What two friendships does Jerry develop at the cabin?
A Mother in Mannville by Marjorie Kinnan Rawlings is a story of a narrator who rents a cabin in the Carolina mountains to write in peace and quiet; she also appears to be native to the region and homesick. The cabin is owned by an orphanage and one of the orphans, a 12-year old boy Jerry, is sent to help the narrator with chopping wood and other tasks. The narrator is impressed by a quality of integrity in the boy. As the boy continues to visit the narrator, he gradually becomes acquainted with her dog Pat, a pointer. When the narrator is stranded away from the cabin due to the fog making driving back impossible, Jerry takes care of the dog, with whom he has bonded.
The narrator is the first friend made by Jerry at the cabin. The second friend is the dog.
