The opening appeared to be a split in the mountain, perhaps made ages before by volcanic action. I felt certain there was an opening above, for in several spots the rain came down, forming small pools and streams of water.
Suddenly the idea struck me to watch which way the water ran, and I did so and learned that its course was in the very direction I was walking. Moreover the tiny streams merged one into another, until, several hundred feet further on, they formed quite a water course.
“If only this stream flows into the main river!” I thought, and on the spur of the moment resolved to follow it as far as I was able, satisfied that if it led to nowhere in particular I could retrace my steps to its source.
I now found the cave growing narrower, and presently it grew less than a dozen feet in width, and the stream covered the entire bottom to the depth of several inches. Throwing my boots over my shoulders, I began wading, feeling sure of one step ere I trusted myself to take another.
It took me fully ten minutes to proceed a hundred feet in this fashion. The stream was now not over six feet wide and all of a foot deep.
Making sure that my torch was in no danger of going out, I continued to advance, but now more slowly than ever, for in the distance I could hear the water as it fell over a number of rocks. There was a bend ahead; and this passed, I fervently hoped to emerge into the open air, on the opposite side of the mountain and close to the bank of the river for which I was seeking.
At the bend the water deepened to my knees, and I paused to roll up my trousers, in the meantime resting the torch against the wall, which afforded a convenient slope for that purpose.
I had just finished arranging my trouser-legs to my satisfaction, when a rumble of thunder, echoing and re-echoing throughout the cavern, made me jump. My movement caused the cedar branch to roll from the rocks, and it slipped with a hiss into the stream. I made a frantic clutch for it, and, in my eagerness to save it from going out or getting too wet, I fell on it in the very middle of the stream.
With a splutter I arose to find myself in utter darkness. Moreover, the cedar branch was thoroughly soaked, and it would take a good many matches to light it again. And what was still worse, every match my pocket contained was soaked as badly as the torch.
