"Hold on, dere!" yelled Eradicate again.

Then a voice replied:

"Bless my insurance policy! What's the matter? Have there been burglars around? Why all these precautions? Bless my steam heater! Don't you know me?"

"Mr. Damon!" cried Tom, a look of pleasure coming over his face. "Mr. Damon is coming!"

"So I should judge," responded Mr. Swift, with a smile. "I wonder why Eradicate didn't recognize him?"

They learned why a moment later, for on looking from the library window, Tom saw the colored man coming up the walk behind a well-dressed gentleman.

"Why, mah goodness! It's Mr. Damon!" exclaimed Eradicate. "I didn't know yo', sah, wif dem whiskers on! I didn't, fo' a fac'!"

"Bless my razor! I suppose it does make a difference," said the eccentric man. "Yes, my wife thought I'd look better, and more sedate, with a beard, so I grew one to please her. But I don't like it. A beard is too warm this kind of weather; eh, Tom?" And Mr. Damon waved his hand to the young inventor and his father, who stood in the low windows of the library. "Entirely too warm, bless my finger-nails, yes!"

"I agree with you!" exclaimed Tom. "Come in! We're glad to see you!"

"I called to see if you aren't going on another trip to the North Pole, or somewhere in the Arctic regions," went on Mr. Damon.
