The difficulties of printing a map of the world in colours within the space of a postage stamp led to "minor" geographical inexactitudes, such as the annexation by the red colour, of the United States, the invasion of France by England, and the removal of the Cape of Good Hope out into the sea. But unlike the Dominican Republic's map stamp of 1900 it did not lead to complications with other countries.

Canada's Quebec Tercentenary issue includes some stamps of martial interest ([Figs. 309-311]), the 5 cents shows the French Governor Champlain's house in Quebec, round which a wide ditch was dug and breastworks were thrown up and cannon mounted to protect the colonists from the savages. Generals Wolfe and Montcalm are portrayed on the 7 cents, the 10 cents shows the old city and fort of Quebec in 1700, and the other denominations show incidents in the exploration of Canada and portraits of King Edward and Queen Alexandra, and of King George and Queen Mary.

Mexico. Mexican stamps from 1856 to the rise of Porforio Diaz demonstrate some of the political changes through which the country has passed, from Republic to Empire, and back to

Republic. Revolution has brought about provisional stamps of a rare order, such as the Guadalajara, Chiapas, and Campeche stamps of 1867-1868, and the more recent issues of the "Constitutionalist" party for Sonora (Figs. 312-314) and Tamaulipas (Fig. 315).
