Section 4 Aerial Warfare
It may be desirable to supplement what is said in the following letters by mentioning that the Declaration of 1899 (to remain in force for five years) was largely ratified, though not by Great Britain; that of 1907 (to remain in force till the termination of the third Peace Conference) was ratified by Great Britain and by most of the other great Powers in 1909, not, however, by Germany or Austria; that aerial navigation is regulated by the Acts, I & 2 Geo. 5, c. 4, and 2 & 3 Geo. 5, c. 22; and that an agreement upon the subject was entered into between France and Germany, on July 26, 1913, by exchange of notes, “en attendant la conclusion d’une convention sur cette matière entre un plus grand nombre d’états” (the international Conference held at Paris in 1910 had failed to agree upon the terms of such a Convention); and that Art. 25 of The Hague Convention of 1907, No. iv., was ratified by Great Britain, and generally.
