McCormick Steamship Co.

 image by Joe McMillan

McCormick Steamship Co., San Francisco (1903-1940)
Not to be confused with the better-known Moore-McCormack Co, this line was a subsidiary of the Charles R. McCormick Lumber Company. In common with other major lumber barons, Charles McCormick saw operating his own shipping line as the key to the profitability of the lumber business. By 1916 he was serving all the major ports on the U.S. Pacific coast. He formally incorporated McCormick steamship in 1921 and continued growing until, in 1925, he moved to buy out the larger and older Pope and Talbot lumber company. The sale went through, but McCormick had tried to grow too fast--by 1928 he was operating a fleet of 45 vessels--and was unable to meet the payments on his debt to the former owners of P&T. So they repossessed not only the former P&T properties but McCormick Steamship as well. Pope and Talbot continued to operate the shipping line under its former name until 1939, when it became the Pope and Talbot Steamship Co. The house flag of McCormick was a white field with a blue star, and thereon a white disk bearing a red M. (I think I have also seen this with a "fat star," but National Geographic (1934) shows it in the usual form.)

Donald McKay's Clippers

image located by Jan Mertens, 29 August 2005

US and UK house flags having to do with Donald McKay, American 19C entrepreneur and clipper builder can be found at http://www.eraoftheclipperships.com/page66.html (see illustration above). The caption states:

"House Flags Carried by Donald McKay's Clippers

Top Left: Mssrs. Sampson & Tappan, Boston / Top Right: George B. Upton, Boston
Donald McKay House Flag
Lower Left: Grinnell & Minturn & Co., New York / Lower Right: James Baines & Co., Liverpool, England"

The George B. Upton, Boston, flag is white, a blue cross throughout. The date 1840 is added, and a number of sources, e.g., http://www.mysticseaport.org/library/initiative/SignalImage.cfm?PageNum=4&BibID=36294&ChapterNo=10, very last flag. Also in the `Private Signals of the Merchants of Boston' chart, but not in the `Private Signals… NY and SF'. Perhaps on the `Private Signals… NY' but that one is too small for me to read – could be the one on the very first row, though.

The Donald McKay, Boston, flag is white blue-bordered swallowtail that tapers with a blue eagle displayed within a blue ring. It can be found as a "swallowtail" 36.1.11, date 1850 added, on one single source at http://www.mysticseaport.org/library/initiative/SignalImage.cfm?BibID=36294&ChapterNo=36, flag at upper right. The bird is much more stylized.

Merchants and Miners Transportation Co.

Merchants and Miners Transportation Co., Baltimore (1852-1948)
Known as M&M, this was one of the largest companies in the Atlantic coastwise service. It was originally founded to connect Baltimore and Boston. After the Civil War it expanded to Providence and as far south as Savannah. By 1929, M&M was operating 18 ships up and down the Atlantic coast, now going all the way to Miami and it continued to grow slowly right up to the start of World War II when its fleet was requisitioned by the government. Rather than renewing the fleet after the war, the shareholders decided to scrap the old ships, forgo buying surplus vessels from the government, and dissolve the company. The flag of M&M was a long, medium-blue burgee with a white lozenge bearing the initials M&MTC.

Joe McMillan, 29 October 2001

Merchants & Miners Transportation Co. Inc. In point of fact some sources, including Lloyds 1912, show the flag as being a normal swallowtail instead of the tapered version, and most for either design show a small enhanced "o" after the "C". Talbot-Booth in 1938 states that it had "now" become the tapered version (but forgot to alter in his later books) but in view of the fact that this design was being shown long before I am uncertain whether this is the one and only design used with the variations resulted from the difficulty in working out such details by observation of a flying flag, or whether there was an actual change at some stage.

The company ownership is indicated by the initial of owner’s family name. See this trade card: http://www.artfullyredone.com/proddetail.asp?prod=TC-NP-A-GoodHope. I suppose the difference of the initial here is immaterial as probably caused by printing it inside a disk left white; the flag itself is drawn somewhat longer though. On this card the firm is (nick)named ‘The Merchants’ Express Line of Clipper Ships’ but also mentioned is ‘Randolph M. Cooley & Co.’.

The Morse shipping empire collapsed two years later leaving Metropolitan in bankruptcy. It was then absorbed into Eastern Steamship Lines in 1911. The flag was similar to that of Merchants Line for Washington, white with blue stripes at the upper and lower edges and the initials of the company, M.S.S.Co., in red.

Mittal

 image located by Jan Mertens, 22 October 2006

Source: http://www.nyse.com

A photo showing a Mittal flag has turned up which I would locate in the US as the fleet came with the firm and because I do not know of any other Mittal ships. The Mittal flag is flying behind the ‘Edward L. Ryerson’ swallowtailed onomast. It is a light blue field, white stylized letters ‘MITTAL’ in white. This image can therefore be raised to the rank of flag image from the NYSE website.
