Charles Dant’s lumber-shipping interests and Columbia Pacific Steamship, formed in 1919, preceded States Steamship, dated here to 1921 with steamship ownership from 1923. In 1928 he dropped the Columbia Pacific name and used States Steamship or States Line. Other service names included Quaker, Oregon Oriental and Pacific-Atlantic. European service ended by the 1930s and business later centred on the Philippines. Foreign competition, failure to containerise and high fuel costs led to bankruptcy in the late 1970s.
The source lists Pacific Atlantic and United Fruit Steamship among subsidiaries, the latter managed by United Fruit. Pacific Atlantic and States appear reciprocally as operators in different publications.
