twenty-five feet of beam and carried a crew of twenty-five all told. 
The island of Jan Mayen was reached about June 29th, and was 
found almost encircled with ice. Sailing along the edge of the 
main pack they endeavored to reach the east coast of Greenland, 
near Cape Bismarck, the farthest point reached by the Germans. 
On the 2d and 3d of July, they got among the bladder-nosed 
seals and shot over three hundred of these animals. ey 
worked in towards the west until the oth in 75° 4o’ latitude; but

They steered northward again on the 13th, and on the 16th
