He seemed searching for a rhyme.

"Pagoda! Pagoda!" laughed Betty.

"That is it!" exclaimed Mr Lagg. "Thank you for the suggestion. Let me
see, now. How would this do?

"If you wish to drink of Lagg's fine soda,
Just take your seat in a Chinese pagoda!"

"Very good," complimented Will. "We'll dispense with the pagoda if you
will dispense the soda."

"Ha! Good again! You are a punster, I see!"

Mr. Lagg laughed genially, and soon provided the party with bottles of
deliciously cool soda, and straws through which to partake of it,
glasses being voted too prosaic.

There came a protest from Paul, who was sharing the treat.

"I tan't dit no sody!" he cried. "It all bubbles up!"

"No wonder! You are blowing down your straw. Pull up on it, just as if
you were whistling backwards," said Mollie.

"Whistling backwards is a distinctly new way of expressing it,"
commented Frank.
