Fred Gregory and Steven Walske teamed up to write "2¢ Ship Fee On Mail From Hawaii via San Francisco, 1849-1852", found in The Chronicle, Volume 60,
No. 1, Whole No. 217, February, 2008. This article explains why the San Francisco Post Office sometimes did and sometimes did not show the United
States two cents ship fee on letters sent there from Hawaii and unravels the mysteries of San Francisco rate marks on incoming pre-paid ship letters. The
article is richly illustrated by some key covers passing from Hawaii through San Francisco in the early days of the San Francisco Post Office. The Chronicle
is the official publication of the U.S. Philatelic Classics Society and is free to members. The article was republished in Western Express, Vol. 58 No. 2,
Whole No. 228, June, 2008, p. 37-54. Western Express is the publication of the Western Cover Society, and is free to members. Information about
