O. Henry - Heart of the West [Annotated]

Grease-us – a play on the name of Croesus

Eighteenth Century mariners called the petrel (a large sea bird) "Mother Cary's chicken."

crack-loo – a form of gambling in which coins are tossed high into the air with the object having one's coin land nearest a crack in the floor

The Menger Hotel was (and still is) a San Antonio landmark. Built in 1859 near the Alamo, its guests have included Robert E. Lee, U. S. Grant, Theodore Roosevelt, and Sarah Bernhardt.

suaderos – O. Henry uses this term in several stories. He probably meant "sudaderos," which are saddle blankets or pads. The term is also sometimes used to refer to pads that prevent the stirrup straps from rubbing the rider's leg. O. Henry undoubtedly picked up the word during his stay on South Texas ranches, but he probably never saw the word written, and "suaderos" was what he came up with many years later when writing. This annotator is grateful to Michael K. DeWitt of Oklahoma State University for explaining this reference.

Cambon snack – This term eludes definitive explanation. It might refer to the brothers Paul and Jules Cambon. Paul was the French ambassador to Great Britain from 1898 to 1920; in 1904 he negotiated the Entente Cordiale between France and Britain that was the basis for their alliance in World War I. Jules was the French ambassador to the U.S. from 1897 to 1902 and was the French ambassador to Germany at the outbreak of World War I.
