Learn now the lore of Living Creatures!
First name the four, the free peoples:
Eldest of all, the elf-children;
Dwarf the delver, dark are his houses;
Ent the earthborn, old as mountains;
Man the mortal, master of horses...

Beaver the builder, buck the leaper,
Bear bee-hunter, boar the fighter;
Hound is hungry, hare is fearful...

Eagle in eyrie, ox in pasture,
Hart horn-crownéd; hawk is swiftest,
Swan the whitest, serpent coldest...

Half-grown hobbits, the hole-dwellers.
