Monthly publication of the Journal was finally an achievable objective. At long last, the Association acted to recog¬ nize those Members who had been outstanding contributors over the years through an awards program. Awards were presented to recognize a Sanitarian for their service to the profession and a Citation Award was given to honor a Member's service to the Association. The 39th Annual Meeting set a record for registration, 486, including 53 women. Revisions to the Constitution and Bylaws were passed at the 1953 Annual Meeting. It was decided that the Officers of the Association would be President, President-Elect, First Vice- President, Second Vice-President, and Secretary- Harold Wainess displays a bulk milk dispensing machine.
