The evidence
“With this treaty the United States obtained an unassailable title to all the lands lying within the present bounds of Rock County ; but, so fond of their former homes in this locality were the Rock River Winnebagoes, that even after they had been removed to the reservation provided for them, they continually revisited them, in small parties, to the great annoyance of the citizens ; and the Government was finally compelled, in 1841, to send a military detachment to secure obedience to the order confining them to territory set ofi" to them beyond the Mississippi. But, though forced to leave, they would frequently return in small parties ; and, when these straggling bands would pass their old-time burial places, they would manifest the deepest reverence.”
