At the one room school, in 1953, I realized we had a mouse (or two) in the storage closet. So the next day I brought a trap. As soon as the children quieted down, and I was in the middle of first grade reading class. SNAP I sent one of the eight grade boys to take it outside and reset the trap. We went back to class. SNAP Got the second one. I think we got one more later in the day, and then no more.
