Palmer

Published serially in The Philatelic Gazette is "The Postal Issues of the Philippines" by Major F. L. Palmer.

The editions were from December 15, 1910, to May 15, 1912.

This dealt with the Spanish issues, Aguinaldo's revolutionary stamps, and the early American period.

In conclusion, "the author desires to say that it is based primarily upon 'The Postage Stamps of the Philippines' (Bartels, Foster, and Palmer, 1904), as added to by the experience and results of the writer both in the United States and while at Manila, during 1905-7."

Note the promotion in Palmer's rank: from captain (as indicated in the 1904 catalog) to major, in the U.S. Army.
