Settlers found the land generally level and suited for farming. Chief crops were corn, potatoes and hay. Buxton also provided excellent water power sites. The first sawmill was on the Little River, a tributary of the Presumpscot River. A gristmill called Bog Mill was built at the outlet of Bonny Eagle Pond. The biggest mills, however, were located at the series of falls on the Saco River. Salmon Falls had sawmills capable of turning out four million feet of lumber annually. Bar Mills had gristmills and a box mill. Moderation Falls in West Buxton had sawmills, heading mills and woolen textile mills which produced about 936,000 yards of cloth annually. Buxton's mill town prosperity left behind fine architecture. Listed on the National Register of Historic Places are Elden's Store, the Buxton Powder House, the First Congregational Church, Royal Brewster House and Salmon Falls (East) Historic District.
