Pierce Butler, Washington ex rel. Stimson Lumber Company v…
“ The tariff filed by the Northwestern Towboat Owners' Association shows that 50 owners held themselves out as engaged in the business of common carriers, including the towing of logs; and, for that purpose, they devote their towboats to the use of the public. They are common carriers, not because of legislative fiat, but by reason of the character of the business they carry on. The statute does not attempt to make all towboats common carriers. It application is limited to those operated in the public use for hire. ”
