This 1936 letter from Dean Nicholson to Mr. J. C. Poucher explains that he would not allow first class mail to be distributed to University of Minnesota students. The mail was sent by the Progressive Council, a student organization. Dean Nicholson stated that the group was not recognized by the University of Minnesota and could not use the U.S. postal service to deliver mail. This is an example of the ways that Dean Nicholson controlled student rights to distribute political information and to disrupt the United States Postal Service.
