THE AEROLOGICAL CONGRESS AT MONACO 

 The international study of aerology, as 

 the exploration of the atmosphere is now 

 called, was begun by a small commission, 

 including the writer as the American mem- 

 ber, which was appointed at an Interna- 

 tional Meteorological Congress held at 

 Paris in 1896. Although the commission 

 bears the title "International Commission 

 for Scientific Aeronautics," aeronautics 

 serves only as the means of obtaining 

 meteorological data in the free air. The 

 work of the organization rapidly extended 

 and five meetings were held in European 

 cities before the session this year, which, 

 by invitation of its honorary member, 

 Albert I., Prince of Monaco, occurred dur- 

 ing the first week of April in the new 

 Oceanographic Museum at Monaco. The 

 interest and importance of this, the sixth, 

 reunion, served to bring together about 

 thirty colleagues, from fourteen nations, 

 the writer representing the United States 

 Weather Bureau besides his own observa- 

 tory at Blue Hill, where the first aerolog- 

 ical observations in America were under- 

 taken. 



The meeting on April 1 was opened by 

 Professor Hergesell, of Strassburg, presi- 

 dent of the commission, who reviewed the 

 progress made in exploring the air since 

 the meeting at Milan three years ago, 

 dwelling particularly on the extensive co- 

 operation in the simultaneous series dur- 

 ing six days in July, 1908, when balloons 

 and kites were sent up from forty-four 

 stations on land and sea in the northern 

 and southern hemispheres. He empha- 

 sized the importance of determining the 

 direction of the wind at different heights
