is evidently the fairest and most desirable eternity that mortal man has the right to hope for.” “If, as you say, we cannot fight empty air, Tars Tarkas,” I replied, “neither, on the other hand, can empty air fight us. I, who have faced and conquered in my time thousands of sinewy warriors and tempered blades, shall not be turned back by wind; nor no more shall you, Thark.” “But unseen voices may emanate from unseen and unseeable creatures who wield invisible blades,” answered the green warrior. “Rot, Tars Tarkas,” I cried, “those voices come from beings as real as you or as I.

As it crept toward me it lashed its powerful tail against its yellow sides, and when it saw that it was discovered it emitted the terrifying roar which often freezes its prey into momentary paralysis in the instant that it makes its spring. And so it launched its great bulk toward me, but its mighty voice had held no paralysing
