The Lion tribe will be seen tearing open the earth with their clawed paws and in the caves thus made, burying themselves together with the other animals that are beneath them.
Animals will come forth from the earth in gloomy vesture, which will attack the human species with astonishing assaults, and which by their ferocious bites will make confusion of blood among those they devour.
Again the air will be filled with a mischievous winged race which will assail men and beasts and feed upon them with much noise— filling themselves with scarlet blood.
