Edward Douglass White, Olsen v. Smith — Opinion of the Court
“ Neither the exemption of coastwise steam vessels from pilotage, resulting from the law of the United States, nor any lawful exemption of coastwise vessels, created by the state law, concerns vessels in the foreign trade, and, therefore, any such exemptions do not operate to produce a discrimination against British vessels engaged in foreign trade, and in favor of vessels of the United States in such trade. ”
