What happened when George tried to learn playing the Banjo?

Harris would get angry and the dog would howl,

"He tried on two or three evenings, while we were up the river, to get a little practice, but it was never a success. Harris’s language used to be enough to unnerve any man; added to which, Montmorency would sit and howl steadily, right through the performance. It was not giving the man a fair chance."

People claimed his playing might harm children. He also tried practicing in the town square but it did not go well,

"Then George tried taking it out with him late at night, and practising round the square. But the inhabitants complained to the police about it, and a watch was set for him one night, and he was captured. The evidence against him was very clear, and he was bound over to keep the peace for six months."
