The Belgian Government moved to Havre in France on October 13, 1914, and there they have a special post office using the postmark _Fig._ 216. The headquarters of the habitations of the Belgian Government are reckoned part of Belgium, and while the Belgians may send letters to their different addresses in Havre or to Belgium, for the unit rate of 10 centimes (1d.), letters for France, even for another part of Havre, are treated as foreign letters, and require to be prepaid at the 25 centimes (2½d.) rate. There are also Belgian military postcards at present in use by the soldiers, and a variety of military postmarks, of which _Fig._ 217 is an example. [Illustration: 216 217] An interesting trio of covers has been received from a young marine who was with the Naval Brigade at Antwerp. The first, dated October 6, 1914, has the postmark (_Fig._ 218). [Illustration: 218 220] On the 11th he was evidently interned in Leeuwarden (_Fig._ 220) Holland, his letter being censored (_Fig._ 39). On the 27th he wrote from Groningen, where most of the naval brigade men were interned. The letter has the Groningen machine cancellation, and _Fig._ 221 struck in violet: PORTVRIJ FRANC DE POST. Militaires étrangers internés dans les Pays-Bas. [Illustration: 221] SERBIA. Revolutionary disturbances have assisted the changes of the stamps of Serbia. Michael Obrenovich III., who figures on the issue of 1866, was assassinated on June 10th, 1868, by the friends of the abdicated prince, Alexander Karageorgevich. Milan IV., his successor, had a troublous reign; during his period the country was recognised as a kingdom with Milan as king, but he abdicated in 1889 in favour of Alexander, his son. The portraits of Milan and Alexander figure on the stamps of their respective reigns, and in the case of Alexander we get one of those philatelic issues which must imprint on our minds the memory of notable or notorious events. It is within the memory of most of our readers that Alexander and his consort, Queen Draga, were assassinated by a number of military officers in 1903, and the house of Karageorgevich once again ruled in Serbia in King Peter, the present monarch. At the time of the assassination a new series of stamps bearing the portrait of Alexander was in readiness for issue, but before they were sent out under the new _regime_ the effigy of the murdered king was almost completely obliterated by the overprinting of a design of the Serbian Arms (_Fig._ 222). [Illustration: 222 223 224] The year following the grimmest of all the royal tragedies of Serbia the surviving dynasty commemorated its centenary, and issued perhaps the most sensational stamp series known to collectors. These will go down to posterity as the "Death Mask" stamps, although the curiosity of artistry which led to this designation probably owes more to the excited imagination of the Serbian and foreign public than to any gruesome intent on the part of revolutionary artists.
