In 1669 he was succeeded by Father Jacques Marquette (q.v.) and went to the Fox River Valley; there he established the mission of St Francis Xavier at the first rapids' on the Fox river near a populous Indian village.
The Fox river furnishes about 10,000 h.p., which is largely utilized for the manufacture of paper (of which Appleton is one of the largest producers in the United States), wood-pulp, sulphite fibre, machinery, wire screens, woollen goods, knit goods, furniture, dyes and flour.
Appleton was one of the first cities in the United States to have an electric street railway line in operation; and electric street railways now traverse the entire Fox river valley as far as Fond du Lac on the south and Green Bay on the north.
Along the shore of Lake Michigan, and extending inland a quarter of the distance across the state and northward through the Fox River Valley, there was a heavy belt of oak, maple, birch, ash, hickory, elm and some pine.
Dams on the Fox River furnish a good water-power.
The eastern elevation is a ridge or cuesta formed by an outcropping hard layer of the ancient coastal plain; and it separates the Wisconsin river basin from the Fox River Valley and the streams flowing into Lake Michigan.
