how did author and haris help in preparing iris stew

They attempt to make Irish stew, putting in potatoes without peeling them. Montmorency catches a water-rat and offers it to the men to add to the stew, but they decline. The stew turns out to be delicious. When the tea kettle shrieks, a frightened Montmorency attacks it. After dinner, George plays the banjo. A novice player, he is terrible at it. Montmorency howls along, and Harris and J. persuade George not to play for the remainder of the trip. J. mentions that George was later forced to sell the banjo because neither his landlady nor the passers-by outside his house can tolerate his playing.
