long-range balloons designed now for from two to three thou- 

 sand mile flights, and adjusted to maintain a constant altitude 

 and to drop in western Europe their records of average winds 

 in these heretofore unchartable regions. The importance of 

 this work for the future of aviation needs no emphasis. 



The success which the Meteorological Service has attained 

 would have been wholly impossible had it not been for the 

 intimate and effective cooperation which has been extended to 

 it in all of its projects by Director Marvin and the whole staff 

 of the United States Weather Bureau. The chief credit for 

 the work abroad should go to Major William R. Blair, com- 

 missioned from the Weather Bureau for the observational work 

 with the A. E. F. For the success of the service in this coun- 

 try Captain Sherry and Lieutenant Waterman have perhaps 

 the chief responsibility. Captain Murphy and Professor Fassig 

 have, however, contributed very important elements.
