“No, he won’t object. Though he relies on our doing a good day’s work without supervision, he relies, too, on our using our common sense, and I’m sure he’ll agree that this is a matter that ought to be investigated without delay. It may be of the greatest importance.”

“All right!” cried Joe. “Then let us get about it at once!”


CHAPTER IX

The Underground Stream

It was on a Saturday morning that we made this discovery, and as my father and mother had both driven down to San Remo and would not be back till sunset, we could not ask permission to abandon our regular work and go exploring. But, as I had said to Joe, though he trusted us to work faithfully at any task we might undertake, my father also expected us to use our own discretion in any matter which might turn up when he was not at hand to advise with us.

I had, therefore, no hesitation in driving back to the ranch, when, having unloaded our one stone and stabled the mules, Joe and I, taking with us a long, stout rope and the stable-lantern, retraced our steps to the wildcat’s house.

The first thing to be done was to enlarge the entrance so that we might have daylight to work by, and this being accomplished, we lighted the lantern and lowered it by a cord into the hole. We found, however, that a bulge in the rock prevented our seeing to the bottom, and all we gained by this move was to ascertain that the crevice was about forty feet deep, as we had guessed. The next thing, therefore, was for one of us to go down, and the only way to do this was to slide down a rope.

This, doubtless, would be easy enough, but the climbing up again might be another matter. We were not afraid to venture on this score, however, for, as it happened, we had both often amused ourselves by climbing a rope hung from one of the rafters in the hay-barn, and though that was a climb of only twenty feet, we had done it so often and so easily that we did not question our ability to ascend a rope of double the length.
