This book represents the work of Heber J. Smith, a homeopathic physician in Boston who was born in 1842. He was a professor of materia medica at Boston University and a practicing astrologer who was a teacher of Evangeline Adams. Legend says that Julie Pontin, a rival of Evangeline, paid Heber $150 for a typewritten copy of this material-a large sum in the early 20th century. In addition to the value of the astrological experience and knowledge presented in this book, it is also representative of the thinking of the astrologers of the time, which was decidedly deterministic. Some of the words and phrases are quaintly archaic when viewed from the 21st century, and the writing style is also representative of an earlier time. Nevertheless, much astrology can be learned from the author’s insights into the transiting planets. He also includes examples from his own life regarding the effects of transits and directions. Included are chapters on the transits of Mercury, Venus, Sun, Mars, Jupiter, Saturn, Uranus and Neptune in both favorable and unfavorable aspect to other planets.
