en he saw it was passing above them, aiming at some other target. A
second plane was following the first, a third was following the second.
There was a whole line of them, diving silently on some secret target.

The second he saw the planes, all question of the identity of the Ogrum
passed from Craig's mind. It was the Ogrum who flew those silent ships,
it was the Ogrum who had attacked the Idaho, who had sprayed the strange
acid on the sea that had damaged the ship. It was the Ogrum who now were
passing overhead intent on some other attack.

"Out of sight, everybody!" Craig shouted. The sailors slipped hastily to
cover. Craig joined them. Guru had already leaped back into the mouth of
his cave.

"What are those devils after this time?" Michaelson asked.

A second later, they had the answer.

Rolling across the swamps came the sound of a thunderous anti-aircraft
barrage from the Idaho.

The Ogrum were moving in to attack the warship, to deliver the last
smashing blow against the stranded battle wagon! Like vultures circling
a dying animal, they wheeled over the Idaho.

"Come on!" Craig said. "I don't know what we can do to help but we will
go and see."

As he hurried out of the ravine he saw Guru hastily helping his mate
carry the child to a higher, safer cave. Guru was hiding. The dawn man
might face a flying dragon, but the Ogrum were too much for him. Craig
did not blame him for hiding. He led his group hastily toward his boat.

Before they reached the place where they had left the small boat a crash
sounded behind them. Turning, they jerked up their guns. In this jungle
wilderness, anything might be attacking them. When they saw what was
following them, they dropped the muzzles of the weapons.

It was Guru. Waving his club, he had come to join them. He was
chattering excitedly.

"He says he has put his wife and little one where they will be safe,"
Michaelson translated. "He wants to know if we are going to fight the
Ogrum."

"Tell him yes," Craig answered.

"Then he says he wants to go along," the scientist interpreted.

For an instant Craig stared at the dawn man. Guru was scared. His fright
was obvious. Even thinking about the Ogrum scared him. But if his
new-found friends were going to fight the devils of the jungle, he was
going with them!

"There," said Craig appreciatively, "beats a fighting heart. Come on,
dawn man, you've got what it takes."
