As in all other measurements of this kind, the retarding 
influence of the sides of the glacier is manifest: the center 
moves with the greatest velocity.

The first stake of this line was quite close to the edge of 
the glacier, and the ice was thin at the place, hence its slow 
motion. Crevasses prevented us from carrying the line 
sufficiently far across to render the retardation of the fur- 
ther side of the glacier fully evident.

Comparing the three lines together, it will be observed 
that the velocity diminishes as we descend the glacier. In
