‎I love even to see the domestic animals reassert their native rights — any evidence that they have not wholly lost their original wild habits and vigor; as when my neighbor's cow breaks out of her pasture early in the Spring and boldly swims the river, a cold grey tide, twenty-five or thirty rods wide, swollen by the melted snow. It is the Buffalo crossing the Mississippi.
