You are lucky to have a copy of this booklet. I re-published his older works in a book called Carl Payne Tobey's Collected Works on Astrology. It includes these pamphlets and some of his older publications out of print. There is a 1962 chapter comparing Aries versus Scorpio that he called mate signs. These mate signs follow Hellenistic Planetary Order.

The Collected Works is an ebook under Apple's Itunes iBooks or it can be purchased hardcopy from www.learnastrologynow.com.

The confusion of Pluto ruling Scorpio versus Aries is from the original Hellenistic Planetary Order when Mars ruled them both.

The martial, military, violence nature of these two signs are similar but are not the same. That is why CP Tobey wrote so much about the differences.

The nature of Saturn/Uranus to Capricorn/Aquarius is much more distinct and easier to differentiate. The nature of Jupiter/Neptune to Sagittarius/Pisces is easier to differentiate too.

The Pluto Aries article hasn't been updated since 1997. It needs to include the Roman Catholic scandal of child abuse by priests that was revealed during Pluto (children) in Sagittarius (religion) and then the expansion of financlal institutions (Sagittarius) into speculation (Pluto) until 2007. When Pluto entered in Capricorn 2007 there was a hint of a financial collapse that was shored up by the Fed but the massive collapse happened in 2008 when Pluto permanently entered Capricorn.
