“Yas, sah, Massa Tom!”

“Me git my own ladder—­dat one not strong ’nuff!” grunted Koku, who did not speak very good English.  He had a very strong ladder, of his own make, built to hold his enormous bulk, and this he soon brought and placed against the side of the house.

Meanwhile Tom and his father had raised the one Eradicate had brought, though Tom did most of the lifting, for his father was elderly, and had once suffered from heart trouble.

“We’re coming for you!” cried the young inventor as he began to ascend the ladder, at the same time observing that the giant was coming with his.  “Can you hold on a little longer?”

“Yes, I guess so.  But I dare not move for fear the propellers will strike me.”

“I see.  I’ll soon shut off the motor,” said Tom.  “What happened, anyhow?”

“Well, I was flying over your house.  I was on my way to pay you a visit, but I didn’t intend to do it in just this way,” and the birdman smiled grimly.  “I didn’t see your wireless aerials until I was plumb into them, and then it was too late.  I hope I haven’t damaged them any.”

“Oh, they are easily fixed,” said Tom.  “I hope you and your biplane are not damaged.  This way, Koku!” he called to the giant.

“Say, is—­is he real, or am I seeing things?” asked the aviator, as he looked at the big man.

“Oh, he’s real, all right,” laughed Tom.  “Now, then, I’m going to shut off your motor, and then you can quit hugging that chimney, and come down.”

“I’ll be real glad to,” said the birdman.

Making his way cautiously along the gutters of the roof, Tom managed to reach the motor controls.  He pulled out the electrical switch, and with a sort of cough and groan the motor stopped.  The big propellers ceased revolving, and the aviator could leave his perch in safety.

This he did, edging along until he could climb down and meet Tom, who stood near the ladder.

“Much obliged,” said the birdman, as he shook hands with Tom.  “My name is Grant Halling.  I’m a newcomer in Mansburg,” he added, naming a town not far from Shopton.  “I know you by reputation, so you don’t need to introduce yourself.”

“Glad to meet you,” said the young inventor, cordially.  “Rather a queer place to meet a friend,” he went on with a laugh and a glance down to the ground.  “Can you climb?”

“Oh, yes, I’m used to that.  The next thing will be to get my machine down.”

“Oh, we can manage that with Koku’s help,” spoke Tom.  “Koku, get some ropes, and see what you and Rad can do toward getting the aeroplane down,” he added to the giant.  “Let me know if you need any help.”

“Me can do!” exclaimed the big man.  “Me fix him!”

Tom and Mr. Halling made their way down the ladder, while the giant proceeded to study out a plan for getting the airship off the roof.

“You say you were coming over to see me, when you ran into my wireless aerials?” asked Tom, curiously, when he had introduced his father to the birdman.
