINARY EXPLANATIONS

The word horoscope is derived from Greek words meaning hour view. It is a map of

the heavens showing the positions of the planets and zodiacal signs as viewed from

some particular place at some particular time. There are, therefore, three distinct

factors necessary for the erection of a horoscope of birth of a child or other event:

A–Astronomical data from which the positions of the signs and

planets may be calculated.

B–The place of birth from which the heavens are to be viewed.

C–Time of birth–Year, Month, Day of Month, and Time of

Day, A. M. or P. M.–when the heavens are thus to be viewed.

(A) The necessary astronomical data for calculating the positions of the signs and

planets may be found in an Astronomical Ephemeris for the year of birth.

Astronomical ephemerides commonly cover but a single year each, and may be had

for each year since 1850.

The data for determining the relation of the heavens to the particular place may be

found by consulting a Table of Houses for the Latitude of the place. A Table of

Houses is good for any year, and need only approximate the latitude of birth.

Raphael’s1ephemeris contains not only the positions of all the planets for mean

noon, Greenwich, for each day of the year covered, but also contains an aspectarian, a

table of houses for several important places, and a table of proportional logarithms.

(B) The location of the place for which the horoscope is erected may be ascertained

by consulting a common atlas or geography and finding its Latitude and Longitude.

Longitude is expressed in ° (degrees), ‘ (minutes), and ” (seconds) E (east) or W

(west) of Greenwich. Latitude is expressed in °, ‘, and “, N (north) or S (south) of the

equator. Where unusual precision is required geocentric latitude is used, but the

latitude of the common map is precise enough for all ordinary purposes.

(C) There are various systems for recording time which are or have been in use.

Unless the time used is known, a correct chart cannot be erected. This matter of what

kind of time was used at any given date is of utmost importance, but is so complicated

that it requires a special volume for treatment. Such a volume is published entitled,

World Daylight Saving Time.

As the astronomical data given in the ephemeris is calculated for Mean Time, unless

the time of birth is given in terms of local mean time it becomes necessary to convert

the recorded time into local mean time.

The use of local mean time requires that every place having a different longitude

should have a different time. As this is a nuisance, Standard Time is now used in

most parts of the world. In the United States the country is divided into four

Standard Time Zones each containing 15ï¿½ longitude. The Standard Meridian for Eastern

Time is 75°, or 5 hours, west; the Standard Meridian for Central Time is 90°, or 6

hours, west; the Standard Meridian for Mountain Time is 105°, or 7 hours, west;

and the Standard Meridian for Pacific Time is 120°, or 8 hours, west. Eastern

Canada has a further zone, called Atlantic Time, which is but 4 hours west.

Theoretically, all places 7½° east and 7½° west of a standard meridian should keep

the same time. As a matter of fact, railroad divisions and natural boundaries greatly

influence the actual place where time changes are made. Furthermore, the dividing

line where such changes of time take place has not remained constant, but has shifted

along with railroad changes and the development of certain regions. The map on at the

front of this lesson (page 2), gives the zones and places of time change as they exist

at the present time. But if a birth is near these places of time change, much pains

should be exercised to ascertain just what time was used in recording the birth.

Standard Time was adopted throughout the United States, theoretically, Nov. 18, 1883, at Noon;

and in Great Britain in 1880. Actually it was not used in many places until considerably later.

Previous to these dates each place used its own time, the Local Mean Time.

On all dates after the adoption ofStandard Time, when the time given is that of the

ordinary watch or clock, it becomes necessary to convert this standard Time to Local Mean Time.

To still further complicate matters, during and following the great war, daylight

saving time was adopted in many countries. It was in general use in the U. S. during

1918 and 1919, and is still used in some sections of the country. As if this were not

confusion enough, in some towns in the eastern U. S. at the present, there are two

kinds of time in use. Daylight Saving Time has been made legal, but as it so

complicates schedules, the railroads continue to use Standard Time. To get the time

of birth right, inquiry must be made as to which time was used in the record.

The U. S. used Daylight Saving in 1918 from March 31 to October 27, and in 1919

from March 30 to October 26 but where continued the change date varies. When the

birth is timed by Daylight Saving, it becomes necessary to subtract one hour from the

clock time to get the Standard Time. Then in the usual way, Standard Time may be

converted into Local Mean Time.Then again, in some countries, notably Russia,

the Julian Calendar was used up to the time of the Revolution in 1917. Even here

there are exceptions, as some places on the Black Sea used the calendar of their

neighbors.

When, however, the date is given Old Style, as it was reckoned in Russia,

it must be converted into the Gregorian Calendar, or New Style, because the ephemeris

is calculated New Style. This is done by adding 12 days to Old Style dates

occurring in the 19th Century, and by adding 13 days to Old Style dates since 1900. Thus,

Jan. 2, 1916, Old Style, is the same as Jan. 15, 1916, New Style. The Horoscope,

consequently, should be erected for Jan. 15.

### How to recognize astronomical symbols, and

the signs that always occur opposite each other.

Table I at the front of this lesson (page 7) gives the names of the zodiacal signs, the symbol

for each sign, the number of each sign in the zodiac (not its vibratory number), and the signs

that are always opposite each other. This table should be thoroughly memorized.

Table II (page 7)gives the names of the planets, the symbol for each planet,

and–with the exception of the Sun which is given first because most important–the

order of their speed through the zodiac, the Moon being fastest in motion. This table

also should be well memorized.

### How to add and subtract

Longitude, Right Ascension, Mean

Time and Sidereal Time.

Geographical longitude and celestial right ascension (R.A.)2are expressed in °, ‘, and “.

Zodiacal longitude is expressed in S, °, ‘, and “.

Table III (see Table page 7) gives the necessary data. It should be memorized.

### Rule 1.

–To add Long. or R.A. Add the “, and if the sum exceeds 60″ subtract 60″ from it, there

mainder being ” and each 60″ being called 1′ and added to the ‘ column.Add the ‘ including

that carried over from the ” column and if the sum exceeds 60′,

subtract 60’ from it, the remainder being ‘ and each 60’ being called 1° and added to

the ° column. Add the °, including that carried over from the ‘ column, and if the sum

exceeds 360° subtract 360 from it. The remainder being °, and each 360° being called

a circle and discarded.

Example (1). Given Perth, W. Australia, with a long. 115° 54′ E. and St. Johns,

Newfoundland, with a long. 52° 42’ W to find how far in long. they are apart.

### Rule 2.

–To subtract Long. or R.A. Subtract ” from “, and if the minuend be too small,

borrow 1′ from the ‘ column, and calling it 60″ add to the minuend ” column. Subtract

‘ from ‘, and if the minuend be too small borrow 1° from the ° column and calling it

60’ add to the ‘ in the minuend. Subtract ° from ° and if the minuend be too small add

the full circle of 360° to the ° in the minuend to make subtraction possible.

Example (2). Traveling in a westerly direction from San Francisco with a long. of

122° 26′ W., how far is it in long. to Buenos Aires with a long. of 58° 18’ W.?

Mean Time and Sidereal Time are expressed in h (hours). m (minutes), and s

(seconds). Table IV, giving this, should be memorized.

### Rule 3.

–To add Mean Time proceed as in adding long. except that if the total sum exceeds

12h, 12h should be subtracted from it, calling the difference P.M. of the same day if

A.M. was given, or A.M. of the following day if P.M. was given.

Example (3a). Given a mean time of 11h 58m 32s A.M. Jan. 6, to find the mean time

6h 23m 52s later.

Example (3b). Given a mean time of 10h 24m 31s P.M. Jan, 6, to find the mean time

8h 42m 35s later.

### Rule 4.

–To subtract Mean Time Proceed as in subtracting long. except that if the

minuend be too small in h, 12h must be added to it, and the difference is then P.M. of

the day before if A.M. time is given, or A.M. of the same day if P.M. time is given.

Example (4a). Given a mean time of 8h 42m 36s A.M. Jan. 6, to find the mean time

10h 38m 56s earlier.

Example (4b). Given a mean time of 7h 37m 22s P.M. Jan. 6, to find the mean time

9h 21m 58s earlier.

### Rule 5.

–To add or subtract Sidereal Time (S.T.) proceed as with mean time except that

when the sum is in excess of 24h, 24h must be subtracted, the remainder being the

required S.T.; and when the minuend is too small to permit subtraction, 24h must first

be added to it.

Example (5a). Given a S.T. of 19h 24m 29s. to find the S.T. 6h 4m 31s later.

Example (5b). Given a S.T. of 4h 27m 18s, to find the S.T. 5h 41m 28s earlier.

### Rule 6.

–To add Zodiacal Longitude proceed as in geographical longitude except that if

the sum exceeds 30°, subtract 30° from it, each 30° being called One Sign and added

to the sign column. If the signs exceed 12, subtract 12S from the sum, being careful to

note that Pisces is both sign 12, and sign 0.

Example (6). Given Pisces (12S) 28° 4′ 29″. to add 4° 16′ 33″ to it.

### Rule 7.

–To subtract Zodiacal Longitude proceed as in subtracting geographical

longitude except that if the minuend be too small in S, 12S must be added to it, and if

too small in °, 30° (1S) must be borrowedfrom the S column.

Example (7). Given Aries 4° 32′ 16″, tosubtract 20° 33′ 19″ from it.

#### THE DOMINANT FACTOR

### STEP 1. How to Find the Local

Mean Time.

–One complete revolution of the earth on its axis, which is the time between two

successive transits of the sun’s semi-diameter across the same meridian, measures 24

hours. In the complete revolution the 360° of geographical longitude measuring the

earth’s circumference pass under the sun at meridian. Dividing 360° by 24, gives 15°

that pass under the sun at meridian every hour. Dividing this hour of 60 minutes by 15

gives 4 minutes as the time required for 1° longitude to pass under the sun at

meridian.

Thus in the prevalent method of reckoning, the Standard Meridians of Time, starting

at Greenwich, are exact multiples of 15° E. or W., there being a difference of just 1h

in time between successive Standard Meridians. A glance at the maps at the front

of this lesson (pages 1 and 2), will indicate these various meridians and time zones.

Now if the place for which the chart is to be erected is exactly on one of the Standard

Meridians the Local Mean Time (L.M.T.) is the same as the time recorded by the

clock. But since standard time came into use, if the place is either E. or W. of a

standard meridian, the clock time must be converted into L.M.T.

Clocks west of a Standard Meridian are FAST.

Clocks east of a Standard Meridian are SLOW. And

as 1° longitude is the equivalent of 4m time, as

shown above, the number of ° E. or W. of the

Standard Meridian may be converted into time

merely by multiplying by 4 and calling the result

minutes.

### Rule 8.

–When Standard Time is given to find the

L.M.T. at a place west of a Standard Meridian

multiply the ° distant from the standard by 4, calling

the result minutes, multiply the minutes by 4 to get

seconds, and subtract from standard time.

Example (8). Given a standard time at San Francisco of 5h 00m A.M., to find the

L.M.T. San Francisco is 122° W. 26″ long. The Pacific Standard Meridian is 120° W.

Difference in long. is 2° 26′.

2° 26′ X 4 gives 9 minutes 44 seconds

### Rule 9.

–When Standard Time is given to find the L.M.T. at a place east of a Standard

Meridian multiply the ° distant from the standard by 4. calling the result minutes, the

minutes by 4 to get seconds, and add to the standard time.

Example (9). Given a standard time at New York of 5h 32m P.M., to find the L.M.T.

New York is 73° W 57′ long. The Eastern Standard Meridian is 75° W 00′.

Difference in long. is 1° 3′. 1° 3′ X 4 gives 4 minutes 12 seconds.

*Line 19 Correction:
Because the earth rotates at a rate of 1° in 4 minutes, the solar day is longer than the
sidereal day by a little less than 4 minutes (3m56s). A correction of 9.86 secs per hour of
EGMT (3m56s/ 24h= 9.86s) must be made*

#### FIRST KEY PROBLEM

### STEP II. How to Find the Sidereal

Time of Birth.

–The celestial equator is the projection of the earth’s equator in the heavens. There

are 360° in the celestial equator. To measure any circle a starting point is necessary.

The starting point for measuring along the earth’s equator is the Meridian of

Greenwich. The starting point for measuring along the celestial equator is the point

where the sun crosses it each year moving north in the spring of the year. This point is

the vernal equinox called 0° Aries.

The distance E. or W. of Greenwich as we have seen may be expressed in °, ‘, and “,

or in h, m, and s. So, likewise, the distance E. or W. of 0° Aries may be expressed in °,

‘, and “, and so expressed is called Right Ascension (R.A.). Or it may be expressed in

h, m, and s, and then is called Sidereal Time (S.T.). R.A. in the heavens corresponds

to geographical longitude. Sidereal Time is the distance along the celestial equator

from 0° Aries expressed in Time. The S.T. at noon of any day represents the distance

of the point on the celestial equator from 0° Aries that is on the Mid Heaven (M.C.) at

noon of that day.

Knowing the S.T.–distance from 0° Aries in time–on the M.C. at noon, and that the

whole celestial equator must pass the M.C. in 24h, it is easy to calculate the

S.T.–distance from 0° Aries–that is on the M.C. at any moment of that day. The

INTERVAL of time since noon added to the S.T. at noon, or the INTERVAL of time

before noon subtracted from the S.T. at noon, must give the required S.T. This is the

exact distance of the point on the M.C. from 0° Aries.

The Sidereal Time at noon for each day at Greenwich is given in the ephemeris for

the year in which the date occurs.

### Rule 10.

**–To find the Sidereal Time when the L.M.T. is after noon,** consult the ephemeris

for that year and day and to the S.T. there given for noon add the L.M.T., or

INTERVAL after noon. For greater precision see correction below.

### Rule 11.

**–To find the Sidereal Time when the L.M.T. is before noon,** consult the

ephemeris for that year and day and from the S.T. there given for noon subtract the

INTERVAL between the L.M.T. and noon. For greater precision see correction

below.

**Correction of Sidereal Time for Precision**

–As Sidereal Time increases at the rate of approximately 4 minutes a day where

precision is required a correction of 9.86s (roughly 10s) per hour must be made both

for longitude from Greenwich, and for the INTERVAL between L.M.T. and noon.

The separate correction for L.M.T. is best performed by always ADDING 9.86s per

hour to the INTERVAL between L.M.T. and

noon. The separate correction for longitude

may best be performed by adding 9.86s

per hour to S.T. if west, and

subtracting 9.86s per hour from S.T.

if east, longitude.It is easier in actual practice to make

BOTH corrections at one operation

after finding the E.G.M.T.INTERVAL (Step IV) by adding

9.86s per hour that the INTERVAL

E.G.M.T. is past noon to the S.T., or

subtracting 9.86s per hour that the

INTERVAL E.G.M.T. is before noon from

the S.T. See Chapter 8.

For the sake of clearness of detail the examples here perform the two corrections

separately.

Example (10). Given a L.M.T. of 5h 36m 12s P.M. Jan. 2, 1920, at New York, to find

the Sidereal Time.

Example (11). Given a L.M.T. of 4h 50m 16s A.M. March 4, 1920, at San Francisco,

to find the Sidereal Time.

#### HOUSE CUSPS

### STEP III. How to Place Signs and

Degrees Upon House Cusps.

–The dividing line between one house and another is called its cusp. The houses are

numbered in example chart No. 1 at the front of this lesson (page 6).

### Rule 12.

–In a table of houses for the latitude of birth find in its column the S.T. of birth.

Opposite this time, or its nearest approximate, will be found the sign and degree to be

placed on each house cusp from 10th to 3rd. When these have been entered into the

chart on their appropriate cusps, place the same degree of the opposite sign on the

opposite house cusp. Signs opposite each other are given in Table I.

Example (12) Given a S.T. of Birth at New York of 0h 21m 16s, to place the zodiacal

signs and degrees in the chart.

New York is 40° 43′ N. Latitude. Consulting the table of houses for this latitude

given in Raphael’s ephemeris I find the nearest S.T. given as 0h 22m 02s. Opposite

this S.T. under column marked 10, I find 6°, and looking up this column I find this to

be of the sign Aries. I therefore place 6° Aries on the cusp of the 10th house in the

chart.

Opposite the same S.T. I find 13° Taurus on the 11th house cusp, 21° Gemini on the

12th house cusp, 23° 24′ Cancer on the 1st house cusp, or Ascendant, 13° Leo on the

2nd house cusp, and 6° Virgo on the 3rd house cusp. And I place them thus in the

chart.

For the 4th house cusp I look in Table I of opposite signs and as Libra is always

opposite Aries I use 6° Libra. For the 5th house cusp I use 13° Scorpio, as Scorpio is

opposite Taurus; on the 6th I use 21° Sagittarius because Sagittarius is opposite

Gemini; on the 7th I use 23° 24′ Capricorn because Capricorn is opposite Cancer; on

the 8th I use 13° Aquarius because Aquarius is opposite Leo; and on the 9th 1 use 6°

Pisces because Pisces is always opposite Virgo. Example chart No. I has been

corrected by Rule 13.

#### Inserting Missing Signs

–Frequently the same sign will be found on more than one house cusp. When this

occurs other signs are missing. These may be found by counting the signs in their

regular order. They should then be entered onthe map in the middle of those houses

where they fall by their natural sequence in thezodiac.Tables of houses may be had

giving thehouse cusp to the nearest tenth of a degree.

Where great precision is required the exactminute on any house cusp may be

found bythe following rule:

### Rule 13.

–To find the exact ‘ on any house cusp:4Look in a table of houses for the latitude ofbirth.

Find (a) the difference between thenearest and the next nearest S.T. of birth.

Find (b) the difference between the True S.T. of birth and the nearest S.T. of birth. Find

(c) the difference between the cusps corresponding to the nearest and the next nearest

S.T. of birth. Then (a): (b) :: (c): ?

Multiply (b) by (c) and divide the product by (a). If the True S.T. of birth is more than

the nearest S.T. add; if less, subtract. Example 13. To find the exact ‘ on the

Ascendant when the S.T. of birth at New York is 0h 21m 16s.

*3 See “Chart Erection Short Cuts and Examples” (last chapter in this book) for latitude correction notes.*

4 For mapping the character, and the type of events which the thought-cells so mapped tend to attract,

achart with the nearest degree on the Ascendant and Midheaven is precise enough. But when it is

desired to progress the positions of the chart to determine WHEN energy from a certain planet will be

added to a group of thought-cells in sufficient volume to attract a specific event, it is essential that the

Ascendant and Midheaven, which are treated as planets, should be calculated to the exact minute of

zodiacal longitude.

#### To Work a Problem In Proportion

–As the product of the means is equal to the product of the extremes, when the two

inner terms are given multiply one by the other and divide the product by the outer

term. When the two outer terms are given multiply one by the other and divide the

product by the inner term. The result is the answer. Such problems are taught in

grammar school, and are essential to astrological work.

–Tables of houses for north latitude may be used for places in south latitude by

adding 12h to the S.T. and using the degrees thus found, but placing opposite signs on

the house cusps. Detailed examples of this will be found in Chapter 8.

#### SECOND KEY PROBLEM

### PLANETS IN SIGNS

#### STEP IV. How to Find the

E.G.M.T. INTERVAL

### Rule 14.

–To find the difference in time between the place of birth and Greenwich,

multiply the ° distant in longitude from Greenwich by 4, calling the product minutes,

and multiply the ‘ by 4, calling the product seconds. Convert into hours and minutes.

Example (14). Given a long. of 73° W 57’ (New York) to find the difference in time

from Greenwich.

73 X 4 equals 292m. 57 X 4 equals 228s. 292m divided by 60 equals 4h, plus 52m

remainder. 228s divided by 60 equals 3m, plus 48s remainder. 4h 52m plus 3m 48s

equals 4h 55m 48s. Ans.

### Rule 15.

–Divide the ° by 15. The quotient is hours, the remainder multiplied by 4 is minutes.

Example (15). Given a long. of 118¼° (Los Angeles) to find the difference in time

from Greenwich.

118¼ divided by 15 equals 7h. The remainder, 13¼ X 4 equals 53m. 7h 53m, Ans.

### Rule 16.

–To find the E.G.M.T. when the place is west of Greenwich, add the difference in

time to the L.M.T., when the place is east of Greenwich subtract the difference in

time from the L.M.T.

Example (16a). Given a L.M.T. of 5h 36m P.M. and a difference in time of 4h 56m

W. (New York), to find the E.G.M.T.

Example (16b). Given a L.M.T. of 10h 02m A.M., and difference in time of 54m E.

(Berlin), to find the E.G.M.T.

Example (16c). Given a L.M.T. of 4h 50m A.M., and difference in time of 7h 53m

W. (Los Angeles), to find the E.G.M.T.

The Interval E.G.M.T. is the number of hours and minutes after noon, called a

PLUS INTERVAL, or the number of hours and minutes before noon, called a

MINUS INTERVAL. Thus in the above examples the E.G.M.T. Interval of (a) is

plus 10h 32m, of (c) is plus 0h 43m. But if the E.G.M.T. is before noon, it must be

subtracted from noon to get the Interval, and the result is then a Minus Interval. Thus

in the above example (b) find the Interval.

### STEP V. How to Find

the-Constant Proportional

Logarithm.

–A table of proportional logarithms is a decimal mathematical table simplifying

difficult problems in proportion. The Constant Logarithm is the number found in a

table of proportional logarithms corresponding to the E.G.M.T. Interval.

### Rule 17.

–To find the Constant Logarithm look in a table of diurnal proportional

logarithms and find the figure corresponding to the E.G.M.T. Interval.

Example (17). Find the Constant Log. for an interval of plus 10h 32m. Interval is 10h

32m. Looking in the table of proportional logarithms in the back of Raphael’s

ephemeris I look down the column marked 10h until it intersects with the horizontal

column marked 32m. There I find .3576. Ans.

### STEP VI. How to Find the Daily

Motion of Any Planet.

–In recent years the swifter planets have their daily motion given for each day in the

latter part of Raphael’s ephemeris.

### Rule 18.

–To find the daily zodiacal motion of any planet, consult the ephemeris for the

two days between which the E.G.M.T. occurs and subtract the less longitude from the

greater in the regular order of the zodiacal signs.5

Example (18). Find the daily zodiacal motion of the Moon Jan. 2, 1920.

*5Pluto’s position is given in Raphael’s ephemeris starting 1934, and in the Pluto ephemeris for earlier
years. Call the days between ephemeris positions (a), the days between ephemeris date and required
date (b), the minutes Pluto moves between these two positions (c), and the motion of Pluto during
required interval (d). Then (a): (b) :: (c) (d).
Thus using the Pluto ephemeris, during the 30 days (a) from December 16, 1919, to January 15, 1920,
Pluto moves 35′ (c). The interval between January 2 and January 15 is 13 days (b). 35 multiplied by
13 and divided by 30 gives 15′ as the motion of Pluto during this interval. As it is retrograde, add
these 15′ to the place of Pluto January 15, and it gives the longitude of Pluto January 2, 1920, as 6
Cancer 36 R.*

### Rule 19.

–To find the daily declination motion of any planet, consult the ephemeris for the

two days between which the E.G.M.T. occurs, and if both are either N. or S.

declination subtract the less from the greater; but if one is N. and the other S.

declination, add the given declinations. If the declination is given only every 2nd or

3rd day the result must be divided by 2 or by 3 to get the daily motion.

Example (19a). Find the daily declination motion of Mercury Jan. 2, 1920.

Example (19b). Find the daily declination motion of Venus Apr. 14, 1920.

### STEP VII. How to Find the

Proportional Logarithm of the

Daily Motion of a Planet.

### Rule 20.

–To find the proportional logarithm of a planet’s daily motion look in a table of

proportional logarithms and find the ° and ‘ corresponding to its daily motion.

Example (20). Find the prop. Log. of the Moon’s daily notion Jan. 2, 1920. Daily

motion (example 18) 14° 48′ 9″. Neglecting the 9″ I consult the table of logarithms in

Raphael’s ephemeris and where the column 14° intersects with 48’ I find .2099. Ans.

### STEP VIII. How to Find the

Motion of Any Planet for the

E.G.M.T. Interval.

### Rule 21.

–To find the distance traveled by any planet during the Interval, add the

Constant Logarithm to the Logarithm of the Daily Motion. This gives the log. of

distance traveled during the Interval.

Example (21). How far in longitude does the Moon travel on Jan. 2, 1920, during a

plus interval of 10h 32m?

Looking in table of logarithms I find that .5675 gives 6° 30′ which is the Answer.

Note: In using logarithms always use the nearest approximate figure.

### STEP IX. To Find the Zodiacal

Longitude of the Planets at Birth.

### Rule 22.

–To find the zodiacal longitude of a planet when the Interval is plus, add its

travel for the interval to the place given in the ephemeris for noon. When the Interval

is minus, subtract its travel for the interval from the place given in the ephemeris for

noon. If, however, the planet is retrograde (marked R at top of column in ephemeris)

reverse this, and subtract for plus interval, and add for minus interval.

Example (22). Find the zodiacal longitude of the Moon Jan. 2, 1920, when there is a

plus E.G.M.T. Interval of 10h 32m.

### STEP X. To Find the Declination

of the Planets at Birth.

### Rule 23.

–To find the declination of a planet when the Interval is plus, add the declination

for the interval to the noon declination if the declination is increasing, subtract if

decreasing. When the Interval is minus, subtract the declination for the interval from

the noon declination if the declination is increasing, add if decreasing. If the

declination changes from N to S or S to N, this must be allowed for.

Example (23). Find the declination of the Moon Jan 2, 1920, when there is a minus

Interval of 2h 14m

The declination of any house cusp, the Moon’s Nodes, or the Part of Fortune is

always that of the Sun when it is in the same sign and degree.

### Rule 24.

–To find the declination of any house cusp, the Moon’s Nodes, or the Part of

Fortune, look in the ephemeris for the position of the Sun in the same sign, degree

and minute, and use this declination8

Example (24). Find the declination of the Ascendant when Cancer 23° 37′ is rising

July 16, 1920, shows the Sun in Cancer 23° 37′ , and on that day it also has

declination N 21° 23′, which is the Answer.

### STEP Xa. How to Find the

Zodiacal Longitude of the Fixed

Stars, the Dragon’s Head and Tail,

and the Part of Fortune.

–The zodiacal positions of the fixed stars may be had from tables made for that

purpose. As they move only 1° in about 72 years their places may be had by

inspection. The house positions of the stars, however, for those having considerable

latitude, require the use of trigonometrical calculations.

Example: What important Fixed Star is nearest the Asc in longitude when Cancer

23° 13′ rises? Looking in Dalton’s “Sixteen Principle Stars” I find on Jan. 2, 1920,

the star Procyon in Cancer 24° 41′ 8″.

The Dragon’s Head is the Moon’s north Node, the Dragon’s Tail is its south Node.

The North Node is calculated from its place as given in the ephemeris as if it were a

planet, and the South Node is always the same degree of the opposite sign.

Example: Find Moon’s Nodes for Jan. 2, 1920, for a plus E.G.M.T. Interval of 10h

32m. Looking in ephemeris for Jan. 2, I find the North Node in Scorpio 22° 17′ . The

South node, therefore, is Taurus 22° 17′ .

*8 Declination of the Angles: Find (a) difference between nearest and next nearest long. In table at the front
of this lesson (page 4). Find (b) difference between nearest long. In table and long. Of Angle. Find (c) difference
between declinations corresponding to nearest and next nearest long. In table. Problem by Logs: (b)
minus (a) plus (c) equals (d) — correction to be made. Add correction to nearest decl. In table if
nearest long. Is smaller than long. Of Angle; if larger, subtract.*

Find decl. Of Ascendant 23° Cancer 15′.

*Subtracting 3′ from 21°N29′ gives 21°N26′ as the Answer*

The Part of Fortune is a point on the ecliptic (zodiac) as far removed from the

Ascendant by longitude as the Moon is removed from the Sun by longitude.

**Rule 25. To find the Part of Fortune, from the sum of the zodiacal
longitudes of the Ascendant and Moon subtract the zodiacal
longitude of the Sun. This difference is the longitude of the Part of
Fortune.**

Example (25). Find the Part of Fortune Jan. 2, 1920, for a plus E.G.M.T. Interval of

10h 32m.

### STEP XI. How to Place the Planets

in the Chart.

### Rule 26.

–The declination of each planet N. or S. having been calculated, it should be

placed opposite its symbol in a column at one side of the chart. See Example

Chart No. 1 at the front of this lesson.

### Rule 27.

–The zodiacal longitude of each planet having been calculated, start with the

Ascendant. Remember the degrees recorded are those above the horizon in this case,

hence if a planet has less degrees of the same sign it must be placed above the house

cusp in the 12th, but if it has more degrees it must be placed in the chart below the

Asc. Then proceed around the chart in the order of sequence of the houses entering

the planets in their signs, placing those having less degrees than the house cusp next

back toward the Ascendant, and those having more degrees than the house cusp in the

house farther removed from the Asc. following the proper order of sequence of

houses.

The Moon’s Nodes, Part of Fortune, and Fixed Stars having little latitude may

be placed in the chart in the same manner. Fixed Stars having much latitude must

be entered by R.A. and Dec. (See Dalton’s Fixed Stars.)

Note: As in thousands of birthcharts erected and progressed to the date of some

event, The Brotherhood of Light Research Department has found no instance where

a Fixed Star, the Moon’s Nodes, or the Part of Fortune has been required to explain

either the character of an individual or any event that has happened to him, we make

no use of them. It must be remembered that the positions in a chart of Uranus,

Neptune and Pluto were unknown to earlier astrologers, who doubtless became

aware of influences apart from the seven naked eye orbs, and accounted for them as

best they could.
