When an uncle who does not even play upon an old second-hand horn wishes to get rid of that horn, and even complains of having it on his hands, it seems reasonable to consider that the horn becomes the property of a nephew who has gone to the trouble of carrying the undesired thing out of the house.
Penrod determined to deal fairly.

The difference between this horn and the one in the "music-store" window seemed to him just about the difference between two and eighty-five.

He drew forth the green bill from his pocket.
"Roddy," he said, "I'll give you two dollars for that horn." Sam Williams's mouth fell open; he was silenced indeed.

But for a moment, the confused and badgered Roddy was incredulous; he had not dreamed that Penrod possessed such a sum.
"Lemme take a look at that money!" he said.
If at first there had been in Roddy's mind a little doubt about his present rights of ownership, he had talked himself out of it.

Also, his financial supplies for the month were cut off, on account of the careless dog.
