The book The Sign of the Beaver takes place around 1768. In the book the boy, Matt, states that his father and family had worked out a plan in 1768. Matt's father had purchased some land in Maine and Matt and his father had traveled there to build a cabin and start a homestead. Once the homestead was finished, Matt's father went back to get the rest of the family leaving Matt behind to protect their new home.
The two had built a log house. The house had temporary fixtures in the window and a clay lined fireplace. Matt's father was supposed to be gone for six weeks.
