The Outdoor Girls in a Winter Camp

Mr. Ford must have someone stay at his lumber camp in the North Woods in order to prevent the theft of lumber. It is decided that Grace and her friends will stay in the camp until Mr. Ford is able to travel north. Complications develop when Alice Jallow's family claims to own some of the Ford land.
Upon the girls' arrival, they discover that Alice and her family are staying on the adjoining Jallow property and have placed a guard on the disputed land. This development is most unpleasant for Amy, who has repeatedly been the victim of Alice's unkind remarks about her past.
