Delta Line (Mississippi Shipping Co.)

  by Joe McMillan

Delta Line (Mississippi Shipping Co.), New Orleans (1919-85)
Service from Gulf of Mexico and east coast of South America; originally established by coffee merchants to ship Brazilian produce directly to the Mississippi Valley through New Orleans, bypassing New York. Officially the Mississippi Shipping Company until 1962, but was already known unofficially as the Delta Line long before that. The line's management failed to buy container vessels in the 1970s, lost so much money that its owners (by then the Holiday Inn Corporation) sold out to Crowley Maritime, the largest US barge and tug operator, in 1982. Crowley tried to modernize the fleet, but decided to cut its losses by selling Delta to United States Lines in 1985, which subsumed Delta's ships into its own fleet before going bankrupt in 1986. Flag green with a yellow Greek letter delta (a triangle). In 1949, Delta owned 14 ships, with a total of 98,000 grt.

Diamond Jack’s River Tours

image located by Jan Mertens, 30 September 2005

Diamond Jack’s River Tours (a family business) is based at Lincoln Park, Michigan, offering public as well as private tours showing the Detroit River and other interesting places. As could be expected, a (red) diamond is the company logo and appears on a white flag, touching the edges. The logo is in fact an upright diamond and the flag seems to contain one as well, being higher than long – see another picture.

Quote from the site’s history section, part of which already served illustrating Gaelic Tugboat Co.:

“With the change in the economy in the late 80's and early 90's, Bill (Hoey, jm) planned for the future. Harbor tours worked in other cities and Detroit was ideal for this type of activity. In 1991, he purchased a 65 foot former Arnold Line Mackinac Island ferry, the Diamond Jack, outfitted it as a sightseeing vessel, and launched Diamond Jack's River Tours. The company's two hour tours present highlights of the Detroit and Windsor, Ontario, Canada skylines, along with historical anecdotes about both cities(…)
In early 1993, Hoey purchased another Arnold Line ferry, christened the Diamond Belle. This 91 foot mini ship is used exclusively for group charters. These charters have become so popular that Bill added yet another Arnold Line vessel to the fleet, the Diamond Queen. (…) Also, longer cruises to Port Huron, Toledo, Sans Souci and Wallaceburg Ontario depart on scheduled dates throughout the summer season and are available to the public.”

Robert Dollar & Co.

  by Joe McMillan

Robert Dollar & Co. (Dollar Line), San Francisco (1900-38)
The Dollar Line was the main US trans-Pacific shipping line in the early 20th century. It originated as a schooner fleet in late1890s carrying lumber from Robert Dollar's sawmills in the Pacific northwest to markets in California. Dollar entered the regular merchant shipping business after the Spanish-American War, originally using British-flagged ships. He was very successful in the trade between the US west coast and the Far East and initiated around-the-world service in 1921. However, the company became heavily indebted while trying to expand in late 1920s and could not recover once the Great Depression set in. The line was bought out by the US Government in 1938 and the assets were then used to establish American President Lines. The two lines share red and ! wh! ite livery. The Dollar Line flag was red with a white dollar sign ($).

Donald Steamship Co.

Donald Steamship Co., New York
I know nothing about the company, but the flag is interesting--a Celtic cross (obviously connoting the Scottish origin of the Donald name) in red on a white field with blue border all around.

Dunham & Dimon

The mid-19th century New York firm of Dunham and Dimon operated coastwise service to Savannah, Georgia, and later a packet line connecting New York and Glasgow. I believe much of the Irish immigration that went through Glasgow in the 1850s went on Dunham and Dimon's ships. All these come from the chart I have been relying on extensively, Private Signals of the Merchants of New York, reprinted in the Time-Life book The Clipper Ships.
