I. Flotation. — Let us first of all consider the question of 
the flotation of tJie Barrier. There can be, I tliink, no 
doubt that it is afloat. On pages 417-420 in tJie ' Narrative 
of tlie Discovery ' will be found an aecount of the Ross 
Barrier, in which we read that its face is 360 miles long, 
and tliat tlie sea exceeds 1800 feet in depth along the 
greater part of tliis distance. 
Tiie ice wall is i c;o feet higli Jiere in places, and we must 
allow for a mucJi greater depth which is submerged 
below tJie level of tlie sea. 
Tlie ratio of submerged to visible ice appears to vary, 
and sJiould be investigated on bergs in our vicinity.
