Section F, the twelve chapters from 65, "A discourse on the suburban sacrifice," to 76, "The significance of sacrifices," discusses sacrificial services. Most of the first half of this section is devoted to discussion of the suburban sacrifice, but the texts are in bad shape and the damage seems to be very early. Other topics covered include the four seasonal sacrifices and the starting and stopping of rain (chapters 74 and 75). There is also Chapter 73, the "Praise-ode to mountains and rivers," which can be confidently dated to the last few decades of Former Han at the latest.
