ABSENCE OF TIDE CRACK

ourselves with them in that direction, we found we were 
still running into the same crevassed mounds and ridges, 
so, finding a hollow with deeper snow in it, we camped 
for the night, and decided to wait until we could see 
exactly where we had got to. 
The absence of a well-marked tide crack — which had 
rather puzzled us in the Discovery days — in the crossing 
of land-ice slopes such as Terror Point (Cape McKay) 
and the ' second snowcape,' both of which come straight 
down from Terror and run into the pressure ridges, was 
a question which we had in our minds all these days. 
We assuredly did cross several small cracks on these slopes 
which had the appearance of a certain amount of working, 
but their breadth was a matter of a couple of inches only, 
and if tidal they must take up only an insignificant 
fraction of the movement. They are so small that 
they may easily have been obscured by snowfall in the 
old days. Bowers is convinced they are to be considered 
tidal cracks. I am not so sure myself, and hope to have 
a better view of them by daylight before deciding whether 
there is anything to take up tidal movement besides the 
pressure ridges, which seem to me more than sufficient. 
This day the temp, ranged from - 367^ up to - 27°, 
with light airs northerly and southerly. 
Some hours after midnight it began to blow and to 
snow more heavily. 
The min. temp, for the night was - 24*5° up to noon
