by John Marshall Harlan, Louisville Gas v. Citizens' Gas-Light Company…
“ Louisiana, etc., Co., ante, 252, just decided, it is held that the supplying of gas to a city and its inhabitants by means of pipes and mains laid under its public ways, was a franchise belonging to the state, and that the services performed as the consideration for the grant of such a franchise are of a public nature. Such a business is not like that of an ordinary corporation engaged in the manufacture of articles that may be quite as indispensable to some persons as are gas-lights. ”
