List some of the topics of conversation at the rainbow inn.

At the Rainbow tavern, while the personages of Raveloe attend Mrs. Osgood's dance, some of the less lofty villagers drink and talk. Among these is the landlord, Mr. Snell, whose outlook on most matters is neutral, and whose position in most arguments is that of a mediator, befitting one who needs to sell drinks to men of all walks of life. The skeptical farrier, Mr. Dowlas, cannot enter a conversation without contradicting somebody. Mr. Ben Winthrop, a large and jolly wheelwright who leads the church choir on Sundays, and Mr. Macey, an old man who is full of anecdotes of a Raveloe now mostly past, are two of the other principals in a series of arguments and stories.
