Injun Joe's bowie-knife lay close by, its blade broken in two. The great foundation-beam of the door had been chipped and hacked through, with tedious labor; useless labor, too, it was, for the native rock formed a sill outside it, and upon that stubborn material the knife had wrought no effect; the only damage done was to the knife itself. But if there had been no stony obstruction there the labor would have been useless still, for if the beam had been wholly cut away Injun Joe could not have squeezed his body under the door, and he knew it. So he had only hacked that place in order to be doing something--in order to pass the weary time--in order to employ his tortured faculties. Ordinarily one could find half a dozen bits of candle stuck around in the crevices of this vestibule, left there by tourists; but there were none now. The prisoner had searched them out and eaten them. He had also contrived to catch a few bats, and these, also, he had eaten, leaving only their claws. The poor unfortunate had starved to death. In one place, near at hand, a stalagmite had been slowly growing up from the ground for ages, builded by the water-drip from a stalactite overhead. The captive had broken off the stalagmite, and upon the stump had placed a stone, wherein he had scooped a shallow hollow to catch the precious drop that fell once in every three minutes with the dreary regularity of a clock-tick--a dessertspoonful once in four and twenty hours. That drop was falling when the Pyramids were new; when Troy fell; when the foundations of Rome were laid; when Christ was crucified; when the Conqueror created the British empire; when Columbus sailed; when the massacre at Lexington was "news."

     It is falling now; it will still be falling when all these things shall have sunk down the afternoon of history, and the twilight of tradition, and been swallowed up in the thick night of oblivion. Has everything a purpose and a mission? Did this drop fall patiently during five thousand years to be ready for this flitting human insect's need? and has it another important object to accomplish ten thousand years to come? No matter. It is many and many a year since the hapless half-breed scooped out the stone to catch the priceless drops, but to this day the tourist stares longest at that pathetic stone and that slow-dropping water when he comes to see the wonders of McDougal's cave. Injun Joe's cup stands first in the list of the cavern's marvels; even "Aladdin's Palace" cannot rival it.
