I9II] ICE WAVES OF THE BARRIER 9 
but always starting from below the Barrier horizon. 
We never saw any that appeared close at hand. 
The temp, remained at - 50° all day, and Cherry and 
I both felt the cold of the snow very much in our feet on 
the march, he getting his big toes blistered by frostbite, 
and I my heel and the sole of my foot. A good many of 
Cherry's finger-tips also went last night at the edge of 
the Barrier and are bulbous to-day; but he takes them 
as a matter of course and says nothing, and he never 
once allowed them to interfere with his usefulness. 
The surface to-day was firm, generally ; hard and 
windswept in some places, and soft and sandy in others. 
The sledges to-day went heaviest on the harder areas for 
some reason, which was quite exceptional. I think there 
was a fixed deposit of gritty crystals on the apparently 
smooth surface. Always after this it was the soft sandy 
drifts which held us up more than anything else. 
We made two or three long sloping gradients to-day 
in our march going eastward. These also we confirmed 
on our return journey, when we recrossed three long 
low waves on about the same line, and I believe them to 
be the continuation of a series of extensive waves which 
run out from the point at which the glacier flow from 
Mt. Terra Nova runs into the Barrier. These waves 
curve gradually south-westward from the south-easterly 
direction in which they first join the Barrier. Hodgson 
and I followed up and roughly charted one of this group 
of waves in our journey in 1903 when we were examining 
the tide crack along the south side of Ross Island. They 
are very long and definite disturbances, and in our march
