"I wouldn't give sixty-five cents for his whole outfit," declared Ned.
"Perhaps that is because you haven't sixty-five cents," retorted Tad.

"A post office?" cried the lads.
"Yes. I thought perhaps you might wish to send off some letters."
"Yes, we do. Indeed, we do," cried Ned and Tad and Walter in chorus.

"I suppose you can get all you want in here, provided you have the money to pay for it," smiled Professor Zepplin.
