THE VISIT OF THE BRITISH DIBIGIBIJ;:, THE R-34, JULY, 10 ID. 



The Weather Bureau was called on for detailed information and 

 forecasts before, during, and after the visit of the R-34 to the United 

 States in July, 1919. The first call for information and forecasts was 

 from the R-34 by radio when she was in the vicinity of Newfound- 

 land, and then and after, until she had reached midocean on her re- 

 turn to Great Britain, the latest meteorological information and 

 forecasts were always at the disposal of the conmiander of this craft. 

 The following letter, addressed to the Chief of the Weather Bureau, 

 was received from the Secretary of the Navy concerning the work 

 of the Weather Bureau in connection with the visit of the R-34 to our 

 country :

Also there was received the following letter from the British air 

 attache in appreciation of the work of the AVeather Bureau in con-

 is claimed that meteorologj' is the handmaiden of aeronautics, but I think that 

 does not show the. science enough respect. At any rate, you, by your assiduous 

 jittontion to, and reading of, the weather during the visit contributed more 

 than a fair share to the success attained.
