Beales Mill began in the 1860’s when Benjamin Beale settled in an area of Leeds County approximately 1.5 kilometres from Charleston. Bales began construction of a home and a mill alongside a creek that would take on his name.

Over time, Beales Mill added a grist-mill and flower mill and went into shingle production. The mills were kept busy with area farmers, many of whom had arrived from south of the border. Situated beside a waterfall, the mills had ample water for mill power while Charleston did not.

Mail delivery for Beales Mill was likely serviced out of Charleston as Beales Mill did not have their own post office. The mills continued operation into the early 20th century. Charleston contained two hotels, a blacksmith, cooper and the Slack & Foster sawmill.

The remains of the mill can be found along the waterfalls. Look for Beales Mill Road off of County Road 5.
