[1] In this volume in the series, horseless carriages arrive in Deep Valley for the first time when Mr. Poppy, the owner of the Opera House, buys an automobile.

Betsy befriends the lonely Mrs. Poppy, who welcomes the chance to share the little girls' affection after having lost her only daughter in the years before moving to town.

Betsy's parents decide that in order to foster a love of classic literature and make Betsy a better writer, she will be allowed to go alone to the new Carnegie library every two weeks, with spending money for a special mid-day treat to let her stay all day.
