MAILING FORMS 



21. At the end of each return voyage to a United States port, mail original copies of Form 1210 — Marine 

 and the duplicate copies of Form 1204 to the Weather Bureau office from which the observer receives his 

 instructions. Special envelopes, which require no additional postage, will be provided for the purpose. 



SPECIAL OBSERVATIONS 



22. Occasionally special observations will be taken and forwarded by radio. They may be taken on the 

 initiative of the vessel master when unusual weather conditions exist, or on call by the United States Weather 

 Bureau in connection with special service. Such special observations will follow the same procedure as in 

 regular observations, care being taken to indicate accurately the time the special observation is taken. 



The following is a sample of Form 1210 — Marine with an observation entered and coded.
