When Rad set his eyes on the gigantic Koku he cried out:

“Ma goodness, Mars’ Tom! couldn’t you lose dat big nuisance up da in de Antic Seas somewhar? He suah ain’t much good ’round yere. I reckoned he’d make good polar bear bait, or de like. Has I got to feed him again?”

Koku showed his teeth in a wide smile. “No polum bear kill Koku,” he declared, leaping out of the flying boat and beginning to strut. “Koku kill bear. Killum with spear. Koku great chief.”

“Koku great nuisance,” grumbled Rad, grabbing the big fellow by the arm. “Come on wid me. I got a beefsteak ha’f as big as a bedsheet to brile for yo’. Yo’ suah isn’t much good, but we got to feed yo’.”

Mr. Nestor was welcomed by his wife and daughter almost as though he had risen from the grave. His improvement in health was so great that they could not cease exclaiming over it.

Tom and his other friends from the flying boat were all greeted most hilariously by the crowd. The mechanicians and Kingston had their stories to tell. Ned hurried away on business. Mr. Barton Swift wrung his son’s hand.

“I was afraid for a while that that strange Russian would manage to make you trouble. Admiral Gilder found out about him soon after you had started on your cruise. The fellow had got credentials from the Navy Board by trickery.”

“If the Soviet Government had had a bunch of flying men up there at Reykjavik, ready to hop aboard the craft when they got us out and under guard,” said Tom, “they might have managed to get the Winged Arrow as far as Russia, and we would have whistled for any money. Their printing presses could not print rubles fast enough to pay me for this flying boat.”

“Then you consider her a success, Tom?” asked Mr. Swift smiling.

“She most certainly is. As far as I have gone I am satisfied. But I have not finished with her yet. You wait and see, Dad.”
