A BERG WITH A BLUE STREAK. 



June 14, 1922, 43° 15' N., 50° 10' W. This picture of one of the few bergs on the Tail of 

 the Bank during 1922 was taken from the "Tampa." The dark streak in the center of the 

 berg was caused by a fissure, when in the glacier in Greenland, filling with water and 

 freezing. It was plainly distinguishable from the surrounding white snow ice by a clear, 

 dark-blue color.
