“Yes.”
“Well, that was not there yesterday.”
“Eh?”
“It is true!”
Even as he spoke, Randall gave an exclamation. He pointed to a patch of turf near, and whispered:
“Look—look! You cannot want better evidence.”
Frank gazed in the direction indicated, and both beheld a most astounding thing.
The little patch of turf had begun to throb and heave. Soon dew-like moisture was seen on the blades.
Then up shot a little bulb of boiling water. It momentarily grew larger.
The turf was gently thrust aside and disintegrated, while a tiny stream flowed away down the incline, making its own course and momentarily growing larger.
