"She certainly is a success," agreed Ned. "You could creep up on
some other airship now, and those aboard would never know you were
coming."

"I've been planning this for a long time," went on our hero, as he
shifted the steering gear, and sent the craft around in a long,
sweeping curve. "Now for Waterford and Mr. Damon."

They were soon above the town where the odd man lived, and Tom,
picking out Mr. Damon's house, situated as it was in the midst of
extensive grounds, headed for it.

"There he is, walking through the garden," exclaimed Ned, pointing
to their friend down below. "He hasn't heard us, as he would have
done if we had come in any other machine."

"That's so!" exclaimed Tom. "I'm going to give him a sensation. I'll
fly right over his head, and he won't know it until he sees us. I'll
come up from behind."

A moment later he put this little trick into execution. Along swept
the airship, until, with a rush, it passed right over Mr. Damon's
head. He never heard it. and was not aware of what was happening
until he saw the shadow it cast. Then, jumping aside, as if he
thought something was about to fall on him, he cried:

"Bless my mosquito netting! What in the world--"

Then he saw Tom and Ned in the airship, which came gently to earth a
few yards further on.
