“Come, and you will be kings among the small men in our country,” invited Poddington.  The brothers looked at each other, talked together in low tones, and then Koku exclaimed: 

“We will come, and we will help you to escape.  We have spoken, and we will talk with you again.”

Then they glided out into the darkness, while from afar came the sounds of revelry at the big feast.

CHAPTER XXIII

A SURPRISE IN THE NIGHT

Tom and his friends could scarcely believe their good fortune.  It seemed incredible that they should have induced two of the biggest giants to accompany them back, and, not only that, but that they had the promise of the strong men to aid them.

“Now we must get busy,” declared Tom, when their visitors had gone.  “We’ve got lots of work to do on the aeroplane, and we must try out the engine.  Then we’ve got to fix the side of the hut so it will fall out when we’re ready for it.  And we’ve got to plan how to meet the giants later in the forest.”

“Yes,” agreed the circus man, “and we must take care that Hank Delby doesn’t spoil our plans.”

Then ensued busy days.  In the seclusion of their hut the prisoners could work undisturbed at the aeroplane, which had been almost assembled.

The engine was installed and tried, and, when the motor began its thundering explosions, there was consternation among the giants, who had again surrounded the hut to see that the prisoners did not escape.

Meanwhile Delby seemed to be unusually active.  He could be observed going in and out from his hut to that of the king, and he often carried large bundles.

“He’s making himself solid with his royal highness,” declared Tom.  “Well, if all goes right, we won’t have to worry much longer about what he does.”

“If only those twin giants don’t fail us,” put in Ned.

“Oh, you can depend on them,” said Mr. Poddington.  “These giants are curious creatures, but once they give their word they stick to it.”

He told much about the strange big men, confirming Tom’s theory that favorable natural conditions, for a number of generations, had caused ordinary South American natives to develope into such large specimens.

Our friends were under quite a nervous tension, for they could not be sure of what would happen from day to day.  They continued to work on the aeroplane, and then, finding that it would work in the seclusion of the hut, they were anxious for the time to come when they could try it in the open.

“Do you think it will carry the five of us with safety?” asked the circus man, as he gazed rather dubiously at the somewhat frail-appearing affair.

“Sure!” exclaimed Tom.  “We’ll get away all right if I can get enough of a start.  Now we must see to opening the side of the hut.”

This work had to be done cautiously, yet the prisoners had a certain freedom, for the guards were afraid to approach too closely.
