Retreating through the passage he reached the room where he had been chained and wrenched the iron post from its socket.

It was a foot thick and four feet long, and being of solid iron was so heavy that three ordinary men would have found it hard to lift.
Returning to the cavern, the boy swung the great bar above his head and dashed it with mighty force full at the giant.

The end of the bar struck the monster upon its forehead, and with a single groan it fell full length upon the floor and lay still.
When the giant fell, the glow from its eyes faded away, and all was dark.

Cautiously, for Inga was not sure the giant was dead, the boy felt his way toward the opening that led to the middle cavern.

The entrance was narrow and the darkness was intense, but, feeling braver now, the boy stepped boldly forward.
