To me two things I association with Panama are hats and the canal. As I have no stamps of hats I'll go straight to the canal
and the Canal Zone which had its own stamps for most of the 20th Century. These are the air mail stamps issued in 1931.
and this one which luckily has most of a rather nice 'short route' map cancellation,.
The building of the Panama must be one of the greatest civil engineering feats of the 20th Century. The French first attempted it but had not surveyed it properly and despite 21,900 workers dying from disease, landslides and accidents they were unsuccessful. The US also ran into trouble when they started it in 1904 but in 1907 the US President Theodore Roosevelt made an inspired appointment of the army officer and civil engineer George Washington Goethals as chief engineer. This was to change everything and the building of the canal was completed in 1914 (two years ahead of target). Goethals paid particular attention to sanitation and control of disease from mosquitoes and reduced the incidence of disease and death amongst canal workers. Despite this 5,600 still died but the toll would have been much greater without his efforts.
I now return to a little more of Mesoamerica
