Evangeline Adams wrote of her long and highly successful career as an astrologer. She described the people who were her clients, many of them nationally or world famous, discussing their problems, the astrological advice she gave them, and the results of her advice. Practicing for some forty years, first in Boston and from 1899 in New York until her death in 1932, Miss Adams guided and advised over one hundred thousand people through their troubles, and the confusions and complexities of life.

She based her advice on the astrological chart, which contains an intricate pattern of information applicable only to the individual for whom it is drawn. To say that a person is a Leo, or a Capricorn, may be true in itself, but this is only the sign in which the Sun was placed at his birth. It is an astrologically important point, but only one among a great many others of equal or often of much greater importance.
