Plate No. 6. 



THE LAST STAGES OF A BERG. 



June 22, 1922, 41° 32' N., 49° 45' W., water temperature 62°. The photograph shows ex- 

 treme disintegration of the berg, and the patrol is ready to strike it off the list of menaces 

 to navigation. It is now in the northern edge of the Gulf Stream, as is evidenced by the 

 water temperature and the warm-weather clouds to leeward.
