Prendick uses his whip and revolver to convince the Beast Folk the Law still holds sway. Oh, and doing what Prendick says, that is also the Law.
He has the three Beast Folk bury Montgomery and his fellow party goers in the sea.
Hyena-Swine stumbles upon the scene. Prendick commands him to salute and bow, but Hyena-Swine asks, "Who are you, that I should…." (20.21). Prendick tries to show him, but the beast escapes into the forest.
Prendick realizes two things. First, the Beast Folk will now begin to change back into animals without Moreau. Second, they now understand that men with whips can be killed.
Prendick goes to the ravine. The Beast Folk give him food, and he falls asleep in one of their huts.
