The Timber Hitches list almost immediately in "CHAPTER 21: HITCHES TO SPAR AND RAIL (RIGHT-ANGLE PULL)", only preceded there by 3 Half Hitch base forms.  The context begins with typical Half Hitch#1662 as worst security/nip warnings warning with Skull/Crossbones, but a base structure to build on.  Then shows the most security at top nip/opposing the linear load pull position as a safer Half Hitch form#1663 awarding Anchor icon if constant pull.    Then introduces Timber Hitch #1665 concept from extension of worst nip Half Hitch tail#1662 .  #1666 then shows Fig.8 concept  as upgrade to Half Hitch#1662 and shows the nip position pushed to halfway between normal and top nip Half Hitch.  Also adds a geometric consideration of:"particularly if the encompassed object is small." of even higher nip.   #1668 then shows the Fig.8 Timber Hitch with nip more to side and not bottom as improvement.<ref name="ashley290" />

Next trick is in #1669 Fig.8 Hitch with Round Turn.  Where the Round Turn is around the Standing Part and Fig.8 portion actually pictured as fig.8 Timber Hitch and so adds that  the "Round Turn on the Standing Part adds materially to the strength of the knot."<ref name="ashley290" />

Next chapter is "CHAPTER 22: HITCHES TO MASTS, RIGGING, AND CABLE (LENGTHWISE PULL)  To withstand a lengthwise pull without slipping is about the most that can be asked of a hitch. Great care must be exercised in tying the following series of knots, and the impossible must not be expected" that starts off with a Timber Hitch preceded by 'lengthwise' Half Hitch form to convert Timber from "RIGHT-ANGLE PULL" to "LENGTHWISE PULL" usage in the back to back chapters.<ref name="ashley290" />
