“What are we going to do?” asked Ned, who was beginning to lose heart when he saw the increasing crowd of savages and realized that the airship was disabled.

“Do?” cried Tom. “Why, we’re going to carry on, of course! It will not take long to attach a new propeller, and we’ll have to fight off these imps while it’s being done. Hartman and Brinkley can do the work, while you and I, Ned, with Peltok, will stand guard.”

This program was carried out, though under great difficulties. The head-hunters, in spite of their heavy losses, returned to the attack soon after the two machinists began attaching the spare propeller. The old one had lost a blade, possibly through some defect in it, Tom decided.

Ned and Peltok worked the machine gun at the stern, thus protecting Hartman and Brinkley from an overwhelming rush, while Tom, with several magazine rifles ready to hand, peppered the natives who sought to come at the craft from the front.

In this way the fight and repair work went on for a couple of hours, until, at last, the execution among the head-hunters was so great that they were forced to withdraw. Ned received another slight scratch from an arrow, but there were no other casualties on board the Air Monarch, which was rapidly being put in shape for another flight.

It was not until late in the afternoon, however, and following a most strenuous hour, that the machinists announced that the propeller was in place.

“And it’s about time, too,” said Tom. “I think the head-hunters are going to make another grand rush.”

This was plainly evident from the additional canoes that were being filled with islanders who swarmed down to the shore. They seemed determined, no matter how severe their own losses, to get the heads of these strangers.

Peltok tried to listen to the shouted talk of the savages, but had to admit that they spoke a dialect unfamiliar to him. However, it was evident that the yells and shouts had to do with the intentions of the war party.

“Here they come!” yelled Ned, when word had been given to start the motors. “Wow, what a mob!”
