The Bobbsey Twins’ Adventure in the Country was published in 1907 and is the second book in the original series, following directly from the first volume. The family travels to spend an extended summer at the country home of relatives, in this case Uncle Daniel and Aunt Sarah Bobbsey at Meadow Brook Farm. The setting allows the series to do its earliest rural-adventure plotting.
The twins encounter farm life for the first time. Bert helps with the haying. Nan learns to milk a cow. Flossie and Freddie befriend a calf named Bossy. There is a mild mystery involving a stranger who has been seen lurking in the woods at the edge of the farm, eventually identified as a harmless surveyor doing legitimate work. The book is gentler and shorter than later entries in the series. The cousin family at Meadow Brook would become recurring fixtures in later books, with their farm appearing as a setting in several subsequent novels.
