Pacific Mail Steamship Co. was acquired by Grace Line in 1916. Pacific Mail also ran a trans-Pacific
service with the President liners operated on behalf of the U.S. Shipping Board.When the Shipping
Board sold the ships to Dollar Line in the mid-1920s, Grace Line decided to sell the Pacific Mail name
and goodwill to Dollar Line. Grace Line then organised Panama Mail Steamship Co. to operate the
remaining Pacific Mail routes, the intercoastal route between San Francisco and New York and the
local route from San Francisco to several Central American ports as far south as Panama.

Note the apparent similarity between the Pacific Mail brochure on this page and the
Panama Mail brochure from c. 1926 or 1927.
(There is also a Panama Mail brochure from 1925 having exactly the same cover
design as the brochure on this page.)

The Colombia (5,644 grt, 379 ft. long) was built in 1915, together with sisters Ecuador and Venezuela.
They were moved from the trans-Pacific to the intercoastal service in 1921, and transferred to Panama Mail
in 1925. The Colombia was wrecked in California in 1931.
