analyzed in a preliminary way. On January 1, the data on physical 

 oceanoofraphy still awaited anah'sis. 



On the February cruise a series of 370 drift bottles were released : 

 on lines bearing 163° 30' true from Montauk Point and 130° 30' true 

 from Xew York. The same sets were repeated on the July cruise. 

 Returns from these series have been disappointingly few. Several 

 were picked up on the beaches along the North Carolina coast and 

 a few were returned from southern New England points. Not 

 enough are available to Avarrant conclusions as to currents in the 

 region.
