"Guess I'll go, too," added Sam, and quickly followed. Soon Dick came also, not wishing to be left behind if anything unusual was to take place.

In the lower hallway the boys found several men at work, cleaning and oiling the hardwood floor. They had a box of wax polish with them, and this immediately gave Tom an idea.

"I'd like to buy a little of that," he said, to the head workman, and a bargain was quickly struck, and the fun-loving Rover walked away with half a box of the wax polish.

"What are you going to do with it?" asked Sam.

"Don't know yet—but I'll do something," was the reply.

"Looks like maple sugar candy," said Dick, gazing at the wax.

"Wait! I've struck it!" cried Tom. "Just the thing! Hurray!" And his face brightened.

"What is it, Tom?" asked both of his brothers.

"I'll make William Philander Tubbs a present of this," was the reply. "Come on, and watch how I do it."

"William Philander has gone to see that new, girl of his," answered Sam.
