Aero mail service has been started in nearly every country in Europe, and many South American countries are also making plans for carrying mail by aeroplane. In May, 1919, Mr. Joaquin Bonilla, son of the President of Honduras, visited the United States to see about arranging to use New Orleans as one base and Tegucigalpha as another for the aero mail landing-places. Mr. V. H. Barranco, of Cuba, is also in this country for President Menocole, of Cuba, to arrange aero mail between Key West and Havana, Cuba. The French aerial mail service officially started on March 1, 1919, between Paris and Bordeaux, Marseilles, Toulouse, Brest, and St. Nazaire, under the supervision of the director of civilian aeronautics. THE PARIS-LILLE MAIL SERVICE.—The aeroplanes engaged in the Paris-Lille mail service which had been instituted in April, 1919, started from the Le Bourget aerodrome. The machines and pilots engaged had been lent to the postal authorities by the military authorities. A daily postal service has been started between Avignon and Nice also.
