Air Photography And Wireless Gh«ck-Up. INTERNATIONAL CONFERENCE. (Brltirtj Official Wireless.) (Received 12 noon.) RUGBY, July 12. Leading geographers from 47 countries will attend a congress next week at Cambridge, held under the auspices of the International Geographical Union. Many delegates are being received by the King at Buckingham Palace during the week and among other events piauned are a reception by the Royal Geographical Society, another by the Lord Mayor, Sir Charles Batho, at the Guildhall, which the Prince of Wales will attend, and a banquet at Cambridge, over which the Foreign Secretary, Sir Austen Chamberlain, will preside.

A particularly interesting feature of the congress will be the examination of the sections of a new world map, upon which experts have been engaged for many years.

Wireless has played an important part in its completion. There are 52 observatories scattered over the face of the globe and these, representing thirty nations, have taken part in the task of verifying the world's longitudes and in redetermining the configurations of the seas and continents.

Principal stations for several weekfi were exchanging radio telegraphic signals at the rate of 30 a day. Another factor in checking the world map has Deen the application of air photography to ordnance survey purposes.

Representatives of survey departments of the British Colonies and mandated territories are already in London and have been conferring on the methods of map making, as well as administrative matters, and several of them are going to Cambridge for next week's congress.
