Having been so recently moved, this dirt was easy to dig.
Yet, suddenly, there came a new note on the night air.
"Jack, O Jack!" sounded in Hal's frantic tones. "Quick!"
"Eh?" called Captain Benson. "What's the row? Come here and see what I can show you!"
"No! You come here—quick!"
"That's queer," pondered Jack Benson, leaning on his shovel, trying to understand what it could all mean.
Then he heard, even at the distance, the sound of Hal Hastings panting, as though engaged in hard physical effort.
Again rose Hastings's frantic voice, though somewhat muffled in its sound.
"If you don't hustle, it will be too late!"
Jack dropped the shovel on the ground, wheeled, and ran down the slope to where Hal's voice sounded.
