Rural school attended by Hagen Siblings

This is the school that our parents attended. It stood northwest of our house about a fourth of a mile, along the road going to the church. It was torn down sometime ago. I do remember that the indians ( Native Americans) that worked for dad lived in the school during the summer months. Marilyn is older so maybe she can recall more details about the school. I know that dad has told me who is in the picture but I have forgotten. I know that the tallest person has to be a Holgerson. Notice the outhouse. Dad told us that he and Conrad Holgerson ran a stick through an opening in the back of the toilet and tickled the teachers bottom as she was going potty. The teacher was living with Grandma and Grandpa at the time . Dad said that he thought they were amused by their antics but it was a punishable offense!
