"I know! I know what we can do! He can't be persuaded out or dragged out, but he can be driven out."

"How?" asked Uncle Tom.

"If you'll come with me," replied the boy, "I'll show you in two minutes."

So saying, he jumped across the creek and set off straight up the almost perpendicular side of the mountain, we two following. Uncle Tom, however, finding the climb too steep for him, very soon turned back again, so we two boys went on alone.

About three hundred feet up my companion stopped, and it was well for me he did, for I could hardly have gone another step, so desperately out of breath was I.

"Not used to it, are you?" said the boy, who himself seemed to be quite unaffected. "Well, we don't have to go any higher, fortunately. Look over there. Do you see that stubby pine tree growing out of the rocks and overhanging the waterfall?"

"Yes, I see it," I replied. "And what's that big round thing hanging to it?"

"A wasps' nest."

"A wasps' nest?"

"A wasps' nest," repeated my new acquaintance with peculiar emphasis and with a twinkle in his eye.
