John McLean, Fanning v. Gregoire — Opinion of the Court
“ The defendants, in their answer, admit that the plaintiff has a charter to ferry across the river Mississippi at Dubuque, but they deny that it secures to him an exclusive right. And they say that their steam ferry-boat was put on and is run by them in accordance with a contract made with the city of Dubuque, authorizing the running of said boat for six years, from the first day of April, 1852; and they say that in running said boat they do not interfere with the right of the plaintiff other than such interference as is necessarily the result of a fair competition. ”
