In the early 1850s Father Boniface Wimmer began planning for the construction of a gristmill at Saint Vincent. He commissioned a local millwright, George Washington Bollinger, to design the gristmill, for which he received the salary of $400. Two sets of buhrstones were purchased from a flint quarry in France. These buhrstones were shipped to Saint Vincent in anticipation of the gristmill being built so that they could be put to use. Boniface Wimmer sent one of the lay brothers, Brother Peter Seemueller, to a local miller “in order to learn first hand the grinding mechanism.” as Wimmer stated in a letter dated July 29, 1853.
