To make a horoscope, (even houses) by means of the circle of days on wonder wheel.
For A. M., subtract the hour of birth from noon hour, and count back from date of birth three circles for every hour (or one circle for every 20 minutes,) and mark the point arrived at "10," or Jot the date on a slip of paper.
For P. M., multiply the hour of birth by three, and count forward from date of birth as many circles as the answer to the sum calls for, and mark the point arrived at. 10. This "10" shows the date when the Sun crosses the cusp of 10th house, the house of honor and profession. The corresponding degree of the zodiac is the meridian, or M. C, of the horoscope.
From that point, (either A. M. or P. M. birth) divide the circle into 12 houses of six. circles each, and mark them, starting from 10 and around in regular order of months) as follows: 11, 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, and then you will have your horoscope of birth, and the several divisions or houses will relate to the affairs (as stated in the four corner circles of wonder wheel) as per number of the division. Where the number is will also show the date that the Sun enters each house, and the sign and degree of sign will show what part of the zodiac the Sun is in. If planets have previously been placed in circle of days, then they will appear in the house they were in at birth, and the Sun will be in conjunction with them when it reaches their place, moving through a circle every five days. For instance: Born Sept. 5, (any year) at 9 A. M., 9 from 12-3 hours - three circles for each hour - 9 circles count back then 9 circles from Sept 5, and it brings us to July 20. That point represents the 10th, house of the horoscope. August 20, would be the 11th house; Sept. 20th, the 12th house; Oct. 20th, 1st house; Nov. 20th. 2nd house; and so on around. The 10th house then would be lst deg. of Leo, 11th, 1st deg. of Virgo, 12th, 1st deg. of Libra, 1st, 1st deg. of Scorpio, etc.
If a planet, then, was in the 20th deg. of Libra, it would be in the 12th house, and the Sun each year would be in conjunction with it about the 10 th of October. Square with it 10th of June, (90 days) Trine Feb. 10th, (120 days) Opposition April 10th, (180 days). If date was Sep. 5, at 9 P. M., then we would say, nine multiplied by three makes 27, and count 27 circles forward, that would bring us to Jan. 20th as the point of the 10th house. Then we would keep right on. and the 11th house would be Feb. 20th, 12th; March 20th, etc., and as before, 90 days from a planet would be a square, 120, a trine and so on.
Horary figures for Any Time may be constructed by this same law as given, but horary figures are not so regular, and require finer mathematics, as horary matters are transitory and depend upon the irregular changes of the Moon and obliquity of the Earth; mere passing shadows of life events. Tour horoscope can be made in the circle of days on the wheel, or by drawing circle on a slip of paper, or by our skeleton wonder wheel.
All other Signs, Planets, and Aspects, must be judged from their own special qualities and positions, precisely in the manner, as given regarding Aries and Mars.
The wonder wheel, like the zodiacal heavens or the horoscopal earth, is divided into 12 different departments, so it may be Judged either as the solar heaven with Sun in centre, or the mundane heaven, with Earth in centre, according to your requirement. With Sun in centre it would be heliocentric; with Earth in centre it would be geocentric. In either case the Sun is in the zodiacal sign opposite to
