"No use to walk when I can carry you, Mr. Swift," exclaimed Koku with a laugh. "I overtook you quite nice; so?"

"Yes, you took me over in great shape, Koku!" replied the aged inventor with a smile at Koku's English, for the giant frequently got his words backwards. "That barrow is quite heavy for me to wheel."

"You after this call me," suggested Koku.

"Say, but he's strong all right," exclaimed Ned, "and that was an awkward thing to carry."

"It sure was," agreed Tom. "I haven't yet seen any one strong enough to match Koku. And he's gentle about it, too. He's very fond of dad."

"And you too, I guess," added Ned.

"Well, Koku, did you get that attachment?" asked Tom, as his giant servant entered the room.

"Yes, Mr. Tom. I have it here," and from his pocket Koku drew a heavy piece of steel that would have taxed the strength of either of the boys to lift with one hand. But Koku's pockets were very large and made specially strong of leather, for he was continually putting odd things in them.

Koku handed over the attachment, for which his master had sent him. He held it out on a couple of fingers, as one might a penknife, but Tom took both hands to set it on the ground.

"I the female get, also," went on Koku, as he began taking some letters and papers from his pocket. "I stop in the office post, and the female get."
