Planting, Harvesting, etc, According to the Signs of the Zodiac: Now Available!
This short, obtusely-titled booklet is nonetheless absolutely worth reading for those interested in the topic of astrology; I don't know of another comparable work; one which suggests that surgical and medical acts should be relegated to an astrological timeline. The agricultural tips in here are a bit more mystic than in most works with similar, almanac-esque content, but are definitely fun to read.
At the end it contains a relatively mundane twelve-month zodiac and the basic traits for each sign. Notably, it does include the concept of "cusp" signs (days overlapping two signs.) For example, I am on the cusp of Capricorn and Aquarius. This has significance in some zodiacal interpretations, but is not regarded as valid by some others.
