Senior members stood facing the camera while underclassmen faced away from the camera with various and sundry items placed over their heads. The US and UP were the precursor of the modern Purple Poo . The still-secret organization makes Poo signs each Monday night, which then appear on campus every Tuesday morning. The signs comment on campus political life, student life, but mostly on school spirit. These signs are nailed to trees on campus.
Members appear in public dressed in costumes, and their identity is closely guarded.
The symbol of the Plowboys was a muscular young man in overalls pushing a hand plow. In 1950, the mascot withstood a challenge when four additional names were suggested for a student vote. Plowboys won by a 2-1 margin. The horse and rider became the new logo of the University. The Plowboys attend athletic events and other campus activities and are familiar to students because of their white shirts, hats, and purple chaps.
