The first one, standing on the floor of the crevice, reached as high as the ledge Joe had mentioned, while the second, planted upon the ledge itself, leaned across the chasm, its upper end resting against the rock just below the bulge, so that, with the rope to hold on by, it ought to be easy enough to get up and down. It is true that the second ladder being almost perpendicular, looked a little precarious, but we had taken great care to set it up solidly and were certain it could not slip. As to the strength of the ladders, there was nothing to fear on that score, for the smallest of the poles was five inches in diameter at the little end.

This work took us so long, for we were very careful to make things strong and firm, that it was within half an hour of sunset ere we had finished, and as it was then too late to begin hauling rocks, we drove down to the ranch again at once.

As we came within sight of the house, we had the pleasure of seeing the buggy with my father and mother in it draw up at the door. Observing us coming, they waited for us, when, the moment we jumped out of the wagon, before we could say a word ourselves, my father exclaimed:

“Hallo, boys! What are you wearing your rubber boots for?”

My mother, however, looking at our faces instead of at our feet, with that quickness of vision most mothers of boys seem to possess, saw at once that something unusual had occurred.

“What’s happened, Phil?” she asked.

“We’ve made a discovery,” I replied, “and we want father to come and see it.”

“Can’t I come, too?” she inquired, smiling at my eagerness.

“I’m afraid not,” I answered. “I wish you could, but I’m afraid your petticoats would get in the way.”
