In 1825 the population was estimated to be 6,000. By the treaties of 1825 and 1832 they were compelled to cede their lands to the government, certain tracts of land being reserved on the Mississippi river near what is now known as La Crosse. Here they suffered from several visitations of smallpox, which plague is said to have carried off nearly one-fourth of their number. From 1834-35 they were removed to Iowa and lived along the many rivers in the northeastern part of the Territory as far as the banks of the Cedar and the Wapsie rivers. White settlers came in, driving the Red Men out: hunting became poor and the Indians could not subsist and they were again removed to the Blue Earth reservation in Minnesota in 1848. On account of the Indian outbreaks in 1863, committed by the Sioux tribe, and in which the Winnebagoes took no part, they were again removed to the Dakotas, where several hundred perished from cold and hunger. There are now only about 1,200 under the Omaha and Winnebago agency in Nebraska, and about 1,500 in the state of Wisconsin. The Sac and Fox were also the early neighbors of the whites in this county. The Fox was an Algonkian tribe, first found on the lakes, and who were driven south by the Ojibwa where, for self protection, they united with the Sacs and have been since known as Sacs and Foxes. They were always friendly to the British, joining them in the Revolution as well as in the war of 1812. After the Black Hawk war they were removed to Iowa and from here removed again to the Indian Territory from 1842-46. Many of the tribes kept coming back to their old hunting ground and finally they were permitted to remain on the Iowa river and provision for them was made by the legislature. About 400, known as the Muskwaki, are still found, survivors of some of the early wanderers in eastern Iowa in the early thirties. The Sacs and Foxes and the Winnebagoes were always on friendly terms with the whites and were sworn enemies of the Sioux. Mrs. Susan Shields, a daughter of William Abbe, was on intimate terms with the Winnebago Indians, who used to gather at her father's home on Abbe's creek frequently. She learned to speak the Winnebago language, and remembered seeing many wigwams, or tepees as they were called, at the lower end of what is now Cedar Rapids. She speaks of the Indians as being kind to her and that her first playmates were Indian girls of her own age. Her brothers also played with the Indian boys and they learned to ride Indian ponies and to shoot with bows and arrows. No trouble ever arose among the young of both races in these days; rather the white boys were envious to see the liberties granted the Indian boys and how they were permitted to roam any place at pleasure, never having any chores to do.
