for they had now seen enough to convince them that the
Prince was really protected by some invisible power.

As they came before the gates another shower of
arrows and spears descended upon them, and as before
not a single missile touched their bodies. King Gos,
who was upon the wall, was greatly amazed and somewhat
worried, but he depended upon the strength of his gates
and commanded his men to continue shooting until all
their weapons were gone.

Inga let them shoot as much as they wished, while he
stood before the great gates and examined them
carefully.

"Perhaps Bilbil can batter down the gates, suggested
Rinkitink.

"No," replied the goat; "my head is hard, but not
harder than iron."

"Then," returned the King, "let us stay outside;
especially as we can't get in."

But Inga was not at all sure they could not get in.
The gates opened inward, and three heavy bars were held
in place by means of stout staples riveted to the
sheets of steel. The boy had been told that the power
of the Blue Pearl would enable him to accomplish any
feat of strength, and he believed that this was true.
