"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."

With Guru to lead them and point out passages through the swamp, they made speedy time in the boat. Meanwhile, clearly audible but out of sight, the sky was filled with the thunder of guns.

"The ack-ack will knock those planes out of the sky," one of the sailors said.

"I wish I thought so," Craig answered.

"What do you mean?" Michaelson questioned.

"The Ogrum must know we have anti-aircraft defenses," the big man said uneasily. "We shot one of their planes down when they attacked our scouting flier. They know we can and will fight. If they attack us under those circumstances, it means one of two things—either they're crazy or they think they can take us in spite of our ack-ack. For all I know, they may be crazy, but I'm betting they think they can take us. Sh—" Craig listened.

The anti-aircraft barrage was thinning out. The guns were not firing as furiously as they had at first. Uneasiness showing on their faces, the sailors listened.
