ch. xxxn] Franz Josef Land and its Explorers 297 
143 miles of ice-covered sea between Cape Mary Harms- 
worth, the northernmost point of Alexandra Land, and 
Cape Leigh Smith on North-east Land has not yet been 
explored. The sea to the east of Wilczek and Graham 
Bell Islands is also unknown. 
During the period from August 1872 to the following 
February the Tegethoff was drifted in a north-easterly 
direction from Cape Nassau of Novaya Zemlya, which 
is in longitude 62 0 E., to 71 0 38' E„ a distance of about 
125 miles, and from February to the next October, in 
latitude 79 0 N., she drifted westward until she reached 
the land ice on the south coast of Franz Josef. These 
drifts appear to have been due to the prevailing winds. 
The sea to the south of Franz Josef Land, between 
Spitsbergen and Novaya Zemlya, has received the name 
of the Barentsz Sea. Its greatest depth is 230 fathoms, 
and over the greater part of the area the depth is not 
more than 100 fathoms. The ice is always kept well out 
of sight of the European coast by the Atlantic current, 
and when the line of the pack is met with in about 74 0 N., 
it is found to be sufficiently loose for navigation north- 
wards during some part of the summer, the general drift 
being to the westward, but varying with the winds.
