Ray H. Mattison thanks Roy P. Johnson for his hard work gathering and sending him research materials regarding the authenticity of Theodore Roosevelt’s Maltese Cross cabin. The information Mattison has gathered from interviewing old timers backs the authenticity of the cabin thus far, although he still has more people to interview. Mattison believes Hermann Hagedorn is incorrect in saying that Roosevelt went to Red River country in Nebraska in 1882, because there is Red River in Nebraska. He notes a paragraph in Roosevelt’s 1920 autobiography in which the President talks about his first trip to Fargo, North Dakota in 1883, not 1882.
