Edward Douglass White, Postal Telegraphcable Company v…
“ In the second place, as in terms the act empowered telegraph companies to establish reasonable rates, subject to the control which the act to regulate commerce exerted, it follows that the power thus given, limited of course by such control, carried with it the primary authority to provide a rate for unrepeated telegrams and the right to fix a reasonable limitation of responsibility where such rate was charged, since as pointed out in the Primrose Case the right to contract on such subject was embraced within the grant of the primary rate-making power. ”
